DESCRIPTION FIELD [001] This description refers to the identification of soil compaction in a workplace. More specifically, the present description refers to the generation of control signals to control an operation based on the identified soil compaction.
FUNDAMENTALS [002] Mobile machines work in a variety of different types of workplaces. For example, agricultural machinery works in a field. Construction machines work at a construction site. Lawn-growing machines operate in grass-growing sites. In all of these locations, mobile machines can be machines that are propelled with wheels or caterpillars or other elements engaging the ground. Consequently, machines can cause soil compaction in the areas over which they move.
[003] Soil compaction can impact several items in the workplace. For example, at a construction site, soil compaction can affect the equipment's ability to penetrate the ground, and it can also affect the traction of mobile machinery over the job site. In a grass-growing location, or in an agricultural field, soil compaction can also affect the performance of the lawn or crop. If the soil becomes highly compacted around the lawn or cultivation, this may mean that less water and less nutrients can reach the roots of the plant, because the soil is more difficult to penetrate. This can affect lawn growth and crop yield.
[004] This problem can be exacerbated in crops that are perennial crops or that can be without replanting for several years. Such crops can include such products as sugar cane, alfalfa, etc. In these
Petition 870180003542, of 01/15/2018, p. 68/126 / 40 types of scenarios, soil compaction can accumulate over years and exacerbate the problems caused by soil compaction.
[005] As an example, sugar cane is a “perennial” crop or a crop that only needs to be replanted after several years. Some sugarcane operations are very large, and can include as many as 50-150 cultivation machines organized on fronts. Each front can have 5-10 harvesters with 10-20 tractors (and corresponding carts). Each front may also have one or more semi-trucks to transport the sugarcane from the field to the processing facility. All of these different mobile machines can move through some or all of the sugarcane field during harvesting operations. The soil compaction caused by these machines moving over the field can be detrimental to the performance of the sugarcane harvest.
[006] In order to measure soil compaction, some current systems include measurements of mass density or soil cone penetrometer. Some current systems also use Bolling pressure samples, or other similar devices. These measurement methods are relatively time consuming and depend on the user's experience and skill. In addition, they are only locally applicable. The measurements are only made in parts of any given field, and therefore the results are incomplete. They do not offer a complete assessment of the field's compaction status. Also, because measurements can be interpreted in different ways, there is a relatively high uncertainty corresponding to these types of measurements. In addition, they can be invasive and can potentially damage the crop.
[007] The above discussion is merely provided for general background information and is not intended to be used as an aid in determining the scope of the claimed matter.

DETAILED DESCRIPTION [0018] Figure 1 is a block diagram of an example of a mobile machine architecture 100. Architecture 100 illustratively includes the mobile machine 102 which has an operator 104. The mobile machine 102 can also communicate with one or more remote systems 106 over a network 108. Network 108 can be any of a wide variety of different types of networks, such as a wide area network, a local area network, a cellular network, a field communication network next, to a network involving storage and transmission technology, among a wide variety of others, some of which are described in more detail below. [0019] The mobile machine 102 can be any of a variety of different mobile machines, such as an agricultural machine, a construction machine, the lawn cultivation machine, among others. Just as an example, the mobile machine 102 can be a sugar cane harvester, a combine harvester, a tractor, or any of a wide variety of other agricultural machines.
[0020] The operator 104 illustratively interacts with the mobile machine 102 through one or more operator interfaces 110, in order to control and manipulate the mobile machine 102. The operator interfaces 110 may include, for example, pedals, levers, a steering wheel, a control lever, a visual display, touch-sensitive display elements (such as icons, links, buttons, etc.), or a wide variety of other user interfaces. User interfaces 110 can include a wide range of
Petition 870180003542, of 01/15/2018, p. 71/126 / 40 variety of user input mechanisms, and they can also include exit mechanisms. Exit mechanisms can include, for example, audible exit mechanisms, tactile exit mechanisms, visual display mechanisms, or a wide variety of other items.
[0021] Architecture 100 also shows that mobile machine 102 can receive soil data 112 and historical compression map data 114. Data items 112 and 114 can be received over network 108 from one or more remote systems 106, or they can be received directly, such as through an operator input or otherwise. The soil data 112 can include a wide variety of different types of information about the soil on which the mobile machine 102 is moving. For example, they can include soil type, soil moisture level, or a wide variety of other soil characteristics. Historical compaction map data 114 can represent a historical compaction map that is indicative of the state of soil compaction based on historical activities or a direct measurement, for example. The map can reflect, for example, the estimated or measured soil compaction, across the entire geographical area of the workplace (for example, field) given its type of soil, given the number of historical passes over the soil by the mobile machine 102 or other mobile machines, the place they pass, etc. This information can be used, as described in more detail below, by the mobile machine 102 in order to identify the additional passing effect of the mobile machine 102 (and other machines) on the soil on the soil compaction. This can be used to generate additional information, such as the effect of soil compaction on the estimated yield of the crop. This can also be used by the mobile machine 102 to generate control signals to control various aspects of the mobile machine 102 in order to, in turn, control the amount of compaction that the mobile machine 102 will have on the ground.
Petition 870180003542, of 01/15/2018, p. 72/126 / 40 [0022] In the example shown in figure 1, the mobile machine 102, itself, illustratively includes one or more processors or servers 116, a plurality of different sensors 118, the database 120, the aggregation logic 122, skid estimate logic 124, communication system 126, mapping system 128, production impact determination system 130, control signal generator 132, one or more controlled systems 134, and may include a wide variety of other machine features136. Sensors 118 may include position sensor 138, wheel speed sensor 140, tire pressure sensor 142, soil type sensor / indicator 144, vegetation index sensor / indicator 146, cultivation 148, climate sensor 150, and may include a wide variety of other sensors or machine data indicators 152 (such as sensors or inputs, which indicate the number of axes on machine 102, machine weight 102, etc.) .
[0023] The mapping system 128 may include logic to generate a single soil map, or to generate a soil map for the topsoil and a soil map for the subsoil. In one example, system 128 includes soil compaction stress mapping logic 154, soil compaction stress mapping logic 156, and can include a wide variety of other items 158. Controlled systems 134 can include the route planning system 160, propulsion / steering system 162, tire pressure system 164, alert / user interface (UI) system 166, and may include a wide variety of other items 168. Before describing the overall operation of the mobile machine 102 in more detail, a brief overview of some of the items on the mobile machine 102, and its operation, will first be provided.
[0024] The position sensor 138 illustratively detects a geographical position of the mobile machine 102 and generates a position signal indicative of this position. Sensor 138 can be, for example, a receiver
Petition 870180003542, of 01/15/2018, p. 73/126 / 40 global positioning (GPS), a passive recognition sensor, a cell triangulation sensor, or a wide variety of other sensors. The wheel speed sensor 140 illustratively detects the speed of the wheels or tracks that drive the mobile machine 102. The tire pressure sensor 142 illustratively detects the tire pressure of the tires that support the mobile machine 102. The type sensor / indicator Soil 144 may be a sensor that detects the type of soil in the soil on which the mobile machine 102 is traveling. It can also be an input mechanism that allows the operator 104 to feed the soil type, or that allows the mobile machine 102 to receive an indication of the soil type (such as through soil data 112 or otherwise). The vegetation index sensor / indicator 146 may also be a sensor that detects vegetation cover in the field (or at another work site) over which the mobile machine 102 is moving, or it may be an input mechanism that receives the representation of the vegetation cover. For example, the amount of the field (or workplace) that has vegetation coverage (or the vegetation index) can be derived from, or indicated in, a collection of satellite images of the field. The satellite image collection can be received automatically, such as from a remote system 106, or can be powered by operator 104, or otherwise.
[0025] The cultivation site sensor / indicator 148 can be a sensor on the mobile machine 102 that actively detects a harvest site. For example, some harvesters or other equipment have deflectable fingers that are deflected by the harvest when the mobile machine 102 passes over the harvest. The deflectable fingers indicate a relative position of the crop, in relation to the mobile machine 102. There are also other crop sensors, which can detect the position of the crop in the field, or in relation to the mobile machine 102, or otherwise. In another example, a kinematic model is used that models the constant displacement of the various
Petition 870180003542, of 01/15/2018, p. 74/126 / 40 devices moving across the field, such as a combine harvester, seeder, etc. For example, a GPS receiver location that indicates the location of a GPS receiver in a row unit may allow the projection or estimation of the cultivation site based on the location of the GPS receiver. In another example, sensor / indicator 148 may be a map of the crop location that was generated when the crop was planted. The map can be fed through an interface or input mechanism to the mobile machine 102 or automatically (as downloaded from a remote system 106) or by the operator 104, or otherwise.
[0026] The climate sensor 150 illustratively generates a signal indicative of current climate or weather or recent climate or weather in the field (or workplace) where the mobile machine 102 is operating. The sensor / indicator 150 can be one or more sensors on the mobile machine 102 that actively detect the climate or weather, or an input mechanism that receives this information from a meteorological site or other remote system 106 or automatically, or based on an input by the operator 104.
[0027] Other machine data sensors 152 can include a wide variety of different types of sensors. They can be sensors that detect characteristics in the environment around the mobile machine 102, or that detect characteristics of the mobile machine 102 itself. They can be settings or configuration entries that identify the configuration of the mobile machine 102, or they can be entries that indicate other characteristics of the mobile machine 102, such as its weight, the number of axes it has, or a wide variety of others. information.
[0028] The aggregation logic 122 illustratively receives the position signal emitted by the position sensor 138 and aggregates the geographical position of the mobile machine 102, indicated by this signal, over time. In doing so, it illustratively generates a map 170 that maps the passes of the mobile machine 102 over the field (or the workplace) in which it is operating.
Petition 870180003542, of 01/15/2018, p. 75/126 / 40
The pass map 170 can be in the form of a route map showing the route of the mobile machine 102, or it can be in the form of another representation of the passes that the mobile machine 102 made on the field in which it is operating. [0029] The skid estimate logic 125 illustratively receives the position signal from the position sensor 138 as well as the wheel speed signal from the wheel speed sensor 140. By comparing these two signals, the skid estimate 124 can estimate whether the mobile machine 102 is skidding when it moves over the ground, or whether its traction is relatively constant. The degree of slippage can be used as an approximation to the level of surface moisture (topsoil). Based on the slippage estimated by the skid estimation logic 124, logic 124 (or other logic) can illustratively generate a surface / soil moisture metric 172 that is indicative of field surface conditions, or soil moisture conditions of the field over which the mobile machine 102 is traveling. For example, if the field is relatively dry, this can be identified by the fact that the skid estimation logic 124 is estimating a relatively small skid from the mobile machine 102, and, consequently, better traction. However, if the soil is relatively wet (or muddy) then this can be identified by the fact that the skid estimation logic 124 is estimating a relatively high degree of skid for the mobile machine 102 when it passes over the ground. It will be noted that, in order to generate the surface / soil moisture metric 172, the skid estimation logic 124 can also receive other information, such as weather information from climate sensor 150, the type of soil information from sensor / soil type indicator 144, or information from any other sensors 118 (such as soil conductivity sensors) or other inputs.
[0030] The mapping system 128 illustratively generates maps
Petition 870180003542, of 01/15/2018, p. 76/126 / 40 indicating the tension under which the soil is, based on its compaction. The soil compaction stress mapping logic 154 illustratively generates a map indicating the soil surface stress caused by compaction, while the soil compaction stress mapping logic 156 illustratively generates a map indicating the stress on the subsoil, with based on their compression. The compaction stress maps illustratively identify areas of high stress (or high compaction) and areas of low stress (or low compaction). They also illustratively indicate the location of crops and areas that may be more or less sensitive to compaction, such as the plant location, the corresponding root zone, etc.
[0031] The production impact determination system 130 illustratively uses sensor signals from sensors 118 and mapping system 128 (such as the soil compaction surface stress map and the subsoil compaction stress map and a historical production map showing the historical production for the field in which the mobile machine 102 is operating), and determines an impact on production based on the soil compaction stress. This is described in more detail below with respect to figure 3.
[0032] Also, as described in greater detail below with respect to figure 2, the control signal generator 132 can identify sensitive areas in the field (or receive this information from another item), where compaction is most likely to affect production , and generates control signals to mitigate compaction in those areas, where desirable. For example, control signal generator 132 can identify (or receive) the plant location and the root zone for the plants, based on signals from sensors 118. These can be a highly sensitive area, in which additional compaction can significantly affect production. It can then illustratively generate control signals to control the systems
Petition 870180003542, of 01/15/2018, p. 77/126 / 40 controlled 134 to mitigate compaction in those areas. In doing so, and as described in more detail below, you can implement a cost function that represents the cost of additional compaction in different areas of the field. For example, the cost function may indicate that it is relatively expensive to apply more compaction to a highly sensitive area in the field (for example, very close to the growing site or its root zone), while the cost is relatively low for applying additional compaction outside these areas (such as between rows of cultivation). The criteria considered in the cost function can include a wide variety of different types of criteria. For example, the fact that a tractor pulling more than one wagon will apply (in combination) more compaction than the same tractor pulling a single wagon. However, the cost of having to change tractor wagons more often may justify additional compaction at some point. The criteria can be identified empirically, they can be identified by the machine learning system, or they can be identified in other ways. Also, the application of a cost function is only one way to generate control signals and others can also be used.
[0033] Controlled systems 134 can include a wide variety of different types of controlled systems. For example, the route planning system 160 can be used to plan a route (for example, a geographic route) from the mobile machine 102 through a field (or workplace). The control signals generated by the control signal generator 132 can cause the path planning system 160 to plan a route that mitigates the effect of additional compaction on the soil in the field.
[0034] The propulsion / steering system 162 can be used to control the speed and direction of travel of the mobile machine 102. The control signal generator 132 can generate control signals so that the
Petition 870180003542, of 01/15/2018, p. 78/126 / 40 speed and direction of the mobile machine 102 conform to the path generated by the path planning system 160.
[0035] The tire pressure system 164 can be used to detect and control the tire pressure when the mobile machine 102 is propelled by tires engaging the ground. The control signal generator 132 can generate control signals to control the tire pressure, such as to decrease the tire pressure when the mobile machine 102 is traveling over high impact areas or highly sensitive areas, and to increase the pressure of tires when not moving in such areas. This can achieve multiple goals of increasing fuel efficiency with a higher tire pressure, but of decreasing soil compaction with a lower tire pressure.
[0036] The alert system / UI 166 can be used to alert an operator 104 to various things, such as when the mobile machine 102 is approaching an area of high sensitivity, or when the mobile machine 102 is invading, or already is being driven over, an area of high sensitivity. It can send such alerts to a remote system 106, and it can generate alerts and instructions indicating that operator 104 must change course, change tire pressure, etc. It can also generate a wide variety of other user interfaces.
[0037] Controlled systems 132 can properly include sensors that generate signals that can be communicated, using communication system 126, to remote systems 106. For example, when an operator is frequently driving over areas of high sensitivity, this it can be communicated to remote system 106, where a manager or someone else can contact an operator to take corrective action. This is just an example.
[0038] The communication system 120 can include any of a wide variety of different types of communication systems. The system of
Petition 870180003542, of 01/15/2018, p. 79/126 / 40 communication 126 can, for example, be configured to communicate with remote systems 106 over network 108. It can be a cellular communication system, a satellite communication system, a near field communication system , and / or any of a wide variety of other communication systems. Some of these are described in more detail below.
[0039] Figure 2 is a block diagram showing an example of control signal generator 132, in more detail. In the example shown in Figure 2, the control signal generator 132 includes illustratively the sensitive area identifier 180, the dynamic adjustment signal generator 182, and can include a wide variety of other items 184. The sensitive area identifier 180 illustratively generates a representation of sensitive areas 184 that can be provided, along with the vehicle location / path indicator 186 for the dynamic setting signal generator 182. The vehicle location / path indicator 186 can be provided by the position sensor 138 (shown in figure 1) or by the path planning system 160, and illustratively represents a location and / or current path (s) for the mobile machine 102. The dynamic adjustment signal generator 182 can then generate control signals to control the controlled systems 134 to modify the location and / or the path of the mobile machine 102 so that it is positioned away from sensitive areas 184 or otherwise mitigates the effect of compacting additional soil.
[0040] The sensitive area identifier 180, in one example, includes the plant location logic 188, the root zone extrapolator logic 190, the machine / soil data influence determination logic 192, the cost function 194, and may include other items 196. The dynamic adjustment signal generator 182 illustratively includes the tire inflation signal generation logic 198, the direction signal generation logic 200, the signal generation logic path plan 202, the logic of
Petition 870180003542, of 01/15/2018, p. 80/126 / 40 warning signal generation / other UI 204, and may include other items 206.
[0041] The plant location logic 188 illustratively identifies a plant location in the field. This can be generated based on the farm site signal generated by the farm site sensor / indicator 148 or derived based on the location of the vehicle or apparatus, as discussed above. The root zone extrapolator logic 190 then extrapolates a root growth function to identify a root zone surrounding the plant location. For example, in a field with a crop of sugarcane sprouts (such as a sugarcane field) when the sugarcane is cut, the root grows more widely for a reason that can be estimated based on weather conditions, soil type, applied nutrients, etc. Thus, the root zone extrapolator logic 190 can determine the number of times the sugarcane plant has been cut, and how recently it has been cut, and extrapolate a root growth function to identify a zone estimate of roots surrounding the plant. The plant location and the root zone can be combined to identify the sensitive area 184 in relation to the given plant, or crop.
[0042] The machine / soil data influence determination logic 192 uses machine data and soil data (which can be generated by either sensor 118 or the soil data 112 received by the mobile machine 102) to determine the influence on soil compaction that the machine will have. This will be influenced not only by soil type and soil conditions, but also by machine parameters or data. For example, if the machine is relatively heavy and has a relatively small number of axles with relatively high tire pressure, or relatively thin steel tracks, then the impact of the machine moving over a sensitive area will be at a first level. However, if the machine is lighter, with more axles, and lower tire pressure (for example, it has a larger footprint),
Petition 870180003542, of 01/15/2018, p. 81/126 / 40 or with relatively wide rubber tracks, then the impact of the machine moving over a sensitive area will be relatively lower.
[0043] The cost function logic 194 illustratively applies a cost function that generates a value indicative of a machine cost moving over different areas of the field. For example, the value generated by the cost function may illustratively fall when the machine moves further and further away from a plant location, and the root zone (for example, when it moves further away from sensitive areas 184 ).
[0044] Based on this information, the alarm signal generation logic / other UI 204 can generate control signals to control the alert system / UI 166 (shown in figure 1) to alert the operator 104 to control the mobile machine 102 in order to avoid further compaction in sensitive areas 184. The tire inflation signal generation logic 198 can generate control signals to control tire pressure system 164 (shown in figure 1) to reduce tire pressure when the mobile machine 102 is moving over a sensitive area 184, and to increase tire pressure when it is not moving over said sensitive area, based on the cost function value provided by the cost function logic 194. The logic direction signal generation 200 can generate control signals to control the propulsion / steering system 162 to avoid further compaction in sensitive areas 184. The path plan signal generation logic 202 can generate s control signals to control the path planning system 160 to plan a path in which further compaction is also avoided, in sensitive areas 184. In another example, controlled traffic farming can be carried out. In this scenario, a designated traffic area (or sacrificial area) is identified and the equipment is controlled to stay in this area. This can result in high compaction, but less total compaction across the field.
[0045] Figure 3 is a more detailed block diagram showing
Petition 870180003542, of 01/15/2018, p. 82/126 / 40 an example of the production impact determination system 130. In the example shown in figure 3, system 130 illustratively includes the normalization logic 219, the historical compaction impact correlation logic 220, the adjustment logic of projected production 222, the production impact map generation logic 224, and can include other items 226. Normalization logic 219 reduces the impact of year-to-year differences on correlation metric 221. For example, it can use expectation and sigma environments to normalize historical production versus forecasted production based on a statistical distribution of production over previous years. In another example, logic 219 can identify “desire zones” based on agronomic and land parameters (for example, soil, access to water, type of soil, etc.) and consider average production as a neutralization parameter . The historical compaction impact correlation logic 220 illustratively identifies the historical impact that soil compaction has had on production and generates a 221 correlation metric that correlates the impact of compaction in certain areas in relation to a crop, with production for this harvest. This correlation metric 221 can be generated based on historical compaction map data 114 (shown in figure 1) and historical production information that can be received by logic 220. By comparing historical production values with the compaction map historical, the 221 correlation metric can be identified.
[0046] The projected production adjustment logic 222 can receive or generate a projected production map for the field, indicative of a projected production from various geographical areas of the field. It can then adjust the projected production based on the 221 correlation metric generated by logic 220, and based on the topsoil and subsoil compaction stress maps, generated by the topsoil compaction stress mapping logic 154 and stress mapping
Petition 870180003542, of 01/15/2018, p. 83/126 / 40 compaction of the subsoil 156 (shown in figure 1), respectively. The production impact map generation logic 224 then illustratively generates a production impact map 228 showing the impact on production for the current field, based on soil compaction that already exists, and / or is designed based on in other field operations. Production impact map 228 can be used by operator 104, or by a manager on a remote system 106, or otherwise, to modify operations to reduce the impact of soil compaction on production.
[0047] It will be noted that this information can be generated for each field, for each operator or otherwise. Corrective action can be identified by individual operators, by individual fields, or by combinations of these and other aggregation criteria.
[0048] Figures 4A and 4B (collectively referred to here as figure 4), illustrate a flowchart showing the operation of machine architecture 100 (including control signal generator 132 and production impact determination system 130), in the generation of control signals to control various items, based on the various metrics and soil impact characteristics that are detected or generated. It is first assumed that the mobile machine 102 is functioning and moving over a field (it could be any workplace, but in the present example, it is an agricultural field). This is indicated by block 240 in the flowchart of figure 4. At some point, the mapping system 128, the production impact determination system 130 and / or the control signal generator 132 illustratively obtain the properties or characteristics of the machine in relation to machine 102. This is indicated by block 242. They can be obtained from sensors 118, as indicated by block 244. They can be obtained from a database (such as database 120 which stores those properties ) or from user input or other
Petition 870180003542, of 01/15/2018, p. 84/126 / 40 entries. This is indicated by block 246. The machine properties can include a wide variety of different properties, such as the number of axles 248, the weight of the machine 250, track / tire parameters (such as track width or inflation pressure tires, etc.) 252, or a wide variety of other 254 machine properties.
[0049] Systems 128 and 130 and generator 132 also then illustratively obtain the properties of the workplace (for example, field). This is indicated by block 256. Such properties can again include a wide variety of information. The properties can include historical production data 258, a vegetation index 260, and historical compaction data 262. They can be obtained from sensors 118 or from a database, as indicated by block 264. They can include the type soil 266, weather information 268, cultivation site 270, and a wide variety of other information 272.
[0050] The mapping system 128, the production impact determination system 130, and / or control signal generator 132 then illustratively obtain the operating variables. This is indicated by block 274 in the flowchart of figure 4. The operating variables can be obtained directly, or derived from the sensor data or other information. Operating variables can include position 276 indicating the position of the mobile machine 102. They can include travel speed 278 and wheel speed 280, which indicate the travel speed of mobile machine 102 (as derived from GPS data) , and the wheel speed, such as from the wheel speed sensor 140, respectively. They can include the surface / soil moisture metric 172 (described above with reference to figure 1), and the map or number of passes 170 (also described above with reference to figure 1). Operating variables can also include a wide variety of other variables 282.
Petition 870180003542, of 01/15/2018, p. 85/126 / 40 [0051] Also, at some point, the sensitive area identifier 180 generates the representation of sensitive area 184 that represents areas in the field that will be sensitive to additional soil compaction with respect to production. The determination of these types of impact zones on production in the field is indicated by block 284 in the flowchart of figure 4. As discussed above with respect to figure 2, this can be done by identifying the plant's location, as indicated by block 286, and extrapolating the root zone, as indicated by block 288, and then identifying impact zones on production (or sensitive areas) from that information, as indicated by block 290. Impact zones on production can also be determined over a wide range variety of other ways, and this is indicated by block 292.
[0052] The mapping system 120, and in particular the logic for mapping topsoil compaction stresses 154 then generates a topsoil compaction impact map (or map of stresses). This is indicated by block 294 in the flowchart of figure 4. As discussed above, the top soil compaction impact map (or stress map) can indicate the stress on the different geographical areas of the field, due to soil compaction. This can be based on historical soil compaction, based on estimated future soil compaction, or both.
[0053] Similarly, the underground compaction stress mapping logic 156 illustratively generates an underground compaction impact map (or stress map). This is indicated by block 296. The subsoil compaction impact map (or stress map) can indicate the same thing as the topsoil compaction impact map (or stress map), but with respect to the field subsoil as opposed to topsoil. It can also indicate other things.
[0054] The historical correlation impact correlation logic
Petition 870180003542, of 01/15/2018, p. 86/126 / 40
220 (shown in figure 3) then accesses a previous production map for the field. This is indicated by block 298 in the flowchart of figure 4. The previous production map can identify the field's production for one or more previous harvest stations. The historic compaction correlation logic 220 then generates the correlation metric 221 which indicates a correlation between soil compaction in sensitive areas 184, and crop yield. For example, it identifies a change in crop production based on a change in soil compaction in the field, in sensitive areas, and generates the 221 correlation metric based on this comparison. The comparison can be made based on the previous production map and the impact maps of topsoil and subsoil compaction. The generation of the correlation metric 221 is indicated by block 300 in the flowchart of figure 4. The metric can also be influenced by any (any) normalization value (s) generated by the normalization logic 219.
[0055] The projected production adjustment logic 222 then generates a projected production impact map based on the compaction correlation metric 221. This is indicated by block 302. For example, it can apply the compaction correlation metric 221 to a projected production map for the field to fit the projected production map, based on the 221 compaction correlation metric. As an example, the projected production map may project production to the field, but do not consider the effect of additional soil compaction on production. The projected production adjustment logic 222 can apply the correlation metric 221 to adjust the projected production values for the field, based on the additional soil compaction that has occurred, or is estimated to occur in the field. The application of the compaction correlation metric 221 to the projected field map is indicated by block 304. [0056] The impact map generation logic 224 can then generate a map showing several items. For example, it can show areas of
Petition 870180003542, of 01/15/2018, p. 87/126 / 40 avoidable compaction where, if future operations are adjusted, such as changing the vehicle path, changing vehicle types or vehicle characteristics (eg vehicles with more axles, lower tire pressure, etc.). ), additional compression can be avoided, at least to some extent. The identification of avoidable compaction is indicated by block 306. The projected production impact map generation logic 224 can generate production impact map 228 to also show a wide variety of other items, and this is indicated by block 308.
[0057] The control signal generator 132 then generates any control signals desired to control the controllable systems (or the controlled systems) 134 based on the compaction impact maps, the projected production impact map, in the compaction areas preventable, in production impact zones (or sensitive areas 184), in machine properties, workplace properties and / or operating variables. This is indicated by block 310 in the flowchart of figure 4.
[0058] This can take a wide variety of different forms.
For example, the path plan 202 signal generation logic (shown in figure 2) can generate path planning control signals indicating a suggested (or forward) path change based on a currently planned route and avoidable compression identified by the production impact map 228. The generation of the path planning control signals to change the suggested route is indicated by block 312 in the flowchart of figure 4. The direction signal generation logic 200 can generate direction control signals direction to avoid production impact zones (or sensitive areas 184) automatically when the mobile machine 102 moves across the field. This is indicated by block 314 in the flowchart of figure 4. The tire inflation signal generation logic 198 can generate tire inflation control signals to change the tire pressure, based on the particular location of the mobile machine 102 in relation to the zones of
Petition 870180003542, of 01/15/2018, p. 88/126 / 40 impact on production, or sensitive areas 184, and based on the avoidable compaction areas identified by the production impact map 128. This is indicated by block 316 in the flowchart of figure 4.
[0059] The alarm signal generation logic / other UI 204 can generate alerts in near real time or other interfaces for operator 104, for operators of support vehicles, for a front manager, or for other people or systems. This is indicated by block 318.
[0060] Control signals can be generated for use by remote systems 106. Therefore, for example, an alert control signal can be generated and communicated using communication system 126 to a remote system 106 to alert a user in the remote system 106 that an operator 104 is frequently driven over sensitive areas 184, or to alert them to a wide variety of other things. This is just one example of how control signals can be generated and communicated to remote systems 106. This is indicated by block 320 in the flowchart of figure 4.
[0061] The control signal generator 132 can also generate a wide variety of other control signals. This is indicated by block 322 in the flowchart of figure 4.
[0062] Figure 5 is a more detailed block diagram showing an example of a remote system 106. It will be recognized that a wide variety of other remote systems can also be used, and that shown in Figure 5 is shown for example only. In the example shown in figure 5, remote system 106 illustratively includes one or more processors or servers 340, communication system 342, database 344, post-harvest recommendation engine 346, replanting decision engine 348 , user interface logic 350, and can include a wide variety of other items 352. Communication system 342 can be similar to communication system 126, or different. On a
Petition 870180003542, of 01/15/2018, p. 89/126 / 40 example, it is configured to communicate over the network 108 with the mobile machine 102. Thus, it can receive the control signals, the pass map 170, the surface / soil moisture metric 172, the various soil compaction stress maps, production maps, etc. generated by the mobile machine 102.
[0063] The post-harvest recommendation engine 346 can include the front-end equipment deployment logic 354, the financial computing logic 356, and can include a wide variety of other items 358. The front-end equipment deployment logic 354 can be used to generate 360 post-harvest recommendations that indicate how the equipment could be developed differently on the various fronts during harvest, in order to reduce the impact of soil compaction on production. This may include, for example, changing the path of the combine or support machines, changing the types of the machines or characteristics of the machines, changing the configuration of the machines (such as reducing the number of wagons pulled by a given tractor, change in tire pressure, etc.).
[0064] The financial computation logic 356 can estimate a financial value corresponding to changes in production, due to soil compaction. For example, it can generate a value indicative of an estimated increase in cost, due to lost production, for a particular front configuration. It can also generate this same metric for a different front configuration, so that a user can quantify changes in production, for the two different front configurations. The user can thus make better decisions on how to deploy equipment on a given front, in order to obtain additional efficiencies.
[0065] The replanting decision engine 348 illustratively generates replanting recommendations 362 that can be indicative of when a crop should be replanted. For example, compacting the subsoil (for example, compacting the soil to a depth in excess of 60 cm)
Petition 870180003542, of 01/15/2018, p. 90/126 / 40 in a sugarcane field can accumulate over different years. The compaction of the subsoil simply continues to increase in an aggregate manner, from year to year, unless it is slowed down by frost or otherwise. This can affect the growth of roots, and can also affect the amount of moisture and nutrients that reach the roots, which can affect production. Similarly, the topsoil compaction stress can also accumulate over a given season, or multiple seasons, to affect production as well. The replanting decision engine 348 thus considers soil compaction as a factor in generating replanting recommendations 362. Other entries may include a current year after planting, expected years of harvest (given a variety of harvest, for example), replanting cost, the cost of lost production over the years remaining before replanting, among others. It can, for example, balance the cost of a reduction in production due to soil compaction over a number of years (and possibly other factors) against the cost of replanting. It will be recognized that remote system 106 can also generate a wide variety of other outputs 364.
[0066] This discussion mentioned processors and servers.
In one example, processors and servers include computer processors with associated memory and timing circuits, not shown separately. They are functional parts of the systems or devices to which they belong and are activated by, and facilitate the functionality of the other components or items in those systems.
[0067] Also, a number of user interface views have been discussed. They can take on a wide variety of different forms and can have a wide variety of different user-actionable input mechanisms arranged therein. For example, the input mechanisms that can be used by users can be text boxes, check boxes, icons, links, drop-down menus, search boxes, etc. They can also be
Petition 870180003542, of 01/15/2018, p. 91/126 / 40 performed in a wide variety of different ways. For example, they can be actuated using a point and click device (such as a "moving sphere" or a "mouse"). They can be operated using hardware buttons, switches, a control lever or keypad, thumb switches or thumb pads, etc. They can also be operated using a virtual keyboard or other virtual actuators. In addition, when the screen on which they are displayed is a touch screen, they can be actuated using touch gestures. Also, when the device displaying them has speech recognition components, they can be activated using voice commands.
[0068] A number of databases have also been discussed. It will be noted that they can each be broken down into multiple databases. Everyone can be local to the systems that access them, everyone can be remote, or some can be local while others are remote. All of these configurations are covered here.
[0069] Also, the figures show a number of blocks with functionality assigned to each block. It will be noticed that fewer blocks can be used, so the functionality is performed by fewer components. Also, more blocks can be used with the functionality distributed among more components.
[0070] It will also be noted that the information on map 107 can be provided to the cloud.
[0071] Figure 6 is a block diagram of the mobile machine 102, shown in figure 1, except that it communicates with elements in a remote server architecture 500. In one example, the remote server architecture 500 can provide computing, software, data access, and storage services that do not require the end user's knowledge of the physical location or configuration of the system providing the services. In several ways, remote servers can provide services over a range of
Petition 870180003542, of 01/15/2018, p. 92/126 / 40 wide area network, such as the Internet, using appropriate protocols. For example, remote servers can deliver applications over a wide area network and they can be accessed through a web browser or any other computing component. Software or components shown in figure 1 as well as the corresponding data can be stored on the servers in a remote location. The computing resources in a remote server environment can be consolidated into a remote data center location or they can be dispersed. Remote server infrastructures can provide services through a shared data center, even if they appear as a single access point for the user. Thus, the components and functions described here can be provided from a remote server at a remote location using a remote server architecture. Alternatively, they can be provided from a conventional server, or they can be installed on client devices directly, or in other ways.
[0072] In the example shown in figure 6, some items are similar to those shown in figure 1 and are similarly listed. Figure 6 specifically shows that remote systems 106 can be located on a local remote server 502. Therefore, mobile machine 102 accesses those systems via remote server location 502.
[0073] Figure 6 also represents another example of a remote server architecture. Figure 6 shows that it is also contemplated that some elements of figure 1 are arranged in the remote server location 502 while others are not. For example, database 120 or mapping system 128 can be arranged at the remote server location 502 or at a location separate from location 502, and accessed via the remote server at location 502. Regardless of where they are located , they can be accessed directly by the mobile machine 102, via a network (either a wide area network or a local area network), they can be accessed
Petition 870180003542, of 01/15/2018, p. 93/126 / 40 hosted at a remote location by a service, or they can be provided as a service, or accessed by a connection service that is located at a remote location. Also, data can be stored in substantially any location and intermittently accessed by, or transmitted to, interested parties. For example, physical carriers can be used in place of, or in addition to, magnetic wave carriers. In such an example, where cell coverage is poor or non-existent, another mobile machine (such as a fuel truck) may have an automated information collection system. When machine 102 approaches the fuel truck for refueling, the system automatically collects information from machine 102 using any type of wireless connection for this purpose. The collected information can then be transmitted to the main network when the fuel truck arrives at a location where cell coverage (or other wireless coverage) exists. For example, the fuel truck can feed a covered location when moving to fuel other machines or when at a primary fuel storage location. All of these architectures are covered here. In addition, the information can be stored on machine 102 until machine 102 enters a covered location. Machine 102, itself, can then send the information to the main network.
[0074] It will also be noted that the elements of Figure 1, or portions thereof, can be arranged in a wide variety of different devices. Some of those devices include servers, desktop computers, portable computers, tablet computers, or other mobile devices, such as pocket computers, cell phones, smart phones, multimedia players, personal digital assistants, etc.
[0075] Figure 7 is a simplified block diagram of a
Petition 870180003542, of 01/15/2018, p. 94/126 / 40 illustrative example of a portable or mobile computing device that can be used as a user or customer portable device 16, in which the present system (or parts thereof) can be deployed. For example, a mobile device can be deployed in an operator's compartment of the mobile machine 102 for use in generating, processing, or displaying the various data and / or alerts, etc. Figures 8 and 9 are examples of portable mobile devices.
[0076] Figure 7 provides a general block diagram of the components of a client device 16 that can run some components shown in Figure 1, which interact with them, or both. In device 16, a communications link 13 is provided, which allows the portable device to communicate with other computing devices and, in some embodiments, provides a channel for receiving information automatically, such as by digitization. Examples of communications link 13 include allowing communication through one or more communication protocols, such as wireless services used to provide cellular access to the network, as well as protocols that provide local wireless connections to networks.
[0077] In other examples, applications can be received on a removable Secure Digital (SD) card, which is connected to an interface 15. Interface 15 and communication links 13 communicate with a processor 17 (which can also incorporate processors or servers 116 or 340 of the previous figures) along a bus 19 which is also connected to memory 21 and input / output (I / O) components 23, as well as clock 25 and local system 27.
[0078] The I / O components 23, in one modality, are provided to facilitate the input and output operations. I / O components 23 for various modes of device 16 may include input components, such as buttons, touch sensors, optical sensors, microphones, screens
Petition 870180003542, of 01/15/2018, p. 95/126 / 40 touch sensitive, proximity sensors, accelerometers, orientation sensors, and output components, such as a display device, a speaker, and or a printer logic port. Other I / O components 23 can also be used.
[0079] Clock 25 illustratively comprises a real time clock component that provides the time and date. It can also provide, illustratively, timing functions for processor 17.
[0080] The local system 27 illustratively includes a component that provides a current geographic location of the device 16. This may include, for example, a global positioning system (GPS) receiver, a LORAN system, a passive recognition system, a cell triangulation system, or other positioning system. It can also include, for example, mapping software or navigation software that generates the desired navigation routes and other geographic functions.
[0081] Memory 21 stores operating system 29, network settings 31, applications 33, application configuration settings 35, database 37, communication controllers 39, and communication configuration settings 41. Memory 21 it can include all types of computer readable volatile and non-volatile tangible memory devices. It can also include computer storage media (described below). Memory 21 stores computer-readable instructions that, when executed by processor 17, cause the processor to perform the steps or functions implemented by computer according to the instructions. Processor 17 can also be activated by other components to facilitate its functionality.
[0082] Figure 8 shows an example in which device 16 is a 600 tablet computer. In figure 8, computer 600 is shown with the user interface display screen 602. Screen 602 can be a touch sensitive screen. touch or a pen operated interface that receives inputs from
Petition 870180003542, of 01/15/2018, p. 96/126 / 40 from a pen or needle. He can also use a virtual keyboard on the screen. Of course, it could also be attached to a keyboard or other user input device via an appropriate display mechanism, such as a wireless connection or USB logical port, for example. The computer 600 can also illustratively receive voice inputs.
[0083] Figure 9 shows that the device can be a smart phone 71. The smart phone 71 has a touch sensitive display 73 that displays icons or tiles or other user input mechanisms 75. The mechanisms 75 can be used by a user to run applications, make calls, perform data transfer operations, etc. In general, the 71 smart phone is integrated into a mobile operating system and offers more advanced computing and connectivity capabilities than a conventional phone.
[0084] Note that other forms of devices 16 are possible.
[0085] Figure 10 is an example of a computing environment in which the elements of Figure 1, or parts thereof, (for example), can be developed with reference to Figure 10, an example system to implement some modalities includes a general purpose computing device in the form of a computer 810. Computer components 810 may include, but are not limited to, an 820 processing unit (which may comprise 116 or 340 processors or servers), an 830 system memory , and a system bus 821 that couples various system components including system memory to the 820 processing unit. The system bus 821 can be any of several types of bus structures including a memory bus or a memory controller, a peripheral bus, and a local bus using any of a variety of bus architectures. The memory and programs described in relation to the previous figures can be
Petition 870180003542, of 01/15/2018, p. 97/126 / 40 implanted in the corresponding portions of figure 10.
[0086] The 810 computer typically includes a variety of computer-readable media. Computer-readable media can be any available media that can be accessed by computer 810 and includes both volatile and non-volatile media, removable and non-removable media. For example, and not by way of limitation, computer-readable media may comprise computer storage media and communication media. The computer storage medium is different from, and does not include, a modulated data signal or carrier wave. It includes hardware storage media including removable and non-removable media, both volatile and non-volatile, implemented in any method or technology for storing information, such as computer-readable instructions, data structures, program modules or other data. Computer storage media includes, but is not limited to, RAM, ROM, EEPROM, USB memory or other memory technology, CD-ROM, digital versatile discs (DVD) or other optical disc storage, magnetic tapes, magnetic tape , storage by magnetic disk or other magnetic storage devices, or any other medium that can be used to store the desired information and that can be accessed by a computer 810. The communication medium may incorporate computer-readable instructions, data structures, modules program or other data in a transport mechanism and includes any means of providing information. The term "modulated data signal" means a signal that has one or more of its characteristics adjusted or altered in such a way as to encode information in the signal.
[0087] System memory 830 includes computer storage media in the form of volatile and / or non-volatile memory, such as read-only memory (ROM) 831 and random access memory
Petition 870180003542, of 01/15/2018, p. 98/126 / 40 (RAM) 832. A basic 833 input / output system (BIOS), containing basic routines that help transfer information between elements within the 810 computer, such as during startup, is typically stored in ROM 831 RAM 832 typically contains data and / or program modules that are immediately accessible to, and / or are currently operated on, processing unit 820. As an example, and not a limitation, figure 10 illustrates the 834 operating system , application programs 835, other program modules 836, and program data 837. [0088] Computer 810 may also include other volatile / non-volatile, removable / non-removable computer storage media. For example only, Figure 10 illustrates the hard disk drive 841 that reads from, or inscribes on, non-removable, non-volatile magnetic media, an optical disk drive 855, and non-volatile optical disk 856. The drive Hard disk drive 841 is typically connected to the system bus 821 via a non-removable memory interface, such as the 840 interface, and optical disk drives 855 are typically connected to the system bus 821 by a removable memory interface, such as like the 850 interface.
[0089] Alternatively, or in addition, the functionality described here can be performed, at least in part, by one or more hardware logic components. For example, and without limitation, illustrative types of hardware logic components that can be used include Programmable Logic Gate Networks (FPGAs), application specific integrated circuits (eg ASICs), standardized products for specific application (eg ASSPs), integrated chip systems (SOCs), complex programmable logic devices (CPLDs), etc.
[0090] The controllers and their associated computer storage media, discussed above and illustrated in figure 10, provide the storage of computer-readable instructions, data structures,
Petition 870180003542, of 01/15/2018, p. 99/126 / 40 program modules and other data for computer 810. In Figure 10, for example, hard drive 841 is illustrated as storing the 844 operating system, 845 application programs, other 846 program modules, and program data 847. Note that these components can be either the same or different from the operating system 834, application programs 835, other program modules 836, and program data 837. [0091] A user can feed commands and information to the computer 810 via input devices, such as a keyboard 862, a microphone 863, and a pointing device 861, such as a "mouse", "moving sphere" or touch pad. Other input devices (not shown) may include a control stick, game pad, satellite dish, digitizer, or the like. These and other input devices are often connected to the processing unit 820 via an 860 memory input interface that is coupled to the system bus, but can be connected by other interfaces and bus structures. A visual display 891 or other type of display device is also connected to the system bus 821 via an interface, such as an 890 video interface. In addition to the monitor, computers may also include other peripheral output devices, such as 897 speakers and 896 printer, which can be connected via an 895 output peripheral interface.
[0092] The 810 computer is operated in a network environment using logical connections (such as a local area network - LAN, or wide area network WAN) to one or more remote computers, such as a remote 880 computer.
[0093] When used in a LAN networked environment, the 810 computer is connected to LAN 871 via a networked interface or 870 adapter. When used in a WAN networked environment, the 810 computer includes typically an 872 modem
Petition 870180003542, of 01/15/2018, p. 100/126 / 40 or other means to establish communications over the WAN 873, such as the Internet. In a networked environment, program modules can be stored on a remote memory storage device. Figure 10 illustrates, for example, that remote application programs 885 may be on remote computer 880.
[0094] It should also be noted that the different modalities described here can be combined in different ways. That is, parts of one or more modalities can be combined with parts of one or more other modalities. All of this is covered here.
[0095] Example 1 is a mobile machine that moves over a workplace, the mobile machine comprising:
a mapping system that generates a compaction stress map indicative of soil compaction of soil through the workplace;
a workplace impact determination system that identifies, as a compaction impact, an impact of soil compaction in the workplace on a characteristic of the workplace, based on the compaction stress map; and a control signal generator that generates a control signal to control a controlled system, in real time, based on the compression impact.
[0096] Example 2 is a mobile machine according to any or all of the previous examples further comprising:
a sensitive area identifier that identifies, as sensitive areas of the workplace, areas in which the characteristic of the workplace is relatively more sensitive to soil compaction than in other areas of the workplace.
