[0001] The present invention relates to a watering installation and a control method and / or irrigation control. It is known to have a watering installation comprising at least one watering conduit for delivering a watering liquid such as water or a nutrient solution, especially for watering one or more plants. Such a watering installation can be associated with a scheduler so as to carry out watering automatically and selectively over predefined time periods. These provisions are satisfactory in that they make it possible to adapt the delivery of a quantity of water according to a predefined program. However, it appears that such a type of installation does not take into account the variability of environmental conditions, especially in the case of watering plants. The present invention aims to solve all or some of the disadvantages mentioned above. For this purpose, the present invention relates to a watering installation comprising: a controlled valve arranged to control the delivery of a watering liquid such as water or a nutrient solution by at least one watering pipe; At least one measurement sensor arranged to provide measurement data of at least one physical quantity representative of the environment; An electronic control unit arranged to determine a watering control according to the measurement data of at least one physical quantity representative of the environment provided by the at least one measurement sensor, the controlled valve being arranged to apply the irrigation control determined by the electronic control unit so as to control the delivery of the irrigation liquid. Thanks to the arrangements according to the invention, the electronic control unit is arranged to determine, on the basis of the measurement data communicated by the at least one sensor, a watering control adapted to the environmental conditions. By watering control is meant in particular a definition of a value or a time evolution of a desired value for a control variable corresponding for example to a desired flow rate in the at least one watering pipe or an opening / closing section of the at least one watering conduit defined by the valve. It is also possible to define a watering command as an order or a set of open / close commands communicated to the controlled valve, and in particular to an actuator, to obtain a desired value of said control quantity. According to one aspect of the invention, the at least one sensor comprises a soil moisture sensor. In particular, the sensor can determine the humidity by measuring the resistance across a "fork" intended to be buried in the ground. According to one aspect of the invention, the at least one sensor comprises a temperature sensor. The temperature measured is in particular the temperature of the ambient air. According to one aspect of the invention, the at least one sensor comprises a sun sensor. This sensor can also be used to detect day / night alternations. These arrangements allow for example the electronic unit to determine that a watering is not desirable at noon in full sun, while a watering can be triggered when the detection of the night or later 20 in the night. According to one aspect of the invention, in a case where the watering command is defined as an order or a set of open / close commands, a watering control message comprises at least one action order of start and end order of watering. Thanks to these arrangements, it is possible to avoid a risk of non-receipt of a closing order of the valve. According to one aspect of the invention, the determination of the watering control comprises a use of at least one control profile comprising several distinct phases. A control profile can in particular correspond to a model for defining a time evolution of a desired value for a control quantity, for example a flow rate, the distinct phases thus being able to correspond to distinct levels of flow. In particular, the predefined control profile may correspond to a profile adapted to a type of plant to be watered, or to a profile of time evolution of the irrigation control. According to one aspect of the invention, the installation is arranged to adapt measurement intervals of the sensor. According to one aspect of the invention, the adaptation of the measurement intervals can be performed as a function of communication intervals with the electronic control unit or as a function of the variation or the relevance of the measurement values. For example, the measurement interval can be changed if variations of a determined amplitude are detected. In another example, the measurement interval can be reduced over a period of communication with the electronic control unit. These provisions make it possible to reduce the energy consumption of the installation. According to one aspect of the invention, the at least one control profile can be parameterized, in particular according to the data collected. According to one aspect of the invention, the sensor and / or the solenoid valve comprise a photovoltaic module intended to produce the energy required for its operation and / or the charge of a battery included in the sensor or solenoid valve. In the same way the electronic control unit can comprise a photovoltaic module. These arrangements make it possible to ensure the power supply of the sensor and / or the solenoid valve and / or the electronic control unit. According to one aspect of the invention, the sensor is arranged to differentiate environmental conditions corresponding to a brightness level of a time covered by a temporary brightness decrease corresponding for example to the passage of a cloud.

These arrangements make it possible to use the controlled valve to serve two watering zones from a watering liquid supply. According to one aspect of the invention, the sprinkler installation comprises at least one flow sensor arranged to provide measurement data of a flow of cooling liquid in the at least one watering conduit. These provisions allow the electronic unit to control the watering by defining a watering rate to be delivered to the plants. Moreover, the delivered volume can also be accurately determined. These provisions 15 make it possible to achieve more precise watering than watering defined by a watering time. The coolant flow sensor can be integrated into the controlled valve or inserted into another part of the installation. According to one aspect of the invention, the electronic unit is arranged to trigger a switching of the controlled valve according to a value representative of low flow rate communicated by the watering liquid flow rate sensor to another source of supply, in the case where the controlled valve is a valve with at least three channels. For example, it is possible to preferentially switch the valve controlled on a rainwater reserve, and then to switch the valve on the drinking water supply network when a too low flow is detected by the sensor. debit. According to one aspect of the invention, the electronic control unit is arranged to perform a periodic check of the filling of the water reserve. In case of low rate detection (thus low level of the reserve), it may be chosen to simply alert the user by an alert message, for example via a mobile terminal such as a smartphone.

According to another aspect of the invention, a flow sensor is arranged upstream of the solenoid valve. According to one aspect of the invention, the electronic control unit is arranged to compare the measurement data of a flow of coolant supplied by the at least one flow sensor to the irrigation control determined in function of the measurement data of at least one physical quantity representative of the environment. Thanks to these arrangements, the electronic control unit can perform a servo-control according to a desired flow rate. According to one aspect of the invention, the electronic control unit is arranged to perform an automatic diagnosis of the controlled valve. Thus, the electronic unit can determine the presence of a leak if a significant value of flow is detected while the control of the controlled valve corresponds to a closed state.

According to yet another embodiment of the invention, the electronic unit 30 is distant from both the at least one sensor and the controlled valve. According to one aspect of the invention, the communication interface of the electronic unit, the at least one first measurement sensor and / or the at least one second measurement sensor are type 35 communication interfaces. radio frequency.
[0003] According to one aspect of the invention, the installation comprises a first electronic control unit and a second electronic control unit, the first electronic control unit and the second electronic control unit being arranged to communicate so as to allow the one of the two electronic control units is identified as a master unit and defines the watering control. These arrangements make it possible in particular to have an electronic control unit in the sensor or the solenoid valve to carry out a command when the installation does not include a second electronic control unit constituted for example by a control entity of a home automation system. , or that this second unit is not in operation or not accessible by means of communication. According to one aspect of the invention, the controlled valve is arranged to deliver a sprinkling rate proportional to a value of the sprinkler control 15 provided by the electronic control unit. These arrangements make it possible to control the controlled valve according to a desired flow rate, and not in all-or-nothing. It is thus possible to perform watering "drip" or "high flow" by controlling the flow and the total volume delivered. According to one aspect of the invention, the electronic control unit is arranged to collect meteorological data and to determine the watering control also according to said meteorological data. According to these provisions, the electronic control unit can take into account in the determination of the irrigation control meteorological data which have an influence on the water requirements of the plants to be watered. According to one embodiment, the electronic unit is arranged to collect programming data entered or selected by a user and to determine the watering control also according to the programming data. According to one aspect of the invention, the watering installation comprises a user interface system arranged to collect programming data to be filled in and / or selected by a user. The interface system may in particular comprise a screen and command buttons, or a touch screen, or an application hosted on a mobile terminal, or a web page accessible by a private or public network.

According to another aspect of the invention, a specific remote control may be provided to directly control the solenoid valve and / or the sensor. Based on the measurement data of the different sensors, meteorological data, and user programming, the electronic unit can optimize a watering scenario. For example, the electronic unit can cancel a watering cycle if a rainy day is forecast the next day by the meteorological data. According to one aspect of the invention, the electronic unit is arranged to access a data repository relating to types of plants to be watered, including data on the type of watering to be applied to said plants, so as to propose or carry out the determination of a choice of watering.

The distinct phases therefore correspond to waterings according to different flow rates or variations of different flow rates. These arrangements make it possible to prepare / humidify the soil during the first phase with a low flow rate in order to avoid runoff during the second phase, then to proceed with watering with a second higher flow rate during a second phase. By way of example, the end of the second phase can be determined by the observation of a satisfactory humidity level by a humidity probe.

[0014] During the implementation of the irrigation command by the controlled valve 2, 2 ', the electronic processing unit 15 of the valve controls the operation of the engine and consequently the degree of opening of the valve (s) closing the valves. valve channels. By controlling the angular position at the output of the engine, it thus controls the watering liquid circulation section and therefore the watering rate (for a given pressure). This flow can be verified by reading the measurement provided by the watering liquid flow sensor. The control method of a watering installation 1 will now be described with reference to FIG. 2. The control method may comprise an initial learning step EO during which a correlation of the programming data DP and data for measuring at least one physical quantity representative of the environment DR is carried out so as to determine DA training data. For example, a learning step during a period of use, including an initial usage time, for example a few days, can be achieved by correlating programming data that reflects the habits of the client user and the data. measuring at least one physical quantity representative of the environment, such as in particular soil moisture, temperature or sunshine. In particular, the speed of absorption of the watering liquid by the soil can be learned (thanks to a correlation between the watering or rainfall data and the data provided by the soil moisture sensor). This speed information can be used to set a maximum watering rate. The training data DA may be used later to determine a watering command Cmd. Following the initial EO learning step if it is performed, one or more data collection steps described above can be performed, and in particular: El: A step of collecting measurement data of at least one magnitude physical representative of the DR environment; E12 a step of collecting data for measuring a flow rate of spraying liquid DD obtained by a measurement in the watering pipe 19, E13 a step of collecting meteorological data DM, E14 a step of collecting programming data DP filled in or selected by a user. It should be noted that reference data on DV plants can also be collected as we have seen previously. On the basis of the data collected, a step E2 for determining a watering command Cmd is carried out. The determination of the watering command E2 may comprise a use of at least one profile or control scenario Pr predefined, in particular configurable, providing one or more distinct phases. In particular, the control profile Pr may correspond to a profile adapted to a type of plant to be watered, or even to a temporal evolution profile of the watering control. These provisions make it possible to optimize a watering scenario in order to minimize water consumption while optimizing the humidity level of the land over the long term. According to a first example shown in FIG. 9, a control profile Pr comprises at least a first watering phase at a first flow value D1 during a first watering period p1, then a second watering phase at a first watering stage p1. second flow rate value D2 greater than D1 during a second watering period p2. Thus, it is possible to prepare / humidify the soil during the first phase with a low flow rate in order to prevent runoff of the coolant and then to water with a second, higher flow rate during the second phase. The end of the second phase can be determined by the observation of a satisfactory humidity level on the basis of the data provided by the humidity sensor 3a or by the expiry of a time delay. In another example, the control profile Pr can be defined by determining the flow rate of the cooling liquid as a function of the humidity variation noted at the probe over a period of time. The period of time may be set before a watering period, and / or during a watering period, or following a watering period. In another example, the control profile Pr over a few days can be defined by following "wet-dry land" cycles, these cycles possibly being necessary for the proper development of the roots of certain plants.
[0015] In another example, the control profile Pr can incorporate rationing watering. This rationing may be based on information relating to a drought period, provided to the electronic control unit or defined from the water level reduction information of a rainwater recovery tank. The water level in the rainwater recovery tank can be estimated in particular from a flow variation measured by the flow sensor of the controlled valve. According to another example, the control profile Pr can make it possible to manage two (or even three) different zones with water spray sprinklers from a nozzle connected at the end of the watering duct. In this case, the control profile incorporates variations in water flow: with a low flow, it is possible to water near the nozzle, with a high flow, watering is carried out a few meters later in a second zoned. The control profile can define a triggering of the watering preferentially in the first hours, especially the first three hours or the first two hours, after sunrise and / or the last hours including the last three hours or both. last hours before sunset. The detection of day and night can be achieved in particular by the sun sensor. The electronic control unit may also include a clock to allow time programming which may also perform this detection. The control profile or scenario may correspond to the definition of a flow or water volume constraint as a function of time. The command can be performed on a time and / or flow and / or volume criterion. The control method may comprise a step of verifying at least one safety criterion on the volume or the watering time by providing a stopping threshold beyond a duration of watering or a volume. maximum watering. Finally, a watering step E3 is carried out during which delivery of a cooling liquid is carried out in correspondence with the watering control Cmd. The control method may also comprise a step of comparing the measurement data of a flow of cooling liquid obtained by a measurement with the irrigation control, in particular to check the correspondence between the flow rate of the delivered watering liquid and the expected watering command. This comparison makes it possible to perform a servo-control according to a desired flow rate by a regulation loop which makes it possible to obtain a more precise control of the watering. This comparison also allows or alternatively to perform an automatic diagnosis of the controlled valve. Thus, the electronic unit can determine the presence of a leak if a significant value of flow is detected while the command of the controlled valve corresponds to a closed state. The method may also include a step of selecting a sprinkler supply source from a plurality of sprinkler supply sources 9, 10, the amount of sprinkler liquid delivered at the watering step E3 being taken from the selected power source.
[0016] Thus, it is possible to trigger a switching of the controlled valve according to a representative value of low flow rate communicated by the coolant flow sensor 5 to another power source, in the case where the valve controlled is a three-way valve. Thus, by way of example, in the embodiment of an installation such as described in FIG. 1, it is possible to preferentially switch the valve controlled on a rainwater reserve, then to switch the valve on the network. supply of drinking water when a too low flow rate is detected by the flow sensor 5. It is also possible to perform a periodic check of the filling of the water supply 9. As is obvious, the invention is not limited to the sole embodiment of this device and control system and / or control, described above by way of example, it encompasses all the variants. In the present application, the term watering covers the watering of soils and plants, but also the management of the delivery of water in the context of home automation applications, inside or outside a building , in particular for the management of supply of one or more water jet, the filling of one or more water basins, the management of one or more foggers, in particular terrace foggers.
