    TECHNICAL FIELD The present invention relates to a method for controlling the propulsion of a drilling rig. The invention also relates to a computer program product comprising program code for a computer for implementing a method according to the invention. The invention also relates to a system for controlling the propulsion of a drilling rig and a drilling rig which is equipped with such a system.
    BACKGROUND Wag there are a number of different platforms with caterpillar feet available for different applications.
    A drilling rig can be an example of such a platform with caterpillar feet. Said drilling rig may, for example, be arranged for use above ground. In this case, the drilling rig can be arranged to perform various types of construction work.
    The said platforms may be operator-controlled, i.e. a driver can control the progress and operation of, for example, tools or machines on the platform from a driver's cab. Alternatively, said platforms may be radio-controlled scar-controlled.
    Said platform can be arranged to be controlled by means of so-called band control. These platform shapes can be propelled with crawler tracks or wheels. In this case, a respective speed of a belt on a first side and a second belt on a second side can be manually controlled by means of suitable electronic or mechanical actuators, for example a steering wheel and an accelerator pedal. The platform can thus be made to swing by applying different speeds of said first belt and said second belt. During propulsion of the platform, including arches, malfunctions may occur. In particular, these irregularities occur in the event of changes in direction when propulsion takes place on a bare, muddy or sandy surface where rather large forces are applied by means of the caterpillar feet to rotate the platform about an axis of rotation thereof. 2 These inconveniences may partly refer to the responsible handling of the platform where a driver has to shoot a change in a transmission at the platform at the same time as he has to keep an eye on things propelling. Furthermore, in some cases the driver must also consider supported equipment, such as, for example, drilling devices, when propelling said platform. Propulsion of a platform with two caterpillar feet can be perceived as complex by a driver, especially when cornering, since a number of work steps need to be performed simultaneously or substantially simultaneously.
    These irregularities may partly refer to undesirable changes in the operating condition of the platform. These changes of operating state may refer to undesired reduction of a radiating speed of a motor of the platform due to increased load arising from said changes of direction. Unwanted engine stops can occur. In some situations, the caterpillar tracks can stop if an increased load on the platform becomes too large.
    US 7,290,390 B2 describes a control device for a hydraulic excavator of the crawler type where slow start is possible with manual control thereof.
    SUMMARY OF THE INVENTION There is thus a need to handle control of a platform with two crawler tracks in a reliable, user-friendly and robust manner for propelling the platform.
    An object of the present invention is to provide a new and advantageous method for controlling the propulsion of a drilling rig.
    Another object of the invention is to provide a new and advantageous system for controlling the propulsion of a drilling rig and a new and advantageous computer program for controlling the propulsion of a drilling rig.
    A further object of the invention is to provide an alternative method, an alternative system and an alternative computer program for controlling the propulsion of a drilling rig. A further object of the invention is to provide a user-friendly method for effecting an operational propulsion of a drilling rig, where the risk of engine stoppage and / or stopping of crawler tracks during propulsion is reduced.
    A further object of the invention is to provide a method, a system, and a computer program for improving the performance of a drilling rig of so-called crawler type.
    Some of said objects are achieved with a method for controlling the propulsion of a drilling rig according to claim 1. Other objects are achieved with a system for controlling the propulsion of a drilling rig according to claim 9. Advantageous embodiments are stated in the dependent claims.

    This provides a reliable and user-friendly method for controlling the propulsion of a drilling rig. When cornering with said drilling rig, a suitable, lower, gearing condition can be determined in order to enable automatic downshifting of a transmission of the drilling rig. In this way, an operator can be relieved and thereby obtain better conditions for paying attention to moving or fixed objects or persons in the vicinity of the drilling rig. In this case, the drilling rig can be advanced in a safer manner.

    According to an example, a suitable gearing state can be the nearest lower gearing state compared to a radiating gearing state. In the event that a radiating gear state is, for example, a third gear state and it is determined that a lowering to a second gear state is required, the said second gear state is referred to as a suitable gear state.

In the event that a radiating gear state is, for example, a third gear state and it is determined that a lowering to a first gear state is required, then said first gear state is called a suitable gear state. Depending on a magnitude of said difference between the requested drive speed of said right and left propulsion means, a number of steps for a gear state change can be determined. In this case, a new gear state is determined, to which a change must take place relative to a radiating gear state on the basis of the difference thus established. Said new gearing stage / gearing state can be called an appropriate gearing stage gearing state.

By calculating / determining / nodeling appropriately lower gear state of the drilling rig's transmission, the drilling rig can be propelled during substantially optimal operation, including fuel consumption and generated driving torque of the drilling rig's propulsion means.
    The method may comprise the step of: 6th nan the difference in the required driving speed of said right and left propulsion means with a predetermined threshold value, wherein the lumbar gear state is determined when said difference exceeds said threshold value. This provides a time-efficient and robust way of activating / performing, for example, a change of gearing state of the drilling rig transmission. Advantageously, undesired change of gear condition will be prevented by the said comparison. This provides a cost-effective way of achieving operational reliability, operator comfort and reduced wear of components of the drilling rig, for example a gearbox.
    The method may comprise the step of: determining the required driving speed for said right and left propulsion means, the said difference being determined only when at least one requested driving speed exceeds a predetermined threshold value.
    This provides a robust way of avoiding undesired activation of, for example, a change in gearing state of the drilling rig transmission. Advantageously, an undesired change of gear state will be prevented by considering the said fixed requested driving speeds. This provides a cost-effective way to provide operational reliability, operator comfort and reduced wear of components of the drilling rig, for example a gearbox.

    DETAILED DESCRIPTION OF THE FIGURES Referring to Figure 1a, there is shown a side view of a drilling rig 100 which may be used for various types of earthworks and / or construction works and in which the present invention may be used. The drilling rig 100 can be adapted for mining. The drilling rig can be adapted for above-ground mining. In this case, the drilling rig 100 can be adapted to perform so-called striking drilling.
    According to an example pile design, the drilling rig 100 is adapted for operation in open quarries.
    According to an exemplary embodiment, the drilling rig 100 is adapted for use in infrastructure work. The drilling rig 100 can be of any suitable lamp size and have a mass within a range of, for example, 3-30 tonnes (3,000-30,000 kg).
    Said drilling rig 100 comprises, among other things, an elongate, movable arm 110 in one end of which a drilling device 120 is arranged, caterpillar feet 130 for propelling the rig 100, a driver's cab 140 for an operator and an engine body 150. Said movable arm 110 may also be called a folding boom.
    Said motor body 150 houses several different components saint system for said drilling rig 100 to function satisfactorily, such as a motor 2 which is arranged to supply the required power to said drilling rig 100. Said motor 230 is thus used, for example, to propel said drilling rig 100. movement of said elongate arm 110 and to drive said drill bit 120. According to an alternative embodiment, said motor 230 is used to propel said drill rig 100, a separate power unit (not shown) being used to drive said elongate arm 110 and said drill bit 120. In this case, a unit consisting of said engine body 150, said driver's cab 140 and caterpillar feet 130 can be called carriers.
    Said engine body 150 may also comprise a suitable transmission (not shown) for power transmission from said engine 230 and said caterpillar feet 130. Said transmission may be, for example, an electronically controlled mechanical transmission. According to an exemplary embodiment, said transmission is a hydraulic transmission.
    Herein the term "lank" refers to a communication link which may be a physical line, such as an opto-electronic communication line, or a non-physical line, such as a wireless connection, for example a radio or microcarriage line.
    In this he uses the term "line" to a passage for holding and transporting a fluid, such as e.g. a hydraulic oil. The pipe can be a rudder of any dimension.
    The line can consist of an arbitrary, land-based material, such as e.g. plastic, rubber or metal.
    It should be noted that the invention is suitable for application to any suitable vehicle or other platform and is thus not limited to systems of a drilling rig. The inventive method and the inventive system may be suitable for other platforms than drilling rigs which include a transmission and at least two crawler feet for propulsion, such as e.g. mining vehicles, tractors, dump trucks, vehicles / platforms for industrial robots, forestry machines, tracked vehicles, construction vehicles, commercial vehicles, off-road vehicles or combat vehicles.
    The term "lamplig" is used inter alia in the sense of "arbitrary lamplig" or "relevant according to one aspect of the invention".
    Referring to Figure 1b, said drilling rig 100 is shown in a view above.
    Said caterpillar feet 130, which are illustrated in Figure 1, are illustrated in further detail. Said caterpillar foot 130 includes a first propulsion means 130a and a second propulsion means 130b. This illustrates said first propulsion means 130a comprising a first belt. The said "first propulsion means 130a" is also referred to as the "left propulsion means 130a". Said first propulsion means 130a comprises at least one drive wheel (not shown) of said transmission for driving said second belt.
    This illustrates said second propulsion means 130b comprising a second belt. The said "second propulsion means 130b" is also referred to as the "right propulsion means 130b". Said second propulsion means 130b comprises at least one drive wheel (not shown) of said transmission for driving said second belt.
    The drilling rig 100 is arranged to be controlled by a so-called band control. In this case, a respective speed of said first propulsion means 130a and said second propulsion means 130b can be controlled mutually independently. The drilling rig 100 can thus be caused to pivot by applying different speeds of said first propulsion means 130a and said second propulsion means 130b. In this case, it should be noted that said first propulsion means 130a and said second propulsion means 130b may be designed in any suitable manner, for example with caterpillar feet and / or wheels. The important thing according to the present invention is that the drilling rig 100 can be made pivoted by the belt control principle, where speed control of said first propulsion means 130a and said second propulsion means 130b is used to control directional changes of the drilling rig 100.
    It is illustrated that said first propulsion means 130a has a first speed v1 and said second propulsion means 130b has a second speed v2. According to this example, v1 and v2 are substantially of equal size, the drilling rig being driven in a straight-ahead direction. The illustrated speeds v1 and v2 are illustrated. These required speeds v1 and v2 need not necessarily be equal to the actual speeds of said first propulsion means 130a and said second propulsion means 130b. For the sake of simplicity, it is assumed according to this example that the requested speeds are equal to the respective requested speeds.
    In a case where said first speed v1 exceeds said second speed v2, the drilling rig 100 can be caused to swing at Niger. Similarly, in a case where said first speed v1 is less than said second speed v2, the drilling rig 100 may be caused to turn to the left. The corresponding grid, of course, is for a reverse direction of the drilling rig 100. At this reverse direction, v1 and v2 have the opposite direction to the directions shown in Figure 1b. For a reverse direction of the drilling rig 100, v1 and v2 show negative signs.
    It should be noted that pivoting of the drilling rig 100 by means of belt guide can be performed by one of said first propulsion means 130a or said second propulsion means 130b standing still, the opposing propulsion means having a speed other than zero. Swinging of the drilling rig 100 by means of belt guide can be performed, for example, when v1 is equal to zero (said first propulsion means 130a is stationary), v2 being non-zero (said second propulsion means 130b is driven, in a forward or reverse direction).
    It should be noted that rotation of the drilling rig 100 about its own axis can be performed by belt control in that said first propulsion means 130a and said second propulsion means 130b have substantially equal zero-different speeds, which speeds are oppositely directed. Flarvid is thus v1 = -v2.
    Figure 2 schematically illustrates a subsystem 299 of said drilling rig 100, according to an aspect of the present invention.
    A first control unit 210 is provided for communication with a motor configuration 230 via a second line L230. The first control unit 210 is arranged to control the operation of said motor configuration 230. Said motor configuration 230 may comprise a lamp motor.

The first gear stage GS1 provides a lower gear ratio and provides a relatively slow maximum propulsion speed and a relatively strong propulsion. The second gear stage GS2 provides a higher gear ratio and provides a relatively high maximum propulsion speed and a relatively weak propulsion.
    Correspondingly, a transmission with a number of discrete gear stages can have a sequence of gear stages from a lowest gear ratio with the strongest propulsion to a highest gear ratio with the weakest propulsion. Said transmission may, for example, have 2, 3, 4, 5, 6, 10 or 12 discrete different gear stages. These discrete different gear stages are called hari gear state. The said transmission of said drilling rig 100 provides an output torque at a first drive unit 270a of said first propulsion means 130a and at a second drive unit 270b of said second propulsion means 130b. In this case, said first drive unit 270a and said second drive unit 270b are arranged to control the transmission of a driving torque to the first propulsion means 130a and the second propulsion means 230b, respectively. This can be done by controlling the first control unit 210. In this case, a speed of said first propulsion means 130a and the second propulsion means 130b can be controlled independently, wherein said drilling rig 100 has so-called skid steering 10 functionality. Said first drive unit 270a and said second drive unit 270b may be formed in any suitable manner.

    An operator can then use said paddles to drive the drilling rig 100's travel speed, both in terms of propulsion speed and changes of direction (by belt control).
    In this case, said first actuator 240 is arranged to continuously send a first signal including information on a requested speed v1 of said 18 first propulsion means 130a to the first control unit 210 via line L240. Then, said first actuator 240 is arranged to continuously send a second signal s2 including information about a requested speed v2 of said second propulsion means 130b to the first control unit 210 via the third line L240.
    According to an alternative, second, exemplary embodiment, said first actuator 240 comprises a first unit and a second unit. In this case, said first unit may comprise a knob or a joystick or other suitable device for controlling a propulsion direction of said drilling rig 100. In this case, said second unit may comprise a throttle control. According to an exemplary embodiment, said throttle control may comprise an accelerator pedal. In this case, said second unit can be used to request a throttle traction and thus a requested propulsion speed of said drilling rig 100. The first control unit 210 is then arranged to control propulsion of said drilling rig by controlling said transmission and said first drive unit 270a and said second drive unit 270b. in an appropriate manner.
    The first control unit 210 is arranged to continuously determine a requested speed v1 of said first propulsion means 130a and a requested speed v2 of said second propulsion means 130b, respectively. This can be done on the basis of signals received Than said first actuator 240. These signals may include information about a requested propulsion direction and requested propulsion speed of the drilling rig 100. The first control unit 210 is then arranged to determine corresponding speeds v1 and v2 for controlling the subsystem. 299 pa aptly put.
    According to one aspect of the present invention, a number of comparison steps are performed at the first control unit 210. In a first comparison step, it is determined whether said requested speed v1 of said first propulsion means 130a exceeds a first predetermined threshold value Th1.
    In this case, it is determined whether Iv11> Th1 19 In a second comparison step, it is determined whether said requested speed v2 of said second propulsion means 130b exceeds a second predetermined threshold value Th2.
