    The invention relates to agriculture, namely to technical. means used for irrigation of agricultural crops, and can be applied in wide-grip front-mounted rainfall machines. A known sprinkler system containing a pipeline with driven supports. In this system, the direction of the engine is performed at one end of the pipeline, while the supports at the opposite ends of the pipeline are controlled in such a way that the first support serves as a pivot for the pipeline, and then other, and the entire pipeline moves as a series of alternating arc TiJtieKTOpHH | 1J, Pedstatkom this system makes it impossible to move the ends of the pipeline with the same speed. Closest to the invention in technical essence and the achieved result is a sprinkling system j containing a frontally movable pipeline, placed 1st on supports with drives, and a device controlling the movement of the pipeline along a predetermined course, interacting with the guide laid along the field and drives of the pipeline supports 2J, A disadvantage of the known system is the structural complexity, the Tsa: of the invention, the simplification of the design and the improvement of the accuracy of the pipeline movement along the course. gaets Teii. that, in the sprinkling system, the device for controlling the movement of the pipeline is designed as a pipeline protruding ahead and secured by a lever on it, at the end of which sensors are installed that interact with the guide and are connected to the drive supports oppositely located near the ends of the pipeline. At the same time, the pipeline motion control device includes means for generating an electromagnetic field around the guide. In addition, the sensors contain means. Electromagnet ™ sensitive field. Moreover, the lever protruding in front of the pipeline is fixed to the nemsharnyri. In FIG. 1 shows the sprinkling system, general view; in fig. 2 central pipeline support; in fig. 3 - diagram of the sensor; in FIG. 4, the same, the coil to the right of the wire; in FIG. 5, the same, the coil to the left of the wire; in fig. 6 is an electrical block diagram of the detector circuit; FIG. 7 is a circuit diagram of the control circuit; Fig. 8 shows a device for mechanically connecting sensors of a lever and a guide; Fig. 9 shows a sprinkling system of another embodiment; in fig. 10 is a diagram explaining a version of the control system. The sprinkler system contains pipeline 1, placed on supports 2 with drives 3, for example electric motors. The sprinklers 4 are located on line 1 for supplying water or fertilizer water to the field. Pipeline 1 consists of separate sections 5, each of which is supported by the farm 6 and is connected to the next section by a flexible connection 7.- The pipe moves along the open-. That channel 3 Water is taken from it by a pump9 ,. The pump 9 and the suction pipe 10 are moved together with the end support 2. The pipe moves along the guide 11, which is delivered in the form of a conductor, diving into the ground. The conductor may repeat the outline of the irrigated floor. Each intermediate support 2 is provided with micro-pockets for recording the angular displacement of adjacent sections of pipeline 1, Central support 2 (FIG. 2) has a horizontal beam 12 with wheels 13 driven by drive 3, the sprinkler system is equipped with a device for controlling the movement of pipeline 1 at a predetermined course, completed in the form of a lever 14 mounted on the pipeline and protruding in front of it, mounted on trusses. 6 by means of tension 15, Lever 14 is rigidly fixed on the pipeline at an angle of 90, although some deviation is permissible. On the lever 14, the sensors are mounted: and 16, located above the guide 31 and made in the form of antenna coils 17-19, the coil 19 is a coil, compared and oriented with its axis horizontally and across 3 relative to the guide 11. The coils 17 and 18 are oriented with their own axes at an acute angle to the horizontal and vertical plane. Coils 17 and 18 are the same, only one works when the pipeline moves in one direction, and the other in the opposite direction. Coils 17-19 are means sensitive to an electromagnetic field around a conductor into which a constant frequency signal is fed through means for generating an electromagnetic field (not shown). The variable magnetic flux created by the buried wire from the superimposed negative signal surrounds the conductor in the ring-shaped radiation pattern, whereby a voltage proportional to the component of the flux vector that is projected along the coil axis is induced in each coil 17-19. The voltage phase in each coil is determined by the relative direction of the flow vector along the axis of the coil (this principle is shown in Figures 3-5, where the flow vectors are shown by arrows). Since the comparison coil 19 is horizontal, its vector component is always in the same direction. However, since the coils 17 and 18 are located at an acute angle and are oriented as indicated above, the magnitude and direction of the component of the vector cause a change depending on the transverse position relative to the conductor. When coils 17 and 18 are directly above the conductor, they do not have a component of the vector induced in the coil (Fig. 3). If the coil is to the right of the conductor, the vector component along its axis will be induced in one direction (Fig. 4), and when the coil is to the left of the conductor, the velocity component will be induced in the opposite direction (Fig. 5). One of these components of the vector will coincide in phase with the component of the vector induced in the comparison katus 19, and the other will not coincide in phase by 180. This phase difference is used in the detector and control systems for the waters of the annular supports 2. 10 The detector circuit 20 is designed to receive control signals. The output signals of the coils 17-19 are fed to the inputs of the amplifier and filter circuits 21-23, respectively. The output signals of the amplifier and filter circuits 21 and 22 are fed to a selective antenna circuit 24, which selects the corresponding signal, and coils 17 and 18 are fed to it. The output signal of the circuit 24 is fed to a threshold detector 25 and phase comparator 26. The output signal from the amplifier and filter 23, representing the comparison antenna is also fed to phase comparator 26, and the output signals of threshold detector 25 and phase comparator 26 are fed to direction selection logic 27, which produces output signals for use in the control circuit. As a precautionary measure, the output signal of the amplifier and filter 23 is also supplied to a threshold comparison detector 28, from where the output signal is fed to the safety circuit 29 of the output signal 30. The threshold detector 28 turns off the system if the output voltage of the comparison antenna drops below a predetermined level, which indicates that the sensor is outside a predetermined distance from the buried conductor. Outputs 30 and 3 of the detector 20 are connected to a control circuit (FIG. 7) containing a control block 32 for end support T., a control block 33 for another end support 2 and control blocks 34 for each intermediate support 2. The control circuit also contains a source 35 three-phase current for driving electric motor supports with a paste 36 relay connected to each motor. Another single-phase current source 37 is connected by micro-switching of the telles 38. The output signal of the current source 37 is also provided via a percentage time relay 39, to the contact levers of the relay 40 and 41. The time relay 40 and 41 are usually turned off (as shown in Fig. 7) and translated TC in the on position only when the excitation of their coils. The outputs 30 and 31 of the detector circuit 20 are connected to the coils of the relays 40 and 41 and the normally-connected contacts of these relays are connected to the coils of the relays. 36,
    interacting with end supports 2 ,.
    In the device for mechanically connecting the sensors of the lever and the guide (Fig. 8), for example, a wire or a rail or the like is used as the guide 11. and it is located above. On the lever 1A, sensors are installed in the form of microswitches 42 located on both sides of the guide 11, so that one of the microswitches engages with the wire j when the lever turns to the right (Fig. 8) and the other turns off when it engages with the wire when lever 1A rotates to the left.
    In the sprinkling system of another variant, g-gs (4), the lever 14 is baptized on the pipeline 1 and is hinged for a huvorot around a vertical base. A wire located above the ground is used as a guide 11. The front end of the lever 14 is rotatably connected to the wire at point 43. Angle sensor (not shown registers the angle between the lever and the pipeline, detects its deviation from a given angle, for example, 90 °, and sends a signal to the opposite supports of the pipeline.
    The operation of the rain system in the first embodiment is carried out as follows.
    At the beginning of the movement, the end supports 2 begin to move, which form the corners with the adjacent sections and, accordingly, the intermediate supports begin to move in response to the microswitches being turned on and so on until the very last, central support, after which the intermediate supports align with the end supports, since the number their speed is greater and the entire pipeline is kept in a straight position.
    When the system deviates from the course, the sensor moves one side of the guide. When this happens, the detector circuit 20 aligns you, a signal that, through the blocks 34, stops the power supply to the corresponding end support 2 and it stops. The other end support 2 continues to move and the entire system, retaining the straight line, turns around the fixed support. By virtue of this, the sensor moves back to
    the zone 1 of the control d. and the removal of the back-up signal vt3 of the detector circuit, the switching of the block 34, and for the re-activation of the fixed-support drive. Again, both supports move across the field.
    The movement control of the system can also be accomplished by reducing and increasing the speed of movement of the controlled support.
    On long systems, the supports located near the end supports can be controlled in response to the sensor signal by significantly reducing their speeds.
    The system operation according to the second variant is carried out as follows.
    At the beginning of the two legs, the system moves along the path indicated by A (Fig. 10). Further, when the pipeline deviates from a predetermined course, the system shifts to the position. In this position, the hinge point of the lever 14 with the pipeline shifts to the right relative to the yew direction and the angle between the lever and the pipeline becomes sharp. The specified value of this angle is recorded by the angle sensor and the drive of the left end support is stopped. The other end support continues to move.
    By virtue of this, the entire system rotates around the unconnected support until the angle between the pipeline and the lever becomes equal to 90. When the system reaches position C, both end supports move forward at full speed. In this case, the adjustment of the stirring fumes is carried out by moving an imaginary point located at the end of an imaginary line equal to the length of the lever 14 in the direction of the guide 11 to align with the front end of the lever at point 43. The imaginary line forms an angle of 90 with the pipeline 1 and intersects the pivot point of the lever 14 from the pipelines 1. Thus, an imaginary point and line are equivalent to the coils 17 or 18 of the sensors 16 and the lever 14 of the first option;
    When the imaginary point is located to the right of the wire (Fig. 10), the left end support stops and the right continues to move until
    as long as the posture conditions do not reach an imaginary point behind the wire.
    When both end supports 2 are moved forward from position C, lever 14 starts to rotate and the angle between the lever and the pipeline becomes blunt. This causes the imaginary point to move left relative to the wire. When the angle between the lever 14 and the pipeline 7 becomes: up to a predetermined amount, this position is recorded by the sensor and the right end support 2 stops and the left continues to move until the angle between the lever
    and the pipeline, i.e., becomes 90, and the imaginary point will not again appear on the wire (position E). In addition, the movement between the O and E positions is in reality a pivotal movement around the right support 2. This continues until the end supports move at the same speed.
    The application of the invention will allow, with less expenditure of technical means and with high accuracy, to drive wide-range sprinklers on a given course.
