DEVICE OF AUTOMATED CONTROL OF MULTISUPPORTING IRRIGATION MACHINE OF FRONT ACTION FOR PRECISION IRRIGATION Russian patent published in 2014 - IPC A01G25/16 A01G25/09 G01N25/56 G01S19/05 

FIELD: agriculture.

SUBSTANCE: device of automated control of multisupporting irrigation machine of front action for precision irrigation comprises pipelines of right and left wings of the machine, mounted on trolleys with electric drive, unit of motion synchronisation with the course with a guide rope and a speed control unit of the machine motion. Along the irrigation channel a contact network is mounted on racks, which interacts with the current collector, which, through the telescopic mechanism is fixed to the trolley moving along the opposite side of the irrigation channel. The output of the current collector is connected to the input of the control panel, which output is connected to the input of the counter of electrical energy, which outputs are connected to the inputs of the microprocessor control unit and the frequency inverter. The inputs of the microprocessor control unit are connected to a timer, a system of course stabilisation, a synchronisation system of trolleys in line, sensors of path, setter of irrigation rate, setter of length of irrigation site, water metre and a pressure gauge mounted on the pipeline, and the outputs of the microprocessor control unit are connected to electric hydraulic shutter, frequency inverter, contactor, devices of trolley synchronising in line and the devices of stabilisation of the course of left and right wings, through a vacuum pump with a pump inlet, which outlet through the electric hydraulic shutter and the flow metre is connected to the pipeline. The microprocessor control unit is connected to the input-output of the interface device. The signal from the output of the frequency inverter is supplied to the electric drive of the left and right-wing of the machine, and the contactor output is connected through the electric motor to the pump inlet. The signal obtained from the humidity gauges mounted on the irrigated area of the field, enters to the irrigation control system through the GLONASS satellite, the signal from the irrigation control system through the GLONASS satellite is transmitted to the input-output of the GLONASS-receiver which output through the unit of signal analysis is connected to the microprocessor control unit, which output is connected to the GLONASS-receiver. The input-output of the microprocessor control unit is electrically connected to a sensor screen, and the output of the frequency inverter is connected to the input of the contactor. The output of the signal analysis unit is connected to the inputs of the irrigation control unit, which outputs are at the extreme driving support trolleys are connected to the input of the device of the course stabilisation and on the intermediate support trolleys are connected to the input of the device of the trolley synchronisation in line, of both right and left wings of the machine.

EFFECT: reduced consumption of irrigation water, fertilisers, electricity, elimination of insufficient irrigation and excessive irrigation.
