SYSTEM OF AUTOMATIC CONTROL OF EARTH-MOVING TRANSPORT MACHINE ACTUATOR IN PROCESS OF EARTH DIGGING Russian patent published in 2008 - IPC E02F9/20 

FIELD: automation of processes.

SUBSTANCE: system of automatic control of earth-moving transport machine (ETM) actuator in the process of earth digging consists of sensor of earth volume in front of actuator, sensor of earth physical and mechanical properties, sensor of fuel flow rate, sensor of actual speed of ETM movement, which is connected to the slave wheel, setter of reference signals, control unit and actuating mechanism. At that the control unit contains device of input, single crystal microcontroller, permanent memorising device and output device, and actuating mechanism consists of electric slides and hydraulic cylinders. Signal of automatic regulation clearance by parameter of instant efficiency factor is only sent under the condition of predominance of parameters measured by sensors above the reference signals. Specification of reference signals level is performed by information signal of sensor of physical and mechanical earth properties.

EFFECT: increases efficiency of ETM use at the account of ETM actuator control accuracy increase, capacity of ETM operation and energy savings.
