DRD intelligent electro-hydraulic control support system consists of three parts: electric control main valve, electro-hydraulic control main valve, and auxiliary valve. The electrical part includes central computer, underground server, controller, power supply, Odometric sytem, pressure sensor, infrared transmitter, inclination sensor, wireless remote control, multi-function sensor and personnel positioning system, etc. Electro-hydraulic control main valve group includes main valve, solenoid valve; Auxiliary valve part includes check valve for leg, check valve, double check valve, relief valve and so on.
DRD intelligent electro-hydraulic contol system has the following functions for the fully mechanized longwall, such as: group automatic control for nei***oring shields basic of fully mechanized longwall, following-Shearer automatic control, communication and remote monitoring on the ground. It also has new following functions: wireless remote control, identification of person’s position, personnel safety protection, monitoring the status o height measuring and inclination. It can realize low energy consumption, high efficiency, safety production, to meet users' requirements for safe production and maximization of benefits.
