Control system for fully mechanized coal mining face of coal mine

Abstract

The embodiment of the invention provides a control system for a fully mechanized coal mining face of a coal mine. The system is structured such that a collecting module is electrically connected to aninput end of a lower computer, an output end of the lower computer is electrically connected to an input end of an induction current separating module, and an output end of the induction current separating module is electrically connected to a fully mechanized coal mining face controller. The collecting module collects working state information of a crossheading belt conveyor, the working state information is input by the input end of the lower computer, the lower computer generates a control command according to the working state information, the control command is output to the induction current separating module through the output end of the lower computer, the induction current separating module generates a start signal or a stop signal according to the control command, and the fullymechanized coal mining face controller receives the start signal or the stop signal and executes starting or stopping operation according to the start signal or the stop signal, so that a phenomenon that equipment on a working face and the crossheading belt conveyor are not interlocked as a large current of an intrinsic safety cable extracted by the lower computer is induced by a power cable on amonorail crane can be avoided.

Description

technical field [0001] The embodiment of the invention relates to a control system for a fully mechanized mining face in a coal mine. Background technique [0002] In the prior art, in the control system of the fully mechanized mining face of coal mines, the equipment of the fully mechanized mining face and the trough belt conveyor are interlocked through the lower computer. When the trough belt conveyor stops, the fully mechanized mining face equipment will stop automatically. [0003] However, console control interlock failure events often occur. After investigation and analysis, it was found that the intrinsically safe cable led by the lower computer was caused by a large current induced by the power cable on the monorail crane, which caused the working face equipment and the belt conveyor along the trough not to be interlocked, seriously affecting the control of the fully mechanized mining face The system is stable in production. Contents of the invention [0004] ...
