Problems solved by technology

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 trough belt conveyor to not be interlocked, seriously affecting the control of the fully mechanized mining face System stable production

Abstract

The embodiment of the present invention proposes a control system for fully mechanized coal mining face, the system includes: the acquisition module is electrically connected to the input end of the lower computer, and the output end of the lower computer is electrically connected to the input end of the induction current isolation module , the output end of the induction current isolation module is electrically connected to the fully mechanized mining face controller; among them, the acquisition module collects the working state information of the belt conveyor along the groove, and inputs it through the input end of the lower computer, and the lower computer generates control instructions according to the working state information , output to the induction current isolation module through the output terminal of the lower computer, the induction current isolation module generates a start signal or a stop signal according to the control command, and the fully mechanized mining face controller receives the start signal or stop signal, and according to the start signal or stop signal, Executing the start or stop operation can prevent the inherently safe cables from the lower machine from being induced by the power cables on the monorail crane to cause a large current to cause the working surface equipment and the down-trough belt conveyor to not interlock.

Description

Technical field [0001] Embodiments of the present invention relate to a control system for a comprehensive surface of coal mine. Background technique [0002] Compoundized working surface equipment and tank belt machines in the control system for coal mines in the prior art are unlocked by the next machine. When the tank belt is turned on, the comprehensive work surface equipment automatically stops. [0003] However, the console control interlock failure event occurs. After investigation and analysis, it was the local electric cable arising from the next machine. The power cable in the monorail cell should be caused by the power cable, causing the working surface equipment and the tank belt machine without interlocking, seriously affecting the control of the integrated work. The system is stable production. Inventive content [0004] Invention to solve problems [0005] It is an object of the embodiment of the present invention to propose a control system for a comprehensive s...
