Wireless remote control communication state detection system of coal mining machine

Abstract

The invention relates to the field of coal mining machines, in particular to a wireless remote control communication state detection system of a coal mining machine of a full mechanized mining face of a coal mine. The wireless remote control communication state detection system realizes a function of detecting whether the coal mining machine exceeds a wireless remote control range or not. The wireless remote control communication state detection system is provided with a wireless remote control system, a main controller and a voice alarm system; the wireless remote control system comprises a remote controller emitter and a remote control receiver, the remote controller emitter is a manual trigger type remote control emitter, the output end of the remote control emitter is connected with the input end of the remote control receiver in a wireless manner, the remote control receiver of the wireless remote control system is connected with the main controller through a CAN (Controller Area Network) bus, and the main controller is connected with the voice alarm system through a CAN bus. The invention solves the problem of out of control of the coal mining machine, caused by easiness in exceeding the wireless remote control range, when the coal mining machine is operated in a long-distance remote control manner; the remote control system is communicated with the main controller, and sends a command to the voice alarm system after determining a stable wireless remote control signal, and the voice alarm system reminds wireless remote control communication of being normal through voice.

Description

technical field [0001] The invention relates to the field of coal mining machines, in particular to a wireless remote control communication state detection system for coal mining machines in fully mechanized mining working faces. It realizes the function of detecting whether the shearer is beyond the range of wireless remote control, and sends out a voice alarm message to remind or warn the underground workers, which is part of the humanized design of the coal mining machine in the coal mine working face. Background technique [0002] The coal shearer is the core equipment of the fully mechanized mining face, and it mainly realizes coal breaking and coal loading by walking left and right on the scraper conveyor. During the working process of the shearer, there is a lot of coal dust and high humidity, especially the working environment near the shearer is even worse, and it is accompanied by the danger of partial side and roof leakage, so remote control operation is required....
