The invention discloses a wireless communication system of a coal mining machine, which comprises a controller, a signal conversion device, a signal sending device, a signal receiving device and a receiving antenna. The controller and the signal conversion device are arranged in an explosion-proof electric cabinet, the signal sending device is embedded on the cover plate of the explosion-proof electric cabinet, the controller is connected with the signal conversion device, the signal conversion device is connected with the signal sending device, the signal receiving device and the receiving antenna are arranged on the middle frame of the working surface of the coal mining machine, wireless connection is established between the receiving antenna and the signal sending device, and the signalreceiving device is connected with the receiving antenna. According to the wireless communication system of the coal mining machine, wireless connection is established between the signal sending device and the receiving antenna; by adopting wireless communication, the problem of line interference does not need to be considered; the signal receiving device can be conveniently installed at an appropriate position; the system failure caused by line damage in the working process is avoided; and the maintenance difficulty is reduced.
Description
technical field [0001] The invention relates to the technical field of coal mining equipment, in particular to a wireless communication system for a coal mining machine. Background technique [0002] The coal mining machine is one of the important equipments to realize the mechanization and modernization of coal mine production. Mechanized coal mining through the coal mining machine can reduce physical labor, improve safety, and achieve the purpose of high output, high efficiency and low consumption. In order to realize the automatic control of the shearer, during the operation of the shearer, a network connection needs to be established between each component to realize data transmission and interaction. [0003] In the prior art, the shearer data transmission adopts RS485 communication line or CAN bus and other wired connection methods, and the line layout has large interference and difficult maintenance. Contents of the invention [0004] In order to solve the above-me...
