Abstract: In order to effectively solve the above problems, based on wireless communication technology, a shearer coal cutting tracking spray system was designed, the overall structure of the system was designed, the tracking and positioning technology of the shearer was analyzed, the spray control box was designed, and the spray function simulation experiment was carried out. The results showed that the spray system could reasonably open and close the electric ball valve according to the actual spray demand, achieving a better spray dust reduction effect. After the wireless communication technology was used in the equipment of the spray system, the equipment The spray system is easier to install and maintain, and the application effect is good. The dust suppression system has certain promotion and application value.
