Infrared receivers mounted on brackets and infrared transmitters mounted on coal mining machines are used for work surface automation, respectively, to receive and transmit information about the location of coal mining machines. Using the infrared transmission and reception method, the digital signals receive the monitoring data of the working direction and working position of the coal machine. During the movement of the coal mining machine, the infrared receiver on the bracket corresponding to the infrared transmitter of the coal mining machine (on the horizontal line) receives an infrared signal from the infrared transmitter. Accuracy of determination of the location of the coal mining machine ±1 pcs. The infrared receiver is connected via the connector and the bracket controller, converts the received infrared signal into an electrical signal to be transmitted to the controller, which processes this data and directs the corresponding bracket to perform the corresponding automatic actions using the launch and communication program. Technical parameters as follows: PU launch angle: 30°Explosion-proof type: Mine physical safety type Number of units: Receiver: Receiver: 1 unit / 1 unit Starters: 1 installation / working surface
