The fully mechanized working face dust suppression monitoring system in most infrared sensors monitoring shearer position

working reliability and real-time performance is difficult to meet the requirements of the system in the harsh environment and complex fully mechanized working face. studies A spray and dust suppression system of fully mechanized mining face based on CAN bus and wireless sensor networks（ WSNs）technology. The ZigBee terminal node of WSNs is installed on the shearer body for collecting and transmitting operation state of equipment. The routing node is transmitted to the hydraulic support through WSNs

and location of the shearer can be determined in realtime according to the location algorithm. Each routing node is connected through CAN bus to ensure the high efficiency and reliability

and the data is finally uploaded to the ground database through the ground CAN bus interface. Finally

the feasibility of monitoring network communication is verified by simulation experiments.
