Abstract: The remote control system of the signal operation equipment of the auxiliary shaft is an important part in construction of the digital mine. The system applies computer network technology， programmable controller technology， wireless communication technology， sensor detection technology and video monitoring technology， and is a digital network control system based on bus redundancy， Profibus-DP field bus control and industrial Ethernet. It is the inevitable trend of intelligent mine construction to reduce the number of post operators at each middle level of auxiliary shaft hoist， improve the safety and production efficiency of equipment， and apply to the long-term production conditions of underground mine enterprises by transforming the original system into centralized remote control and remote operation mode.

Key words: Auxiliary shaft hoist, Remote control, Signal operation, Wireless communication
