Monitoring and Control System of Digital Mine Hoist Based on Double Ring Networks

The paper introduced application status of industrial Ethernet in digital mine construction, proposed network framework of a digital monitoring and control system of mine hoist based on double ring networks and Siemens S7-200 PLC, and introduced software and hardware designs of the system. The system can realize monitoring functions of working status, running parameters, fault parameters and fault status of mine hoist and control functions of starting, accelerating, stably running, decelerating, stopping and emergency braking of mine hoist. The actual application showed that the system runs stably and reliably and has perfect detection and protection functions.
