Abstract: In view of some problems of video monitoring of shearer and two-dimensional plane monitoring such as blurring monitoring images, inability to display running status of shearer real-timely and so on, a kind of remote monitoring system of shearer was put forward which was based on PLC and Quest3D. The system uses PLC, computer, remote console and others to compose hardware platform, uses Quest3D software to realize virtual monitoring platform, and realizes communication between software and hardware by data interface of virtual reality and FX2N PLC programming port. The test result shows that the system can realize real-time display of running status parameter of shearer and remote control of shearer.
