Design of Underground Belt Transportation Control System of Metal Mine and Its Applicatio

In view of problem of bad reliability that original belt transportation system of one metal mine is controlled by relay, the paper proposed a reform scheme of belt transportation control system based on ControlLogix technology. The system uses ControlLogix technology to realize any combination of driving and motion control of belt transportation system; it uses fiber communication and network redundancy technology to realize functions of device configuration, data collection and remote fault diagnosis; it uses electronic overload relay to realize protection for motor; it uses visual man-machine interface to realize real-time monitoring and control for working state of belt transportation system. The actual application showed that the system improves reliability of belt transportation system.
