Design of belt conveyor control system is a very traditional subject, now with many control instruments of various advanced precise appearance, design of belt conveyor control is also more and more advanced, more and more perfect, various references is also beyond count. The system uses Mitsubishi FX2N series programmable controller (PLC) as the control core, the system uses a PLC control 4 belt machine, the whole control system sets up a control room. Use PLC to control the belt conveyer, realizes the reverse start, stop, failure to stop order, emergency stop function, and a manual control and automatic control two control mode, so as to realize the automatic function of the coal handling system. PLC due to the use of modern large scale integrated circuit technology, used the strict production craft manufacture, the internal circuit has adopted the advanced anti-jamming technology, with high reliability. In addition, self - detection function with PLC hardware failures, failure to issue timely warning information. In the application software, users can also fault self diagnosis program of peripheral devices.
