Abstract: In view of problems of big volume, inconvenient to change PLC program and high cost in control system of belt conveyor based on PLC, the paper proposed a design scheme of control system of belt conveyor based on embedded technology. It detailedly introduced design of hardware and software of embedded intrinsic safety controller, control driver and remote I/O module of the system. The actual application showed that the system solves problems in control system of belt conveyor based on PLC and has better stability, flexibility and friendliness.
