to the characteristics of the existing coal loading systems,automation proposed reform program. With S7-200 series PLC and PC,to achieve automatic control of the entire loading process. Through the PC,and PLC,PC and PC-machine and industrial communication with ifeld instrumentation to achieve PC loading system on the PLC real-time control. Through the analysis of the entire loading process,with the Ladder written communication module,data conversion,adding coal,a status code of the transmission process and the loading accuracy control procedures. Labs Simulation results show that loading system of the design can meet the technical index requirements,can be as accurate as real-time tests and accuracy of loadingsystem. The Function and have accuracy,searching so,solve the discharge,transmission,load and other aspects of the problem. Practice has proved that:loading process efifciency and automation have reached the higher loading was achieved on Automatic Control. The rapid development of the ifeld of automatic control for coal,electricity, telecommunications and other industries has brought great economic beneifts.
