| Abstract: | Based on the defect analysis of the PLC coal conveying control system in power plant, this paper puts forward a new method for on line defect judgement of the control system. This method can judge the actual defect source and decrease the software computation quantity by constructing the system defect judgement matrix and combining the PLC port state. |
