Plant abnormity monitoring device based on DCS system

The invention relates to a plant abnormity monitoring device based on a DCS system. The system comprises a detection module, a management module and a maintenance module, the detection module is in signal connection with the management module, and the management module is in signal connection with the maintenance module; the detection module is used for collecting working state signals of each hardware module of the DCS system and sending the working state signals to the management module; the management module is used for receiving the working state signal, judging whether the DCS is abnormal or not according to the working state signal, and sending an abnormal signal to the maintenance module if the DCS is abnormal; and the maintenance module is used for receiving the abnormal signal and sending a corresponding maintenance signal according to the abnormal signal. According to the invention, the abnormal hardware module in the DCS system can be monitored in real time, the adverse effect on the DCS system fro
