A field fault automatic detection system was designed to address the problems of high failure rate and high workload in thermal control systems of thermal power units.Matching filtering and integrated DSP were introduced,and functions such as data acquisition,feature extraction,and fault detection algorithms were integrated.The program loading control method was used to load fault detection instructions onto the DSP integrated processing chip,completing the automatic detection of field faults.After testing,it has been shown that the system has good scalability,high accuracy in detecting faults on thermal control sites of thermal power units,and can reduce the risk of misjudgment caused by human factors,providing strong guarantees for the safe and stable operation of thermal power units.
