Behavior Monitoring and Abnormality Diagnosis Method for the Automation Equipment
Aiming at shortages of behavior monitoring and diagnosis in the Automation Equipment,a behavior monitoring and abnormality diagnosis method for the automation equipment was proposed. Based on finite state automaton,equipment was divided into many modules,and equipment state and transition were recognized by the state set and state change of modules,and an equipment behavior state model was achieved,so that this model can accurately describe the operation of the equipment. By comparing the upcoming equipment actions,states and state transition path with the defined equipment behavior state model,and the abnormal behavior was detected during the operation process of the equipment. Finally,an equipment behavior monitoring prototype system based on the equipment behavior state model is implemented. The experimental results show that this model can effectively detect the abnormal behavior of equipment.
