Embodiment Construction
[0049] see figure 1 , the state monitoring device of the process industry complex electromechanical system of the present invention, comprising:
[0050] Human-computer interaction module: used to realize the interaction between the user and the status monitoring system, including the input and output of system status monitoring information, calling the data acquisition module, data preprocessing module and data analysis module. It can modify and update the system fault case library, manage historical / real-time monitoring data and call the data analysis module for status monitoring.
[0051] Data acquisition module: used to extract the historical status monitoring data of the system and the real-time monitoring data generated by the DCS control system during the system operation.
[0052] Data preprocessing module: used to remove the Gaussian white noise of the monitored variable data, and standardize the collected data to remove the influence of dimension for subsequent anal...
