Abstract:
Aiming at the problems of reduced measurement accuracy and increased failure rate of key thermal instruments in thermal power units under complex industrial environments, which exacerbate the safety and economic risks of unit operation and environmental protection risks, a safety detection method for operational status is proposed. This method analyzes the interference mechanisms and fault modes of chemical analysis instruments in complex environments and constructs a detection model integrating multidimensional signal processing and intelligent diagnosis. The model employs an improved adaptive filtering algorithm for denoising and feature enhancement of the original signal to suppress environmental interference. Time-domain, frequency-domain, and time-frequency domain feature vectors characterizing the health status of the instruments are extracted and input into a Support Vector Machine classifier optimized by a Particle Swarm Optimization algorithm for state recognition, achieving accurate classification of instrument status. Analysis shows that the proposed detection method effectively overcomes complex environmental interference, with the accuracy for detecting typical fault states of instruments such as CEMS, pH meters, and density meters reaching over 98.5%. The proposed method significantly improves the accuracy of instrument status detection in complex environments, providing important technical support for the safe, stable, environmentally friendly, and economical operation of thermal power units, and possesses high value for engineering application and promotion.
