Real-time online monitoring system for boiler Three-dimensional expansion based on intelligent rec-ognition
Thermal power units usually use mechanical expansion indicators to detect the three-dimensional expansion displacement of boilers and pipelines during the start-up and shutdown stages.Manual inspection of the indicator scale data can detect abnormalities in the process of heating and pressure rise of boilers and pipelines,thus preventing leakage accidents.In response to the common problems of manual inspection of boiler expansion displacement,this article proposes a three-dimensional real-time online monitoring method for boiler expansion based on intelligent recognition.An industrial-grade camera is used to obtain three-di-mensional expansion data for an expansion measurement point.Through application and measurement in the boiler field environment,the accuracy,real-time performance,and reliability of the system data acquisition are verified.The use of the method could replace the original manual reading method,and can effectively improve the intelligence level of power plants.
