基于改进QMH的旋转机械多参数复合传感监测系统设计与实现
Multi-parameter Composite Sensor Monitoring System for Rotating Machinery Based on Improved QMH
摘要
Abstract
To overcome the shortcomings of traditional rack-mounted rotating machinery monitoring systems,such as inconvenient installation,poor versatility,high cost,and weak coupling of new sensing technology,a portable rotating machinery real-time monitoring and diagnosis system has been built,which can perform real-time measurement of multiple parameters of electrical measurement signals such as sound emission,vibration,strain,speed,and torque,and fiber Bragg grating sensing signals.A high-speed data acquisition program for the collection controller was built using a producer/consumer architecture,and an improved queue message handler(QMH)design pattern was used to develop a data acquisition upper computer program,achieving high-and low-speed data collection.The function of high-and low-speed data buffers was defined to reduce the problem of program stuck and low-speed data loss caused by high-speed data storage.The upper computer software for data analysis was developed to realize data playback and data time-frequency analysis.The system can achieve the online monitoring,data storage,and diagnosis of multiple parameters of the rotating machinery.关键词
