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.
