Abstract: This paper describes a single vacuum pump operating parameter monitoring system. The system consists of a main master chip STM32F103ZET6 microcontroller and corresponding monitoring sensors. The system's overall design, measurement principles and some key technologies are introduced. The hardware design, software programming, transmission test and other processes are elaborated in detail. The system can acquire and display the operating parameters of the pump, including temperature, pressure, rotating speed and so on. It can also communicate with the PC host computer. The as-designed system is compact in size, low in power consumption, high in reliability and strong in anti -jamming capability, which can effectively realize the real -time monitoring of vacuum pump operating parameters.
