In order to meet the needs of multi-point and remote vacuum monitoring of neutral beam injector,a multi-channel remote vacuum measurement system based on STM32 was designed.The system uses the sensor to measure the vacuum voltage signal of the vacuum chamber.The sampling chip ADS1256 measures the sensor voltage signal after the signal conditioning circuit is conditioned,and uses STM32F103ZET6 as the main control chip,combined with the analog-to-digital conversion circuit,the reference voltage generating circuit and other circuits transmit the processed data from the Ethernet to the host computer,and use the host computer software to realize real-time monitoring,early warning and analysis of the vacuum state of the neutral beam injector.The test results show that the system is stable and efficient,and it is suitable for vacuum measurement of neutral beam injector.
