A fault diagnosis method for XPSI board of high voltage generator is presented in this paper.The fault causes of XPSI board are located by diagnosing five core chips on XPSI board.The system takes STM32F103RE chip as the control chip,collects the test point voltage value of each chip detection circuit,transmits the collected voltage value to the upper computer through RS-232 serial port,and displays it in the serial port debugging assistant.By comparing the actual volt-age value collected by each circuit with the theoretical value,the system can determine whether the chip is damaged,and thereby realize fault diagnosis and location of XPSI board.
