In this paper, the microcontroller STM32F407 is used as the control core. The automatic detection device for protection against electric shock is designed and produced. The mechanism and characteristics of residual energy which is generated by the power cut-off at peak voltage are analyzed. This study has accomplished the design of peak voltage power cutoff and residual energy measurement system, software programming and hardware circuit construction, and displaying residual voltage and residual energy value through the touch screen. The device has stable performance and simple operation, and can accurately detect the residual voltage and energy value of electronic, electrical equipment and medical equipment. It has great significance for testing institutions and enterprises.
