Due to the particularity of the running environment of the lightning current on-line record device, power supply of the device is inconvenient. It is the primary problem for the research and development personnel to consider how to reduce the device’s power consumption and ensure it continuously work in stormy weather. This paper introduces the lightning current on-line record device from the point of view of the software and hardware low power design. The device uses STM32F407 as the control core, completes lightning current data acquisition by using the ADC analog converter and DMA controller, and sends the lightning current data to the server through the GPRS wireless communication. Considering the power supply mode,low power device selection and software and hardware design,the design successfully controls the power consumption by using low power consumption modes on chip of STM32F407, which achieves the goal of reducing the power consumption and extends the device’s working time in stormy weather.
