Design of CRH Auxiliary Power Supply Testing Device Based on WIFI

This paper introduces a design scheme which is used to detect the voltage and current of CRH auxiliary power supply system based on WIFI. The design uses STM32 MCU as the core controller. The intelligent acquisition instrumentation researched and developed can real-time measure and collect the volt- age and current when 380 CRH auxiliary power circuit of three-phase load start-up and normal working, measure the change of current when the battery charge and discharge, and send the data to the server in the form of wireless. This scheme uses voltage and current transformers, after the RMS conversion for da- ta processing , so that the voltage and current are displayed on the PC in the form of WIFI and through the touch screen to display and set the parameter. The test device provides a real-time monitoring solution for CRH auxiliary AC and DC voltage and current of the power supply system.
