Using the single-chip microcomputer STM32F407VGT6 as the main control chip,the detection of various voltages and currents is realized,and the detection of multiple voltage signals is realized through the use of multiple switches.The detection signals of different voltage and current circuits are adjusted and sent to the A of the single-chip microcomputer.The/D conversion unit performs data collection and judgment,and judges the voltage state of the power metering device.At the same time,in order to realize the remote monitoring of the system,a remote monitoring system is designed,using the DP83848 chip to realize data Ethernet communication,transmitting the data to remote viewing,and real-time judgment of the voltage status of the detected power metering device.The actual application verification of the designed detection system has been carried out.The experimental results show that the designed system detection accuracy can reach 100%,which meets the functional requirements of actual applications on site.
