For the existing power meters, the signal acquisition accuracy is low and the data transmission mode is backward,a power meter with integrated wireless communication function has been developed.The hardware of the meter consists of power supply, power collection and measurement unit, communication unit, control and storage unit.The main control chip STM32F030 and the new digital multi-function metering chip V9203 are used to realize data acquisition and processing and local storage.The MCU uses the NB-IoT wireless communication module to upload the data collected by the meter to the OneNET cloud platform,to realize the user to view the power collection information of each meter through the front-end webpage login system at any time in the remote situation, which is convenient for monitoring and management.The experiments provesthat this power meter can collect power parameters such as current, voltage, active power and power factor efficiently and accurately and upload these data to the cloud platform in real time.
