During the "13th Five-Year" period, China's distributed photovoltaic power generation will enter the fast lane of accelerated development. In view of the problems of low efficiency of data transmission, single transmission mode and inability to store data in the existing monitoring equipment, a distributed photovoltaic data collector based on ARM Cortex-M3 embedded processor is proposed in this paper, which is based on the distributed photovoltaic power generation monitoring equipment, which is distributed and limited in network. The scheme is based on hardware and software two. The data collector is designed to realize the functions of remote data transmission, storage backup and local display. The collector realizes the acquisition of the data of the inverter through the RS485 interface and the Modbus protocol, realizes the remote transmission of the data through the GPRS module and the TCP/IP protocol, and uses the LCD to display the data of the collector and the data collected by the SD card. The experiment shows that the distributed PV data collector has a high success rate of data transmission, and solves the problem of distributed photovoltaic power generation. It will have a good application prospect in the field of photovoltaic power generation.
