The electric energy data acquisition of power users has realized remote automatic acquisition. The tool for remote automatic collection of electric energy data is various metering automation terminals installed on the site. The data transmission of the automation terminal depends on various communication channels. When the field signal strength is insufficient and the communication module of the metering automation terminal cannot work normally, the terminal is offline and the data collection fails. At this time, it is necessary to solve the problem of insufficient signal through other methods, ensure the real-time communication of the terminal. This paper will introduce a technology to enhance the communication ability of terminal communication module, and illustrate the whole picture of the device through practical cases.展开更多
