With the successful networking and all-round application of the National Beidou Satellite Communication System, an automatic meter-reading system based on Beidou satellite communication technology is proposed, as well as the establishment of system software and hardware platform. In order to realize the application of Beidou communication system in power centralized reading system, The urgent task is to solve the function realization of the remote communication unit of the acquisition terminal, including hardware structure design, communication protocol conversion and communication transmission, and conforming to the existing communication protocols and standards. The difficulty of this subject lies in adding Beidou communication module into the solidified structure of the existing communication unit, to achieve the synchronous transmission of the collected data and Beidou position information. Through processing in accordance with the protocol, the electric energy data of the collected terminal and Beidou information can be uploaded to the main station of the system, and the real-time safe and reliable requirements can be met.
