Research on the Multi-in One Set Copy System Based on M-Bus

This paper describes the principle structure of M-Bus, especially the architecture of M-Bus bus protocol. According to the characteristics of M-Bus interface, the implementation scheme of multi-in one set copy system based on M-Bus is given. The composition and characteristics of each scheme are also introduced. The difficulty of promotion of "multi-in one" acquisition is illustrated, and corresponding suggestions on the development of "multi-in one" are put forward, which provides reference for the smooth realization of power grid construction project.
