China's CMC-based smart meter technology has made important breakthroughs

[Chinese instrument network instrument research and development] At present, all countries in the world are reforming the traditional power industry production methods and management methods, so that the monopoly of the power industry to open commercial operation and management direction. With the rapid development of technologies such as information, internet, and internet of things, fast, accurate, economical, real-time and reliable access to various data managed by electricity is the automatic settlement of expenses, the analysis of usage, the detection of the running status of meters, and the load. Processing and other application management basis. The gradual maturity of the implementation of automatic meter reading is not only conducive to the establishment of the information network of the power supply sector, but also conducive to the construction of various information systems in the future.

Recently, the project of “Development and Application of CMC-based Smart Meters” in the advanced manufacturing technology of the 863 Program passed the technical acceptance.

Under the support of the National 863 Program, Shenyang Zhongkebo Micro-Technology Co., Ltd. and Zhejiang University cooperated with Zhejiang University to develop a controllable on-chip control system (Control Module on Chip, abbreviated: CMC) based on the smart meter terminal, Collector, concentrator and other types of meter reading system key equipment, and smart meter reading software platform for the development and design. The CMC-based smart meter reading system uses micropower wireless communication to avoid the construction and investment of new communication networks. It has the advantages of small circuit modification, low cost, easy use, and maintenance-free advantages, and improves the stability of the meter reading system. Sex and reliability. At present, the CMC-based smart meter terminals, collectors, and concentrators developed by the research group have been successfully applied to smart meter reading systems, including civil electricity meters and industrial field electricity meters, and have achieved scale. After a long period of operation, the meter reading system is stable and reliable, and can fully meet the customer's need for accurate and stable meter reading.

The research and development of smart meter terminals and meter reading systems for CMC's own core hardware and software broke through the status quo of the critical core chips of smart meters relying heavily on imports, realized localization of the core controller technology in the meter industry, and accelerated the intelligentization process in the power industry. It is of great significance to the construction of smart grids.
