The design of energy-efficient monitoring terminalfor power supply and distribution system of enterprise based on stm

The significance of energy-efficient monitoring for power supply and distribution system lies in guidi ng enterprise to implement energy-efficient reconstruc tion, reducing energy consumption, and alleviating energy supply and construction pressure. According to the standard GB/T16664-1996 of People’s Republic of China, daily load factor, load coefficient of tr ansformer and line cost rate need to be monitored. For this reason, an energy-efficient monitoring terminal sys tem based on Coretex-M3 STM32F103 was presented in this paper, the system architecture, software flow chart was also provided, and the core circuit was described. The terminal system, presented in this p aper, has some superiority of fully function, simpl e structure, easy to use and high accuracy, and has a broad market prospect.
