双向计量型智能电表系统的设计

摘要

Aiming at the actuality that the new energy power supply systems are continuously upgrading and being grid-connected, designing novel intelligent ammeter with bidirectional function is imminent. Based on AMI model, with STM32F103VET6 as the main control chip, and BL0929 as electric energy metering chip, the directional intelligent metering system has been designed. The structural principle, hardware and software design of the system are introduced specifically. The tests show that the system features many merits, e. g. , bidirectional accurate metering, reliable data storage, user friendly man-machine interaction and 3G high speed communication, etc. It well satisfies the demands for new energy source power supply system and modern intelligent control, and possesses broad applicable prospects.%针对新能源供电系统不断并网和升级的现状，设计具有双向计量功能的新型智能电表迫在眉睫。基于AMI模型，设计了一款以STM32F103VET6为主控制芯片、以BL0929为电能计量芯片的双向计量型智能电表系统。具体介绍了系统的结构原理、硬软件系统设计。测试表明，该系统具有双向计量准确、数据存储可靠、人机交互友好、3G通信快捷等优点，可以更好地满足新能源供电系统和现代智能控制的需求，具有广阔的应用前景。
