摘　　要：采用专门针对我国智能电表推出的SUB-GHz无线收发器Si4438作为无线传输模块,AT89C51作为微处理器,在其上植入μC/OS-Ⅱ实时操作系统,电能计量使用高性能ADE7758芯片,设计并实现了一款高性能无线智能电表。该系统提供电能质量的监视、提供双向计量、多参数电量实时采集和控制、存储,支持双向通信、远程时间同步,能根据进行远程编程设定以及软件升级。实验证明,该智能电表满足国家标准中规定的0.2 s要求,具有功能完备、运行稳定、精度高和实时性好等优点。The high-performance wireless smart meter with SUB-GHz wireless transceiver Si4438 as a wireless transmission module（for the smart meters only in China）,AT89C51 as its microprocessor（in which μC/OS-II real-time operating system is implanted）,and high-performance ADE7758 chip（for electricity metrology）was designed and implemented. The main functions of the system are power quality monitoring;two-way metrology;multi-parameter real-time data acquisition,control and storage;support of two-way communication and remote time synchronization;setting of remote programming and software upgrade. Experi-ment results show that the system satisfies the 0.2 s requirement specified in national standard,and has maturity function,sta-ble running,high precision and good real-time performance.
