基于Si4438的无线智能电表设计
Design of wireless smart meter based on Si4438 transceiver
摘要
Abstract
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.关键词
