To reduce code amount of embedded 一个开放的网络，电力用户从被动的接受者转变成 communication software in watt-hour meter and improve the 系统运行的友好参与者，电网和用户的互动是在大 execution efficiency of communication software, on the basis 量信息采集、数据处理和相应决策机制的基础上完 of analyzing characteristics of encoding table for data [1] 成的 。智能电表既是信息的检测和收集者，也是 identification in DL/T 645—2007 protocol, data that is metered, [2-4] processed and recorded by a watt-hour meter is organized and 电网和用户之间数据传递的桥梁 。它具有的双向 stored rationally. A smart meter acts as a slave station, which 通信功能是实现互动的基础，其先进的通信设施和 receives communication commands from a mas
