摘要

针对传统电能表软件远程更新模式在测量点档案与实际不符时会更新失败的问题，首先分析了传统集中式软件更新模式在档案，信道使用和存储方面存在的问题。然后提出一种基于分散组播模式的电能表软件更新模式，并给出基于该模式的各过程的软件更新具体方案。接着研究了原程序拷贝及回滚，更新程序的完整性及安全性的保障等更新过程中遇到的主要问题，最后通过实例测试，验证了所提升级模式的可行性。

Abstract

Aiming at the problems that the traditional remote update mode of watt-hour meter software fails to update when the measurement point file does not conform to the actual situation

firstly

the problems of the traditional centralized software update mode is analyzed in the aspects of archives

channel use and storage. And then

a software update mode of watt-hour meter based on distributed multicast mode is proposed

and the specific scheme of software update for each process based on this mode is given. Then the key problems in the process of updating such as the copy and rollback of the original program

and the protection of the integrity and correctness of the update program

are studied. Finally

the feasibility of the proposed upgrade mode is verified by experiments.
