为提高用电信息管理系统中用电信息采集子系统的通信效能,提出了一种利用云通信等即时通信方式搭建用电信息传输通道的解决方案,在云通信的基础上对用电信息传输的技术进行了深入的研究和探讨。此外还提出一种采集器端分体式4G通信模块,并利用该模组搭建了以云端即时通信为核心的透明无线通信信道。针对抄表信息在公共网络中的传输问题,利用嵌入式安全控制模块(Embedded Secure Access Module,ESAM)提供的密钥参数,通过对标准哈希运算消息认证码(Hash-based Message Authentication Code,HMAC)、数据加密标准(Data Encryption Standard,DES)等密码学算法的研究,开发了一个基于ESAM模块的网络安全软件包,并在电量采集器应用软件中实现了网络安全算法,最后设计并实现了一种自动抄表协议包。

In order to improve the communication efficiency of the electricity information collection subsystem in the electricity information management system,this article proposed a solution to build an electricity information transmission channel using cloud communication instant messaging.On the basis of cloud communication,in-depth research and exploration have been conducted on the technology of electricity information transmission.This article proposed a collector side split 4G communication module and used it to build a transparent wireless communication channel with cloud instant messaging as the core.Aiming at the transmission problem of meter reading information in the public network,a network security software package based on the ESAM module was developed by using the key parameters provided by the Embedded Secure Access Module(ESAM)module,and by studying the cryptographic algorithms such as the standard Hash based message authentication code(HMAC),Data Encryption Standard(DES),etc3 And implemented network security algorithms in the application software of the power collector.Finally,an automatic meter reading protocol package was designed and implemented.
