下一代多芯智能电表中程序在线升级的技术方案

Technical Scheme of On-line Program Upgrading in Next Generation Multi-core Intelligent Meter

随着泛在电力物联网概念的提出,国家电网“三型两网”建设目标的逐步实施,对下一代多芯智能电表中管理芯片等的程序升级需求显得更加强烈,传统方案需要使用BOOT程序和APP程序,采用BOOT程序进行APP程序的升级,只能实现整个APP应用的升级,一旦采用低速通信介质,会造成升级效率低下等问题,与此同时,对应用程序空间的浪费较大。基于上述需求,本文主要介绍了一种技术方案,可以实现管理芯片功能块的灵活升级。

With the concept of SG-eIoT put forward,the gradual implementation of the construction goal of"three types and two networks"in the state grid,the need for program upgrading in the next generation of multi-core smart meters becomes more intense.The traditional schemes need to use BOOT program and APP program,and use BOOT program to upgrade the APP program,which can only achieve the upgrade of the whole APP application.Once the low-speed communication medium is used,the upgrade of the whole APP application will be made.At the same time,it wastes a lot of application space.Based on the above requirements,a technical scheme is proposed in the paper,which can realize flexible upgrade on-line of management core function blocks.
