摘要
面向电能表国际建议IR46标准提出的法制计量与非法制计量软件分离的要求,研究基于单MCU策略的智能电能表软件法制计量设计,将法制计量以及计量必须的组件设计为最小"系统"的基表,内部采用积木式、模块化结构,法制计量基表部分不能改变和升级,其它应用功能模块独立设计并可任意配置和在线升级;通过采用操作系统控制MPU进行分层分块隔离和保护,通信协议基于DLMS/COSEM高级计量架构,兼具开放性、互操作性,设计统一的带保护的外置通信模块接口,自适应各种通信模块。
For the international reeommendations IR46 standard of the energy meter proposed legal measurement and non-le- gal measurement software separation requirements,researched software legal design of the energy meter based on single MCU strat- egy,the legal measurement system and its necessary components designed as the smallest ＂system＂ of the base meter,designed by using modular strueture inside the meter,in order to each component was independent of each other ,legal measurement part can not change and upgrade.Other application tunetion modules were designed independently, could be arbitrarily eonfigured and online upgrade.Used operating system to control MPU tor layered block isolation and protection,communication protocol based on DLMS/ COSEM advanced metering arehiteeture,which is open and interoperable, designed a unified external communication module inter- taee whir protection tunetion, adapt to a variety- of communication modules.
