摘要
针对智能电能表固件升级的需求,以及IR46国际建议中要求升级不影响计量功能的要求,文中介绍了一种IR46智能电能表固件在线升级方案。定义了升级接口类的属性和方法,对升级的初始化,固件传输,固件校验,固件激活过程进行了设计,并给出保证固件替换期间分时电量正确累积的方法,保证了电能表升级的可靠性及分时电量的准确性。该方案对于电能表在线固件升级的开发具有一定的参考意义。
According to the demand for smart meter firmware upgrading,and the requirements of the IR46 international proposal that the upgrade shall not affect the measurement function,this paper introduces a IR46 smart meter online firmware upgrading design.The attributes and methods required for upgrading interface class are defined,the processes of firmware initialization,transmission,verify as well as activation are designed,and the method to ensure the correct accumulation of the TOU energy during the replacement of the firmware is given,so as to ensure the reliability of the upgrading and the accuracy of TOU energy.The scheme has some reference significance for the development of online firmware upgrading of smart meter.
