摘要
提出了电能数据采集终端一种改进型冗余备份方案,该方案针对单RS485口电能表和双RS485口电能表采用不同的处理策略,并给出了具体的实现方法。经实验验证,本方案简易、可行。
In this paper, an improved redundancy backup scheme for electric data acquisition device is presented, which utilizes various strategy to process electric meters with single RS485 communication port and those with dual RS485 communication ports. Detail implement method is introduced as well. The scheme is proved to be simple and feasible by experiments .
