探讨了终端用户电量计量采用机械和电子结合的电度表计量方法,进行了多用户分布式单片机多机通信、以及分布式多机与PC机通信等方面的研究.采用机械电子表作为记电器,结合了机械表保持永久记忆和电子表具有可编程的特点,利用单片机及接口技术终端对用户电量进行智能计量和储存、通过485系统总线将一定数量的用户终端组成一个多用户多机通信系统,采用多机通信系统的一台机作为主机经RS-232与PC机通信.PC机作为电能管理系统的服务器.系统实现了购电、用电控制、远程抄表的功能,弥补了人工抄表浪费人力、工作繁琐、容易出错的缺陷.

Electrical power meter is manually recorded, not only wasting a lot of time but also making data processing very difficult, because the terminal clients are distributed in different living districts. The mechanical-electric recording meters are adopted, which have characteristics of both mechanical-recording meters recording for non-lost data and electric-recording meters programming for interfaces. The used quantity of electrical power can be accounted and stored intelligently at the terminal client, using single chip micro-computer and related technology. Intelligent recording meters for dif...
