针对电能抄表系统的通信问题提出了经由RS-485网络及公用电话线（或电力载波、微波等信道）进行电能信息近、远程传输的方案，实现了电力用户（变电所）与供电局营业管理系统之间的微机通信，具有一定的实用与推广价值。
Aiming at the problem of the communication of electric meter reading system, a scheme of near and far transmission of electric energy information via RS-485 network and public telephone line (or power carrier and microwave channel) is put forward, which realizes the connection between power users (substations) Business management system between the computer communication, has a certain practical and promotional value.
