以上网络仪表均采用RS485接口和MOD-RTU通讯协议，RS485采用屏蔽线传输，一般都采用二根连线，接线简单方便；通讯接口是半双工通信即通信的双方都可以接收、发送数据但是在同一时刻只能发送或接收数据，数据 传输速率为10Mbps。

RS485接口是采用平衡驱动器和差分接收器的组合，抗噪声干扰能力增强，总线上允许连接多达32个设备， 大传输距离为1.2km。

2  远程预付费电能管理主要功能

整个系统软件设计分为三个大块，分别是集中抄表服务系统，远程预付费电能管理系统，以及用户查询系统。

集中抄表服务程序常年运行，不间断定时对所有表进行远程抄表；远程预付费系统包含所有开户、售电、遥控及报表功能；用户查询机系统用于商铺查询个人信息、充值和用电情况；另外还可配置手机端查询网站，可用于商铺用户在手机网站终端上实时查询个人信息、充值、远程控制及每日用电情况，如果条件满足，还支持用户使用支付宝银联等方式远程自助购电。

主要特点如下：

a 快速配置，即装即用：将电表和通讯管理机配置导入系统就可以使用；

b 远程集中抄表：免去人工抄表，电表状态实时性 可精确到3分钟以内；

c 支持单独计价、多费率、阶梯电价：可对每块电表单独设置电价、费率和阶梯电价；
