基于机械式读数电度表硬件改造的远距离抄读

现在电力用户用电基本实行一户一表,每月都由抄表员到每家每户去抄读,这是一项非常耗时、耗力的工作.针对这一问题,对现有普通电度表进行硬件电路改造,将电表的机械数字转换为电数字信号,通过无线载波方式进行远距离抄读.将数据自动采集、传输及处理应用于电能管理系统中.它克服了传统的人工抄表模式的弊端.采用该项技术的特点就是在原电度表基础上加入电子线路的简单改造,而且整个系统经济投入低.

Improve the Hardware of Watt-hour Meter Reading Figure in Machinery to Achieve to Long-range Reading

It is a time-consuming job that reading electricity meter from door to door every month. So, improving the hardware of traditional watt-hour meter will change the machinery digit into electricity digit, and read electricity meter in long-rang with wireless carrier. Aautomatic collection, transfer and handling are applied to electricity energe manage system. It overcomes the weakness of traditional mannered reading model. The feature is that simple change the circuit to get the effect in low cost.
