用PIC12C508改造机械电度表

Remaking mechanical watthour meter with PIC12C508

介绍了一种以ＰＩＣ１２Ｃ５０８为核心设计的脉冲转换电路模块，该模块工作可靠，成本低，体积小，可方便地置于普通机械电度表中，将其改造为输出脉宽为８０ｍｓ的脉冲表。从而便于后续脉冲收集器对多路电表电量的收集和处理。这种设计方法有很强的实用价值。

This article introduces a module centralized on the microprocessor PIC12C508 designed for pules processing.This module is reliable,cheap and small.It can easily be put into the common mechanical watthour meter,which then produces pulse output with the width of 80ms so that pulse collector can gather and calculate a team of meters' watthour.
