一种基于单片机的新型IC卡预收费水表电路设计

The Design and Implementing of a New Type IC Card Water Meter Based on Singlechip

给出了一种基于ＰＩＣ单片机的ＩＣ卡水表电路。它采用先进的ＩＣ卡和单片机技 术，完成了水表从模拟式到数字式的转变，使水费的收取工作向自动化方向迈出了一大步。

The paper gives the circuit design and implementation of a new type of IC card and PIC-based water meter. It realizes the change of water meter from analog to digital and makes a big step toward the au- tomation of water preselling charge.
