摘　　要：IC卡水表用于对流经管道的水量进行精确计量,具有智能数字显示功能,可实现对用水的预付费管理。重点介绍了低功耗IC卡水表的设计方法。该水表选用PIC微处理器、PCF8563时钟/日历芯片、E2PROM及其他微功耗器件和电路来实现水量的计量和控制,具有可靠性高和功耗低的特点。The IC card water meter which can realize intelligent and digital display is used to measure the water current in pipe and manage prepaying of water. A design of IC water meter with very low power consumption was introduced. This design adopted the advanced PIC microprocessor, PCF8563 clock calendar chip and E^2PROM, other little consumption components and circuits to realize the measurement and control of writer volume, it had high reliability and very low power consumption.
