摘　　要：针对水表阶梯收费、用户远程抄表的需求,设计了一种无线远传阶梯智能水表。该水表以MSP430单片机和无线收发芯片Si4432为核心,该单片机功耗低,无线收发芯片传输距离远。介绍了系统原理、硬件结构、软件思路、数据远程收发流程。实验表明,该水表可以实现阶梯收费的功能。在1km通信距离内,传输速率低于100Kbps时,可实现数据的完整传输。该水表具有成本低、功耗低、防水性(密封性)能好的特点,是智能水表的发展趋势。Because of the requirement of step charge and remote gathering data of water meter, design a wireless remote intelligent water meter. The meter is based on 430 MCU and Si4432, the MCU power consumption is low, the wireless transceiver chip transmission is distance. Describing the theory of water meter, hardware framework, software idea, procedure of remote transmission and receiving. Experimental results show that within a kilometer＇s distance, the transmission rate is lower than 100 Kpbs, it can achieve the integrity of the data transmission and the steps of the charging function. The water meter has well characteristics, including the costs is low, power consumption is low, preventing water is well, it＇s the trend of intelligent water meter.
