摘要

 現(xiàn)行的預(yù)付費(fèi)水表多為卡式水表，其在應(yīng)用中存在著一定的不足之處。這里利用紅外遙控技術(shù)設(shè)計(jì)了一種新型水表，既實(shí)現(xiàn)了預(yù)付費(fèi)水表的功能，又可避免卡式水表在應(yīng)用中的缺陷。
 整個(gè)系統(tǒng)中主要包括：水表系統(tǒng)硬件部分，如紅外通訊電路，電源模塊，水表計(jì)量電路，PC 機(jī)讀寫器電路等；水表系統(tǒng)的軟件設(shè)計(jì)和軟件抗干擾；紅外通信協(xié)議和通信加密技術(shù)；數(shù)據(jù)庫(kù)系統(tǒng)管理軟件設(shè)計(jì)等。此外還包括硬件抗干擾，紅外通信抗干擾，水表線性標(biāo)定等內(nèi)容。
 本文主要介紹了紅外預(yù)付費(fèi)水表應(yīng)用系統(tǒng)的概念，結(jié)構(gòu)以及功能等內(nèi)容。其中最主要闡述了終端系統(tǒng)與通訊系統(tǒng)單片機(jī)控制模塊的設(shè)計(jì)流程，包括16位低功耗430單片機(jī)的介紹，紅外通訊電路，軟件設(shè)計(jì)等內(nèi)容。

ABSTRACT

 Currently the prepaid water meters are mainly card style that is deficient in applying . Making use of infrared remote control technology , a new water meter is designed which can not only realize all the functions of prepaid water meter but also avoid the limitation of card style water meter .
  The main contents of this thesis are as follows : the hardware of water meter system such as the circuit of infrared communication , the power module , the metric circuit , the read-write implement of PC etc ; the software design and interference resisting ; infrared communication protocol and encryption techniques ; the design of the database management system . In addition the hardware interference resisting , infrared communication interference resisting and the linear demarcation of water meter are included in this thesis also .
 This paper mainly introduces the concept , structure and function of the application system of prepaid water meter. The paper illustrates the design flow of the terminal system and the communication system of monolithic integrated circuit control module, which contains the introduction of the 16 low power losses monolithic integrated circuits, and such contents as the circuit of infrared communication and the design of software.

 Keywords: Prepaid water meter, Circuit of infrared communication, Software design
