基于MSP430单片机的水表设计毕业设计.doc

[摘要] 随着我国城镇建设的快速发展，有关城市的水表的管理和抄表出现的问题也日益严重，根据自来水表的改造、小区的建设以及实施“一户一表”工程的需要，本文设计了一种基于MSP430单片机的远程集中抄表系统及数字式网络水表，数字网络水表通过集中器和上位机管理系统连接，将水表的数据传输给远方的上位机，同时上位机管理系统通过集中器对网络水表进行监测和管理。针对传统旧式水表存在的各种缺陷，本文介绍了目前市场上出现的各种水表，在大量收集和查阅国内外有关资料，以及深入的调查实践，提出了一种低功耗的脉冲水表，这种水表以MSP430单片机为核心，采用了“双控”传感器检测方法，实现了用户用水量的采集、计量、处理、存储等，克服了传统旧式水表的存在的偷水、漏水等缺陷。主要完成了远程集中抄表系统的功能设计，对水表的各个组成部分的硬件的选择和软件设计突出了稳定性和低功耗；对远程集中抄表系统的设计突出了数据传输的可靠性，增加了传输距离，解决了挨家挨户的抄表问题。 [关键词] MSP430单片机；“双控”传感器；数据采集；低功耗。 Abstract : with the rapid development of urban construction in our country,the city of the management of the water meter,and the problem is increasingly serious,according to the water meter of the transformation ,the construction of the community as well as the implementation of one household one table engineering need,Aimed at various defects existing in the traditional water meter ,this paper introduces all kinds of water meter on the market at present,in a large collection of and access to relevant information both at home and abroad ,and in-depth investigation and practic,this paper proposes a low power pules meter,the meter with MSP430 single chip microcomputer as the core, Adopted the double control sensor detection method ,realizing the collection of water users,measurement,processing,storage,etc.,to overcome the existence of traditional water meter to steal water,leakage and other defects .Mainly to complete the function of remote concentrated meter reading system design,choice of water meter all parts of the hardware and software design highlights the stability and low power consumption;To the design of remote concentrated meter reading system highlights the reliability of data transmission,increased the transmission distance,solved the reliability of data transmission,increased the transmission distance,solved the problems of door-to-door meter reading. Keyword: MSP430 single chip microcomputer,low power consumption,double control sensor, data acquisition. 目录 1 绪论 1 1.1 本课题的研究意义及必要性 1 1.2 相关
