大型储水罐 多点水位遥测与控制系统 The Large-scale Water can Multi-spots Water Telemetering and Control System 摘 要 目前，我们的水资源已经相当的紧缺，已经引起全社会的关注。如何节约用水，有计划地用水已成为社会的一个重要课题。 在新世纪，水利作为国民经济基础设施和基础产业，必须运用现代科技手段，获取实时、准确的水利信息，才能促进工程水利向资源水利、传统水利向现代水利的转变，以适应时代对水利行业的要求。随着信息技术和测控技术的发展，水文遥测系统越来越完善，同时单片机广泛地应用与水文的遥测系统中，如测站、控制站、中心站等。 本次大型储水罐多点水位遥测与控制系统，其核心是利用GSM短消息系统为通讯载体，对测量端获得的数据进行分析处理，并将处理的结果发送给控制系统，最终达到遥测与控制的目的。其设计主要内容有：水位数据采集系统的设计、数据收发系统的设计、PLC控制系统的设计。 本次设计的基本思路是：利用传感器采集水位数据，通过数据的收发系统，将采集的数据发送给用户端；用户端根据水位报表的反映，调用相应的水位控制程序，将程序发送给远程的控制系统（PLC），实现水位的监测与控制。 关键词：GSM短消息 遥测 水位数据采集 PLC Abstract At present, our water resources already the suitable scarcity, alreadyaroused the entire societys interest. How saves the water used, hasthe plan water used to become social an important topic. In the new century, the water conservation took the national economyinfrastructure and the foundation industry, must utilize the modernscience and technology method. Real-time gains, the accurate waterconservation information, can promote the project water conservationto the resources water conservation, the traditional waterconservation to the modern water conservation transformation, adaptsthe time to the water conservation profession request. Along with theinformation technology and the observation and control technologydevelopment, hydrology telemetry system more consummates,simultaneously the monolithic integrated circuit widely applies and inthe hydrology telemetry system, like survey station, control station,central station and so on. This large-scale stores the watering can multi- spots water leveltelemetering and the control system, its core is uses the GSM short newssystem is the communication carrier, obtains the data through thesurvey end to carry on analysis processing, and will process theresult transmission for the control system, finally will achieve thetelemetering and the control goal. Its design main content includes:Water level data acquisition system design, data receiving a
