水质监测系统的软件设计

水质监测系统的控制软件设计摘要水是生命的源泉、农业的命脉、工业的血液。哪里有水，哪里就有生命，一切生命活动都是起源于水。但随着全球工业生产的发展和社会经济的繁荣，大量的工业废水和城市生活废水排入水体，水体污染日益严重。多年来，我国水资源质量不断下降，水环境持续恶化，由于污染所导致的缺水和事故不断发生，不仅使工厂停产、农业减产甚至绝收，而且造成了不良的社会影响和较大的经济损失，严重地威胁了社会的可持续发展，威胁了人类的生存。由于水体污染严重并且已经对人类的生活生成了威胁，所以不得不采取各种各样的方法来进行水体监测。目前的检测设备主要依赖于实验室的大型设备，这些设备体积庞大，检测时间长，分析时会消耗大量的化学试剂，价格昂贵。当然随着技术的发展，慢慢开始出现一些小型的检测设备，主要是依据光学以及流量检测的方法来检测，最典型的就是传感器探头以及GPRS探头检测。利用网络技术、环境监测技术、自动控制技术和计算机技术，设计开发先进的“水质监测控制系统”是现代环境信息管理的需要，本文以中国现状的水质情况以依托，进行水质监测控制系统的软件系统设计。本文介绍的水质监测的控制系统软件是基于光学智能分析水后，从测量的光谱信号中提取有关污染物含量的所有信息，再经过A/D转换成数字信号，经过单片机转换成有用的数据存储成数据。然后用该软件时行数据接收、显示、统计、自动综合分析、存储、应用、发布等，并实现远程的监控。关键词：水质监测系统、水质检测、软件设计、控制软件系统设计ControlsoftwaredesignofwaterqualitymonitoringsystemABSTRACTWateristhesourceoflife,thelifebloodofagriculture,industryblood.Wherethereiswater,thereislife,alllifeactivitiesareoriginatedinthewater.Butwiththedevelopmentofglobalindustrialproductionandsocio-economicprosperity,alargenumberofindustrialwastewaterandurbandomesticwastewaterdischargedintowaterbodies,waterpollutionisgettingworse.Overtheyears,thedecliningqualityofwaterresources,waterenvironmentcontinuedtodeteriorate,duetopollutionandaccidentscausedbywatershortagescontinuetooccur,notonlyfactoriesclosedandagriculturalproductionorcrops,andresultedinadversesocialimpactsandthelargereconomyloss,aseriousthreattothesustainabledevelopmentofsocietyandthreatenthesurvivalofhumanity.Sincewaterpollutionisseriousandhasalreadygeneratedathreattohumanlife,wehadtotakeavarietyofmethodsforwatermonitoring.Thecurrenttestingequipmentmainlydependsonlarge-scalelaboratoryequipment,thesedevicestrapvolume,testingtimeislong,andtheanalysiswillconsumealargeamountofchemicalreagentsandexpensive.Ofcourse,astechnologyevolves,someminortestingequipmentslowlybegantoappear,itbasedontheopticalandflowdetectionmethods,themosttypicalsensorprobeandprobedetectionistheGPRS.Asnetworktechnology,environmentalmonitoringtechnology,automaticcontroltechnologyandcomputertechnologyputintouse,designanddevelopmentofadvancedWaterQualityMonitoringSystemisamodernenvironmentalinformationmanagementneeds,thispaperissupportedtothestatusofwaterqualityinChina,anddesignthecontrolsoftwareofwaterqualitymonitoringsystem.Thisarticledescribesthewaterqualitymonitoringofthecontrolsystemsoftwareisbasedonintelligentanalysisoftheopticalwater,thenspectralsignalfromthemeasurementtoextractalltheinformationaboutcontaminants,andthenthroughtheA/Dconvertedintodigitalsignals,afterconversionintousefulsingledatastorageintothedatachip.Andthenusethesoftwaretolineofdatareception,display,statistics,autocomprehensiveanalysis,storage,application,release,etc.,andremotemonitoring.KEYWORDS:WaterQualityMonitoringSystem、Waterqualitytesting、SoftwareDesign、Controlsoftwaresystemdesign目录摘要ABSTRACT第1章绪论.................................................11.1水质监测的意义.....................................................................................11.1.1中国水环境的现状......................................................................11.1.2水体污染来源..............................................................................11.1.3水质监测的意义..........................................................................21.2水质滥测的现状.....................................................................................21.3水环境监测的发展趋势.........................................................................31.4论文研究的内容和目标.........................................................................41.4.1论文研究内容..............................................................................41.4.2论文研究目标..............................................................................4第二章水质监测系统的控制软件结构设计...........................52.1水质监测系统的控制软件设计规划.....................................................52.1.1系统化的设计思想......................................................................52.1.2软件的结构化体系......................................................................62.2水质监测系统的控制软件功能分析.....................................................72.2.1现场自动监测系统的控制功能..................................................72.2.2远程管理中心监测控制系统功能............................................10第三章水质监测系统的控制软件设计..............................113.1软件开发的基本原则............................................................................113.2程序设计方法........................................................................................113.3软件的需求分析...................................................................................123.3.1运行环境需求............................................................................133.3.2可靠性需求................................................................................133.3.4数据管理能力需求....................................................................133.3.5编程语言的选择........................................................................133.4.1前台人机交互程序的总体设计................................................153.4.2后台运行程序总体设计............................................................163.5水质监测系统的控制软件功能模块设计...........................................173.5.1初始化模块............................
