【摘要】：工业技术的大力发展,带来了一个突出的问题是环境污染。水环境和人类接触极其频繁,为保护其免受污染而避免造成不良后果,应运用先进的技术和方法对水环境全天候实时监测。环保部门可通进监测数据对环境污染程度度量、决策与管理,同时也通过环境执法手段来保护环境,真正使部门在环境监测和保护方面发挥重要的作用。考虑水环境监测的具体要求,结合环保部门提出的污染设备设施运行状况实时监测网络系统建设要求,本论文完成的主要工作包括:(1)以通用性好、组网灵活、成本低廉为基础,规划了水环境PH值远程自动监测系统的框架结构和各组成部分的功能设计;(2)利用低功耗、高性能的PIC18F452单片机结合PH值传感器开发了可进行现场数据采集、传输、存储、显示的仪表;节约了系统成本,易于实现环保部门大面积采用;(3)以Delphi 7为软件开发工具,结合使用JavaScript脚本调用百度地图以实现部分地理信息系统功能和Microsoft SQL Server 2008数据库平台在数据库方面的强大功能,开发了水质监测中心管理软件;该软件能通过有线或无线方式对现场设备数据进行采集,以供环保部门分析和决策;(4)水质监测中心的上位机管理软件可与现场数据采集终端设备进行通讯,既可以接收现场采集数据,也可发送命令对现场PH值数据采集终端设备进行控制和管理。本论文所述的水环境PH值远程自动监测系统方案已初步实施,并在太原市环保部门管理的一定范围内投入使用。现场采集终端设备通过在现场实际运行,性能稳定、记录数据准确、容错性好、故障率低;监测中心软件功能强大、交互性好、使用方便,较好地实现了系统初期规划要达到的目标,也为以后系统的进一步完善和升级奠定了基础。
[Abstract]:With the development of industrial technology, a prominent problem is environmental pollution.Water environment and human contact are very frequent. In order to protect water environment from pollution and avoid adverse consequences, advanced technology and methods should be used to monitor the water environment in real time around the clock.Environmental protection departments can use monitoring data to measure, make decisions and manage environmental pollution. At the same time, environmental protection departments can play an important role in environmental monitoring and protection by means of environmental law enforcement.Considering the specific requirements of water environment monitoring, combined with the requirements of the environmental protection department for the construction of real-time monitoring network system for the operation of pollution equipment and facilities, the main work accomplished in this paper includes: (1) on the basis of good generality, flexible networking and low cost,The frame structure of the water environment PH remote automatic monitoring system and the function design of each component are planned. The low power consumption, high performance PIC18F452 single chip computer and PH sensor are used to develop the field data acquisition, transmission and storage.Delphi 7 is used as a software development tool.Combined with the use of JavaScript script to call Baidu map to realize part of the GIS function and the powerful function of Microsoft SQL Server 2008 database platform in database, the management software of water quality monitoring center is developed.The software can collect the data of the field equipment by wired or wireless way, so as to provide the environmental protection department with analysis and decision. 4) the upper computer management software of the water quality monitoring center can communicate with the terminal equipment of the field data acquisition.It can not only receive the data collected on the spot, but also send commands to control and manage the terminal equipment of PH value data acquisition in the field.The scheme of the water environment PH remote automatic monitoring system described in this paper has been implemented preliminarily and put into use within a certain range of the management of Taiyuan environmental protection department.The field acquisition terminal equipment is stable in performance, accurate in recording data, good in fault tolerance, low in failure rate, powerful in function, good in interactivity and convenient in use.The goal of the initial planning of the system is well realized, and the foundation is laid for the further improvement and upgrading of the system in the future.
