【摘要】：随着我国工业化水平的不断提高，企业在创造物质财富和提高人民生活水平的同时也正在污染我们赖以生存的自然环境。其中水的污染正日趋严重，不但河流和湖泊等地表水的水质在恶化，作为重要饮用水源的地下水质也在变差。日趋严重的水污染正威胁到人们的健康和整个社会的可持续发展。水污染的严峻形势迫使人们增加对水污染监测的重视程度和加强污水治理力度。但是要加大对污水排放的监管力度需要建设大量的水质监测站，当前常规的污水在线监测系统由于其建设成本较高因此很难大规模推广。针对这个问题，本论文从降低成本和保证在线检测数据的可靠性着手，兼顾系统对数据的采集和管理，利用嵌入式技术，设计开发了基于S3C2440微处理器和嵌入式Linux操作系统的污水在线检测管理系统。利用MiniGUI图形界面和触摸显示屏，实现了系统的人机交互；利用S3C2440微处理器丰富的外围接口，完成了基于SPI总线的ADC的数据采集和单色仪驱动，从而实现了基于分光光度法的水质氨氮检测；利用嵌入式系统中的网络控制芯片，实现了监测系统和远程服务器的数据传输。本论文详细描述了系统的开发流程和关键技术的实现方法，最后在实验室条件下对系统进行了测试，工作稳定，，达到预期的设计目标。本污水在线检测管理系统的应用和推广，在保证可靠性的同时，降低了建设成本，将带来良好的社会效益和经济效益。
[Abstract]:With the development of industrialization in our country, enterprises are polluting the natural environment on which we depend while creating material wealth and improving people's living standard. Among them, the pollution of water is becoming more and more serious. Not only the water quality of surface water such as rivers and lakes is deteriorating, but also the underground water quality, which is an important source of drinking water, is becoming worse. The worsening water pollution is threatening the health of people and the sustainable development of the whole society. The severe situation of water pollution forces people to pay more attention to water pollution monitoring and strengthen sewage treatment. But to strengthen the supervision of sewage discharge, a large number of water quality monitoring stations are needed. It is difficult to popularize the conventional sewage on-line monitoring system because of its high construction cost. In order to solve this problem, this paper starts with reducing the cost and ensuring the reliability of the on-line inspection data, taking into account the data collection and management of the system. Based on the embedded technology, a sewage on-line detection and management system based on S3C2440 microprocessor and embedded Linux operating system is designed and developed. The man-machine interaction of the system is realized by using the MiniGUI graphical interface and touch display screen. Using the rich peripheral interface of S3C2440 microprocessor, the data acquisition and Monochromator drive of ADC based on SPI bus are completed, and the water quality ammonia nitrogen detection based on spectrophotometry is realized, and the network control chip in embedded system is used. This paper describes the development process of the system and the implementation of the key technologies in detail. Finally, the system is tested under the laboratory conditions, and the work is stable. Achieve the desired design goals. The application and popularization of the sewage on-line inspection and management system can not only guarantee the reliability but also reduce the construction cost and bring good social and economic benefits.
