Research On CEMS Based On WEB Interaction Technology

With the increasing prominence of the global environmental issues and environmental protection, the environmental monitoring technology based on chemical analysis and testing has become a multi-disciplinary and comprehensive science. Web-based on-line monitoring system, which responses to the development of the monitoring technology, progresses step by step. It is designed to replace the traditional C / S mode, construct a real continuous real-time remote monitoring system and realize the remote automatic data transmission. It also aims to integrate data inquiry, data Statistical analysis, remote monitoring, electronic geographic information, intelligent decision-making and business disposal as well as to test the integrality and validity of the data automatically.Grounded on the research of the defects of the traditional on-line monitoring system and the future demand of monitoring, the author proposes the notion of web-based continuous real-time on-line pollutant source monitoring system, which characterized by real time, continuity, openness and convenience. First of all, the thesis designs the overall framework of the system through analyzing the features of the on-line monitoring system and its functional requirement, which aims to perfect to function of every frame layer and to enable the layer to keep independent while working coherently and harmoniously. Secondly, the thesis emphasizes the analysis of the application of Web, including optimizing the design of database according to the mass data accumulation, designing the class in the system which needs to be frequently invoked independently and partitioning the function of Web application in order to make become independent subsystem. At last, the thesis analyzes the characteristics and advantages of relevant technology aiming at the thinning of subsystem and selects appropriate technology to realize every subsystem which eventually leads to the complete on-line monitoring web platform. Web-based on-line monitoring system is a great renovation compared with the traditional monitoring measure, which enables the customers that distributes everywhere can obtain the data of on-the-spot monitoring easily through the browser. It eliminates the inconvenience of the administrators caused by the restriction of time and place.Guaranteed by data integrality and validity, this system realizes the real-time continuous data collection in an unmanned environment on the condition of data, which provides precise and complete data for environmental monitoring. Meanwhile, as an integrated central platform, web-based on-line monitoring plays a more and more important role in business disposal and decision -making.
