The Research And Development Of On-line Environmental Monitoring Information System

As the resource of date, measurement of pollution, foundation of environmental decision and management, as well as the component of environmental enforcing law, environmental monitoring plays an important role in environmental protect. With the progress of science and technology, the means, methods and management level of environmental monitoring has improved continually while the global environmental problem has increasingly outstood and environmental protect has flourished. The most effective way and its tendency t are on-line management and treatment to monitoring business applying information technology at present.Based on the summarized later experience and the developing tendency of on-line environmental monitoring home and abroad, it is discussed that environmental monitoring combines with information technology including to automatic control, data base, Geographic Information System and network communication, at same time an advanced and feasible on-line pollution resource monitoring information system in Guangzhou has designed in this paper.The data collecting machine is key part of the system, and it can accomplish the data collecting and long-distance supervision to environmental elements such as pollution resource according to field date's automatic collecting and transmission, automatic alarm and long-distance control of center station; the up-to-date wireless communication is adopted in the system, it breaks through traditional wire communication and has the advantages of large-quantity transmission, safety, high efficiency and small cost; The perfect and adoptable application software of the system is developed utilizing date management software of Oracle, it takes monitoring process flow as main line and almost contains all business of pollution resource monitoring; It is discussed that Geographic Information System applies to on-line environmental monitoring system. Some functions such as data inquiring, statistics, environmental chartingand showing as well as environmental assess, prediction, disaster relief, scheme and management on base of geographic information can be accomplished in aid of the system. The system is suitable for not only on-line pollution resource monitoring but also all long-distance real time impersonal monitoring system.It will improve the theoretical research and practical construction level of on-line environmental monitoring system in Guangzhou as well as our country according to this system, and it will also provide certain theoretical and practical reference to application and popularization of on-line environmental monitoring in China.
