Description

Lake eutrophication monitoring system platform based on wireless sense network
Technical field
The invention belongs to the environmental monitoring field, particularly a kind of lake eutrophication monitoring system platform based on wireless network.
Background technology
The lake is one of important drinking water source of China's urban population; in May, 2007 Wuxi City the TAIHU LAKE contamination accident to highlight China's lake coming crisis in Western sociology particularly serious, obtain comprehensively that the potable water lake is comprehensive, all the period of time, many-sided lake data be significant with early warning for the lake monitoring.
Developed country's lake pollution incident seldom occurs in the world, therefore the work of being done about the lake monitoring mainly concentrates on the influence to contiguous lake environment such as large-engineering, large industrial enterprise, nuclear power station, supervisory system often concentrates on the monitoring of a small number of parameters and analytically, or at the single technology of a certain particular problem, as remote sensing and on-line monitoring technique, the tap water PROCESS FOR TREATMENT technology etc. of water quality, used technology, platform, system are all very limited.
China is at present for the main limited means such as satellite remote sensing, aircraft remote sensing, manual method that rely on of lake monitoring, the information that satellite remote sensing, aircraft remote sensing are obtained is very limited, though artificial sampling observation can be obtained the firsthand data, but spent energy is very huge, and the data of obtaining are very limited, set up very difficulty of lake data variation model, it is then difficult more to reach prediction.
Monitoring for environment in the past relies on sensor information in a large number, and sensor information is collateral information, and limited parameter can not reflect the truth of lake parameter comprehensively.The information that satellite remote sensing is obtained is very limited, can only obtain few peripheral parameter, and is easy to be subjected to the weather restriction; The data that aircraft remote sensing obtains are more detailed than satellite, all need a large amount of co-ordinations but obtain data at every turn, and expense is very expensive; The manual method sampling number is very limited, takes water sample to go back to the laboratory in the lake and analyzes, and usually needs could obtain data for a long time, simultaneously, is difficult on the space of many ranges and observes many processes that take place and phenomenon on the different time yardstick.
Along with various on-line detector devices, sensor technology, computer technology rapid development, online detection has become possibility.On-line monitoring has directly, true, advantage such as data are abundant, real-time, also is one of the most reliable monitoring means.On-line monitoring technique and high resolving power, high spectrum, multipolarization remotely-sensed data combine, can improve the Quantitative Monitoring of water environment and the authenticity and the reliability of bioprocess greatly, this multi-source heterogeneous data are monitored in real time, have realized many data and the phenomenons that can't obtain in traditional monitoring method in the past.
Domesticly at present built up a collection of automatic water quality monitoring station in succession at the main water head site in the important section of some great rivers and important city, flume etc., but also be in the initial stage of development at present, not enough in aspect researchs such as the wireless transmission of data and follow-up data processing, modeling calculating, thereby still can't reach the requirement of early warning.
In fact the same for the monitoring of the monitoring of lake water quality and other environment, single or several observation methods are difficult to obtain results very reliably, the multiple means result that easier acquisition is trusted that combines.Remote sensing has broad perspectives and of overall importance, and on-line monitoring has microcosmic and substantivity, and these two kinds of means are combined, and has complementary advantages, and the development unified platform is realized lake observation and water quality prediction.
