The Research Of Monitoring Technology On Shoreline And Water Quality Of Lake Based On IOT

Lake monitoring is a hot issue in Lake ecological environment protection areas, which has wide range of social value. At present, some scientists have always researched and proposed a few of methods, that are beneficial to protect lake environment, for example Manual monitoring, Physical chemical and biological monitoring、Electronic Instruments monitoring> Lakes Satellite Remote Sensing monitoring and WSN monitoring etc.But,these have mainly researched on water quality of lake.at present,that is not a technology to monitor people behavior on Shoreline.meanwhile,that is too not a technology to monitor the water quality of entire lake by Multi-Stations.As a researcher, how to prevent lake pollution by using IOT, Wireless Sensor Network, Computer Science Technology and other high-tech, has become a hot research in China and abroad today. This paper mainly research on the control technical architecture. and location algorithm, embroidering Moving Objectors around the lake, Moving Objectors on the lake and water quality. I believe that it will have important social value for protection, construction and promotion of Lake Ecological Environment.The main research works are as follows:Firstly, this paper mainly takes 11 major lakes as research object in Hubei Wuhan, for example,East Lake, South Lake and Moshui Lake. And establishes feature model aboot pollution of Lakes in Wuhan. In 2012,2013 and 2014, through monitoring these lakes and analyzing these statistical data, it discovers that now less than 20% Lakes can reach preliminary functional categories and they have been at the level of danger in Wuhan. At the same time, the eutrophication in these lakes also is more and more high, tending to be intermediate level. The quality of lake water has showed an overall declining trend in general. We can find that pollutants, which affect water quality of lake mainly includes Total Phosphorus, Ammonia Nitrogen, Petroleum, COD, BOD, and Permanganate.They are derived from the area of people’s lives, tourism and industry. But discharge of living sewage is major factor among above fields. In addition, filling lake is the cause of lake pollution directly in Wuhan, it is also the biggest killer.Secondly, through analyzing the feature model of pollution of lake in Wuhan, this paper mainly put forward the prevention projects to protect the ecological environment of the lake from three aspects.1.Real-time remote monitoring moving objectors around the lake shoreline.Through building ZigBee wireless sensor network, it can monitor the moving objectors around the lake shore. In the processing of experiment simulation, because the sampling values about original RSSI (Received Signal Strength Indicator) are very easily influenced by different factors around the lake shore,1 propose an improved algorithm-MAF (Moving Average Filter) in this paper. Finally, I put forward LMOAL (Location of Moving Objector Around Lake) that can achieve location of monitoring moving objectors around lake shore:Firstly, in the ranging phase, establishing the relationship between Distance and RSSI function of the moving objectors, in order to set up a Database; secondly, in the location phase, according to the basic principle of the "Trilateration" method, calculating the plane coordinates of moving objectors.2.Real-time remote monitoring moving objectors on lake. By using Wi-Fi and video recognition technology, it can build Wi-Fi wireless sensor network to monitor the moving objectors on the lake, first of all, I put forward VSL (Video signal loss Algorithm) and DOE(Definition of Exception Algorithm)in this paper,in order to solve two Video Exception-video signal loss and the definition of abnormal; in the next place, I put forward LMOOL (Location of Moving Objector On Lake) that can achieve location of monitoring moving objectors on the lake, and carry on some experiments:Firstly,in the ranging phase, according to the basic principle of sonar sensor and Video Recognition, establishing the model of ranging, and calculating traveling distance of the moving target in the lake; secondly, in the location phase, according to the basic principle of the "Trilateration" method, calculating plane coordinate of the moving objectors.Finally,in order to increasing accuracy about location, I also propose 3DLA (3D Location Algorithm) based on LMOOL:Firstly, in the ranging phase, establishing the model of ranging based on 3D rectangular coordinate system, and calculating slant-range; secondly, in the location phase, calculating 3D coordinate of the moving objectors by "Trilateration" still and amending location error.3.Real-time monitoring the water quality of entire lake. At present, people in China monitors water quality of lake and other water resources, mainly by using single site status, but it cannot exactly reflect the water quality state about whole lake. I put forward a new thought MSPM (Multi-Stations Plane Monitor) that can monitor water quality of entire lake based on Multi-Stations Plane. Firstly, I design information gather&survey node in Monitor System on water quality of Lake base on WSN by Hach SC200+U53,in order to monitor lake.Secondly,in the processing of experiments simulation, I mainly use IOW wireless sensor network water quality monitoring system platform by IBM company to data management, monitoring,data analysis, data correction and data validation based on the multiple station of lake,also to evaluate the water quality by some legend and report forms, complete the real-time monitoring water quality of lake. Finally, reaserches application of monitoring technology on Lake Environment Protecting Education.All in all, by analysis and research of four aspects, including feature model about polluted Lakes in Wuhan, monitoring Moving Objectors around the lake, monitoring Moving Objectors on the lake and monitoring water quality of lake, the reaserch of application in the field of education based on IOT, I believe that it should have very positive results for protecting, construction and promotion of Lake Ecological Environment in the long term.
