(1) utilize solar battery group that sun power is converted to electric energy at fine day and be stored in battery pack; At cloudy day or night, then aerogenerator is relied on to be that power storage is in battery pack by Wind resource change; Battery pack is then the power source of data acquisition device system and data transmission system;
(2) video image of the water surface in camera collection radius 1 km is utilized; Then glow the existing feature causing water body to turn black according to lake, will water colour extracting change information be occurred by the plug-in of data transmission system in image and be transferred to data center;
(3) for the general feature in lake, screen general to lake relevant, that cost performance is higher and the parameter that field unattended measures can be realized, and utilize meteorological sensor, hydrology sensor, water quality sensor, some water temperatures and dissolved oxygen sensor and these water quality parameters of the real-time high frequency recording of camera, with the form of data stream, be transferred to data center by data transmission system;
(4) Various types of data that data center collects stores in a database, and provides lake general relevant information by client software to all types of user,
Chlorophyll a, algae density, turbidity, pH, the oxidation-reduction potential parameter of m place, wherein said water quality sensor record underwater 1 water quality, described some water temperatures and dissolved oxygen sensor record survey table, in and the dissolved oxygen DO of the three layers of water body in the end and water temperature parameters, the flow velocity in described hydrology sensor record platform waters and wave parameter, water colour change in described camera record platform periphery 1 km, described meteorological sensor record wind speed, wind direction, temperature, air pressure, relative humidity, precipitation parameter, the data collection interval of above-mentioned instrument is all set to 15 min.
