The high blue algae monitoring early warning system based on unmanned plane of precision.
Background technology
Water quality is monitored in real time as the monitoring net of an entirety using lake, river, river, is that prevention is illegal, arranges in violation of rules and regulations
Put sewage, administer water pollution in time, and early warning in time and suppress the water plant of fast-growth such as blue-green algae effective means it
One.
Each department lake monitors and early warning blue-green algae because the amount reproduction of blue-green algae causes the event of water pollution to take place frequently
Excessive multiplication have the ecological balance safeguarded around lake be significant.
The monitoring method that test point is most original is set up at the blue-green algae ground scene that takes place frequently, but due to being based on personal monitoring,
It is often not prompt enough and accurate.In addition, satellite remote sensing technology monitoring also gradually grows up in recent years, satellite remote sensing technology is utilized
Monitoring blue-green algae has instantaneity and broad perspectives, but the resolution ratio of satellite remote sensing technology and accuracy need to be improved, moreover, such as
Fruit runs into bad weather, and because visible ray and infrared ray are interfered, the degree of accuracy of satellite remote sensing technology can substantially reduce.And this
Millimeter wave remote sensing has performance all-time anf all-weather used by text, can not be influenceed by boisterous, obtains visible ray
The specific information that can not be obtained with infrared detector.
So remote sensing monitoring and unmanned plane monitoring mode are mainly used to large area region water pollution monitoring.
