Nuclear power plant water intake sea area threat intelligent monitoring and early warning system

The invention provides an intelligent monitoring and early warning system for nuclear power plant water intake sea area threats. The intelligent monitoring and early warning system comprises an acquisition module, a data synchronization module, a data preprocessing module, a database module, a man-machine interface module, an algorithm scheduling module interacting with the database module and an algorithm module. Wherein the data acquisition module comprises a sonar data acquisition module, a sea power data acquisition module and a video monitoring data acquisition module. The algorithm module comprises an early warning algorithm unit based on mechanism analysis, the degree that the water intake of the nuclear power plant is blocked by marine organisms is quantitatively obtained in real time, the activity range and scene of the underwater marine organisms are subjected to cross comparison in real time in combination with a display image acquired by a video, and early warning is conducted on the threat of the
