Water surface oil spill monitoring system and method based on AIS navigation mark

Abstract

The invention discloses a water surface oil spill monitoring system and method based on an AIS navigation mark. The system comprises an image acquisition part, a preliminary screening part, a feature extraction part, an oil spill analysis part and a wireless communication part. According to the invention, a plurality of navigation mark node devices are manually arranged in the same water area by additionally arranging the CCD camera, so that large-range and all-weather water surface oil spill monitoring is realized, and the defect that the traditional fixed detection is influenced by a fixed object is overcome; oil spill is identified and detected through the neural network, and automatic, large-scale and high-precision oil spill monitoring is realized; meanwhile, in terms of daily maintenance and terminal communication of the navigation mark, the monitoring system is built on the AIS navigation mark, so that high management efficiency and low maintenance cost in terms of wireless signal transmission, telemetering and remote control of the monitoring system, real-time monitoring and daily maintenance can be achieved. The system and method are widely applied to the field of inland water area monitoring.

Description

technical field [0001] The invention relates to the field of inland waters monitoring, in particular to a water surface oil spill monitoring system. Background technique [0002] In recent years, with the rapid development of my country's shipping industry, more and more pollution has been caused by ship water traffic accidents and other water operations, which have caused very serious pollution to inland water resources. Actions to protect water resources are imperative . Oil spill pollution is one of the main pollutions of inland river pollution. The increase of ship density increases the traffic flow of inland rivers, and the probability of oil spill pollution accidents from inland river vessels also increases. Oil spill pollution will cause serious adverse effects on the ecological environment of inland rivers. The aromatic compounds in the oil spill will not only affect the growth of fish and aquatic plants in the water, but the polluted water source will also directly ...

AI Technical Summary

Problems solved by technology

Satellite remote sensing monitoring can realize real-time oil spill monitoring, but the spatial resolution of satellite monitoring is low, the pictures taken are not easy to identify, and the number of satellites that can be used to monitor oil spills is small

Aerial monitoring mainly uses aircraft such as airplanes or drones to carry oil spill sensors for monitoring. The monitoring accuracy is very high, but affected by weather factors and water environment, when there is bad weather and in narrow waters, aerial monitoring methods are difficult to achieve

Patrol boat monitoring is very maneuverable and less affected by weather factors, but patrol boats need to be manually controlled, and are affected by people's work and rest, so it is difficult to monitor at night

Fixed monitoring mainly installs oil spill sensors on fixed objects such as lighthouses, bridges and docks to achieve all-weather monitoring of oil spills in a certain area. The impact of the monitoring area will be greatly limited
