Description

technical field [0001] The invention relates to the field of data analysis systems and analysis methods, in particular to a machine learning-based fog monitoring system for cross-sea bridges and an application method thereof. Background technique [0002] The sea-crossing bridge has brought great convenience to the travel of coastal people, but because of the high cost of the sea-crossing bridge, it needs a high enough traffic volume to effectively recover the cost, and the sea-crossing bridge requires a higher level of traffic than conventional roads security. Heavy fog (or dense fog) is one of the more common disastrous weathers that affect traffic. It has the characteristics of high probability of occurrence, wide range of occurrence, and high degree of harm. It can be seen everywhere all year round. Its harm; in addition, due to the abundant water vapor on the sea surface and the frequent impact of cold air from the south, the sea-crossing bridge is very seriously affec...

Problems solved by technology

[0005] In order to overcome the disadvantages that the existing local area fog that occurs in the surrounding sea area of ​​the cross-sea bridge cannot be effectively and accurately predicted, and the relevant departments cannot carry out early warning and road closure control of the cross-sea bridge based on the local area fog forecast. The high-time-resolution geostationary meteorological satellites are combined with high-altitude resolution polar-orbiting meteorological satellites and bridge visibility observations, and observation data such as visibility, temperature, and relative humidity observed by surrounding weathe...
