Abstract: Embodiments of the present disclosure relate to a water area pollution intelligent monitoring and analysis method and system. The method includes: acquiring, by a receiving module of a water area pollution monitoring and analysis device, water quality data of a monitored water area; inputting, by a processing module in the water area pollution monitoring and analysis device, the water quality data into a water quality feature extraction model in the processing module to obtain water quality features of the monitored water area, where the water quality feature extraction model is previously trained; determining, by an encoding module in the water area pollution monitoring and analysis device, a state diagram of the monitored water area according to the water quality features; and sending, by a routing module in the water area pollution monitoring and analysis device, the state diagram to a preset server.

Abstract: Embodiments of the present disclosure relate to a water body pollution intelligent investigation method and device based on unmanned ships. The method includes: determining a first pollutant concentration value of a monitored water area according to water quality data of the monitored water area; controlling an unmanned ship to cruise in the monitored water area according to a preset cruise trajectory and perform water quality collection to obtain a second pollutant concentration value of the monitored water area; determining, when there is an abnormal cruise coordinate point, a target cruise trajectory according to the second pollutant concentration value of the abnormal cruise coordinate point; and controlling the unmanned ship to cruise according to the target cruise trajectory to determine a pollution source of the monitored water area.

Abstract: Embodiments of the present application relate to methods, devices, apparatuses, and storage media for monitoring and analyzing air pollution. The methods includes acquiring air quality data of a monitored area, where the air quality data includes ground air quality data corresponding to the monitored area and N-component data collected by an air sensor in the monitored area; inputting the air quality data into a pollution analysis model, where the pollution analysis model is previously trained according to the ground air quality data and the N-component data; and determining whether the air quality data of the monitored area is abnormal according to an output result of the pollution analysis model. The methods may solve the technical problem of inaccurate monitoring results caused by the susceptibility of air quality monitoring in related technologies to human intervention.
