River way multi-sensor fusion upstream and downstream pollution early warning system and method

Abstract

The invention discloses a river way multi-sensor fusion upstream and downstream pollution early warning system and method. A river way part includes a water quality on-line monitoring buoy nodes deployed on multiple parts of the upstream and the downstream of a river way, and a shore part includes a wireless gateway and a cloud server. The water quality on-line monitoring buoy nodes are used for real-time collection, storage and transmission of water quality data; the system includes a water quality multi-sensor system, a water flow sensor, a real-time clock module, a microprocessor, a wireless communication module, an antenna, a storage module and a power source module. A river way multi-sensor data fusion analysis model is established by the cloud server, the multi-sensor data fusion method is used for analyzing whether the pollution exists in the river way, classifying pollutants and estimating the location of a pollution source, the upstream and downstream relations are combined for on-line monitoring and classified early warning on the river way water quality, whether the river way is invaded by the pollutants is judged, and the location of the pollution source is estimated. The system and the method perform on-line monitoring by multiple water quality parameters, and have the advantages of low energy consumption, high detection rate of the pollutants and wide applicationrange.

Description

technical field [0001] The invention relates to a water quality early warning system, more specifically, to a multi-sensor fusion upstream and downstream pollution early warning system and method for a river channel. Background technique [0002] At present, the problem of water pollution has become increasingly prominent, seriously affecting the safety of drinking water for urban and rural residents, and urban water supply was once in short supply. As people pay more and more attention to the health of water quality, the research on water quality safety monitoring has become a widely concerned research field. Water quality health monitoring can monitor water source protection areas and reservoirs in real time through sensors. It can also organize and analyze the collected data, establish corresponding mathematical models, and provide guidance for daily water quality management, thereby improving all aspects of water quality management. Alarms are issued for major water qua...

AI Technical Summary

Problems solved by technology

First, the sampling frequency of water quality monitoring centers at each level is low; second, the number of online monitoring stations is too small, and the on-site monitoring capabilities are low, so it is impossible to obtain real-time parameter information of water quality in important water source areas
