Abstract: This article make full use of the position function of BeiDou Satelites Navigat System under the background of large data. The positioning function, using unmanned ships as the client, actively explores new practice solutions in the issue of water quality data collection and source location, and quickly and accurately finds the source of pollution, reduce the time of river pollution, and no one on board has the corresponding purification module, do some simple treatment when found pollution. The water quality analyzer is installed on unmanned ships, and the BeiDou satellite positioning chip, WiFi data transmitter, is waterproof processed in the transmission module of the water quality analyzer. The types and concentrations of pollutants in rivers are analyzed, and the location of pollution sources is calculated using the calculation method of large data, and the results of pollution source analysis and pollutant treatment methods are reflected in the cloud platform. Through the BeiDou Satellite Navigation System, these data are divided into locations and the shortest route to the source of pollution is sent to the processing person's mobile device. This paper analyzes the visual system of water pollution monitoring based on BeiDou satellite positioning in order to find out the pollution sources quickly and reduce the water pollution.
