Water pollution source rapid tracing method and system based on molecular communication mechanism

Abstract

The invention discloses a water pollution source rapid tracing method and system based on a molecular communication mechanism. The method comprises the following steps: randomly arranging four water quality sensor terminals in water; initializing diffusion coefficients of pollution source molecules corresponding to the related water quality indexes in water; acquiring readings of related water quality indexes of the sensor terminals, acquiring position coordinates of the sensor terminals by positioning modules arranged in the sensor terminals, and uploading the position coordinates to a computer through a wireless module; and after the computer receives the related water quality index readings and the position coordinate information of the water quality sensors, establishing and solving asimultaneous equation system about the pollution source coordinates, diffusion time and the number of molecules released by the pollution source based on a concentration diffusion formula so as to obtain the position coordinate information of the pollution source, the number of molecules released by the pollution source and the diffusion duration of the pollution source. Compared with the prior art, the method can quickly and accurately locate the position of the pollution source and obtain the related information of the pollution source, and is excellent in performance and easy to implement.

Description

technical field [0001] The invention relates to the field of traceability of water pollution sources, in particular to a method and system for rapid traceability of water pollution sources based on a molecular communication mechanism. Background technique [0002] At present, the river chief system is fully implemented across the country. In view of the implementation of the six major tasks of the river chief system: "water resource protection, river and lake shoreline management and protection, water pollution prevention and control, water environment governance, water ecological restoration, law enforcement and supervision", the auxiliary role of information construction is urgently needed. Among them, water quality monitoring is directly related to people's livelihood issues. Traditional water quality monitoring methods are mainly divided into two types: one is for high-frequency monitoring of drinking water, industrial waste, sewage, etc., mainly based on laboratory tes...
