A method for automatic detection of water pollution sources

Abstract

The invention discloses an automatic detection method for a pollution source in a water area, and the method employs a controller, a drive unit, a sampling device, an azimuth sensor and water quality sensors, wherein the drive unit, the sampling device, the azimuth sensor and the water quality sensors are controlled by the controller. The method comprises the steps: (1), setting a contaminant detection threshold value S0; (2), enabling the plurality of water quality sensors to collect the pollutant concentration simultaneously at the time interval delta T, and comparing the maximum value S of the data with S0: enabling a detection device to continue to move forward in an initial direction when S is not greater than S0, or else, enabling the detection device to move forward in a direction of the water quality sensor corresponding to the maximum value S till to reach the area where the pollution source is located. The method can carry out automatic cruising, automatic positioning and unmanned operation in the water region, can automatically search the position of the pollution source in the water area, and can bring back a sample. The method can reach a water region which cannot be reached by a person, or a water region with a big danger. The method can automatically monitor the condition of the water quality of a large-area water area in real time, and obtains the specific pollutant concentration of the water area.

Description

technical field [0001] The invention belongs to the field of water quality detection in water areas, and more specifically relates to an automatic detection method for water area pollution sources. Background technique [0002] With the continuous acceleration of industrialization and urbanization, water pollution incidents are increasing, which has brought serious damage to the daily life of the people and the sustainable development of human society. Therefore, it is urgent to increase the protection of water sources and the punishment of water pollution. At present, there are serious illegal activities such as privately setting up hidden pipes to secretly discharge, or using hoses to directly discharge or dilute the discharge. If the location of the pollutants in the river cannot be determined, the pollutant leakage will undoubtedly become more and more serious over time. [0003] Chemical wastewater contains a large amount of toxic and harmful substances. Although the ...
