Embodiment Construction

[0038] Below in conjunction with accompanying drawing, technical scheme of the present invention is described in further detail:

[0039] The invention proposes a method for tracing the source of sudden gas pollution by a wind-resistant unmanned aerial vehicle based on LS-SVM control. The drone includes an ultrasonic module, a high-definition zoom camera, a thermal infrared imaging module, and a gas detection module, such asfigure 1 shown. Among them, UAVs rely on ultrasonic modules to enable UAVs to avoid obstacles in the air during flight; high-definition zoom cameras are used to deal with sudden pollution during the day, take pictures of pollution sources, collect their geographic information and collect evidence; thermal infrared The imaging module is used to deal with sudden pollution at night, and the drone can still collect geographic information and take photos for evidence; the gas detection module contains various gas sensors to measure the concentration of flammable...

Abstract

The invention discloses a method for tracing a burst gas pollution source by using a wind resistant unmanned aerial vehicle based on LS-SVM control. Aiming at overcoming the defects of the prior art,a moving flight method for tracing the pollution source with an inclined funnel track is provided. The LS-SVM is used for tracking and controlling the inclined funnel track of the unmanned aerial vehicle, and the wind disturbance factor is taken into account. According to the invention, when the unknown pollution source is traced, considering the direct special relationship between gas pollution and wind interference, the unmanned aerial vehicle stays for 10 minutes after successfully tracing the pollution source for photographing and sampling. After that, the flight data is initialized and the pollution source is recircularly traced to improve the accuracy of positioning the pollution source and the anti-interference ability. According to the invention, the pollution source can be timelyand effectively traced, timely sampling and photographing for taking evidence can be carried out on the pollution source, follow-up remedial work of environmental supervision personnel is facilitated,the pollution source is prevented from being enlarged, and meanwhile, strong evidence is provided for the subsequent liability cognizance of the pollution.

Description

technical field [0001] The invention belongs to the technical field of automatic control track tracking, and in particular relates to a method for checking pollution sources by an unmanned aerial vehicle under the condition of wind disturbance. Background technique [0002] After the reform and opening up, a large number of domestic industrial enterprises have developed rapidly, and the problem of determining responsibility for gas pollution emissions has become one of the main environmental protection issues in many regions. [0003] Most of the traditional atmospheric monitoring methods are fixed-point monitoring sampling, manual sampling, etc., and then the atmospheric data information obtained by sampling is transmitted to the laboratory for data analysis. Considering the sudden nature of gas pollution, it is impossible to predict where it will occur. Therefore, it is even more impossible to install monitoring devices at pollution sources in advance. Fixed-point monitori...
