Embodiment Construction

[0038]Further detailed description of the technical solutions of the present invention will be described below with reference to the drawings:

[0039]The present invention proposes a method based on LS-SVM-controlled anti-drone tracestable gas pollution sources. UAV includes ultrasonic modules, high-definition zoom cameras, thermal infrared imaging modules, gas detection modules, such asfigure 1 Indicated. Among them, the drone relies on the ultrasonic module to avoid air obstacles during flight; HD zoom cameras are used to deal with interrupt pollution during the day, take photos of the pollution source, collect their geographic information and evolvement; The imaging module is used in the case of sudden pollution in the night, and the drone can still be given a geographic information collection and photo approach; the gas detection module contains all kinds of gas sensors for measuring the contaminated area flammable and explosive harmful gas concentrations.

[0040]After the drone fli...

Abstract

The invention discloses a method for tracing a sudden gas pollution source by a wind-resistant unmanned aerial vehicle based on LS-SVM control. The present invention aims to overcome the deficiencies in the prior art, and proposes a method for tracing pollution sources by mobile flight with inclined funnel trajectory, using LS-SVM to track and control the inclined funnel trajectory of the UAV, and taking wind interference factors into consideration. When the present invention traces unknown pollution sources, due to the direct special relationship between gas pollution and wind interference, the UAV stays for ten minutes after successfully tracing the pollution source to take pictures and samples, then initializes the flight data, and then circulates again to trace the pollution source , Improve the accuracy and anti-interference ability of pollution source positioning. The invention can timely and effectively trace the pollution source, and timely sample and take photos of the pollution source to obtain evidence, which is convenient for environmental supervision and management personnel to carry out follow-up remedial work, prevents the expansion of the pollution source, and also provides strong evidence for subsequent pollution determination.

Description

Technical field[0001]The present invention belongs to the field of automatic control trajectory tracking technology, and in particular, a method of investigating the pollution source in the case of wind distraction occurs.Background technique[0002]After the reform and opening up, the domestic large number of industrial enterprises rapidly developed, and the problem of gas pollution emissions, which has become one of the major concerns of many regions.[0003]The traditional atmospheric monitoring method is mostly fixed-point monitoring, artificial sampling, etc., and then transmits the sampled atmospheric data information to the laboratory for data analysis. Considering the suddenness of the gas pollution, it is not possible to predict the location of the occurrence, so it is more impossible to install the monitoring device in advance, and the fixed-point monitoring and sampling obviously cannot acquire the gas pollution source in time, specifically, accurate data. Similarly, the manu...
