Problems solved by technology

However, the currently proposed methods such as Markov and particle filtering, on the one hand, have a high computational time cost, and on the other hand, require a lot of prior information
(3) The current research on mobile traceability methods is still insufficient in terms of search termination criteria and leak source confirmation methods

Embodiment 1

[0041] Such as figure 1 As shown, the specific process of gas plume discovery is as follows: start the automatic traceability mechanism at the detection starting point, and the mobile robot advances against the wind at an angle of 30°-60° to the direction of the wind, as shown in Fig. figure 2 As shown, turn back and move forward in the form of Z. If the plume cannot be found after a certain step length (varies with the size of the site), reverse deflection and continue to search in the form of "Z". The search step double in length until the plume is found;

[0042] Specific process such as figure 2 As shown, the mobile robot moves forward at an angle of 15° to 60° against the wind after starting, and moves forward in a "Z" shape, with a step length of about 0.2m, forming a tracking track 2-3 between the turning surfaces. If it exceeds 20 times, Still unable to find the plume, reverse deflection, continue to search in the form of "Z", double the search step to 0.4m, form t...

Abstract

The invention relates to an automatic tracking method for leakage gas of a mobile sensor simulating female mosquitoes. Firstly, release gas is detected and sensed, then, finding of gas plume is carried out and the gas plume is tracked, and a leakage source item is confirmed after the tracking is stopped, wherein the specific process of confirming the leakage source item is as follows: after the tracking is stopped, according to an optimization algorithm and a diffusion inversion theory, a leakage source parameter when an error between a concentration detection value in the searching process and a concentration predicted value obtained by utilizing a gaussian gas diffusion model is minimum is used as a leakage source parameter estimation value so as to confirm the leakage source. Accordingto the method in the invention, source tracing of the leakage gas can be rapidly and accurately realized, and source tracing management of the gas leakage release time is improved. The automatic tracking method can be applied to the fields of chemical safety, environmental safety, disaster rescue and the like.

Description

technical field [0001] The present invention relates to the fields of electronic information, artificial intelligence, safety detection and monitoring, etc., and in particular to a method for automatically tracking gas leakage from a mobile sensor imitating a female mosquito, which can effectively realize the mobile sensor mounted on a mobile platform in a complex and special atmospheric environment Automatic traceability for volatile medium or gas leakage. Background technique [0002] Materials such as petroleum, natural gas, and organic chemical raw materials play an important role in industrial processes, and these materials often have volatile characteristics. During the storage and transportation of these materials, the leakage of storage and transportation container pipelines will cause potential environmental hazards and social hazards. In addition, the diffusion and spread of volatile pollutants in the atmosphere will bring serious potential harm. Therefore, it is...
