Problems solved by technology

[0004] In the gas detection, positioning and tracking system based on the electronic nose, there are few studies on the layout optimization of the electronic nose, and there is no clear layout method. As a result, the detection time of the gas by the electronic nose is inconsistent, so the layout of the electronic nose is an important part of realizing real-time and rapid gas detection

Embodiment Construction

[0018] figure 2 It is a simulation diagram of the layout of the electronic nose in a large space area. In the figure, the position of the gas source is set as the coordinate origin T(0,0), and an electronic nose P with a fixed length from the gas source is taken. 0 (x 0 ,y 0 ). The remaining electronic noses must be distributed in the area, that is, if the coordinates of the electronic noses in the area are P i (x i ,y i )(i=1,2,...,n-1), then x must be satisfied min ≤x i ≤x max ,y min ≤y i ≤y max actual constraints.

[0019] image 3 For fixing the electronic nose P in a large space area 0 and an electronic nose P i (i=1,2,...,n-1) detects the response graph of the gas source, thus it can be concluded that when the time t is reached 0 , t i (i=1,2,…,n-1), the electronic nose P 0 and P i The presence of the gas source is detected. t i The smaller it is, the faster the gas source is detected. From this consideration, whether all electronic noses can reach...

Abstract

The invention discloses a layout method for electronic noses in a large space region. The layout method comprises the following steps: confirming a layout region and a region original point according to a specific topographic condition; confirming the quantity of the electronic noses and the response time of the electronic noses to a gas source; and taking the shortest response time of the electronic noses to the gas source as an optimizing index for layout and utilizing a particle swarm optimization to solve the optimized positions of the electronic noses. According to the layout method, the gas leakage point can be detected and positioned in real time, the gas can be quickly tracked, the workers can timely and accurately have corresponding treatment and the accidents can be prevented from happening.

Description

technical field [0001] The invention belongs to the field of gas source detection, and relates to a layout optimization algorithm of an electronic nose in a large space area, and takes the shortest response time of the electronic nose to the gas source as the optimization target, so that the electronic nose can quickly detect the gas source. Background technique [0002] The rapid development of modern industry has increased the types and quantities of harmful gases that people may be exposed to in their work and life. Once a harmful gas leakage accident occurs and cannot be quickly detected, located and treated, it will not only cause great harm to the surrounding environment and equipment, but also pose a serious threat to human safety and health. Therefore, in order to ensure the safety of people's lives and property, the detection and tracking of gas leakage has important research significance. [0003] In recent years, with the rapid development of new sensors and arti...
