Abstract

The invention relates to a detection method for indicating the direction of an odor source in a three-dimensional environment. According to the method, odor sensors are mounted on the peak of a regular polyhedron, so that the sensors are uniformly distributed on one spherical surface. The method for solving the direction of the source of an odor pack comprises the following steps: detecting the odor pack; monitoring concentration values output by the sensors, judging that a sensor detects the odor pack if a concentration value is higher than a set threshold, taking the sensor as the first sensor, and after a second sensor and a third sensor detect the odor pack, recording the time difference in detecting the odor pack; judging if a same pack condition is met; calculating the three-dimensional source direction of the odor pack according to the time difference in detecting the odor pack; stipulating a vector of a point on the spherical surface directing to the center of sphere as the source direction of the odor pack, calculating the source direction of the odor pack, designating a point needing calculating the direction vector corresponding to the spherical surface as a target point, and solving the coordinates of the target point. The detection method has the characteristics of high precision, no need of knowing wind information and the like.

Description

technical field

[0001] The invention relates to a gas detection device and method, especially capable of indicating the direction of an odor source in a three-dimensional environment. Background technique

[0002] With the development of industry and the advancement of technology, more and more dangerous chemicals are directly or indirectly used in production and life. Once the toxic and harmful gas leaks, the harm will be huge. Historically, there have been many large-scale poisonous and harmful gas leakage accidents at home and abroad, causing heavy casualties and property losses. Therefore, the detection of odor sources, especially the detection of toxic and harmful gas leakage sources is of great significance in accident early warning, environmental monitoring, disaster rescue and other aspects.

[0003] At present, the research on odor source detection mainly focuses on the active olfactory search of robots in a two-dimensional environment, that is, the use of single ...
