Device and method for detecting gas by utilizing honeybees

Abstract

The invention discloses a device and a method for detecting gas by utilizing honeybees. The device comprises a darkroom which is internally provided with a plurality of honeybee fixing seats, feeding guide pipes for conveying gas to be detected into the darkroom, and an image collection unit for monitoring a honeybee state, wherein a plurality of the feeding guide pipes are arranged and correspond to the honeybee fixing seats one by one; and the image collection unit comprises detection light sources which correspond to the honeybee fixing seats one by one, and image collectors arranged above the honeybee fixing seats. The method comprises the following steps of: carrying out Pavlov conditioned reflex training on the honeybees; fixing the trained honeybees in the honeybee fixing seats and conveying the gas to be conveyed in front of tentacles of the honeybees; and collecting and detecting honeybee mouth images of a light-emitting opening of the detection light source by the image collectors, and judging the gas to be detected according to the collected images. Compared with the prior art, the device disclosed by the invention is high in detection precision and accuracy, and two or more than two types of gas components in the gas to be detected can be detected.

Description

technical field [0001] The invention relates to the technical field of gas detection, in particular to a device and method for detecting gas by using bees. Background technique [0002] In most cases, gases are detected in the laboratory using chemical methods or biochemical sensors. In special cases, the rapid detection of certain specific gases (such as gases emitted from drugs or explosives) is carried out by using strictly trained animals, such as the use of drug detection dogs in drug inspections; however, the training of these animals is expensive and difficult to obtain. use. [0003] Bees are animals with a strong sense of smell, and their antennae are covered with various receptors, which are extremely sensitive to specific gases. Moreover, honeybees have strong learning and memory abilities, and the Pavlovian reflex for training gases can be constructed by using the correlation learning of bees for specific gases. Use Pavlov's conditioned reflex principle to tra...

AI Technical Summary

Problems solved by technology

[0005] (1) The inside of the device is a full-light environment, and it is not conducive for bees to keep calm in a full-light environment. In an environment that does not contain training gas, beak and tongue behavior may also occur, which not only interferes with the test results, but also It is also not conducive to the survival of bees;

[0006] (2) The camera captures the image of the entire gas detection chamber or the head of the bee, and then uses image processing technology to extract the beak and tongue action of the bee in the image. Compared with the surrounding environment, the bee's beak and tongue The volume and area of ​​the part are very small, the identification is difficult, and errors such as missed detection are prone to occur. Not only is the operation complicated, but the demand for computer and hardware resources is also high;

[0007] (3) Moreover, since the antennae of the bees are constantly moving during the detection process, the monitoring of the tongue-throwing behavior will be interfered when the image is extracted, and the above-mentioned patent documents do not propose an effective solution to this;

[0008] (4) When the substance to be detected contains two or more marker gases at the same time, the above patent literature does not propose a solution for simultaneously detecting multiple marker gases to determine the substance to be detected
