Abstract

The invention discloses a gas sampling device and a sampling method. The gas sampling device comprises a movable main body, the driving mechanism is arranged on the main body and is used for driving the sampling component; the sampling component is provided with a sampling end face, and a sampling port is formed in the sampling end face; the image acquisition unit is used for shooting an image of a to-be-detected object and sending the image to the controller; and the controller can automatically identify the image to determine a gas collection position on the outer side of the to-be-detected object and a spatial orientation of the gas collection position, so that the driving mechanism is controlled to drive the sampling port to abut against the gas collection position on the outer side of the to-be-detected object. The sampling port of the sampling part is used for abutting against the gas collection position on the outer side of the to-be-detected object for gas sampling, a non-invasive sampling scheme is adopted, articles and the like in the detected object cannot be damaged, and the problem of cross contamination caused by damage to the articles and the like in the detected object is avoided.

Description

technical field [0001] The present invention generally relates to the technical field of gas sampling, and specifically relates to a gas sampling device and a sampling method. Background technique [0002] At present, in crowded places such as ports and customs, quarantine robots can be used to inspect the contraband that may be carried in the luggage and can volatilize odor molecules. During the inspection, the security inspector needs to insert the end of the suction sampling tube into the zipper seam of the bag to be tested to perform suction detection, which may damage the items in the luggage. At the same time, there is also cross-contamination of items in different luggage risks of. SUMMARY OF THE INVENTION [0003] The present application desires to provide a gas sampling device and a sampling method, which are used to solve the problems of gas sampling by means of puncture in the prior art, such as damage to the object to be detected and cross-contamination.
