Alternatively, the image recognizing section 200 is installed above in the traveling direction of the moving sidewalk 600. I.e. installed at a position where the entire travelator 600 is detected, persons and/or objects located anywhere on the travelator 600 can be located (position determination).

Optionally, the image recognition part 200 is also used for confirming the distance between adjacent persons and/or articles.

Alternatively, in some special scenarios, when the image recognition unit 200 cannot be installed at a proper position, that is, when the position of the person and/or the article on the moving sidewalk 600 cannot be determined above the moving direction of the moving sidewalk 600, for example, application scenarios such as insufficient space height, long moving sidewalk, etc., a plurality of image recognition units 200 may be installed on a plurality of sets of gas capturing devices 100 respectively to confirm the positions of the persons and/or articles to be detected.

The plurality of alarm devices 700 are electrically connected to the image recognition portion 200, and configured to send alarm information when the positions of two persons and/or objects located before and after the moving walkway 600, which are acquired by the image recognition portion 200, are too close (smaller than a preset threshold value, etc.).

Alternatively, when the positions of the front and rear persons and/or objects acquired by the image recognition unit 200 are too close to each other, the operation of the moving walkway 600 is stopped by the control unit electrically connected to the control unit.

Optionally, the alarm information includes a sound alarm, a light alarm, a sound and light alarm, and/or the like.

The following provides a TATP device detection procedure according to an embodiment of the present invention:

the luggage is a first object to be inspected, and 50g of TATP powder is contained in the luggage. The examinee, as a second test object, attached with about 0.1mg of TATP powder. The flow rate of the gas capture device 100 is 1500L/min; the distance between the two sets of gas capturing devices 100 in the moving direction of the moving walkway 600 is 2m, and two sets of gas capturing devices 100, gas

capturing device assemblies

111, 121 located on the left side of the moving walkway 600, and gas

capturing device assemblies

112, 122 located on the right side of the moving walkway are provided. The gas

capture device assemblies

111, 121, 112, and 122 have the same gettering function of capturing gas. Two

gas collection tanks

310 and 320. The image recognition sensor 200 is installed above the side of the moving direction of the moving walkway 600 (the position of people and/or objects at any position on the moving walkway 600 can be confirmed), the gas

capture device assemblies

111, 121, 112 and 122 are respectively connected with the two

gas collection boxes

310 and 320 through the gas transmission part 500, the gas

capture device assemblies

111, 121, 112 and 122 are respectively provided with a switching valve, the switching valves are respectively of two-channel design and are used for switching and connecting to the gas collection box 310 or the gas collection box 320 designated by the control part (switching is carried out between the gas collection box 310 and the gas collection box 320), the gas collection box 310 and the gas collection box 320 are respectively provided with a gas analysis part 400 and an audible and visual alarm, the moving walkway 600 has a width of 0.8 m, a length of 8m and an operating speed of 0.5m/s, and the control part is respectively connected with the gas capture, 121. 112, and 122, the image recognition sensor 200, the alarm device, and the moving walkway 600.

The bags are placed on the moving sidewalk 600 and move forwards at a constant speed along with the operation of the moving sidewalk 600. When the automatic moving walkway runs to the position of 1.5 meters, a detected person stands on the automatic moving walkway, the position information of the detected person and the luggage is obtained through the image recognition sensor 200, whether the distance between the detected person and the luggage meets the standard (the distance is too close, the detection effect is influenced), the detected person and the luggage are found after the judgment, the distance between the detected person and the luggage is 1.5 meters (the distance is too close), the control part stops the operation of the automatic moving walkway 600 until the distance between the detected person and the luggage meets the standard, the detected person goes down from the automatic moving walkway 600 at the moment, and the luggage continues to move along with the automatic moving walkway 600.

In this application scenario, the two groups of gas capture devices 100 are equally spaced along the moving walkway 600 by a distance of 2 meters, and therefore the distance less than 2 meters is not acceptable (the moving walkway is stopped), i.e., the moving walkway is stopped when the distance between the front and rear objects and/or people is less than 2 meters. Too close a distance may affect the accuracy of the gas trap in capturing the gas.

When the bag is detected by the image recognition sensor 200 to travel to the position of the gas capture device components 111, 112 (first set of gas capture device components) (2 meters), the inspected person is again on the travelator 600 (0 meters). The control part controls the gas

capturing device assemblies

111 and 112 to capture gas around the luggage and convey the gas to the gas collecting box 310 through the gas transmission part 500, the gas collecting box 310 collects the gas and then analyzes the gas through the gas analysis part 400, the gas after analysis contains TATP, and the audible and visual alarm gives out audible and visual alarm.

The time the bag reaches the location of the gas

capture device assemblies

121 and 122 is determined by the image recognition sensor 200 (4 meters). I.e. when the person under examination reaches the location (2 meters) of the gas

capture device assemblies

111 and 112. The control part controls the gas

capturing device assemblies

121 and 122 to capture gas around the bag and convey the gas to the gas collecting box 310 through the gas transmission part 500, the gas collecting box 310 collects the gas and analyzes the gas through the gas analysis part 400, the gas contains TATP after analysis, and the audible and visual alarm gives an alarm. In some scenes, the concentration of the gas collected for the first time is low, the detection result may deviate from the actual result, and the detection accuracy can be further improved by collecting the gas for multiple times and detecting the gas for multiple times.

Meanwhile, the gas

capturing device assemblies

111 and 112 acquire the gas around the inspected person, and the control unit switches the switching valve to deliver the gas collected from the surroundings of the inspected person to the gas collecting tank 320 through the gas transmission unit 500, and performs analysis and other operations.

According to this neotype TATP security installations, through setting up it in the security installations passageway, can the automatic tracking person/article examined pass through the position of security installations passageway to carry out a lot of samplings to same person/article examined, gain sufficient volume's sampling gas, thereby obtain accurate testing result. Moreover, when the checked person/article receives the TATP check, the checked person/article does not need to stay at the security check channel to be checked, and a plurality of checked persons/articles can pass through the security check channel without staying in sequence to finish the TATP check, so that the passing efficiency of the security check channel is greatly improved.
