For example, after waiting to examine the personnel and all having accomplished through 4 samplings of collision formula gate when predetermineeing the number, wait for the testing result waiting to examine the personnel temporarily in predetermineeing detection area, space limiting device 8 can restrict waiting to examine the personnel in predetermineeing detection area's within range this moment, if the detection sample that waits to examine the personnel in predetermineeing the detection area detects the explosive molecule, can lock suspicious personnel's position at once for the safety inspection process is more high-efficient.
Specifically, the space defining device 8 may include a rail, a rail seat, a road block, and the like, and the embodiment is not particularly limited to the specific form of the space defining device 8.
It should be noted that the relative position relationship among the first opening/closing type gate 6, the collision type gate 4, and the second opening/closing type gate 7 may be adaptively adjusted according to an actual working scene. For example, in one of the embodiments, the collision-type gate 4 can be arranged at a position relatively close to the first opening-closing type gate 6, so that the movable space range of the person to be inspected can be enlarged in the waiting time after passing through the collision-type gate 4, and the security inspection experience of the person to be inspected is improved.
In one embodiment, the pedestrian passageway gate system comprises an alarm device 5 connected with the detection device 3; in the explosive detection method provided in the above embodiment, after the step S3, the following steps may be further included:
s40: if the detection device 3 detects the explosive molecules within the preset detection time, controlling the alarm device 5 to send alarm information;
s41: if the detection device 3 does not detect the explosive molecules within the preset detection time, the first opening-closing type gate and the second opening-closing type gate are controlled to act so as to enable the pedestrian passageway to be smooth.
The explosive detection method in the embodiment can detect the person to be detected entering the preset detection area, and if no explosive molecules are detected in the detection samples of the person to be detected in the preset detection area, the explosive molecules are directly released; if the detection sample of the person to be detected in the preset detection area detects the explosive molecules, alarm information is sent to inform security personnel to perform secondary verification, if the explosive molecules are not detected, the secondary verification is released, the order is ensured, meanwhile, the waste of human resources is reduced, and the alarm information can be sent in time to inform the security personnel when dangerous situations are found.
According to the explosive detection method in the embodiment, the preset detection area is arranged, so that the personnel to be detected can detect in batches, and the passing efficiency of security inspection is improved.
In one embodiment, when a batch of a preset number of people to be detected enter the pedestrian passageway gate system, clothes of the people to be detected are sequentially contacted with the sampling device 1, the sampling device 1 obtains a detection sample and transmits the detection sample into the pedestrian passageway gate system, and whether the people to be detected contact or carry explosives is analyzed through a fluorescence detection technology.
The explosive detection method in the embodiment does not need the cooperation of the personnel to be detected, can realize non-inductive detection, and improves the satisfaction degree of passengers. The structural design of the pedestrian passageway gate system can optimize the detection flow, the system has short component identification time, and the passing efficiency of the personnel to be detected is accelerated. The explosive detection method in the embodiment only needs 1 execution supervisor, maintains the order, and performs secondary check when the detection sample of the to-be-detected person in the preset detection area detects the explosive molecules, so that the number of used persons is reduced compared with the traditional method, and cost and efficiency of a user can be reduced.
It should be understood that, although the steps in the flowchart of fig. 4 are shown in order as indicated by the arrows, the steps are not necessarily performed in order as indicated by the arrows. The steps are not performed in the exact order shown and described, and may be performed in other orders, unless explicitly stated otherwise. Moreover, at least a portion of the steps in fig. 4 may include multiple steps or multiple stages, which are not necessarily performed at the same time, but may be performed at different times, which are not necessarily performed in sequence, but may be performed in turn or alternately with other steps or at least a portion of the other steps or stages.
