Description

BACKGROUND

[0002] At present, the channel type terahertz human body security check system is widely used in public security checkpoints, subway stations, airports, railway stations, wharfs, ports, high-speed rail lines and other places with large flows of people due to its advantages of zero radiation, no stay, non-contact, good privacy protection, high security check efficiency, good imaging effect and detection of a variety of contraband.

[0003] The working principle of the channel type terahertz human body security check system is shown in FIG. 1. Figure 1 As shown in FIG. 1, when a person walks through the security check channel 20 in route A during security check, the terahertz security check instruments 31 and 32 installed in the entrance equipment room 91 and the exit equipment room 92 respectively receive the terahertz waves naturally emitted by the back and front of the person, and when the person hides a gun, a knife or other items in the clothes, there is a strong and weak contrast between the terahertz wave radiation intensity of the position where the item is located and other parts of the human body. The system represents the terahertz wave radiation intensity difference of each part of the human body in the form of a gray scale image, which is shown as a gray scale difference on the image, thereby realizing non-contact detection of the hidden items under the clothes of the person.

[0004] In actual security check applications, security personnel need to control the rate at which the detected persons enter the security check channel to ensure that there are not two or more detected persons in the security check channel at the same time, otherwise the terahertz images of adjacent detected persons will overlap, thereby affecting the judgment of suspicious dangerous goods carried by the person. Therefore, in actual applications, at least one security personnel is usually arranged at the entrance of the security check channel to artificially control the number of detected persons entering the security check channel and the distance between adjacent detected persons, which results in the need for a large number of human resources for the normal and effective operation of the security check system, and high human resource cost.

Figure 4

[0036] The control method of the system will be described in detail below, which comprises the following steps:

[0037] ​Step 100, system initialization, the main control module 10 controls the passage gate 40 to close, and initializes the entrance induction device 60 to mark as untriggered state, and initializes the exit induction device 70 to mark as triggered state.

[0038] Step 200, the verification detection device 50 verifies the identity and / or body temperature of the detected person and feeds back the detection result to the main control module 10.

[0039] Step 300, the main control module 10 detects the marking state of the exit induction device.

[0040] Step 400, the main control module 10 controls the opening or closing of the passage gate 40 according to the detection result obtained in step 200 and the marking state result of the exit induction device detected in step 300.

[0041] Step 401, if the identity verification and / or body temperature detection of the detected person in step 200 is detected as unqualified by the verification detection device, the main control module controls the passage gate 40 to close, and the detected person cannot pass through the gate.

[0042] Step 402, if the identity verification and / or body temperature detection of the detected person in step 200 is detected as qualified by the verification detection device 50, and the marking state of the exit induction device is triggered in step 300, the main control module 10 controls the passage gate 40 to open.

[0043] Step 403, if the identity verification and / or body temperature detection of the detected person in step 200 is detected as qualified by the verification detection device 50, and the marking state of the exit induction device 70 is untriggered in step 300, the main control module controls the passage gate 40 to close, and the detected person cannot pass through the passage gate 40; the main control module continues to execute step 300 until the main control module 10 detects that the marking state of the exit induction device 70 is triggered, and then the main control module 10 controls the passage gate 40 to open.

[0044] Step 500, if the main control module 10 controls the passage type gate 40 to close, the detected person cannot pass through the gate to enter the security channel 20; if the main control module controls the passage type gate 40 to open, the detected person enters the security channel 20 after passing through the passage type gate 40 and triggers the entrance sensing device 60, the entrance sensing device 60 feeds back the triggered signal to the main control module 10, the main control module 10 controls the passage type gate 40 to close at the same time, and sets the mark state of the entrance sensing device 60 and the exit sensing device 70 to the untriggered state; the two terahertz security inspection instruments 31 and 32 complete the human body detection of the detected person in the process of advancing along the security channel 20, the detected person completes the security inspection after leaving the security exit 22 and triggering the exit sensing device 70, and the security inspection of the single detected person is completed; the exit sensing device 70 feeds back the triggered signal to the main control module, and the main control module 10 marks the exit sensing device 70 as the triggered state.
