Description

Technical Field

[0001] This application relates to the technical field of human body security inspection, and in particular to a human body security inspection device. Background Technology

[0002] With the continuous upgrading of global public safety needs, airports, subways, large venues and other densely populated places have put forward an urgent need for efficient and accurate body screening technology. Body screening technology plays a vital role in ensuring public safety and maintaining social order. Efficient and accurate security screening technology can detect potentially dangerous items in a timely manner and prevent them from entering public areas, thereby avoiding possible safety accidents and providing a safe and reliable environment for people's travel and activities. Against this background, research and innovation in body screening technology are also constantly advancing to meet the growing public safety needs.

[0003] To address the issue of body security checks, a combination of manual inspection and metal detectors is currently commonly used. Security personnel rely on their experience to check individuals through touch and observation, while metal detectors utilize the principle of electromagnetic induction. When a conductive object approaches, it generates a signal change, which is then used for identification.

[0004] Current security screening methods require operators to use handheld metal detectors, which is costly. Manual screening relies on operator experience, resulting in a high rate of missed detections and low efficiency. It can also cause severe congestion during peak hours. Furthermore, metal detectors can only identify conductive items and have blind spots for detecting new non-metallic dangerous items such as ceramic knives and 3D-printed guns, leading to low detection accuracy. Summary of the Invention

[0005] In order to improve the accuracy and comprehensiveness of security checks, reduce the reliance on human experience, and decrease the possibility of missed checks, this application provides a human body security inspection device.

[0009] By adopting the above technical solution and setting up an adjustable detection frame, the security inspection device can be adapted to examinees of different heights and body types, reducing scanning blind spots and improving the comprehensiveness and accuracy of security inspections. Compared with existing technologies with fixed scanning frames, it can more effectively conduct comprehensive inspections of different examinees, further improving the efficiency and quality of security inspections.

Detailed Implementation

[0028] The present application will be further described in detail below with reference to the accompanying drawings.

[0029] This application discloses a human body security inspection device to improve the accuracy and comprehensiveness of security inspections, without relying on human experience, and to reduce the possibility of missed inspections.

[0030] Example 1 refer to Figure 1 and Figure 2 A human body security inspection device includes a security inspection frame 110 and a detection component 111 disposed on the security inspection frame 110. The detection component 111 includes an X-ray emitter 112 and a detector 113. The detector 113 is located on the opposite side of the X-ray emitter 112 and forms a penetrating detection path. Specifically, the X-ray emitter 112 is the key component for generating X-rays. It is designed based on the principle of generating X-rays by electrons striking an anode target. It includes a cathode filament and an anode target. When working, the cathode filament is heated and emits electrons. The electrons are accelerated under the action of a high-voltage electric field and strike the anode target to generate X-rays. The detector 113 is used to receive X-rays and convert them into electronic information. The X-ray emitter 112 and the detector 113 are connected to a control circuit through wires. The X-ray emitter 112 and the detector 113 are arranged opposite each other to form a penetrating detection path. During the security inspection, the examinee stands between the two. The X-rays emitted by the X-ray emitter 112 pass through the human body and are received by the detector 113.

[0031] X-rays are penetrating, and detector 113 can receive X-rays after they pass through the human body and convert them into electronic information, thereby analyzing the items carried by the person. This penetrating detection path setting makes the detection range wider and can detect a variety of items, especially non-metallic dangerous goods, improving the accuracy and comprehensiveness of security checks, without relying on human experience, and reducing the possibility of missed detections.

[0032] Furthermore, the detection component 111 also includes a detection frame 114, which is mounted on the security inspection frame 110. The security inspection frame 110 is equipped with a driving component 115 for driving the detection frame 114 to slide back and forth in the vertical direction. In this embodiment, the detection frame 114 is a frame structure with certain strength and stability, which facilitates the installation of the X-ray emitter 112 and the detector 113. The X-ray emitter 112 and the detector 113 are symmetrically fixed to the detection frame 114 by bolts to ensure the accuracy of the detection path. The driving component 115 is a screw 116 and nut 117 mechanism. The screw 116 is vertically mounted on the security inspection frame 110, and the nut 117 is connected to the detection frame 114. The drive motor drives the screw 116 to rotate, thereby causing the nut 117 to move up and down along the length of the screw 116, which in turn drives the detection frame 114 to slide back and forth in the vertical direction.

[0033] The implementation principle of Embodiment 1 of this application is as follows: By setting up a liftable detection frame 114, the security inspection device can be adapted to examinees of different heights and body types, reducing scanning blind spots, which not only improves the comprehensiveness and accuracy of security inspection, but also improves the efficiency of security inspection. The detector 113 can receive X-rays after passing through the human body and convert them into electronic information, thereby analyzing the items carried by the human body, improving the accuracy and comprehensiveness of security inspection, without relying on human experience, and reducing the possibility of missed detection.

[0034] Example 2 refer to Figures 3-6 The difference from Embodiment 1 is that in this embodiment, the detection components 111 are provided in two sets, which are arranged circumferentially around the security inspection platform 220. They can detect the examinee from different angles. Specifically, the two sets of detection components 111 are a fixed detection component and an adjustable detection component. The security inspection frame 110 includes the security inspection platform 220. The fixed detection component also includes a fixed security inspection frame 211, and the adjustable detection component also includes an adjustable security inspection frame 212. Both the fixed security inspection frame 211 and the adjustable security inspection frame 212 are disposed on the security inspection platform 220. The fixed detection component has an X-ray emitter 112 and a detector 1. The X-ray emitter 112 and detector 113 of the adjustable security inspection frame 212 are symmetrically arranged within the fixed security inspection frame 211. The two sets of detection components 111 perform detection from different angles, which can more comprehensively cover the body of the examinee. The X-rays emitted from different directions can reduce the detection blind spots caused by the posture of the human body or the position of the items, further reducing the possibility of missed detection. Compared with a single set of detection components 111, it can more accurately detect the items carried by the examinee, improve the efficiency and quality of security inspection, and improve the shortcomings of existing security inspection technology in terms of detection range.

[0035] A rotating ring 221 and a security checkpoint 222 are coaxially embedded on the security inspection platform 220. The security inspection platform 220, the rotating ring 221, and the security checkpoint 222 are arranged in a concentric ring from the outside to the inside. The security inspection platform 220 is equipped with a rotating component 231 for driving the rotating ring 221 to rotate. The rotating ring 221 rotates about the central axis of the security inspection platform 220. The security inspection platform 220 is equipped with a support component 232 for supporting the security checkpoint 222. Two sets of detection components 111 are provided. Placed on the rotating ring 221, in this embodiment, the rotating component 231 is a rotating motor, which is vertically embedded in the center of the security check station 220. A straight connecting rod 223 is provided on the rotating ring 221 along the diameter of the rotating ring 221. The output shaft of the rotating motor is connected to the midpoint of the straight connecting rod 223, thereby driving the rotating ring 221 to rotate. The support component 232 consists of two support columns, which are used to support the security check station 222 and ensure the stability of the security check station 222.

[0036] By setting up a rotatable rotating ring 221 and a detection component 111, the examinee can be detected from multiple angles in an all-round way. When the rotating ring 221 rotates, the detection component 111 can rotate around the examinee and detect from different angles, which greatly reduces blind spots and improves the accuracy of security checks. At the same time, the security check platform 222 provides a stable standing platform for the examinee, improving the comfort and safety of the security check process.

[0037] The bottom of the fixed security inspection frame 211 is fixedly mounted on the rotating ring 221. The bottom of the adjustable security inspection frame 212 is slidably mounted on the rotating ring 221 along its circumference. The tops of the adjustable security inspection frame 212 and the fixed security inspection frame 211 are connected by a rotating column 216, ensuring the stability and coordination of their connection. Specifically, the fixed security inspection frame 211 and the adjustable security inspection frame 212 are metal gantry frames with certain strength and stability. The bottom of the fixed security inspection frame 211 is fixed to the rotating ring 221 by welding. The bottom of the adjustable security inspection frame 212 is provided with a sliding insert 213. The rotating ring 221 has a sliding block for... The sliding insert 213 is slidably embedded in the arc-shaped groove 224. The depth direction of the arc-shaped groove 224 is opened along the axial direction of the rotating ring 221, and the arc length direction of the arc-shaped groove 224 is in line with the curvature of the rotating ring 221. The sliding insert 213 is slidably embedded in the arc-shaped groove 224 along the arc length direction, so that the adjustable security inspection frame 212 can rotate and slide around the circumference of the rotating ring 221. The adjustable detection component can be rotatably adjusted to flexibly adjust the position and angle between the two detection components 111 according to different security inspection needs and the situation of the inspected person, adapting to inspected persons of different body types, and further improving the targeting and accuracy of security inspection. Furthermore, the bottom of the sliding block 213 is provided with two rollers 214. The two rollers 214 are symmetrically arranged at the bottom of the sliding block 213. The rollers 214 reduce the friction between the sliding block 213 and the bottom of the arc groove 224, making the rotation and sliding of the adjustment security frame 212 smoother and improving the flexibility and efficiency of adjustment.

[0038] In addition, both the fixed security inspection frame 211 and the adjustable security inspection frame 212 are equipped with an adjustment drive component 240 and a transmission component 250 for driving the X-ray emitter 112 and the detector 113 to slide back and forth synchronously in the vertical direction. The adjustment drive component 240 and the transmission component 250 are connected, and the transmission component 250 is used to connect with the X-ray emitter 112 and the detector 113. The setting of the adjustment drive component 240 and the transmission component 250 enables the X-ray emitter 112 and the detector 113 to rise and fall synchronously, which further improves the accuracy and adaptability of the detection, ensures stable detection at different heights, and reduces the detection blind zone.

[0039] The transmission component 250 includes a first transmission wheel 251, a second transmission wheel 252, and a transmission belt 253. The adjustment drive component 240 includes an adjustment drive motor 241, a first drive screw 242, and a second drive screw 243. The first drive screw 242, the adjustment drive motor 241, and the first transmission wheel 251 are coaxially connected. The second drive screw 243 and the second transmission wheel 252 are coaxially connected. The transmission belt 253 is wound around the first transmission wheel 251 and the second transmission wheel 252. The adjustment drive motor 241 drives the X-ray emitter 112 and the detector 113 to slide synchronously in the vertical direction through the first drive screw 242 and the second drive screw 243. The transmission component 250 has a simple and stable structure design and can effectively realize the synchronous lifting and lowering of the X-ray emitter 112 and the detector 113, ensuring the stability and accuracy of the detection.

[0040] To facilitate the inspection and maintenance of components such as the adjustment drive component 240 and transmission component 250 inside the fixed security inspection frame 211 and the adjustable security inspection frame 212, an inspection door 215 can be opened and closed on one side wall of both the fixed security inspection frame 211 and the adjustable security inspection frame 212, saving maintenance time and costs and improving the service life and reliability of the equipment.

[0041] The implementation principle of Embodiment 2 of this application is as follows: By setting fixed detection components and adjustable detection components, the position and angle of the detection component 111 can be flexibly adjusted according to different security inspection needs and the situation of the inspected person, further improving the pertinence and accuracy of security inspection; at the same time, the adjustment drive component 240 and the transmission component 250 ensure the synchronous lifting and lowering of the X-ray emitter 112 and the detector 113, the maintenance door 215 facilitates the maintenance of the equipment, and the roller 214 improves the smoothness of adjustment, increasing the flexibility and applicability of the security inspection device. Compared with the existing fixed structure security inspection equipment, it can better meet the security inspection requirements in different scenarios and further improve the security inspection effect.
