Description

Technical Field

[0001] The utility model relates to the field of radiation scanning, and more specifically, to a security inspection device. Background Art

[0002] In some public places (such as airports, railway stations or customs), there are clear requirements for security inspections. Taking the customs as an example, the customs has clear regulatory requirements from multiple perspectives such as the biosafety of international inbound passengers, the safety of carry-on luggage, and nuclear radiation safety. Passengers need to go through multiple security inspection links such as health declaration, body temperature detection, health declaration verification, nuclear radiation detection, carry-on luggage inspection, and risk analysis.

[0003] In the related art, for example, a patent application with the publication number CN207689691U and the name of a luggage clearance inspection system discloses a luggage clearance inspection system, including: a carry-on luggage inspection subsystem and a checked luggage inspection subsystem; wherein, the carry-on luggage inspection subsystem is used to identify the passenger's clearance identification card, scan the passenger's carry-on luggage, generate a carry-on luggage scan image for the staff to judge the image, and associate the carry-on luggage inspection result after the staff's image judgment with the passenger's clearance identification card; the checked luggage inspection subsystem is used to identify the passenger's clearance identification card, collect the barcode information of the checked luggage and scan the passenger's checked luggage, generate a checked luggage scan image for the staff to judge the image, and associate the carry-on luggage inspection result after the staff's image judgment with the passenger's clearance identification card.

[0004] In the process of implementing the concept of the present utility model, the inventor found that currently most security inspections on the market are still independent inspection links, adopting an inspection mode mainly based on manual judgment and supplemented by technical equipment. Therefore, the equipment layout of each inspection link is relatively scattered, resulting in problems such as multiple processes, layer-by-layer inspections, low passenger passing rates, poor passenger clearance experiences, many on-site devices, many systems, many screens, many repeated entries, and a large floor area, which lead to low efficiency.

[0045] Figure 1Schematically shows an overview diagram of the security inspection device according to an embodiment of the present invention. Figure 2 Schematically shows a front view of the security inspection device according to an embodiment of the present invention. Figure 3 Schematically shows a rear side view of the security inspection device according to an embodiment of the present invention.

[0046] In some embodiments, referring to Figure 1 , Figure 2 and Figure 3 , the security inspection device 100 may include a first radiation scanning device 111, a second radiation scanning device 112, a first partition wall 113, and a first radiation detection device 114. The first radiation scanning device 111 is used to perform radiation imaging on the object carried by its conveying mechanism; the second radiation scanning device 112 is used to perform radiation imaging on the object carried by its conveying mechanism; the first partition wall 113 is located between the first radiation scanning device 111 and the second radiation scanning device 112, wherein a first channel is defined between the first partition wall 113 and the first radiation scanning device 111, and a second channel is defined between the first partition wall 113 and the second radiation scanning device 112; the first radiation detection device 114 is installed on the first partition wall 113 and is used to perform two-way radiation detection on the objects in the first channel and the second channel.

[0047] The first radiation scanning device 111 or the second radiation scanning device 112 may be one of security inspection devices such as an X-ray security inspection machine or a CT scanning security inspection machine. It is applicable to check whether there are contraband items such as drugs, explosives, and flammable items in the objects to be inspected such as parcels, suitcases, and handbags in places such as stations, airports, and docks. The X-ray security inspection machine can scan the object to be inspected by means of transmission, and the CT-type security inspection machine can generate a three-dimensional scanned image of the object to be inspected through tomographic scanning, realizing rapid and three-dimensional imaging inspection of the object to be inspected.

[0048] The first radiation detection device 114 may be a millimeter wave device or a nuclear radiation detection device. The millimeter wave device can use electromagnetic waves in the millimeter wave band for imaging and detection of the human body or objects. The nuclear radiation detection device is used to locate and identify nuclear materials using gamma rays or neutron detectors. Two-way radiation detection means being able to perform radiation detection on two channels in different directions simultaneously or asynchronously.

[0049] In some embodiments, the first radiation detection device 114 includes a first neutron detection module. The first neutron detection module is installed on the first partition wall 113 and is used for bidirectional nuclear radiation detection of the objects in the first channel and the objects in the second channel. For example, the first neutron detection module includes one or more suspended gamma cameras for bidirectional visual nuclear radiation detection of the detection areas in the first channel and the second channel. This module can generate radiation alarms and visible light images of radiation alarms. The gamma camera can generate optical signals based on the interaction between gamma rays and scintillation crystals. These optical signals are then converted into electrical signals and finally form images through circuit processing. The above-mentioned detection area can be the shooting area of the gamma camera.

[0050] For example, during customs security inspections, the security inspection device 100 of this embodiment provides the first radiation scanning device 111 and the second radiation scanning device 112 placed side by side, and uses the first partition wall 113 to separate the two security inspection channels for passengers to pass through simultaneously. If a passenger in the first channel carries luggage, the luggage also needs to be placed on the conveyor belt of the first radiation scanning device 111 for radiation scanning inspection. Correspondingly, if a passenger in the second channel carries luggage, the luggage needs to be placed on the conveyor belt of the second radiation scanning device 112 for radiation scanning inspection.

[0051] The objects carried by the conveying mechanism of the first radiation scanning device 111 or the second radiation scanning device 112 can be objects such as packages, suitcases, and handbags, while the objects inspected by the first radiation detection device 114 include the passing personnel and their carried items or organisms (not placed on the conveyor belts of the first radiation scanning device 111 or the second radiation scanning device 112). The first partition wall 113 refers to a physical obstacle for separating different areas, such as a wall extending along the conveying direction of the first radiation scanning device 111 or the second radiation scanning device 112.

[0052] According to the embodiments of the present invention, by integrating two radiation scanning devices and a partition wall, using the first partition wall 113 to separate the two channels, and sharing the first radiation detection device 114 for the first channel and the second channel, compared with the method of installing multiple unidirectional radiation detection devices, the intensive design reduces the use of the site, makes the security inspection area more compact and efficient, and greatly reduces the costs of equipment wiring, equipment entry and deployment, soft decoration, etc. in terms of the comprehensive construction cost. In addition, through the first radiation detection device 114, bidirectional radiation detection is realized, reducing the repeated inspection links and improving the security inspection speed.

[0053] In some embodiments, the security inspection device 100 further includes a first entrance gate 121, a second entrance gate 122, and a third entrance gate 123. The first entrance gate 121 is close to the entrance of the first radiation scanning device 111; the second entrance gate 122 is close to the entrance of the second radiation scanning device 112; the third entrance gate 123 is connected to the first partition wall 113 and is located between the first entrance gate 121 and the second entrance gate 122; wherein, the first entrance gate 121 and the third entrance gate 123 form the entrance access device of the first channel, and the second entrance gate 122 and the third entrance gate 123 form the entrance access device of the second channel.

[0054] Both the first entrance gate 121 and the second entrance gate 122 have gates extending towards the third entrance gate 123, and the gates on both sides of the third entrance gate 123 extend towards the first entrance gate 121 and the second entrance gate 122 respectively. The third entrance gate 123 is connected to the end of the first partition wall 113. For example, when a passenger is allowed to enter the first channel through face recognition, the first entrance gate 121 and the third entrance gate 123 drive the connecting shaft to rotate through the internal drive structure, so that the inner gates of the first entrance gate 121 and the third entrance gate 123 are opened. For the first channel or the second channel, the control of the entrance access can be achieved by opening and closing the gates.

[0055] According to the embodiments of the present invention, the third entrance gate 123 is shared at the entrances of the first channel and the second channel, and the third entrance gate 123 cooperates with the first entrance gate 121 and the second entrance gate 122 respectively to form the entrance access devices of the two channels, reducing the need for additional independent gates and saving space and cost.

[0056] In some embodiments, the security inspection device 100 further includes a first exit gate 131, a second exit gate 132, and a third exit gate 133. The first exit gate 131 is close to the exit of the first radiation scanning device 111; the second exit gate 132 is close to the exit of the second radiation scanning device 112; the third exit gate 133 is connected to the first partition wall 113 and is located between the first exit gate 131 and the second exit gate 132; wherein, the first exit gate 131 and the third exit gate 133 form the exit access device of the first channel, and the second exit gate 132 and the third exit gate 133 form the exit access device of the second channel.

[0057] Both the first exit gate 131 and the second exit gate 132 have gates extending towards the third exit gate 133. The gates on both sides of the third exit gate 133 extend towards the first exit gate 131 and the second exit gate 132 respectively. The third exit gate 133 is connected to the other end of the first partition wall 113. For example, when a passenger is allowed to leave the first passage through face recognition, the first exit gate 131 and the third exit gate 133 drive the connecting shaft to rotate through the internal drive structure, so that the inner gates of the first exit gate 131 and the third exit gate 133 are opened. For the first passage or the second passage, the control of the exit passage can be achieved by opening and closing the gates.

[0058] According to an embodiment of the present invention, the third exit gate 133 is shared at the exits of the first passage and the second passage. The third exit gate 133 cooperates with the first exit gate 131 and the second exit gate 132 respectively to form an exit passage device for the two passages, reducing the need for additional independent gates and saving space and cost.

[0059] In some embodiments, the security inspection device 100 further includes: a second partition wall 115 and a first partition wall 113 are respectively located on both sides of the first radiation scanning device 111; wherein, a third passage is defined between the second partition wall 115 and the first radiation scanning device 111.

[0060] According to an embodiment of the present invention, a dual-channel layout is adopted. The first channel and the third channel are respectively arranged on the left and right sides of the first radiation scanning device 111. Security inspections are carried out simultaneously in these two channels. The advantage of this dual-channel layout is that it reduces the demand for space and the total amount of radiation detection equipment required. The parallel operation of the two channels allows passengers to queue up and pass quickly in an orderly manner, thereby significantly enhancing the passenger passing experience.

[0061] In some embodiments, the security inspection device 100 further includes a second radiation detection device 117 installed on the second partition wall 115. The second radiation detection device 117 performs unidirectional neutron detection, that is, one-way visual nuclear radiation detection of the detection area in the third passage can be carried out through one or more gamma cameras suspended.

[0062] In some embodiments, the security inspection device 100 further includes a first guiding module 141. The first guiding module 141 is near the entrance of the first radiation scanning device 111 and is communicatively connected to the first radiation scanning device 111. The first guiding module 141 includes: a first camera (not shown in the figure) for taking an appearance image of the object to be inspected; at least one first display screen 1411; a first control module (not shown in the figure) for processing the radiation image and / or the appearance image output by the first radiation scanning device 111 to obtain a conclusion on the image inspection; and a first main frame for installing the first camera, at least one first display screen 1411, and the first control module.

[0063] Exemplarily, the first guiding module 141 is used to guide passengers to conduct document identification or wait. For example, when someone is checking documents in the passage, it prompts the passengers behind to wait. When there is no one in the passage, it guides the passengers forward for inspection.

[0064] In some embodiments, at least one first display screen 1411 mainly includes the content display of the outer screen and the inner screen, and supports video intercom on the inner screen. The first guiding module 141 can also perform non-intrusive machine inspection on the passengers' carry-on luggage items. It uses the first camera to take an appearance image of the package to perform artificial intelligence identification on the problematic packages, and at the same time supports centralized image inspection and remote local image inspection. The first control module mainly generates information such as the appearance image of the package, the machine inspection image of the package (i.e., the radiation image), and the conclusion of the machine inspection image of the package.

[0065] In some embodiments, the first camera can be installed above the detection area, for example, above at least one first display screen 1411, to facilitate obtaining the optical image of the package. In some embodiments, the first camera can also be integrally installed on the top of the outer screen to facilitate taking the optical image of the package towards the object to be detected (such as the passenger's package).

[0066] In some embodiments, the first guiding module 141 further includes a first entrance gate 121 and a fourth entrance gate 124. The fourth entrance gate 124 is installed on both sides of the first main frame opposite to the first entrance gate 121.

[0067] According to the embodiments of the present invention, various components centrally installed on the first main frame, such as the first camera, the display screen, the control module, the first entrance gate 121, and the fourth entrance gate 124, help to optimize the space utilization of the security inspection area, making the overall layout more compact and reasonable. The modular design allows the first guiding module 141 to be maintained and upgraded as an independent module without large-scale modification of the entire device, effectively reducing the maintenance cost and the difficulty of upgrading.

[0068] In some embodiments, refer to Figures 1 to 3The security inspection device 100 further includes a fifth entrance gate 125 , which is connected to the second partition wall 115 and forms an entrance passage device of the third channel together with the fourth entrance gate 124 .

[0069] In some embodiments, the first radiation scanning device 111 includes a first entrance module 1113. The first entrance module 1113 is installed at the entrance of the first radiation scanning device 111 and includes: a first entrance belt conveyor for conveying the object to be inspected to the scanning area of the first radiation scanning device 111, wherein the conveying mechanism of the first radiation scanning device 111 includes the first entrance belt conveyor; a first low-temperature detection camera 1114 for performing low-temperature detection on the object to be inspected; and a first monitoring module for monitoring the carrying surface of the first entrance belt conveyor.

[0070] For example, the first entry module 1113 facilitates luggage placement for passengers. It utilizes silent technology and features an anti-pinch and anti-scratch design, effectively reducing the risk of passengers' clothing, hair, and other items becoming entangled in the tape conveyor. The first low-temperature detection camera 1114 uses thermal imaging technology to detect infrared radiation emitted by objects, generating a temperature profile for detecting low-temperature items. The first monitoring module can include a surveillance camera that monitors the loading surface of the first entry tape conveyor to detect the placement of luggage.

[0071] According to the embodiment of the present invention, the modular design allows the first entrance module 1113 to be maintained and upgraded as an independent module, and various components are installed in a centralized manner, which helps to optimize the space utilization of the security inspection area, making the overall layout more compact and reasonable, and effectively reducing maintenance costs and upgrade difficulties.

[0072] In some embodiments, the first radiation scanning device 111 further includes a first exit module 1111, which is installed at the exit of the first radiation scanning device 111. The first exit module 1111 includes: a first exit tape conveyor, which is used to convey the radiation-scanned object from the scanning area of the first radiation scanning device 111 to the exit, wherein the conveying mechanism of the first radiation scanning device 111 includes the first exit tape conveyor; a first exit guide screen 1112, which is used to display guidance information; and a second main frame, which is used to mount the first exit tape conveyor and the first exit guide screen 1112.

[0073] For example, the first exit module 1111 facilitates luggage collection for passengers and is equipped with a UPS and power module. The first exit guide screen 1112 supports multi-touch, displaying device status and passenger data in a centralized manner. The UPS supplies power to the main equipment via the power management module. The power module also features one-touch on / off and one-touch power on / off.

[0074] In some embodiments, the first exit module 1111 further includes: a first exit turnstile 131; a fourth exit turnstile 134 is installed opposite to the first exit turnstile 131 on both sides of the second main frame.

[0075] According to the embodiments of the present invention, various components centrally installed on the second main frame, such as the first exit conveyor belt, the first exit guiding screen 1112, the first exit turnstile 131, and the fourth exit turnstile 134, contribute to optimizing the space utilization of the security inspection area, making the overall layout more compact and reasonable. The modular design allows the first exit module 1111 to be maintained and upgraded as an independent module without large-scale modifications to the entire device, effectively reducing the maintenance cost and the difficulty of upgrading.

[0076] In some embodiments, referring to Figures 1 to 3 , the security inspection device 100 further includes a fifth exit turnstile 135, which is connected to the second partition wall 115 and forms an exit passage device for the third passage together with the fourth exit turnstile 134.

[0077] In some embodiments, the security inspection device 100 further includes a third partition wall 116, which is located on both sides of the second radiation scanning device 112 respectively with the first partition wall 113; wherein, a fourth passage is defined between the third partition wall 116 and the second radiation scanning device 112.

[0078] According to the embodiments of the present invention, a two-channel layout is adopted, and a second channel and a fourth channel are respectively configured on the left and right sides of the second radiation scanning device 112. Security inspections are carried out simultaneously in these two channels. The advantage of this two-channel layout is that it reduces the space requirements and the total amount of radiation detection equipment required. The parallel operation of the two channels allows passengers to queue up and pass quickly in an orderly manner, thereby significantly enhancing the passenger passing experience.

[0079] The first radiation scanning device 111 and the second radiation scanning device 112 are arranged side by side, which can provide four channels for simultaneous security inspection work, and have a centralized equipment layout, effectively improving the security inspection efficiency and saving space.

[0080] In some embodiments, the security inspection device 100 further includes a third radiation detection device 118 installed on the third partition wall 116. The third radiation detection device 118 performs unidirectional neutron detection, that is, it can perform unidirectional visual nuclear radiation detection on the detection area in the fourth passage through one or more gamma cameras hoisted.

[0081] In some embodiments, the security inspection device 100 further includes a second guiding module 151. The second guiding module 151 is near the entrance of the second radiation scanning device 112 and is communicatively connected to the second radiation scanning device 112. The second guiding module 151 includes: a second camera (not shown in the figure) for capturing an appearance image of the object to be inspected; at least one second display screen 1511; a second control module (not shown in the figure) for processing the radiation image and / or the appearance image output by the first radiation scanning device 111 to obtain a conclusion on image judgment; and a third main frame for mounting the second camera, at least one second display screen 1511, and the second control module.

[0082] Exemplarily, the second guiding module 151 is used to guide passengers to conduct document identification or wait. For example, when someone is checking in the passage, it prompts the passengers behind to wait, and when there is no one in the passage, it guides the passengers to step forward for inspection.

[0083] In some embodiments, at least one second display screen 1511 mainly includes the content display of the outer screen and the inner screen and supports video intercom on the inner screen. The second guiding module 151 can also perform non-intrusive machine inspection on the passengers' carry-on luggage items. It uses the second camera to capture the appearance image of the package to perform artificial intelligence identification on the packages with problems, and at the same time supports centralized image judgment and remote local image judgment. The second control module mainly generates information such as the package appearance image, the package machine inspection image (i.e., the radiation image), and the conclusion of the package machine inspection image.

[0084] In some embodiments, the second camera can be installed above the detection area, for example, above at least one first display screen 1511, to facilitate obtaining the optical image of the package. In some embodiments, the second camera can also be integrally installed on the top of the outer screen to facilitate shooting the optical image of the package towards the object to be detected (such as the passenger's package).

[0085] In some embodiments, the second guiding module 151 further includes a second entrance gate 122 and a sixth entrance gate 126. The sixth entrance gate 126 and the second entrance gate 122 are oppositely installed on both sides of the third main frame.

[0086] According to the embodiments of the present invention, various components centrally installed on the third main frame, such as the second camera, the display screen, the control module, the second entrance gate 122, and the sixth entrance gate 126, help to optimize the space utilization of the security inspection area, making the overall layout more compact and reasonable. The modular design allows the second guiding module 151 to be maintained and upgraded as an independent module without large-scale modification of the entire device, effectively reducing the maintenance cost and the difficulty of upgrading.

[0087] In some embodiments, refer to Figures 1 to 3The security inspection device 100 further includes a seventh entrance gate 127 , which is connected to the third partition wall 116 and forms an entrance passage device of the fourth channel together with the sixth entrance gate 126 .

[0088] In some embodiments, the second radiation scanning device 112 includes a second entrance module 1123 installed at the entrance of the second radiation scanning device 112. The second entrance module 1123 includes: a second entrance tape conveyor for conveying the object to be inspected to the scanning area of the second radiation scanning device 112, wherein the conveying mechanism of the second radiation scanning device 112 includes the second entrance tape conveyor; a second low-temperature detection camera 1124 for performing low-temperature detection on the object to be inspected; and a second monitoring module for monitoring the carrying surface of the second entrance tape conveyor.

[0089] For example, the second entry module 1123 facilitates luggage placement for passengers. It utilizes silent technology and features an anti-pinch and anti-scratch design, effectively reducing the risk of passengers' clothing, hair, and other items becoming entangled in the tape conveyor. The second low-temperature detection camera 1124 uses thermal imaging technology to detect infrared radiation emitted by objects, generating a temperature profile for detecting low-temperature items. The second monitoring module can include a surveillance camera that monitors the loading surface of the second entry tape conveyor to detect luggage placement.

[0090] According to the embodiment of the present invention, the modular design allows the second entrance module 1123 to be maintained and upgraded as an independent module, and various components are installed in a centralized manner, which helps to optimize the space utilization of the security inspection area, making the overall layout more compact and reasonable, and effectively reducing maintenance costs and upgrade difficulties.

[0091] In some embodiments, the second radiation scanning device 112 includes a second exit module 1121, which is installed at the exit of the second radiation scanning device 112. The second exit module 1121 includes: a second exit tape conveyor, which is used to convey the radiation-scanned object from the scanning area of the second radiation scanning device 112 to the exit, wherein the conveying mechanism of the second radiation scanning device 112 includes the second exit tape conveyor; a second exit guide screen 1122, which is used to display guidance information; and a fourth main frame, which is used to mount the first exit tape conveyor and the first exit guide screen 1112.

[0092] For example, the second exit module 1121 facilitates luggage collection for passengers and is equipped with a UPS and power module. The second exit guide screen 1122 supports multi-touch, displaying device status and passenger data in a centralized manner. The UPS supplies power to the main equipment via the power management module. The power module also features one-touch power on / off and one-touch power on / off.

[0093] In some embodiments, the second exit module 1121 further includes a second exit turnstile 132 and a sixth exit turnstile 136. The sixth exit turnstile 136 is installed on both sides of the fourth main frame opposite to the second exit turnstile 132.

[0094] According to embodiments of the present invention, various components centrally installed on the fourth main frame help optimize the space utilization of the security inspection area, making the overall layout more compact and reasonable. The modular design allows the second exit module 1121 to be maintained and upgraded as an independent module without the need for large-scale modifications to the entire device, effectively reducing the maintenance cost and upgrade difficulty.

[0095] In some embodiments, referring to Figures 1 to 3 , the security inspection device 100 further includes a seventh exit turnstile 137. The seventh exit turnstile 137 is connected to the third partition wall 116 and forms an exit passage device for the fourth passage together with the sixth exit turnstile 136.

[0096] In some embodiments, for either the first passage or the second passage, an entrance passage device is provided at the entrance, wherein at least one of the following modules is installed on the entrance passage device: a face recognition temperature measurement module 162 for measuring the temperature of passing personnel; a document recognition module for recognizing the documents of passing personnel; and a health status recognition module 164 for recognizing the health declaration information of passing personnel.

[0097] Exemplarily, the first passage, the second passage, the third passage or the fourth passage all have corresponding entrance passage devices. Each passage is controlled by an embedded electronic control module to drive the opening and closing of the gate structure by controlling the operation of the motor. And the embedded electronic control module is responsible for docking sensors (photoelectric, radar) to judge the state inside the passage to achieve functions such as anti-tailgating, anti-reverse, anti-intrusion, and anti-pinch.

[0098] Each entrance access device consists of two opposite turnstiles. On either turnstile, at least one of the face recognition and temperature measurement module 162, document recognition module, and health status recognition module 164 can be installed. The face recognition and temperature measurement module 162 is used to detect the faces of passengers and perform infrared temperature measurement. The face recognition and temperature measurement module 162 can include an embedded black body for temperature calibration. This module generates three data, namely body temperature, visible light image of the face, and infrared imaging image of the face. The document recognition module 163 is used to recognize the entry and exit documents of passengers. Common documents for recognition include passports, passes, etc. This module can generate information such as document number, nationality, English name, Chinese name, gender, date of birth, etc. The health status recognition module 164 is used to recognize the health declaration information of passengers, such as health codes. Each entrance access device can also be installed with an indicator light 165 for indicating the channel status. Usually, the channel has two states: prohibited access and passable. Each entrance access device can also be installed with a bag-carrying detection module 161, which can include a camera for identifying whether a passenger is carrying luggage.

[0099] In some embodiments, the security inspection device 100 may further include a network integration box 171 and a power distribution box 172. Referring to Figure 1 , the first radiation scanning device 111 and the second radiation scanning device 112 can share the network integration box 171 and the power distribution box 172, and share information with other functional components (such as entrance turnstiles, exit turnstiles, cameras, guiding screens, etc.), effectively breaking data islands, effectively connecting the data generated in each inspection link, and making the entire inspection environment form an intelligent closed-loop supervision. In addition, the security inspection device 100 may further include an easel enclosure 173 and a laser projection lamp 174 for assisting in security inspection.

[0100] In some embodiments, the security inspection device 100 may further include an entrance device status indicator light, which can be installed in the entrance area, such as on any entrance turnstile, any guiding module, or can be installed above the entrance area. The entrance device status indicator light can provide relevant light prompts about the status of the device itself for passengers or staff to be inspected.

[0101] In some embodiments, the security inspection device 100 may further include an exit device status indicator light, which can be installed in the exit area, such as on any exit turnstile, any exit guiding screen, or can be installed above the exit area. The exit device status indicator light can provide relevant light prompts about the status of the device itself for passengers or staff who have completed the inspection.

[0102] Combined with the above text and Figures 1 to 3 , the security inspection device of the present utility model can achieve multiple working modes:

[0103] Strict control mode: Passengers declare the health declaration code in advance. The health code is identified through the health status recognition module, or the passport is identified through the document recognition module. After identification, the control system of the security inspection device interacts with the upper-level system to determine whether to allow the passenger to enter the passage. If not, an alarm prompt will be given. If allowed, the passenger enters the passage. Before entering the passage, the camera of the bag-carrying detection module 161 at the entrance conducts a front-view luggage inspection on the passenger. After the passenger enters the passage, the camera of the bag-carrying detection module 161 at the entrance conducts a rear-view luggage inspection on the passenger. If the passenger has luggage that needs to be inspected, the luggage is placed. The placed luggage will be detected by the low-temperature detection camera to determine whether there are low-temperature items in the passenger's luggage. At the same time, the low-temperature detection camera will provide a video stream for recording and bind the color video during the process of the passenger placing the luggage. Subsequently, the passenger's luggage will enter the non-intrusive radiation imaging device for inspection. Then the passenger will move forward to before the exit. The camera of the bag-carrying detection module 161 set on the exit gate will conduct a front-view luggage inspection on the passenger. If the passenger has neither placed nor carried luggage, the passenger will be released. If the passenger has carry-on luggage but has not placed it for inspection, an alarm will be given for manual handling. If the passenger has carry-on luggage placed for inspection, the passenger will be released or alarmed according to the inspection result. The operating status of the equipment and the passenger information throughout the above process will be displayed on the equipment monitoring and management terminal.

[0104] Touchless customs clearance mode: Passengers can declare their health in advance and enter the passage by relying on the health declaration code or passport recognition, or they can enter the passage directly by relying on passport recognition or face temperature measurement without making a health declaration. After identification, the control system of the security inspection device interacts with the upper-level system to determine whether to allow the passenger to enter the passage. If not, an alarm prompt will be given. If allowed, the passenger enters the passage. Before entering the passage, the camera of the bag-carrying detection module 161 at the entrance conducts a front-view luggage inspection on the passenger. After the passenger enters the passage, the camera of the bag-carrying detection module 161 at the entrance conducts a rear-view luggage inspection on the passenger. If the passenger has luggage that needs to be inspected, the luggage is placed. The placed luggage will be detected by the low-temperature detection camera module to determine whether there are low-temperature items in the passenger's luggage. At the same time, the low-temperature detection camera will provide a video stream for recording and bind the color video during the process of the passenger placing the luggage. Subsequently, the passenger's luggage will enter the non-intrusive radiation imaging device for inspection. Then the passenger will move forward to before the exit. The camera of the bag-carrying detection module 161 set on the exit gate will conduct a front-view luggage inspection on the passenger. If the passenger has neither placed nor carried luggage, the passenger will be released. If the passenger has carry-on luggage but has not placed it for inspection, an alarm will be given for manual handling. If the passenger has carry-on luggage placed for inspection, the passenger will be released first. The passenger can pick up the luggage first and go to the checked luggage pick-up area. Subsequently, face recognition and alarm will be carried out in the checked luggage pick-up area according to the inspection result of the passenger's carry-on luggage. The alarm information will release or alarm according to the inspection result of the carry-on luggage. The operating status of the equipment and the passenger information throughout the above process will be displayed on the equipment monitoring and management terminal.

[0105] Left-side aisle only operation mode: The right-side aisle indicator light indicates that passage is not allowed. The roll-up banner can be manually pulled up to block the aisle to prevent passengers from rushing through it.

[0106] Right-side aisle only operation mode: The left aisle indicator light shows that passage is not allowed. The roll-up banner can be manually pulled up to block the aisle to prevent passengers from rushing through the aisle.

[0107] Normally Open Channel - Baggage Inspection - Radiation Detection Operating Mode: This mode supports Normally Open Channel - Baggage Inspection - Radiation Detection, taking into account the high passenger flow. The gate will not be closed during passenger flow, and all alarm conditions and information are pushed to the inspection station.

[0108] Channel-only and nuclear radiation detection working modes: Supports channel-only and nuclear radiation detection working modes.

[0109] Fire emergency mode: Linked with the fire emergency management system signal (this signal can also be triggered manually), all channels can be turned normally open when a fire emergency signal is received to ensure the safety of the lives of on-site personnel.

[0110] Maintenance mode: The aisle indicator light indicates that passage is not allowed. In maintenance mode, the roll-up barrier 173 can be manually pulled up to block the aisle to prevent passengers from rushing into the aisle.

[0111] Currently, most of the aforementioned inspections are conducted independently, relying primarily on manual judgment and supplemented by technical equipment. These inefficiencies include multiple processes, multiple levels of inspection, low passenger pass rates, a poor passenger experience, multiple on-site devices, multiple systems, multiple screens, and repeated data entry. Data from each link forms silos, making it difficult to connect and accurately link passenger information. Furthermore, passengers undergo repeated inspections at different stages, which can easily lead to negative emotions and complaints.

[0112] Among them, the temperature measurement devices are mostly gun-type infrared devices, mainly recording videos, and displaying alarms at the local workstation. The alarm information is neither uploaded to the integration and system nor bound to the passenger ID information and face information. The query conditions for alarm information are single, and it can only be queried by time, and the time is still the local time of the workstation. Once there is a deviation between the local time and the Beijing time, it may lead to failure to query data. Even if the data query is successful, it is a large segment of video recording with multiple people in it, and manual further identification is required. The efficiency of each data query is very low, about 20 minutes or so. At the same time, due to the limited disk space of the workstation, data cannot be stored for a long time, and the storage space cannot be flexibly expanded. The data is written in a cyclic manner, and data that needs to be locked and retained for a long time cannot be properly processed. Considering that temperature measurement devices operate independently as multiple single devices at most sites, it will cause more resource waste and labor consumption.

[0113] The health declaration and declaration verification links are also independent.

[0114] For the nuclear radiation detection equipment on the market, the main situation is still the traditional Geiger counter or scintillation detector. These technologies require that there are no radiation imaging devices, such as X-ray machines, CT machines, etc., within a certain distance of the nuclear radiation detection equipment. Therefore, there is a large waste of equipment deployment space. At the same time, the detection results have limited ability to detect energy spectra such as neutrons and gamma rays, and cannot provide visual data information. The supervision personnel's handling of alarms is relatively cumbersome. And there are the same problems as the temperature measurement devices.

[0115] Combined with one or more of the above embodiments, taking the multi-functional entry-exit passenger inspection equipment implemented based on the security inspection device provided by the present utility model as an example, it will be further described.

The left channel module may further include a second radiation detection device 117 and a first radiation detection device 114 shared with the right channel module.
