[0035] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0036] One embodiment of this utility model provides a dual-channel X-ray baggage inspection device, such as... Figures 1 to 4 As shown, the dual-channel X-ray baggage inspection device includes: a security inspection device 2 and a security inspection channel device 1. The security inspection device 2 includes an X-ray emitter 21, a first X-ray detector 22, and a second X-ray detector 23.

[0037] In this embodiment, the first security checkpoint 11 is located above, and the second security checkpoint 12 is located below. The first security checkpoint 11 and the second security checkpoint 12 can each be equipped with an independent conveyor belt to ensure that luggage can pass through smoothly.

[0038] The first X-ray detector 22 is located at the position corresponding to the first security checkpoint 11, and is used to capture and convert X-rays that penetrate luggage within the first security checkpoint 11. The second X-ray detector 23 is located at the position corresponding to the second security checkpoint 12, and has the same structure and function as the first X-ray detector 22, but serves the second security checkpoint 12. The X-ray emitter 21 is rotatably mounted on a bracket or shaft between the first security checkpoint 11 and the second security checkpoint 12. Its emitting end (i.e., the X-ray beam output port) can rotate at an angle.

[0039] When it is necessary to inspect luggage in the first security checkpoint 11 (upper lane), such as Figure 3 As shown, the X-ray emitter 21 rotates, precisely adjusting and positioning its emitting end towards the first security checkpoint 11. At this point, the emitted fan-shaped X-ray beam completely covers the entire effective detection area of ​​the first X-ray detector 22 located at the end / side of the first security checkpoint 11. After the rays penetrate the luggage in the upper checkpoint, they are imaged by the first detector.

[0040] When it is necessary to inspect luggage in the second security checkpoint 12 (lower lane), such as Figure 4 As shown, the X-ray emitter 21 rotates again, precisely adjusting and positioning its emitting end toward the second security checkpoint 12. The ray beam then covers and penetrates the luggage in the lower passage, and is captured and imaged by the second X-ray detector 23 below.

[0041] The dual-channel X-ray baggage inspection device provided by this invention achieves parallel dual-flow detection by setting up a first security inspection channel 11 and a second security inspection channel 12 side by side in the vertical direction. The two channels can process and transport baggage to be inspected quickly, either simultaneously or alternately. Compared with placing two single-channel devices side by side to achieve the same throughput, the dual-channel X-ray baggage inspection device provided by this invention can significantly reduce its overall footprint and provide higher security inspection capacity in a limited space.

[0042] In some embodiments, such as Figure 3 , Figure 4 and Figure 6 As shown, the security inspection and detection equipment 2 also includes: a controller 24, a first sensor 25, and a second sensor 26.

[0043] In this embodiment, the first sensor 25 is located at the entrance or inside of the first security checkpoint 11 (e.g., in front of the X-ray beam incident area). This sensor (such as a photoelectric sensor, light curtain, laser sensor, or weight sensor) is used to detect in real time whether there is luggage in the first security checkpoint 11 and whether the luggage has reached the detection position. The second sensor 26 is located at the entrance or inside of the second security checkpoint 12, and has the same function as the first sensor 25, used to detect in real time whether there is luggage in the second security checkpoint 12 and whether the luggage is ready. The controller 24 is electrically connected (wired or wirelessly) to the first sensor 25, the second sensor 26, and the X-ray emitter 21, and is responsible for processing sensor signals, coordinating system workflow, and issuing control commands.

[0044] The first sensor 25 continuously monitors the first security checkpoint 11 (upper channel). For example... Figure 3 As shown, when luggage is placed on the conveyor belt and moves to the preset detection position (or the light path of the sensor is blocked), the first sensor 25 generates a valid signal and sends it to the controller 24, indicating "Luggage to be inspected exists in the upper channel". The second sensor 26 also independently monitors the second security check channel 12 (lower channel). When it detects luggage arriving in the lower channel, it generates a valid signal and sends it to the controller 24, indicating "Luggage to be inspected exists in the lower channel".

[0045] When the controller 24 receives a "luggage present in the upper passage" signal from the first sensor 25, the controller 24 immediately (or after a certain delay according to preset logic) drives the X-ray emitter 21 to rotate. The emitting end of the X-ray emitter 21 rotates precisely towards the first security checkpoint 11 (upper passage) by a preset angle (θ1). This preset angle θ1 can be adjusted as needed to ensure that when the emitting end stops, the fan-shaped X-ray beam emitted by it can completely and without omission cover the entire effective detection area of ​​the first X-ray detector 22 at the end of the upper passage. The X-ray emitter 21 starts up and scans the luggage in the upper passage.

[0046] When the controller 24 receives the "luggage present in the lower passage" signal from the second sensor 26, such as Figure 4 As shown, controller 24 controls the rotation of X-ray emitter 21 by a corresponding angle. The emitting end of X-ray emitter 21 rotates precisely towards the second security checkpoint 12 (lower channel) by another preset angle (θ2). Angle θ2 can be adjusted as needed to ensure that the X-ray beam completely covers the detection area of ​​the second X-ray detector 23 at the end of the lower channel. X-ray emitter 21 is activated to scan and image the luggage in the lower channel.

[0047] The controller 24 can flexibly allocate channel detection priorities based on sensor signals. For example, if there is luggage in one channel but not in another, the X-ray source immediately switches to that channel for scanning. If luggage arrives at both channels simultaneously (or nearly simultaneously), the controller 24 can determine which channel to scan first according to a set strategy (such as first-come-first-served or polling), and automatically switch to the other channel immediately after completing the scan.

[0048] In some embodiments, such as Figure 6 As shown, the security inspection equipment 2 also includes a first motor 27. The first motor 27 is electrically connected to the controller 24, and a rotating shaft is connected to the X-ray emitter 21, with the rotating shaft being drive-connected to the first motor 27. The first motor 27 (e.g., a servo motor or a stepper motor) can be fixedly mounted on the internal frame of the equipment. Its output shaft is connected to the rotating shaft on the housing of the X-ray emitter 21 via a transmission mechanism (e.g., a rigid coupling, a reduction gearbox, a belt drive, etc.). The first motor 27 is electrically connected to the controller 24 and receives rotation commands from the controller 24.

[0049] In some embodiments, such as Figure 1 , Figure 2 and Figure 5 As shown, the X-ray emitter 21 has two emitting ends. When one emitting end of the X-ray emitter 21 is rotated to face the first security checkpoint 11, the other emitting end of the X-ray emitter 21 is rotated to face the second security checkpoint 12.

[0050] For example, the first emitting end is mainly designed to irradiate the first security checkpoint 11 (upper channel). The second emitting end is mainly designed to irradiate the second security checkpoint 12 (lower channel). These two emitting ends are fixed to the housing of the X-ray emitter 21 and are arranged in a specific spatial angular relationship (usually back-to-back symmetrical arrangement, i.e., the angle between the central ray directions of the two is close to or equal to 180 degrees). The first X-ray detector 22 is located in the first security checkpoint 11 and receives the rays from the first emitting end. The second X-ray detector 23 is located in the second security checkpoint 12 and receives the rays from the second emitting end.

[0051] When there is luggage in the first security checkpoint 11 (upper channel) (first sensor 25 is triggered) and there is luggage in the second security checkpoint 12 (lower channel) (second sensor 26 is triggered), the two emitting ends of the X-ray emitter 21 are respectively directed towards the first security checkpoint 11 and the second security checkpoint 12, and the detection of the upper and lower channels can be completed using a single X-ray emitter 21.

[0052] In some embodiments, such as Figure 1 and Figure 2As shown, the first security checkpoint 11 is located at the top vertically. A first conveyor belt 111 is installed within its interior space. This conveyor belt runs along the length of the checkpoint and is used to carry and horizontally transport luggage awaiting inspection. A second conveyor belt 121 is located vertically below the first security checkpoint 11. A second conveyor belt 121, with the same structure and function as the first conveyor belt 111, is also installed within its interior space to carry and transport luggage awaiting inspection. An X-ray emitter 21 is located at the bottom of the first conveyor belt 111. A first X-ray detector 22 is installed at the top of the first security checkpoint 11 (i.e., directly above or adjacent to the top frame of the checkpoint). Its detector array (e.g., L-shaped) faces downward toward the first conveyor belt 111 and the emitter position. A second X-ray detector 23 is installed at the bottom of the second security checkpoint 12 (i.e., directly below or adjacent to the bottom frame structure of the second conveyor belt 121). Its detector array (e.g., L-shaped) faces upward toward the second conveyor belt 121.

[0053] When it is necessary to inspect the luggage in the first security checkpoint 11 (upper channel), the X-ray emitter 21 emits an upward beam that passes through the first conveyor belt 111 and covers the entire detection area of ​​the first X-ray detector 22 located at the top of the first security checkpoint 11.

[0054] When it is necessary to inspect luggage in the second security checkpoint 12 (lower channel), the X-ray emitter 21 emits a beam of light downwards, which passes through the second conveyor belt 121 and covers the entire detection area of ​​the second X-ray detector 23 located at the bottom of the second security checkpoint 12.

[0055] To make it easier for users to place their luggage, such as Figure 1 As shown, the first conveyor belt 111 extends to the entrance and exit of the first security checkpoint 11, respectively. The first conveyor belt 111 extends beyond the entrance of the first security checkpoint 11 to form a clearly visible upper-aisle baggage placement platform (entrance extension). Operators or passengers can easily and directly place their baggage to be inspected on this extension platform. The first conveyor belt 111 extends beyond the exit (rear end of the channel) of the first security checkpoint 11 to form an upper-aisle baggage receiving / picking platform (exit extension). Scanned baggage is automatically conveyed to this platform for user collection.

[0056] Similarly, the two ends of the second conveyor belt 121 extend to the entrance and exit of the second security checkpoint 12, respectively. The second conveyor belt 121 extends a distance beyond the entrance (front end) of the second security checkpoint 12 to form a lower-channel baggage placement platform (entrance extension). The second conveyor belt 121 extends a distance beyond the exit (rear end) of the second security checkpoint 12 to form a lower-channel baggage receiving / picking platform (exit extension).

[0057] To increase the scope of detection, such as Figures 1 to 5 As shown, the first X-ray detector 22 covers the entire top surface of the first security checkpoint 11, and the second X-ray detector 23 covers the entire bottom surface of the second security checkpoint 12.

[0058] In this embodiment, both the first X-ray detector 22 and the second X-ray detector 23 are made of a large, continuous detector array panel.

[0059] In the width direction of the first security checkpoint 11, the first X-ray detector 22 completely spans and covers the entire width of the first conveyor belt 111, ensuring that the X-ray penetration signal from the top of the luggage can be captured without omission, regardless of its position on the conveyor belt (center, left, or right). In the length direction of the first security checkpoint 11, the first X-ray detector 22 also covers the entire section within the checkpoint that requires imaging analysis, ensuring effective signal acquisition of luggage as it passes through different positions in the detection area (front, middle, and rear).

[0060] In the width direction of the second security checkpoint 12, the second X-ray detector 23 completely spans and covers the entire width of the second conveyor belt 121, ensuring that the X-ray penetration signal from the top of the luggage is captured without omission, regardless of its position on the conveyor belt (center, left, or right). In the length direction of the second security checkpoint 12, the second X-ray detector 23 also covers the entire section within the checkpoint that requires imaging analysis, ensuring effective signal acquisition of luggage as it passes through different positions in the detection area (front, middle, and rear).

[0061] In some embodiments, such as Figure 1 and Figure 2 As shown, the first security check channel 11 is provided with a plurality of spaced first rollers 112, and the first conveyor belt 111 is fitted on the plurality of first rollers 112; the second security check channel is provided with a plurality of spaced second rollers 122, and the second conveyor belt 121 is fitted on the plurality of second rollers 122.

[0062] In this embodiment, a plurality of first rollers 112 are fixedly installed inside the first security check channel 11 (upper channel) along the conveyor belt path direction (baggage transport direction). These first rollers 112 are arranged at intervals, and their support points are evenly distributed below the first conveyor belt 111. The first conveyor belt 111 is fitted onto the first rollers 112 with appropriate tension. The rotation of the first rollers 112 supports and guides the movement of the first conveyor belt 111.

[0063] Similarly, inside the second security checkpoint 12 (lower channel), multiple second rollers 122 are fixedly installed along the conveyor belt path (baggage transport direction). These second rollers 122 are arranged at intervals, with support points evenly distributed below the second conveyor belt 121, which is fitted onto the second rollers 122 with appropriate tension. The rotation of the first roller 112 supports and guides the movement of the second conveyor belt 121.

[0064] The dual-channel X-ray baggage inspection device also includes a drive unit. The drive unit may be an electric motor, and is driven by at least one first roller 112 and at least one second roller 122. The drive unit is driven by at least one first roller 112 via a transmission mechanism (such as a chain, belt, gear, or direct coupling). This driven first roller 112 is typically referred to as the driving roller (e.g., located at the entrance or exit end), and its rotation drives the first conveyor belt 111 via friction; the other first rollers 112 are driven rollers. Simultaneously (or independently), the drive unit is also driven by at least one second roller 122 via a transmission mechanism (similarly, this second roller 122 becomes the driving roller of the lower channel conveyor belt).

[0065] Based on the above embodiments, in some embodiments, such as Figure 1 As shown, the length of the second security checkpoint 12 is greater than the length of the first security checkpoint 11. Here, length refers to the total effective passage distance along the baggage conveying direction (X-axis), from the starting point of the entrance extension to the ending point of the exit extension.

[0066] The second security checkpoint 12, being closer to the ground and with a more stable load-bearing foundation, offers greater physical space for handling oversized, overweight, or heavy luggage due to its extended length. Such luggage might not be fully accommodated or would be difficult to maneuver in the first security checkpoint 11.

[0067] Furthermore, the length difference between the first security checkpoint 11 and the second security checkpoint 12 creates a natural misalignment. The entrance / exit platform of the second security checkpoint 12 extends further forward or backward than the upper checkpoint, avoiding spatial interference between passengers on different levels when placing / retrieving their luggage. This guides the flow of passengers with large luggage from those with carry-on luggage, improving traffic order.

[0068] Based on the above embodiments, in some embodiments, such as Figure 1 and Figure 2As shown, the first security checkpoint 11 and / or the second security checkpoint 12 are equipped with multiple parallel multi-channels. Physical partition structures, such as partitions or guide rails, can be installed along the width direction (Y-axis) of the first security checkpoint 11 and / or the second security checkpoint 12, dividing a single channel into two or more independent parallel sub-channels. After horizontally dividing a single channel into N sub-channels, one device can process multiple bags or packages simultaneously, overcoming the single-channel processing speed bottleneck. At the same time, a single X-ray emitter 21 can still complete the inspection of multiple sub-channels.

[0069] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
