Cargo inspection equipment and inspection method

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application is based on and claims priority to the Chinese patent application with application number 202311864769.3 and application date December 29, 2023. The disclosed content of the Chinese patent application is hereby introduced as a whole into this application. Technical Field

[0003] The present disclosure relates to the field of inspection, and in particular to a cargo inspection device and an inspection method thereof. Background Art

[0004] Cargo inspections, such as those conducted by customs, involve the health quarantine and inspection of goods and personnel. Some customs and quarantine-related technologies involve sniffing for odors within containers. This can involve manually inserting a gas sniffing instrument's probe through the gap in the container door to collect gas from within the container. If necessary, the container door may even need to be opened to sample the gas for analysis to determine the material properties of the cargo. Cargo inspections, such as those conducted by customs, also typically involve generating and processing visual images of cargo vehicles using X-ray cargo vehicle inspection systems.

[0005] For inspection scenarios involving X-ray imaging inspection and odor sniffing, some related technologies install one or several fixed locations of the air sampling device at the site of the X-ray imaging inspection system, and collect the odor in the container before or after the X-ray imaging inspection to assist in judging the material properties of the cargo. Summary of the Invention

[0006] After research, the inventors found that the X-ray imaging inspection and odor sniffing inspection in the related technology are two independent serial processes, which require two independent sets of equipment, are costly, take a long time to inspect, and are inefficient, thus affecting the overall efficiency of cargo transportation; moreover, the odor sniffing inspection requires human operation, which is heavy work and low efficiency, and poses certain safety hazards to personnel health. In addition, sampling needs to be performed at a specific location of the inspected object when the inspected object is in a stopped state, which affects the overall customs clearance efficiency in cargo inspection scenarios such as customs.

Compared to the related art, which performs scanning imaging inspection and odor detection inspection separately in a serial manner, the embodiments of the present disclosure can save inspection time, improve inspection efficiency, and contribute to improving the overall efficiency of cargo transportation. Furthermore, since both the radiographic scanning component and the gas sampling component are arranged on the carrier, the number of components can be reduced, which helps to reduce costs.

[0074] All terms (including technical or scientific terms) used in this disclosure have the same meaning as those understood by one of ordinary skill in the art to which this disclosure belongs, unless otherwise specifically defined. It should also be understood that terms defined in, for example, general dictionaries should be interpreted as having a meaning consistent with their meaning in the context of the relevant technology, and should not be interpreted in an idealized or highly formal sense, unless explicitly defined herein.

[0075] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0076] For inspection scenarios involving X-ray imaging inspection and odor sniffing, some related technologies install one or several fixed locations of the air sampling device at the site of the X-ray imaging inspection system, and collect the odor in the container before or after the X-ray imaging inspection to assist in judging the material properties of the cargo.

[0077] In the related technology, X-ray imaging inspection and odor sniffing inspection are two independent serial processes, which require two independent sets of equipment, are costly, take a long time to inspect, and are inefficient, thus affecting the overall efficiency of cargo transportation; moreover, odor sniffing inspection requires human operation, which is laborious, inefficient, and poses certain safety hazards to personnel health.

[0078] In view of this, the embodiments of the present disclosure provide a cargo inspection device and an inspection method thereof, which can take into account the needs of radiographic inspection and odor sniffing inspection, thereby improving inspection efficiency.

[0079] FIG1 is a schematic diagram of the structure of some embodiments of the cargo inspection device according to the present disclosure. FIG2 is a schematic diagram of the structure of other embodiments of the cargo inspection device according to the present disclosure. Referring to FIG1 and FIG2, an embodiment of the present disclosure provides a cargo inspection device, comprising: a carrier 10, a scanning imaging inspection device 20, and an odor inspection device 30. The carrier 10 is configured to move relative to the inspected cargo G along a preset direction during the cargo inspection process. The scanning imaging inspection device 20 has a ray scanning component 21 for scanning the inspected cargo G by rays. The odor inspection device 30 has a gas sampling component 31 for sampling gas from the inspected cargo G. Both the ray scanning component 21 and the gas sampling component 31 are arranged on the carrier 10, and the ray scanning process implemented by the ray scanning component 21 and the gas sampling process of the gas sampling component 31 at least partially overlap in time.

[0080] This embodiment arranges a radiation scanning component of a scanning imaging inspection device and a gas sampling component of an odor inspection device on a carrier that moves relative to the inspected goods, and makes the radiation scanning process implemented by the radiation scanning component and the gas sampling process of the gas sampling component at least partially overlap in time, thereby achieving a certain degree of integration of the scanning imaging inspection process and the odor sniffing inspection process.

[0081] Compared to related art methods that perform scanning and odor detection inspections in a serial manner, the disclosed embodiments can save inspection time and improve inspection efficiency, thereby enhancing the overall efficiency of cargo transportation. Furthermore, both the X-ray scanning component and the gas sampling component are located on a carrier, reducing the number of components and thus lowering costs. Furthermore, the odor detection device can reduce the level of human involvement, minimizing the adverse health effects of the odor detection process and reducing the labor intensity of participants required by performing both the scanning and odor detection processes separately.

[0082] During the cargo inspection process, the carrier 10 and the inspected cargo G move relative to each other. In some embodiments, the relative movement of the carrier 10 and the inspected cargo G means that the carrier 10 remains stationary, and the inspected cargo G moves by its own power or is driven by other mechanisms. In other embodiments, the relative movement of the carrier 10 and the inspected cargo G means that the inspected cargo G remains stationary, and the carrier 10 moves by its own power or is driven by other mechanisms. In addition, the relative movement of the carrier 10 and the inspected cargo G may also mean that both the carrier 10 and the inspected cargo G move, and the movement speeds and / or movement directions are different.

[0083] In order to achieve the movement of the carrier 10 during transfer, transportation or cargo inspection, in some embodiments, the carrier 10 includes a movable body so as to travel on a site or road; in other embodiments, the carrier 10 may have a walking device, such as a roller assembly capable of running on a track or site surface.

[0084] The inspected cargo G can take various forms, such as parcels, cargo boxes, containers, or vehicles. Vehicles can include various types of motor vehicles (e.g., cars, buses, vans, container trucks, etc.) or trains (e.g., passenger trains or freight trains, etc.). Taking a container truck as an example, the inspected cargo G can be the container carried by the container truck, or the container truck containing the container.

[0085] The scanning imaging inspection device 20 includes a radiation scanning assembly 21 for scanning the inspected cargo G using radiation. The radiation can be either X-rays or gamma rays. In some embodiments, the radiation scanning assembly 21 may include a radiation source and a detector. The radiation source is configured to output radiation of a predetermined energy. The detector is configured to detect radiation emitted by the radiation source after it impacts the inspected cargo G and generate a detection signal.

[0086] For example, when a radiation source emits X-rays, they pass through the inspected cargo G from one side and, after attenuation, are detected by a detector located on the other side of the inspected cargo G, thereby forming a transmission detection signal. Another example is when a radiation source emits X-rays, the backscattered signals generated by the X-rays in the inspected cargo G are detected by a detector on the same side as the radiation source, thereby forming a backscattered detection signal.

[0087] Taking a container truck as an example, the carrier 10 equipped with the ray scanning component 21 can be moved along the length direction of the container truck via a track on the site so that the ray scanning component 21 can perform ray scanning on the container truck from the front to the rear or from the rear to the front.

[0088] With reference to Figures 1 and 2 , in some embodiments, the scanning imaging inspection device 20 further includes an imaging component 22 connected to the radiation scanning component 21. The imaging component 22 can be connected to the radiation scanning component 21 via a wired or wireless connection to obtain detection signals generated by the radiation scanning component 21 through radiation scanning, and obtain a scanned image of the inspected cargo G based on the detection signals. In this way, the attributes of the items within the inspected cargo can be determined by analyzing the shape, outline, and color reflected in the scanned image.

[0089] As shown in Figure 1 , the imaging assembly 22 can be disposed outside the carrier 10, independently of the carrier 10. For example, the imaging device 22 can be a host computer or remote server that wirelessly communicates with the X-ray scanning assembly 21 and has imaging capabilities. This helps simplify the structure supported by the carrier 10, reduces weight, and reduces the energy consumption required to drive the carrier 10. It also enables remote control and monitoring of the X-ray scanning inspection process.

[0090] In other embodiments, the imaging assembly 22 may also be disposed on the carrier 10 as shown in FIG2 . Accordingly, the imaging assembly 22 is also moved, transferred, and transported together with the carrier 10 to achieve greater integration, thereby reducing the size of the device and improving its flexibility.

[0091] The odor detection device 30 includes a gas sampling assembly 31. The gas sampling assembly 31 is used to sample the gas from the inspected cargo G. The gas here can be volatile gases emitted from the surface or interior of the inspected cargo G, such as those emitted by cargo inside a container. By sampling the gas from the inspected cargo G, the gas sample can be further processed and analyzed by the odor analysis assembly 32, thereby enabling the detection of hazardous chemicals, explosives, and the like.

[0092] With reference to Figures 1 and 2, in some embodiments, the odor detection device 30 further includes an odor analysis component 32. The odor analysis component 32 can process and analyze the gas samples collected by the gas sampling component 31. For example, the odor analysis component 32 can use an odor sniffing device to perform concentration and other processing on the collected gas, and then analyze it to obtain analysis results. The odor analysis component 32 can be based on, but not limited to, mass spectrometry, ion mobility, gas chromatography-ion mobility spectrometry, and their combined technologies, and can perform qualitative and quantitative analysis and detection of toxic and harmful gases, volatile hazardous chemicals, odors of animal and plant products and foods, volatile drugs, precursor chemicals, and explosives.

[0093] The gas sample collected by the gas sampling component 31 can be transported from the gas sampling component 31 to the odor analysis component 32 through a transport pipeline, or can be moved to the odor analysis component 32 manually or by other equipment after collection.

[0094] As shown in Figure 1, the odor analysis component 32 can be installed outside the carrier 10, independently of the carrier 10. For example, the odor analysis component 32 can be located in a monitoring room or laboratory outside the site and receive gas samples transferred manually or by other equipment. This helps simplify the structure of the carrier 10, reducing weight and energy consumption required to drive the carrier 10. It also allows for a richer range of odor analysis functions without being restricted by the structural requirements of the carrier 10.

[0095] In other embodiments, the odor analysis component 32 can also be mounted on the carrier 10, as shown in Figure 2. Accordingly, the odor analysis component 32 can be moved, transferred, and transported along with the carrier 10, achieving greater integration, reducing device size, and increasing operational flexibility. The odor analysis component 32 can be connected directly or via a pipeline to the gas sampling component 31 to obtain gas samples collected by the gas sampling component 31.

[0096] In this embodiment, the radiation scanning process implemented by the radiation scanning assembly 21 and the gas sampling process of the gas sampling assembly 31 at least partially overlap in time. The radiation scanning process can completely overlap with the gas sampling process, or they can partially overlap. The overlapping time period of the radiation scanning process and the gas sampling process can effectively save inspection time and improve overall inspection efficiency compared to non-overlapping radiation scanning and gas sampling processes.

[0097] For example, as the carrier 10 and the inspected goods G move relative to each other, the radiation scanning component 21 is first started to perform radiation scanning, and the gas sampling component 31 is started to perform gas sampling during the radiation scanning process, and the gas sampling process is stopped before, at the same time as, or after the end of the radiation scanning process.

[0098] For another example, as the carrier 10 and the inspected goods G move relative to each other, the gas sampling component 31 is first started to perform gas sampling, and during the gas sampling process, the radiation scanning component 21 is started to perform radiation scanning, and the radiation scanning process is stopped before, at the same time as, or after the end of the gas sampling process.

[0099] As the carrier 10 and the inspected goods G move relative to each other, the radiation scanning of the radiation scanning component 21 and the gas sampling of the gas sampling component 31 can be started simultaneously, and the radiation scanning process can be stopped before, simultaneously with, or after the gas sampling process ends.

[0100] To more effectively control the temporal overlap of at least a portion of the radiation scanning process performed by the radiation scanning assembly 21 and the gas sampling process performed by the gas sampling assembly 31, referring to FIG2 , in some embodiments, the cargo inspection apparatus may further include a controller 60. The controller 60 may be signal-connected to at least one of the carrier 10, the scanning imaging inspection device 20, and the odor detection device 30. The controller 60 may coordinate the radiation scanning process and the gas sampling process during the cargo inspection process by issuing instructions to at least one of the carrier 10, the scanning imaging inspection device 20, and the odor detection device 30.

[0101] In some embodiments, the controller 60 may also issue instructions to the imaging component 22 and the odor analysis component 32, causing the imaging component 22 to output a scanned image of the inspected cargo G obtained based on the detection signals from the X-ray scanning component 21 during the cargo inspection process, and causing the odor analysis component 32 to output analysis results of the gas samples collected by the gas sampling component 31 during the cargo inspection process. The controller 60 may also issue instructions to the carrier 10 to cause the carrier 10 to move or stop relative to the inspected cargo G.

[0102] The controller 60 and its signal connection relationship with the carrier 10, the scanning imaging inspection device 20 and the odor inspection device 30 in FIG2 are also applicable to the embodiment shown in FIG1.

[0103] The controller 60 can be implemented using one or more application-specific integrated circuits (ASICs), digital signal processors (DSPs), programmable logic devices (PLDs), field programmable gate arrays (FPGAs), processors, microcontrollers, microprocessors, or other electronic components. The controller 60 can be provided on the carrier 10 or independently provided on a remote control platform server.

[0104] 2 , in some embodiments, the cargo inspection apparatus further includes a synchronization mechanism 40. The synchronization mechanism 40 is connected to the gas sampling assembly 31 and is configured to maintain the gas sampling assembly 31 relatively stationary relative to the inspected cargo G or maintain its displacement relative to the inspected cargo G within a preset displacement difference range while the radiation scanning assembly 21 moves relative to the inspected cargo G with the carrier 10 and scans the inspected cargo G, and to perform gas sampling on the inspected cargo G.

[0105] The synchronization mechanism 40 synchronizes the gas sampling assembly 31, ensuring that the gas sampling assembly 31 remains relatively stationary (i.e., its relative displacement is zero) or within a preset displacement difference range relative to the inspected cargo G during the gas sampling process. This allows the gas sampling assembly 31 to stably and continuously sample gas from the inspected cargo G. Maintaining relative stationary conditions further improves the stability and continuity of gas sampling, while maintaining the displacement of the gas sampling assembly 31 relative to the inspected cargo G within the preset displacement difference range reduces the high synchronization accuracy requirements of the synchronization mechanism 40.

[0106] The preset displacement difference range can be determined based on factors such as the size of the gas sampling assembly 31 and the size of the sampling area of ​​the inspected cargo G. For inspected cargo G with smaller vents, the larger gas sampling assembly 31 can be allowed to slightly move relative to the vents during the gas sampling process, while still ensuring continuous and stable gas sampling. The preset displacement difference range can include the displacement difference range in the direction of relative motion between the carrier 10 and the inspected cargo G, as well as the displacement difference range in a direction perpendicular to that direction.

[0107] Referring to FIG2 , the controller 60 can be signal-connected to the synchronization mechanism 40 and coordinate the synchronization of the gas sampling assembly 31 by issuing instructions to the synchronization mechanism 40. The synchronization mechanism 40 can employ, but is not limited to, a linear motor, a rack and pinion, a lead screw guide, an articulated robot, or the like to achieve movement in at least one direction (e.g., movement in the orthogonal x, y, and z axes) to achieve synchronous operation, thereby achieving precise positioning of the gas sampling assembly 31 relative to the gas sampling area of ​​the inspected cargo G under the control of the controller.

[0108] Figures 3 and 4 are schematic diagrams of application scenarios according to some embodiments of the cargo inspection device of the present disclosure, viewed from above and below, respectively. Referring to Figure 3 , in some embodiments, the synchronization mechanism 40 includes a mounting member 41 for mounting the gas sampling assembly 31 . The synchronization mechanism 40 is configured to cause the mounting member 41 to move in a direction opposite to the preset direction at a preset rate, or at a rate that differs from the preset rate within a preset rate difference range, when the carrier 10 moves in a preset direction at a preset rate relative to the inspected cargo G.

[0109] For example, in Figure 3 , the container truck, representing the inspected cargo G, remains stationary, while the carrier 10 moves in a direction opposite to direction x (parallel to the length of the container truck) at a rate a, enabling continuous radiographic scanning by the radiographic scanning assembly 21 from the front to the rear of the truck. During this process, the gas sampling assembly 31 mounted on the mounting member 41 is docked with the container truck's vent. Under the synchronizing action of the synchronization mechanism 40, the mounting member 41 moves relative to the carrier 10 in direction x at a rate b. This rate b is equal to the rate a, thereby keeping the mounting member 41 and the gas sampling assembly 31 stationary relative to the container truck, ensuring continuous docking of the gas sampling assembly 31 with the container truck's vent, thereby ensuring continuous and stable gas collection.

[0110] The rate b may not be equal to the rate a, and the difference between the two is within a preset rate difference range, so that the displacement of the gas sampling component 31 relative to the inspected cargo G during the gas sampling process remains within the preset displacement difference range.

[0111] Referring to Figures 3 and 4 , in some embodiments, the carrier 10 includes a cabin 11 and an arm 12. The cabin 11 supports the scanning imaging inspection device 20 and some components of the odor detection device 30, and connects to and supports the arm 12. The arm 12 and the cabin 11 define an inspection passage for the inspected cargo G to pass through.

[0112] In Figure 4 , the arm 12 includes a support arm 121, a horizontal detection arm 122 connected to the support arm 121, and a vertical detection arm 123 connected to the horizontal detection arm 122. The support arm 121 is fixedly or rotatably mounted on the cabin 11. Accordingly, an inspection passage can be enclosed by a portal frame formed by the outer wall of the cabin 11 and the arm 12. Both the cabin 11 and the arm 12 can be coupled to a track provided on the site via rollers to enable movement of the cabin 11 and the arm 12 along the extension direction of the track.

[0113] The synchronization mechanism 40 may be disposed on the cabin 11 and / or the arm 12. In Figure 4 , the synchronization mechanism 40 is disposed on the cabin 11 and is located on the top surface of the cabin 11. In other embodiments, the synchronization mechanism 40 may also be disposed on the arm 12, for example, on the horizontal detection arm 122 or the vertical detection arm 123, to collect gas from the top vent of the inspected cargo G or the vent on the side away from the cabin 11.

[0114] 5 , in some embodiments, the synchronization mechanism 40 includes a support 42 and a mounting member 41. The support 42 is disposed on the cabin 11 and / or the arm 12. The mounting member 41 is movably disposed on the support 42. The gas sampling assembly 31 is mounted on the mounting member 41.

[0115] The support 42 can be fixed to the cabin 11 and / or the arm 12 by means of connectors or welding, or can be integrally formed with the cabin 11 or the arm 12. The mounting member 41 can adopt various structural forms, such as the one shown in FIG4 , which includes a seat 411 that can slide integrally on the top wall of the cabin 11. The seat 411 is provided with a fixed or movable outrigger 412, and the end of the outrigger 412 can be mounted with the gas sampling assembly 41. In FIG4 , the mounting member 41 can form a sliding fit with a slide rail located on the top wall of the cabin 11. That is, the mounting member 41 and the support 42 can slide in a preset direction. Here, the extension direction of the slide rail can be parallel to the direction of movement of the carrier relative to the inspected cargo G. In this way, the mounting member 41 can move integrally along the support 42, so that the gas sampling assembly 31 can remain relatively stationary with the inspected cargo G more stably during the gas sampling process, or its displacement relative to the inspected cargo G can be kept within a preset displacement difference range.

[0116] In other embodiments, the mounting member 41 may comprise a multi-jointed robotic arm, with some segments of the robotic arm capable of moving relative to the support 42, to ensure that the gas sampling assembly 31 remains relatively stationary relative to the inspected cargo G or maintains its displacement relative to the inspected cargo G within a preset displacement difference range during the gas sampling process. A mounting member 41 in the form of a multi-jointed robotic arm can provide greater flexibility and adaptability to various scenarios.

[0117] 2 and 3 , in some embodiments, the cargo inspection device further includes a sampling area identification element 50. The sampling area identification element 50 may be disposed outside the carrier 10, such as on a site, or may be disposed on the carrier 10. The sampling area identification element 50 is configured to identify a gas sampling area of ​​the inspected cargo G, so that the carrier 10 and / or the synchronization mechanism 40 can adjust the gas sampling assembly 31 to a sampling position corresponding to the gas sampling area.

[0118] By identifying the gas sampling area of ​​the inspected cargo G through the sampling area identification element 50, the gas sampling component 31 can be easily adjusted to the sampling position corresponding to the gas sampling area, saving the workload of manually adjusting the carrier position or the gas sampling component position and improving inspection efficiency.

[0119] The gas sampling area of ​​the inspected cargo G may be outside the inspected cargo G, for example, a location of the inspected cargo G adjacent to or away from the carrier 10, or below or above the inspected cargo G. The gas sampling area of ​​the inspected cargo G may also be inside the inspected cargo G or a location connected to the interior of the inspected cargo G.

[0120] For some inspected goods G, the gas sampling area has a certain degree of visual recognition, and the specific location of the gas sampling area can be determined by capturing static or dynamic images. Referring to Figure 3 , in some embodiments, the sampling area identification element 50 includes a visual camera 51. The visual camera 51 can capture an image of the inspected goods G before the gas sampling assembly 31 performs gas sampling on the inspected goods G, and determine the location of the gas sampling area by recognizing the image. Accordingly, the gas sampling assembly 31 can be further adjusted to the sampling position corresponding to the gas sampling area.

[0121] The gas sampling assembly 31 can be adjusted by moving the carrier 10 and / or by the synchronization mechanism 40. Referring to FIG4 , for a mounting member 41 including a base 411 with an outrigger arm 412, the gas sampling assembly 31 can be adjusted by adjusting the position of the outrigger arm 412 relative to the base 411 in the height direction z or in the direction y toward the inspected cargo G. The position of the base 411 relative to the support 42 can also be adjusted in conjunction with this.

[0122] 2 , the controller 60 may be signal-connected to the sampling region identification element 50 so as to issue instructions to the carrier 10 or the synchronization mechanism 40 to adjust the position of the gas sampling assembly 31 according to the identification result of the sampling region identification element 50 .

[0123] Figure 5 is a schematic diagram of the side of the cargo inspected according to some embodiments of the cargo inspection device of the present disclosure; Figure 6 is a schematic diagram of the negative pressure structure and the positive pressure structure in the gas sampling assembly acting on the vent holes on the outer wall of the container according to some embodiments of the cargo inspection device of the present disclosure. Referring to Figure 6, in some embodiments, the gas sampling assembly 31 includes a negative pressure structure 311. The negative pressure structure 311 is configured to absorb the gas in the gas sampling area of ​​the inspected cargo G through negative pressure. The negative pressure structure 311 may include a gas hood connected to a device capable of generating a negative pressure effect (such as a gas sampling pump, etc.). The gas hood can cover the gas sampling area of ​​the inspected cargo G and suck the gas in the gas sampling area by applying negative pressure.

[0124] With reference to Figures 5 and 6 , in some embodiments, the inspected cargo G includes a container CA containing an item IT. The container CA has a cavity CH for containing the item IT. The gas sampling area includes a plurality of vents GV located on the outer wall of the container CA and connected to the cavity CH. The container CA may be a cargo box, a container, or the cargo compartment of a truck.

[0125] The negative pressure structure 311 is configured to draw gas from the gas sampling area of ​​the inspected cargo G through a portion of the plurality of vents GV. Accordingly, referring to the gas flow direction indicated by the thick black arrows in FIG6 , the negative pressure structure 311 can be positioned outside a portion of the vents GV to collect gas from within the container CA through those vents GV.

[0126] In order to improve the collection efficiency, referring to Figure 6, the gas sampling assembly 31 may also include a positive pressure structure 312. Referring to the gas flow direction indicated by the thick black arrow in Figure 6, the positive pressure structure 312 is configured to fill the cavity CH with positive pressure gas through another part of the multiple air vents GV. The positive pressure structure 312 may include an air hood connected to a device that can generate a positive pressure effect (such as an air compressor, etc.). By filling the cavity CH with positive pressure gas such as air, the gas sampling area of ​​the inspected cargo G can be effectively promoted to be collected more quickly by the negative pressure structure 311. Correspondingly, it is also beneficial to reduce the negative pressure requirements for the negative pressure structure 311, thereby reducing energy consumption.

[0127] In Figures 5 and 6 , multiple vents GV are located on the outer wall of container CA, and can be distributed on the same side or different sides. In embodiments where the negative pressure structure 311 and the positive pressure structure 312 act on the vents GV located on the outer wall of container CA adjacent to the cabin 11 and on the outer wall of container CA away from the cabin 11, respectively, the negative pressure structure 311 and the positive pressure structure 312, as well as the synchronization mechanism connected thereto, can be located on the cabin 11 and the arm 12, respectively.

[0128] 4 , in some embodiments, the radiation scanning assembly 21 includes a radiation source 211 and a detector 212. The radiation source 211 is disposed in the cabin 11. For example, in FIG4 , the radiation source 211 is disposed within the cabin 11. In other embodiments, the radiation source 211 may also be disposed on an outer wall of the cabin 11, or elsewhere.

[0129] Detectors 212 are mounted on the boom 12 and are configured to detect signals generated when radiation emitted by the radiation source 211 impacts the inspected cargo G. For the boom 12 shown in FIG4 , the radiation scanning assembly 21 may include multiple detectors 212 , which may be arranged on the horizontal detection arm 122 and the vertical detection arm 123 of the boom 12. This allows the radiation beam formed by the radiation source 211 to cover the multiple detectors 212 on the horizontal detection arm 122 and the vertical detection arm 123, thereby enabling radiation scanning of the inspected cargo.

[0130] In some embodiments, the detector 212 includes a transmission detector for performing transmission detection on the inspected cargo G to meet the requirements of cargo transmission detection. The transmission detector is located on the side of the inspected cargo G away from the radiation source, that is, the transmission detector and the radiation source are located on opposite sides of the inspected cargo G. In some embodiments, the detector 212 includes a backscatter detector for performing backscatter detection on the inspected cargo G to meet the requirements of cargo backscatter detection. The backscatter detector is located on the side of the inspected cargo G adjacent to the radiation source, that is, the backscatter detector and the radiation source are located on the same side of the inspected cargo G.

[0131] 2 , in some embodiments, the scanning imaging inspection device 20 further includes an imaging component 22 . The imaging component 22 is disposed on the carrier 10 and connected to the ray scanning component 21 , and can obtain a scanning image of the inspected cargo G based on the detection signal of the detector 212 .

[0132] Some inspection examples based on the aforementioned cargo inspection equipment embodiment are described below.

[0133] In one inspection example, the gas sampling assembly 31 is first activated for gas sampling. During the gas sampling process, the radiation scanning assembly 21 is then activated for radiation scanning. During the radiation scanning process, the radiation scanning assembly 21 and the inspected cargo G move relative to each other, while the synchronization mechanism 40 maintains the gas sampling assembly 31 stationary relative to the inspected cargo G. This allows the inspected cargo G to undergo both gas sampling and radiation scanning during a portion of the inspection process.

[0134] More specifically, the gas sampling area of ​​the inspected goods G can be determined by a sampling area identification element (visual camera, single-line laser or multi-line laser, etc.), and the moving speed of the carrier can be controlled according to the obtained moving speed of the inspected goods G (for example, determined by the detection results of a visual camera, light curtain or single-line / multi-line laser, etc., or determined by receiving speed information sent by the inspected goods G itself) so that the relative movement between the carrier and the inspected goods is at a preset rate.

[0135] The gas sampling assembly 31 is adjusted to a sampling position corresponding to the gas sampling area of ​​the inspected cargo G, and gas sampling is started before the X-ray scanning begins. The gas sample collected by the gas sampling assembly 31 is processed and analyzed by the odor analysis assembly 31 .

[0136] Based on the odor analysis results obtained by the odor analysis component 31, for example, if an odor such as an explosive is identified (i.e., the type of suspect is preliminarily determined based on the odor), the controller adjusts the scanning mode (e.g., transmission mode alone, or transmission mode and backscattering mode) and / or beam output mode (e.g., single-energy, dual-energy, or multi-energy) of the X-ray scanning component 21. Furthermore, the controller can also adjust the carrier's operating speed to reduce the relative movement rate between the carrier and the inspected cargo, thereby increasing the detection time at each inspection location on the cargo during X-ray scanning to improve imaging quality. This, in turn, increases the gas sampling time, thereby facilitating the accuracy and reliability of the odor analysis results.

[0137] During the inspection process, the gas sampling assembly 31 can continuously sample gas at a single sampling location, or it can perform gas sampling at at least two sampling locations on the inspected cargo G in separate time periods. That is, after sampling at one sampling location, the gas sampling assembly 31 is adjusted to another sampling location for sampling. Based on the analysis results of the odor analysis assembly 31, the controller can further adjust the scanning mode and / or beam output method of the X-ray scanning assembly.

[0138] Figure 7 is a schematic diagram of the structure of some embodiments of the inspection method disclosed herein. Referring to the cargo inspection equipment of the aforementioned embodiments and Figure 7 , embodiments of the present disclosure also provide an inspection method for the cargo inspection equipment of the aforementioned embodiments. This inspection method includes steps S1 and S2. Both steps S1 and S2 can be implemented by executing instructions via a controller. Accordingly, the controller can coordinate and control the various components of the cargo inspection equipment through communication with them.

[0139] In step S1 , during the cargo inspection process, the carrier 10 and the inspected cargo G are moved relative to each other along a preset direction, and the radiation scanning component 21 of the scanning imaging inspection device 20 scans the inspected cargo G through radiation.

[0140] In step S2 , the gas sampling component 31 of the odor detection device 30 performs gas sampling on the inspected cargo G, and the radiation scanning process implemented by the radiation scanning component 21 and the gas sampling process of the gas sampling component 31 at least partially overlap in time.

[0141] This embodiment allows the radiation scanning process performed by the radiation scanning assembly to at least partially overlap with the gas sampling process performed by the gas sampling assembly, enabling a certain degree of integration between the scanning imaging inspection process and the odor sniffing inspection process. Compared to related art methods that perform scanning imaging inspection and odor sniffing inspection separately in a serial manner, this disclosed embodiment can save inspection time, improve inspection efficiency, and contribute to improving the overall efficiency of cargo transportation.

[0142] In some embodiments, the inspection method further includes: during the movement of the ray scanning assembly 21 with the carrier 10 relative to the inspected goods G and the scanning of the inspected goods G, the gas sampling assembly 31 is kept relatively stationary relative to the inspected goods G or its displacement relative to the inspected goods G is kept within a preset displacement difference range by the synchronization mechanism 40, so that the gas sampling assembly 31 can perform gas sampling on the inspected goods G.

[0143] In some embodiments, the synchronization mechanism 40 has a mounting member 41 for mounting the gas sampling assembly 31. The steps of maintaining the gas sampling assembly 31 relatively stationary relative to the inspected goods G or maintaining its displacement relative to the inspected goods G within a preset displacement difference range through the synchronization mechanism 40 include: when the carrier 10 moves relative to the inspected goods G in a preset direction at a preset rate, the mounting member 41 moves in the opposite direction of the preset direction, at a preset rate or at a rate whose difference from the preset rate is within a preset rate difference range.

[0144] In some embodiments, before the gas sampling assembly 31 of the odor detection device 30 performs gas sampling on the inspected cargo G, the inspection method further includes: identifying the gas sampling area of ​​the inspected cargo G by the sampling area identification element 50 so as to adjust the gas sampling assembly 31 to a sampling position corresponding to the gas sampling area.

[0145] FIG8 is a schematic diagram of a process for adjusting a gas sampling assembly according to some embodiments of the inspection method disclosed herein. Referring to FIG6 , in some embodiments, the inspected cargo G includes a container CA for accommodating an item IT, the container CA having a cavity CH for accommodating the item IT, and the gas sampling area includes a vent GV located on the outer wall of the container CA and connected to the cavity CH. Referring to FIG8 , the step of identifying the gas sampling area of ​​the inspected cargo G may include step S3. In step S3, the position coordinates of the vent GV are identified, and the position coordinates include a first coordinate value on a first coordinate axis parallel to a preset direction (e.g., the x-axis in FIG5 ) and a second coordinate value on a second coordinate axis parallel to the plane where the outer wall of the container CA is located and perpendicular to the first coordinate axis (e.g., the z-axis in FIG5 ).

[0146] Accordingly, the step of adjusting the gas sampling assembly 31 to the sampling position corresponding to the gas sampling area may include step S41 and step S42.

[0147] In step S31, the gas sampling assembly 31 is adjusted to be the same as the first coordinate value or within a preset difference range with the first coordinate value in a direction parallel to the first coordinate axis through relative movement of the carrier 10 and the inspected goods G along a preset direction.

[0148] In step S32, before the carrier 10 and the inspected goods G move relative to each other in a preset direction or during the relative movement in the preset direction, the gas sampling component 31 is adjusted in a direction parallel to the second coordinate axis to be the same as the second coordinate value or within a preset difference range with the second coordinate value.

[0149] In each of the above embodiments, the inspection method may further include: outputting, by the imaging component 22 of the scanning imaging inspection device 20, a scanned image of the inspected cargo G obtained based on the detection signal of the radiation scanning component 21, and outputting, by the odor analysis component 32 of the odor inspection device 30, an analysis result of processing and analyzing the gas sample collected by the gas sampling component 31.

[0150] For cargoes such as containers, the embodiments of the present disclosure can achieve, during a single inspection process, not only obtaining scanning images of the interior of cargoes such as containers (such as X-ray scanning images, etc.), but also obtaining odor analysis results of volatile substances in cargoes such as containers (such as odor sniffing substance identification spectra that can identify prohibited items, etc.), thereby greatly improving inspection efficiency.

To avoid obscuring the concept of the present disclosure, some details known in the art have not been described. Based on the above description, those skilled in the art can fully understand how to implement the technical solutions disclosed herein.
