Description

TECHNICAL FIELD

[0001] The present disclosure relates to the field of inspection, and in particular, to a cargo inspection device and an inspection method thereof. BACKGROUND

[0002] In a cargo inspection scenario such as customs, health quarantine and inspection of cargo personnel are involved. In some related technologies of customs and inspection and quarantine, smell in a container is sniffed. A specific operation mode can include manually inserting a probe of a gas sniffing instrument from a container door gap to collect container gas, and even opening the container door for sampling of the container gas, if necessary, so as to analyze the gas to obtain material attribute information of the cargo. In a cargo inspection scenario such as customs, visual image generation processing of a cargo vehicle based on an X-ray cargo vehicle inspection system is also involved.

[0003] For an inspection scenario involving X-ray imaging inspection and smell sniffing, some related technologies use one or more fixed position installed gas suction sampling devices on an X-ray imaging inspection system, and collect the smell in the container before or after X-ray imaging inspection to assist in judging the material attribute of the cargo. SUMMARY

[0069] Various exemplary embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings. The description of the exemplary embodiments is merely illustrative in nature and is in no way intended to limit the disclosure, its application or uses. The present disclosure can be implemented in numerous different forms, not limited to the embodiments described herein.

It should also be understood that the terms defined in general dictionaries should be interpreted as having meanings consistent with their meanings in the context of the relevant art, and should not be interpreted in an idealized or extremely formalized sense, unless otherwise specifically defined herein.

[0073] The technologies, methods, and devices known to those of ordinary skill in the relevant art can not be discussed in detail, but should be considered as part of the specification where appropriate.

[0074] For the inspection scene where X-ray imaging inspection and odor sniffing exist, some related technologies use one or several fixed position installed odor sampling devices on 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 goods.

[0075] The X-ray imaging inspection and odor sniffing inspection in the related art are two independent processes in series, and need two independent sets of equipment, which has high cost, long inspection time and low efficiency, thereby affecting the overall efficiency of the goods transportation; and the odor sniffing inspection needs personnel operation, which is heavy work and has low efficiency, and has certain safety hazards to the health of the personnel.

[0076] Therefore, embodiments of the present disclosure provide a goods inspection device and an inspection method thereof, which can meet the needs of both the X-ray imaging inspection and the odor sniffing inspection, and improve the inspection efficiency.

[0077] Figure 1 is a structural schematic diagram of some embodiments of the goods inspection device according to the present disclosure. Figure 2 is a structural schematic diagram of some other embodiments of the goods inspection device according to the present disclosure. Referring to Figure 1 and Figure 2The embodiment of the present disclosure provides a cargo inspection device, which comprises 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 cargo G to be inspected along a preset direction during the cargo inspection process. The scanning imaging inspection device 20 has a radiation scanning assembly 21 for scanning the cargo G to be inspected by radiation. The odor inspection device 30 has a gas sampling assembly 31 for sampling the gas of the cargo G to be inspected. The radiation scanning assembly 21 and the gas sampling assembly 31 are both arranged on the carrier 10, and the radiation scanning process realized by the radiation scanning assembly 21 and the gas sampling process of the gas sampling assembly 31 at least partially coincide in time.

[0078] The embodiment of the present disclosure can realize the integration of the scanning imaging inspection process and the odor sniffing inspection process to a certain extent by arranging the radiation scanning assembly of the scanning imaging inspection device and the gas sampling assembly of the odor inspection device on the carrier moving relative to the cargo to be inspected, and making the radiation scanning process realized by the radiation scanning assembly and the gas sampling process of the gas sampling assembly at least partially coincide in time.

[0079] Compared with the scanning imaging inspection and odor sniffing inspection respectively performed in a serial manner in the related art, the embodiment of the present disclosure can save the inspection time, improve the inspection efficiency, be beneficial to improving the overall efficiency of cargo transportation, and can reduce the number of components by arranging the radiation scanning assembly and the gas sampling assembly on the carrier, which is beneficial to reducing the cost. In addition, the odor inspection device can reduce the degree of personnel participation, reduce the adverse effects of the odor inspection process on the health of personnel, and can save the labor intensity of the participating personnel in the scanning imaging inspection process and the odor sniffing inspection process.

[0080] During the cargo inspection process, the carrier 10 moves relative to the cargo G to be inspected. In some embodiments, the relative movement of the carrier 10 and the cargo G to be inspected means that the carrier 10 remains stationary, and the cargo G to be inspected moves by itself or is driven to move by other mechanisms. In other embodiments, the relative movement of the carrier 10 and the cargo G to be inspected means that the cargo G to be inspected remains stationary, and the carrier 10 moves by itself or is driven to move by other mechanisms. In addition, the relative movement of the carrier 10 and the cargo G to be inspected can also mean that the carrier 10 and the cargo G to be inspected both move, and the moving speeds and / or moving directions are different.

[0081] In order to realize the movement of the carrier 10 during the transition, transportation or cargo inspection process, in some embodiments, the carrier 10 comprises a drivable vehicle body so as to travel on a site or a road; in other embodiments, the carrier 10 can have a walking device, such as a roller assembly capable of running on a track or a site surface.

[0082] The inspected goods G can be in various forms, such as a package, a cargo box, a container or a vehicle. The vehicle can include various types of motor vehicles (e.g., a sedan, a bus, a van, a container truck, etc.) or trains (e.g., a passenger train or a freight train, etc.). Taking the container truck as an example, the inspected goods G can be a container carried by the container truck, or the container truck including the container.

[0083] The scanning imaging inspection device 20 includes a ray scanning assembly 21 for scanning the inspected goods G by rays. The rays herein can be X rays or gamma rays. In some embodiments, the ray scanning assembly 21 can include a ray source for outputting rays of a preset energy, and a detector configured to detect the rays after acting on the inspected goods G and form a detection signal.

[0084] For example, when the ray source emits X rays, the X rays pass through the inspected goods G from one side of the inspected goods G and are attenuated, and then are detected by the detector located at the other side of the inspected goods G, thereby forming a transmission detection signal. For another example, when the ray source emits X rays, backscattering signals generated by the X rays in the inspected goods G are detected by the detector at the same side as the ray source, thereby forming a backscattering detection signal.

[0085] Taking the container truck as an example, the carrier 10 provided with the ray scanning assembly 21 can move along the length direction of the container truck on the track on the site, so that the ray scanning assembly 21 performs ray scanning on the container truck from the front to the rear or from the rear to the front.

[0086] Reference Figure 1 and Figure 2 In some embodiments, the scanning imaging inspection device 20 further includes an imaging assembly 22 connected with the ray scanning assembly 21. The imaging assembly 22 can be connected with the ray scanning assembly 21 in a wired or wireless manner to obtain the detection signal obtained by the ray scanning assembly 21 through ray scanning, and obtain a scanning image of the inspected goods G according to the detection signal. In this way, the shape, contour and color reflected in the scanning image can be used to determine the properties of the goods inside the inspected goods.

[0087] As shown in Figure 1 The imaging assembly 22 can be provided outside the carrier 10 to be independent of the carrier 10. For example, the imaging device 22 can be an upper computer or a remote server in wireless communication with the ray scanning assembly 21 and having an imaging function. In this way, it is beneficial to simplify the structure carried on the carrier 10, reduce the weight, reduce the energy consumption for driving the movement of the carrier 10, and also enable remote control and monitoring of the ray scanning inspection process.

[0088] In other embodiments, the imaging assembly 22 can also beFigure 2 Correspondingly, the imaging assembly 22 also moves, transits and transports together with the carrier 10, achieving greater integration, facilitating the reduction of the device size and the improvement of the use flexibility.

[0089] The odor inspection device 30 comprises a gas sampling assembly 31. The gas sampling assembly 31 is used for sampling the gas of the inspected goods G. Here, the gas can be the volatile gas on or in the surface of the inspected goods G, such as the gas volatilized by the goods in the container. Through the gas sampling of the inspected goods G, the gas sample can be further processed and analyzed by the odor analysis assembly 32, so as to achieve the detection of, for example, harmful chemicals, explosives and the like.

[0090] Reference Figure 1 And Figure 2 In some embodiments, the odor inspection device 30 further comprises an odor analysis assembly 32. The odor analysis assembly 32 can process and analyze the gas sample collected by the gas sampling assembly 31. For example, the odor analysis assembly 32 can use an odor sniffing device to concentrate and analyze the collected gas, so as to obtain an analysis result. Here, the odor analysis assembly 32 can be based on but not limited to mass spectrometry technology, ion mobility technology, gas chromatography-ion mobility spectrometry and its combined technology, and can achieve qualitative and quantitative analysis and detection of toxic and harmful gases, volatile hazardous chemicals, odor of plants and animal products and food, volatile drugs, easily-made toxic chemicals and explosives and the like.

[0091] The gas sample collected by the gas sampling assembly 31 can be transported from the gas sampling assembly 31 to the odor analysis assembly 32 through a conveying pipeline, or can be manually or by other devices transferred to the odor analysis assembly 32 after collection.

[0092] As Figure 2 shown, the odor analysis assembly 32 can be arranged outside the carrier 10, so as to be arranged independently of the carrier 10. For example, the odor analysis assembly 32 can be arranged in a monitoring room or a laboratory outside the site, and receives the gas sample manually or by other devices. In this way, it is beneficial to simplify the structure carried on the carrier 10, reduce the weight, reduce the energy consumption of driving the carrier 10 to move, and can achieve more abundant odor analysis functions without being limited by the structural requirements of the carrier 10.

[0093] In other embodiments, the odor analysis assembly 32 can also be arranged on the carrier 10 as Figure 2 shown. Correspondingly, the odor analysis assembly 32 also moves, transits and transports together with the carrier 10, achieving greater integration, facilitating the reduction of the device size and the improvement of the use flexibility. The odor analysis assembly 32 can be directly or through a pipeline connected with the gas sampling assembly 31, so as to obtain the gas sample collected by the gas sampling assembly 31.

[0094] In the present embodiment, the radiation scanning process implemented by the radiation scanning assembly 21 at least partially coincides in time with the gas sampling process implemented by the gas sampling assembly 31. The radiation scanning process can fully coincide with the gas sampling process, or can partially coincide with the gas sampling process. The time period during which the radiation scanning process and the gas sampling process coincide can effectively save inspection time, and can improve the overall inspection efficiency compared with the radiation scanning process and the gas sampling process that do not coincide in time.

[0095] For example, the radiation scanning assembly 21 is started to perform radiation scanning first, and the gas sampling assembly 31 is started to perform gas sampling during the radiation scanning process, and the gas sampling process is stopped before, simultaneously with, or after the end of the radiation scanning process, as the relative motion between the carrier 10 and the inspected goods G.

[0096] For another example, the gas sampling assembly 31 is started to perform gas sampling first, and the radiation scanning assembly 21 is started to perform radiation scanning during the gas sampling process, and the radiation scanning process is stopped before, simultaneously with, or after the end of the gas sampling process, as the relative motion between the carrier 10 and the inspected goods G.

[0097] The radiation scanning of the radiation scanning assembly 21 and the gas sampling of the gas sampling assembly 31 can be started simultaneously, and the radiation scanning process can be stopped before, simultaneously with, or after the end of the gas sampling process, as the relative motion between the carrier 10 and the inspected goods G.

[0098] In order to more effectively control the radiation scanning process implemented by the radiation scanning assembly 21 to at least partially coincide in time with the gas sampling process implemented by the gas sampling assembly 31, the present embodiment can further comprise a controller 60. Figure 1 In some embodiments, the goods inspection apparatus can further comprise a controller 60, which can be signal-connected with at least one of the carrier 10, the scanning imaging inspection device 20, and the odor inspection device 30. The controller 60 can coordinate the radiation scanning process and the gas sampling process in the goods inspection process by issuing instructions to at least one of the carrier 10, the scanning imaging inspection device 20, and the odor inspection device 30.

[0099] In some embodiments, the controller 60 can further issue instructions to the imaging assembly 22 and the odor analysis assembly 32, so that the imaging assembly 22 outputs the scanning image of the inspected goods G obtained according to the detection signal of the radiation scanning assembly 21 in the goods inspection process, and so that the odor analysis assembly 32 outputs the analysis result of processing and analyzing the gas sample collected by the gas sampling assembly 31 in the goods inspection process. The controller 60 can also issue instructions to the carrier 10 to move or stop the carrier 10 relative to the inspected goods G.

[0100] Figure 2The controller 60 and its signal connection relationship with the carrier 10, the scanning imaging inspection device 20 and the odor inspection device 30 can also be applicable to the embodiment shown in Figure 2

[0101] The controller 60 can be implemented by one or more Application Specific Integrated Circuit (ASIC), Digital Signal Processor (DSP), Programmable Logic Device (PLD), Field Programmable Gate Array (FPGA), processor, microcontroller, microprocessor or other electronic elements. The controller 60 can be arranged on the carrier 10 or arranged on a remote control platform server independently of the carrier 10.

[0102] Reference Figure 3 In some embodiments, the cargo inspection device further comprises a synchronization mechanism 40. The synchronization mechanism 40 is connected with the gas sampling assembly 31 and is configured to keep the gas sampling assembly 31 relatively stationary relative to the inspected cargo G or keep the displacement of the gas sampling assembly 31 relative to the inspected cargo G within a preset displacement difference range during the process that the radiation scanning assembly 21 moves relative to the inspected cargo G along with the carrier 10 and scans the inspected cargo G.

[0103] Through the synchronization of the synchronization mechanism 40 to the gas sampling assembly 31, the gas sampling assembly 31 can be kept relatively stationary (i.e. the relative displacement is 0) or within a preset displacement difference range relative to the inspected cargo G during the gas sampling process, so that the gas sampling assembly 31 can stably and continuously realize the gas sampling of the inspected cargo G. Keeping relatively stationary is conducive to further improving the stability and continuity of gas sampling, and keeping the displacement of the gas sampling assembly 31 relative to the inspected cargo G within a preset displacement difference range is conducive to reducing the higher requirement for the synchronization accuracy of the synchronization mechanism 40.

[0104] Here, the preset displacement difference range can be determined according to factors such as the size of the gas sampling assembly 31 and the size of the sampling area of the inspected cargo G. For the inspected cargo G with a smaller air hole, during the gas sampling process, the larger size of the gas sampling assembly 31 allows a small displacement relative to the air hole, which still ensures the stable and continuous performance of the gas sampling. The preset displacement difference range can include the displacement difference range in the relative movement direction of the carrier 10 and the inspected cargo G, or the displacement difference range in the direction perpendicular to the direction. ​

[0105] Referring to Figure 4 , the controller 60 can be signal connected with the synchronization mechanism 40, and coordinate the synchronization of the synchronization mechanism 40 to the gas sampling assembly 31 by issuing instructions to the synchronization mechanism 40. The synchronization mechanism 40 can adopt but is not limited to a linear motor, a gear rack, a screw guide rail, a joint robot, etc. to move in at least one direction (for example, in the orthogonal x, y, z axis directions) to realize the synchronization operation, so as to realize the accurate positioning of the gas sampling assembly 31 relative to the gas sampling area of the inspected goods G under the control of the controller.

[0106] Figure 3 and Figure 3 are schematic diagrams of the application scene of some embodiments of the goods inspection equipment according to the present disclosure from the overhead angle and the eye level angle respectively. Referring to Figure 3 , in some embodiments, the synchronization mechanism 40 has a mounting member 41 mounting the gas sampling assembly 31, and is configured to move the mounting member 41 in the opposite direction of the preset direction at the preset speed or at a speed within the preset speed difference range from the preset speed when the carrier 10 moves in the preset direction relative to the inspected goods G at the preset speed.

[0107] For example, in Figure 4 , the container truck as the inspected goods G remains stationary, and the carrier 10 moves in the opposite direction of the direction x (parallel to the length direction of the container truck) at the speed a, so as to perform the continuous ray scanning of the ray scanning assembly 21 from the front to the tail of the truck. In this process, the gas sampling assembly 31 mounted by the mounting member 41 has docked the vent hole of the container truck, and under the synchronization of the synchronization mechanism 40, the mounting member 41 moves relative to the carrier 10 in the direction x at the speed b. The speed b is equal to the speed a, so that the mounting member 41 and the gas sampling assembly 31 remain stationary with the container truck, so that the gas sampling assembly 31 continuously docks with the vent hole of the container truck, thereby ensuring the continuity and stability of the gas collection.

[0108] The speed b can also be different from the speed a, and the difference is within the preset speed difference range, so that the displacement of the gas sampling assembly 31 relative to the inspected goods G during the gas sampling process is kept within the preset displacement difference range.

[0109] Referring to Figure 4 and Figure 4 , in some embodiments, the carrier 10 includes a cabin 11 and an arm support 12. The cabin 11 can realize the carrying of part of the components of the scanning imaging inspection device 20 and the odor inspection device 30, and connects and supports the arm support 12. The arm support 12 can be surrounded with the cabin 11 to form an inspection channel for the inspected goods G to pass through.

[0110] In Figure 5In some embodiments, the arm support 12 can include a support arm 121, a horizontal detection arm 122 connected with the support arm 121, and a vertical detection arm 123 connected with the horizontal detection arm 122, and the support arm 121 is fixedly or rotatably arranged on the cabin 11. Correspondingly, the inspection channel can be enclosed by a door-shaped frame formed by the outer wall of the cabin 11 and the arm support 12. The cabin 11 and the arm support 12 can be moved along the extension direction of the track by cooperating with the track arranged on the ground through the rollers.

[0111] The synchronization mechanism 40 can be arranged on the cabin 11 and / or the arm support 12. In some embodiments, the synchronization mechanism 40 is arranged on the cabin 11 and located on the top surface of the cabin 11. In other embodiments, the synchronization mechanism 40 can also be arranged on the arm support 12, such as the horizontal detection arm 122 or the vertical detection arm 123, so as to collect the gas from the top vent of the inspected goods G or the vent on the side away from the cabin 11. Figure 4

[0112] Referring to FIG. 1, the synchronization mechanism 40 can be arranged on the cabin 11 and / or the arm support 12. In some embodiments, the synchronization mechanism 40 is arranged on the cabin 11 and located on the top surface of the cabin 11. In other embodiments, the synchronization mechanism 40 can also be arranged on the arm support 12, such as the horizontal detection arm 122 or the vertical detection arm 123, so as to collect the gas from the top vent of the inspected goods G or the vent on the side away from the cabin 11.

The mounting 41 is movably arranged on the support 42. The gas sampling assembly 31 is mounted on the mounting 41.

[0113] The support 42 can be connected or fixed on the cabin 11 and / or the arm support 12 by a connecting member, welding or other methods, or can be integrally formed with the cabin 11 or the arm support 12. The mounting 41 can adopt various structural forms, such as the one shown in FIG. 2, which includes a seat body 411 that can slide integrally on the top wall of the cabin 11, and the seat body 411 is provided with a fixed or movable outer extension arm 412, and the end of the outer extension arm 412 can mount the gas sampling assembly 41. In some embodiments, the mounting 41 can form a sliding fit with the slide rail located on the top wall of the cabin 11. That is, the mounting 41 and the support 42 are slidably fitted in a predetermined direction. Here, the extension direction of the slide rail can be parallel to the movement direction of the carrier relative to the inspected goods G. In this way, the mounting 41 can move integrally along the support 42, so that the gas sampling assembly 31 can be more stably kept relatively stationary or the displacement relative to the inspected goods G is kept within a predetermined displacement difference range during the gas sampling process.

[0114] In other embodiments, the mounting 41 can include a multi-joint mechanical arm, and part of the arm segments of the mechanical arm can move relative to the support 42 to achieve the effect that the gas sampling assembly 31 is kept relatively stationary or the displacement relative to the inspected goods G is kept within a predetermined displacement difference range during the gas sampling process. The mounting 41 in the form of a multi-joint mechanical arm can have more flexible functions and stronger scene adaptability. ​​

[0115] Reference is made to Figure 3 and Figure 4 In some embodiments, the cargo inspection apparatus further comprises a sampling area identification element 50. The sampling area identification element 50 can be arranged outside the carrier 10, for example on the ground, or on the carrier 10. The sampling area identification element 50 is configured to identify a gas sampling area of the cargo under inspection G, so that the carrier 10 and / or the synchronization mechanism 40 adjusts the gas sampling assembly 31 to a sampling position corresponding to the gas sampling area.

[0116] The identification of the gas sampling area of the cargo under inspection G by the sampling area identification element 50 can enable the gas sampling assembly 31 to be conveniently adjusted to the sampling position corresponding to the gas sampling area, saving the workload of manually adjusting the carrier position or the gas sampling assembly position, and improving the inspection efficiency.

[0117] Here, the gas sampling area of the cargo under inspection G can be the outside of the cargo under inspection G, for example, the position adjacent to one side of the carrier 10 or away from one side of the carrier 10 of the cargo under inspection G, or the lower side or the upper side of the cargo under inspection G. The gas sampling area of the cargo under inspection G can also be the inside of the cargo under inspection G or a part in communication with the inside of the cargo under inspection G.

[0118] For some cargo under inspection G, the gas sampling area has certain visual identification, that is, the specific position of the gas sampling area can be determined by shooting static or dynamic images. Reference is made to Figure 2 In some embodiments, the sampling area identification element 50 comprises a visual camera 51. The visual camera 51 can acquire images of the cargo under inspection G before the gas sampling assembly 31 samples the cargo under inspection G, and determine the position of the gas sampling area by identifying the images. Accordingly, the gas sampling assembly 31 can be further adjusted to the sampling position corresponding to the gas sampling area.

[0119] Here, the adjustment of the gas sampling assembly 31 can be through the movement of the carrier 10 and / or the movement of the gas sampling assembly 31 by the synchronization mechanism 40. Reference is made to Figure 5 For the mounting 41 comprising the seat body 411 provided with the overhanging arm 412, the gas sampling assembly 31 can be adjusted by adjusting the position of the overhanging arm 412 relative to the seat body 411 in the height direction z or the direction y pointing to the cargo under inspection G, and the position of the seat body 411 relative to the support 42 can also be adjusted in coordination.

[0120] Reference is made to Figure 6 The controller 60 can be in signal connection with the sampling area identification element 50, so as to issue instructions to the carrier 10 or the synchronization mechanism 40 according to the identification result of the sampling area identification element 50 to realize the position adjustment of the gas sampling assembly 31.

Reference is made to Figure 6 In some embodiments, the gas sampling assembly 31 comprises a negative pressure structure 311. The negative pressure structure 311 is configured to draw the gas in the gas sampling region of the inspected cargo G by negative pressure. The negative pressure structure 311 can comprise a gas hood connected with a device capable of generating a negative pressure effect (e.g. a gas sampling pump, etc.). The gas hood can be hooded over the gas sampling region of the inspected cargo G to draw the gas in the gas sampling region by applying negative pressure.

[0122] Reference is made to Figure 6 and Figure 6 In some embodiments, the inspected cargo G comprises a container CA containing the item IT, the container CA has a cavity CH for containing the item IT, and the gas sampling region comprises a plurality of vent holes GV located on the outer wall of the container CA and communicating with the cavity CH. The container CA here can be a cargo box, a container or a cargo compartment of a truck, etc.

Accordingly, reference is made to Figure 6 The negative pressure structure 311 can be hooded outside a portion of the vent holes GV to achieve the collection of the gas inside the container CA via the portion of the vent holes GV, according to the direction of the gas flow represented by the thick black arrows in

[0124] In order to improve the collection efficiency, reference is made to Figure 5 The gas sampling assembly 31 can further comprise a positive pressure structure 312. Reference is made to Figure 6 The positive pressure structure 312 is configured to fill the cavity CH with positive pressure gas through another portion of the plurality of vent holes GV, according to the direction of the gas flow represented by the thick black arrows in

For the embodiments in which the negative pressure structure 311 and the positive pressure structure 312 act on the vent holes GV located on the outer wall of the side of the container CA adjacent to the cabin 11 and the vent holes GV located on the outer wall of the side of the container CA away from the cabin 11 respectively, the negative pressure structure 311 and the positive pressure structure 312 and the synchronous mechanism connected thereto can be arranged on the cabin 11 and the arm support 12 respectively.

[0126] Reference Figure 4 In some embodiments, the ray scanning assembly 21 comprises a ray source 211 and a detector 212. The ray source 211 is arranged on the cabin 11. For example, in the embodiment shown in FIG. 1, the ray source 211 is arranged on the outer wall of the cabin 11. Figure 2 In some embodiments, the ray source 211 is arranged on the outer wall of the cabin 11. In other embodiments, the ray source 211 can also be arranged at other positions such as on the outer wall of the arm support 12.

[0127] The detector 212 is arranged on the arm support 12 and is configured to detect the signal when the ray emitted by the ray source 211 acts on the inspected goods G. For the embodiment shown in FIG. 1, the detector 212 is arranged on the outer wall of the arm support 12. Figure 7 For the embodiment shown in FIG. 1, the ray scanning assembly 21 can comprise a plurality of detectors 212, which can be arranged on the horizontal detection arm 122 and the vertical detection arm 123 of the arm support 12. In this way, the ray beam plane formed by the ray source 211 can cover the plurality of detectors 212 on the horizontal detection arm 122 and the vertical detection arm 123, thereby realizing the ray scanning detection of the inspected goods.

[0128] In some embodiments, the detector 212 comprises a transmission detector for transmission detection of the inspected goods G, so as to meet the need for transmission detection of the goods. The transmission detector is located on the side of the inspected goods G away from the ray source, i.e. the transmission detector and the ray source are located on the two sides of the inspected goods G. In some embodiments, the detector 212 comprises a backscatter detector for backscatter detection of the inspected goods G, so as to meet the need for backscatter detection of the goods. The backscatter detector is located on the side of the inspected goods G adjacent to the ray source, i.e. the backscatter detector and the ray source are located on the same side of the inspected goods G.

[0129] Reference Figure 7 In some embodiments, the scanning and imaging inspection device 20 further comprises an imaging assembly 22. The imaging assembly 22 is arranged on the carrier 10 and is connected with the ray scanning assembly 21, and can obtain the scanning image of the inspected goods G according to the detection signal of the detector 212.

[0130] The following describes some inspection examples based on the foregoing embodiments of the goods inspection device.

[0131] In one inspection instance, the gas sampling assembly 31 is first activated to perform gas sampling, and the ray scanning assembly 21 is activated to perform ray scanning during the gas sampling. During the ray scanning, the ray scanning assembly 21 moves relative to the inspected goods G, and the synchronization mechanism 40 keeps the gas sampling assembly 31 relatively static relative to the inspected goods G. Thus, the inspected goods G is subjected to both gas sampling and ray scanning at the same time during part of the inspection process.

[0132] More specifically, the gas sampling region of the inspected goods G can be determined by a sampling region identification element (such as a 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 result of a visual camera, light curtain, or single / multi-line laser, etc., or determined by receiving the speed information sent by the inspected goods G itself) so that the relative movement between the carrier and the inspected goods G is at a preset speed.

[0133] The gas sampling assembly 31 is adjusted to a sampling position corresponding to the gas sampling region of the inspected goods G, and the gas sampling is started before the ray scanning starts. The gas sample collected by the gas sampling assembly 31 is processed and analyzed by the odor analysis assembly 31.

[0134] According to the odor analysis result obtained by the odor analysis assembly 31, for example, when an explosive odor is identified (i.e., the type of the suspicious object is preliminarily determined according to the odor), the controller adjusts the scanning mode (for example, a single transmission mode, or a transmission mode and a backscatter mode) and / or the beam output mode (for example, single energy, dual energy, or multi-energy) of the ray scanning assembly 21. Moreover, the controller can also adjust the speed of the carrier so as to reduce the relative movement speed between the carrier and the inspected goods G, thereby increasing the detection time of each detection position of the goods during the ray scanning to improve the imaging effect, and correspondingly, the gas sampling time can also be increased, thereby improving the accuracy and reliability of the odor analysis result.

[0135] During the inspection, the gas sampling assembly 31 can continuously perform gas sampling at a single sampling position, or can perform gas sampling at at least two sampling positions of the inspected goods G in time periods. That is, after the gas sampling assembly 31 samples at one sampling position, the gas sampling assembly 31 is adjusted to another sampling position for sampling. The controller can again adjust the scanning mode and / or the beam output mode of the ray scanning assembly according to the analysis result of the odor analysis assembly 31.

[0136] Figure 8 is a structural schematic diagram of some embodiments according to the inspection method of the present disclosure. The goods inspection device and the inspection method of the above-mentioned embodiments are referred to. Figure 6The embodiments of the present disclosure further provide an inspection method of the cargo inspection device of the foregoing embodiments. The inspection method comprises steps S1 and S2. Both steps S1 and S2 can be realized by executing instructions of a controller, and the controller can realize coordination and control of various components in the cargo inspection device by communicating with the components.

[0137] In step S1, during the cargo inspection, the carrier 10 is moved relative to the inspected cargo G along a preset direction, and the radiation scanning assembly 21 of the scanning and imaging inspection device 20 is used to scan the inspected cargo G by radiation.

[0138] In step S2, the gas sampling assembly 31 of the odor inspection device 30 is used to sample gas from the inspected cargo G, and the radiation scanning process realized by the radiation scanning assembly 21 and the gas sampling process of the gas sampling assembly 31 at least partially coincide in time.

[0139] The embodiments of the present disclosure make the radiation scanning process realized by the radiation scanning assembly and the gas sampling process of the gas sampling assembly at least partially coincide in time, which can realize a certain degree of integration of the scanning and imaging inspection process and the odor sniffing inspection process. Compared with the scanning and imaging inspection and the odor sniffing inspection performed in a serial manner in the related art, the embodiments of the present disclosure can save inspection time and improve inspection efficiency, which is conducive to improving the overall efficiency of cargo transportation.

[0140] In some embodiments, the inspection method further comprises: during the movement of the radiation scanning assembly 21 relative to the inspected cargo G along with the carrier 10 and the scanning of the inspected cargo G, the gas sampling assembly 31 is kept relatively stationary relative to the inspected cargo G or the displacement of the gas sampling assembly 31 relative to the inspected cargo G is kept within a preset displacement difference range by the synchronization mechanism 40, so that the gas sampling assembly 31 samples gas from the inspected cargo G.

[0141] In some embodiments, the synchronization mechanism 40 has a mounting member 41 for mounting the gas sampling assembly 31, and the step of keeping the gas sampling assembly 31 relatively stationary relative to the inspected cargo G or keeping the displacement of the gas sampling assembly 31 relative to the inspected cargo G within a preset displacement difference range by the synchronization mechanism 40 comprises: when the carrier 10 moves relative to the inspected cargo G along a preset direction at a preset speed, the mounting member 41 moves along the opposite direction of the preset direction at the preset speed or at a speed within a preset speed difference range from the preset speed.

[0142] In some embodiments, before the gas sampling assembly 31 of the odor inspection device 30 samples gas from the inspected cargo G, the inspection method further comprises: identifying a 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.

[0143] Figure 8 is a flowchart of adjusting the gas sampling assembly according to some embodiments of the inspection method of the present disclosure. Referring to Figure 5 In some embodiments, the inspected goods G include a container CA containing the items IT, the container CA has a cavity CH for containing the items IT, and the gas sampling region includes a vent hole GV located on the outer wall of the container CA and communicating with the cavity CH. Referring to Figure 5 The step of identifying the gas sampling region of the inspected goods G can include step S3. In step S3, the position coordinates of the vent hole GV are identified, including a first coordinate value on a first coordinate axis (for example ​ x-axis in the figure) parallel to the preset direction and a second coordinate value on a second coordinate axis (for example ​ z-axis in the figure) parallel to the plane on which the outer wall of the container CA is located and perpendicular to the first coordinate axis.

[0144] Correspondingly, the step of adjusting the gas sampling assembly 31 to the sampling position corresponding to the gas sampling region can include steps S41 and S42.

[0145] In step S31, by the relative movement of the carrier 10 and the inspected goods G along the preset direction, the gas sampling assembly 31 is adjusted to the same as or within a preset difference range of the first coordinate value along the direction parallel to the first coordinate axis.

[0146] In step S32, before or during the relative movement of the carrier 10 and the inspected goods G along the preset direction, the gas sampling assembly 31 is adjusted to the same as or within a preset difference range of the second coordinate value along the direction parallel to the second coordinate axis.

[0147] In the above embodiments, the inspection method can further include outputting, by the imaging assembly 22 of the scanning and imaging inspection device 20, a scan image of the inspected goods G obtained according to the detection signal of the ray scanning assembly 21, and outputting, by the odor analysis assembly 32 of the odor inspection device 30, an analysis result of processing and analyzing the gas sample collected by the gas sampling assembly 31.

[0148] For goods such as containers, the embodiments of the present disclosure can achieve, in one inspection process, not only to obtain the scan image (such as X-ray scan image, etc.) inside the container and other goods, but also to obtain the odor analysis result (such as the odor sniffing substance identification spectrum line that can identify the prohibited items, etc.) of the volatile substances inside the container and other goods, thereby greatly improving the inspection efficiency.
