DETAILED DESCRIPTION

[0050] The technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the drawings in the embodiments of the present disclosure. The described embodiments are only some of the embodiments of the present disclosure, rather than all the embodiments. The following description of at least one exemplary embodiment is merely illustrative in nature and not intended to be limiting on the present disclosure and its applications or uses.

[0051] In the description of the present disclosure, the words "first", "second", etc. used to limit parts are only for the convenience of distinguishing the corresponding parts, and have no special meaning unless otherwise stated. Therefore, it cannot be understood as a limitation on the protection scope of the present disclosure.

[0052] In the description of the present disclosure, it should be understood that the technical features involved in different embodiments of the present disclosure can be combined with each other as long as there is no conflict. The technical features involved in different embodiments of the present disclosure will be described below.

[0053] In addition, the technical features involved in different embodiments of the present disclosure described below can be combined with each other as long as there is no conflict.

[0054] Figure 1 is a front structural schematic view of some embodiments of the cargo inspection system according to the present disclosure.

[0055] Reference is made to Figure 1 , and in conjunction with Figures 2-9 , in one aspect of the present disclosure, a cargo inspection system is provided. The cargo inspection system comprises a shore crane 100 configured to move on a track assembly 1, which can be at least two parallel tracks. The shore crane 100 comprises a first carriage 21 for moving on a first track 11 in the track assembly 1 and a second carriage 22 for moving on a second track 12 in the track assembly 1. Here the first carriage 21 and the second carriage 22 of the shore crane 100 do not limit the positional relationship between the carriages and other locations in the scene (e.g. a ship or a yard, etc.). For example, in Figure 1 , the first carriage 21 is away from the ship and the second carriage 22 is close to the ship. Alternatively, the first carriage 21 can be close to the ship and the second carriage 22 can be away from the ship.

[0056] Figure 2 is a schematic view of some embodiments of the cargo inspection system according to the present disclosure. Reference is made to Figure 1 and Figure 2 , a cargo handling area is provided between the first carriage 21 and the second carriage 22, which can mean that the cargo handling area is located within the area defined by the first carriage 21 and the second carriage 22 in both the width direction and the length direction, that is, the cargo handling area is located within the area defined by the first carriage 21 and the second carriage 22 in both the width direction and the length direction.

[0057] The tops of the first carriage 21 and the second carriage 22 are connected by a plurality of parallel main beams 23, and a hoist bridge device for hoisting cargo is arranged on the middle main beam 23, so that the shore crane 100 hoists the cargo 5 onto a transfer vehicle 6 located in the cargo handling area. The cargo 5 can be a container.

[0058] Specifically, the first gantry 21 can include a first vertical beam 211 located at the first side S1 of the shore crane 100 and a second vertical beam 212 located at the second side S2 of the shore crane 100, and the second gantry 22 can include a third vertical beam 221 located at the first side S1 of the shore crane 100 and a fourth vertical beam 222 located at the second side S2 of the shore crane 100. Each vertical beam can be located at the boundary of one side of the shore crane 100. Here, the first side S1 and the second side S2 of the shore crane 100 are only used to describe the relative position relationship between the vertical beams, and do not limit the position relationship between the vertical beams and other places in the scene (such as ships or stations, etc.). A plurality of parallel main beams 23 can be provided between the top of the first vertical beam 211 and the top of the third vertical beam 221, and between the top of the second vertical beam 212 and the top of the fourth vertical beam 222.

[0059] Figure 3 is a front structural schematic diagram according to some embodiments of the cargo inspection system of the present disclosure. Referring to Figure 3 , the cargo inspection system further comprises a radiation scanning device, which comprises a first ray source assembly 3 and a detector assembly 4. The ray source, also known as the radiation source, can emit rays for scanning the object to be inspected. The detector is used to receive the rays emitted by the ray source when scanning the object to be inspected, and then obtain the internal situation of the object to be measured through image processing. In order to enable the detector to accurately receive the rays emitted by the ray source, a plurality of rows of detectors can be used on the detector assembly and the receiving surface of the detector is directed towards the ray source. The first ray source assembly 3 is installed on the first gantry 21, and the detector assembly 4 is installed on the second gantry 22. Here, installation can mean fixed connection, so that the radiation scanning device can move together with the first gantry 21 and the second gantry 22 to move to different berths with the shore crane 100 for scanning inspection.

[0060] Referring to Figure 3 , the radiation scanning device is configured to scan and inspect the transfer trolley 6 carrying the cargo 5 between the cargo loading and unloading area and the station outside the cargo loading and unloading area. The station can be used for loading, storing and transferring of cargo, and can stack a large amount of cargo. The transfer trolley 6 can be an AGV trolley or a semi-trailer tractor, and the transfer trolley 6 travels at a predetermined speed to be inspected until the scanning is completed. In particular, there is a low-speed travel phase during the travel of the transfer trolley 6 from the cargo loading and unloading area to the departure of the cargo loading and unloading area after the transfer trolley 6 is loaded with the cargo 5, and the radiation scanning device scans the cargo 5 using the low-speed travel phase of the transfer trolley 6, which can obtain higher quality scanning images.

[0061] In order to transfer the goods 5 on the cargo ship to the yard of the port, the shore crane 100 can be moved to the loading site, the transfer vehicle 6 is moved to the goods handling area, the goods 5 are placed on the transfer vehicle 6 by the hoisting mechanism on the shore crane 100, and then the transfer vehicle 6 is driven to the yard. Correspondingly, the goods 5 in the port can also be transferred to the cargo ship. No matter which direction the transfer is, the first radiation source assembly 3 and the detector assembly 4 are located on the path of the transfer vehicle 6 carrying the goods 5 and are scanned.

[0062] According to the embodiments of the present disclosure, by mounting the first radiation source assembly 3 in the radiation scanning device on the first rack 21 and mounting the detector assembly 4 on the second rack 21, the goods inspection system can be easily added, and the scanning inspection of the goods 5 can be realized during the driving of the transfer vehicle 6 away from the shore crane, without the need to stop, thereby effectively improving the scanning inspection efficiency. In addition, the scanning inspection of the goods 5 can be realized directly during the transfer of the transfer vehicle 6, which can reduce the risk of dangerous contraband entering the yard with high stacking density of the goods 5.

[0063] In addition, by mounting the first radiation source assembly 3 on the first rack 21 and mounting the detector assembly 4 on the second rack 22, the first radiation source assembly 3 and the detector assembly 4 are arranged separately, which is not easy to block the operation of the transfer vehicle 6 in the goods handling area. Moreover, when the goods inspection system part scans the goods, it is not necessary to fold the radiation scanning device, which is beneficial to reducing the workload of personnel.

[0064] Reference Figure 3 In some embodiments, an inspection channel is formed between the first radiation source assembly 3 and the detector assembly 4, and the inspection channel can accommodate a plurality of lanes for the transfer vehicle 6 to run. The plurality of lanes refers to at least two lanes, and the plurality of lanes are arranged along a second direction Y perpendicular to the extension direction of the lanes, so that a plurality of transfer vehicles 6 loaded with goods 5 run along the lanes respectively to realize the transfer, wherein each lane can be parallel or substantially parallel to the first track 11 and the second track 12. Here, the second direction Y refers to Figure 3 the direction of the arrow and the opposite direction. The first radiation source assembly 3 and the detector assembly 4 are configured to scan the transfer vehicles 6 running on at least part of the plurality of lanes, that is, at least two transfer vehicles 6 have at least part of the goods 5 loaded thereon overlapping on the scanning surface when passing through the inspection channel. The first radiation source assembly 3 and the detector assembly 4 can also scan all the transfer vehicles 6 passing through the inspection channel. Compared with scanning each transfer vehicle, this is beneficial to improving the scanning efficiency. In other embodiments, each transfer vehicle can also be scanned.

[0065] In some embodiments, the distance between the first ray source assembly 3 and the detector assembly 4 along the second direction Y can be adjusted. For example, the first ray source assembly 3 is mounted on the first platform of the first rack 21, and the detector assembly 4 is mounted on the second platform of the second rack 21, and the first platform and / or the second platform can move along the second direction Y. The fan beam angle of the first ray source assembly 3 can also be adjusted. In this way, the distance between the first ray source assembly 3 and the detector assembly 4 and the fan beam angle of the first ray source assembly 3 can be adjusted according to the specific position of the transfer vehicle 6 on the multiple lanes and the number of transfer vehicles 6 expected to be scanned simultaneously, thereby ensuring the scanning range.

[0066] In some embodiments, the radiation scanning device can also scan transfer vehicles used to lift cargo on other quayside cranes. For example, in a scenario where multiple lanes include a first lane and a second lane, the first lane can be the path for transfer vehicles 6 lifted by quayside crane 100, while the second lane can be the path for transfer vehicles lifted by other quayside cranes (different from quayside crane 100). In this way, simply installing a radiation scanning device on the quayside crane 100 can scan cargo lifted by at least two quayside cranes. Transfer vehicles in the two lanes can travel in the same or different directions and can pass through the inspection channel simultaneously or sequentially.

[0067] Figure 4 yes Figure 1 A partial enlarged view of the middle area I, Figure 5 yes Figure 1 A partially enlarged view of a modified example of region I.

[0068] refer to Figure 4 and Figure 5 In some embodiments, the detector assembly 4 includes a detector 41 and an arm 42. The detector 41 is mounted on the arm 42. For example, the detector 41 may be fixedly connected to the arm 42. The arm 42 may be a vertical arm, which helps reduce the width of the occupied lane or the width of the unoccupied lane, thereby reducing the possibility of scratches or collisions with the transfer vehicle 6. The arm 42 may be an L-shaped arm, which can reduce the overall height of the arm 42 and facilitate inspection and maintenance.

[0069] refer to Figure 6 and Figure 7 In some embodiments, the first radiation source assembly 3 can be mounted on the first vertical beam 211, and the detector assembly 4 can be correspondingly mounted on the third vertical beam 221 to form an inspection channel. This mounting method also provides a more stable mounting of the first radiation source assembly 3 and the first vertical beam 211. Similarly, the first radiation source assembly 3 can also be mounted on the second vertical beam 212, and the detector assembly 4 can be correspondingly mounted on the fourth vertical beam 222.

[0070] Figure 8 is a side structural schematic diagram of another embodiment of the cargo inspection system according to the present disclosure. Referring to Figure 8 In some embodiments, the radiation scanning device further comprises a second radiation source assembly 3' and a second detector assembly 4', one of which is installed on the second vertical beam 212 and the other is installed on the fourth vertical beam 222, in the case that the first radiation source assembly 3 is installed on the first vertical beam 211 and the detector assembly 4 is installed on the third vertical beam 221. Since the first side S1 and the second side S2 of the shore crane 100 both allow the transfer vehicle 6 to pass through, such arrangement enables the scanning inspection by the radiation scanning device regardless of which side the transfer vehicle 6 drives away from the cargo handling area.

[0071] The second radiation source assembly 3' can be installed on the second vertical beam 212 and the second detector assembly 4' can be installed on the fourth vertical beam 222. In this way, the first radiation source assembly 3 and the second radiation source assembly 3' are located on the same side of the lane, which is conducive to the centralized arrangement of protective measures (such as shielding walls or warning areas), reduces the radiation risk to personnel, and makes power supply, wiring and equipment maintenance more convenient.

[0072] The second radiation source assembly 3' can also be installed on the fourth vertical beam 222 and the detector assembly 4' can be installed on the second vertical beam 212. The advantage of such arrangement is that one radiation source assembly and one detector assembly are installed on the first rack 21 and the second rack 22 respectively, which is conducive to making the force of the shore crane 100 more balanced and facilitating the installation of counterweights. In addition, when a transfer vehicle of another shore crane carrying goods passes through the inspection channel of the shore crane 100, the goods carried by the transfer vehicle can be scanned and inspected from both sides to obtain two side-view scanning images.

[0073] Similarly, in some embodiments, the first radiation source assembly 3 can be installed on the second vertical beam 212 and the first detector assembly 4 can be installed on the fourth vertical beam 222, one of the second radiation source assembly 3' and the second detector assembly 4' can be installed on the first vertical beam 211 and the other can be installed on the third vertical beam 221.

[0074] Figure 9 is a side structural schematic diagram of another embodiment of the cargo inspection system according to the present disclosure. Referring to

[0075] Referring to Figure 9 In some embodiments, the first rack 21 comprises a first cross beam 213 and the second rack 22 comprises a second cross beam 223, the first radiation source assembly 3 is installed on the first cross beam 213 and the first detector assembly 4 is installed on the second cross beam 223, for example, the first radiation source assembly 3 and the first detector assembly 4 can be suspended on the cross beams, which is conducive to making the installation more convenient.

[0076] Reference Figure 3 In some embodiments, the cargo inspection system further comprises a position sensor 7, which can be arranged on the first frame 21. The position sensor 7 is configured to send a position signal when detecting that the trolley 6 reaches a preset position. The preset position can be the starting position of the inspection channel, or can have a first preset distance from the starting position of the inspection channel, for example, can be the position where the cargo 5 is unloaded when the trolley 6 stops. The cargo inspection system further comprises a controller 8, which is configured to start the scanning process of the radiation scanning device after receiving the position signal. In this way, the cargo inspection system can only be started when the trolley 6 is passing through or about to pass through the inspection channel, which can save energy and reduce the risk of radiation affecting personnel, and is conducive to improving the consistency of radiation images. The scanning process includes that the first radiation source assembly 3 emits pulsed radiation to form a fan-shaped scanning surface, the scanning surface passes through the cargo 5 under inspection, and the first detector assembly 4 receives the attenuated radiation and converts it into an electrical signal.

[0077] In some embodiments, the cargo inspection system further comprises a state sensor, which can sense whether the trolley 6 needs to be inspected. When the trolley 6 does not need to be inspected, the radiation scanning device does not perform any operation. The case where the trolley 6 does not need to be inspected can be, for example, that the trolley 6 has already been inspected. The trolley 6 can be in communication connection with the state sensor, so that the state sensor can sense whether it needs to be inspected. The state sensor can be arranged on the first frame 21, for example.

[0078] In some embodiments, the cargo inspection system further comprises a start sensor, which can be used to sense whether the trolley 6 is started and to sense the running speed of the trolley 6. Here, the start sensor can be a speed sensor, for example, and can be arranged on the first vertical beam 211. When it is sensed that the trolley 6 is started, the radiation scanning device enters a preheating mode, and the beam frequency of the first radiation source assembly 3 and / or the second radiation source assembly 3' is determined according to the sensed speed of the trolley 6. In the preheating mode, the accelerating tube of the first radiation source assembly 3 and / or the second radiation source assembly 3' establishes an acceleration field through microwaves, but the electron source does not emit electrons before the controller 8 receives the position signal.

[0079] The radiation scanning device can perform normal scanning on the trolley 6 whose running speed is below a threshold value, and can obtain an undersampled image when scanning the trolley 6 whose running speed exceeds the threshold value. The radiation scanning device can mark the undersampled image, so as to facilitate subsequent interpolation and other processing of the undersampled image.

[0080] In some embodiments, the radiation scanning device stops running in the case that one transfer trolley 6 leaves the inspection channel and the start sensor does not sense the presence of the started transfer trolley 6. In the case that one transfer trolley 6 leaves the inspection channel and the start sensor senses the presence of the started transfer trolley 6, the radiation scanning device stops the scanning process and starts the preheating mode, and enables the radiation scanning device to start the scanning process after the controller 8 receives the in-place signal.

[0081] Based on the above-mentioned various cargo inspection systems, the present disclosure further provides a port comprising the aforementioned cargo inspection system.

[0082] In addition, the present disclosure further provides a cargo inspection method based on the aforementioned cargo inspection system, the steps of which can be executed by the controller local to the cargo inspection system or the control platform in communication with the controller local to the cargo inspection system, and the method comprises: performing scanning inspection on the transfer trolley 6 having the cargo 5 transferred between the cargo handling area and the yard outside the cargo handling area by the radiation scanning device.

[0083] In some embodiments, the cargo inspection method further comprises: performing loading and unloading of the cargo 5 on the transfer trolley 6 in the cargo handling area between the first gantry 21 and the second gantry 22 by the shore crane 100.

[0084] In some embodiments, the first radiation source assembly 3 and the first detector assembly 4 form an inspection channel therebetween, which can accommodate multiple lanes for the transfer trolley 6 to run; and the scanning inspection on the transfer trolley 6 having the cargo 5 transferred between the cargo handling area and the yard outside the cargo handling area by the radiation scanning device comprises: scanning inspection on the transfer trolley 6 running on at least part of the multiple lanes by the first radiation source assembly 3 and the first detector assembly 4.

[0085] In some embodiments, the radiation scanning device further comprises a second radiation source assembly 3' and a second detector assembly 4', and the second radiation source assembly 3' and the second detector assembly 4' also form an inspection channel therebetween, which can accommodate multiple lanes for the transfer trolley 6 to run. The scanning inspection on the transfer trolley 6 having the cargo 5 transferred between the cargo handling area and the yard outside the cargo handling area by the radiation scanning device further comprises: scanning inspection on the transfer trolley 6 running on at least part of the multiple lanes by the second radiation source assembly 3' and the second detector assembly 4'.

[0086] In some embodiments, the cargo inspection system further comprises an in-place sensor 7, and the cargo inspection method further comprises: sending an in-place signal by the in-place sensor in the case that the transfer trolley reaches a preset position; and receiving the in-place signal and enabling the radiation scanning device to start the scanning process according to the in-place signal.

[0087] The multiple embodiments in the specification are described in a progressive manner, the focus of each embodiment is different, and the same or similar parts between each embodiment can be referred to each other. For the method embodiment, since the whole and the steps involved have a corresponding relationship with the content in the system embodiment, the description is relatively simple, and the related parts can be referred to the part of the system embodiment.
