[0002] Passenger packages need to be inspected in airports, high-speed railways, land ports, seaports and other scenarios. Currently, there is a tray return system for passenger security checks. After the passenger takes away the luggage, the tray recovery system needs to automatically recover the tray and reuse it in subsequent inspections. Therefore, a detection method and device that can accurately determine whether the tray is empty is crucial.

[0003] At present, the common recognition method is to identify the appearance images of the batch of pallets, and determine whether the pallets are empty by the comprehensive application of one or more methods of edge detection, deep learning recognition, and fuzzy matching. However, the above detection methods have strict requirements on the entire process:

[0032] Please also read Figures 1 to 4 The intelligent passenger security check empty tray detection system provided in the embodiment of the present application is now described. The intelligent passenger security check empty tray detection system comprises:

[0033] The upper bag conveyor belt 10 is provided with a first radio frequency reader 11, a first camera 12 and a tray 13. The tray 13 is provided with a radio frequency identification tag (not shown). The tray 13 is used to place items. The first radio frequency reader 11 is used to read the radio frequency identification tag, and the first camera 12 is used to photograph the tray 13.

[0034] The security inspection conveyor belt 20 is connected to the upper bag conveyor belt 10 and is provided with an article security inspection device 21, and the article security inspection device 21 is used to perform security inspection on the tray 13;

[0035] A sorting conveyor belt 30 is connected to the security inspection conveyor belt 20 and is provided with a sorting mechanism 31, wherein the sorting mechanism 31 is used to sort out the trays 13 with security inspection abnormalities;

[0036] The recycling conveyor belt 40 is connected to the sorting conveyor belt 30 and is provided with a second RF reader 41 and a second camera 42. The second RF reader 41 is used to read the RFID tag, and the second camera 42 is used to photograph the tray 13.

[0037] The backend management system is connected to the first radio frequency reader 11, the first camera 12, the second radio frequency reader 41 and the second camera 42 respectively, and is used to associate images of the same tray 13 according to radio frequency IDs.

[0038] It can be understood that, for example, in scenarios such as airports, high-speed railways, land ports, and seaports, passengers first carry items to the upper bag conveyor belt 10, and the passengers place the items in the tray 13. At this time, the first RFID reader 11 can read the RFID ID of the RFID tag, and the first camera 12 can take an image of the tray 13. Therefore, the background management system can associate the RFID ID obtained at the same time and the same location with the image of the tray 13.

[0039] After the tray 13 is transferred from the upper bag conveyor belt 10 to the security inspection conveyor belt 20 , the articles in the tray 13 are inspected by the article security inspection equipment 21 . The article security inspection equipment 21 may be an X-ray machine, an explosive detection equipment, a metal detection equipment, etc.

[0040] If an abnormality is found, the tray 13 containing the abnormal items can be sorted out by the sorting mechanism 31 in the sorting conveyor 30, and the items can be opened and inspected manually for further verification.

[0041] The trays 13 that have not been sorted by the sorting conveyor belt 30 are considered normal, and passengers can take their items away. Finally, the trays 13 will be transferred to the recycling conveyor belt 40 where the second RF reader 41 and the second camera 42 are installed. The second RF reader 41 reads the RF ID of the RFID tag again, and the second camera 42 takes a picture of the tray 13 again. The background management system can associate the images of the tray 13 taken twice before and after according to the RF ID. The inspection staff can compare and judge whether there are any missing items, new damage, etc. in the tray 13. Of course, the consistency of the images of the tray 13 taken twice can also be intelligently detected by machine vision to determine whether there are any missing items, new damage, etc. in the tray 13. If there are any missing items or new damage, the staff will take away the tray 13 for subsequent processing. If there is no problem with the tray 13, the tray 13 will be recycled.

[0042] The background management system can be a PC system, a host computer or a server, which is used to receive the detection data and analyze and process it. The first radio frequency reader 11 and the first camera 12 can be set in multiple groups, and multiple trays 13 can work at the same time.

[0043] Compared with the prior art, the intelligent passenger security empty tray detection system provided in the present application is characterized in that the upper bag conveyor belt 10 is provided with a first radio frequency reader 11 and a first camera 12, the recovery conveyor belt 40 is provided with a second radio frequency reader 41 and a second camera 42, and the tray 13 is provided with a radio frequency identification tag, and the images of the trays 13 with the same radio frequency ID are associated in the background management system, thereby realizing the detection of missing items, new damage and other problems of the trays 13 that are inconsistent, have advertisements and are worn in appearance, thereby improving the detection accuracy and the application scope of the tray 13, and reducing the appearance requirements of the tray 13.

[0044] In another embodiment of the present application, please refer to Figures 1 to 4 A first mounting bracket 14 is arranged above the upper package conveyor belt 10, the first camera 12 is arranged on the bottom surface of the first mounting bracket 14, the first radio frequency reader 11 is arranged below the upper package conveyor belt 10, and the radio frequency identification tag is arranged on the bottom surface of the tray 13.

[0045] It is understandable that the first mounting frame 14 can be a gantry structure. When the pallet 13 is placed on the upper bag conveyor belt 10, the RFID tag can better read the RFID ID of the first RFID reader 11, and the first camera 12 can capture the interior of the pallet 13 from a bird's-eye view.

[0046] For further information, please also refer to Figures 1 to 4 A face recognition terminal 15 is also provided on the first mounting frame 14. The face recognition terminal 15 is connected to the background management system and is used to obtain face information.

[0047] It is understandable that after the passenger places the luggage, the facial information can be obtained through the facial recognition terminal 15, and the background management system can also associate the facial information with the tray 13 so as to find the corresponding passenger when an abnormality is detected.

[0048] For further information, please also refer to Figures 1 to 4 The first mounting frame 14 is also provided with a certificate recognition terminal 16, which is connected to the background management system and is used to read certificate information.

[0049] It is understandable that after the passenger places the luggage, the passenger's ID information can be obtained through the ID recognition terminal 16, and the background management system can also associate the passenger's ID information with the tray 13 so as to find the corresponding passenger when an abnormality is detected.

[0050] For further information, please also refer to Figures 1 to 4 The recycling conveyor belt 40 is provided with a second mounting frame 43, and the second camera 42 is arranged on the second mounting frame 43, so that the viewing angle of the second camera 42 is set downward.

[0051] It can be understood that, based on the second mounting frame 43, the viewing angle of the second camera 42 can be set downward, and the second camera 42 can shoot the inside of the pallet 13 at a top-down angle. In this way, the viewing angles of the pallet 13 obtained by the first camera 12 and the second camera 42 are the same, which can improve the accuracy of comparison detection of the pallet 13.

[0052] For further information, please also refer to Figures 1 to 4A third radio frequency reader 22 is provided on the security inspection conveyor belt 20 . The third radio frequency reader 22 is connected to the background management system. The radio frequency ID of the tray 13 can be obtained based on the third radio frequency reader 22 .

[0053] It is understandable that when the article security inspection device 21 finds an abnormality, it can be associated with the corresponding passenger through the radio frequency ID.

[0054] In another embodiment of the present application, please refer to Figures 1 to 4 The intelligent passenger security check empty tray detection system includes an abnormal re-check conveyor belt 60, which is connected to the sorting conveyor belt 30, and the abnormal re-check conveyor belt 60 is used to cache the trays 13 sorted by the sorting mechanism 31.

[0055] It is understandable that if multiple abnormal trays 13 are detected continuously, the sorting mechanism 31 can cache the sorted trays 13 on the abnormal re-inspection conveyor belt 60 to prevent the trays 13 from piling up or being unprocessed in time and blocking the subsequent transmission of the trays 13. In another embodiment, the abnormal re-inspection conveyor belt 60 can also return the trays to the article security inspection device 21 for re-inspection.

[0056] In another embodiment of the present application, please refer to Figures 1 to 4 The intelligent passenger security empty tray detection system also includes an elevator 70 and a return conveyor belt (not shown). The elevator 70 is arranged at the end of the recovery conveyor belt 40. One end of the return conveyor belt is connected to the elevator 70, and the other end is connected to the upper bag conveyor belt 10.

[0057] It is understandable that the normal pallet 13 detected by the recovery conveyor belt 40 will enter the elevator 70, and will be lifted or lowered to the return conveyor belt by the elevator 70. The pallet 13 will return to the upper conveyor belt 10 through the return conveyor belt, thereby realizing the reuse of the pallet 13.

[0058] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
