Description

Technical Field

[0002] At present, the automated sorting and processing technology of parcels has become a very important link in modern parcel processing centers. With the exponential growth of the number of parcels, the sorting and security inspection speed of parcels directly affects the efficiency of the parcel processing center. Especially for parcel processing centers involving import and export trade, during the manual sorting method of traditional parcels, when unloading the vehicle, manual workers need to place the parcels in an orderly manner, and security inspection personnel check for suspicious parcels by observing the display screen. The above methods are extremely inefficient and have a high error rate. On the other hand, the efficiency of parcel processing centers involving import and export trade is relatively low during the parcel sorting process. Especially when the number of parcels is too large, parcels are prone to be confused during the security inspection and sorting process, and often need to be processed a second time, which in turn leads to problems such as increased labor costs and low parcel inspection efficiency in the parcel processing center. Therefore, we propose a security inspection and sorting system, a security inspection and sorting method, an electronic device, and a storage medium. Summary of the Invention

[0022] The technical solutions in the embodiments of the present invention will be described below with reference to the accompanying drawings in the embodiments of the present invention.

[0023] It should be noted that: similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. At the same time, in the description of the present invention, terms such as "first" and "second" are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0024] As Figure 1 shown, the technical solution of the first aspect of the present invention provides a security inspection and sorting system, including: a server, the server is configured with a database and an identification unit, the database is used to store package barcodes, and the identification unit is used to query the database according to the identification result to determine the package type, where the package type specifically includes: a rejected identification package, which is a package with an unidentifiable barcode on the package; a suspicious package, which is a package containing contraband such as guns, knives, flammable and explosive substances, etc.

[0025] The first sorting module includes a truck unloading telescopic machine, a first alignment mechanism, a first barcode scanning device, an X-ray security inspection machine, and a first swing wheel sorting mechanism connected in sequence; wherein the truck unloading telescopic machine is used to transfer the packages in the transport vehicle to the first alignment mechanism one by one; wherein the X-ray security inspection machine uses a cross-belt medium-high-speed security inspection machine with X-ray scanning and identification functions and capable of detecting suspicious items in the prior art. Compared with the conventional security inspection machine in the existing security inspection system, by increasing the package transmission speed, the effect of improving the security inspection efficiency is achieved;

[0026] The second sorting module includes a transmission line, the input end of which is connected to the X-ray security inspection machine, and the output end is connected to a second alignment mechanism and a second barcode scanning device in sequence; the output end of the second barcode scanning device is respectively connected to a second swing wheel sorting mechanism and a third swing wheel sorting mechanism; the output end of the second swing wheel sorting mechanism is also provided with a return device and a code supplement device; the return device is used to return the suspicious packages that have been manually inspected and found to be correct to the second barcode scanning device; the code supplement device is used to supplement the code of the rejected identification packages and then return them to the second barcode scanning device;

[0027] The inspection unit is installed in the X-ray security inspection machine and communicates with the server, and is used to perform image recognition processing on the packages and obtain the recognition result; for example, if the inspection unit detects suspicious items in the package, it will upload the barcode corresponding to the package to the server, and the identification unit will judge the package type.

[0028] For the convenience of subsequent processing of packages and saving floor space, in this embodiment, the transmission lines between the devices in the first sorting module and the second sorting module are preferably circular transmission lines; among them, multiple swing wheel sorting mechanisms all adopt the existing swing wheel sorting mechanism composed of two outlets, a control cabinet, an inlet and outlet package monitoring device, a servo steering mechanism, and a conveying mechanism. Its main function is to sort the corresponding packages into the matching chutes through the identification information conveyed by the barcode scanning device and the security inspection machine. Its specific structure and working principle can refer to the invention patent with the publication number CN115027873A, a smart express loading, unloading and sorting system, unloading sorting and sorting loading method, which will not be elaborated here; among them, the supplementary code device is preferably a six-sided barcode scanning device or a five-sided barcode scanning device. Using a six-sided barcode scanning device can scan all sides of the package, and using a five-sided barcode scanning device can scan all sides of the package except the bottom surface. The specific barcode scanning method can be selected according to actual needs to meet the actual barcode scanning requirements; among them, the server is preferably a cloud server. In actual use, the cloud server can be accessed through an external terminal. The server can also be configured to track the position of packages in the system, which will not be elaborated here;

[0029] Compared with the prior art, the security inspection and sorting system provided by this embodiment can identify the barcodes and suspicious items of packages simultaneously through the cooperation of multiple swing wheel sorting mechanisms, multiple barcode scanning devices, and security inspection machines, and obtain the package identification results; based on the package identification results, the packages with problems are conveyed to the corresponding processing modules. The entire system does not require manual assistance except for the inspection of suspicious packages, reducing labor costs and improving the efficiency of package security inspection and sorting at the same time.

[0030] For example, also as Figure 1 shown, the system further includes:

[0031] A sub-line, whose input end is connected to the first swing wheel sorting mechanism and the third swing wheel sorting mechanism, and is used to subdivide the categories of packages;

[0032] A sub-swing wheel, whose input end is connected to the sub-line, and is used to control the packages to fall into the grid and be loaded onto the vehicle.

[0033] For example, as Figure 2As shown, both the first alignment mechanism and the second alignment mechanism include: a middle section 100 for wrapping and transporting in the middle; a single-piece separation section 200, the input end of which is connected to the middle section 100 for forming a single-piece flow of tightly adjacent and parallel packages; a divergence section 300, the input end of which is connected to the single-piece separation section 200 for separating the tightly adjacent and parallel packages in terms of width; a visual monitoring module 400 installed above the single-piece separation section 200 for identifying the number and position information of the packages on the single-piece separation section 200 and adjusting the conveying speed of the packages in the divergence section 300 according to the above information; when the packages in the middle section 100 enter the single-piece separation section 200, the visual monitoring module 400 automatically identifies and separates the packages on the single-piece separation section 200 based on the existing visual recognition algorithm to achieve the effect of single-package conveying, thereby improving the efficiency and accuracy of package sorting.

[0034] The following provides a simple example of the transmission line in the security inspection and sorting system of the present invention. Please refer to Figure 3 As shown, it includes an alignment mechanism 500, a distance pulling device 510, a high-speed transmission device 520, a barcode scanning device 530, a DWS system 540, an X-ray security inspection machine 550, and a sorting unit 560 that are connected in sequence from left to right. Among them, the DWS system 540 can adopt a data information acquisition system in the prior art that can at least achieve functions such as barcode recognition, volume measurement, and weighing of packages. The packages identified by the DWS system are transmitted to the subsequent assembly line through the sorting unit 560. Among them, the purpose of setting the high-speed transmission device 520 is to cooperate with the distance pulling device 510. By increasing the package transmission speed and controlling the distance between packages, the problem that packages are easily blocked on the transmission line is effectively avoided, and the subsequent security inspection efficiency is improved.

[0035] As Figure 4 As shown, the second aspect of the technical solution of the present invention also provides a security inspection and sorting method applied to the security inspection and sorting system described in any one of the first aspect of the technical solutions of the present invention, including the following steps:

[0036] Step 1: The packages to be inspected are transmitted to the first alignment mechanism through the unloading telescopic machine and are conveyed to the first barcode scanning device one by one.

[0037] Step 2: The packages to be inspected are identified by the first barcode scanning device. The packages with failed barcode scanning are regarded as rejected packages. The first barcode scanning device adopts a six-sided barcode scanner.

[0038] Step 3: The image information of the packages to be inspected is obtained by the X-ray security inspection machine, and the method of image analysis and comparison is used to identify dangerous objects. The packages that fail to pass the identification of the X-ray security inspection machine are regarded as suspicious packages.

[0039] Step 3 further includes: Parcels that fail to pass the security check by the security inspection machine are regarded as suspicious parcels, and the barcode information of the suspicious parcels is stored in the database.

[0040] Step 4: The unrecognized parcels and suspicious parcels are scanned a second time, and the qualified parcels are sorted and loaded onto the vehicle.

[0041] Among them, the unrecognized parcels and suspicious parcels in Step 4 are conveyed to the collection and transmission line together, and after the position of the parcels is adjusted by the second alignment mechanism, they are scanned a second time;

[0042] Among them, the second scan specifically includes:

[0043] Scanning the barcode through the second barcode scanning device and comparing it with the barcode information of the suspicious parcels in the database;

[0044] If the barcode of the parcel exists in the database, it is regarded as a suspicious parcel and subject to manual inspection; if the barcode of the parcel does not exist in the database, it is regarded as an unrecognized parcel and the supplementary code is transmitted back.

[0045] Among them, the supplementary code transmission specifically includes: supplementing the code of the unrecognized parcel through the supplementary code device, and after the code supplement is completed, it is conveyed to the second barcode scanning device through the transmission device for re-scanning until the barcode of the parcel is successfully scanned and then conveyed to the third pendulum sorting mechanism;

[0046] Among them, the manual inspection specifically includes: manually disassembling and inspecting the suspicious parcel by hand. If there are prohibited items in the parcel, the parcel is detained; if there is no abnormality in the parcel, it is transmitted back to the second barcode scanning device, and after subsequent processing, it is sorted and loaded onto the vehicle.

[0047] In summary, the security inspection and sorting method provided by the present disclosure stores and remembers the barcodes of suspicious parcels through the database, and through the barcode comparison after the second scan, automatically sorts out the suspicious prohibited parcels, ensuring that 100% of the parcels pass through the security inspection machine and the effectiveness of the barcodes on the parcels. In actual application, a large number of parcels can be centrally inspected, suspicious parcels can be automatically judged, and suspicious parcels can be automatically sorted, which not only meets the management objectives of the parcels but also achieves the effect of replacing manual inspection and improving efficiency.
