[0033] Display: The display generally refers to a kind of flat panel device integrating display screen and computer functions. In express flow code identification, the display can also play an important role. The role of the display in express flow code identification includes but is not limited to: displaying flow code information: the display can be used to display the flow code information on the identified express package, so that the operator or staff can clearly view the information of the package. Interactive operation: the display has touch function, which can realize the interaction between the user and the system. The operator can input information and execute instructions through the display panel to facilitate the rapid processing of express flow code. Data management and processing: the display can be connected to the server or database to obtain and update express flow code data in real time, helping managers quickly understand and process the information of express packages.

In general, as a portable and interactive device, the display plays an important role in connecting information and personnel in the process of express flow code identification, improving the efficiency and accuracy of express identification and processing. The application of the display in the logistics industry also makes the management of express flow code more intelligent and convenient.

[0034] In the related art, as shown in FIG. 1, FIG. 1 is a product schematic diagram of a handheld code scanning terminal 1 in the related art. In the related art, the express sorting personnel holds the handheld code scanning terminal 1 by hand, uses the flow code scanning area 2 of the handheld code scanning terminal 1 to scan the express flow code of the express, obtains the express flow result of the express, and displays the express flow result on the express flow display screen 3 of the handheld code scanning terminal 1. After obtaining the express flow result, the express sorting personnel needs to hold the handheld code scanning terminal 1 with one hand and hold the express with the other hand to allocate the flow of the express, or put down the handheld code scanning terminal 1 and then allocate the flow of the express. The process is very cumbersome, and a lot of human resources are wasted, which reduces the efficiency of express flow code identification and the efficiency of express flow allocation. In addition, the handheld code scanning terminal 1 can only scan one express at a time, so the express sorting personnel needs to frequently use the handheld code scanning terminal 1 to scan and identify the express flow code of the express, which leads to low efficiency of express flow code identification.

[0035] The present application aims to at least solve one of the technical problems existing in the related art. To this end, the present application provides an express flow code identification device and an express flow code identification system. The camera assembly is used to scan and identify the express parcels on the express tray in the goods caching assembly, to obtain the placement position, shape and express flow code of the express rack. Compared with manually scanning each express parcel using a handheld scanning terminal, the scanning efficiency of the express parcels can be greatly improved, thereby improving the efficiency of express flow code identification. In addition, the industrial computer is used to find the flow direction of the express parcels matching the express flow code scanned by the camera assembly, to obtain the express flow result. Compared with the related art, the express flow result of all express parcels on the goods caching assembly can be found at the same time, thereby improving the express flow result finding efficiency and improving the express flow code identification efficiency. Finally, the display is used to display the placement position, shape and express flow result of all express parcels in the goods caching assembly, so that the express sorting personnel can clearly understand the express flow result of each express parcel in the goods caching assembly. Compared with the express sorting personnel assigning the flow direction to each express parcel according to the scanning result of the handheld scanning terminal, the express sorting personnel can simultaneously assign the flow direction to multiple express parcels with the same express flow result, thereby shortening the express parcel flow direction assignment time.

In addition, if there are multiple express items 600 on the express tray 210, the scanning camera 320 can simultaneously scan multiple express items 600 on the express tray 210. Compared with manually holding the scanning terminal to scan the express flow code of the express item one by one, the efficiency of express flow code scanning can be further improved. The industrial computer 400 is used to simultaneously find the express flow results matched by the express flow codes of the express items 600 on the express tray 210, which can improve the matching efficiency of the express flow codes of the express items 600, thereby improving the efficiency of express flow code identification. Finally, the display module 510 in the display 500 is used to display the placement position of the express item 600 on the express tray 210 and the shape of the express item 600, which avoids the express sorting personnel from taking the wrong express item 600, thereby improving the accuracy of express flow code identification.
