Description

Technical Field

[0001] The present invention relates to the technical field of intelligent express sorting, and specifically to an intelligent express sorting method and device based on OCR address recognition and dynamic grid matching. Background Art

[0002] Express delivery, also known as courier or express transportation, refers to a new mode of transportation in which logistics companies use their own independent networks or joint ventures to quickly and safely deliver documents or parcels entrusted by users from senders to recipients. In order to improve the speed of express delivery sorting, sorting machines are used instead of manual sorting in existing technologies. However, after the initial sorting, the sorting machine needs to sort parcels with unclear addresses to abnormal ports, such as newly built residential areas or other newly added address information, and then manually sort them. Moreover, most of the sorted parcels are directly sorted to the same residential area and cannot be sorted by detailed buildings. If the residential area is large, all the parcel collectors in the residential area will gather at the same place to pick up the parcels, which reduces the efficiency of picking up the parcels and increases the workload of manual workers. In addition to large residential areas, this situation also exists in places with a large population, such as campuses. In addition, when express delivery outlets need to change their segment codes, they must submit a segment code change request to the express delivery company on a computer. After receiving the request, the express delivery company must change the original segment code in the area to a blank segment code (such as 000) and then change it to the changed segment code. This process is relatively long and takes about one to two weeks. Before and after the change is completed, express parcels at the outlets need to be manually sorted out and then scanned and dispatched using a scanner, which increases express sorting time and reduces the efficiency of code maintenance. To this end, an intelligent express sorting method and equipment based on OCR address recognition and dynamic grid matching is proposed. Summary of the Invention

[0003] The purpose of the present invention is to solve the above problems and to propose an intelligent express sorting method and equipment based on OCR address recognition and dynamic grid matching.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an intelligent express sorting method based on OCR address recognition and dynamic grid matching, characterized in that the sorting method is applicable to packages with unclear addresses, parcel building subdivisions, and segment code changes. The specific sorting method is as follows: 1) After the parcels have been sorted by the sorting equipment for the first time, they are placed in a designated slot. Then, the parcels in the same slot are sent to the identification device, which scans the parcel label to obtain the key information of the segment code on the parcel label. 2) Match the segment code key information obtained on the waybill with the address keyword information and segment code comparison table stored in the identification tool. If there is a match in the address information and / or segment code, find the corresponding three-segment code, and find the slot information and salesperson information based on the three-segment code. Then send the slot information, salesperson information and order number to the sorting machine; 3) After the parcel has been scanned by the identification hand, it is placed on the sorting machine again. The sorting machine sorts the parcel and places it in the corresponding slot according to the information received. The sorting machine also uploads the new address of the slot where the parcel is placed after the new segment code obtained from the identification hand to the courier company system and stores it; 4) When the label information on the package does not match the address keyword list and segment code comparison table in the identification tool, request the express company headquarters for the slot information. If the slot information released by the express company headquarters still does not have matching information, the package will be sorted to the abnormal slot for manual processing. If the slot information released by the express company headquarters has matching information, proceed according to steps 2-3.

[0005] Preferably, the identification tool scans the package at least once according to the method of steps 1 to 3, and sorts the package into smaller categories.

[0006] As a preferred option, before the segment code is changed, the express delivery outlets need to submit a segment code change request to the express delivery company system. The sorting machine will drop the parcels that need to change the segment code to the same grid. The identification tool will identify and scan the parcels with the changed segment code and sort them into the new grid. The new grid information and the courier's information will be sent to the sorting machine. The sorting machine will sort the parcels with the changed segment code again according to the received information. At the same time, the sorting machine will feed back the new grid information and the courier's information to the express delivery company. The express delivery company will maintain the code so that all subsequent parcels in the area will be sorted into the grid.

[0007] Preferably, the identification tool is an OCR express delivery bill scanning device.

[0008] The device works based on the intelligent express sorting method of OCR address recognition and dynamic grid matching.

[0009] The beneficial effects of the present invention are as follows: by identifying the quick hand, the abnormal packages that the sorting machine cannot sort are scanned and matched with the address keyword list and the segment code comparison table to find the corresponding three-segment code information, and the slot information and courier delivery information are found according to the three-segment code, and the slot information, courier delivery information and order number are sent to the sorting machine, so that the sorting machine can sort the abnormal packages again, thereby improving the sorting efficiency and reducing the labor intensity of workers; By identifying the quick hand, the parcels in the same sorting area are scanned again to obtain the corresponding post station segment code. The sorting machine further refines the parcels according to the post station segment code, thereby improving the sorting accuracy and the efficiency of picking up the parcels. By identifying the quick hand, the parcels that need to change the segment code are scanned and sorted into the new slot. The new slot information and the courier's information are sent to the sorting machine, and the sorting machine continues to sort them, thereby reducing the time for segment code change and reducing the labor intensity of workers.

[0013] Next we combine Figure 1-Figure 3 The intelligent express sorting method and device based on OCR address recognition and dynamic grid matching described in the present invention are further explained.

[0014] In the OCR express delivery bill scanning device of the present invention, a large amount of relatively detailed package address information of the corresponding area, the post station segment code of the package after building segmentation, and the segment code information before and after the outlet's own modification are first set. In addition, the segment codes mentioned below are all the third segment codes in the three-segment codes.

[0015] Example 1: Sorting of packages with unclear addresses: 1) If the address on the package is a new residential complex or another specific new address A, and the address of the courier headquarters does not include the new address A, the package will be judged as an unclear address package after being sorted by the sorting machine. After the first sorting, it will be sorted to the abnormal port or a designated slot; 2) Parcels with unclear addresses that are sorted to an abnormal port or a designated slot are sent to an OCR express delivery bill scanning device through manual or automatic conveying equipment. The OCR express delivery bill scanning device scans the parcel delivery bill to obtain key address information on the parcel delivery bill, such as the community name and building number, village name and nameplate number, etc. The information obtained on the express delivery note is matched with the address keyword list and segment code comparison table in the OCR express delivery note scanning device. If there is matching information, the corresponding three-segment code is found, and the grid information and salesperson delivery information are found based on the three-segment code, and the grid information, salesperson delivery information and order number are sent to the sorting machine; for example, this includes scanning the information of A obtained by the OCR express delivery note scanning device and matching it with the address keyword list and segment code comparison table. When matching, the specific road name and house number of address B, which is geographically close to A, can be matched with the road name and house number of A to form the three-segment code where A is located. According to the three-segment code, the package should be delivered to the corresponding grid (for example, grid 1), and the grid information, salesperson delivery information and order number are sent to the sorting machine through the OCR express delivery note scanning device; 3) The above-mentioned express parcel is placed on the sorting machine again. The sorting machine scans the express parcel's waybill information again through the scanning device on the sorting machine according to the received information, and then sorts the express parcel into the corresponding slot. The sorting machine uploads the new address information obtained by the OCR express waybill scanning device to the courier company's system, stores the new address, and applies it to the parcel with address A in the future to generate the third segment code; so that the sorting machine can directly sort according to the corresponding slot information after identifying the corresponding address key information in the future, thereby improving the sorting efficiency; 4) When the label information on the package does not match the address keyword list and segment code comparison table in the OCR express label scanning device, request the express company headquarters for the slot information. If the slot information released by the express company headquarters still does not have matching data, the package will be sorted to the abnormal slot for manual processing. If the slot information released by the express company headquarters has matching data, it will be processed according to steps 2-3.

[0016] Example 2: Sorting of parcels by building: 1) The sorting machine sorts the parcels of the same community or campus into the same compartment, and then sends the parcels in the compartment to the OCR express delivery bill scanning device through manual or automatic conveying equipment to scan the parcel delivery bill and obtain the building number information on the express delivery bill; 2) Match the address information obtained on the express delivery bill with the address keyword list and segment code comparison table in the OCR express delivery bill scanning device. For example, multiple building numbers in a residential area are divided into the same salesperson information and slot information. After the matching is completed, the salesperson information, slot information and order number are sent to the sorting machine; 3) Place the parcel on the sorting machine again, and the sorting machine will sort the parcel into the corresponding compartment according to the detailed information of the parcel received. This can divide the pickup points of different building numbers in the same community, making it convenient for residents of different building numbers to pick up their parcels nearby, reducing the concentration of pickup, thereby improving sorting accuracy and also improving pickup efficiency.

[0017] Specifically, the sorting machine sorts all parcels from the same community into slot 1, and then uses the OCR express delivery bill scanning device to scan the parcels in slot 1. The OCR express delivery bill scanning device scans the parcels to obtain the building number. Then, the OCR express delivery bill scanning device matches the building the package belongs to and which grid the package of that building should fall into (for example, buildings 1 to 5 of the community are matched to grid 1, and buildings 6 to 10 are matched to grid 2). The OCR express delivery bill scanning device scans and sends the grid information to the sorting machine, and then places the package on the sorting machine. When the sorting machine identifies the building number, it will drop the package into the corresponding grid according to the digital information of the building number. The sorting machine uploads the divided grid information to the express company system for storage, and will be used to generate the third segment code of the community station for this community package in the future; this makes it easier for the sorting machine to identify the corresponding building number and directly sort according to the corresponding grid information, thereby improving the sorting efficiency.

[0018] Example 3: Changing the segment code of a package: 1) First, the express delivery outlet submits a code change request to the express delivery company. The express delivery company sends the information of the parcels that need code change to the sorting machine. The sorting machine will drop the parcels that need code change to the same slot according to the information. 2) Scan the parcel whose segment code needs to be changed using an OCR express delivery bill scanning device to obtain the key address information and segment code information on the parcel delivery bill; 3) Match the key address information and segment code information obtained from the express delivery bill with the address keyword list and segment code comparison table modified in advance in the OCR express delivery bill scanning device. After matching, find the changed three-segment code. Based on the three-segment code, find the slot information and courier information. Then send the slot information, courier information and order number to the sorting machine and upload them to the system. 3) Place the express at the loading area of the sorting machine again. The sorting machine will sort the parcels with the changed segment code again according to the received information and sort the parcels to the corresponding slots. At the same time, the sorting machine will feedback the new slot information and the courier's information to the courier company. The courier company will maintain the code so that all subsequent parcels in this area will be sorted to this slot. In this way, when the sorting machine scans the key address information of this area later, it can directly sort the parcel to the changed slot without the need for manual scanning and delivery.

[0019] Specifically, the outlet wants to change the parcels with segment codes 091, 092, and 093 to segment code 090. The express outlet submits a segment code change request to the express company system. The express company sends the information of the parcels that need to change the segment code to the sorting machine. The sorting machine drops the parcels that need to change the segment code to 091, 092, and 093 into the same grid according to the information. The OCR express delivery bill scanning device identifies and scans these parcels, matches the grid information with segment code 090 (for example, grid 1), and then sends the grid information and segment code to the sorting machine. The parcels are placed on the sorting machine again for sorting, and the parcels with segment codes 091, 092, and 093 are dropped into grid 1. The sorting machine grid information and segment code are uploaded to the express company system, and the express company maintains the code. Subsequently, parcels with segment codes 091, 092, and 093 are directly dropped into grid 1 with segment code 090.

[0020] The above embodiments are intended to illustrate the present invention, not to limit the present invention. Any solution that is a simple transformation of the present invention falls within the protection scope of the present invention.
