Abstract

This invention discloses an intelligent express sorting method based on OCR address recognition and dynamic grid matching. The sorting method is as follows: A scanner uses OCR technology to scan the waybill on the package to obtain information from it; the information from the waybill is matched with the address keyword list and segment code lookup table within the scanner. If a match is found, a corresponding three-segment code, grid information, and tracking number are generated and sent to the sorting machine; the package is placed at the loading area of ​​the sorting machine, and the sorting machine sorts the package into the corresponding grid according to the received signal, then sends the grid information to the express company. This invention, by having the scanner rescan abnormal packages that the sorting machine cannot sort and match them with the address keyword list and segment code lookup table to generate a corresponding three-segment code, grid information, and tracking number, sends these to the sorting machine, enabling the sorting machine to re-sort the abnormal packages, thereby improving sorting efficiency and reducing worker workload.

Description

Technical Field

[0001] This invention relates to the field of intelligent express sorting technology, specifically to an intelligent express sorting method and equipment based on OCR address recognition and dynamic grid matching. Background Technology

[0002] Express delivery, also known as courier or freight, refers to a new mode of transportation in which logistics companies use their own independent networks or joint ventures to deliver documents or packages entrusted by users quickly and safely from the sender to the recipient. In order to improve the speed of express delivery sorting, sorting machines are used to replace manual sorting. However, after the initial sorting by the sorting machine, packages with unclear addresses need to be sorted to the exception area, such as newly built communities or other newly added address information, and then sorted manually. Moreover, most of the sorted packages are directly sorted to the same community, and it is not possible to sort them by building. If the community is large, all the people in the community will gather in the same place to pick up their packages, which will reduce the efficiency of package pickup and increase the workload of manual labor. In addition to large communities, this situation also exists in places with a large number of people living on campus.

[0003] Furthermore, when a courier outlet needs to change its segment code, it must submit a segment code change request to the courier company via computer. After receiving the request, the courier company needs to change the original segment code for that area to an empty segment code (such as 000) before changing it to the new segment code. This process is relatively long, taking about one to two weeks. Before and initially after the change, the outlet's staff need to manually sort out these packages and then scan and deliver them using a scanner, which increases the time spent on package sorting and reduces the efficiency of code maintenance. To address this, an intelligent courier sorting method and equipment based on OCR address recognition and dynamic grid matching is proposed. Summary of the Invention

[0004] The purpose of this invention is to solve the above problems by proposing an intelligent express sorting method and equipment based on OCR address recognition and dynamic grid matching.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an intelligent express delivery sorting method based on OCR address recognition and dynamic grid matching, characterized in that: this sorting method is applied to parcels with unclear addresses, parcels with subdivided building locations, and parcels with changed segment codes, and the specific sorting method is as follows:

[0006] 1) After the packages are sorted by the sorting equipment for the first time, they are placed in a designated slot. Then, the packages in the same slot are sent to the identification device. The identification device scans the waybill on the package to obtain the segment code key information on the waybill.

[0007] 2) Match the segment code key information obtained from the waybill with the address keyword information and segment code lookup table stored in Kuaishou. If there is a matching address information and / or segment code, find the corresponding three-segment code, and find the grid information and salesperson information based on the three-segment code. Send the grid information, salesperson information and order number to the sorting machine.

[0008] 3) After the package is scanned by Kuaishou, it is placed on the sorting machine again. The sorting machine sorts the package according to the received information and places it into the corresponding slot. The sorting machine also uploads the new address of the package after the new segment code obtained from Kuaishou to the express company's system to store the new address.

[0009] 4) If the information on the waybill on the package does not match the address keyword list and segment code comparison table in Kuaishou, request the information from the courier company's headquarters. If the information from the courier company's headquarters still does not match, the package will be sorted to the abnormal area for manual processing. If the information from the courier company's headquarters does match, proceed to steps 2-3.

[0010] As a preferred method, Kuaishou identifies that the package has been scanned at least once according to steps 1-3, and then sorts the package in detail.

[0011] As a preferred method, before changing the segment code, the courier outlet needs to submit a segment code change request to the courier company's system. The sorting machine places the packages whose segment codes need to be changed into the same slot. The scanner identifies and scans the packages with changed segment codes and sorts them into the new slot. It then sends the new slot information and the courier's information to the sorting machine. The sorting machine sorts the packages with changed segment codes again based on the received information. At the same time, the sorting machine feeds back the new slot information and the courier's information to the courier company. The courier company then maintains the code so that all subsequent packages in that area are sorted into that slot.

[0012] Preferably, the identification device is an OCR express waybill scanning device.

[0013] This equipment operates based on an intelligent express sorting method that combines OCR address recognition and dynamic grid matching.

[0014] The beneficial effects of this invention are as follows: by scanning abnormal packages that the sorting machine cannot sort, and matching them with the address keyword list and segment code comparison table, the corresponding three-segment code information is found. Based on the three-segment code, the sorting compartment information and the courier delivery information are found. The sorting compartment information, the courier delivery information and the tracking number are sent to the sorting machine, so that the sorting machine can sort the abnormal packages again, thereby improving sorting efficiency and reducing the labor intensity of workers.

[0015] By recognizing that the packages in the same sorting area are scanned again by Kuaishou, the corresponding station segment code is obtained. The sorting machine then further sorts the packages according to the station segment code, making the sorting more detailed, thereby improving the sorting accuracy and the efficiency of picking up the packages.

[0016] By scanning packages that require segment code changes using Kuaishou, the packages are assigned to new sorting slots. The new slot information and the courier's information are then sent to the sorting machine, which continues sorting the packages. This reduces the time required for segment code changes and lowers the workload for workers. Attached Figure Description

[0017] Figure 1 This is a logic diagram of the present invention for sorting packages with unclear addresses.

[0018] Figure 2 This is a logic diagram of the detailed building sorting of packages according to the present invention.

[0019] Figure 3 This is a logic diagram of how the segment code of the package is changed according to the present invention. Detailed Implementation

[0020] Below we combine Figures 1-3 The present invention provides a further description of the intelligent express sorting method and equipment based on OCR address recognition and dynamic grid matching.

[0021] In this invention, the OCR express waybill scanning device first sets a large amount of detailed package address information for the corresponding area, the station segment code of the package after building subdivision, and the segment code information before and after the network point modifies itself. In addition, the segment code mentioned below is the third segment code in the three-segment code.

[0022] Example 1: Sorting packages with unclear addresses:

[0023] 1) If the address on the package is a new residential area or a new specific address A, and the address of the courier headquarters does not include the name of the new address A, then the package will be judged as an unidentified package after being sorted by the sorting machine. After the first sorting, it will be sorted to the abnormal area or a designated compartment.

[0024] 2) Packages with unclear addresses that have been sorted to the abnormal area or a specific compartment are sent to the OCR express waybill scanning device by manual or automatic conveying equipment. The OCR express waybill scanning device scans the waybill on the package to obtain key address information on the waybill, such as the name of the community and building number, the name of the village and the nameplate number, etc.

[0025] The information obtained from the waybill is matched with the address keyword list and segment code lookup table in the OCR waybill scanning device. If a match is found, the corresponding three-segment code is located, and the sorting station information and delivery personnel information are found based on the three-segment code. The sorting station information, delivery personnel information, and tracking number are then sent to the sorting machine. For example, after the OCR waybill scanning device obtains information A, it is matched with the address keyword list and segment code lookup table. During the matching, the specific road name and house number of address B, which is geographically close to A, can be compared with the road name and house number of A to form the three-segment code of A. Based on the three-segment code, the package should be placed in the corresponding sorting station (e.g., sorting station 1), and the sorting station information, delivery personnel information, and tracking number are sent to the sorting machine through the OCR waybill scanning device.

[0026] 3) Place the aforementioned express parcels back onto the sorting machine. The sorting machine, based on the received information, scans the parcel's waybill information again using its scanning device and sorts the parcels into the corresponding compartments. The sorting machine also uploads the newly obtained address information from the OCR waybill scanning device to the courier company's system, storing the new address and applying it to parcels with address A later to generate a third-segment code. This facilitates the sorting machine's ability to directly sort parcels according to the corresponding compartment information after recognizing the key address information, thus improving sorting efficiency.

[0027] 4) If the information on the waybill on the package does not match the address keyword list and segment code comparison table in the OCR express waybill scanning device, request the information from the express company headquarters. If the information from the express company headquarters still does not match the data, the package will be sorted to the abnormal area for manual processing. If the information from the express company headquarters does match the data, proceed to steps 2-3.

[0028] Example 2: Sorting packages by building:

[0029] 1) The sorting machine sorts packages from the same community or campus into the same compartment. Then, the packages in the compartment are sent to the OCR express waybill scanning device by manual or automatic conveying equipment to scan the waybill on the package and obtain the building number information on the waybill.

[0030] 2) Match the address information obtained from the waybill with the address keyword list and segment code comparison table in the OCR express waybill scanning device. For example, divide multiple building numbers in the community into the same salesperson information and grid information. After the matching is completed, send the salesperson information, grid information and order number to the sorting machine.

[0031] 3) Place the package back on the sorting machine, which sorts the package into the corresponding slot according to the detailed information received. This allows for the division of pick-up points for different buildings in the same community, making it convenient for residents of different buildings to pick up their packages nearby, reducing the concentration of pick-up points, thereby improving sorting accuracy and pick-up efficiency.

[0032] Specifically, the sorting machine sorts all the packages in the same community into compartment 1, and then uses an OCR express waybill scanning device to scan the packages in compartment 1 to obtain the building number of the package.

[0033] Then, the OCR express waybill scanning device matches the number of buildings the package belongs to and determines which slot the package should be placed in (e.g., buildings 1 to 5 in the community are matched to slot 1, and buildings 6 to 10 are matched to slot 2). The OCR express waybill scanning device scans and sends the slot information to the sorting machine, and then the package is placed on the sorting machine. When the sorting machine recognizes the building number, it places the package in the corresponding slot according to the numerical information of the building number. The sorting machine uploads the divided slot information to the express company's system for storage and uses it to generate the third segment code of the community station for the packages in the community later. This makes it easier for the sorting machine to directly sort according to the corresponding slot information after recognizing the corresponding building number, thus improving sorting efficiency.

[0034] Example 3: Changing the segment code of the package:

[0035] 1) First, the courier outlet submits a segment code change request to the courier company. The courier company then sends information about the packages whose segment codes need to be changed to the sorting machine. Based on this information, the sorting machine places the packages whose segment codes need to be changed into the same slot.

[0036] 2) Use an OCR express waybill scanning device to scan the waybill on the package that needs to have its segment code changed, and obtain the key address information and segment code information on the waybill;

[0037] 3) Match the key address information and segment code information obtained from the waybill with the updated address keyword list and segment code comparison table in the OCR waybill scanning device. After matching, find the updated three-segment code, find the compartment information and courier information based on the three-segment code, and then send the compartment information, courier information, and tracking number to the sorting machine and upload it to the system.

[0038] 3) Place the package back on the sorting machine's loading area. The sorting machine will then sort the package with the changed segment code again based on the received information, placing it into the corresponding slot. At the same time, the sorting machine will send the new slot information and the courier's information back to the courier company. The courier company will then maintain the new segment code, ensuring that all subsequent packages in that area are sorted into that slot. This way, when the sorting machine scans the key address information for that area later, it can directly sort the package into the changed slot without requiring manual scanning and delivery.

[0039] Specifically, if a delivery point wants to change the segment code of packages with segment codes 091, 092, and 093 to segment code 090, the delivery point submits a segment code change request to the courier company's system. The courier company sends the information of the packages whose segment codes need to be changed to the sorting machine. Based on the information, the sorting machine places the packages whose segment codes need to be changed to 091, 092, and 093 into the same slot. The OCR courier waybill scanning device identifies and scans these packages, matching the slot information with segment code 090 (e.g., slot 1). Then, it sends the slot information and segment code to the sorting machine, places the packages back on the sorting machine for sorting, and puts the packages with segment codes 091, 092, and 093 into slot 1. The sorting machine uploads the slot information and segment code to the courier company's system, where the courier company maintains the code. Subsequently, packages with segment codes 091, 092, and 093 will be directly placed into slot 1 with segment code 090.

[0040] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the scope of protection of the present invention.
