Description

Technical Field

[0001] This invention relates to the field of product operation and maintenance management technology, and in particular to a physical ID tag and its operation and maintenance management method. Background Technology

[0002] Traditional manual methods of warehousing and managing goods are gradually becoming inadequate for the pace of modern logistics, production, and warehousing. As a result, automated and electronic methods of goods management have emerged. In existing technologies, information is often loaded onto the goods to be managed in the form of electronic or graphic tags. The electronic system then identifies the tags to identify the goods and collects statistical information on the entry and exit of goods or their logistics routes.

[0003] For example, some existing technologies disclose an item management system, including: an identification group comprising multiple ring-shaped identification tags arranged around the outer wall of an item, wherein the characteristic information of the identification group corresponds to the item's identification information; and an identification device, which is at least used to obtain the item's identification information based on the characteristic information of the identification group; wherein the characteristic information of the identification group includes one or more combinations of the following characteristics: the number of ring-shaped identification tags, the color and / or size and / or shape of each ring-shaped identification tag, the arrangement order of the multiple ring-shaped identification tags, and the spacing between the multiple ring-shaped identification tags. This invention can achieve rapid and accurate identification of items, thereby facilitating automatic and standardized management of items.

[0004] However, the inventors of this invention have discovered that in practical applications, the above-mentioned identification method, which relies on a tag consisting of a series of multiple ring-shaped identification marks, often fails to identify the overall item identification information or results in inaccurate identification of the item identification information due to reasons such as contamination or damage to some areas of the tag or interference from reflections on the item surface. This has a negative impact on efficient, convenient, and accurate item operation and maintenance management. Summary of the Invention

[0005] To address the shortcomings of existing technologies, the present invention aims to provide a physical ID tag and its operation and maintenance management method.

[0006] To achieve the aforementioned objectives, the technical solution adopted by this invention includes:

[0007] In a first aspect, the present invention provides a physical ID tag, comprising multiple graphic code sub-units, each of which contains a corresponding sequence number information code and an item identity array information code.

[0008] The sequence number information code represents the arrangement order of the graphic code sub-units;

[0009] The arrangement of multiple item identity array information codes in the specified order represents the tag serial number of the physical ID tag, and the tag serial number can be used to indicate the identity information of the physical item to which the physical ID tag is attached.

[0010] Secondly, the present invention also provides a method for the operation and maintenance management of goods, comprising:

[0011] Provide items to be controlled, wherein multiple physical ID tags are affixed to the surface of the items to be controlled;

[0012] Image recognition is performed on the graphic code subunit in the physical ID tag to obtain multiple sequence number information codes and their corresponding item identity array information codes;

[0013] Based on the sequence number information code, the item identity array information code is arranged and combined to generate a tag serial number. The tag serial number can be used to indicate the identity information of the physical item to which the physical ID tag is attached.

[0014] Thirdly, the present invention also provides an item operation and maintenance management system for operating and managing items to be managed, wherein the items to be managed are provided with multiple physical ID tags as described above.

[0015] The item operation and maintenance management system includes:

[0016] The image recognition module is used to perform image recognition on the graphic code sub-unit in the physical ID tag to obtain multiple sequence number information codes and their corresponding item identity array information codes;

[0017] The identity information module is used to arrange and combine the item identity array information codes based on the order represented by the sequence number information code to generate a tag serial number. The tag serial number can be used to indicate the identity information of the physical item to which the physical ID tag is attached.

[0018] Fourthly, the present invention also provides a readable storage medium storing a computer program, which, when run, executes the steps of the above-described item operation and maintenance management method.

[0019] Based on the above technical solution, compared with the prior art, the beneficial effects of the present invention include at least the following:

[0020] The physical ID tag provided by this invention is equipped with a corresponding sequence number information code and an item identity array information code that can indicate the identity information of the item to be managed when combined in sequence. When multiple physical ID tags are set on the surface of the item to be managed, any digital identity array information with the same sequence number can be identified, and the information segment it represents can be identified, which improves the recognition rate of physical ID tags. Even if individual physical ID tags or graphic code sub-units are contaminated or damaged, or are obscured or affected by light reflection, the system can still identify the identity information of the item, which is conducive to efficient, convenient and accurate operation and maintenance management of items.

[0021] The above description is merely an overview of the technical solution of the present invention. In order to enable those skilled in the art to better understand the technical means of this application and to implement it in accordance with the contents of the specification, the preferred embodiments of the present invention are described below in conjunction with detailed drawings.

[0027] In view of the shortcomings of the prior art, the inventors of this invention, through long-term research and extensive practice, have proposed the technical solution of this invention. The following will further explain and illustrate this technical solution, its implementation process, and its principles.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0029] See Figure 1 and Figure 2The first aspect of the present invention provides a physical ID tag 1, which includes multiple graphic code sub-units 2, each of which contains a corresponding sequence number information code 3 and an item identity array information code 4.

[0030] The sequence number information code 3 represents the arrangement order of the graphic code subunit 2.

[0031] The multiple item identity array information codes 4, arranged in the specified order, represent the tag serial number of the physical ID tag 1. The tag serial number can be used to indicate the identity information of the physical item to which the physical ID tag 1 is attached.

[0032] Existing technologies offer several solutions for item maintenance and management using graphic tags. However, these solutions rely on single graphic tag information. When parts of the graphic tag are damaged, or interfered with by factors such as light obstruction or surface reflection, the graphic code within the tag becomes difficult to accurately identify. Using multiple duplicate tags is problematic because partial damage or interference can render the entire tag unrecognizable. Furthermore, selecting the correct identification information (e.g., the information represented by a completely undamaged tag) from multiple tags with different damage or interference locations reduces recognition efficiency and cannot guarantee sufficient accuracy.

[0033] In the technical solution provided in this embodiment of the invention, the provided physical ID tag 1 adopts a grouping and encoding method for identity information. That is, the tag serial number representing identity information is divided into multiple segments, each segment corresponding to the item identity array information code 4 in one of the graphic code sub-units 2. A sequence number information code 3 is set at a specific position in the graphic code sub-unit 2 to indicate the arrangement order of the graphic code sub-units 2, thereby indicating the sorting method corresponding to multiple item identity array information codes 4. In subsequent identification and maintenance management, even if multiple physical ID tags 1 set on the surface of the item to be identified are damaged or interfered with to varying degrees and in different positions, it is highly likely that the damage position of each physical ID tag 1 is not completely consistent. This reduces the probability that a segment of identity information cannot be identified in multiple physical ID tags 1 to an extremely low level. Thus, by indicating the sequence number information code 3, the probability of accurately combining the complete identity information represented by the item identity array information code 4 can be significantly improved.

[0034] In some implementations, the graphic code subunit 2 is provided with a marker number 5, which indicates the arrangement order of the graphic code subunit 2. Therefore, when the subsequent system detects damage to the physical ID tag 1, it can indicate generated interference prompts to the operator. These interference prompts may, for example, contain the sequence number of the unrecognizable item identification array information code 4. Based on this sequence number and the corresponding identification order of the ID tags, the location of light obstruction or reflective interference can be easily found, facilitating adjustments by the operator.

[0035] In some embodiments, the plurality of said graphic code sub-units 2 are arranged in an array; more preferably, as shown in the following embodiments. Figure 1-4 The linear array shown.

[0036] In some implementations, the sequence number information code 3 and / or the item identification array information code 4 may include, for example, any one or a combination of two or more of the following: QR code, barcode, and color ring code.

[0037] As a typical application example of the above technical solution, a matrix barcode composed of multiple graphic code sub-units 2 can be used to form an independent physical ID tag 1. Multiple independent physical ID tags 1, in a matrix form, are distributed on the surfaces of different items 7 to be controlled. The surfaces of the items can be flat or curved, improving the barcode recognition rate. Each graphic code sub-unit 2 barcode consists of two parts: serial number information and numerical information. The former represents the sequence number, and the latter represents the item information.

[0038] The physical ID tag 1, composed of multiple sub-units, expands the amount of information contained within the physical ID tag. After the serial number and numerical information of the graphic code sub-unit 2 are recognized, the numerical information represented by it can be correctly arranged and combined according to the sequence number to form the complete digital information of the physical ID tag 1.

[0039] In the above application, multiple graphic code sub-units 2 are distributed in a matrix on the planar or curved surface of the item to be identified. When the identity array information of any item with the same sequence number is identified, the part of the identity information it represents can be identified, which improves the recognition rate of the physical ID tag 1. Even if individual graphic code sub-units 2 in the physical ID tag 1 are contaminated, damaged, or interfered with, the system can still accurately, quickly, and efficiently identify the identity information of the item to be controlled 7.

[0040] See also Figures 2-4 The second aspect of this invention provides a method for the operation and maintenance management of items, comprising the following steps:

[0041] Provide an item 7 to be controlled, the surface of which is provided with a plurality of physical ID tags 1 provided in the above embodiments; the optimal choice is as follows Figure 2-4 The diagram shows a matrix-type label assembly 6.

[0042] Image recognition is performed on the graphic code subunit 2 in the physical ID tag 1 to obtain multiple sequence number information codes 3 and their corresponding item identity array information codes 4.

[0043] Based on the arrangement order represented by the sequence number information code 3, the item identity array information code 4 is arranged and combined to generate a tag serial number. The tag serial number can be used to indicate the identity information of the physical item to which the physical ID tag 1 is attached.

[0044] As a typical application example, the matrix-type tag assembly 6, composed of physical ID tags 1, is identified by the system, and its data is uploaded to form an inspection record, which is then processed for terminal data and used for operation and maintenance management.

[0045] In some implementations, multiple physical ID tags 1 are arranged in an array on the surface of the item to be controlled 7.

[0046] In some implementation schemes, the number of physical ID tags 1 on the surface of the item to be controlled 7 can be 4-8. In practical applications, a number of 4-8 is the optimal choice for achieving high recognition efficiency. If the number is lower than this, the probability of not recognizing all segments of identity information in the graphic code becomes relatively high. If the number is higher than this, it is easy to cause too much duplicate information in the recognized graphic code, which will cause interference and reduce recognition efficiency.

[0047] In some implementations, when the sequence number information code 3 and / or the item identity array information code 4 in any of the graphic code subunits 2 cannot be recognized by the image, a low confidence level is assigned to the sequence number information code 3 and the item identity array information code 4 in the other graphic code subunits 2 adjacent to that graphic code subunit 2; for multiple item identity array information codes 4 identified in the same order, the one with the highest confidence level is selected to generate the tag sequence number.

[0048] In practical observation, when there is some light obstruction or interference, or when there is dirt, the adjacent graphic codes are often affected to varying degrees. If the same confidence level is used to evaluate multiple item identity array information codes 4 with the same sequence number, it may lead to two parallel different recognition results, which in turn affects the accurate judgment of identity information.

[0049] And by adopting the above technical solutions, for example Figure 4Five physical ID tags 1 are arranged in a horizontal straight line. When either the sequence number information code 3 or the item identity array information code 4 in the first graphic code subunit 2 of the third physical ID tag 1 cannot be identified, the item identity array information code 4 in the adjacent second graphic code subunit 2 is given a halved confidence level, for example, the original confidence level is 1, and now the confidence level is 0.5. Similarly, when the adjacent third graphic code cannot be identified, its confidence level is further halved to 0.25. Ultimately, among the identified identity information fragments in the second graphic code subunit 2 of the five physical ID tags 1, the third identity information fragment is not used to piece together complete identity information because of its low confidence level. This avoids the influence of erroneous information caused by adjacent damaged or interfering areas. Of course, the specific form of assigning low confidence level can be, for example, halving or reducing by a certain percentage, etc.

[0050] In some implementations, when the sequence number information code 3 and / or the item identification array information code 4 in any of the graphic code subunits 2 cannot be recognized by the image, an interference prompt message is generated. This interference prompt message indicates that there is interference with the physical ID tag 1. By transmitting the interference prompt message to the operator, such as through text display or voice prompts, the operator can notice the interference with the graphic code, facilitating subsequent maintenance work such as cleaning, adjusting the position, and replacing the tag.

[0051] In some implementations, multiple physical ID tags 1 are identified sequentially. When the item identity array information code 4 corresponding to the same arrangement order is the same in two adjacent physical ID tags 1, the item identity array information code 4 corresponding to the same arrangement order in subsequent physical ID tags 1 is no longer identified. Thus, when two consecutive segments with the same arrangement order are identified and are the same, image recognition of the remaining segments corresponding to that order is no longer performed, reducing the amount of computation and thereby improving the efficiency of the recognition operation.

[0052] A third aspect of the present invention also provides an item operation and maintenance management system for performing operation and maintenance management on an item 7 to be managed, wherein the item 7 to be managed is provided with a plurality of physical ID tags 1 provided in any of the above embodiments.

[0053] The item operation and maintenance management system includes:

[0054] The image recognition module is used to perform image recognition on the graphic code subunit 2 in the physical ID tag 1 to obtain multiple sequence number information codes 3 and their corresponding item identity array information codes 4.

[0055] The identity information module is used to arrange and combine the item identity array information code 4 based on the arrangement order represented by the sequence number information code 3 to generate a tag serial number. The tag serial number can be used to indicate the identity information of the physical item to which the physical ID tag 1 is attached.

[0056] A fourth aspect of the present invention also provides a readable storage medium storing a computer program, which, when run, executes the steps of the item operation and maintenance management method in any of the above embodiments.

[0057] The computer-readable storage medium may include data signals propagated in baseband or as part of a carrier wave, carrying readable program code. Such propagated data signals may take various forms, including but not limited to electromagnetic signals, optical signals, or any suitable combination thereof. The readable storage medium may also be any readable medium capable of sending, propagating, or transmitting a program for use by or in conjunction with an instruction execution system, apparatus, or device. The program code contained on the readable storage medium may be transmitted using any suitable medium, including but not limited to wireless, wired, optical fiber, RF, or any suitable combination thereof. The program code for performing the operations of this invention may be written in any combination of one or more programming languages, including object-oriented programming languages ​​such as Java and C++, and conventional procedural programming languages ​​such as C or similar languages. The program code may be executed entirely on a user computing device, partially on an associated device, as a standalone software package, partially on a user computing device and partially on a remote computing device, or entirely on a remote computing device or server. In cases involving remote computing devices, the remote computing devices can be connected to user computing devices via any type of network, including local area networks (LANs) or wide area networks (WANs), or they can be connected to external computing devices (e.g., via the Internet using an Internet service provider).

[0058] Based on the above technical solutions and implementation cases, it can be clearly understood that the physical ID tag 1 provided in the embodiments of the present invention is provided with a corresponding sequence number information code 3 and an item identity array information code 4 that can indicate the identity information of the item to be managed 7 after being combined in order. When multiple physical ID tags 1 are set on the surface of the item to be managed 7, any digital identity array information with the same sequence number is identified, and the information segment it represents can be identified, which improves the recognition rate of the physical ID tag 1. Even if individual physical ID tags 1 or graphic code sub-units 2 are contaminated or damaged, or are obscured or affected by reflection, the system can still identify the identity information of the item, which is conducive to efficient, convenient and accurate execution of item operation and maintenance management.

[0059] It should be understood that the above embodiments are merely illustrative of the technical concept and features of the present invention, and are intended to enable those skilled in the art to understand the content of the present invention and implement it accordingly. They should not be construed as limiting the scope of protection of the present invention. All equivalent changes or modifications made in accordance with the spirit and essence of the present invention should be covered within the scope of protection of the present invention.
