Detailed Description
The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.
The first embodiment is as follows:
in order to solve the problems that in the prior art, the fault tolerance of an identification tag is not high and the practical industrial application is not facilitated, the embodiment of the application provides the identification tag. The identification tag provided in the embodiment of the present application is described below with reference to the identification tags shown in fig. 1 to 8 (fig. 1 to 8 are schematic structural diagrams of several identification tags provided in the embodiment of the present application).
Referring to fig. 1 to 8, an identification tag 1 provided in an embodiment of the present application includes: a backplane 11 and a plurality of sets of coded bits 12. Wherein:
the plurality of groups of coded bits 12 include information code coded bits and error correction code coded bits, the information code coded bits and the error correction code coded bits are distributed on the bottom plate 11 according to coding rules of erasure codes to form erasure code coding patterns, and the coded bits 12 and regions of the bottom plate 11 except the coded bits 12 have different display forms.
The erasure correction code encoding pattern described in the embodiments of the present application refers to a pattern obtained according to an encoding rule of an existing erasure correction code. The distribution form of the information code coding bits and the error correcting code coding bits in the pattern is consistent with the coding rule of the existing erasure codes. In the embodiment of the present application, the erasure code coding pattern may adopt a coding pattern of an array erasure code (array code), a coding pattern of a reed-solomon erasure code (RS), a coding pattern of a Low Density Parity Check (LDPC) erasure code, and the like, which is not limited in the embodiment of the present application.
It should be further noted that, in the embodiment of the present application, the structure of the coded bit 12 may be, but is not limited to, at least one of the following:
the implementation structure is as follows: the base plate 11 may be provided with a plurality of protruding structures, and the encoding bits 12 are the protruding structures, as shown in fig. 1, 6, and 7.
And a second structure is realized: the bottom plate 11 may include a top plate 111 having a plurality of through holes and a substrate 112 disposed under the top plate 111. The coded bits 12 are through holes in the top plate 111, as shown in fig. 2, 4, and 5.
The third structure is realized: the bottom plate 11 may be provided with a plurality of slots, and the encoding bits 12 are slots on the bottom plate 11, as shown in fig. 3.
It will be appreciated that the structure of the coded bits 12 may also be a combination of the above structures, such as: the information code encoding bit is a convex structure, the error correction code encoding bit is a groove body, or the information code encoding bit is a through hole on the top plate 111, and the error correction code encoding bit is a convex structure on the top plate 111.
It should be noted that, in the embodiment of the present application, the coded bits 12 and the area of the bottom plate 11 except the coded bits 12 have different display forms, so that the erasure code coded pattern formed by the coded bits 12 has a certain contrast with the area of the bottom plate 11 except the coded bits 12, thereby being convenient for accurately identifying the erasure code coded pattern in the later identification process.
For example, the coded bits 12 may be different from the areas of the bottom plate 11 except the coded bits 12 in at least one of color, shape, height, etc. to achieve different display forms. For example, the color of the coded bit 12 is red, and the color of the region of the bottom plate 11 except the coded bit 12 is blue; for another example, the coded bits 12 are circular in shape, and the regions of the bottom plate 11 other than the coded bits 12 are rectangular in shape; for another example, the coded bits 12 have a height of 5cm, and the region of the substrate 11 other than the coded bits 12 has a height of 2cm, and so on.
It should be noted that, in the case that the coded bits 12 and the area of the bottom plate 11 except the coded bits 12 have different display forms, the information code coded bits and the error correction code coded bits may also have different display forms, such as at least one of color, shape, height, and the like. Of course, the information code encoding bits and the error correction code encoding bits may have the same display form, and are not limited in the embodiment of the present application.
In addition, the coded bits may have different display forms, such as different colors, shapes, heights, and the like. For example, the information code bit a is purple in color and square in shape, the error correction code bit B is cyan in color and triangle in shape, the information code bit C is yellow in color and circle in shape, the error correction code bit D is red in color and star in shape, and so on.
It should be noted that, as long as the coded bits 12 and the areas of the bottom plate 11 except the coded bits 12 have different display forms, whether the display forms between the coded bits 12 are the same or not is not limited in the embodiment of the present application.
It should be understood that in erasure codes, there are two types of codes, respectively a code corresponding to a value of 1 and a code corresponding to a value of 0. In order to be consistent with the encoding rule of the erasure code, in the embodiment of the present application, the encoding bits 12 should include a first encoding bit corresponding to a value 1 and a second encoding bit corresponding to a value 0, and the first encoding bit and the second encoding bit should adopt different display modes. For example, referring to fig. 8, the second coding bit corresponding to the value 0 is a star-shaped through hole on the top plate 111, and the first coding bit corresponding to the value 1 is a circular through hole on the top plate 111.
In addition, since the coded bit 12 in the present application has a different display form from the region of the bottom plate 11 except the coded bit 12, in the embodiment of the present application, the coded bit 12 may also only include the first coded bit corresponding to the value 1, or only include the second coded bit corresponding to the value 0. For example, as shown in fig. 1 to 7, only the first coded bit corresponding to the value 1 is included. At this time, there is no coded bit corresponding to the value 0, and the coded bits that should exist can be identified based on the coding rule of the erasure code during the identification, but the position where there is no coded bit actually carries information with the value 0.
In one possible implementation of the embodiment of the present application, the identification tag 1 may comprise only a backplane 11 and a plurality of sets of coded bits 12, such as shown in fig. 1.
It should be understood that the accuracy of the erasure code coding pattern acquisition will directly affect the accuracy of the later information acquisition. Therefore, in order to quickly and accurately locate the location area of the erasure coding pattern on the base plate 11, in another possible implementation manner of the embodiment of the present application, the identification tag 1 may further include a location bit 13. The positioning bits 13 are located on the bottom plate 11, and form a predetermined positioning pattern on the bottom plate 11, and the relative positions of the positioning pattern and the erasure code coding pattern on the bottom plate 11 are fixed. Thus, when the positioning pattern is detected in advance during label identification, the position of the erasure code coding pattern can be obtained according to the position of the detected positioning pattern and the fixed relative position information, so that the erasure code coding pattern can be quickly obtained.
It should be understood that the structure of the positioning bits 13 may be, but is not limited to, at least one of the following:
the implementation structure is as follows: the positioning portion 13 is a protruding structure disposed on the bottom plate 11, as shown in fig. 6 and 7.
And a second structure is realized: the bottom plate 11 may include a top plate 111 having a plurality of through holes and a base plate 112 disposed under the top plate 111, and the positioning locations 13 are through holes on the top plate 111, as shown in fig. 2, 4, 5, and 8.
The third structure is realized: the positioning portion 13 is a groove provided on the bottom plate 11, for example, as shown in fig. 3.
It should be understood that, when the positioning bits 13 are present in the identification tag 1, the structures of the positioning bits 13 and the encoding bits 12 can be implemented in any one or more of the manners described above. Such as: the coding bit 12 may be a groove on the bottom plate 11, and the positioning bit 13 is a protrusion on the bottom plate 11; alternatively, the encoding bit 12 is a through hole on the top plate 111, and the positioning bit 13 is a protruding structure on the top plate 111.
It should be noted that, in the second possible embodiment, the positioning locations 13 and the areas of the bottom plate 11 except the positioning locations 13 have different display forms. Thus, when the tag is identified, the position of the positioning pattern can be quickly obtained through the different display forms of the positioning bits 13 and the areas except the positioning bits 13 on the bottom plate 11, and further the position of the erasure code coding pattern can be quickly obtained.
Illustratively, the positioning locations 13 and the areas of the bottom plate 11 other than the positioning locations 13 may differ in at least one of, but not limited to, color, shape, height, etc. It should be understood that, besides making the colors, shapes, heights, etc. different, the positioning locations 13 and the areas of the bottom plate 11 other than the positioning locations 13 may also have different display forms in other ways, which is not limited in the embodiment of the present application.
Illustratively, the bottom plate 11 may include a top plate 111 having L-shaped through holes, and a base plate 112 disposed under the top plate 111, wherein the positioning bits 13 are L-shaped through holes on the top plate 111, and both ends of the L-shaped through holes are flush with the edge of the erasure coding pattern, and the coding bits 12 are circular through holes, for example, see the structure shown in fig. 2. Alternatively, the pattern of the positioning bits 13 may be a pattern surrounding three sides of the erasure code encoding pattern or a pattern surrounding four sides of the erasure code encoding pattern, as in the structures shown in fig. 4 to 5. Alternatively, the pattern of positioning bits 13 may be a pattern located at three or four corners of the erasure coding pattern, as shown in fig. 6 to 7.
It should also be noted that in the present embodiment, the melting point of the base plate 11 of the identification tag 1 may be higher than the maximum operating temperature of the article to be identified. For example, in a molten iron transportation scene, a bottom plate made of high-temperature resistant materials such as stainless steel and ceramics can be adopted.
In addition, the base plate 11 of the identification tag 1 may be made of a material that is corrosion resistant and/or not easily reflective, such as plated metal, steel with chromium or nickel added, etc.
It should be understood that the above materials are only materials that can be used in the embodiments of the present application, and do not represent that only the bottom plate made of the above materials can be used in the embodiments of the present application.
In summary, the identification tag 1 provided in the embodiment of the present application includes a bottom plate 11 and a plurality of sets of coded bits 12 located on the bottom plate 11. Each group of coded bits includes coded bits of information code and coded bits of error correction code, and erasure code coding patterns are formed on the bottom plate 11, and the coded bits 12 and the areas of the bottom plate 11 except the coded bits 12 have different display forms. In this way, when tag identification is performed, information carried by the erasure code coding pattern can be obtained by decoding the erasure code coding pattern in the identification tag 1. If the information on the information code coding bit on the identification tag 1 is damaged or the decoding is wrong, error correction can be performed according to the information of the error correction code coding bit, so that correct information can be obtained; if the information on the error correcting code coding bit on the identification tag 1 is damaged and the information code coding bit is not damaged, the information of the information code coding bit can still be normally decoded, so that the information carried by the erasure code coding pattern is obtained, the fault tolerance of the identification tag is improved, and the identification tag is beneficial to the application of the identification tag in the actual industry.
Example two:
on the basis of the first embodiment, the embodiment of the present application further provides an identification system, as shown in fig. 9, the identification system includes: the identification tag 1, the information acquisition device 2, and the resolver 3 according to any one of the configurations shown in the first embodiment. Wherein:
the identification tag 1 is arranged on an article to be identified.
When the article to be identified passes through the preset information acquisition area, the information acquisition device 2 acquires information of the identification tag 1 on the article to be identified, and sends the acquired information containing the erasure code coding pattern of the identification tag 1 to the analyzer 3.
The analyzer 3 is configured to decode the erasure code coded pattern to obtain information carried by the erasure code coded pattern.
If the positioning pattern exists in the identification tag 1, the parser 3 is further configured to identify the positioning pattern, determine an area where the erasure code coding pattern is located according to the positioning pattern, and further decode the erasure code coding pattern.
It should be further noted that, in the embodiment of the present application, the information acquisition device 2 may be a video camera, a still camera, a scanner, or the like. The analyzer 3 is a decoding device for realizing information encoding, and may be an electronic device such as a computer, a server, or a single chip microcomputer having image recognition and erasure code analysis capabilities.
It should be further noted that, in the embodiment of the present application, in order to facilitate information acquisition and post-maintenance of the identification tag 1 on the article to be identified, the identification tag 1 may be installed at a specific position of the article to be identified or at a position away from the ground by a specified height.
It is noted that the identification system can be applied to a scene requiring an identification process for an article. For example, the identification tag 1 provided by the embodiment of the application can be arranged on a hot metal ladle car in a molten iron transportation scene, the hot metal ladle car number is carried by using an erasure code coding pattern, and then the identification of the hot metal ladle car number is realized by using the information acquisition device 2 and the analyzer 3. For another example, the method can also be applied to a logistics transportation scene, the identification tag 1 provided by the embodiment of the application is arranged on the package, the package number of the package is carried by using the erasure code coding pattern, and the package number is identified by using the information acquisition device 2 and the analyzer 3.
To sum up, the identification system provided in the embodiment of the present application can realize the acquisition of the erasure code coding pattern in the identification tag 1 through the information acquisition device 2, and transmit the erasure code coding pattern to the parser 3, so that the parser 3 realizes the decoding of the erasure code coding pattern, and obtains the information carried by the erasure code coding pattern. Thus, when the information on the information code coding bit on the identification tag 1 is damaged or the decoding has errors, the information carried by the error correction code coding bit can still be used for error correction by using the erasure code coding pattern, so that correct information is obtained, and the fault tolerance of the identification system is improved.
