Two-dimensional matrix lattice and its generation method based on bcd coding for wheel hub traceability

Abstract

The invention relates to the field of artificial intelligence and automatic control and discloses a two-dimensional matrix dot matrix based on a BCD (Binary-Coded Decimal) code for tracing of a wheelhub. The two-dimensional matrix dot matrix based on the code for tracing of the wheel hub comprises a direction code, a check code and a plurality of code text units, wherein the direction code is located at the upper left corner of the two-dimensional matrix dot matrix and is used for representing an identification direction of the code text units; the check code is located at the last bit of thetwo-dimensional matrix dot matrix and is used for detecting the correctness of the code text units or correcting error-reading code text units; the plurality of code text units are sequentially located on remaining positions of the two-dimensional matrix dot matrix and is used for representing tracing information of the wheel hub; and the code text units, the direction code and the check code arein a 2*2 dot matrix structure. The two-dimensional matrix dot matrix for tracing of the wheel hub is simple in structure and high in identifiability; the two-dimensional matrix dot matrix can be increased and decreased, adjusted and deformed according to actual demands and is suitable for engraving and detection demands of the code texts under various complicated conditions, the check code is provided, thus the two-dimensional matrix dot matrix has a certain error prevention and error correction capabilities.

Description

technical field [0001] The invention relates to the automobile manufacturing industry, in particular to a two-dimensional matrix lattice based on BCD coding for wheel hub traceability and a generating method thereof. Background technique [0002] With the development of the automobile industry, the auto parts manufacturing industry is also developing at a high speed. Among them, the wheel hub manufacturing industry is developing the most rapidly. Therefore, the wheel hub industry is particularly critical for product quality traceability. At the beginning of the development of the wheel hub traceability system, manual marking is used. In the form of numbering the wheel hub, but the amount of information in it is very small, such as figure 1 As shown, it is limited to the internal circulation of the factory, and the traceability is not high. Usually, it can only be traced back to the casting shift. Moreover, the manual marking workload is heavy, the work content is tedious, th...

Problems solved by technology

[0005] The purpose of the present invention is to provide a two-dimensional matrix lattice based on BCD coding for wheel hub traceability and its generation method, which is used to solve the problem that the traditional QR two-dimensional code has a large area, can only use a matrix form, and has a rigid shape and no flexibility. The weight-reducing sockets of the hub flange and the spokes cannot provide effective marking space, the marking time is long, and the post-processing code text is damaged.
