Embodiment Construction

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0030] The invention provides a component traceability method and a component identification method to solve the problem in the prior art that the component identification is easily damaged and affects its traceability effect.

[0031] Specifically, such as figure 1 shown, including:

[0032] S101. Obtain the identification code on the component; the identification code includes a two-dimensional code;

[0033] S102. Analyze the identification code according...

Abstract

The invention discloses a part tracing method and a part identifying method. The part tracing method and the part identifying method are based on a two-dimensional code. Production information is encoded according to a preset encoding rule to obtain the corresponding two-dimensional code, and the two-dimensional code is printed on a part to identify the part; correspondingly, the two-dimensional code on the part is identified and parsed to acquire generation information of the part, and the part is traced. Due to the fact that the identification degree of the two-dimensional code is high, the two-dimensional code can be correctly identified and read even the two-dimensional code is partially damaged by perforation, contamination and the like, and the largest damaging area for guaranteeing correct identification can be up to 50 percent. Therefore, compared with a method for identifying and tracing by a plain code in the prior art, the part tracing method and the part identifying method have the advantages that the success rate and accuracy for tracing parts are improved, and the problem that tracing is failed when an identification code is damaged is solved to a great extent. Compared with the plain code, the two-dimensional code has the advantages of high fault-tolerant ability and a fault-correcting function; the amount of information storage is large, so that the part tracing method and the part identifying method have more advantages than the prior art.

Description

technical field [0001] The invention relates to the technical field of component identification, in particular to a component tracing method and a component identification method. Background technique [0002] Parts in the prior art are mainly marked with clear codes. According to the clear codes, the manufacturers who use the parts can know the suppliers of the parts and their production batches, etc.; The use of the parts by the manufacturer is easy to cause damage. Once the clear code is perforated during use, or local damage is caused by contamination, the clear code can no longer be identified, making it impossible to trace the information of the parts . Contents of the invention [0003] In view of this, the present invention provides a component traceability method and a component identification method to solve the problem in the prior art that the component identification is easily damaged and affects its traceability effect. [0004] In order to achieve the abov...
