Application And Research Of Two-dimensional Bar Code Technology In Motorcycle Accessories Identification

With the constant development of information technology, modernization construction of our railway information has made great achievements. Locomotive Depot as an important railway enterprise gradually introduced some of the information management system. Such as management information system of locomotive components, maintenance information system of locomotive accessories and so on. However, these systems are designed for a specific sector. Information can’t be interacted with other departments. The base data information of locomotive accessories are need the system of each department their maintenance; A large number of locomotive accessories circulation information is difficult to use timely for other sector and management; Several points above led to responsible of the individual nodes of circulation of locomotive parts cannot be tracked in real time. To solve these problems, the department information system must be a unified code of locomotive accessories. Therefore, Looking for a unique identification code of locomotive fittings must be enforced.This research is the use of two-dimension bar code technology on locomotive components to unify information encoding method. This method will save the motorcycle accessories identity code into the two-dimensional bar code, which is marked in the surface of the motorcycle accessories. It makes motorcycle accessories in the circulation of each node can scan its two-dimensional code reading device, and automatically connect to a local database. Not only does it avoid the repeated entry of basic information of locomotive fittings, and realized the interconnections between different information systems. The main tasks and results of this paper contain the following aspects:(1) Firstly, characteristics of the typical two-dimensional barcode PDF417, QR code and Data Matrix and the scope of application are described; Secondly, contrasting and analyzing according to two-dimension bar code technology advance, technology openness, Automated Management, and Application of generalized; At last, determining the two-dimensional bar-code system suitable for locomotive parts identification, Data Matrix bar-code.(2) Developing a coding principle of two-dimensional identification codes of locomotive fittings while referring to coding technology of railway materials, considering the characteristics of locomotive components, then determining the coding content, the length of coding and coding structure of locomotive fittings, at last working out two-dimensional identification codes of locomotive fittings, locomotive parts two-dimensional identification codes instance are given.(3) Taking into account the actual work environment of the locomotive fittings, identify factors of locomotive fittings and critical problems related to two-dimensional identification codes recognition have been analyzed and researched through code reading test, and the corresponding solutions were proposed.(4) Based on the above research, locomotive parts identification code generation system has been designed, which was built based on a database, and the coding process has been elaborated on this system.
