Application Research On The Multi-dimensional Code Combination In The Composition Tracing Of Computer

With the development of science and technology,computers have entered thousands of families.Whether name-brand computer or assembly computer,the computer has always been composed of major components.Facing a huge computer users,after-sales maintenance has become a problems for computer vendor.Due to the assembly characteristics of the computer,the user can replace parts by themselves.For the computer vendor,the machine state identification is very important work,so testing computer chassis,power supply,motherboard and other configuration of the factory state and sent to the maintenance,repair status is consistent.Therefore,the using information technology in the computer form of retrospective state is very necessary.The important significance of Using information technology in computer form the status of retrospective: do a good job in maintenance work,do a good job of maintenance and information technology in the application of the product.In this paper,the problem of computer component status back problem analyzed and in the external market environment,most computer vendors do not have the same of computer component identification.The paper summarizes the research results at home and abroad,the concept of bar code,features and the application of bar code technology at home and abroad in-depth discussion of the composition of the computer and the bar code label application and technology,A computer component traceability system combining the two-dimensional QR code of the whole computer and the unified one-dimensional component identification code is established and the one-dimensional code standard of the computer component is formulated.And through the application of examples to help computer vendors to improve service levels of maintenance work,good maintenance work,and better development of computer maintenance market,and better meet the increasingly diverse computer users,personalized needs,to enhance computer assembly Business competitiveness of the purpose.But also shows that the feasibility of the system and the effectiveness of the retrospective system for computer retailers to better provide services to customers to do the information technology to achieve the bedding.
