Implementation And Application Of Two-dimensionalcode Research In Constructing Specimens In Laboratory

The content of this paper is the use of bar code technology management school specimen laboratory two-dimensional. This method will be the main information code stored specimens in 2D barcode, surface attached to the specimen, the teachers and students of two-dimensional bar code reading device scans the above through the learning process, relevant information can quickly obtain specimens, and by acquiring the site fast access site background, through the website can obtain knowledge a lot of. In the process of preparing specimens to the specimen, with two-dimensional bar code, you can track samples from whole process acquisition and processing, production, use. Can reduce the loss of samples in the process of matching error, etc.. Two dimensional bar code label than traditional card label area is small, the overall visual effect on specimens without affecting the specimens, and the two-dimensional bar code can be indicated more information than the traditional card. In the sample management process, quickly obtain the specimen information can use two-dimensional bar code, reducing the repetition of sample information. In the specimens of borrowing process can also tracking using two-dimensional bar code, improve the efficiency of the use of the specimens. In the process of teaching standard plant identification, students if they do not know when the specimen can be quickly obtained detailed information scanning two-dimensional bar code. The main work and results are as follows:Ⅰ)Firstly, analysis of typical two-dimensional bar code technology at home and abroad, makes an analysis and comparison of two dimensional bar code encoding and decoding characteristics and applications; the 2D bar code efficiency, reading speed, said digit, aspects of anti fouling ability and environment to analyze the ratio; the QR Code two-dimensional barcode as identification scheme specimen laboratory.Ⅱ)The technical characteristics and operating points of QR Code two-dimensional barcode encoding and decoding are analyzed. According to the system of two-dimensional bar code using the poor environment, the two-dimensional bar code anti fouling ability request is higher, the improved method of QR Code two-dimensional barcode decoding error correction algorithm is proposed. Replace the RS code using the original LDPC code, improving the error correcting ability of two-dimensional bar code.Ⅲ)The system analysis of information management system of the laboratory specimens, business process and business analysis system, hardware and software design, gives the system design, the system feasibility, usability, security is also analyzed, gives a two-dimensional bar code on the tracking of specimen collection, processing, production, the use of teaching process application method.IV)The QR two-dimensional bar code and implementation process were completed in the laboratory application, according to the demand of the system, establish the specimen laboratory database design, according to the design demand complete specimen laboratory management system platform. Were data information input through this system can track, specimen collection, processing, use of the whole process from the establishment of management; samples; specimen learning website, students can through the website to find all kinds of specimen information data.
