Barcode wireless acquisition and analysis system design based on LabVIEW
Abstrct
Nowadays, due to the bar code technology is fast, accurate, low cost, high reliability, it has become the most practical outcome in information technology and played a very inportanrt role in the development and construction of the national economy. Therefore, whether in theory or practical application, bar code identification system research are quite far-reaching significance, how to do it quickly and accurately identifying become an important area of research.
The design of a comprehensive analysis of the actual needs of today's market for bar code identification system, through research and comparative advantages and disadvantages of the prior art barcode recognition, barcode design wireless acquisition and analysis system for based on LabVIEW. The design chosen CC2530 chip as the CPU, the application of ZigBee protocol, thereby effectively increasing the communication distance. The design of the system enables bar code data collection, transmission and status display, alarm and other functions. LabVIEW while developing PC software management platform for analysis identifying barcode, barcode scanning can reduce the error rate and enhance the error correction capability in the field of automatic identification bar code has broad application prospects.
