| The traditional barcode technology has had many mature applications in logistics, books management, and other areas. As the key technology of information identification used in the internet of things,2D code expends barcode technology to more applications in other fields. With the increasing popularity of smart phones,2D code business based on mobile phones has got a good development and made our lives more convenient. So studying the technology of mobile phone platform and2D code has an important practical significance.This paper designs an item information management system based on the mobile phone platform and2D code. The content of this paper divides into the following parts.1. Study the current status of applications based on the technology of smart phone and21) code, analyze the popular realization methods of the information management systems, and then propose the overall designing scheme of this system.2. We chose QR code be used in this system after analyzing the characters of different2D codes. Study the structure features of QR code, coding and decoding rules. Analyze the image acquisition and processing method by camera device.3. Realize the function of QR code identification based on the MTK module and J2ME programming. Establish a wireless communication link between mobile phone platform and PC. Develop an information management system based on the Visual C++, to make an effective management of the information synchronized to PC.The functions of this system have been proved to be practical under the test. The result shows that the system designed can realize QR code identification, the data transmission and all the software functions perform well. During the development of this system, I have got some useful experience, I will be honored if it can do some help to the future development of similar systems.This paper contains36figures,12tables, and45references. |
