Automatic Identification System Application certain identification devices, automatic identification of items of access to relevant information and provide it to the background of the computer processing system to complete the relevant follow-up treatment, in recent decades it on a global scale has been rapid development in the community fields have played a key role. In a variety of automatic identification technology , radio frequency identification technology is the most promising because it is safe, reliable, rapid data collection , as hardware costs continue to decrease , radio frequency identification technology and more obvious advantages , will become twenty-one automatic identification century mainstream technology . RFID system consists of reader, antenna, tag and other hardware devices and data acquisition, processing middleware software. In this paper, RFID systems composed of hardware and software system structure and working principle of a detailed , systematic study, in which the study focused on data collection middleware . Middleware is a complex data acquisition subsystem , which includes the data smoothing and filtering reader coordination and integration of data routing , process management , data security management , and other aspects of the external interface . In this paper, using STU650A type reader , Tag-it HF-I -type electronic tags and other hardware devices and Jbuilder9.0, Visual C 6.0, SQL Server and other software systems to achieve a complete radio frequency identification system , which according to the data collection center pieces of ideas to achieve a data acquisition module . Data acquisition module implements reader management, data format conversion, data filtering , data buffering , data storage and other functions. Finally, the path tracking and home-school system , this paper shows the radio frequency identification system wide application prospect . In both systems , the identification object is encoded as digital code are then written to the tag , this tag data have a practical sense , they represent the actual product or a student. This paper focuses on the collection of data processing systems and applications , showing the superiority of the data acquisition system for the future will be in the social production and life , and its practical application has accumulated valuable experience .
