Multi-protocol Rfid Adapters Research

During these years, RFID (Radio Frequency Identification) has got wide attention both inside and outside of China. Many experts think it will become the industry star in future. But now, it doesn't form the globally uniform standard. It assuredly adds the developing complexity of RFID application system.In order to shield the standard difference between RFID physical devices and make the developing of application system more convenient. This subject makes deep research in RFID technology. Also based on the RFID middleware theory it developed the multiple protocol RFID adapter, RFID Server. The system makes technical innovation in the following aspects.(1) It uses XML to describe configure information and filtering rule.(2) It realizes the real time communication with application system.(3) It supports not only foreign RFID devices but also national RFID devices.The subject has studied the following key technologies.(1) Research on shielding the different communication interfaces between RFID devices and PC.(2) Research on shielding the different tag data formats.(3) Research on real time data communication between application system and RFID middleware.(4) Research on monitoring and controlling technology about RFID adapter.The research and development of multiple protocols RFID adapter system lighten the developing burden of RFID application system and solve the problem of real time data communication. It has significance for extending the application of RFID technology.
