VxWorks下RFID读写器的网络接入设计

DESIGNING RFID READER′S NETWORK ACCESS BASED ON VXWORKS

RFID应用环境中拥有大量的嵌入式设备,由于特殊的硬件环境和网络条件,以VxWorks为代表的主流实时嵌入式操作系统成为这个领域的首选。为了保证RFID应用系统的可靠性,基于VxWorks的信息传输方案的选择就显得格外重要。以VxWorks中的设备操作技术和数据通信机制为依托,提出一种VxWorks下基于以太网传输的RFID数据采集系统的接入方案,解决VxWorks下多类型RFID读写器的抽象,为各种类型的读写器提供向上统一的接口,从而保证VxWorks下以太网传输RFID信息的实时性和完整性。

RFID application environment has a large number of embedded devices. As the special hardware and network environment, VxWorks has become the first choice as the representative of the mainstream of real-time embedded operating system in this area. In order to en- sure the reliability of the RFID application system, the choice of information transmission solution based on VxWorks has become more impor- tant. Based on the operating equipment technology and data communication mechanism in VxW^rks, this paper proposes an Ethernet access scheme for RFID data acquisition system. The scheme can support multiple kinds of RFID readers with an unified interface and provide the real-time and reliable data transmission for RFID data acquisition system.
