| Abstract: | To implement the function of remote and real-time interaction on a UHF interrogator, the hardware and software design of a networked reader using LPC2138 as chief controller is put forward in this article based on Ethernet controller ENC28J60 and UHF RFID chip AS3990. The porting of real-time OS μC/OS-Ⅱand light weight IP protocol LwIP on the interrogator enables it to connect with the Internet, so as to comply with remote configuration and real-time data interaction, which meets the diverse demands of UHF readers in RFID industry well. |
