Abstract
The utility model provides a radio frequency identification (RFID) reader-writer capable of automatically switching optical fiber and a 3rd-generation (3G) network to communicate. The RFID reader-writer comprises a microprocessor, wherein the microprocessor is respectively connected with a read-write module and an optical fiber module, is additionally provided with an optical fiber signal detection module and is additionally connected with a wireless communication module; and the wireless communication module is a 3G communication module. According to the RFID reader-writer, the 3G communication module which communicates with a base station through a 3G antenna is added to the original RFID reader-writer; the optical fiber is firstly utilized by the RFID reader-writer to transmit data; when the data packet loss rate of optical fiber transmission is greater than or equal to a preset threshold value, 3G dialing is conducted by the RFID reader-writer, and after the dialing succeeds, an optical fiber interface is closed and the data are uploaded through the 3G network; and when the data packet loss rate of the optical fiber transmission is detected to be less than the preset threshold value, the optical fiber transmission is switched back and the 3G dialing is interrupted. Thereby, real-time transmission of the data of the RFID reader-writer is guaranteed and the reliability and the adaptability of data transmission are improved.
