The Research And Application Of RFID Used In The Major Hazard

AS the development of RFID technology and enlarge using of the major hazard, it is aimportant problem to solve it. IT needs us to develop a RFID system which compatible with themultiple standards. This paper put forward a Dual mode RFID system, and design the RFID reader.This RFID reader contains two RFID standards. One is13.56MHz,and the other is915MHz.Thetask of the reader is to identify two different standard RFID tag, and also could white data to thetwo kinds of RFID tag. In the hardware design, I used the STM32as the MCU, and use theTRF7970as the13.56MHz RFID module, use the AS3990as the915MHz module. After the test ofthe RFID system, it can almost complete the task, and work well.This paper is to complete the content as the followng,1.Study the background of major hazardand find the defects.2.Tell the meaning of the research.3.Analysis the principle of the RFIDtechnology.4.Research the products of RFID.5.Use ADS to analysis the circuit simulation.6.Designthe RFID system circuit.7.Give the solution that of RFID system used in the major hazard.
