Study Of RFID Reader Receiver Based On Internet Of Vehicles

Car networking is an emerging industry which is the combination of two areasincluding the Internet of things and smart car. The objects in the iot into the vehicle and roadfacilities, that is car net working. In recent years, the development of the intermit makes theinformation industry get great progress and car networking also received attention andsupport from all walks of life. From the main key technologies In the car networking, thispaper mainly studied on RFID technology. RFID is a new technology of non-contactautomatic identification which booms up in recent several years. This is a new technologyuse radio frequency signal to achieve non-contact message transmission by means of spacecoupling(alternating magnetic field or electromagnetic field). Radio frequency identificationtechnology (RFID) is a kind of information shall be transmitted by wireless waynon-contact automatic identification technology. At the present, the development of RFIDtechnology is rapid in both theory and practice aspects. At the present time，both in theoryand practice application aspects，it comes to the front more and more. And the UHF RFIDtechnology is the most advanced in the world. UHF band RFID has advantages of longidentification distance，speedy identification, relatively long life and so on which is appliedto these domain electric street nameplate， freeway charge，Logistics Management andStrategy and tracking of products. In the future few years，the development of UHF RFIDreader is perfect fore ground，for the technology of RFID will be instead of bar code step bystep and dominate in EPC. Ultra High Frequency (UHF) radio frequency identificationtechnology has recognition distance, short recognition practices, the use of long practice, etc,and is widely used in various fields.According to the Type C protocol of ISO/IEC18000-6, this paper designs andresearches the readers which work at Ultrahigh Frequency in the RFID systems, which basedon the detailed analysis on the relative theory and technology for UHF RFID. Firstly, thecomprehensive elaboration about fundamental technology of the whole RFID system ismade, Moreover, the basic principles of the system and its various components is introducedand analyzed, and the more researches on the technology of the6C protocol’s coding,modulation are made. This paper describes the status of the car networking and RFID systems. First,according to the theory and key technology of radio frequency identification technology,establish UHF RFID reader sent, Receiving circuit and a signal simulation is carried out,And put forward the basic principle of an rf front-end circuit diagram and the variouscomponents of circuit,then make the simulation and performance analysis of the circuit. Andthen introduced the180006C standard protocols, and compare the advantages anddisadvantages of the180006A, coding and modulation were studied in standard B. Finally,according to the theory and key technology of radio frequency identification technology,Introduces a centralized common receiver and proposed a zero-IF receiver optimizationmethod based on the characteristics of the receiver and zero the preceding analysis.Finally, the paper systematically analyzed the various kinds of factors which effect theperformance of the reader’s front-end RF. The paper builds the model of the radio frequencyidentification based on the research of theory, then simulates the transmitting circuit andreceiving circuit and inspects and verifies the theoretical analysis.
