RFID Reader's Design And Research Based On AT89S51 And CC1100

Radio Frequency Identification (RFID), as this century's most promising information technologies, has been attached great importance to the global industry. RFID represents a noncontact method for data transfer in object identification, has the advantages of high accuracy and ability to adapt to the environment, strong anti-jamming, fast operation and so on.This article describes the development process of the RFID, RFID industry status quo at home and abroad, ISO / IEC technical standards and technical standards for EPC Global, the advantages of RFID applications in logistics. RFID systems in accordance with the functions of different RFID systems can be divided into four types. And "Metro Future Store," for example, to study how to use ultra-high frequency second generation standards-based Checkpoint Systems, Impinj and Reva Systems, the introduction of the first supplier to the point-of-sale shop using RFID technology the problem.This article has designed one kind of simple low-cost reader, using AT89S51 and radio frequency transceiver CC1100. Protel software used to draw the reader hardware circuitry, and Proteus were the main part of the single-chip simulation.This article has studied the encoded form of communication between readers and tags, so as to data conversion for single-chip. In accordance with the characteristics of CC1100 send data, as well as the tag reader communication process, Choosed the right Tari, LF, DR, Calculated the time of communication TRcal, RTcal value, Has designed the single-chip reading label's flow chart.This paper has compiled one software which could communication with the single- chip. Compiles the serial port signal procedure, and add combo box in the main interface to select serial port communication parameter; Then has compiled the command button and the command parameter window, the command parameter window uses to change the command parameter; Finally has carried on the confirmation to the procedure.Has made the analysis to the microreader overall performance.
