Abstract
With the development of science and technology, Radio Frequency Identification is used in many field. The title of the design in which LPC932 single-chip microcontroller is the microcontroller, and nRF905 is single-chip radio transceiver of the whole system is radio frequency indentification system sending and receiving circuit. There are two parts including the whole system: radio frequency sending circuit and radio frequency receiving circuit. In the sending part, the circuit could realized the function of sending peoples’ informations, and the content shoud be received in the range of 10 meters by the receiving part, displaying by LCD and speaking by audio circuit. Moreover, to transmit the receiving content to PC by serial communication circuit is one of function of the receiving terminal. Designing a electronic system, there are all kinds of interferences, thus, to carry out anti-interference measures to the system hardware is very important. Because of the system has the features of minute extension, wireless and intelligentize, which is used every field, and will have a nice development in the future.
