Abstract：A solution of intelligent voice guide device based on RFID（radio frequency identification）and MCU（micro controller unit）technology is introduced in this paper. It elaborates the operating principle, and describes the hardware implementation and interface circuits between models in detail, also includes the software flow chart and algorithm. The test indicates that this guide system has many advantages such as to identify position intelligently, play recorded voice for long hours and renew voice easily. 

 

Key words：radio frequency identification；MCU（micro controller unit）；voice guide
