A design of self-service speech explaining system based on RFID

With the development of tourism, intelligent electronic tourism guides are welcomed widely. In this paper, a self-service tourism guide system based on RFID was designed. The system consists of RFID tags and handheld terminals. Handheld terminal includes ZLG500BTG⁺ module, VS1003 audio decoder module, SD card data storage module. It implants FAT32 file system, and can use data redirection function to deal with data, which makes the microcontroller complete the main control function of the whole system with less hardware resources. The system is suitable for the museums, exhibitions, and other intensive places.
