| Along with economy's development, traveling and display have played a new role in economic growth. People show more interests in exhibition hall related about traveling with leisure sightseeing and technical culture information, in addition, people become more independently and long for personalized traveling extremely therefore they choose travel route to their idea, which gives the reason why knowledge tour, the intelligent tour, personal travel are on the way to develop.In the article an intelligent audio guiding system based on radio frequency identification technology is developed because of its advantages over localization, object tracking and intelligent management, including popular MCU control technology. This system is for the purpose of good use of nature, technical resources.System function demand is analyzed first. The working principle and structure design are introduced. The chips are determined. The design and implementation of hardware part includes automatic identification circuit, control circuit, audio storage module, D/A and audio amplification circuit are expounded. Then software design is expatiated. The flow chart of USB interface, FAT, audio broadcasting, and serial interface are given. Finally the system test is finished in the building.The result indicates that the system characterizes in intelligence, independence, high fidelity and good practicability. It is not limited by guider and route, and its content is rich and objective and easily updated, what is important in its ability of area identification. |
