Abstract:

Aiming at the problem of unhandiness and less information in the traditional way of artificial navigation, this paper designs a portable intelligent navigation system by using the radio frequency identification technology. The navigation device plays the appropriate information by reading the ID number of an IC card which is placed in any location and it has the characteristics of long lifetime, high reliability and easy portability. This paper presents the principle of a noncontact IC card, the structure of navigation, the implementation of hardware and the algorithm of multilanguage mode switching, and it derives the algorithm of navigation under the multilanguage mode .The experiments show that the system is convenient in installation and has strong practicability and high reliability.

Key words: RFID;intelligent navigation;noncontact IC card
