Abstract

An identification tag navigation system and a method thereof are provided according to the invention. The system comprises at least an identification tag and a mobile apparatus. The method comprises steps of receiving a destination reading command, accessing a destination information of the identification tag, receiving a plurality of reference signals and computing a current position data according to the plurality of reference signals, computing and generating a navigation route data according to the destination position data and the current position data, and generating an instruction data according to the navigation route data and the current position data.

Claims

1. An identification tag navigation system, comprising:

an identification tag, for storing a destination information wherein the destination information comprising a destination position data; and

a mobile apparatus, for use in navigation, comprising;

an identification tag reading module, for accessing the destination position data stored in the identification tag;

a position module, for receiving a plurality of reference signals to generate a current position data;

a memory, for storing a geographical data;

a navigation module, for generating a navigation route data according to the destination position data, the current position data, and the geographical data, and for further generating an instruction data according to the current position data and the navigation route data; and

an indicating module, for indicating a direction instruction according to the instruction data.

2. The identification tag navigation system as claimed in claim 1, wherein the mobile apparatus further comprises:

a destination setting button, for triggering the identification tag reading module to access the identification tag.

3. The identification tag navigation system as claimed in claim 1, wherein the indicating module comprises a plurality of direction indicator lights mounted on a main body of the mobile apparatus, for providing a direction instruction by flashing according to the instruction data.

4. The identification tag navigation system as claimed in claim 1, wherein the indicating module comprises a sound module mounted in the mobile apparatus for providing a direction instruction by a sound effect or a voice according to the instruction data.

5. The identification tag navigation system as claimed in claim 1, wherein the plurality of reference signals comprises a plurality of satellite signals.

6. The identification tag navigation system as claimed in claim 1, wherein the instruction data is a motion route from a current position to a destination position.

7. The identification tag navigation system as claimed in claim 1, wherein the identification tag comprises:
