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:

a radio frequency identification tag comprising;

a data block, for storing a destination information wherein the destination information comprising a destination position data;

a tag carrier, for designating the radio frequency identification tag as an admission ticket to a region defined by a set of GPS coordinates; and

an identification interface block, for storing a unique identification code used to distinguish the radio frequency identification tag from all other tags, and a GPS identification code used to determine whether to access the destination position data; and

a mobile apparatus, for use in navigation, comprising;

a radio frequency identification tag reading module, for accessing the destination position data stored in the radio frequency identification tag if the GPS identification code is recognized and determining whether the presence of the destination information is present and retrievable from said radio frequency identification tag based on the GPS identification code;

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. An identification tag navigation method, for receiving a destination information from a radio frequency identification tag to generate an direction instruction data, the method comprising steps of:

accessing a tag carrier embedded with the radio frequency identification tag designating the radio frequency identification tag as an admission ticket to a region defined by a set of GPS coordinates;

accessing a unique identification code used to distinguish the radio frequency identification tag from all other tags;

accessing a GPS identification code from the radio frequency identification tag;

checking whether the GPS identification code is recognized and determining whether the presence of the destination information is present and retrievable from said radio frequency identification tag based on the GPS identification code;

accessing the destination information from the radio frequency identification tag if the GPS identification code determines whether access to the destination information should occur, wherein the destination information comprises a destination position data;

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

computing a navigation route data according to the destination position data, the current position data, and a geographical data; and

providing a direction instruction according to the navigation route data and the current position data.

8. The identification tag navigation method as claimed in claim 7, wherein the plurality of reference signals comprises a plurality of satellite signals.

9. The identification tag navigation method as claimed in claim 7, wherein the direction instruction is generated by a plurality of direction indicator lights.

10. The identification tag navigation method as claimed in claim 7, wherein the direction instruction is generated by a sound module.

11. A radio frequency identification tag navigation apparatus, for receiving a destination information from a radio frequency identification tag having an embedded tag carrier designating the radio frequency identification tag as an admission ticket to a region defined by a set of GPS coordinates to generate direction instruction data, the apparatus comprising:

a radio frequency identification tag reading module, for accessing a unique identification code used to distinguish the radio frequency identification tag from all other tags, and a GPS identification code, and accessing the destination information from the radio frequency identification tag if the GPS identification code is recognized and determining whether the presence of the destination information is present and retrievable from said radio frequency identification tag based on the GPS identification code, wherein the destination information comprises a destination position data;

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 further generating an instruction data according to the current position data and the navigation route data; and

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

12. The identification tag navigation apparatus as claimed in claim 11, wherein the apparatus further comprises:

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

13. The identification tag navigation apparatus as claimed in claim 11, 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.

14. The identification tag navigation apparatus as claimed in claim 11, 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.
