Abstract

This invention discloses a control system and method thereof that is applied to a navigation apparatus. The system includes an apparatus body, a tag, a reader, a recognition module, and a processor. The apparatus body is mounted in the navigation apparatus to provide a navigation function. The tag is mounted on an object to provide a recognition data. The reader is used to detect and read the recognition data. The recognition module is used to compare the recognition data with a predetermined recognition data in order to generate a trigger signal. The processor is used to receive the trigger signal and then drives the apparatus body to perform a wakeup mode. If the processor does not receive the trigger signal in a determined period, the processor will drive the apparatus body to perform a sleep mode.

Claims

1. A control system applied to a satellite navigation apparatus, comprising:

an apparatus body installed in said satellite navigation apparatus for providing a navigation function;

a radio frequency identification (RFID) tag disposed on an object for providing a recognition data;

a reader installed in said satellite navigation apparatus for detecting and reading said recognition data;

a recognition module installed in said satellite navigation apparatus for comparing said recognition data with a predetermined recognition data;

if said recognition data matches said predetermined recognition data, then said recognition module will generate a trigger signal; and

a processor installed in said satellite navigation apparatus for receiving said trigger signal to drive said apparatus body to perform a wakeup mode;

thereby, if said processor does not receive said trigger signal in a predetermined period, said processor will drive said apparatus body to enter a sleep mode.

2. The control system of claim 1, wherein said reader periodically performs a detection.

3. The control system of claim 1, wherein said reader is a radio frequency identification (RFID) reader.

4. The control system of claim 1, wherein said satellite navigation apparatus is a personal digital assistant or an automobile satellite navigation apparatus.

5. The control system of claim 1, wherein said object is a key or a remote controller.

6. The control system of claim 1, wherein said object is a vehicle.

7. The control system of claim 1, wherein said recognition data is a radio frequency identification (RFID) code.

8. The control system of claim 1, wherein said predetermined recognition data is a radio frequency identification (RFID) code.

9. The control system of claim 1, wherein a light module, a sound module, or a GPS module is turned off under said sleep mode.

10. The control system of claim 1, wherein a light module or a sound module is turned on under said wakeup mode.

11. The control system of claim 1, wherein a GPS module is turned on under said wakeup mode on to perform a satellite positioning or execute a navigation function.

12. The control system of claim 1, further comprising a timing module for providing a timing function.

13. The control system of claim 1, wherein said predetermined period falls into a range from 5 minutes to 10 minutes.

14. The control system of claim 1, wherein said processor is a microprocessor or a microcontroller chip.

15. A control method applied to a satellite navigation apparatus having an apparatus body and a processor, and said apparatus body providing a navigation function, and said method comprising the steps of:

disposing a radio frequency identification (RFID) tag on an object to generate a recognition data;

installing a reader to said satellite navigation apparatus, and said reader being provided for detecting and reading said recognition data;

installing a recognition module to said satellite navigation apparatus, and said recognition module being provided for comparing said recognition data with a predetermined recognition data;

if said recognition data matches said predetermined recognition data, said recognition module will generate a trigger signal and send said trigger signal to said processor; and

if said processor receives said trigger signal, said processor will drive said apparatus body to perform a wakeup mode; and

if said processor does not receive said trigger signal in a predetermined period, said processor will drive said apparatus body to enter a sleep mode.

16. The control method of claim 15, wherein said processor is a microprocessor or a microcontroller chip.

17. The control method of claim 15, wherein said reader periodically performs a detection.

18. The control method of claim 15, wherein said reader is a radio frequency identification (RFID) reader.

19. The control method of claim 15, wherein said satellite navigation apparatus is a personal digital assistant or an automobile satellite navigation apparatus.

20. The control method of claim 15, wherein said object is a key or a remote controller.

21. The control method of claim 15, wherein said object is a vehicle.

22. The control method of claim 15, wherein said recognition data is a radio frequency identification (RFID) code.

23. The control method of claim 15, wherein said predetermined recognition data is a radio frequency identification (RFID) code.

24. The control method of claim 15, wherein a light module, a sound module, or a GPS module is turned off under said sleep mode.

25. The control method of claim 15, wherein a light module or a sound module is turned on under said wakeup mode.

26. The control method of claim 15, wherein a GPS module is turned on under said wakeup mode to perform a satellite positioning and execute a navigation function.

27. The control method of claim 15, further comprising a timing module installed onto said satellite navigation apparatus for providing a timing function.

28. The control method of claim 15, wherein said predetermined period falls into a range from 5 minutes to 10 minutes.
