Abstract

The present invention provides a method and apparatus for monitoring the operation of a mobile machine. The machine includes a mobile communicator adapted to communicate with a remote monitoring station. The method includes the steps of receiving a configuration message from the remote monitoring station via a wireless communication link, comparing at least one of a current machine position to the configuration information a current machine time of operation to the configuration message, and sending an alarm message to the remote monitoring station in response the comparison.

1. A method for monitoring the operation of a mobile machine, the machine including a mobile communicator adapted to communicate with a remote monitoring station, comprising the steps of:

receiving a configuration message from the remote monitoring station via a wireless communication link, said configuration message including at least one of a geographic data packet and a time data packet, said geographic data packet identifying at least one monitoring region, and said time data packet including a desired time of operation of the machine;

comparing at least one of a current machine position to said monitoring region and a current machine time of operation to said desired time of operation; and

sending an alarm message to the remote monitoring station in response said comparison.

2. A method, as set forth in claim 1, wherein said geographic data includes a monitoring activation time and a monitoring deactivation time associated with each of said monitoring regions, said monitoring position being monitored between said activation time and said deactivation time.

3. A method, as set forth in claim 2, wherein each said monitoring region includes an associated monitoring type, said monitoring type including one of an exclusion monitoring indicator and an inclusion monitoring indicator.

4. A method, as set forth in claim 3, wherein said geographic data includes a radius for each of said monitoring regions.

5. A method, as set forth in claim 4, wherein said geographic data includes a center point for each of said monitoring regions, further comprising the step of determining said monitoring region in response to said center point and said radius.

6. A method, as set forth in claim 4, further comprising the step of determining said monitoring region in response to said radius, and said current position of said machine.

7. A method, as set forth in claim 4, further including the step of notifying an end-user of an alarm in response to the remote monitoring station receiving one of a time of operation alarm and a monitoring region alarm.

8. A method, as set forth in claim 7, wherein the step of notifying said end-user includes the step of delivering one of an e-mail, a facsimile, a page, and a visual indicator to said end-user.

9. A method, as set forth in claim 8, wherein the step of notifying said end-user includes the step of accessing a reaction table, said reaction table including and end-user identifier and a end-user defined notification technique.

10. A method, as set forth in claim 9, including the step of delivering a partial configuration packet to said remote monitoring station from said end-user, said partial configuration packet including at least one of said geographic packet and said time of operation packets.

11. A method, as set forth in claim 9, wherein said wireless communication media includes one of a satellite communication link and a cellular telephone link.

12. A method, as set forth in claim 11, wherein the step of comparing said current position includes the steps of:

setting an alarm when said current position is outside said monitored region and said inclusion monitoring is being performed; and

setting said alarm when said current position is inside said monitored region and said exclusion monitoring is being performed.

13. A method, as set forth in claim 12, further including the step of resetting said alarm in response to one of a reset message from a local data port message, a reset message from said remote monitoring station, a timer based expiration, and a position based resetting.

14. A method as set forth in claim 12, including the steps of:

resetting said alarm when said current machine position is inside said monitored region and said inclusion monitoring is being performed; and

resetting said alarm when said current machine position is outside said monitored region and said exclusion monitoring is being performed.

15. A method, as set forth in claim 14, wherein the step of comparing said current time of operation includes the steps of:

determining if said machine is running; and

setting an alarm when said current time of operation is outside said desired time of operation and said machine is running.

16. A method as set forth in claim 15, including the step of resetting said alarm when said machine is not running.

17. A method, as set forth in claim 15, including the step of displaying said monitoring region and said current machine position to an operator.

18. A method, as set forth in claim 17, wherein said operator is one of an on-board operator, a remote operator, and an end-user.

19. A method for monitoring the operation of a mobile machine, the machine including a mobile communicator adapted to communicate with a remote monitoring station, comprising the steps of:

receiving a configuration message from the remote monitoring station via a wireless communication link, said configuration message including at least one of a geographic data packet and a time data packet;

wherein said geographic data packet identifies at least one monitoring region;

wherein said time data packet includes a desired time of operation of the machine;

comparing a current machine position to said monitoring region;

comparing a current machine time of operation to said desired time of operation; and

sending an alarm message to the remote monitoring station in response to one of said position comparison and said time of operation comparison.

20. A system adapted to monitor the operation of a mobile machine, comprising:

21. A system, as set forth in claim 20, wherein said geographic data includes a monitoring activation time and a monitoring deactivation time associated with each of said monitoring regions, said monitoring position being monitored between said activation time and said deactivation time.

22. A system, as set forth in claim 21, wherein each said monitoring region includes an associated monitoring type, said monitoring type including one of an exclusion monitoring indicator and an inclusion monitoring indicator.

23. A system, as set forth in claim 22, wherein said geographic data includes a radius for each of said monitoring regions.

24. A system, as set forth in claim 23, wherein said geographic data includes a center point for each of said monitoring regions, and wherein said mobile communicator is adapted to determine said monitoring region in response to said center point and said radius.
