Abstract

A global status and position reporting system for a remote unit having a status and position transmit/receive unit with at least one status and/or event input connected to a respective status and/or event sensor for reporting at least one system status and/or event and position of the remote unit, and a status output connected to a communication interface; at least one base unit adapted for receiving a status and position report, disposed at a position spaced away from the remote unit; position independent communications means including communications interfaces respectively disposed in the remote unit and in the base unit for transmitting a status and position report from the remote unit to the base unit upon receipt of an activating prompt from the status sensor or a prompt initiated at the base unit. A global positioning satellite receiver is provided in the remote unit for receiving global positioning information from a system of global positioning satellites having a position output connected to the communications means for entering position information upon receiving the activating prompt.

Claims

1. A status and position reporting system comprising at least one movable remote unit, a plurality of bases disposed apart from said remote unit, status determining means and position determining means in said remote unit, status and position reporting means in said remote unit connected to said status determining means and said position determining means for reporting status information and position information pertaining to said remote unit, remote unit communication means in said remote unit connected to said status and position reporting means for communicating said status and position information from said remote unit to said base;

and base selection means in said remote unit connected to said status and position reporting means operative for selecting one of said bases in response to data in said status and position information.

2. A status and position reporting system according to claim 1, wherein said position determining means in said remote unit is operative for determining global position data for said remote unit.

3. A status and position reporting system according to claim 2, wherein said base selection means include a base selection table having coordinates for respectively receiving said status information and said position information, said base selection table having storage means for storing addressing information connected to an input of said remote unit communications means for addressing a selected one of said plurality of bases.

4. A status and position reporting system according to claim 3, wherein said addressing information includes identification data for said remote unit.

5. A status and position reporting system according to claim 3, wherein said addressing information includes alternate base selection data for selecting an alternate one of said bases in case a first selected base is unavailable.

6. A status and position reporting system according to claim 2, wherein said position determining means include a global positioning satellite receiver connected to an input of said position determining means.

7. A status and position reporting system according to claim 1, wherein said remote unit communications means include at least one remote unit communications interface disposed in said remote unit, said remote unit communications interface being operative for communicating said status and position information to said base.

8. A status and position reporting system according to claim 7, wherein said remote unit communications interface includes radio transmit/receive devices being adapted for communication with at least one of a satellite communications system, a cellular radio communications system, and a special radio communications system.

9. A status and position reporting system according to claim 1, wherein said status determining means include a plurality of status sensors, each adapted for reporting a respective remote unit status.

10. A status and position reporting system according to claim 1, wherein said status determining means includes at least one manual switch for manually reporting status information.

11. A status and position reporting system according to claim 1, wherein said status determining means include a voice transmitter/receiver for verbally reporting status information.

12. A status and position reporting system according to claim 1, wherein said status determining means is operative for reporting a plurality of statuses, and status selecting means connected to said status determining means for selecting one of said plurality of statuses.

13. A status and position reporting system according to claim 12, wherein said status selecting means include sequential status selecting means for sequentially selecting one of said statuses.

14. A status and position selecting system according to claim 13, wherein said sequential status selecting means include a counting chain having a plurality of counting stages, an equal plurality of AND-gates each having one input connected to a respective counting stage and another input connected to a respective status sensor, a clock generator for driving said counting chain, an OR-gate having an equal plurality of inputs each connected to a respective AND-gate output and an OR-gate output, a stop-flip-flop having a set input connected to said OR-gate output and a clear input connected to a response lead for clearing said stop-flip-flop upon receiving a response signal from said base.

15. A status and position reporting system according to claim 1, wherein said remote unit includes a stored program control for controlling said status determining means, and said position determining means, said stored program control composed of a central processing unit, a program and data memory connected to said central processing unit, and base selection tables included in said program and data memory.

16. A status and position reporting system according to claim 1, wherein said base includes at least one base communication interface operative for wirelessly communicating with said remote unit communications means, a manual console having an input connected to said base communications interface, and an information display connected to said manual console for visually displaying status information received from said remote unit.

17. A status and position reporting system according to claim 16, wherein said information display is adapted for displaying status and position information from said remote unit.

18. A status and position reporting system according to claim 16, wherein said information display is adapted for displaying remote unit identity information from said remote unit.

19. A status and position reporting system according to claim 16, including a plurality of remote units, further including a switching matrix in said base having a first plurality of matrix inputs, and a second plurality of matrix outputs, wherein at least one of said matrix inputs is connected with said base communication interface.

20. A status and position reporting system according to claim 16, including a keyboard connected to said manual console for manually transmitting information to said remote unit.

21. A status and position reporting system according to claim 11 including a voice transmitter/receiver connected to said manual console for verbally communicating with said remote unit.

22. A status and position reporting system according to claim 19, including a landline communications interface connected to one of said matrix inputs for providing landline communication for said manual console.

23. A status and position reporting system according to claim 1, further including a clock and a time and position deviation table in said remote unit for containing anticipated time and position coordinates for said remote unit, said time and position deviation table having an output connected to said status and position reporting means for initiating a status report indicating actual deviation in time and position of said remote unit from said anticipated time and position coordinates.

24. A status and position reporting system according to claim 23, including table control means in said remote unit communicating with said time and position deviation table for remotely controlling said time and position deviation table from said base.

25. A status and position reporting system according to claim 3, including further table control means in said remote unit communicating with said base selection table for remotely controlling said base selection table from said base.
