Abstract

A method for determining positioning relative to utility lines. A first step involves providing a global positioning apparatus. A second step involves providing a processing unit with a display. The processing unit has stored in memory at least one geographical map depicting positioning of at least one utility line. A third step involves transferring data received from the global positioning apparatus to the processing unit and displaying on the display the positioning of the mobile machine relative to the at least one utility line on the at least one geographical map.

Claims

1. A method for determining positioning relative to utility lines, comprising the steps of:

providing a global positioning apparatus;

providing a processing unit with a display, the processing unit having stored in memory at least one geographical map depicting positioning of at least one utility line; and

transferring data from the global positioning apparatus to the processing unit and displaying on the display the positioning of the global positioning apparatus relative to the at least one utility line on the at least one geographical map.

2. The method as defined in claim 1, the global positioning apparatus being incorporated into the processing unit.

3. The method as defined in claim 1, the global positioning apparatus and the processing unit being mounted on a mobile machine.

4. The method as defined in claim 3, an operator alarm being in communication with the processing unit, the processing unit being programmed to trigger the operator alarm to alert an operator of the mobile machine should the mobile machine venture within a predetermined distance of a utility line.

5. The method as defined in claim 3, at least one mobile global positioning apparatus being provided which is adapted to be carried by a worker working in the vicinity of the mobile machine, the processing unit receiving signals from the at least one mobile global positioning apparatus and displaying on the display the positioning of the worker relative to the mobile machine.

6. The method as defined in claim 3, a detector being provided for detecting the presence of a worker within a predetermined distance of the mobile machine, the detector being linked to the processing unit, the processing unit being linked to an operator alarm to alert an operator of the presence of the worker.

7. An apparatus for determining positioning relative to utility lines, comprising:

a global positioning apparatus;

a processing unit with a display, the processing unit having stored in memory at least one geographical map depicting positioning of at least one utility line, the processing unit receiving data from the global positioning apparatus and displaying on the display the positioning of the global positioning apparatus relative to the at least one utility line on the at least one geographical map.

8. The apparatus as defined in claim 7, wherein the global positioning apparatus being incorporated into the processing unit.

9. The apparatus as defined in claim 7, wherein the global positioning apparatus and the processing unit are mounted on a mobile machine.

10. The apparatus as defined in claim 9, wherein an operator alarm is in communication with the processing unit, the processing unit being programmed to trigger the operator alarm to alert an operator of the mobile machine should the mobile machine venture within a predetermined distance of a utility line.

11. The apparatus as defined in claim 9, wherein at least one mobile global positioning apparatus is provided which is adapted to be carried by a worker working in the vicinity of the mobile machine, the processing unit receiving signals from the at least one mobile global positioning apparatus and displaying on the display the positioning of the worker relative to the mobile machine.

12. The apparatus as defined in claim 9, wherein a detector is provided for detecting the presence of a worker within a predetermined distance of the mobile machine, the detector being linked to the processing unit, the processing unit being linked to an operator alarm to alert an operator of the presence of the worker.

13. The apparatus as claimed in claim 12, the detector being one of an infrared scanner which responds to heat, a visual scanner which responds to shadows, proximity sensors which respond to objects, a transmitter which interogates a transponder carrried by the worker, a transceiver which communicates with a transceiver carried by the worker, or a radio beacon detector which responds to a radio transmitter carried by the worker.

14. The apparatus as defined in claim 7, wherein the processing unit has stored in memory for display, upon demand, critical data relating to each of the at least one utility line, such as the nature of the utility line and an emergency contact information of an owner.

15. The apparatus as defined in claim 7, where the at least one geographical map depicts positioning of all known utility lines in the vicinity.

16. The apparatus as claimed in claim 9, wherein there is provided a central monitoring station to monitor the positioning of the mobile machine, the central monitoring station receiving data from the global positioning apparatus mounted on the mobile machine, the central monitoring station having a central processing unit with a central display, the processing unit having stored in memory at least one geographical map depicting positioning of at least one utility line, the central monitoring station receiving data from the global positioning apparatus and displaying on the cental display the positioning of the mobile machine relative to the at least one utility line on the at least one geographical map, two way communication being provided between the central monitoring station and the mobile machine.

17. An apparatus for determining positioning relative to utility lines, comprising in combination:

a global positioning apparatus adapted for mounting on a mobile machine;

a processing unit with display adapted for mounting on the mobile machine, the processing unit having stored in memory a series of geographical maps depicting positioning of all known utility lines, along with critical data relating to each of the known utility lines, such as the nature of the utility line and an emergency contact information of an owner, the processing unit receiving data from the global positioning apparatus and displaying on the display the positioning of the mobile machine relative to the known utility lines on one of the series of geographical maps; and

an operator alarm in communication with the processing unit, the processing unit being programmed to trigger the operator alarm to alert an operator of the mobile machine should the mobile machine venture within a predetermined distance of one of the known utility lines.

18. The apparatus as defined in claim 17, wherein at least one mobile global positioning apparatus is carried by a worker working in the vicinity of the mobile machine, the processing unit receiving signals from the at least one mobile global positioning apparatus and displaying on the display the positioning of the worker relative to the mobile machine.

19. The apparatus as defined in claim 17, wherein a detector is mounted on the mobile machine for detecting the presence of a worker within a predetermined distance of the mobile machine, the detector being linked to the processing unit, the processing unit being linked to the operator alarm to alert an operator of the presence of the worker.

20. The apparatus as claimed in claim 19, wherein the detector is one of an infrared scanner which responds to heat, a visual scanner which responds to shadows, proximity sensors which respond to objects, a transmitter which interogates a transponder carrried by the worker, a transceiver which communicates with a transceiver carried by the worker, or a radio beacon detector which responds to a radio transmitter carried by the worker.
