Abstract

A marking system may hold a container from which markers are dispensed to mark the presence or absence of an underground facility in a dig area. The container may identify a marker characteristic regarding the markers in the container. The marking system may receive activation of a trigger, dispense a marker from the container when the trigger is activated, and store the marker characteristic and time data when the trigger is activated. In other embodiments, the marking system may dispense a marker, determine location data and/or time data, and substantially simultaneously trigger the dispensing of the marker and logging of the location data and/or the time data. The location data identifies a geographic location where the marker is dispensed and the time data identifies the time when the marker is dispensed.

Claims

1. A method for operating a marking apparatus that holds a marking dispenser for

marking the presence or absence of an underground facility in a dig area, comprising:

operating the marking apparatus in association with dispensing a marker from the marking dispenser onto the ground in the dig area to mark the presence or absence of the underground facility;

logging one or more data elements associated with operation of the marking apparatus in an electronic record of marking apparatus operation; and

analyzing at least part of the electronic record to provide an analysis result that is usable in evaluation of marking apparatus operation, wherein analyzing the electronic record is based on one or more of a type of marker dispensed, an amount of marker dispensed, a time of dispensing the marker and geographic coordinates where the marker was dispensed.

2. A method for operating a marking apparatus as defined in claim 1, further comprising transmitting selected information from the electronic record of marking apparatus operation to a remote device for analysis.

3. A method for operating a marking apparatus as defined in claim 1, wherein analyzing the electronic record comprises analyzing the electronic record to determine if a marking operation was performed in an acceptable manner.

4. A method for operating a marking apparatus as defined in claim 1, wherein analyzing the electronic record comprises indicating the dispensing of the marker on an electronic representation of the dig area.

5. A method for operating a marking apparatus as defined in claim 1, wherein analyzing the electronic record comprises reconstructing a marking operation and displaying the reconstructed marking operation on an electronic representation of the dig area.

6. A method for operating a marking apparatus as defined in claim 1, wherein analyzing the electronic record comprises using the electronic record to determine if a marking operation was performed in an acceptable manner, based on information from a ticket.

7. A method for operating a marking apparatus as defined in claim 1, wherein analyzing the electronic record uses one or more of a count of user activations, elapsed time of user activation and a weight of the marking dispenser to estimate an amount of marker dispensed from the marking dispenser onto the ground in the dig area and/or an amount of marker remaining in the marking dispenser.

8. A method for operating a marking apparatus as defined in claim 1, wherein the electronic record includes geographic coordinates where the marker was dispensed and wherein analyzing the electronic record includes using the geographic coordinates to track a location where the marker was dispensed onto the ground in the dig area.

9. A method for operating a marking apparatus as defined in claim 1, wherein the electronic record includes time data and wherein analyzing the electronic record includes using the time data to track a time when the marker was dispensed onto the ground in the dig area.

10. A method for operating a marking apparatus as defined in claim 1, wherein the electronic record includes marking information and wherein analyzing the electronic record includes using the marking information to determine if a correct marker was dispensed onto the ground in the dig area.

11. A method for operating a marking apparatus as defined in claim 1, wherein the electronic record includes marking information and wherein analyzing the electronic record includes using the marking information to determine a type and/or amount of marker dispensed onto the ground in the dig area.

12. A method for operating a marking apparatus as defined in claim 1, wherein the electronic record includes marking information and wherein analyzing the electronic record includes using the marking information to determine when to replace the marking dispenser.

13. A marking apparatus to mark the presence or absence of an underground facility in a dig area, comprising:

a housing configured to enable dispensing of a marker onto the ground for marking the presence or absence of an underground facility in a dig area;

a marking dispenser holder affixed to the housing to hold a replaceable marking dispenser;

an actuator to enable a user to cause dispensing of the marker from the marking dispenser onto the ground to mark the presence or absence of an underground facility in a dig area; and

a processing device to log one or more data elements associated with operation of the marking apparatus in an electronic record of marking apparatus operation and to analyze at least a part of the electronic record to provide an analysis result that is usable in evaluation of the marking apparatus operation, wherein the processor is configured to analyze the electronic record based on one or more of a type of marker dispensed, an amount of marker dispensed, a time of dispensing the marker and geographic coordinates where the marker was dispensed.

14. A marking apparatus as defined in claim 13, further comprising a communication system configured to transmit selected information from the electronic record of marking apparatus operation to a remote device for analysis.

15. A marking apparatus as defined in claim 13, wherein the processor is configured to analyze the electronic record to determine if a marking operation was performed in an acceptable manner.

16. A marking apparatus as defined in claim 13, wherein the processor is configured to analyze the electronic record by indicating the dispensing of the marker on an electronic representation of the dig area.

17. A marking apparatus as defined in claim 13, wherein the processor is configured to analyze the electronic record by reconstructing a marking operation and displaying the reconstructed marking operation on an electronic representation of the dig area.

18. A marking apparatus as defined in claim 13, wherein the processor is configured to analyze the electronic record by using the electronic record to determine if a marking operation was performed in an acceptable manner, based on information from a ticket.

19. A marking apparatus as defined in claim 13, wherein the processor is configured to analyze the electronic record by using one or more of a count of user activations, elapsed time of user activation and a weight of the marking dispenser to estimate an amount of marker dispensed from the marking dispenser onto the ground in the dig area and/or an amount of marker remaining in the marking dispenser.

20. A marking apparatus as defined in claim 13, wherein the processor is configured to log into the electronic record geographic coordinates where the marker was dispensed and is configured to analyze the electronic record by using the geographic coordinates to track a location where the marker was dispensed.

21. A marking apparatus as defined in claim 13, wherein the processor is configured to log into the electronic record time data and wherein the processor is configured to analyze the electronic record by using the time data to track a time when the marker was dispensed.

22. A marking apparatus as defined in claim 13, wherein the processor is configured to log into the electronic record marking information and to analyze the electronic record by using the marking information to determine if a correct marker was dispensed.

23. A marking apparatus as defined in claim 13, wherein the processor is configured to log into the electronic record marking information and to analyze the electronic record by using the marking information to determine a type and/or amount of marker dispensed.

24. A marking apparatus as defined in claim 13, wherein the processor is configured to analyze the electronic record to determine when to replace the marking dispenser.
