Abstract

The present disclosure relates to a method for real time monitoring of the current status of a construction site having one or more work machines, wherein a monitoring means installed at least one work machine monitors the environment of the work machine in real time and generates corresponding monitoring data, with the generated monitoring data being transmitted by the monitoring means to at least one processing unit for a real time evaluation of the current construction site status.

First claim

The invention claimed is:

1. A method, comprising:
collecting monitoring data of a construction site via a plurality of sensors coupled to one or more cranes;
transmitting the monitoring data to a central processing unit;
comparing the monitoring data and a sample time of the monitoring data to a predetermined construction schedule;
detecting a scheduled event has not occurred within a threshold of a scheduled time based on the comparison; and
activating an alarm responsive to detecting the scheduled event has not occurred,
wherein detecting the scheduled event has not occurred within the threshold of the scheduled time based on the comparison includes detecting that the scheduled event has occurred too early to be within the threshold of the scheduled time.

2. The method of claim 1 , wherein detecting the scheduled event has not occurred within the threshold of the scheduled time based on the comparison includes detecting that the scheduled event has occurred too late to be within the threshold of the scheduled time.

3. The method of claim 1 , wherein detecting the scheduled event has not occurred within the threshold of the scheduled time based on the comparison includes detecting that the scheduled event has not occurred at all, including within the threshold of the scheduled time.

4. The method of claim 1 , wherein the plurality of sensors coupled to the one or more cranes are 3D scanners.

5. The method of claim 1 , wherein the plurality of sensors includes a lifting hook sensor system positioned in a lifting hook region of a first crane of the one or more cranes.

6. The method of claim 1 , wherein the one or more cranes is a plurality of cranes, wherein the plurality of sensors further include a first boom counter-ballast sensor system positioned in a boom counter-ballast region of a first crane of the plurality of cranes.

7. The method of claim 6 , wherein the plurality of sensors include a second boom counter-ballast sensor system positioned in a boom counter-ballast region of a second crane of the plurality of cranes.

8. The method of claim 1 , wherein the central processing unit is remote from the construction site.

9. A system, comprising:
a plurality of sensors coupled to one or more cranes positioned in a construction site;
a central processing unit comprising instructions stored in non-transitory memory executable to:
receive monitoring data from the plurality of sensors;
compare the monitoring data and a sample time of the monitoring data to a predetermined construction schedule;
detect a scheduled event has not occurred within a threshold of a scheduled time based on the comparison; and
activate an alarm responsive to detecting the scheduled event has not occurred,

wherein at least one of the plurality of sensors is positioned at a lifting hook region of one of the one or more cranes.

10. The system of claim 9 , wherein detecting the scheduled event has not occurred within the threshold of the scheduled time based on the comparison includes detecting that the scheduled event has occurred too early to be within the threshold of the scheduled time.

11. The system of claim 9 , wherein the plurality of sensors includes 3D laser scanners, each of the 3D laser scanners coupled to a respective crane of the one or more cranes.

12. The system of claim 11 , wherein data detected by each of the 3D laser scanners is transmitted to crane controls of the respective crane for each of the 3D laser scanners.

13. The system of claim 12 , wherein the data detected and transmitted to the crane controls is then sent from the crane controls to the central processing unit as the monitoring data.

14. The system of claim 9 , wherein at least one of the plurality of sensors is positioned at a counter-ballast region of one of the one or more cranes.

15. A method, comprising:
receiving monitoring data of a construction site collected via a plurality of sensors coupled to one or more cranes at a central processing unit;
comparing the monitoring data and a sample time of the monitoring data to a predetermined construction schedule via the central processing unit;
detecting a scheduled event has not occurred within a threshold of a scheduled time based on the comparison;
activating an alarm responsive to detecting the scheduled event has not occurred; and
further evaluating crane movement of the one or more cranes based on the monitoring data,
wherein evaluating the crane movement includes detecting a movement that was not scheduled to occur.

16. The method of claim 15 , wherein the one or more cranes are operated via systems that are controlled based on a digital clock tied to an actual time.

17. The method of claim 15 , wherein detecting the scheduled event has not occurred within the threshold of the scheduled time based on the comparison includes detecting that the scheduled event has occurred too early to be within the threshold of the scheduled time.
