Abstract

Various embodiments of a jobsite keep out zone system are provided. The system includes one or more detectors configured to determine when an intruder is within and/or is approaching a protected area. In response to the determination, one or more alarms and/or notifications are generated.

First claim

What is claimed is:

1. A safety monitoring system comprising:
a first device configured to generate an alert providing an indication of a protected area on a construction site, wherein the alert comprises audio and/or visual elements;
a second device configured to generate an electronic signal in response to detecting an intrusion to the protected area; and
a third device remote from the second device, the third device configured to receive a notification that the intrusion was detected in the protected area.

2. The safety monitoring system of claim 1 , the second device configured to emit a laser along a periphery of the protected area.

3. The safety monitoring system of claim 2 , the first device comprising a detector configured to detect the laser.

4. The safety monitoring system of claim 1 , comprising:
a personal electronic device; and
a wire extending between the first device and the second device, the wire configured to emit a radio signal that is detected by the personal electronic device, wherein the personal electronic device is configured to emit a warning signal as a result of detecting the radio signal.

5. The safety monitoring system of claim 1 , comprising an elongate structure extending between the first device and the second device, wherein the second device is configured to monitor a length and/or a tension of the elongate structure.

6. The safety monitoring system of claim 1 , the second device comprising an accelerometer, wherein the detecting the intrusion to the protected area is a result of receiving a signal from the accelerometer.

7. The safety monitoring system of claim 1 , wherein the third device is remote from the protected area.

8. The safety monitoring system of claim 1 , wherein the electronic signal received by the third device comprises a text message.

9. The safety monitoring system of claim 8 , wherein the notification comprises the text message.

10. The safety monitoring system of claim 8 , wherein the text message comprises information identifying an intruder that caused the intrusion.

11. The safety monitoring system of claim 1 , the third device comprising a hard hat.

12. The safety monitoring system of claim 11 , the hard hat comprising a lighting element configured to emit a light in response to receiving the notification that the intrusion was detected in the protected area.

13. The safety monitoring system of claim 11 , the hard hat comprising a haptic element configured to vibrate in response to receiving the notification that the intrusion was detected in the protected area.

14. A safety monitoring system comprising:
a first device configured to generate an electronic signal in response to detecting an intrusion to a protected area on a construction site; and
an electric tool configured to:
receive a notification that the intrusion was detected in the protected area; and
generate a safety alarm in response to the detection of the intrusion.

15. The safety monitoring system of claim 14 , wherein the electric tool is configured to disable a functionality in response to the detection of the intrusion.

16. The safety monitoring system of claim 14 , comprising a second device configured to detect a worker and/or the electric tool falling within the protected area, and to generate a second safety alarm in response to the detection of the falling of the worker and/or the electric tool.

17. A safety monitoring system comprising:
a first monitoring device configured to measure an atmospheric condition, to monitor the presence of a worker within a protected area on a construction site, and to generate a notification indicating the measurement of the atmospheric condition and the presence of the worker; and
a central server configured to:
receive the notification from the first monitoring device;
analyze the notification; and
transmit an alarm to the worker in response to the analyzing of the notification.

18. The safety monitoring system of claim 17 , the central server configured to transmit a second alarm to a second worker in response to analyzing the notification and in response to receiving data that the second worker is in the protected area.

19. The safety monitoring system of claim 17 , wherein the notification indicating the measurement of the atmospheric condition and the presence of the worker comprises a first signal indicating the measurement of the atmospheric condition and a second signal indicating the presence of the worker.

20. A method for monitoring a safety zone at a construction site comprising:
receiving a first signal indicating a first number of people in a protected area on a construction site;
receiving a second signal indicating the occurrence of an emergency event that corresponds to the protected area;
receiving a third signal indicating a second number of the people that were in the protected area; and
determining whether the protected area is evacuated by comparing the first number to the second number.

21. The method of claim 20 , comprising counting the second number of the people that were in the protected area via a personal electronic device scanning ID devices of each of the second number of the people.
