Abstract

A system and method for gas exposure monitoring of a work area are described. The system may include components that receive an alarm data item from a sensor device. The alarm data item may be generated in response to a first user being exposed to a gas concentration measured by the sensor device. A processor may receive a location of the sensor device in the work area based on a location identifier of the sensor device. A second user located within a predetermined vicinity of the sensor device may be identified. The second user may be identified by the processor. The system may transmit an indication of the alarm data item received from the first user and the location of the sensor device in the work area to the second user. The transmission may be automatic on detection of the second user's location.

First claim

We claim:

1. A method for providing real time locating and gas exposure monitoring, the method comprising:
receiving, by an interface, gas levels in a work area detected by respective multiple sensor devices in the work area indicative of gas emissions; and
receiving, by the interface, a location identifier associated with the respective sensor devices;
displaying, by a processor, on a display, a map of the work area; and
representing, by the processor, the gas emissions on the map of the work area, wherein the displayed map includes a representation of the gas levels at respective locations of the sensor devices, and wherein a size of the representation of the gas levels is proportional to the gas level.

2. The method of claim 1 , further comprising:
displaying, on the display, an alarm condition at a first location of a first sensor device based on a predetermined threshold being exceeded by a first gas level detected by the first sensor device of the multiple sensor devices.

3. The method of claim 1 , wherein a color of the representation of the gas levels is based on the respective gas levels.

4. The method of claim 1 , wherein at least one of the multiple sensor devices is a stationary sensor device.

5. The method of claim 1 , wherein at least one of the multiple sensor device is a sensor device carried by a user in the work area.

6. A method for providing real time locating and gas exposure monitoring of a work area, the method comprising:
receiving, by an interface, an alarm data item from a sensor device, the alarm data item being associated with a first user being exposed to a gas concentration measured by the sensor device;
identifying, by a processor, a location of the sensor device in the work area based on a location identifier of the sensor device;
identifying, by the processor, a second user located within a predetermined vicinity of the location of the sensor device;
receiving, by the processor, operator instructions to transmit the alarm data item;
in response to the operator instructions, transmitting, by the interface, for receipt by a communication device of the second user, an indication of the alarm data item received from the first user and the location of the sensor device in the work area; and
requesting an emergency response at the location of the sensor device based on a detection made by the second user.

7. The method of claim 6 , wherein the alarm data item is received in response to the sensor device detecting the first user being exposed to the gas concentration beyond a predetermined threshold.

8. The method of claim 6 , wherein the alarm data item is received in response to activation of a panic button coupled with the sensor device.

9. The method of claim 7 , further comprising receiving, by the interface, the gas concentration measured by the sensor device.

10. The method of claim 9 , further comprising transmitting the measured gas concentration to the communication device of the second user.

11. The method of claim 6 , further comprising receiving, from the communication device of the second user, an indication of whether an emergency responder should be contacted.

12. The method of claim 11 , further comprising initiating communication with a communication device of the emergency responder in response to the indication that the emergency responder should be contacted, or otherwise closing the alarm data item.

13. The method of claim 6 , further comprising:
displaying, on a display device, the gas concentration measured by the sensor device; and
prompting, on the display, for an operator to determine whether to transmit the indication of the alarm data item to the communication device of the second user.

14. The method of claim 6 , further comprising:
automatically transmitting, by the processor, the indication of the alarm data item to the communication device of the second user in response to identifying the second user as being within the predetermined vicinity of the location of the sensor device.

15. The method of claim 6 , wherein the sensor device is a mobile sensor device associated with the first user.

16. The method of claim 15 , wherein the communication device of the second user is a second sensor device associated with the second user.

17. A system comprising:
a plurality of hazard detection units in a work area; and
a controller configured to monitor hazardous conditions in the work area, the controller being configured to receive, from a first hazard detection unit of the plurality of hazard detection units, an alarm and a location of the first hazard detection unit, in response to the first hazard detection unit's detection of a predetermined hazardous condition;
the controller configured to identify the first hazard detection unit being within a work zone of the work area;
the controller configured to identify a second hazard detection unit of the plurality of hazard detection units within the work zone and within a predetermined distance from the first hazard detection unit;
the controller configured to transmit to the second hazard detection unit a request to check the safety of a user of the first hazard detection unit in response to the second hazard detection unit being within the work zone from which the alarm from the first hazard detection unit is received; and
the controller further configured to request an emergency response at the location of the first hazard detection unit based on a detection made by the second hazard detection unit.

18. The system of claim 17 , wherein the detection made by the second hazard detection unit is for the second hazard detection unit to detect a concentration of gas.
