Abstract

Embodiments relate generally to systems and methods for determining the location of a gas detector device, wherein the location may be within a predefined location zone, and automatically configuring the gas detector device based on the location zone. Each location zone in a facility may be associated with a configuration for the gas detector device. The location of the gas detector device may be monitored by a central station, and when it is determined that a gas detector device has moved from one location zone to another, the configuration of the gas detector device may be updated accordingly. Additionally, other parameters may be monitored by the central station and/or the gas detector device to determine the appropriate configuration of the gas detector device.

Claims

1. A method for configuring a gas detector device which has moved from a first location zone to a second location zone, the method comprising:

determining the gas detector device is in the second location zone, wherein the gas detector device is configured to hold a plurality of gas sensors at the same time and to activate or deactivate any number of the plurality of gas sensors at the same time;

deactivating a first sensor of the plurality of gas sensors in the gas detector device which is required to detect a first gas in the first location zone;

activating a second sensor of the plurality of gas sensors in the gas detector device which is required to detect a second gas in the second location zone; and

detecting the second gas, by the second sensor of the plurality of gas sensors in the gas detector device, in the second location zone.

2. The method of claim 1, further comprising:

alerting a user that the second gas in the second location zone is detected over a threshold, wherein the threshold is defined by a configuration of the gas detector device for the second location zone.

3. The method of claim 1, further comprising:

determining an identity of a user of the gas detector device; and

configuring the gas detector device based on the identity of the user, wherein the identity of the user is associated with a first threshold for the first gas and a second threshold for the second gas for alert.

4. The method of claim 1 further comprising:

determining a time of day when the gas detector device is in the first location zone;

wherein the time of day is associated with a threshold for alert of the first gas.

5. The method of claim 1, further comprising:

determining a time of day when the gas detector device is in the second location zone, wherein the time of day is associated with a threshold for alert of the second gas.

6. The method of claim 1, further comprising:

determining the gas detector device is in the first location zone;

detecting the first gas, by the first sensor of the plurality of gas sensors in the gas detector device, in the first location zone.

7. The method of claim 6, further comprising:

alerting a user when the first gas in the first location zone is detected over a threshold, wherein the threshold is defined by a configuration of the gas detector device in the first location zone.

8. The method of claim 1, wherein determining the gas detector device is in the second location zone comprises using wireless triangulation systems or global positioning systems to determine a location of the gas detector device is in the second location zone.

9. The method of claim 1, further comprising:

activating a third sensor of the plurality of gas sensors in the gas detector device which is required to detect a third gas in the second location zone, wherein the step of activating a third sensor is performed at the same time as the step of activating a second sensor; and

detecting the third gas, by the third sensor of the plurality of gas sensors in the gas detector device, in the second location zone.

10. The method of claim 1, further comprising deactivating a third sensor of the plurality of gas sensors which is required to detect a third gas in the first location zone, wherein the step of deactivating a third sensor is performed at the same time as the step of deactivating the first sensor.

11. The method of claim 1, further comprising altering an alert threshold of a third sensor of the plurality of gas sensors initially configured for detection of a third gas in the first location zone, wherein the third sensor was active in the first location zone and remains active in the second location zone, and wherein the step of altering the threshold is performed at the same time as the step of activating the second sensor.

12. The method of claim 11, wherein altering the alert threshold of the third sensor comprises configuring the alert threshold of the third sensor for detection of the third gas in the second location zone.

13. The method of claim 1, further comprising:

operating the gas detector device in default configuration, with all of the plurality of gas sensors simultaneously activated;

determining that the gas detector is located in the first location zone; and

responsive to determining that the gas detector is located in the first zone, deactivating one or more of the plurality of gas sensors, while leaving the first gas sensor active.

14. The method of claim 13, wherein operating the gas detector device in default configuration occurs upon powering up the gas detector device.

15. A method for configuring a gas detector device which has moved from a first location zone to a second location zone, the method comprising:

determining that the gas detector device is in the second location zone;

deactivating a first sensor of a plurality of gas sensors in the gas detector device which is required to detect a first gas in the first location zone;

activating a second sensor of the plurality of gas sensors in the gas detector device which is required to detect a second gas in the second location zone;

detecting the second gas, by the second sensor of the plurality of gas sensors in the gas detector device, in the second location zone;

activating a third sensor of the plurality of gas sensors in the gas detector device which is required to detect a third gas in the second location zone, wherein the step of activating a third sensor is performed at the same time as the step of activating a second sensor; and

detecting the third gas, by the third sensor of the plurality of gas sensors in the gas detector device, in the second location zone.
