Alert system with zoning using wireless portable detectors and a central station
First Claim
1. A method comprising:
- providing a site/floor map of a predefined area of a facility to a central station;
configuring, by the central station, a plurality of zones in the predefined area of the facility;
receiving, by the central station, ambient gas condition data and location data from a plurality of wireless gas detector devices located in the predefined area, wherein the plurality of wireless gas detector devices comprises one or more portable gas detector devices, each of which is worn by an individual located within the predefined area;
computing, by the central station, an alarm level for each zone in the plurality of zones of the facility based on the received ambient gas condition data and location data;
determining, by the central station, whether each zone of the plurality of zones in the predefined area of the facility is an active zone due to detection of an alarm condition; and
in response to determination of one or more active zones, tranmitting, by the central station, an alert notification to each of the plurality of wireless gas detector devices within the active zones in the predefined area of the facility, wherein the alert notification sent to each wireless gas detector device includes an indication of relative safety based on the computed alarm level of the zone in which that wireless gas detector device is located relative to the computed alarm level of the other zones in the plurality of zones; and
determining, by the central station, whether any wireless gas detector device is not within at least one of the active zones but is approaching at least one of the active zones; and
in response to determination that one or more gas detector device is approaching at least one of the active zone, sending a pre-alert notification to the one or more wireless gas detector devices that is approaching at least one of the active zones.

Abstract
A system and method of monitoring zones for alarm conditions and automatically alerting individuals in a plurality of zones about the safety of a particular zone is provided. The method includes providing a site map of a predefined area, configuring a plurality of zones in the predefined area, receiving ambient condition data and location data from a plurality of wireless devices located in the predefined area, computing an alarm level for each zone in the plurality of zones based on the received ambient condition data and location data, and transmitting alert notifications to the plurality of wireless devices. The alert notification sent to each wireless device is based on the computed alarm level of the zone in which that wireless device is located relative to the computed alarm level of the other zones in the plurality of zones.

17. A central station comprising:
-
circuitry that configures a plurality of zones in a predefined area of a facility with one or more areas with potential for a gas leak hazard; circuitry that receives ambient gas condition data and location data from a plurality of wireless gas detector devices located in the predefined area; circuitry that computes an alarm level for each zone in the plurality of zones based on the received ambient gas condition data and location data; circuitry that, in response to determination of one or more active zones, transmits an alert notification to each of the plurality of wireless gas detector devices within the active zones in the predefined area of the facility, wherein the alert notification sent to each wireless gas detector device includes an indication of relative safety based on the computed alarm level of the zone in which that wireless gas detector device is located relative to the computed alarm level of the other zones in the plurality of zones; and circuitry that in response to determination that one or more gas detector device is approaching at least one of the active zone, sends a pre-alert notification to the one or more wireless gas detector devices that is approaching at least one of the active zones. - View Dependent Claims (18, 19, 20)
