Abstract
Embodiments of the disclosure relate to systems and methods for isolating a base station beacon and gas reading transmission channel(s) based on a single radio wireless gas detection system. A gas detector may communicate on a first channel (e.g. a beacon channel) constantly listening to the base station beacon information. At a pre-defined interval (e.g. every 60 seconds), the gas detector radio may switch to a second channel (e.g. a data channel) to transmit gas reading data as well as the base station information to a central server. Software on the server may complete a triangulation algorithm to determine the location of the gas detector, using information obtained by the detector from the beacons.

16. A communication system for use in a facility comprising hazardous or harmful gas, the communication system comprising:
-
a central server configured to receive information from a plurality of devices; one or more access points located throughout the facility, wherein the access points communicate wirelessly with other devices within the facility; at least three beacons located within the facility, wherein the beacons transmit location information; one or more detector device located within the facility, wherein the detector device is configured to communicate with the beacons and the access points via wireless radio channels, and wherein the detector device comprises a single radio configured to switch between two or more radio channels, wherein; a first channel is used by the detector device to receive location data information from the one or more beacons, wherein the detector device communicates with the beacon when the detector device is in the range for that specific beacon; and a second channel is used by the detector device to communicate data to the central server via the one or more of the access points. - View Dependent Claims (17, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29)

30. A communication system for use in a facility comprising hazardous or harmful gas, the communication system comprising:
-
a central server configured to receive information from a plurality of devices; one or more access points located throughout the facility, wherein the access points communicate wirelessly with other devices within the facility; at least three beacons located within the facility, wherein the beacons transmit location information; one or more detector device located within the facility, wherein the detector device is configured to communicate with the beacons and the access points via wireless radio channels, and wherein the detector device comprises a single radio configured to switch between two or more radio channels, wherein; the detector device uses a first channel to receive location data information from the one or more beacons, wherein the detector device communicates with the beacon when the detector device is in the range for that specific beacon; the detector device uses a second channel to communicate data to the central server via the one or more of the access points; the detector device switches from the first channel to the second channel at a first pre-set time interval, and switches back to the first channel after a second pre-set time interval; the data communicated from the detector device comprises gas sensor data, location data, identification data, time of use data, as well as any other data which is acquired by the detector device. - View Dependent Claims (31)

33. A method for communicating data from a detector device comprising a single radio to a central server, the method comprising:
-
receiving, by the detector device, location data from one or more beacon over a first radio channel; switching, by the detector device, from the first radio channel to a second radio channel at a pre-set time interval; sending, by the detector device, data via the second radio channel to an access point, wherein the data is then sent to a central server; and switching, by the detector device, from the second radio channel to the first radio channel at a pre-set time interval. - View Dependent Claims (34, 35)
