摘要： 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.

摘要： In an embodiment, an apparatus (e.g., a gas detection device) includes a housing, a printed circuit board (PCB), one or more radio modems with a switching network. The housing includes a conductive cover and the cover plays as an antenna. The PCB may be fixed in the housing and includes a ground plane and a plurality of conductive feeds. Each feed are vertically mounted directly or indirectly on the PCB. When the cover is attached to the housing, each of the feeds electrically contact a respective connection point on the antenna. The switching network is to configure which feed should be connected to the radio modem. A extra grounding resistor is mounted or not to change antenna type to enhance the performance of antenna.
