Installed Gases
Project Details
Hello from Raymond Korea. Metro and highway tunnels are regulated confined spaces where early construction phases have no mobile coverage. Reliable gas detection with rapid uplink is still mandatory.
System outline: (1) Detect gases from blasting or welding inside the heading. (2) Send readings over cable to a wireless AP. (3) The AP forwards data to a server so phones or PCs can monitor remotely.
Field transmitters only need power plus a short data homerun to the shared router.
Each heading continuously tracks O2, CO, H2S, and combustibles (LEL) with local audible/visual alarms.
LAN infrastructure and a hardened router must exist before we commission gas nodes. Multiple detectors home-run to one AP.
Where Wi-Fi already penetrates the tunnel, you can skip the external AP and assign IPs directly. You must still host a data sink (server or SCADA) and route alarms to phones or a control room. Thank you for reading.
