Pressure, methane and leakage transmitters report over the network within seconds, and alarms push to the duty engineer. Edge thresholds and reporting rates are set per site.
A gas distribution network where pressure and leakage have to be watched together. Combustible-gas sensors and pressure transmitters read the pipeline, and the edge gateway reports the values upward within seconds.
Modbus RTU and TCP equipment from earlier upgrades joins the same gateway, thresholds and reporting rates are set per site, and alarms are pushed straight to the administrator. Terminals are explosion-proof and rated IP67, and the installation follows GB 50028.
Challenges
What the site has to get past before the readings are worth anything.
Leaks stay invisible
A small leak in a buried or ageing pipe is found only when someone smells gas or pressure drops.
Mixed legacy devices
Modbus RTU and TCP equipment from different vintages shares a network but rarely reports upward.
Fixed patrol routes
Manual inspection covers set routes, so the gap between checks is long and uneven.
System Architecture
Three layers: what is measured, how it travels, and where the rules and alarms live.
WE-X280 — Edge and uplinkWE-T800 — Node aggregation
Platform and reporting
WES device management platform — Alarms and notifications
