Method and internet of things system for liquid accumulation supervision in smart gas pipelines

An Internet of Things system for liquid accumulation supervision in smart gas pipelines, comprising a gas company management platform, a gas company sensor network platform, and a gas device object platform, wherein

• the gas company management platform is configured to:
• obtain gas sampling information from a storage device in a gas gate station at an upstream of a gas pipeline, wherein the gas sampling information is obtained by a sampling device sampling at a gas valve;
• determine a cumulative transmission time based on a sampling time point automatically recorded and uploaded by a gas auxiliary facility;
• determine a liquid accumulation volume in an interior of the gas pipeline based on the gas sampling information and the cumulative transmission time, and mark the liquid accumulation volume at positions of different pipeline models in a Geographic Information System (GIS);
• and
• in response to determining that the liquid accumulation volume in the interior of the gas pipeline increases to a preset volume threshold, determine a valve opening adjustment amount and control a pressure regulating valve of the gas gate station to move based on the valve opening adjustment amount to reduce a valve opening, or issue an instruction to the gas gate station to replace a filter element of a gas filtration device so as to reduce a liquid accumulation generation rate in a gas pipeline downstream of the gas gate station;
• and remotely control a liquid accumulation supervision device to open an automatic blowdown valve to reduce the liquid accumulation volume in the gas pipeline.
