1. An Internet of things (IoT) system for pipeline valve calibration based on smart gas safety supervision, comprising a smart gas government safety supervision management platform, a smart gas government safety supervision sensor network platform, a smart gas government safety supervision object platform, a gas company management platform, a gas company sensor network platform, a gas equipment object platform, and a gas equipment maintenance object platform; wherein
the smart gas government safety supervision management platform is configured to generate a first calibration instruction and send the first calibration instruction to the gas company management platform;
the gas company management platform is configured to:
in response to determining that the first calibration instruction is received, or historical calibration times of gas pipelines exceeding a calibration time threshold is monitored, perform a first calibration on the gas pipelines and pipeline valves on the gas pipelines to determine a first calibration result;
determine a flexible calibration batch based on sensing parameters and operation parameters;
generate, based on the flexible calibration batch and the first calibration instruction, a second calibration instruction, and perform a second calibration on the gas pipelines and the pipeline valves on the gas pipelines to obtain a second calibration result;
determine valves pending maintenance of the gas pipelines based on the first calibration result and the second calibration result; wherein
the valves pending maintenance includes a first alternative valve and a third alternative valve, the third alternative valve is a second alternative valve of which a maintenance order satisfies a preset sorting condition, a maintenance priority of the first alternative valve is higher that a maintenance priority of the second alternative valve; the gas company management platform is further configured to:
determine the first alternative valve based on a feedback result of the smart gas government safety supervision management platform, the first alternative valve including the valve pending maintenance which has a fault based on feedback from a gas user;
determine the second alternative valve based on the first calibration result, the second calibration result, and the first alternative valve;
determine a maintenance order of the second alternative valve based on the first calibration result and the second calibration result;
determine the third alternative valve based on the maintenance order of the second alternative valve;
determine the valves pending maintenance based on the third alternative valve and the first alternative valve;
determine work order information based on the valves pending maintenance;
determine a work order dispatch instruction based on the work order information and send the work order dispatch instruction to the gas equipment maintenance object platform; and
generate, prior to maintaining the valves pending maintenance, a parameter adjustment instruction and adjust a working parameter of an auxiliary device operating in cooperation with the valves pending maintenance based on the parameter adjustment instruction.
