Methods for safety management of compressors in smart gas pipeline network and internet of things systems thereof

An Internet of Things system for safety management of a compressor in a smart gas pipeline network, wherein the Internet of Things system comprises:

• a smart gas safety management platform;
• and
• the smart gas safety management platform is configured to perform operations including:
• obtaining sound data and a target vibration feature of a gas compressor, and determining a target sound feature based on the sound data, including determining the target sound feature based on purifying the sound data;
• wherein a purifying process includes obtaining the target sound feature by processing the sound data using a purification model;
• obtaining gas data and device data, and determining a standard sound feature and a standard vibration feature based on the gas data and the device data;
• and
• predicting whether there is a safety hazard in the gas compressor based on the target vibration feature and the standard vibration feature, or based on the target sound feature and the standard sound feature, including predicting the safety hazard in the gas compressor by processing the target vibration feature and the standard vibration feature, or processing the target sound feature and the standard sound feature using a hazard model.
