Methods and internet of things systems for monitoring the reliability of self-closing valves for smart gas

An Internet of Things (IoT) system for monitoring a reliability of a self-closing valve for smart gas, wherein the IoT system comprises a smart gas user platform, a smart gas service platform, a smart gas equipment management platform, a smart gas sensing network platform, and a smart gas object platform interacting in sequence;

• the smart gas equipment management platform being configured to:
• obtain, in response to the gas self-closing valve being closed, operating environment data in a first preset time and gas usage information of a gas user in the first preset time;
• determine a closure type of the gas self-closing valve based on the gas usage information and a setting position of the gas self-closing valve, the closure type including a first type and a second type, the first type being related to a gas usage situation, and the second type being related to a gas supply situation;
• in response to the closure type being the first type, issue an adjustment prompt;
• and
• in response to the closure type being the second type, determine a reliability of a current closure state of the gas self-closing valve based at least on the operating environment data, and determine whether to issue an alert prompt based on the reliability.
