Methods, internet of things systems, and storage medium for managing energy- saving early warning of smart gas flowmeters

An Internet of Things system for managing energy-saving early warning of a smart gas flowmeter, comprising:

• a smart gas user platform, a smart gas service platform, a smart gas management platform, a smart gas sensor network platform, and a smart gas object platform interacting in sequence, wherein the smart gas management platform is configured to:
• obtain a remaining power of the smart gas flowmeter;
• determine a confidence level of the remaining power based on at least environmental data;
• determine a calibrated power by calibrating the remaining power based on the confidence level;
• determine whether to issue a power alert to a gas user based on the calibrated power, operation data of the smart gas flowmeter, and at least one reference correspondence, wherein to determine whether to issue the power alert to the gas user based on the calibrated power, the operation data of the smart gas flowmeter, and the at least one reference correspondence, the smart gas management platform is further configured to:
• preset the at least one reference correspondence based on at least historical aggregate operation data of the smart gas flowmeter, wherein the reference correspondence represents a relationship between an operation behavior of the smart gas flowmeter and a power consumption;
• determine a battery reference runtime of the smart gas flowmeter based on the calibrated power, the operation data, and the at least one reference correspondence;
• and
• issue the power alert to the gas user in response to a determination that the battery reference runtime is less than a time threshold;
• and
• generate an energy-saving management and operation scheme of the smart gas flowmeter in response to a determination that the power alert is issued to the gas user.
