Innovation Solution
An Internet of Things (IoT) system and method for managing energy-saving early warnings, involving a smart gas management platform that determines remaining power, confidence levels, and issues alerts based on calibrated power and operation data, generating an energy-saving management scheme.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If battery-powered smart gas flowmeters are used for gas metering, then the device can operate autonomously in pipeline networks, but the battery power depletes over time causing automatic valve closure and gas supply interruption
Solution Approach 1:
The system performs preliminary actions by continuously monitoring battery power levels and issuing early warnings before complete power depletion occurs. The management platform tracks power consumption trends and proactively notifies users to replace batteries, preventing the automatic valve closure that would interrupt gas supply.
2Measurement precision
If simple power monitoring is implemented, then the system can detect battery status, but inaccurate power assessment leads to premature battery discard or failure to warn
Solution Approach 1:
The system implements feedback mechanisms by continuously monitoring power consumption patterns and comparing them against expected values. The management platform receives power status data from flowmeters, analyzes consumption trends, and adjusts warnings based on actual usage patterns, thereby improving both detection accuracy and warning reliability.
Solution Approach 2:
The smart gas flowmeter performs self-diagnosis of its power status and automatically transmits power level information to the management platform. The system serves itself by monitoring its own battery health and triggering appropriate warnings without requiring manual intervention.
3Loss of time
If continuous power monitoring is performed, then timely warnings can be issued, but the system complexity and data processing requirements increase
Solution Approach 1:
The patent introduces a management platform as an intermediary between the smart gas flowmeters and users. This centralized platform handles the complex data processing, power consumption analysis, and warning generation, while the flowmeters themselves remain relatively simple devices that only need to transmit basic power status information.

AI summary
A method for managing energy-saving early warning of a smart gas flowmeter is provided. The method is executed by a smart gas management platform. The method comprises obtaining a remaining power of the smart gas flowmeter, determining a confidence level of the remaining power based on at least environmental data, determining a calibrated power by calibrating the remaining power based on the confidence level, determining 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. The reference correspondence represents a relationship between an operation behavior of the smart gas flowmeter and a power consumption. The method also comprises generating 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.
