Solution Overview
Problem
Current gas leakage detection methods in home safety are prone to false and omitted judgments due to reliance on combustible gas alarms, leading to poor accuracy and potential safety hazards.
Innovation Solution
A compound IoT system comprising a user platform, management platform, sensor network sub-platforms, and service sub-platforms, including a gas meter, which sends detection commands, processes gas data, and sends valve closing instructions based on predefined thresholds and user queries to accurately detect and respond to gas leaks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional combustible gas alarms are used for gas leakage detection, then the detection mechanism is simple, but the accuracy of leakage detection is poor due to false judgments and omitted judgments
Solution Approach 1:
The system segments the gas detection function across multiple components: gas meter with flow sensors, smart valves, mobile application, and cloud platform. Each component performs a specific function (flow measurement, valve control, user interaction, data processing), collectively achieving high detection accuracy without requiring a single complex alarm device
Solution Approach 2:
The gas meter is designed to perform multiple functions: traditional gas consumption measurement, gas leakage detection through flow pattern analysis, and integration with smart valve control. This multi-functionality improves detection accuracy while avoiding the need for separate specialized alarm devices
2Reliability
If traditional alarms are installed far from gas leakage positions, then the installation flexibility is high, but omitted judgments occur reducing detection reliability
Solution Approach 1:
The system introduces mobile devices and cloud communication as intermediaries between the gas meter and the user. The gas meter continuously monitors flow data and can remotely control smart valves, eliminating the need for physical proximity between alarm and leakage source while maintaining high reliability through automated detection and response
3Reliability
If continuous monitoring is implemented to improve detection accuracy, then the reliability increases, but the energy consumption increases
Solution Approach 1:
The system implements periodic flow data collection and analysis instead of continuous high-power transmission. The gas meter monitors flow continuously at low power, transmits data periodically to the cloud platform for analysis, and only activates high-power components when anomalies are detected, maintaining reliability while reducing energy consumption
