Sensor Terminal Metadata Collection via Communication Protocol Extension
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for collecting metadata from sensor terminals in IoT systems are costly, complex, and prone to human error, especially when associating sensing data with metadata, as they require dedicated systems or manual confirmation.
Innovation Solution
A system that utilizes an extended or optional area in communication protocols to collect and transmit metadata alongside sensing data, using a detection unit in sensor terminals to detect internal information and associate it with sensing data and equipment information within a data collection network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a dedicated system is developed to collect metadata from sensor terminals, then metadata collection capability is improved, but device complexity and cost increase
Solution Approach 1:
The patent applies universality by enabling the sensor terminal to use its existing communication protocol for dual purposes: transmitting both sensing data and metadata through the same protocol mechanism. The communication protocol's extended or optional area is utilized to carry metadata alongside sensing data, eliminating the need for a separate dedicated metadata collection system and reducing overall device complexity.
2Adaptability or versatility
If manual collection method is used to gather metadata, then collection flexibility is improved, but operational complexity and error rates increase
Solution Approach 1:
The patent implements self-service by having the sensor terminal automatically detect and transmit its own metadata information through its built-in detection unit. The terminal self-monitors its internal state (CPU usage, memory usage, voltage, temperature) and automatically incorporates this metadata into the communication protocol transmission, eliminating manual collection operations and associated errors while maintaining operational simplicity.
3Loss of information
If separate systems are developed for sensing data and metadata collection, then data specificity is improved, but cost and operational complexity increase
Solution Approach 1:
The patent applies merging by combining sensing data and metadata transmission into a single integrated communication process. The sensor terminal transmits both types of data together using the same communication protocol, with metadata placed in the extended or optional area. This unified approach maintains data specificity through structured separation while reducing system configuration complexity by eliminating the need for separate collection systems.
