Conference System Connection State Management via Counter Flags
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional conference systems lack a reliable method to manage connection abnormalities, such as malfunctions or disconnections, which disrupt the continuous management of user and audio information across discussion units.
Innovation Solution
The conference system employs a control unit and discussion units connected via a communication line, using a running packet with a counter flag to monitor and manage connection states, allowing for continuous information acquisition even during connection abnormalities by comparing count values and updating storage records.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional conference systems are used without connection abnormality detection functions, then the system structure remains simple, but the reliability of connection state management deteriorates
Solution Approach 1:
The patent implements a feedback mechanism where the control unit transmits running packets with counter flags to discussion units, which return the packets with incremented count values. The control unit compares the returned count values with stored values to detect connection abnormalities. This continuous feedback loop enables reliable connection state management through automated monitoring and comparison operations.
Solution Approach 2:
The discussion units autonomously increment the counter flag count values and return them to the control unit without requiring manual intervention. The system self-monitors connection states by automatically comparing count values and detecting abnormalities, enabling reliable connection management through self-service operations.
2Measurement precision
If no counter flag mechanism is implemented, then the communication protocol remains simple, but the measurement precision of connection state detection deteriorates
Solution Approach 1:
The patent replaces manual connection verification with an automated counter flag mechanism. Instead of mechanical or manual checking methods, the system uses digital counter flags embedded in running packets to automatically track and detect connection states, achieving precise abnormality detection through digital comparison operations.
