Transmission Control System Eye Pattern Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In high-speed transmission systems, such as those related to PCIe, it is difficult to appropriately monitor signs of failure and adjust transmission parameters during system operation, leading to potential deterioration in performance and redundancy.
Innovation Solution
A transmission control method and system that determine transmission performance using an 'internal eye value' parameter, which assesses the size of the eye pattern, and adjust transmission parameters to maintain or improve transmission quality, enabling effective failure monitoring and prevention of system performance degradation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If high-speed transmission is used to improve data transmission rate, then transmission speed increases, but transmission quality deteriorates due to cable breakage or deterioration
Solution Approach 1:
The system performs route diagnosis and measures eye pattern parameters before transmission failures occur, allowing preventive maintenance. The controller proactively monitors transmission line status using eye pattern opening size as an indicator, enabling early detection of cable deterioration or breakage before it affects high-speed data transmission quality
Solution Approach 2:
The system continuously measures eye pattern parameters during operation and uses this feedback to determine transmission line status. The controller adjusts or replaces cables based on the measured eye pattern opening size, creating a closed-loop feedback mechanism that maintains transmission quality while enabling high-speed data transfer
2Reliability
If route diagnosis is performed to improve transmission reliability, then transmission quality is monitored, but system operation is affected
Solution Approach 1:
The system performs eye pattern measurement and route diagnosis continuously during normal system operation without interruption. The controller measures transmission line status in the background while data transmission continues, ensuring both continuous monitoring and uninterrupted productivity. This allows the system to maintain reliability monitoring while preserving operational continuity

AI summary
A transmission control method includes: determining transmission performance in a transmission line by using a parameter that determines a size of an opening of an eye pattern; and adjusting a transmission parameter that is a parameter having an influence on transmission quality in the transmission line on the basis of a result of the determination.
