ATC Intermittent Data Processing Using Dual Buffer Merging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ATC intermittent information processing systems face challenges in accurately analyzing signals at high speeds due to decreased message reception, leading to potential frame loss and data corruption from noise.
Innovation Solution
A method and apparatus that utilize dual buffers to store and combine data from left and right loops, aligning start-notifying data with information data, and transmitting final combined data to on-board equipment, while managing buffer clearing and waiting for complete frames to minimize frame loss and noise-induced errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the train operates at high speed, then productivity is improved, but the message reception accuracy deteriorates due to decreased message reception
Solution Approach 1:
The patent combines data from multiple buffers (first buffer, second buffer, third buffer) to form complete frames. By merging partial frame data received at different times into a complete frame, the system maintains measurement precision even when message reception is reduced at high speeds.
Solution Approach 2:
The patent stores incoming data in buffers before complete frames are assembled. This preliminary storage action allows the system to accumulate data segments and reconstruct complete frames even when reception timing is compressed due to high speed operation, thereby preserving accuracy.
2Productivity
If the train operates at high speed, then productivity is improved, but frame loss increases due to decreased message reception
Solution Approach 1:
The patent merges partial frame data from multiple buffers to reconstruct complete frames. This combining approach reduces frame loss by ensuring that even if some messages are missed at high speeds, the complete frame can still be assembled from accumulated buffer data.
Solution Approach 2:
The patent uses buffers to cushion and store incoming data before frame assembly is complete. This beforehand cushioning creates a buffer zone that protects against frame loss during high-speed operation when message reception may be incomplete or timing-critical.
3Productivity
If data is continuously received at high speed, then productivity is improved, but data corruption from noise increases
Solution Approach 1:
The patent segments incoming data into distinct frames with clear start and end markers. By dividing the continuous data stream into discrete, manageable frames, the system can process and validate each frame independently, reducing the impact of noise corruption on the overall data reception.
Solution Approach 2:
The patent uses start-notifying data and frame assembly feedback to verify successful reception and assembly of complete frames. This feedback mechanism allows the system to detect and handle noisy or corrupted data segments, ensuring data integrity even during high-speed reception.
