Aircraft Telemetry Visualization With Parallel Display and Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current telemetry visualization systems introduce delays and potential failures by requiring telemetry data to be stored persistently before it can be displayed, which can lead to slow data reception and RE response during critical testing phases, increasing the risk of significant failures.
Innovation Solution
A telemetry visualization system that minimizes software interactions by using concurrent and parallel processing to deliver telemetry data directly to control room displays while storing a copy in persistent storage, allowing immediate display and redundancy in case of storage failures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If telemetry data is written to persistent storage before display, then data redundancy and reliability are improved, but data display delay and system response time increase
Solution Approach 1:
The system segments the data flow into two independent parallel paths: one path writes telemetry data to persistent storage for reliability, while the other path streams data directly to display terminals for immediate visualization. This segmentation allows both storage reliability and display speed to be optimized independently without sequential dependency.
Solution Approach 2:
The system introduces an intermediary buffering mechanism that decouples the persistent storage write operations from the display read operations. The buffer acts as a mediator that can supply data to displays while the storage system processes writes at its own pace, eliminating the wait time that would otherwise be required for storage completion before display.
2Reliability
If telemetry data is stored persistently before display, then data loss prevention is improved, but system complexity and potential failure points increase
Solution Approach 1:
The system creates a copy of the telemetry data stream that is sent directly to display terminals, while the original stream continues to persistent storage. This copying approach provides data redundancy for loss prevention without requiring complex transformations or additional processing components, simply duplicating the data flow path.
3Reliability
If all telemetry data must be stored before display, then data integrity is improved, but RE response time to non-nominal conditions deteriorates
Solution Approach 1:
The system performs preliminary action by pre-streaming telemetry data to display terminals before persistent storage operations are complete. This allows Responsible Engineers to see and respond to non-nominal conditions immediately, while the data integrity requirement is still satisfied through the concurrent persistent storage operation.

AI summary
Systems, methods and computer-readable media for telemetry data visualization are described herein. The described system includes paths and reduced components in between reception of sensor data and display to an engineer, reducing time delays and reducing the possibilities of scenarios where telemetry does not reach the responsible engineer to monitor and respond to various situations that may arise. In particular embodiments, a communications hub allows telemetry sensor readings to be simultaneously consumed by multiple components in memory-optimized fashion.
