Controller Redundancy Code Transmission for Data Speed
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data transmission systems face challenges in increasing speed while maintaining security, particularly in scenarios with long wired interconnects where higher transmission frequencies are not feasible, leading to a demand for alternative methods to enhance data transfer rates.
Innovation Solution
A device and controller configuration that generates a redundancy code using both first and second data, transmitting only the redundancy code with the first data, allowing the controller to anticipate the second data and determine the device's state without its transmission, thereby saving bandwidth and increasing transmission speed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If transmission frequency is increased to improve data transmission speed, then transmission speed is improved, but electromagnetic compatibility challenges worsen
Solution Approach 1:
The patent extracts only the essential data (first data) for transmission while leaving out redundant information (second data that can be anticipated by the controller). This reduces the amount of transmitted data without losing information, thereby increasing transmission speed without requiring higher frequencies that would cause EMC issues.
Solution Approach 2:
The controller performs preliminary action by anticipating and pre-computing the second data based on the expected device state. This allows the controller to prepare data locally without waiting for transmission, effectively reducing the transmission burden and improving overall system speed without increasing transmission frequency.
2Loss of information
If both first data and second data are transmitted together with redundancy code, then complete information is transmitted, but bandwidth consumption increases
Solution Approach 1:
The patent extracts and transmits only the first data along with the redundancy code, while excluding the second data from transmission. The controller compensates by generating the second data locally through anticipation, thus maintaining information completeness while significantly reducing bandwidth consumption.
Solution Approach 2:
Instead of transmitting the actual second data, the controller creates a copy or reconstruction of it by anticipating the device state. This copied data serves the same informational purpose as the original, reducing transmission requirements while maintaining data integrity.
3Speed
If second data is not transmitted to save bandwidth, then transmission speed increases, but device state monitoring capability deteriorates
Solution Approach 1:
The controller uses feedback mechanisms by continuously anticipating the device state based on received first data and system knowledge. This internal state estimation provides continuous monitoring capability without requiring explicit transmission of second data, thus maintaining monitoring precision while improving transmission speed.
Solution Approach 2:
The controller performs self-service by generating its own understanding of the device state through anticipation algorithms. Instead of relying on transmitted second data, the controller independently determines device state, maintaining monitoring capability while reducing transmission requirements.
