High Speed Data Transmission Error Detection via KILL Signal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High-speed network interface cards often fail to detect errors in data packets, which can lead to critical system failures in high-integrity applications like aircraft operations, where accurate data transmission is paramount.
Innovation Solution
A data transmission system with a monitoring module and external pull-up/pull-down resistors that detects errors and forces the data into an error state using a KILL signal, ensuring errors are identifiable by the receiver through cyclic redundancy checks or protocol checks.

1Speed
If high speed data transmission is implemented, then transmission speed is improved, but error detection capability deteriorates
Solution Approach 1:
The patent introduces an intermediary monitoring module that sits between the high-speed data transmission interface and the processing system. This module actively monitors incoming data packets for errors without impeding the high-speed transmission flow, thereby maintaining both speed and reliability. The intermediary captures error information and triggers appropriate error handling procedures.
Solution Approach 2:
The system implements preliminary error detection mechanisms that proactively identify potential errors before they can cause system failures. By continuously monitoring data integrity and detecting errors in advance, the system can take corrective actions such as requesting retransmission or isolating faulty data packets, thus preventing the propagation of erroneous data in high-speed transmission environments.
2Reliability
If error monitoring is enhanced, then data integrity is improved, but system complexity increases
Solution Approach 1:
The monitoring module is designed to autonomously detect errors and manage error handling without requiring complex external control systems. It self-configures monitoring parameters, automatically identifies error patterns, and triggers appropriate error responses independently, thereby maintaining data integrity while minimizing the complexity burden on the overall system architecture.
Solution Approach 2:
The patent combines multiple error detection functions into a single integrated monitoring module that handles various types of errors (data errors, control errors, protocol violations) through unified error handling logic. This consolidation approach improves data integrity across multiple functions while reducing the overall system complexity by eliminating redundant monitoring mechanisms.

AI summary
Systems and methods are described for reliably transmitting data in a network. The method includes: performing by a module, monitoring data from an output drive module for errors; and when an error is detected, generating a first signal based on the monitoring, and adjusting an input voltage to at least one of a pull-up resistor and a pull-down resistor for a predetermined time based on the first signal, to emphasize the error.
