Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In redundancy control systems, existing methods fail to accurately detect errors in computational data transmitted from redundant processing devices, leading to incorrect data recognition and inability to distinguish between verified and unverified data, especially when one processing device fails.
Innovation Solution
A redundancy control system that employs two processing devices generating data using different algorithms, comparing and verifying the data, and transmitting signature data for authentication, allowing error detection and fault diagnosis at the receiving end.

Engineering Contradiction Analysis
1Measurement precision
If CRC computation device is used for error detection in transmitted data, then transmission errors can be detected at receiving end, but inability to confirm correctness of computational data generated by redundant processing devices
Solution Approach 1:
The patent introduces an intermediary verification mechanism where the receiving end uses stored generation algorithms to independently verify the computational data. This intermediary verification process bridges the gap between simple CRC error detection and comprehensive processing device correctness confirmation, allowing the system to detect both transmission errors and processing device failures without requiring direct communication between processing devices.
2Reliability
If redundant processing devices are used to generate computational data, then system reliability is improved, but inability to detect failure of processing devices when one system fails
Solution Approach 1:
The patent implements a feedback mechanism where the receiving end verifies the computational data by regenerating it using stored algorithms and comparing it with the received data. This feedback loop provides continuous monitoring of processing device correctness, enabling detection of processing device failures while maintaining system redundancy. The verification result feeds back to confirm whether the redundant processing devices are functioning correctly.
3Speed
If computational data is transmitted directly from processing device without verification, then transmission speed is maintained, but erroneous data may be wrongly recognized as correct
Solution Approach 1:
The patent applies preliminary action by having the receiving end prepare and store the generation algorithms in advance, so that verification can be performed immediately upon data receipt without delaying transmission. This preliminary preparation enables fast verification that maintains transmission speed while ensuring data correctness through algorithm-based validation of computational data.
