Fault Information Transfer Using Local Storage and Notification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing transmission systems face inefficiencies in determining fault causes due to limitations in the transmission mechanism between devices, leading to prolonged times in obtaining fault information, which hampers the fault determining efficiency of processing units.
Innovation Solution
A fault information transmission method where the first device sends fault information to a second device, which stores it and sends a notification signal to the processing unit, allowing direct access to the fault information, thereby bypassing the inefficiencies of conventional transmission mechanisms and improving fault determining efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the B-end device determines fault by reading fault cause from A-end device register through transmission mechanism, then fault cause can be obtained, but fault determining efficiency is reduced due to transmission mechanism limitations
Solution Approach 1:
The patent applies preliminary action by pre-storing fault cause information in a local register at the B-end device before actual fault occurrence. When a fault happens, the processing unit can immediately read the pre-stored fault cause information without needing to transmit data across devices, thus resolving the contradiction between obtaining accurate fault cause information and maintaining high fault determining efficiency
Solution Approach 2:
The patent extracts the fault cause information from the A-end device and stores it locally in the B-end device's register. This extraction allows the B-end processing unit to access fault information directly from local storage rather than through the limiting transmission mechanism, thereby improving fault determining efficiency while maintaining measurement precision
2Loss of information
If fault information is transmitted from first device to second device through conventional transmission mechanism, then fault information can be conveyed, but time for obtaining fault cause is prolonged
Solution Approach 1:
The patent implements preliminary action by pre-transmitting and storing fault cause information in the second device's register before actual fault occurrence. This way, when a fault happens, the processing unit can immediately read the pre-stored information without waiting for transmission, thus reducing fault information acquisition time while ensuring information completeness
Solution Approach 2:
The patent uses a local register at the second device as an intermediary to store fault cause information. This intermediary storage mechanism eliminates the need for real-time transmission during fault events, allowing immediate access to complete fault information without time delay

AI summary
A fault information transmission method applied to a system including a first device and a second device In the fault information transmission method, when a fault occurs in a first transmission unit of the first device, the first device sends fault information to the second device, where the fault information indicates a fault cause of the first transmission unit; a second transmission unit of the second device receives the fault information, stores the fault information in a storage space, and sends a notification signal to a processing unit of the second device; and the processing unit receives the notification signal, and reads the fault information in the storage space.
