Synchronous Data Transmission Event Notification Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In synchronous data transmission systems, critical events at the transmitter, such as a sudden loss of power, require immediate notification to the receiver to prevent data loss or corruption, but serial data processing and transmission delays the notification, and interrupts regular data transmission.
Innovation Solution
A data transmission system with an event monitor, an adjustable clock signal producer, and an event recognition system that transmits event-specific clock signals to immediately notify the receiver of critical events without interrupting regular data transmission, allowing for immediate action and prioritization of events based on relevance.

Engineering Contradiction Analysis
1Reliability
If data is transmitted serially in synchronous data transmission systems, then data transmission follows a standardized protocol, but critical event information experiences delay and regular data transmission is interrupted
Solution Approach 1:
The transmission system segments information into two distinct channels: regular data transmission follows the standard synchronous protocol, while critical event information is transmitted through a separate interrupt mechanism. This segmentation allows event notifications to bypass the serial data transmission queue, eliminating delay without disrupting regular data flow.
Solution Approach 2:
An interrupt signal acts as an intermediary between the transmitter and receiver for critical events. When a critical event occurs, this intermediary signal immediately notifies the receiver, bypassing the normal serial data transmission path. This mediator enables rapid event notification while preserving the integrity and continuity of regular synchronous data transmission.
2Loss of time
If critical event information is transmitted immediately, then response time is reduced, but regular data transmission is interrupted
Solution Approach 1:
The system separates critical event transmission from regular data transmission into distinct channels. Critical events use an interrupt-based immediate notification channel, while regular data continues through the synchronous transmission channel. This segmentation ensures that immediate event notification does not interrupt or reduce regular data transmission productivity.
Solution Approach 2:
The interrupt mechanism for critical events is designed to operate independently and simultaneously with regular synchronous data transmission. The useful action of regular data transmission continues uninterrupted while the interrupt system provides continuous monitoring and immediate notification of critical events, maintaining both productivity and rapid response capability.
3Device complexity
If serial data processing is used, then data transmission is simplified, but valuable time is lost before critical event data can be transmitted
Solution Approach 1:
An interrupt signal serves as a simple intermediary mechanism that adds minimal complexity to the system. When a critical event occurs, this intermediary immediately triggers event data transmission, bypassing the need for complex prioritization or queue management. This simple interrupt mechanism significantly reduces event notification delay while maintaining overall system simplicity.
Solution Approach 2:
The system changes the transmission parameter from standard synchronous mode to interrupt-driven mode when critical events occur. This parameter change allows the system to switch between normal operational mode and emergency notification mode, enabling rapid event transmission without permanently increasing system complexity. The interrupt mechanism remains dormant during normal operation, adding no complexity until needed.

AI summary
A synchronous data transmission system for transmission of data between two communication partners, of which one serves as a transmitter and one as a receiver, comprising a clock signal producer which produces a transmission clock signal with a transmission clock signal rate from the transmitter to the receiver, which during the occurrence of one of the events equals an event specific transmission clock signal rate associated with the arising event and during an event free period of time equals a fundamental clock rate different of all event specific transmission clock signal rates.
