Monitoring System Dual-Use Transmission Line for Interrupt Signals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing household appliance monitoring systems require additional data lines for fast and high-priority switching processes, increasing complexity and technical effort, and often complicate the device structure.
Innovation Solution
A monitoring system that uses a single standardized transmission line for both regular data transmission and event signaling by employing an electronic triggering arrangement to detect events and output interrupt requests, allowing the same line to transmit event signals independently of regular data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If additional data lines are used for interrupt signals, then fast and high-priority switching operation is enabled, but technical effort and installation space increase
Solution Approach 1:
The transmission line is designed to serve dual purposes: regular data transmission and event signal transmission. The same physical line carries both types of signals by utilizing different signal levels or states, eliminating the need for separate interrupt signal lines while maintaining fast response capability for exceptional cases
2Speed
If additional data lines are used for interrupt signals, then fast switching operation is enabled, but assembly complexity increases
Solution Approach 1:
By making the transmission line multi-functional, the number of connections to be assembled is reduced. The same line is connected to both data processing and event detection circuits, simplifying the assembly process while still enabling fast interrupt response when needed
3Ease of manufacture
If standardized interfaces are used for data transmission, then technical effort is reduced, but transmission speed for non-time-critical data is limited
Solution Approach 1:
The transmission system is segmented into two modes: regular data transmission using standardized interfaces for non-time-critical data, and event signal transmission for time-critical interrupt signals. This segmentation allows each mode to be optimized independently - standardized interfaces keep technical effort low while event signals provide fast response when needed
