Synchronized Measurement Display Windows for ECU Signal Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicular measurement data display systems struggle to synchronize multiple signal groups effectively, leading to inefficiencies in test function division and mutual influence between display windows.
Innovation Solution
Implement a synchronization identifier and function for multiple measurement data display windows, allowing synchronized display by matching identifiers when a paused window's time span is modified, enabling synchronized display across different windows.

1Object-affected harmful factors
If multiple measurement data display windows are used to display different signal groups, then the signals can be grouped and displayed separately without mutual influence, but the synchronization of display time spans across windows becomes complex and difficult to manage
Solution Approach 1:
The system segments the measurement data display into multiple independent windows, each displaying a specific signal group (e.g., power assembly, chassis electric control). Each window is assigned a unique synchronization identifier, allowing independent management while maintaining overall synchronization through the identifier-based matching mechanism.
Solution Approach 2:
The synchronization identifier acts as an intermediary element that mediates between multiple display windows. When one window's time span is modified, the system uses the identifier to call the synchronization function of other windows with matching identifiers, enabling coordinated updates without direct complex inter-window dependencies.
2Measurement precision
If manual repositioning is required when switching between graphical and packet information windows, then display precision can be maintained, but analysis efficiency decreases due to additional manual operations
Solution Approach 1:
The display windows automatically synchronize their time spans through the synchronization function. When one window's time span is modified, other windows with matching synchronization identifiers automatically update their display ranges without requiring manual intervention, thereby maintaining precision while improving analysis efficiency.
Solution Approach 2:
The system implements a feedback mechanism where modification of one window's time span triggers a synchronization response in other windows. The synchronization function monitors changes and automatically adjusts other windows to match the modified time span, ensuring consistent display precision across all windows.
3Ease of operation
If synchronization function is implemented for all display windows, then synchronized viewing is enabled, but the system complexity and computational overhead increase
Solution Approach 1:
The synchronization function is selectively applied based on synchronization identifiers. Not all windows need to synchronize with all other windows; instead, windows are grouped by identifier, and the synchronization function is activated only for windows sharing the same identifier, reducing unnecessary computational overhead while maintaining synchronized viewing capability where needed.
