Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In electromagnetic compatibility testing, there is a gap between real-time monitoring video and test data display, leading to inaccurate detection results due to asynchronous recording and observation.
Innovation Solution
An electromagnetic compatibility testing system and method that synchronously displays test data and video on-screen by using a testing unit, data acquiring unit, camera monitoring unit, and on-screen display controlling unit, where the data acquiring unit extracts target data from test data and sends it to the on-screen display controlling unit for simultaneous display with video data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If test data is recorded separately from monitoring video, then data recording is possible, but time synchronization between video and data is lost
Solution Approach 1:
The patent merges test data and monitoring video into a single synchronized display on one screen. The test data is extracted from the testing unit and combined with video data from the camera monitoring unit, both displayed simultaneously by the on-screen display controlling unit. This eliminates the time delay between separate recording and viewing, allowing operators to see both video and corresponding test data in real-time without manual synchronization.
2Measurement precision
If test data is displayed in real-time with video, then accurate detection results are achieved, but system complexity increases
Solution Approach 1:
The patent introduces a data acquiring unit as an intermediary component that extracts test data from the testing unit and prepares it for display. This intermediary layer handles the data processing and synchronization tasks, separating the complexity from the main testing and monitoring functions. The data acquiring unit acts as a bridge between the testing unit and the on-screen display controlling unit, managing the integration without complicating the core testing operations.
3Productivity
If separate monitoring and testing operations are used, then operational flexibility is maintained, but time delay between video and data occurs
Solution Approach 1:
The patent implements continuous synchronized display of both monitoring video and test data through the on-screen display controlling unit. Instead of intermittent separate viewing, the system maintains continuous real-time display of both data streams simultaneously. This eliminates gaps and delays between video observation and data recording, allowing operators to continuously correlate visual observations with corresponding test measurements without time loss.
