Engineering Contradiction Analysis
1Reliability
If manual tuning is performed for communication frequency adjustments, then communication reliability is maintained, but time consumption and labor requirements increase significantly
Solution Approach 1:
The data driving device performs self-diagnosis and self-tuning by automatically detecting communication errors and adjusting its own communication frequency without external intervention. The control circuit monitors communication status and autonomously modifies operating parameters to resolve issues.
Solution Approach 2:
The system implements a feedback mechanism where the control circuit continuously monitors communication status between the data processing device and data driving device. When communication errors are detected, the system uses this feedback information to automatically adjust communication frequency and other parameters.
