Solution Overview
Problem
Modern electronic device testing, especially for communication devices, requires synchronization of multiple devices during automated test scenarios, where existing technologies lack an efficient method to generate and manage control command sequences for correct device operation.
Innovation Solution
A command recording arrangement and method that utilize a data interface and command processor to merge control commands from multiple devices based on timestamps, ensuring correct sequencing and device identification for synchronized operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If manual control of multiple devices is used in test scenarios, then device operation flexibility is maintained, but automation capability and efficiency are insufficient
Solution Approach 1:
The system records manual user inputs and device responses as command sequences, creating a reusable digital copy of the operational procedure. This recorded sequence can then be automatically executed multiple times without manual intervention, achieving automation while preserving the original operational logic
Solution Approach 2:
The system enables self-service automation by recording the operator's own manual operations and allowing them to be automatically replayed. The recorded command sequences serve the system itself, eliminating the need for separate automated control mechanisms while achieving operational automation
2Reliability
If control commands for multiple devices are managed separately, then device independence is maintained, but synchronization accuracy deteriorates
Solution Approach 1:
The system merges control commands from multiple independent devices into a unified chronological sequence based on timestamps. This consolidation maintains the independence of individual device commands while achieving synchronized execution through centralized temporal ordering, resolving the contradiction between device independence and synchronization accuracy
Solution Approach 2:
The command recording system acts as an intermediary that receives commands from multiple devices, timestamps them, and reorders them chronologically. This intermediary layer协调s the independent device commands without requiring direct device-to-device communication, achieving synchronization while preserving device independence
3Productivity
If automated test scenarios are implemented without proper command sequencing, then test efficiency increases, but test accuracy and reliability decrease
Solution Approach 1:
The system performs preliminary recording of the correct command sequence and timestamp ordering before automated execution. By pre-establishing the accurate chronological sequence of operations during the recording phase, the system ensures that automated execution follows the proven correct procedure, maintaining test accuracy while achieving efficiency through automation
Solution Approach 2:
The system incorporates feedback mechanisms where device responses are recorded and timestamped alongside commands. This feedback loop allows verification that commands were executed in the correct sequence and enables detection of any deviations, ensuring test reliability while maintaining automated efficiency

AI summary
Recording of a control command sequence related to multiple devices. Each of the multiple devices may receive user input by a user inter-face, and the received user input may be converted to appropriate control commands. Timestamp information is assigned to each control command, and the control commands of the multiple devices are merged together to a common control command sequence based on the assigned timestamp information.
