Signal Recording Timing Control for Accurate Target Signal Acquisition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems face challenges in accurately acquiring a target signal from time series signals output by devices like sensors and motors, as the accuracy of subsequent processing can be affected by the timing of signal acquisition.
Innovation Solution
A control apparatus and method that includes a first acquisition part, a recording part, and a determination part, where the determination part determines the timing for recording the first signal based on preset conditions, potentially using a second signal from a different device to ensure accurate acquisition of the target signal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If signal acquisition timing is not optimized, then processing accuracy may deteriorate, but system complexity increases when implementing timing determination mechanisms
Solution Approach 1:
The determination part pre-establishes recording timing conditions and thresholds before signal acquisition begins. By determining the timing criteria in advance rather than calculating it in real-time during acquisition, the system achieves precise signal timing selection without adding complex real-time computation mechanisms.
Solution Approach 2:
The signal recording system uses its own internal timing determination logic to automatically select optimal acquisition moments based on preset conditions. The determination part monitors the time series signal and autonomously decides when to trigger recording, eliminating the need for external timing control devices.
2Measurement precision
If multiple signals from different devices are integrated for timing determination, then signal acquisition accuracy improves, but device complexity and processing load increase
Solution Approach 1:
The determination part serves as an intermediary that receives time series signals from the first device and reference signals from the second device, then processes their relationship to determine optimal recording timing. This intermediary structure allows multiple devices to be integrated without requiring direct complex interactions between them.
Solution Approach 2:
The determination part is designed to handle multiple signal sources and various timing determination methods (threshold-based, event-based, or combination approaches) through a single unified mechanism. This multi-functional design allows the system to adapt to different signal types and timing criteria without requiring separate processing paths for each device.

AI summary
In the embodiments of the disclosure, a target signal which is a signal of a part used for subsequent processing is acquired from signals output from a device with higher accuracy. A control apparatus (3) includes a first acquisition part (31) which acquires a first signal of a time series output from a first device, a recording part (371) which records a part of the first signal acquired by the first acquisition part (31), and a determination part (373) which determines a timing at which the recording part (371) records the first signal based on a preset predetermined condition.
