Synchronized Position and Sensor Data Provision for Motor Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data provision systems face challenges in combining position data and additional data, such as vibration or temperature data, from different sensors with different measurement principles and sampling frequencies, leading to unclear relationships between the data sets, which complicates their use in motor control or regulation systems.
Innovation Solution
A data provision device with a signal processing unit that receives and combines position data and additional data, bringing them into a defined temporal or position-based relationship before transmission to a higher-level unit, ensuring synchronized and accurate data usage for control or regulation purposes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If position data and additional data are acquired independently with different sampling frequencies, then data acquisition flexibility is improved, but data synchronization and temporal relationship definition deteriorate
Solution Approach 1:
The patent applies preliminary action by introducing a trigger signal mechanism that pre-establishes the temporal relationship between position data and additional data acquisition. The trigger signal is generated based on position data and precedes the acquisition of additional data, ensuring that both data types are synchronized to the same reference point before being combined for transmission. This resolves the synchronization issue while preserving independent acquisition flexibility.
2Device complexity
If data from multiple acquisition devices are combined for joint transmission, then connection complexity at the higher-level unit is reduced, but data relationship clarity deteriorates
Solution Approach 1:
The patent introduces an intermediary data processing unit that receives both position data and additional data, establishes their temporal relationships using trigger signals, and combines them into a synchronized data package. This intermediary component maintains data relationship clarity while enabling joint transmission, thereby reducing connection complexity at the higher-level unit without losing information about data relationships.
3Productivity
If additional data are transmitted with time delay or in bulk, then transmission efficiency is improved, but real-time data accuracy deteriorates
Solution Approach 1:
The patent implements periodic action through a structured trigger signal mechanism that periodically synchronizes data acquisition and transmission. Rather than continuous transmission or delayed bulk transmission, the system uses periodic trigger signals based on position data to initiate additional data acquisition and transmission, achieving both transmission efficiency and real-time accuracy by transmitting data in synchronized periodic cycles.

AI summary
A data provision device for providing position data and additional data to a higher-level unit comprises a signal processing unit configured to receive position data and additional data, combine the position data and the additional data for joint data transmission, and then output them together. The data provision device further comprises a signal processing unit configured to receive position data from a position acquisition device and additional data from an additional data acquisition device, to establish a defined, preferably temporal, relationship to the position data, and then output at least the additional data to the signal processing unit.
