Sensor Unit Synchronization via Network Signal Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing synchronization measurement systems require multiple sub-controllers to synchronize all sensor units, making it difficult to construct a compact system.
Innovation Solution
A synchronization measurement system where a single controller sets sensor units as nodes to transmit synchronous signals and measurement data over networks, eliminating the need for dedicated devices and allowing for synchronization across multiple networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple sub-controllers are used to synchronize all sensor units, then synchronization capability is improved, but device complexity and system size increase
Solution Approach 1:
The sensor units are designed to perform multiple functions: they can both perform measurements and transmit synchronous signals. By enabling sensor units to function as both measurement devices and synchronization signal transmitters, the system eliminates the need for dedicated sub-controllers, thereby reducing device complexity while maintaining synchronization capability.
Solution Approach 2:
The sensor units serve themselves by autonomously transmitting synchronous signals to other sensor units. Instead of requiring external sub-controllers to manage synchronization, the sensor units self-organize and self-synchronize through peer-to-peer communication, reducing the overall system complexity.
2Measurement precision
If multiple sub-controllers are deployed to achieve comprehensive synchronization, then measurement coverage is improved, but storage capacity requirements increase
Solution Approach 1:
The synchronous signal is transmitted and reused across multiple sensor units through the network. Instead of each sub-controller storing and managing separate synchronization data, the same synchronous signal is copied and propagated through the network to all relevant sensor units, reducing overall storage requirements while maintaining synchronization accuracy.
3Reliability
If dedicated synchronous signal transmission devices are added, then signal transmission reliability is improved, but system compactness deteriorates
Solution Approach 1:
The sensor units are designed to perform multiple functions: they can both perform measurements and transmit synchronous signals. By enabling sensor units to function as both measurement devices and synchronization signal transmitters, the system eliminates the need for dedicated sub-controllers, thereby reducing device complexity while maintaining synchronization capability.
Solution Approach 2:
The functions of measurement and synchronous signal transmission are merged into the same sensor units. This consolidation eliminates the need for separate dedicated transmission devices, making the system more compact while maintaining reliable signal transmission through the existing sensor unit infrastructure.
