Remote Device Circuit Allocation Using Power-Supply Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In multi-power supply systems with remotely located devices, installation errors often occur due to the mismatch between power supply units and devices, leading to improper power characteristics, which is difficult to rectify manually, especially in distant locations.
Innovation Solution
An automated method using signal information feedback loops between centralized power supply units and remote devices to automatically allocate DC power supplies based on power requirements, enabling precise matching and correcting installation errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual checking of continuity or switching power supply outputs on and off is used to verify proper allocation, then installation errors can be detected, but the procedure becomes complicated and time-consuming especially when remote devices are distant from each other
Solution Approach 1:
The system enables automatic self-identification of remote devices through signal transmission and feedback. Each remote device automatically responds to identification signals, allowing the controller to autonomously detect and verify connections without manual intervention, thus resolving the contradiction between reliability and procedural complexity
Solution Approach 2:
The system implements feedback loops where remote devices transmit response signals back to the controller indicating their identification and connection status. This automated feedback mechanism replaces complex manual checking procedures while ensuring reliable allocation verification
2Adaptability or versatility
If multiple power supply units are used to meet different power requirements of remote devices, then power characteristics can be matched to device requirements, but installation errors may occur leading to mismatched allocation
Solution Approach 1:
The system performs preliminary identification and allocation of remote devices to power supply units before actual power delivery begins. The controller sends identification signals and receives responses to pre-establish the correct mapping between power supply units and devices, preventing mismatched allocation
Solution Approach 2:
Remote devices transmit feedback signals containing their identification information in response to controller signals. This feedback enables the controller to accurately determine which device is connected to which power supply unit, ensuring reliable correspondence despite the complexity of multiple power supply configurations

AI summary
A power transmission system is disclosed comprising a centralized power supply system having multiple DC power supply units and a controller coupled to the DC power supplies. Remote devices are coupled to the centralized power system via a power cable. In some embodiments, the DC power supply units transmit signal information to respective ones of the remote devices, and the remote devices may be configured to forward the signal information to the controller. In some embodiments, the controller module automatically allocates individual ones of the DC power supply units to the respective ones of the remote devices based on the forwarded signal information.
