Solution Overview

Problem

In multi-power supply systems with remote devices, installation errors often occur due to the remote location of devices, leading to improper power supply allocation, which can be complicated to rectify manually, especially when devices are distant from each other.

Innovation Solution

An automated method using signal information feedback between centralized power supply units and remote devices for automatic circuit allocation, where the controller identifies and corrects mismatches by modifying power characteristics based on received signal information.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If manual checking of continuity or switching power supply outputs is used to verify proper allocation, then allocation accuracy is improved, but installation complexity and time consumption increase significantly

Engineering Contradiction:

Improveallocation accuracyVSAvoidinstallation complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The system performs self-identification where each remote device automatically transmits its identity code through the power line, and the controller automatically matches devices with power supply units based on received signals, eliminating the need for manual continuity checking or switching operations

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system uses feedback signals transmitted from remote devices through the power lines to the controller, which then automatically adjusts power supply allocation based on the received identity codes and connectivity information

Inventive Principle:

Principle #23Feedback

2Reliability

If manual checking procedures are implemented to ensure proper power supply allocation, then allocation reliability is improved, but installation time increases

Engineering Contradiction:

Improveallocation reliabilityVSAvoidinstallation time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The system performs preliminary automatic identification and allocation during the initialization phase by transmitting identity codes and detecting connectivity through power lines, ensuring reliable allocation before full operation begins, eliminating the need for time-consuming manual verification during installation

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent replaces manual mechanical checking procedures with electronic signal transmission and automated controller logic, substituting human-operated continuity testers and switching operations with automatic electronic identification and allocation systems

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

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.
