Fan Driving Circuit Feedback for Real-Time Fault-Aware Cooling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fan management systems cannot accurately determine the real-time operational status of fans, particularly in high-temperature applications like 5G high-frequency transmission and AI edge computing, which requires more stringent cooling and stability, limiting their ability to improve fan performance and reliability.
Innovation Solution
A fan management system and method that outputs a digital label signal through the fan's driving circuit when abnormal operation is detected, including production history, operation information, and warning messages, allowing the server to adjust the fan's operation mode and enhance its lifespan.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional fan management systems only use rotation speed signals, then the system structure remains simple, but the system cannot accurately determine real-time operational status and cannot improve fan performance
Solution Approach 1:
The patent implements feedback by having the driving circuit output digital label signals containing operation information back to the server. The server receives these signals and uses them to adjust fan operation modes, creating a closed-loop feedback system that enables real-time monitoring and active adjustment of fan performance based on actual operational status.
2Reliability
If the fan provides current operating conditions immediately, then the reliability of electronic equipment improves, but the conventional system cannot fully know real-time fan operation status
Solution Approach 1:
The driving circuit outputs digital label signals containing comprehensive operation information (production history, operation information, warning messages) to the server, enabling real-time feedback on fan status. This allows the system to immediately know and respond to actual fan operating conditions, improving heat dissipation system reliability.
3Duration of action of stationary object
If the server adjusts operation mode according to warning messages, then fan lifespan increases, but the system requires real-time digital signal output capability
Solution Approach 1:
The driving circuit is designed to perform multiple functions: it not only drives the fan motor but also outputs digital label signals containing operation information. This multi-functionality allows the same circuit to provide both mechanical drive and digital communication capabilities, enabling operation mode adjustment without significantly increasing overall system complexity.

AI summary
A fan management system includes a fan and a server. The fan includes a driving circuit, and the driving circuit is configured for driving the fan. The fan operates in an operation mode. The server is connected to the fan and is configured for controlling the operation of the fan. The driving circuit outputs a digital label signal when the fan operates abnormally, and the server obtains a production history, an operation information and a warning message of the fan through the digital label signal. The server adjusts the operation mode of the fan according to the warning message simultaneously.
