Solution Overview
Problem
Current technologies for managing edge servers in rugged environments focus primarily on hardware reinforcement and do not effectively address power consumption and cooling efficiency, particularly in extreme temperatures and humidity, leading to potential breakdowns and increased power usage.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If cooling fan rotation speed is increased to cool edge servers in high temperature environments, then cooling efficiency is improved, but power consumption increases significantly
Solution Approach 1:
The patent applies local quality by dividing the chassis into multiple zones with different thermal characteristics and controlling cooling fans in each zone independently based on local temperature conditions. The BMC collects temperature data from specific zones and adjusts fan speeds locally rather than uniformly across the entire chassis, allowing high cooling efficiency in hot zones while maintaining low power consumption in cooler zones.
Solution Approach 2:
The patent implements dynamics by dynamically adjusting cooling fan rotation speeds in real-time based on changing temperature conditions, workload patterns, and environmental factors. The BMC continuously monitors temperature data and modifies fan control parameters adaptively, transitioning from static to dynamic cooling control to optimize the balance between cooling efficiency and power consumption.
2Reliability
If hardware reinforcement is applied to improve rugged environment operation, then reliability in extreme conditions is improved, but power consumption and cooling requirements increase
Solution Approach 1:
The patent applies parameter changes by adjusting cooling fan operation parameters (rotation speed, duty cycle) based on environmental conditions, workload parameters, and thermal measurements. The BMC modifies operational parameters dynamically to maintain reliable server operation in rugged environments while minimizing power consumption through optimized cooling strategies rather than continuous high-speed fan operation.
3Use of energy by moving object
If zone-based cooling control is implemented through BMC data analysis, then power consumption is reduced, but system complexity increases
Solution Approach 1:
The patent implements self-service by enabling the BMC to autonomously collect temperature data from various zones, analyze thermal conditions, and automatically adjust cooling fan speeds without external intervention. The system performs self-diagnosis and self-control of cooling operations, reducing the need for complex external control mechanisms while achieving optimized power consumption through intelligent, autonomous decision-making.

AI summary
There is a method for applying a BMC analytical local fan control model in a rugged environment. A server chassis cooling fan control method according to an embodiment controls rotation speeds of cooling fans on a zone basis while identifying/managing a temperature distribution of an edge server chassis on a zone basis through BMC data analysis. Accordingly, a damage that may be caused by increased temperature of an edge server in a rugged environment may be minimized, and also, power consumption for cooling an edge server may be reduced.
