Problems solved by technology

At the same time, the spatial resolution of the temperature sensor is insufficient to obtain detailed information on hot spots
If the sensor is not deployed in a suitable position, we cannot accurately obtain the size and maximum temperature of the hot spot, which will not provide sufficient information for subsequent processing

Abstract

The invention discloses a server thermal fault monitoring and diagnosing method based on infrared images. The server thermal fault monitoring and diagnosing method comprises acquiring infrared images and visible-light images of a server in different thermal fault states; carrying out tilt correction processing on the images in each thermal fault state by means of standardization method based on image registration, and determining the region-of-interest including the server in each infrared image by means of a manual segmentation method; converting the image of the determined region-of-interest into a corresponding gray scale image, and extracting an image entropy feature from the gray scale image; carrying out dimension reduction processing on the obtained global entropy and the local entropy row-column mean value feature by means of a PCA method; wherein the feature main component obtained after dimension reduction is used for training a support vector machine classifier; acquiring the infrared image and the visible-light image of the server to be detected, and diagnosing the thermal fault state type of the server by means of the trained SVM model. According to the invention, the management efficiency of management personnel in the data center is greatly improved, and engineering debugging and system maintenance are facilitated.

Description

technical field [0001] The invention belongs to the technical field of image processing, and in particular relates to a method for monitoring and diagnosing thermal faults of servers based on infrared images. Background technique [0002] While the scale of the data center is expanding rapidly, the high-density integration of the server leads to an increase in its heat generation. In order to make the server run normally in a suitable environment without causing downtime accidents caused by excessive temperature, many data centers have to increase cooling. The power of the air conditioner causes high energy consumption and low efficiency in the data center. Therefore, accurately monitoring and controlling the temperature of the computer room, improving the cooling efficiency of the air conditioner, and realizing the energy saving and consumption reduction of the data center have become issues that cannot be ignored in the process of data center construction and maintenance. ...
