Abstract:The abnormal high temperature of server equipment will form hot spots in the computer room, which will not only affect the stability and life of the server, but also lead to the reduction of the cooling efficiency of the room, thus increasing the cooling energy consumption and operating costs of the room. There are many reasons for hot spots, such as poor air circulation, fan failure, long-term full-load operation and so on. Through automatic diagnosis of the cause of hot spots, the hot spots can be targeted to eliminate, provide data support for the environment control of the computer room, and help to reduce the cooling energy consumption. According to the infrared image taken by the thermal camera on the side of the outlet of the server, a method of automatically diagnosing the cause of hot spots is proposed by using artificial intelligence technology. Aiming at the problem of insufficient hot spot images in practical engineering application, a solution based on Deep Convolution Generative Adversarial Networks (DCGAN) composite hot spot images is proposed. The validity of the method was verified by multiple experiments, and the diagnostic accuracy was about 95%.
