Description

technical field [0001] The invention relates to the technical field of temperature monitoring, in particular to a fan monitoring device and a monitoring method thereof. Background technique [0002] In many large-scale equipment, because many of the components will generate a lot of heat, in order to ensure the normal operation of the equipment, multiple fans must be used to cool the equipment by forced air to reduce the operating temperature of the system. However, a fan rotating at high speed will generate noise, and the decibel number of the noise increases with the increase of the air cooling intensity, so how to solve the fan noise is very critical in the design of large equipment. [0003] For example, in communication equipment, since the traditional fan itself does not have the function of intelligently monitoring its intensity, it is necessary to design the monitoring of the fan in the equipment to minimize the noise of the fan. At present, a common practice is to ...
