Problems solved by technology
[0004] However, in the first implementation, the time point of reading temperature data is not controlled by the BMC, and the read temperature will be delayed. In some occasions that require accurate instantaneous temperature values, the polling method cannot meet the demand; the second In this implementation mode, every time the temperature data is read, the BMC needs to initiate an instruction to read and write the temperature data, which greatly reduces the operating efficiency of the BMC.

The present application discloses a temperature acquisition method, which includes receiving first temperature data, the first temperature data is the data obtained by the temperature detection chip regularly reading the temperature of the central processing unit CPU in a polling manner; When the first instruction is issued, the temperature of the CPU is read in real time through a manual command to obtain second temperature data; and the temperature of the CPU is updated according to the second temperature data. This method can combine the polling mode with the manual command mode. Under normal circumstances, the polling mode is used to read the temperature data of the CPU without BMC intervention. When the first command to obtain the CPU temperature is received, it is switched to the manual mode to obtain The second temperature data, in this way, the BMC does not need to frequently initiate an instruction to read the temperature data, so that the BMC maintains a high operating efficiency, and can obtain the CPU temperature accurately and without delay. The application also discloses a temperature acquisition device, equipment and medium.
Description
Technical field [0001] The present application relates to the field of temperature monitoring, and more particularly to a temperature acquisition method, device, apparatus, and medium. Background technique [0002] With the development of information technology, the requirements for Central Processing Unit, CPUs in computing devices are getting higher and higher, especially for CPU temperature control. BaseboardManager Controller, BaseboardManager Controller, BSEBoardManager Controller (BMC) is used to monitor the temperature, voltage, fan, power supply, etc. of the computing device, and perform the corresponding adjustment work according to the monitoring result to ensure that the computing device is in normal operation. [0003] Among them, the temperature of the monitoring computing device is mainly to monitor the temperature of the CPU of the computing device. Two implementations are provided in the prior art for the temperature gain of the CPU. One implementation is to autom...
