s101: temperature information of the battery module is acquired using a temperature acquisition unit.
In this embodiment, after the cluster service is started, the temperature information of the battery module may be acquired by the temperature acquisition unit. The battery module is a module for supplying power to the cluster service, and may be a BBU unit, for example, and the temperature obtaining unit may be a unit for obtaining the temperature of the battery module.
In a specific implementation scenario, referring to fig. 2, a specific implementation schematic diagram of a battery temperature obtaining method provided in an embodiment of the present application is shown, where the temperature obtaining unit may be a functional module named as an EC layer, and the EC layer may obtain the temperature of the BBU unit by accessing an I2C channel.

In this embodiment, it can be understood that, in the process of cluster service operation, as the traffic volume changes in real time, the temperature of the battery module also changes accordingly. Therefore, in order to more accurately acquire the temperature of the battery module, a time interval may be preset and recorded as the first time interval, and then the temperature information of the battery module may be acquired once after every first preset time interval by using the temperature acquisition unit.

In this embodiment, since the temperature information stored in the temperature updating unit is being updated, a second preset time interval may be preset, and the temperature reading unit may be enabled to read the temperature information stored in the temperature updating unit once every second preset time interval. So that the temperature reading unit can read the latest temperature information stored in the temperature updating unit.
In a specific application scenario, as shown in fig. 2, the second preset time interval may be preset to 10s, and the EN layer may read the temperature information stored in the plhdw layer once every 10 s.

Wherein, the page is a computer programming language script. Then, when the EN layer establishes a task of delivering the unloading temperature information carrying the page, the EN layer can try to interact with the OSES first, and after the interaction is successful, the EN layer can process the attribute information of the page according to an SES protocol and encapsulate the page which finishes processing the attribute information into an SES data writing instruction. The ses (SCSI Enclosure service) protocol is a service protocol for querying various states of the chassis based on the SCSI protocol, and the attribute information of a page may refer to information related to the page, such as a page header (page header) of the page, a check bit, and attribute information of a data length of the page. And finally, analyzing the SES data writing instruction through the SCSI protocol, and transmitting the analyzed temperature information to the OSES of the heat dissipation system.
