Embodiments of the present invention are directed to systems and methods for controlling the temperature of an internal device while reducing or minimizing the involvement of the host. Thus, some of the heat monitoring and remediation work may be offloaded to the actual device itself. The device may monitor its own temperature and, in the event of high temperature, perform device specific heat reduction actions without involving the host. Furthermore, the device may, upon detecting temperature within a predefined range, alert the host of a high temperature condition in order to allow the host to perform temperature reduction measures. Also, the device may, upon detecting temperature within a predefined range, alert the host of an impending device shutdown and shut the device down. In addition, the device may periodically save its temperature into non-volatile memory in order to create a temperature log.

The embodiment of the invention discloses a method and device for recording a high-temperature log on an SOC and a computer readable storage medium. A CPLD judges whether a thermal disconnection signal is received or not; taking a low level as an effective level as an example, since the continuous pull-down time of the thermal circuit break signal on the SOC system is short, the BMC can detect thepin level of the thermal circuit break signal at an interval of a long time, and the BMC can realize the collection of log information only when the pin level is the low level. Therefore, in the technical scheme, when the CPLD receives the thermal disconnection signal, a preset delay program is called to perform delay processing on the thermal disconnection signal, so that the level of the pin where the thermal disconnection signal is located can be kept at a low level for a long time, and the BMC can conveniently and smoothly record the log information of CPU high-temperature alarm. By prolonging the duration of the thermal disconnection signal, the problem that the SOC system cannot smoothly collect log information when a CPU gives an alarm at a high temperature is effectively solved.
