Problems solved by technology

[0002] With the advancement of integrated circuit design and semiconductor manufacturing process, the speed of microprocessor processing data is getting faster and faster, but with the complexity of integrated circuits, the heat generated by microprocessors is also increasing. It will affect its work efficiency and reduce its service life, and even cause the computer to crash
In order to avoid the occurrence of the above situation, the heat protection mechanism of the microprocessor generally only designs a temperature boundary value. When the temperature rises to the boundary value, the operating frequency is reduced to avoid the microprocessor from overheating. Although this mechanism provides a preventive microprocessor The method of overheating of the processor, but the abnormal temperature of the microprocessor cannot be detected in advance, so it is not a very effective protection mechanism

no. 1 example

[0028] figure 1 It is a schematic diagram of an overheating protection device of an electronic device according to an embodiment of the present invention. Please refer to figure 1 , the overheat protection device 100 includes: a thermal sensor 110 and a controller 120, wherein the controller 120 can be an embedded controller (Embedded Controller, EC) or a baseboard management controller (Baseboard Management Controller, BMC). The thermal sensor 110 can detect the temperature value of the electronic device 130 . On the other hand, the controller 120 is coupled to the thermal sensor 110 , it can calculate the temperature change slope of the electronic device 130 according to the temperature value measured by the thermal sensor 110 , and determine whether to stop the operation of the electronic device 130 . Wherein, the temperature change slope can be obtained by calculating the change amount of the temperature value measured by the thermal sensor 110 corresponding to time.

[0034] Based on the above, this embodiment can summarize an overheating protection method for electronic devices, such as figure 2 as shown, figure 2 It is a flow chart of the overheating protection method of the electronic device according to the second embodiment, and its steps include: firstly, in step S210, the temperature value of the electronic device is detected and the temperature change slope thereof is calculated. For example, the temperature value of the microprocessor, the ambient temperature value of the electronic device, or the temperature value of the case of the electronic device can be detected, and then the temperature change slope can be calculated. Wherein, the temperature change slope can be obtained by calculating the change amount of the temperature value corresponding to the time.

[0035] Next, in step S220, it is determined whether the electronic device has been turned on for more than a preset period of time. If not, then it is determined whethe...

[0039] image 3 For the flowchart of the overheating protection method of the electronic device according to the third embodiment of the present invention, please refer to image 3 , firstly, in step S310, the temperature value of the electronic device is detected. Next, in step S320, it is determined whether the temperature value of the electronic device is greater than a temperature boundary value. If yes, stop the operation of the electronic device (step S330); if not, enter step S340 to determine whether the preset time of 10 minutes after starting up has passed. If so, go back to step S310 and continue to detect the temperature of the electronic device; if it has not exceeded 10 minutes, then calculate the temperature change slope every 3 seconds, as shown in step 350 . Next, it is judged whether the temperature change slope is greater than a preset slope. If yes, stop the operation of the electronic device (step S330); if not, return to step S310 and continue to detec...

Abstract

The invention provides an overheating protection device and method of an electronic device. The method of the invention comprises the following steps: testing the temperature value and temperature variation slope of the electronic device; if the temperature variation slope is more than a preset slope or the temperature value is more than a temperature boundary value during a preset time after starting the electronic device, stopping the operation of the electronic device. By adopting the method of the invention, the temperature anomaly of the electronic device can be found early so as to effectively prevent the overheating of the electronic device.

Description

technical field [0001] The invention relates to an overheat protection device and method for an electronic device, and in particular to an overheat protection method for temperature monitoring of an electronic device. Background technique [0002] With the advancement of integrated circuit design and semiconductor manufacturing process, the speed of microprocessor processing data is getting faster and faster, but with the complexity of integrated circuits, the heat generated by microprocessors is also increasing. It will affect its working efficiency and reduce its service life, and even cause the computer to crash in severe cases. In order to avoid the occurrence of the above situation, the heat protection mechanism of the microprocessor generally only designs a temperature boundary value. When the temperature rises to the boundary value, the operating frequency is reduced to avoid the microprocessor from overheating. Although this mechanism provides a preventive microproce...
