Abstract

PURPOSE:To surely secure a data saving time without depending upon the inclination of a temperature rise. CONSTITUTION:When the internal temperature of the computer detected by a temperature sensor 18 reaches a prescribed temperature abnormality detecting temperature TA, a microcomputer 20 finds out time SB passing a temperature difference TBA equal to a temperature difference TAC between a temperature abnormality detection temperature TA and a power supply disconnection temperature TC, calculates a time difference SBA between the time SB and time SA arriving at the temperature TA and informs the time difference SBA to a CPU 11 as time required up to the disconnection of a power supply. The CPU 11 receiving the information selects temperature abnormality processing to be completed within the time and saves data necessary for the restart of the system from a main storage device 12 to an auxiliary storage device 15.

[Problem to be solved by the invention] In a computer system,
When the power is turned off in the event of a temperature abnormality, data indicating the operating status of the system stored in the main storage device is transferred to auxiliary storage backed up by an auxiliary power source, etc., in order to facilitate restarting the system. It is necessary to save the data to a device to prevent it from being lost.

Assuming that the temperature slope is constant, the time SAC from the current temperature TB to the power-off temperature TC is equal to the above-mentioned time SBA, so the microcomputer 20 calculates the time SAC (=SBA ) is notified to the central processing unit 11 as the time until the power is turned off.

Next, a second embodiment of the present invention will be described. The basic configuration of this embodiment is the same as that in FIG. In this example, if the time required to save data necessary for restarting the system (data save time: SBA) is known in advance, the current detected temperature TA inside the computer and the data save time minutes before the data save time are calculated. The temperature difference TBA from the temperature TB is

In this temperature abnormality detection method, the temperature is determined when the temperature difference between the internal temperature before the data save time and the current internal temperature TA becomes equal to the temperature difference between the current temperature TA and the power cutoff temperature TC. Since it is determined that there is an abnormality, it is possible to always secure data saving time in a range where the temperature increases linearly, even if the slope of the temperature increase is steep. In this case, the temperature abnormality detection temperature that notifies the central processing unit 11 of the occurrence of a temperature abnormality is not a fixed temperature as in the first embodiment, but changes dynamically depending on the slope of the temperature rise.

For example, in a temperature abnormality detection method in which the temperature abnormality detection temperature is fixed, various conditions are taken into consideration, such as when the slope of temperature rise is steep, when the slope is gentle, when the ambient temperature is high, and when the ambient temperature is low. Since the temperature abnormality detection temperature at which it is determined that the temperature is abnormal is set, the determination temperature is set to be relatively low, resulting in a problem that the operating temperature range of the device is narrowed.

In contrast, in the temperature abnormality detection method of this embodiment, even if a temperature abnormality occurs, the temperature abnormality is determined based on the temperature that corresponds to the slope of the temperature rise at that time. For example, if the temperature rise is steep, a temperature abnormality will be determined at a slightly lower temperature; if the temperature rise is gradual, a temperature slightly higher than that temperature will be determined to be abnormal, and the operating temperature range of the device will be limited. Can be expanded substantially.

In the above embodiment, after notifying the central processing unit 11 of the temperature abnormality, if the internal temperature falls below the temperature abnormality detection temperature, the central processing unit 11 is notified that the temperature abnormality has been recovered. Then, the processing performed before the temperature abnormality may be resumed.

Furthermore, cutting off the power after notification of temperature abnormality is as follows:
The cutting may be performed after receiving a cutting instruction from the central processing unit 11. Further, in the above-described embodiments, the case where the power of the computer is cut off when temperature abnormality is detected is explained, but the present invention can also be applied to the case where the operation of the system is stopped by a method other than cutting off the power.

According to the present invention, when a temperature abnormality is detected, for example, the time until the power is cut off is calculated and notified to the central processing unit, so that the central processing unit can perform processing to be completed within that time. By selecting this option, you can ensure that the information necessary for rebooting is saved. In addition, if the temperature is determined to be abnormal when the temperature rise value from before the data save time to the present becomes equal to the temperature difference between the current temperature and the power cutoff temperature TC, the data save time can be ensured. Since temperature abnormality can be determined at a temperature that matches the slope of the temperature increase, the operating temperature range of the computer system can be expanded compared to the conventional method.
