Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a wind speed monitoring function for monitoring a cooling wind speed in an information system.

[0002]

2. Description of the Related Art In an information system or the like, for example, a fan or a blower is provided inside a housing of the information system. If the fan or blower fails, the temperature inside the housing may rise beyond an allowable range.

For this reason, in order to prevent the system from going down due to a rise in temperature, a device having a function of detecting a wind speed abnormality by providing a wind speed sensor has been developed.

[0004]

Some conventional information systems have a function of detecting a wind speed abnormality by providing a wind speed sensor. However, the conventional function only detects the wind speed abnormality, and when the wind speed abnormality actually occurs, the operator shuts off the system power by display processing by an OS (operating system), for example. Therefore, if the operation of the power switch by the operator is delayed, the function of the system may be inadvertently stopped. In particular, if a network server or an information system inadvertently stops functioning, troubles may occur in information systems connected to other networks.

Accordingly, an object of the present invention is to provide an information processing system in which, when an abnormal wind speed occurs, a shutdown process and a system power-off process can be surely realized without requiring an operator's operation, and the information system is inadvertently shut down. It is to prevent such a situation from occurring.

[0006] The shutdown processing is a normal operation of cutting off the power supply to the information system.

[0007]

SUMMARY OF THE INVENTION The present invention relates to an information system applied to a server or a computer connected to a computer network such as a LAN, for detecting a wind speed of, for example, a fan or a blower inside the system body. The wind speed detecting means (wind speed sensor), a plurality of reference values for comparing with the detected wind speed value, and the detected wind speed value from the wind speed detecting means are monitored, and based on a result of comparison with the plurality of reference values, an abnormality in the internal wind speed is detected. A wind speed monitoring means for detecting the occurrence and performing different abnormal processing according to the internal wind speed abnormality level; controlling the power supply and disconnection of the system main body; notifying a higher-level device according to the level of the abnormal processing of the wind speed monitoring means; The power supply control means for cutting off the normal power supply according to the instruction, and the power supply control wind speed monitoring device itself according to the level of abnormality processing of the wind speed monitoring means. That has an emergency power supply cutting means.

[0008] The plurality of reference value data are obtained by setting a wind speed threshold at which the wind is weak to a first reference value, a wind speed threshold at which the wind is weaker than the first reference value to a second reference value, and a wind speed at which the wind is weaker than the second reference value. The threshold is set in the memory as a third reference value.

The wind speed monitoring means notifies the host device of the occurrence of the first wind speed abnormality when the detected wind speed value exceeds the first reference value, and outputs the second signal when the detected wind speed value exceeds the second reference value. The occurrence of a wind speed abnormality is notified to the host device, the normal power supply is cut off according to an instruction from the host device, and the occurrence of the third wind speed abnormality is notified when the wind speed detection value exceeds the third reference value. And executes the emergency power-off means by the power control wind speed monitoring device itself.

With this configuration, for example, when a second wind speed abnormality occurs in the server or the information system, the host device receives the notification of the occurrence of the wind speed abnormality, shifts to a normal system disconnection process, and switches the system power supply. Can be shut off. Before the system malfunctions carelessly due to an abnormal wind speed, preparations for stopping the system can be completed, and the system can be stopped normally.

When a third wind speed abnormality occurs,
Since there is a danger that the system will fail, it is possible to prevent the system from failing by urgently shutting down the power supply of the system.

[0012]

DESCRIPTION OF THE PREFERRED EMBODIMENTS (Wind Speed Monitoring Process of the Present Embodiment) The wind speed monitoring process of the present embodiment will be described below with reference to the flowchart of FIG. 2 together with FIG.

As described above, the plurality of threshold data of the power supply control wind speed monitoring device 2 include the first data corresponding to the weak wind speed threshold.
Wind speed threshold Wa, a second wind speed threshold Wb corresponding to a wind weaker than the first wind speed threshold Wa, and a second wind speed threshold Wb
A third wind speed threshold value Wc corresponding to a weaker wind is included.

The power control wind speed monitoring device 2 stores a plurality of threshold data in a memory (step S1).

Thus, the power supply control wind speed monitoring device 2
As described later, different wind speed thresholds Wa, Wb, and Wc for executing the three-stage wind speed monitoring process are set. The power supply control wind speed monitoring device 2 has wind speed threshold values Wa, Wb, W
After setting c, the wind speed detection value S from the wind speed sensor 3 is sampled at predetermined intervals and input to the memory (step S2). As described above, the wind speed sensor 3 detects the internal wind speed of the housing that is the system body of the information system 1.

The power supply control wind speed monitoring device 2 compares the sampled wind speed detection value S with the first wind speed threshold value Wa corresponding to the wind speed threshold value at which the wind is weak, and determines that the wind speed detection value S falls below the wind speed threshold value Wa. Is determined (step S
3).

If not, it is recognized that the current internal wind speed is normal.

When the wind speed detection value S falls below the wind speed threshold value Wa, the power supply control wind speed monitoring device 2 determines that the internal wind speed of the information system 1 is the first wind speed abnormality,
The occurrence of a wind speed abnormality is notified (YES in step S4, S
5).

Here, the wind speed threshold value Wa is an abnormal wind speed value, but a value not enough to stop the system.

Further, the power supply control wind speed monitoring device 2 compares the wind speed detection value S with a second wind speed threshold value Wb corresponding to a wind weaker than the first wind speed threshold value Wa, and determines the wind speed detection value S as the wind speed threshold value Wb. When it falls below, the power control wind speed monitoring device 2 determines that the internal wind speed of the information system 1 is the second wind speed abnormality, and notifies the host device 4 of the occurrence of the second wind speed abnormality (YES in step S6, S7). ). When the host device 4 receives the notification of the occurrence of the second wind speed abnormality, the information system 1 may malfunction.
A shutdown process is instructed (step S8). Furthermore, the power supply control wind speed monitoring device 2 determines the wind speed detection value S and the second
Third wind speed threshold W corresponding to a wind weaker than the wind speed threshold Wa
c, the wind speed detection value S falls below the wind speed threshold value Wc at the same time as the wind speed threshold value Wb.
The occurrence of an abnormal wind speed is notified (YES in step S9, S
10). The power control wind speed monitoring device 2 that has detected the third wind speed abnormality executes the emergency power-off means by the power control wind speed monitoring device 2 itself because there is a risk that the information system 1 may break down (step S11). As described above, according to the present embodiment, first, the internal wind speed of the information system 1 is monitored,
When the wind speed detection value S falls below the wind speed threshold value Wa, the host device 4 is warned that the wind speed is abnormally falling. The decrease in the internal wind speed is assumed to be due to, for example, a failure of a fan or a blower provided in the information system 1.

Then, when the internal wind speed further decreases to such an extent that the function of the system is disturbed, the host device 4 instructs the power supply control wind speed monitoring device 2 to perform a shutdown process.

When the internal wind speed further decreases to the extent that a failure occurs in the system, the power supply control wind speed monitoring device 2 executes an emergency power-off means.

In short, the wind speed monitoring function of the present embodiment
In the first stage, the host device 4 is warned, and in the second stage, the host device 4 is warned.
And shuts down the information system 1 with the power control wind speed monitoring device 2 according to an instruction from the host device 4.

Before shutting down the system power supply 5, the information system 1 can start a shutdown process and make preparations for stopping system functions.

Further, when the internal wind speed of the information system 1 rises to such an extent that the system is urgently stopped, the power supply control wind speed monitoring device 2 automatically shuts off the system power supply 5 without involving the host device 4. be able to.

Since the power supply control wind speed monitoring device 2 periodically reports the detected wind speed value S to the host device 4, the host device 4 can always observe the wind speed value.

In the present embodiment, it is assumed that a warning is issued to the host device 4 at the first stage when an abnormal wind speed occurs, but, for example, an auxiliary fan or a blower may be activated at the same time as the warning.

In this embodiment, the number of wind speed thresholds is three. However, the wind speed threshold may be increased and the power may be cut off finely for each wind speed threshold.

[0029]

According to the present invention, when an abnormal wind speed occurs, a shutdown process and a system power-off process can be reliably realized without the need of an operator's operation, and the information system functions inadvertently. It is possible to prevent a situation in which the vehicle stops.
