DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a computer system such as a server connected to a computer network, and more particularly to a temperature monitoring function for monitoring the internal temperature of the system body.

[0002]

2. Description of the Related Art Conventionally, for example, LAN (Local Ar)
In a computer network such as ea Network, a plurality of computers (personal computers and the like) are connected, for example, a client server system is configured, and various types of information are exchanged.

A personal computer used as a client or a server is provided with a fan (cleaning fan) inside a housing of a computer body (system body). If this fan fails or the temperature of the external environment rises abnormally, the temperature inside the housing may rise beyond the allowable range. For this reason, in particular, a server having a function of detecting a temperature abnormality by providing a temperature sensor has been developed in order to prevent a system down due to a rise in temperature.

[0004]

As described above, some computers such as conventional servers have a function of detecting a temperature abnormality by providing a temperature sensor. However, the conventional function merely detects the temperature abnormality, and when the temperature abnormality actually occurs, the operator shuts off the system power supply by a display process 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 the function of the server on the network is inadvertently stopped, other clients and the like also suffer.

Accordingly, an object of the present invention is to provide a computer system such as a server which can reliably perform shutdown processing and system power supply shutdown processing without requiring an operator's operation when a temperature abnormality occurs. It is to prevent such a situation that it will stop functioning.

[0006]

SUMMARY OF THE INVENTION The present invention relates to a computer system applied to a server or the like connected to a computer network such as a LAN, and a temperature detecting means (temperature sensor) for detecting an internal temperature of the system body.
And setting means for setting a plurality of reference values for comparison with the detected temperature value, and monitoring of the detected temperature value from the temperature detecting means to detect an abnormality in the internal temperature based on a result of comparison with the plurality of reference values. Temperature monitoring means for detecting occurrence and performing different abnormal processing according to the abnormal level of the internal temperature, and controlling the power supply of the system body, and supplying power according to a power-off instruction given according to the abnormal processing of the temperature monitoring means. It has a power supply control means for stopping and a system control means for executing a shutdown processing of the system in response to the notification of the temperature abnormality occurrence given according to the abnormality processing of the temperature monitoring means.

[0007] The setting means converts, for example, a plurality of reference value data transmitted from a client connected to the network to a first reference value corresponding to a relatively low temperature threshold and a second reference value corresponding to a relatively high temperature threshold. 2 is set in the memory as a reference value. The temperature monitoring means notifies the OS of, for example, occurrence of a temperature abnormality when the detected temperature value exceeds the first reference value, and instructs the power supply control means to shut off the power supply when the detected temperature value exceeds the second reference value. To instruct.

With this configuration, for example, when the temperature inside the server rises abnormally, the system control means (O
In step S), upon receiving the notification of the temperature abnormality occurrence, the system shutdown process can be performed. The shutdown process includes a process of storing data necessary for various data processes being executed by the CPU in a non-volatile storage device such as a hard disk device. Further, the power supply control means (power supply controller) of the system can cut off the system power supply in response to the instruction to cut off the power supply. Therefore, before the system stops functioning carelessly due to abnormal temperature, preparations for stopping the system can be completed and the system can be stopped normally.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing a main part of a computer system related to this embodiment, and FIG. 2 is a flow chart for explaining the operation of this embodiment. (System Configuration) The present embodiment is a network system including a plurality of computers connected to a computer network, in which a server 1 and a client 2 are L
Assume a configuration connected to AN3. The server 1 and the client 2 each execute data communication via the modem 4 and exchange various data with each other.

The server 1 has a power supply controller 11 and a dedicated board 12 for realizing extended functions, in addition to basic components (CPU, memory, etc.) operated by an OS (Operating System). Here, basic components such as a CPU including an OS are referred to as an OS 10 for convenience.

The power supply controller 11 controls the supply and cutoff of the system power supply of the server 1. In this embodiment, when the power supply cutoff instruction from the temperature monitoring module 13 mounted on the dedicated board 12 is notified, the system power supply 11 is turned off. To turn off the power supply.

The dedicated board 12 has various extended functions other than the temperature monitoring function of the present embodiment. As the temperature monitoring function, a temperature monitoring module 13 and a temperature sensor 14 are mounted. The temperature sensor 14 is a sensor for detecting the internal temperature of the housing forming the system body of the server 1. Further, the dedicated board 12 is connected to, for example, an ISA bus in the system main body, and is connected via the ISA bus.
S10 and the power supply controller 11 are connected.

The temperature monitoring module 13 is composed of a CPU and temperature monitoring application software as a specific configuration, and monitors the fluctuation of the internal temperature of the server 1,
Various abnormality processing when a temperature abnormality occurs (described later)
Execute The temperature monitoring module 13 includes the temperature sensor 1
The temperature detection value from 4 is sampled at a predetermined interval, the set temperature threshold value (reference value) is compared with the temperature detection value,
Monitor the occurrence of abnormal temperatures exceeding the temperature threshold.

In this embodiment, the client 2 has a threshold setting module 15 for the temperature threshold, and has a function of setting threshold data indicating the temperature threshold to the temperature monitoring module 13 of the server 1 via the LAN 3. The threshold setting module 15 has a function of setting a first temperature threshold corresponding to a relatively low temperature threshold and a second temperature threshold corresponding to a relatively high temperature threshold. Temperature monitoring module 1
3 is threshold data (first data) set by the client 2
Has a memory for holding the temperature threshold value Ta and the second temperature threshold value Tb). (Temperature Monitoring Process of the Present Embodiment) Hereinafter, the temperature monitoring process of the present embodiment will be described with reference to the flowchart of FIG. 2 together with FIG.

First, threshold data indicating a temperature threshold (a reference value for temperature monitoring) is transmitted from the client 2 to the server 1 via the threshold setting module 15. As described above, the threshold data includes the first temperature threshold Ta corresponding to a relatively low temperature threshold and the second temperature threshold Tb corresponding to a relatively high temperature threshold. On the server 1 side,
When the temperature monitoring module 13 receives the threshold data, it stores it in the memory (step S1). As a result, the temperature monitoring module 13 sets different temperature thresholds Ta and Tb for executing the two-stage temperature monitoring process, as described later.

The temperature monitoring module 13 has a temperature threshold Ta,
After the setting of Tb, the temperature detection value S from the temperature sensor 14 is sampled at predetermined intervals and input to the memory (step S2). As described above, the temperature sensor 14 detects the internal temperature of the housing that is the system body of the server 1.

The temperature monitoring module 13 compares the temperature detection value S sampled and input with the first temperature threshold value Ta corresponding to a relatively low temperature threshold value, and the temperature detection value S exceeds the temperature threshold value Ta. It is determined whether or not there is (step S3). If not, the internal temperature at this point is recognized as normal.

When the detected temperature value S exceeds the temperature threshold value Ta, the temperature monitoring module 13 determines that the internal temperature of the server 1 has risen abnormally, and notifies the OS 10 of the occurrence of the temperature abnormality ( YES in step S4, S5).
Here, the temperature threshold value Ta is an abnormal temperature value, but a value that is not enough to stop the system urgently. OS
Upon receiving the notification of the occurrence of the abnormal temperature from the temperature monitoring module 13, the 10 shifts to the shutdown process (step S6). The shutdown process is the CPU of the server 1
For storing data necessary for various types of data processing being executed in a nonvolatile storage device such as a hard disk drive (HDD). By this shutdown processing, when the system is restarted after the power supply is stopped, the system can be returned from the state at the time of the stop. Normally, the server 1 has a backup power supply in addition to the system power supply (main power supply), and uses this backup power supply to complete the shutdown process.

Further, the temperature monitoring module 13 compares the detected temperature value S with a second temperature threshold value Tb corresponding to a relatively high temperature threshold value, and when the detected temperature value S exceeds the temperature threshold value Tb. The power supply controller 11 is instructed to turn off the power (shut down the system power supply) (YES in step S7, S8). At this time, the temperature monitoring module 13 executes a power-off instruction after confirming that the shutdown processing of 0S10 is completed. Upon receiving the power-off instruction, the power controller 11 stops the system power supply of the server 1 (step S9). Here, the temperature threshold Tb is a temperature value that is high enough to stop the system urgently.

As described above, according to the present embodiment, first, the internal temperature of the server 1 is monitored, and when the detected temperature value S exceeds the temperature threshold value Ta, the temperature is abnormally transmitted to the OS 10. Warning that it is rising. This increase in the internal temperature is assumed to be due to, for example, a failure of a fan provided in the server 1. Then, when the internal temperature further rises and rises to such an extent that the function of the system is impaired, the system power is shut off. In short, the temperature monitoring function of the present embodiment warns the OS 10 of the server 1 in the first stage, instructs the power controller 11 in the server 1 to shut off the power in the second stage, and stops the power supply of the system.
Therefore, before shutting down the system power, the OS 10 of the server 1 can start the shutdown process and prepare for stopping the system function. Further, when the internal temperature of the server 1 rises to an extent that the system is urgently stopped, the server 1 can automatically cut off the power supply without the involvement of the operator.

Secondly, since the client 2 has a temperature threshold setting function, in the computer network such as a LAN, the client 1 also has the server 1
Has a function of monitoring the internal temperature of the device. Therefore, the normal function of the server 1 can be maintained and the network function such as data exchange between the server 1 and the client 2 can be supported from the client 2 side.

In this embodiment, it is assumed that the OS 10 of the server 1 is warned in the first stage when a temperature abnormality occurs, but at the same time, the temperature monitoring module 13 also notifies the client 2 of the occurrence of the abnormal temperature. It may be configured to perform. If the temperature does not rise so as to reach the second-stage temperature abnormality from the first-stage temperature abnormality, it is not always necessary to turn off the system power, and another abnormality process may be executed (step S7). NO, S10). Specifically, for example, the OS 10 may stop supplying power to peripheral devices so as to significantly reduce power consumption. (Modification of this Embodiment) FIG. 3 is a flow chart for explaining the operation related to the modification of this embodiment. This modified example is a method in which the server 1 monitors the internal temperature of the client 2 using the temperature monitoring module 13 mounted on the dedicated board 12. It is assumed that the client 2 has a temperature sensor for detecting the internal temperature of the main body.

As described above, the temperature monitoring module 13 of the server 1 has the temperature threshold value Ta for monitoring the temperature,
Tb is set in the memory (step S20). The setting process of the temperature thresholds Ta and Tb is executed by the threshold setting module 15 of the client 2 as described above.
Alternatively, when the temperature monitoring module 13 of the server 1 includes a module (application program) corresponding to the threshold setting module 15, the temperature may be set on the server 1 side.

The temperature monitoring module 13 of the server 1 is L
The temperature detection value S from the temperature sensor 14 is received at a predetermined interval from the temperature sensor of the client 2 via the AN 3 and stored in the memory (step S21).

The temperature monitoring module 13 compares the sampled temperature detection value S with a first temperature threshold Ta corresponding to a relatively low temperature threshold, and determines that the temperature detection value S exceeds the temperature threshold Ta. If there is, the client 2 is notified of the occurrence of the temperature abnormality (YES in step S23,
S24). The client 2 may execute the system shutdown processing as described above upon receiving the notification of the abnormality occurrence.

Further, the temperature monitoring module 13 compares the detected temperature value S with a second temperature threshold value Tb corresponding to a relatively high temperature threshold value, and when the detected temperature value S exceeds the temperature threshold value Tb, An instruction to turn off the power (power off the system power supply) is transmitted to the client 2 (step S25).
YES, S26). When the client 2 receives the power-off instruction, the system power supply may be stopped.

With this modification, the temperature of the client 2 can be monitored from the server 1 side, but it goes without saying that both the server 1 and the client 2 have an application for realizing such a temperature monitoring function. Requires software.

[0028]

As described above in detail, according to the present invention, particularly in a computer network such as a LAN, when the internal temperature of the computer of the server or the client rises abnormally due to a factor such as a fan failure, It is possible to surely realize the shutdown processing and the system power-off processing necessary for stopping the function of the system without requiring an operator's operation. In other words, the power supply control of the system can be performed with the necessary preparation before the system is inadvertently stopped functioning due to the temperature abnormality.
