Abstract

PURPOSE:To prevent the dewing and the deterioration of an element by discontinuing the operation of an information processor with an instruction of a system operation device and the switching off a power supply when the temperature slope characteristic exceeds a level set previously. CONSTITUTION:An environment setting range and the allowable temperature slope value are previously set to a system operating device 1. At the same time, a comparator is provided into the device 1 to compare the time information sent from a time device 2 with the temperature slope value calculated from the value of a temperature sensor 3. If the value obtained by dividing the temperature difference of the sensor 3 by the time difference of the device 2 is larger than the allowable temperature slope value, an alarm is sent to information the information processors 101-(101+n) of the environmental abnormality. Thus these information processors perform their stopping operations and switch off their power supplies. Thus it is possible to prevent the dewing of the information processor and the deterioration of an element.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a forced maintenance method, and particularly to a forced maintenance method for monitoring the environment of an information processing device.

[Conventional technology]

Conventionally, this type of maintenance method has been a so-called corrective maintenance method, in which a self-recording temperature recorder is installed for a long period of time, and the data is later analyzed to determine whether the environmental conditions are good or bad.

[Problem to be solved by the invention]

The conventional corrective maintenance method described above involves a lot of trial-and-error improvements based on the results of data analysis, and cannot eliminate the possibility of condensation because the state of air conditioning failure cannot be determined in real time.

■If the condition of poor air conditioning continues for a long time, it will cause stress to the elements and accelerate the deterioration of the elements.

■It is not possible to determine for sure that the cause of the equipment failure was due to poor air conditioning.

There are drawbacks such as:

[Means to solve the problem]

The forced maintenance method of the present invention is a system including an information processing device, an air conditioner, and a system operating device that monitors the operation of each of the devices, the system being connected to the system operating device,
A temperature sensor and a time device are provided for sensing the environmental state of an information processing room in which the information processing device is installed, and further, means for calculating temperature gradient characteristics based on the information of the temperature sensor and time information in the system operating device. is provided, and when the temperature gradient characteristic value set in advance is exceeded, the information processing device is configured to stop operating and further power off in response to an instruction from the system operating device.

〔Example〕

Embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the present invention.

The system operation device 1 includes a time device 2, a temperature sensor 3, an air conditioner 4, and a group of n information processing devices 101 to (101+n).
are connected to each of them.

Next, this operation will be explained.

The system operating device 1 has a built-in circuit that sets the environmental setting range and temperature gradient tolerance in advance, and compares the time information sent from the time device 2 with the temperature gradient value calculated from the value of the temperature sensor 3. are doing. That is, if the value (temperature gradient) obtained by dividing the temperature difference of the temperature sensor 3 by the time difference of the time device ff12 is greater than or equal to the temperature gradient tolerance value, the information processing device group 10
1 to (101+n), an alarm indicating that there is an environmental abnormality is sent out.

After the information processing device group 101 to (101+n) performs a process for stopping, the power is turned off.

Next, this example will be explained in detail.

FIG. 2 is a graph showing the relationship between time and temperature.

Here, the system operating device has a predefined temperature gradient Y≦±1.
/6 (cooling or heating at a rate of 1°C for 6 minutes).

Next, the temperature gradient X is calculated from the temperature information sent from the temperature sensor and the value of the time information T as follows.

In FIG. 2, the temperature gradient from 5:30 AM to 6:30 AM is X, --1/12, which is within the allowable temperature gradient. Similarly, from 7:30AM to 8:30AM, X2
= 1/6. However, from 9=30AM to 10:00
During AM, XS=1/3, which exceeds the allowable temperature gradient, so the information processing equipment group is stopped and the power is turned off.

Although the present invention has been specifically explained above using examples, the present invention is not limited to this embodiment, and may be modified as follows.

■The time device and temperature sensor may be built into the system operating device.

■Calculation of temperature gradient is not limited to 30 minute units;
Any time unit such as seconds or hours may be used.

〔Effect of the invention〕

As explained above, according to the present invention, an environmental abnormality caused by an air conditioning abnormality is accurately detected, so that it is possible to determine that there is an abnormality in the air conditioning.

■If an abnormality occurs in the environment, the power to the information processing equipment group is turned off, thereby preventing deterioration of the elements.

■Prevent condensation on information processing equipment.

There is an effect.
