Device 4.

Although FIG. 1 omits and shows only one information processing device 1 and one calculation result display device 4, the system of this embodiment has a plurality of components having the same configuration. It is assumed that the information processing device 1 and the calculation result display device 4 are included.

In the system of the present embodiment, 1
One or a plurality of information processing devices 1 are arranged under a user (hereinafter, referred to as a user) such as a company,
The monitoring and notification device 3 intensively monitors a plurality of information processing devices 1 owned by a plurality of users. The information processing equipment 1 is regularly inspected and maintained, for example, every month by a maintenance department in charge of each user.

The present embodiment further includes a monitoring and notifying device 3 for notifying the calculation result display device 4 of information on parts to be replaced.

The monitoring and notification device 3 obtains the usage status of each component included in the information processing device 1, calculates the time when each component reaches its life (hereinafter referred to as replacement time), and The part name to be replaced at the next periodic inspection performed by the department in charge is identified based on the name of the part to be replaced, and the name of the part to be replaced is assigned to the user who owns the information processing apparatus 1 including the part. Is output to the calculation result display device 4 arranged in the.

Each department receives information on the part to be replaced via the calculation result display device 4 and executes the part replacement based on the information, thereby preventing the occurrence of a failure caused by the deterioration of the part. be able to.

The information processing apparatus 1 includes a central processing unit 11 for performing various calculation processes, an input / output device group 12 such as a CRT and a keyboard for instructing execution of the various processing calculations and displaying calculation results, and a central processing unit. Usage status acquisition means 13 for obtaining the usage status of the components provided in the device 11 and the input / output device group 12, and usage status file storage means for recording the usage status of each component obtained by the usage status obtaining means 13 15 and usage status file storage means 15
Log information transfer unit 1 that transfers information on the use results of each component stored in the storage unit to the monitoring and notification device 3 at a predetermined cycle.
And 4.

The components provided in the information processing apparatus 1 are those whose performance deteriorates due to aging and wear. For example, a built-in battery for memory backup, a cooling fan,
There is a power supply unit and the like.

The usage status acquisition means 13 directly or indirectly obtains the usage results of these parts to be replaced, and writes the results to the usage status file storage means 15.

More specifically, for example, in order to acquire the usage record of the cooling fan attached to the central processing unit 11, the use status acquisition means 13 uses the central processing unit 11 to which the cooling fan is attached. Detects the period from the time the power switch is turned on to the time the power switch is turned off.
The use time of the cooling fan is acquired by sequentially adding the use times. This is because the cooling fan is turned on and off in conjunction with the power supply of the central processing unit 11, and the time when the central processing unit 11 is used is always used.

For the built-in battery for memory backup attached to the central processing unit 11, the use status acquisition means 13 operates during a period when the central processing unit 11 is not turned on, that is, when the power is turned off. The period until the next insertion is set as one use period of the built-in battery, and the use results are acquired by sequentially adding the use periods.
This is because the built-in battery is used when the central processing unit 11 is not used.

For a component such as a power supply unit whose performance becomes unstable due to deterioration, the performance or the instability of the performance is monitored instead of directly obtaining the use time. Such a configuration is adopted. For example, the use status acquisition unit 13 measures the voltage of the power supply unit at a predetermined cycle, and acquires the magnitude of the variation of the measured voltage instead of the use result.

In this embodiment, a cooling fan, a built-in battery,
The power supply unit and the like have been described as an example, and the method of obtaining the usage status has been described.However, the components that can obtain the usage status in the present invention include:
The present invention is not limited to these components, and the use status of other components can be obtained according to the use status, as in the present embodiment.

The usage status file storage means 15 is realized by a recording device such as a hard disk, and is specifically a specific storage area provided in the recording device.

The information stored in the usage status file storage unit 15 includes, for example, information indicating an information processing device identification ID for specifying the usage status file information processing device 1, the date and time of acquisition of the usage record, and the information. Processing equipment 1
Includes the actual use value of each component provided in.

The log information transfer unit 14 is connected to the monitoring and notification device 3 via a line such as a telephone, and reports the usage status of each component acquired and stored at a predetermined cycle to the monitoring and notification device 3. Transfer to The information transferred by the log information transfer unit 14 mainly stores the usage status file storage unit 15.
As shown in FIG. 2A, for example, as shown in FIG. 2A, a customer code 201 and a device model name 202 as an information processing device identification ID 200, a transfer date / time or a use result acquisition date / time 210, and a use result value 220 and a component name 221.

The monitoring notification device 3 is realized by a computer and a storage device, and includes a log information transfer unit 1
Log information receiving unit 31 that receives the information transferred from the server 4
A use result change tendency calculating unit 32 that calculates an increase tendency of the use result of each component using the use result value of each component included in the received information; and a calculated increase tendency of the use result. The part replacement time is calculated, and based on the calculated part replacement time and a predetermined inspection schedule of the department in charge of the information processing device 1 to which this part is attached, the responsible department is scheduled for the next time. It has a component replacement time calculation unit 33 for specifying a component name to be replaced at the time of inspection, and a calculation result notification unit 34 for notifying the specified component name to the calculation result display device 4 arranged in the department in charge.

As the information to be notified as the calculation result, for example, as shown in FIG. 2D, the customer code 201 and the device model name 202, which are IDs for identifying the information processing device 1, It includes a predetermined next regular inspection date 251 and a replacement part name 252 to be replaced at the time of the inspection.

The monitoring notification device 3 further includes a log information file storage unit 35 for storing the information received by the log information receiving unit 31 and a change in the component life and the usage record which are predetermined for each component. A calculation method for storing a calculation method, etc., a life comparison data file storage unit 36, a department assigned to each user who uses the information processing device 1, and a calculation result that is a communication terminal arranged in the department in charge. And a notification destination specifying table file storage unit 37 for storing the ID of the display device 4.

A detailed description of each unit of the monitoring notification device 3 and a specific example of the information stored in each file storage unit will be described later together with a description of the system operation of this embodiment.

The calculation result display device 4 indicates the name of the component that needs to be replaced at the next inspection output from the monitoring notification device 3 (FIG. 2).
(Refer to (d)), a calculation result receiving unit 40 for receiving the information on (1), and a display device 4 such as a CRT for displaying the received information.
1, an input device 42 such as a keyboard and a mouse, and an output device 43 such as a printer that prints out the calculation result as needed.

Next, the detailed description and the processing operation of the monitoring and notification device 3 will be described with reference to FIGS. 2, 3 and 4.

In this embodiment, first, as shown in the flowchart of FIG. 3, the log information receiving unit 31 transmits the information (FIG. 2 (a)) transferred from the log information transfer unit 14 via a line such as a telephone. ) Is received and stored in the log information file storage means 35 (step 301).

Here, the log information file storage means 35
Performs the above-described operation periodically, and sequentially stores newly collected information in addition to information collected in the past.

Next, the usage result change tendency calculating section 32 calculates the past usage values of each component stored in the log information file storage means 35 which are obtained from the latest value to the predetermined time. By using a predetermined number of pieces of data, the increasing tendency of the actual use of each component is calculated (step 302).

When calculating the increasing tendency of the usage results, a calculating method is selected according to the deterioration characteristics of the component for which the increasing tendency is calculated. This calculation method is determined in advance for each part, and the correspondence between the part and the calculation method is stored in the calculation method life comparison data file storage means 36 as shown in FIG. I have.

The use result change tendency calculating section 32 reads out the stored correspondence and calculates an increase tendency of the use result of each component. An example of this calculation method is:
This will be described with reference to FIG.

In the calculation method shown in FIG. 4, it is assumed that the cumulative use result increases linearly, and a function representing the cumulative use result is calculated using a predetermined number of use result data.
It is approximated by a straight line. That is, the number n of use result data obtained so far is n, the use result of each data is yi (i = 1 to n), and the acquisition time of each data is ti (i
= 1 to n), a linear approximation formula (primary regression line) f
The slope a of (t) is obtained by the following equation.

[0039]

(Equation 1)

Next, the part replacement time calculator 33 calculates the inclination a and the calculation method life comparison data file storage means 36.
The replacement time T0, which is the time when the actual use time of the component reaches the predetermined component life, is calculated using the component life Y0 stored in the storage device (step 303).

From the slope a obtained above, the linear approximation f (t) can be expressed as follows.

[0042]

(Equation 2)

Therefore, T satisfying f (T0) = Y0
By calculating 0, the component replacement time T0 can be obtained.

Instead of using a straight line as in the calculation method shown in FIG. 4, another calculation method uses the same actual use data as above and uses a curve of a predetermined order. You may do it.

Also, the instability of the performance of a component, such as a power supply unit, is measured instead of the performance record, and a threshold is set as the limit of the instability instead of the service life of the component. The value may be used to determine when to replace the part. In this case, for example, a calculation method approximated by an exponential function curve may be used. This is because it is known that the performance of a component often increases instability due to deterioration almost exponentially, rather than linearly.

The part replacement time calculation unit 33 further determines whether or not the obtained replacement time T0 is between the next periodic inspection of the department in charge of replacing the part and the next periodic inspection (step S1). 304).

For example, the replacement time T from the most recent inspection date
0 and a date twice as long as the inspection cycle predetermined for each part stored in the calculation method life comparison data file storage means 36 (for example, two months if the inspection is performed every month). Compare.

If it is a time before the next periodic inspection (No in step 304), the process returns to step 301. If it is between the next and the next periodic inspection (Yes in step 304), the process proceeds to step 305.

In step 305, the part replacement time calculation unit 33 further sets the part name of the part whose replacement time is between the next and subsequent inspections as described above as the part name to be replaced at the next inspection. The information is listed for each information processing device 1.

In step 305, the calculation result notifying unit 34 further notifies the notification destination specifying table file storage unit 37.
2 (c), the part replacement time calculation unit 33 is responsible for the inspection of the user using the information processing device 1 having the parts to be replaced listed. It specifies the department in charge and the calculation result display device 4 which is a notification terminal arranged in the department in charge.

In the notification destination specifying table file storage means 37, as shown in FIG. 2 (c), the user name (customer code 201) assigned to each department in charge and the information assigned to each department in advance are stored. The data about the notification terminal ID 241 that specifies the calculation result display device 4 that is present is stored.

The calculation result notifying section 34 further sends information (see FIG. 2D) on parts to be replaced at the next inspection by the department in charge where the specified calculation result display device 4 is disposed. It is generated based on the names of the parts to be replaced listed by the timing calculation unit 33, and is output to the specified calculation result display device 4.

The calculation result display device 4 accepts the information on the above-mentioned component replacement and outputs the information on the component replacement to the display device 41 or the output device 43.

Each department in charge can replace the components of the information processing device 1 on the next inspection date in response to the component replacement instruction notified in this manner.

According to the present embodiment, the use status of the components provided in the information processing apparatus 1 can be grasped more accurately, and the more accurate replacement time of each component can be predicted. In addition, based on the predicted replacement time, it is possible to notify the department in charge of replacement of the part when and which part should be replaced during the regular inspection. The efficiency of inspection work can be improved.

Further, as a result, the components provided in the information processing apparatus 1 can be replaced at a more appropriate time.
It is possible to prevent troubles caused by deterioration of parts.

Also, since the parts replacement instruction is notified to each department in charge so that the parts can be replaced by using the inspection work that is regularly performed in advance, each department in charge has
It is not necessary to visit the user only for replacement of parts other than the periodic inspection.

[0058]

According to the present invention, it is possible to predict a component replacement time more accurately, and to provide a component replacement time monitoring system capable of more appropriately instructing a time to replace a component. it can.
