As shown in FIG. 1, a computer 1 according to the present embodiment includes a service processor (hereinafter, SVP) 2 for executing the functions of the present invention, a power supply 3, and a central processing unit having a built-in component for measuring an operation time. Equipment (hereinafter C
PU) 4. The CPU 4 includes a plurality of components,
That is, component A30, component B31,...
Consists of Here, the components 30 to 32 are not considered as functions such as a register and an accumulator, and are not considered as LS.
I, IC, resistors, capacitors and other units are shown. S
The VP 2 connects a power-off switch 5, a file 6, a display console 7, and a modem 8, and the modem 8 is connected to a remote maintenance center 11 via a communication line 10. A plurality of programs 20 to 25 are stored in the internal memory of SVP2. That is, a component operation management program 20 for managing the operation time of the components, a power supply control program 21 for controlling the power supply 3 and the power-off switch 5 of the computer 1, and control of data exchange with the maintenance center 11 via the communication line 10. Line control program 2
2. File control program 23 for controlling reading and writing of file 6, CPU control program 24 for controlling CPU 4, and screen control program 2 for controlling display console 7.
5 is stored. The file 6 connected to the SVP 2 stores a component operation management table 9 .

FIG. 2 is a format diagram of the component operation management table in FIG. As shown in FIG. 2, the component operation management table 9 stores information for measuring the operation time of the components 30 to 32 built in the CPU 4. That is, the items for the components A to Z are arranged, and as the items, the component operation start time 100 indicating the time when the component started operating, the component operation time 101 of the integrated component, the component replacement time, In other words, the life of the part 10
2, and a replacement flag 103 indicating that the replacement time has passed for the part. When the component operation time 101 is longer than the component replacement time 102, the replacement flag 103 of the corresponding component is turned on.

FIG. 3 is an operation flowchart of the component operation management program according to the present invention. First, when the power of the computer 1 is turned on, the power is supplied to the SVP 2 and the CPU 4 at the same time, and power is also supplied to all components. S
In VP2, each program is started at the same time as the power is supplied.
The processing procedure shown in is executed. First, the component operation management program 20 stores the current time as a measurement start time (Step 200). Next, the parts operation management program 2
0 sets a periodic timer and waits until a new event occurs (step 201). When an event occurs, the component operation management program 20 receives a notification in the following procedure. (A) periodic interruption, (b) CPU failure,
There are five events: (c) referencing a maintenance center, (d) displaying a display console, and (e) pressing a power-off switch. (A) In the case of a periodic timer interrupt... When no event occurs, a timer interrupt in the component operation management program 20 occurs. (B) When a CPU failure has occurred: The CPU control program 24 detects the CPU failure and notifies the component operation management program 20 of this. (C) When there is a request to refer to the component operation time from the maintenance center 11: The line control program 22 detects this and notifies the component operation management program 20 of this. (D) When the operator requests the display table 7 to display the component operation time ...
The screen control program 25 detects this and notifies the component operation management program 20 of this. (F) Power
When the off switch 5 is depressed ... The power control program 21 detects this and notifies the component operation management program 20 of this.

When the occurrence of the above-described event is notified, the component operation management program 20 subtracts the measurement start time stored in step 200 from the current time, obtains the energization time during this time, and obtains the component operation information in the file 6. The energization time is added to all the component operation times 101 of the management table 9 (step 202). Then, the process branches depending on the event that has occurred (step 203). (A) In the case of a periodic timer interrupt, the component operation management program 20 executes the component operation management table 9 in the file 6
The part operation time 101 and the part replacement time 102 are compared for each part (step 210). However, the exchange flag 10
This is not performed for the parts for which 3 is ON. Next, when there is at least one component whose component operation time 101 is longer than the component replacement time 102, the component operation management program 20 turns on the replacement flag 103 of the corresponding component (step 21).
1). If there is no component longer than the component replacement time 102, the process returns to step 200. Next, the part operation management program 20 notifies the line control program 22 that there is a part whose part replacement time has passed, and thereafter,
The process returns to step 200 again (step 212). The line control program 22 having received the notification sends a component replacement request notification to the maintenance center 11 with the component operation management table 9 attached (step 212). Thereby, the maintenance center 11
Can automatically know that there is a part that needs to be replaced, and can take measures such as preventive maintenance. (B) In the case of a CPU failure, the component operation management program 20 notifies the CPU failure to the line control program 22,
Return to step 200 again. Line control program 22
Sends a CPU failure report to the maintenance center 11 with the parts operation management table 9 (step 220). As a result, the maintenance center 11 can know the operating time of the failed component and can grasp the life of the component.

(C) In the case of referring to the maintenance center, the component operation management program 20 notifies the line control program 22 that the component operation management table 9 has been updated, and then returns to step 200 again. The line control program 22 transfers the parts operation management table 9 to the maintenance center 11 (step 230). As a result, the maintenance center 11 can know the operation status of the parts, and can easily schedule the next maintenance and inspection. (D) In the case of display console display, the component operation management program 20 notifies the screen control program 25 that the component operation management table 9 has been updated, and then returns to step 200 again. The screen control program 25 displays the component operation management table 9 on the display console 7 (step 240). As a result, the maintenance staff can know the operation status of the parts and can use the information as a material for determining what kind of maintenance should be performed. (E) If the power-off switch is pressed, the component operation management program 20 notifies the power supply control program 21 that the component operation management table 9 has been updated, and ends the processing. The power control program 21 turns off the power of the computer 1 (step 250). Thereby, the energization time until the power is turned off can be accurately measured. In addition,
At the time of component replacement, the component operation time 101 of the component operation management table 9 is cleared to 0, the replacement flag 103 is turned off, and the component operation start time 100 is set to the current time. If necessary, a part replacement time 102 is set.

In the embodiment, the power-on time of the component is added to the memory prepared for each component. However, as another method of measuring the power-on time of the component, the power-on time of the component and the power-on time of the component are measured. There is a method of obtaining the difference from the power-off time, and a method of obtaining the time difference from the previous integration time to that time periodically or plural times from power-on to power-off. In the embodiment, the operation time of each part is calculated periodically, the part replacement time prepared for the part is compared with the operation time, and when the operation time exceeds the part replacement time, an external notification is made. However, as another method, the time until the next part replacement time comes, the time when the difference between the operating time of each part and the replacement time is the shortest is determined, the timer is set, and when the time is up, the external time is calculated. There is also a way to notify. With this notification, preventive maintenance can be performed and parts can be replaced if necessary.

In this embodiment, (a) the computer 1
The operation time of each component can be easily measured without requiring a dedicated device. (B) Since the operating time of each part of the computer 1 can be referred to on the spot or at the maintenance center 11, it can be used as maintenance information. (C) In addition, the replacement time of parts is checked for each part of the computer 1, and when the replacement time has passed, the maintenance center 11 is automatically notified, which is useful for preventive maintenance. (D) Further, when a failure occurs in the computer 1, the operating time of the component is automatically notified to the maintenance center 11, and thus is useful as information for performing failure analysis and component replacement.

[0013]

As described above, according to the present invention,
The operation time of each component in the apparatus can be measured without requiring special equipment, and can be utilized as maintenance information by referring to the operation time at a remote location. Further, since the replacement timing of each component is automatically notified to a remote location and the operation time of the component is notified to a remote location even in the event of a device failure, it can be used not only for preventive maintenance but also as information for failure analysis. Furthermore, since the non-operation time of a component can be easily calculated, it is possible to perform preventive maintenance of a component whose life is determined according to the non-operation time.
