Abstract

PURPOSE:To detect a failure within a short time by storing a normal ON processing time, starting clocking operation from the ON time of a power supply, and if a count value exceeds the normal ON processing time, deciding the abnormality of a device. CONSTITUTION:A time-out detecting means 7 compares the ON processing time sent from a reading means 8 with a clock data occasionally sent from a clocking means 3. The comparison between the ON processing time and the clocking data is continued until the succeeding detecting operation starting command is sent from an ON command means 1 or the clocking data value exceeds the ON processing time as the compared result to execute time waiting. When the clocking data value exceeds the ON processing time as the compared result of the means 7, the failure of the device A is decided and the means 7 requests the power supply ON error processing of the device A to an error processing means 9. Thus, the failure can be detected within a short time.

Description

TECHNICAL FIELD The present invention relates to a power-on monitoring system, and more particularly to a power-on monitoring system that monitors power-on of each device in an information processing system consisting of a plurality of devices.

BACKGROUND ART Conventionally, in an information processing system composed of a plurality of devices, when the power-on processing time from the time the power is turned on to the end of the power-on operation for each device exceeds a predetermined specified time, that device It was determined that a failure had occurred. In that case, select the input processing time of the device that has the maximum input processing time under normal conditions from among the multiple devices,
This was the specified time mentioned above.

In other words, regardless of the type of equipment, control was performed by comparing it with a fixed time, so it took a long time to recognize a failure for equipment that had a short loading process time under normal conditions, that is, a fast loading operation. There was a drawback that it could take a long time.

OBJECTS OF THE INVENTION An object of the present invention is to provide a power-on monitoring system that can detect failures in a short period of time for devices whose power-on operation is quick.

Composition of the Invention The power-on monitoring system according to the present invention is a power-on monitoring system that monitors the power-on processing time from the power-on of a plurality of devices to the end of the power-on operation, and the power-on monitoring system monitors the power-on processing time from when the power is turned on to the end of the power-on operation of a plurality of devices. a memory means for storing the power-on processing time of the device; a time-measuring means that starts a timing operation when the power is turned on of the device; and a clock value of the time-measuring device based on the normal power-on processing time of the device in the storage means and a means for determining that the device is abnormal when the temperature increases.

Example Hereinafter, the present invention will be explained in detail using the drawings.

FIG. 1 is a block diagram showing the configuration of an embodiment of a power-on monitoring system according to the present invention. In the figure, the power-on monitoring system according to an embodiment of the present invention includes a power-on instruction means 1, a power-on device 2, a clock means 3, and a power-on completion detection means 4.
, writing means 5 , waiting time storage means 6 , timeout detection means 7 , reading means 8 , and error processing means 9
It is composed of:

The power-on instruction means 1 sends a power-on instruction to the device 2 to be turned on,
At the same time, a timing start instruction is sent to the clock means 3. Further, during normal operation, the input instructing means 1 sends an instruction to detect a timeout to the timeout detecting means 7.

The device 2 to be turned on includes a plurality of devices A, B, which turn on the power in response to input of a power-on instruction from the power-on instruction means 1.
C... is. Further, each device sends a power-on completion signal to the power-on completion detection means 4 when the power supply has been successfully turned on.

The clock means 3 starts a timekeeping operation from an initial state in response to the input of a timekeeping start instruction from the input instruction means 1, and sends timekeeping data, which is a timed value, to the writing means 5 and the timeout detection means 7 at any time. .

When the loading completion detection means 4 detects the loading completion signal from the loading device 2, it sends an instruction to write time measurement data to the writing means 5 at the time of initial setting.

Further, during normal operation, the loading completion detection means 4 requests the loading instruction means 1 to instruct the next loading device to be loaded.

The writing means 5 receives a write instruction from the input completion means 4 and instructs the time storage means 6 to store the time measurement data from the clock means 3 for each device.

The time storage means 6 stores the time measurement data inputted from the writing means 5 for each device.

Further, in response to a data request from the reading means 8, the time storage means 6 reads the stored time measurement data for each device, that is, the input processing time, and sends it to the reading means 8.

The timeout detection means 7 starts its operation in response to a timeout detection instruction from the loading instruction means 1, and compares the clock data from the clock means 3 and the loading processing time from the reading means 8 at any time. It is. When the time measurement data becomes larger than the input processing time, an error processing instruction is sent to the error processing means 9. In other words,
There will be a waiting period depending on the input processing time.

The reading means 8 reads from the time storage means 6 the power-on processing time for the device to be powered on, which is instructed by the time-out detecting means 7, and sends it to the time-out detecting means 7.

The error processing means 9 performs power-on error processing for the device to be powered on in response to an error processing instruction from the time-out detection means 7.

Next, the operation of the power-on monitoring system configured as described above will be explained.

■Operation during initial setting First, when the power is turned on, the power-on instruction means 1 sends a power-on instruction to the device A of the devices 2 to be turned on. At the same time, the input instructing means 1 issues a timing start instruction to the clock means 3 to start the timing operation. Then, the device A of the device 2 to be turned on starts a power-on processing operation in response to the power-on instruction from the power-on instruction means 1. When the device A completes the power-on process, it sends a power-on completion signal to the power-on completion detection means 4.

When the loading completion detection means 4 receives the loading completion signal from the loading device 2, it requests the writing means 5 to store the time measurement data. When the writing means 5 receives a request to store the clock data from the loading completion detection means 4, the writing means 5 stores the latest clock data sent from the clock means 3 as the loading processing time in the time storage means 6.
Write to the storage area of input processing time to the device. Further, at this time, the power-on completion detection means 4 issues a storage request to the writing means 5, and also issues a power-on instruction to the power-on instruction means 1 to the next target device 2 to be powered on.

When the power-on instruction means 1 receives a power-on instruction from the power-on completion detection means 4 to the next device to be connected after device A,
Sends a power-on instruction to device B. After that, the same operation as in the case of device A is repeated, and the above operation is repeated for all the devices to be thrown.

In this way, each device A, B,
The normal loading processing time for C... will be stored as an expected value.

■Operation during normal operation First, when the power is turned on, the power-on instruction means 1 sends a power-on instruction to the device A of the devices 2 to be turned on. At the same time, the input instructing means 1 issues a timing start instruction to the clock means 3 to start the timing operation. Further, the input instructing means 1 sends a detection operation start instruction to the timeout detection means 7 to start the timeout detection operation.

When the timeout detection means 7 receives an instruction to start a detection operation from the input instructing means 1, it requests loading processing time data regarding the device A from the reading means 8. When the reading means 8 receives a request for input processing time data from the timeout detection means 7, it reads out the input processing time for the corresponding device, that is, the apparatus, from the time storage means 6 and sends it to the timeout detection means 7.

The timeout detection means 7 compares the input processing time sent from the reading means 8 with the time measurement data sent from the clock means 3 at any time. The comparison between the loading processing time and the clocked data is made when the loading instruction means 1 sends an instruction to start the next detection operation, or as a result of the comparison between the loading processing time and the clocked data, the clocking data is smaller than the loading processing time. This continues until the value becomes larger. In other words, a time wait is performed.

Here, as a result of comparison by the timeout detection means 7, if the clock data value becomes larger than the input processing time, it means that the device A is out of order, and the timeout detection means 7 detects the error processing means 9. Requests A's power-on error handling.

On the other hand, if the device to be turned on outputs a power-on completion signal to the turning-on completion detection means 4 before the time measurement data becomes longer than the turning-on processing time, the device A is determined to be normal. In this case, the power-on completion detection means 4 sends a power-on instruction to the power-on instruction means 1 to turn on the device to be powered on next, that is, the device B.

The input instruction means 1 is connected from the input completion detection means 4 to the device B 7'.
When receiving the 4R input instruction, device B of the input devices 2
Sends power-on instructions to. Thereafter, the same operation as in the case of device A is repeated, and the above operation is repeated for all the devices 2 to be thrown. Therefore, each device can be monitored using the optimal expected value input processing time.

In other words, in the present invention, by checking in advance the normal power-on processing time for each device to be powered on and storing it as an expected value, it is possible to detect failures in a short time for devices that turn on quickly. be. Furthermore, by determining the expected value of the power-on processing time for each device, wasted waiting time can be reduced, and the entire information processing system can be powered on efficiently.

DETAILED DESCRIPTION OF THE INVENTION As described above, the present invention is capable of completing the power-on operation of computers, lighting, etc. in a short time by checking the power-on time of each device to be powered on individually in advance at the time of initial setting and registering that data. When monitoring the power-on of devices that require a long power-on operation such as electronic disks and cooling devices in the same system, it is possible to individually This has the effect of enabling monitoring, reducing unnecessary waiting time, and efficiently powering on the system.
