Abstract

PURPOSE:To shorten the trouble-shooting time by providing a time counting function which is counted up only during operation of a main device and a time counting function which can be adjusted by a user and detecting the sum total of operation time of the main device and the system operation time at the time of the occurrence of abnormality or the like in the main device. CONSTITUTION:A log information gathering circuit 50 is started when log information is required by a factor at the time of the occurrence of abnormality in a main device 1, and this circuit 50 gathers information corresponding to log of the main device. Gathered log information is transferred to a log generating circuit 60. The log generating circuit 60 gets the latest clock information from time counting circuits 20 and 30 to form an information format to be stored in a log storage file 80. A log write control circuit 70 performs the processing to store said data in a log storage file 80. Contents of the log storage file 80 are checked at the time of the occurrence of abnormality to locate trouble in a short time.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention is based on a monitoring device connected to a main unit, and uses a logging method, which is one of its functions, to record a log when an error or the like occurs. (Regarding time information as a public report.)

In today's highly information-oriented society, if the main unit, especially the converter main unit, communication control processing unit, etc. becomes unable to provide normal functions due to a failure or other cause, it will affect not only corporate activities but also daily social functions. The impact is becoming greater. This trend is going to increase rapidly in the future.

For this reason, once a failure occurs in the main unit, etc., the cause should be determined as quickly as possible based on the records stored in the monitoring device connected to the main unit, and the faulty part should be repaired. is necessary.

Furthermore, based on the records stored in the monitoring device connected to the main unit, we can identify signs of serious failures before they occur, and take appropriate measures in advance to prevent system failures due to failures. Technology to prevent this is needed.

[Conventional technology]

The conventional method has only one internal timekeeping function, and depending on its control method, either the main unit operating time (for example, Japan Standard Time) or timekeeping information unique to the device (for example, total operating time) is recorded. Therefore, by simply looking at the recorded log information, it was only possible to obtain information about either the trend of error occurrence over time or the relationship between the time of day's work and the status of error occurrence.

[Problem that the invention seeks to solve]

Traditional logging methods require only one timekeeping circuit in the monitoring device. Depending on the control method of the monitoring device, the clock circuit can tell whether it is the main unit operating time (for example, Japan Standard Time) or
Or, just in case you want to manage either one of the device's unique timing information (for example, total operating time). Information on the above-mentioned timekeeping circuit was used as the timekeeping information added to the log information.

Ninth, just by looking at the recorded log information, it is only possible to obtain information about either the tendency of error occurrence due to changes over time or the relationship between the time of daily work and error occurrence. It was not possible to determine the tendency of failure occurrence, that is, whether the failures were due to aging or concentrated in a specific time period, which hindered the ability to search for failure locations and predict the severity of failures. .

[Effect]

Timing circuit (20) of the present invention #-tt source control circuit [10]
The operating time of the device is measured by performing a timing operation only while the power ready signal (120) supplied from the power supply ready signal (120) is valid, and the timing circuit (30) can change the timing information by the adjustment circuit (40). For example, the log collection circuit (50) has a function of collecting log information with the main device (1), and has a function of transmitting the information to the log formation circuit (60). and the log forming circuit (
60) is the information transferred from the log collection circuit (50), the latest clock information of the clock circuit (20), and the clock circuit (30)
The information to be stored in the log storage file (80) is formed based on the latest clock information of , the information is transferred to the log write control circuit (70), and the log information is stored in the log storage file (80).

As a result, the operating time information of the device and the user's operating time are recorded as log information.

The log collection circuit 50 is activated when a log becomes necessary due to an abnormality occurring in the main unit 1, etc., and collects information worthy of logging from among various information in the main unit. This collected log information is transferred to the log forming circuit 60. By transferring information from the log collection circuit 50 to the log forming circuit 60, the latest clock information is acquired from the clock circuit 20 and the clock circuit 30, and is combined with the log information previously transferred from the log collection circuit 50. An information format to be stored in the log storage 7 isle 80 is formed, and the data is transferred to the log write control circuit 70. The log write control circuit 70 performs processing to store the data in the log storage file 80.

According to this embodiment, when an abnormality or the like occurs in the main unit, a system operator or a maintenance person can check the contents of the log storage file 80 to determine the total operation of the main unit at the time when the abnormal condition occurred. It is possible to know the time (lifetime) and the normal time during system operation, and since these are useful data for fault location detection, the time for fault location search can be shortened and a serious failure has not yet occurred. However, it is possible to quickly remove defective parts that, if left untreated, may cause failures in the future.

[Effect of invention (device)]

According to the present invention, when an abnormality or the like occurs in the main unit, a system operator or a maintenance person, etc. can subsequently inspect the contents of the log storage file 80, thereby detecting the abnormal state and the total operation of the main unit at nine points in time. It is possible to know both the time and the normal time during system operation, and based on the record of the occurrence of failures over time, it is possible to shorten the time required to search for the failure location, and even if a major failure has not yet occurred, it is possible to If left in place, it is possible to quickly remove defective parts that may cause failures in the future.
