Abstract

PURPOSE:To make an efficient fault diagnosis by restarting a diagnostic program from the interrupted state. CONSTITUTION:A diagnostic result storage means 1 stores the result of diagnosis at the time of interrupting a diagnostic program. In the means 1, for example, information indicating whether or not a diagnostic program is interrupted and the result of the diagnosis up to the interruption are stored. A discrimination means 2 discriminates whether or not the interrupted diagnostic program is existent at the time of executing the diagnostic program. A restarting means 3 restarts the diagnostic program from the interrupted state based on the diagnostic result at the time of interruption when the diagnostic program interrupted by the means 2 is judged to be existed. Thus, the waste processing time due to the execution of the diagnostic program once more from the start can be eliminated, making an efficient fault diagnosis.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a failure diagnosing system for diagnosing a failure of a device connected to an electronic exchange system or the like and confirming its normality.

[0002]

2. Description of the Related Art An electronic exchange system or the like is provided with a diagnostic program in order to improve the reliability of the system. This diagnostic program is automatically started when a failure occurs, is specified by the failure point, and is regularly started by a command or a timer for confirming the normality of the system.

[0003]

In general, the diagnostic program is a low-priority task so as not to interfere with the online processing operation. Therefore, if the call processing volume increases during execution of the diagnostic program, for example, The diagnostic program will be interrupted. In such a case, the conventional diagnosis method does not save the diagnosis results during execution, so when restarting the diagnosis, it is necessary to execute the diagnosis program again from the beginning, and it takes time for the failure diagnosis. was there.

An object of the present invention is to enable the program to be resumed from the interrupted state when the diagnostic program is interrupted.

[0005]

FIG. 1 is a block diagram showing the principle of the present invention. In the figure, the diagnostic result storage means 1
Stores the diagnosis result up to that point when the diagnostic program is interrupted. The diagnostic result storage means 1 stores, for example, information indicating whether or not the diagnostic program has been interrupted and the diagnostic result up to the time of the interrupt.

The determination means 2 determines whether or not there is a suspended diagnostic program when the diagnostic program is executed. When the determination unit 2 determines that the interrupted diagnostic program exists, the restart unit 3 restarts the diagnostic program from the interrupted state based on the diagnosis result at the time of the interrupt.

[0007]

In the present invention, when the diagnostic program is interrupted,
The diagnosis result up to that time is stored in the diagnosis result storage unit 1.

Then, when the diagnostic program is executed next time, it is judged whether or not the interrupted diagnostic program exists, and when the interrupted diagnostic program exists,
The diagnostic program is restarted from the suspended state based on the diagnostic result at the time of suspension.

Therefore, when the interrupted diagnostic program is re-executed, the program can be restarted from the interrupted state, so that it is possible to eliminate the waste of processing time caused by executing the diagnostic program from the beginning as in the conventional case. ,
Fault diagnosis can be performed efficiently.

[0010]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 2 is a diagram showing a configuration of a diagnosis unit that diagnoses whether or not there is a failure in an electronic exchange and a device connected to the exchange.

The automatic diagnosis control unit 11 activates the diagnosis management unit 14 in order to identify a failure location when a failure occurs. The command diagnosis control unit 12 issues a command to activate the diagnosis management unit 14 to execute the diagnosis, and the regular diagnosis control unit 13 has a timer and has the diagnosis management unit 14 at regular intervals.
To start the diagnostics.

The diagnosis management unit 14 is provided for each diagnosis control unit 1 described above.
1, 12 and 13 are activated, and the diagnosis control unit 15 is instructed to execute the diagnosis. The diagnostic execution unit 15 reads the test data from the test data storage unit 16 and executes various diagnostic programs. When the diagnostic program is interrupted during the diagnostic execution, the diagnostic results and the diagnostics up to that point are interrupted. The information (diagnosis restart flag) indicating that the test has been performed is stored in the test result storage unit 17.

Next, the operation of the diagnostic execution unit 15 will be described with reference to the flowchart of FIG. When the diagnosis execution unit 15 is instructed to execute the diagnosis, the diagnosis execution unit 15 checks whether or not the diagnosis restart flag is set, and determines whether the current start is the restart start (FIG. 3, S1). ). Here, the diagnosis restart flag is a flag indicating whether or not the process is interrupted during the execution of the diagnosis, and when the flag is set, it indicates that the diagnosis is interrupted.

If it is determined in step S1 that the system is not restarted, the name of the device to be diagnosed is stored in the test result storage unit 1.
7 is stored in the diagnostic device name area (S2), the diagnostic test No. to be executed is initialized, and the test No. is stored in the diagnostic test No storage area of the test result storage unit 17 (S3).

Next, the test data corresponding to the device name to be diagnosed and the diagnostic test No. is read from the test data storage unit 16, edited (S4), and the test is executed (S).
5). Then, the test result is stored in the test result storage unit 17 (S6), and the diagnostic test No for which the diagnosis is completed is stored in the diagnostic test No storage area 19 (S7). Further, it is determined whether the test is the final test (S8).

If it is not the final test, it is then determined whether or not a cause of interruption of diagnosis has occurred (S9). If no cause of interruption has occurred, the process returns to step S4 and the next data is stored in the test data storage unit 16. Read the test data and run the next diagnostic test.

If an interruption factor is generated due to an increase in call processing amount or the like in the determination in step S9, the diagnosis restart flag is turned on (S10), the monitoring timer is initialized, and then the diagnosis restart monitoring program is started. (S11), the diagnosis is interrupted.

The diagnostic restart monitoring program is a program that is started every minute, and when the program is started,
First, it is determined whether or not the monitoring timer time has passed 5 minutes (S12). If the time of the monitoring timer is not more than 5 minutes, the minute digit of the monitoring timer is incremented by "1" (S
13) Then, the process ends.

If it is determined in step S12 that the time of the monitoring timer is 5 minutes or more, it means that 5 minutes or more have passed since the diagnosis was interrupted. In this case, the diagnosis executing section 15 is activated again (S14). ), The activation of the diagnostic restart monitoring program is stopped (S15).

When the diagnosis execution unit 15 is started, the diagnosis restart flag is checked in the above-mentioned step S1 to judge whether or not it is started by restarting. In this case, since the diagnosis execution unit 15 is activated after the diagnosis is interrupted during the execution of the diagnosis test, the determination in step S1 as to whether or not the restart flag is set is YES and the process proceeds to step S16. Then, the name of the device for which the previous diagnosis was interrupted is read from the diagnostic device name area, and it is determined whether the device name is the same as the device to be diagnosed this time.

If the device names are the same, the diagnosis restart flag is turned off, and the process proceeds to step S4 described above to restart the diagnosis.
In the above embodiment, when the diagnosis is interrupted, the device name under diagnosis, the diagnostic test No and the test result are saved, and the diagnosis restart flag indicating that the process is interrupted during the diagnosis is set. When the diagnosis is executed, the diagnosis can be restarted from the suspended state based on the information.

As a result, when the interrupted diagnostic program is executed again as in the conventional case, it is not necessary to execute the diagnostic program from the beginning, so that the failure diagnosis can be efficiently performed.

The present invention can be applied not only to the exchange system described in the embodiment but also to a computer system, a communication system, etc. having a failure diagnosis program.

[0024]

According to the present invention, when the interrupted diagnostic program is executed, the diagnostic program can be restarted from the interrupted state, so that the failure diagnosis can be efficiently performed.
