Description

[Detailed Description of the Invention] (a) Technical Field of the Invention The present invention relates to an improvement in an alarm notification control method for notifying maintenance personnel of alarms generated by exchanges.

(b) Conventional technology and problems Generally, switching equipment is equipped with a failure detection function.
When a failure is detected, an audible or visible alarm is output and a maintenance person is requested to repair the problem. In conventional alarm notification systems, the switching equipment always issues an alarm immediately regardless of the type of fault that has occurred. A maintenance person who comes into contact with the alarm distinguishes a repair method based on the type of alarm or the information indicating the fault type output from the exchange to a typewriter device or the like in parallel with the alarm. For example, if a failure occurs in the central control unit or main memory of an electronic exchange, which may cause a complete suspension of the service of the exchange, immediate repair processing is required, and trunk or subscriber circuits, etc. In cases where the impact on services is limited, such as a failure that occurs during a failure, the warning that is being output is stopped after recording the failure, and repair processing is performed later during periodic maintenance.

As is clear from the above explanation, in conventional alarm notification systems, the alarm was always notified to the maintenance personnel immediately regardless of the type of failure, so the maintenance personnel analyzed the contents of the failure each time and took corrective action. Differentiate the level of urgency. Furthermore, since information indicating the type of fault that is output to a typewriter device or the like is output every time a fault occurs, it is inconvenient to extract only the information regarding the fault to be repaired during periodic maintenance.
Furthermore, once an alarm is stopped, it will not be notified again, so if a maintenance person or the like forgets to record it, there is a risk that the failure will not be repaired and become latent.

(c) Purpose of the Invention The purpose of the present invention is to eliminate the drawbacks of conventional warning notification methods as described above and to realize an alarm notification control method that outputs warnings suitable for repair work by maintenance personnel, etc. .

(d) Structure of the Invention The object of the present invention is to provide an immediate warning registration table 4 in which, in an exchange that generates a plurality of types of alarms, the alarm is registered together with the type of alarm that should be notified immediately or not; Type information of each alarm,
comparing the alarm storage memory 7 that stores information indicating the time of occurrence and whether or not the alarm has been repaired, and the type of alarm generated by the exchange with the type of alarm registered in the immediate alarm registration table; When it is determined that the alarm should be notified immediately, a display signal D for immediately notifying the alarm is output to the alarm device 21, and a predetermined signal S is received from the typewriter device 22 to stop the output display signal. An immediate control circuit 8 that outputs the once-stopped display signal again if a signal R indicating completion of repair of the alarm is not inputted to the write/read control circuit 6 within a time, and an alarm type information and alarm generation when an alarm occurs. The time is stored in the alarm storage memory, information regarding all the alarms stored in the alarm storage memory is extracted and outputted by the output request signal O from the typewriter device 22, and repair completion information is generated when the repair of the alarm is completed. R is input from the typewriter device and stored in the alarm storage memory, and when all alarm type information is repaired, the contents stored in the alarm storage memory are input by inputting an erase signal C from the typewriter device. This is achieved by providing a write/read control circuit 6 that erases all data.

(e) Embodiment of the invention An embodiment of the invention will be described below with reference to the drawings.

The drawing is a diagram showing an alarm notification control method according to an embodiment of the present invention. In the figure, the electronic exchange 1 has four types of alarms corresponding to faults detected in the central control unit, faults detected in the main memory, faults detected in the trunk, and faults detected in the subscriber circuit. It is assumed that information AL1 to AL4 are output. On the other hand, a maintenance person or the like uses the alarm device 21 that outputs a visible or audible alarm, and the alarm type information AL1 to
It is assumed that the computer is equipped with a typewriter device 22 that inputs and outputs AL4 and the like. If the alarm type information AL1 and AL2 require immediate notification when a failure occurs, and the alarm type information AL3 and AL4 do not require immediate notification, the maintenance personnel
Immediate information Y is inputted into the write/read control circuit 3 in correspondence with the alarm type information AL1 and AL2, and non-immediate information N is inputted in correspondence with the alarm type information AL3 and AL4. The write/read control circuit 3 registers immediate information Y and non-immediate information N corresponding to the alarm type information AL1 to AL4 inputted from the typewriter device 22 in the immediate alarm registration table 4. In this state, when a failure first occurs in the central control unit of the electronic exchange 1, the alarm type information AL1 is stored in the buffer register 5. The write/read control circuit 6 extracts the alarm type information AL1 from the buffer register 5, adds the occurrence time T1, and stores it in the alarm storage memory 7.
Store in. In addition, the immediate control circuit 8 provides alarm type information.
Immediately after AL1 is accumulated in the buffer register 5, the instantaneous alarm registration table 4 is referred to, and when it is identified that the instantaneous information Y is registered corresponding to the alarm type information AL1, a display signal D is sent to the alarm device 21. and immediately notify maintenance personnel of the occurrence of a failure.
When a maintenance person or the like transmits an output request signal O from the typewriter device 22 to the write/read control circuit 6, the write/read control circuit 6 extracts the alarm type information AL1 and the occurrence time T1 stored in the alarm storage memory 7. Output to typewriter device 22. Based on the output, a maintenance person or the like immediately performs repair processing on the central control unit of the electronic exchange 1. When a maintenance person or the like who has completed the repair inputs the repair completion information R regarding the alarm type information AL1 from the typewriter device 22 into the write/read control circuit 6, the write/read control circuit 6 corresponds to the alarm type information AL1 in the alarm storage memory 7. Then, the repair completion information R is stored. Next, a fault occurs in the trunk of electronic exchange 1, and the alarm type information AL3 is changed to buffer register 5.
When the alarm type information AL3 is accumulated in the buffer register 5, the write/read control circuit 6 extracts the alarm type information AL3 from the buffer register 5, adds the occurrence time T2, and stores it in the alarm accumulation memory 7. Immediately after the alarm type information AL3 is accumulated in the buffer register 5, the immediate detection control circuit 8 refers to the immediate alarm registration table 4 and stores the alarm type information AL3.
When it is determined that the non-immediate information N is registered in response to the above, the display signal D is not transmitted to the alarm device 21. Next, when a failure occurs in the main memory of the electronic exchange 1 and the alarm type information AL2 is accumulated in the buffer register 5, the write/read control circuit 6 extracts the alarm type information AL2 from the buffer register 5, The occurrence time T3 is added and stored in the alarm storage memory 7. Immediately after the alarm type information AL2 is stored in the buffer register 5, the instantaneous control circuit 8 refers to the instantaneous alarm registration table 4 and checks that the instantaneous information Y is registered corresponding to the alarm type information AL2. When it is identified, a display signal D is transmitted to the alarm device 21, and a maintenance person or the like is immediately notified of the occurrence of the failure. When a maintenance person or the like transmits the display stop signal S from the typewriter device 22 to the immediate control circuit 8, the immediate control circuit 8 stops the display signal D, stops the immediate notification of the alarm device 21, and measures the elapsed time. Start. By the time the elapsed time reaches the predetermined time, the typewriter device 22
If the repair completion information R is not inputted to the write/read control circuit 6 from then on, the immediate notification control circuit 8 transmits the display signal D to the alarm device 21 again, and restarts the immediate notification. Similarly to the above, a maintenance person or the like transmits the output request signal O from the typewriter device 22 to the write/read control circuit 6,
All information stored in the alarm storage memory 7, that is, alarm type information AL1, AL3, and AL2, respective occurrence times T1 to T3, and alarm type information AL
By causing the typewriter device 22 to output repair completion information R, etc. corresponding to No. 1, the main storage device of the electronic exchange 1 is immediately repaired. When a maintenance person or the like who has completed the repair inputs the repair completion information R regarding the alarm type information AL2 from the typewriter device 22 into the write/read control circuit 6, the write/read control circuit 6 corresponds to the alarm type information AL2 in the alarm storage memory 7. Then, the repair completion information R is stored. Furthermore, when a fault occurs in the trunk subscriber circuit of the electronic exchange 1 and the alarm type information AL4 is accumulated in the buffer register 5,
The write/read control circuit 6 extracts the alarm type information AL4 from the buffer register 5, adds the occurrence time T4, and stores it in the alarm storage memory 7. Further, as soon as the alarm type information AL4 is accumulated in the buffer register 5, the immediate detection control circuit 8 immediately controls the immediate alarm registration table 4.
When it is determined that the non-immediate information N is registered corresponding to the alarm type information AL4, the display signal D is not transmitted to the alarm device 21. Eventually, it is time to perform regular maintenance, and when a maintenance person or the like transmits an output request signal O to the write/read control circuit 6, the write/read control circuit 6 reads all the alarm type information AL1 to AL4 stored in the alarm storage memory 7. and related occurrence times T1 to T4 and repair completion information R are output to the typewriter device 22. The maintenance person obtains the alarm type information that occurred at occurrence times T1 and T3 from the output information.
AL1 and AL2 have been repaired, and the occurrence time T
Knowing that the alarm type information AL3 and AL4 that occurred at times 2 and T4 are unprocessed, the trunk and subscriber circuits are repaired. When all the alarm type information AL1 to AL4 have been repaired, the maintenance person can read the write/read control circuit 6 from the typewriter device 22.
By inputting the erase signal C to , the write/read control circuit 6 is caused to erase all the contents stored in the alarm storage memory 7. Note that when the write/read control circuit 6 detects that there is no more storage area for new alarm type information AL1 to AL4 in the alarm storage memory 7, it outputs a message to that effect to the typewriter device 22 and sends a message to the maintenance personnel etc. It causes the contents of the alarm storage memory 7 to be output to an external storage device (not shown), or executes measures such as erasing alarm type information AL1 to AL4 that are no longer needed.

As is clear from the above explanation, according to the present embodiment, the maintenance personnel etc. immediately notify the alarm device 21 of only the alarm type information AL1 and AL2 that require emergency repair, and the other alarm type information AL3 and AL4 are periodically notified. By extracting the stored contents of the alarm storage memory 7 during maintenance or the like, it becomes possible to easily identify the type of fault that should be dealt with. Furthermore, if the immediate notification is once stopped and repair is not performed within a predetermined time, the immediate notification will be performed again to prevent the failure from becoming latent.

Note that the drawing is merely one embodiment of the present invention, and for example, the alarm type information is not limited to the four types shown, and many other modifications may be considered; The effects of the present invention remain unchanged.
Further, the means for realizing the present invention is not limited to what is shown in the drawings, and many other modifications may be considered, but the effects of the present invention will not change in any case. Furthermore, it goes without saying that the switching equipment to which the present invention is applied is not limited to electronic switching equipment.

(f) Effects of the invention As described above, according to the present invention, in the switching equipment,
It becomes possible to realize an alarm notification control method that outputs an alarm suitable for repair work by maintenance personnel, etc., promoting rationalization of maintenance work and improving the reliability of the exchange.
