DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an alarm optimizing device which receives a failure detection signal output from a device such as a communication system, determines the content of a failure, and outputs the result.

In a communication system such as a multiplexing device,
When a fault occurs in a line, an internal LSI device, or the like, a fault detection signal indicating fault content such as a fault location and a fault type is output. Then, the alarm optimizing device that inputs the failure point detection signal outputs the details of the failure, the degree of the failure, the number of occurrences, and the like to a display, a printer, or the like. In addition, the occurrence of a failure is notified by turning on a warning lamp or sounding a warning buzzer.

[0003] Such an alarm optimizing device increases the number of alarm items and the number of alarms as the scale of the communication system increases. A large number of fault detection signals including a secondary fault detection signal output following the fault are output simultaneously. Therefore, it is desired to develop an alarm optimizing device that can automatically detect a truly important fault from a large number of fault detection signals.

In the figure, reference numeral 110 denotes a device, such as a multiplexing device of a communication system, which detects a fault location and fault content of the device and outputs a fault detection signal.

Reference numeral 124 denotes an alarm output signal generation unit that outputs an alarm output signal indicating the content and level of the failure to the alarm output device 130.

Reference numeral 130 denotes an alarm output device, such as a display, a printer, a warning, and a warning buzzer. The operation of the conventional alarm optimization device will be described.

When a fault occurs in the device 110, the fault monitoring unit 111 detects the fault and generates a fault detection signal. The failure detection signal output unit 112 outputs a failure detection signal. The alarm optimization device 120 receives a failure detection signal from the device 110. The failure content determination unit 122 determines the content of the failure based on information indicating the content of the failure attached to the failure detection signal, and the failure degree determination unit 123 determines the importance of the failure based on the failure content. For example, since the failure of the input line affects all of the output lines, it is determined that the degree of importance is high, and the degree of the failure is determined by the influence according to the failure location, the failure type, and the like.

[0010] Then, an alarm output signal indicating the location of the failure and the degree of importance is generated and output to the alarm output device 130. The alarm output device 130 includes a display, a printer, a warning light, an alarm buzzer, and the like. In addition, the warning light flashes and the buzzer sounds as necessary.

[0011]

In the conventional alarm optimizing device, the degree of a fault such as a severe fault or a minor fault displayed together with a fault location of a line or a channel device and the type of the fault is determined by designing the alarm optimizing device. It is something that is sometimes determined. Therefore, the failure determined as a severe failure at the time of design,
Even if it occurred momentarily for some reason and immediately recovered and had no effect on the system, it was output as the occurrence of a severe failure, and abnormal processing of the severe failure was performed.

Also, in the case of an alarm that repeatedly occurs and recovers within a certain period of time, an alarm output signal indicating generation and recovery is generated, and all the generated alarm output signals are output to the alarm output device. Was. In such a case, the information is repeatedly output to the printer for a long time to repeat the generation and recovery of the alarm. Or, if a fault occurs on the input line, the output line also becomes abnormal. Therefore, even if no fault has actually occurred on the output line, a secondary fault detection signal indicating an output line error is output to distinguish it from the main fault. It was difficult to do.

FIG. 2 is a diagram for explaining the operation of the basic configuration of the present invention.
FIG. 2A is an explanatory diagram of the operation of the basic configuration (a) of the present invention.
FIG. 2B is an explanatory diagram of the operation of the basic configuration (b) of the present invention.

In FIG. 2A, (1) indicates a failure detection signal, and (2) indicates an alarm level signal. In (1) and (2), the horizontal axis is the time axis and the vertical axis is the signal level. (2) shows a case where there are three signal levels as an example.
When the duration of the failure detection signal in (1) is t1, the alarm level signal is set to level 1, and when the duration of the failure detection signal in (1) is t2, the alarm level signal is set to level 2.
When the duration of the fault detection signal in (1) is t3, the alarm level signal is set to level 3.

The operation of the basic configuration of the present invention shown in FIG. 1A will be described with reference to FIG. Upon detecting a failure in the device 1, the failure monitoring unit 2 generates a failure detection signal indicating the content of the failure, and the failure detection signal output unit 3 outputs a failure detection signal.
Then, the alarm optimizing device 10 receives the failure detection signal output from the device 1.

In the alarm optimizing device 10, the fault content judging unit 20 judges the fault content of the input fault detection signal and, for example, an alarm holding unit 21 determined for each fault content (fault location, fault type, etc.). A failure detection signal (for example, an H-level signal) is stored in the storage area.

The alarm length determining section 22 determines the duration of the input fault detection signal. Failure detection signal of FIG.
In the case of (1), the duration of the alarm A is t1, the alarm B
Is t2 and the duration of alarm C is t3. If the duration of the failure detection signal does not exceed t1, an alarm level signal of level 1 is generated, and if the duration is greater than t1 and does not exceed t3, an alarm level signal of level 2 is generated, and the duration is t3. If it is larger, it is set in advance to generate a level 3 alarm level signal. And an alarm level signal generator 2
Reference numeral 3 generates an alarm level signal having a level corresponding to the duration of the failure detection signal determined by the alarm length determination unit 22. In the case of FIG. 2A, a level 1 alarm level signal is generated for alarm A, a level 2 alarm level signal is generated for alarm B, and a level 3 alarm level signal is generated for alarm C. Generate a level signal.

The alarm output signal generator 24 generates an alarm output signal to be displayed on the alarm output device 30 for each level of the alarm level signal. For example, for an alarm level signal of the alarm A having a short duration, an alarm output signal indicating a minor fault is generated. Alarm B of medium duration generates an alarm output signal to indicate a medium fault. For an alarm C having a long duration, an alarm level signal is generated to indicate that the degree of the fault is serious.

The alarm output device 30 operates according to the alarm level signal generated by the alarm level signal generator 23.
Each processing is performed. For example, alarm A is displayed as a minor fault, alarm B is displayed as a medium fault, and alarm C is displayed as a high-priority fault. Further, if necessary, a warning or the like is turned on for the alarm A, a warning or buzzer sounds for the alarm B with the warning or the like turned on, and a warning or buzzer is sounded for the alarm C. A signal for instructing the disconnection of a fault may be output to the device 1 so as to perform a process of automatically separating the fault location in the device 1.

FIG. 2B is a diagram for explaining the operation of the basic configuration (b) of the present invention. In FIG. 2B, (3) is an alarm A, which is a fault detection signal of the fault content A. (4) is an alarm B, which is a fault detection signal of the fault content B, which is fault detection information that has been generated secondarily based on the generation of the fault detection signal A. For example, it is assumed that the output line B is connected to the input line A. At this time, if a failure occurs in the input line A, the output of the output line B also becomes abnormal. Therefore, even if B is not out of order, a fault detection signal indicating a fault in the output line B is generated as a fault detection signal indicating a fault in the input line A, and a fault detection signal indicating a fault in the input line A is generated. ), And stored in the alarm holding unit 21 as alarm B (failure detection information of the output line B).

Reference numeral 40 denotes a display example of the display suppression mode.
The alarm A, which is the main fault, is output, but the alarm B, which is secondary fault detection information generated with the alarm A, is not displayed and output.

Reference numeral 41 denotes a display example in the case where the secondary fault is displayed and output while being distinguished from the main fault (for example, color-coded). The alarm of line A, which is the main fault, is displayed in red,
Alarm B of line B, which is a secondary fault, is displayed in yellow.

Next, the operation of the basic configuration of the present invention shown in FIG. 1B will be described with reference to FIG. It is assumed that a failure has occurred in the input line A in the device 1. The fault monitoring unit 2 generates a fault detection signal of A. Further, when the input line A fails, the output of the line B connected thereto also becomes abnormal. Therefore, the failure monitoring unit 2 generates failure detection information of the output line B. The failure detection signal output unit 3 outputs the failure detection signal generated by the failure monitoring unit 2.

The alarm optimizing device 10 inputs a failure detection signal, and the failure content determination unit 20 determines a failure detection signal of the input line A and a failure detection signal of the output line B. Then, they are stored in the alarm A storage area and the alarm B storage area of the alarm holding unit 21, respectively.

The alarm collection unit 26 is provided with the alarm holding unit 21
Is periodically scanned to obtain alarms A and B. Then, the alarm output signal generator 24 generates alarm output signals of the alarm A and the alarm B. At this time, the secondary failure determination unit 35 refers to the secondary failure information table 28 and determines that the alarm B is the secondary failure information of the alarm A. Then, the alarm output editing unit 36 generates an alarm output signal that can distinguish between the alarm A and the alarm B. For example, when the mode is specified so that the secondary failure detection signal (alarm B) is not output, only the alarm A is output to a display, a printer or the like, and the alarm B is not output. Or,
If the mode of displaying and displaying the main fault and the secondary fault in different colors is specified, the alarm A which is the main fault
Is displayed on the display in red, and the alarm B is displayed and output in yellow.

It should be noted that the alarm optimizing device may be constituted only by the basic configuration (a) and the basic configuration (b) of the present invention, or may be used as an alarm optimizing device using both of them. Further, the level setting method (setting of the number of levels, duration, etc.) of the basic configuration of the present invention can be variously changed, and the display method of the alarm output device is not limited to the above method. Furthermore, the basic configuration of the present invention
The display output mode of (b) may be plurally provided in the same device or may be independent. Further, the mode setting method is not limited to the above method.

According to the present invention, the importance of the failure detection signal can be automatically set according to the duration, so that a serious failure and a minor failure can be reliably distinguished and displayed. Further, different output methods can be easily performed according to the degree of the failure. Further, according to the present invention, since the main fault and the secondary fault can be output separately, it is possible to easily determine the main fault that has actually failed.

According to the present invention, the importance of an alarm can be determined based on the duration of a failure detection signal, and a display output and a warning method according to the importance can be flexibly selected. In addition, the relationship between the duration and the degree of failure can be freely changed by setting the duration, and the importance of the failure can be set according to the device, or the failure duration and the importance of the failure can be empirically determined even with the same device. Settings can be changed.

In addition, since a location where an actual failure has occurred and secondary failure information which has not actually failed but has occurred due to the failure can be output separately, the main failure can be easily determined. It becomes possible.
