DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an alarm processing method in a telecommunication device, and more particularly, to a method in which a failure occurs in any of a plurality of monitored parts whose failure is monitored at predetermined time intervals by an alarm signal. The present invention relates to an alarm processing method for notifying an alarm to a user.

[0002]

2. Description of the Related Art As a telecommunication device, for example, a transmission device is known. The transmission device is provided with a plurality of function packages. In each of these function packages, a plurality of function processing units for further realizing a plurality of functions are formed. These function processing units monitor the status change as a plurality of monitored units (hereinafter also referred to as alarm points) in the transmission device, and when a failure occurs, a higher-level device connected to the transmission device. Alarm notification processing. The monitoring of the status change of each monitored unit is performed by the processing unit provided in the transmission device, for example, when one of the monitored units receives
An alarm signal sent at intervals of seconds is monitored, and a change in the state of the monitored part, that is, generation of an alarm is monitored by the alarm signal. When an alarm signal indicating that a failure has occurred is generated in any of the monitored units, an alarm notification process for notifying the host device of the occurrence of the failure has been performed.

In the transmission apparatus as described above, conventionally, FIG.
Is provided. FIG.
1 is a conceptual diagram of a conventional alarm notification device.

[0004] In FIG. 8, a conventional alarm processor 101 is shown.
Is composed of a RAM 102 as a first storage unit, a register 103 as a second storage unit, and a processing unit 104 that monitors an alarm signal and performs an alarm notification process to a higher-level device when a failure occurs. Have been. The RAM 102 stores mask data D1, alarm data D2, and ground data D3.
And the notification data D4 is stored and held by the number corresponding to the plurality of monitored units. The mask data D1 is
For example, the data is set for each monitored unit when the monitored unit is not set as a failure monitoring target. For example, when the mask data D1 is represented by a binary number, and when a failure is not monitored, data of "0" is used to distinguish whether the monitored part is a failure monitoring target. When a failure is to be monitored, no mask processing is performed. Then, for example, when an alarm signal “1” indicating that a failure has occurred is sent from the monitored unit,
If the failure of the monitored part is to be monitored, the sent alarm signal is allowed to go to the next processing without being masked. If the failure is not to be monitored, the masking data D1 "0" is used. Are excluded from the fault monitoring. The ground data D3 is used as a ground output for indicating the occurrence of a failure provided in the transmission device, for example, as control data for lighting a lamp. Notification data D
Reference numeral 4 denotes data indicating whether or not a failure notification to the above-described higher-level device is to be performed. For example, in the case where a secondary fault of a fault that has already occurred in another monitored unit is not notified to the upper device to the upper device, it is determined whether or not to notify the higher device using the notification data D4. . These data D1, D
3 and D4, one piece of data corresponds to each monitored part. The above-mentioned alarm data D2 is used as an alarm signal. For example, if the value is “1”, it indicates that a failure has occurred, and if the value is “0”, it indicates that a normal state in which no failure has occurred. Show.

In general, when monitoring a failure in each monitored part using the alarm data D2, it is often the case that not only the occurrence of a failure but also a time-series change from the occurrence of the failure to its recovery is monitored. In performing such monitoring, a plurality of alarm data D2 are stored for one monitored unit, and a change in the time series of the failure is monitored by a change in the value of each alarm data D2. That is, in the conventional alarm processing apparatus 101, for example, when monitoring a time-series change of a failure for three seconds, the RAM 1
02 stores three pieces of alarm data D2 for one monitored part. The three pieces of alarm data D2 indicate a time series change of the failure for three seconds, at time T, time T + 1 seconds, and time T + 2 seconds for the monitored unit. Hereinafter, one time is referred to as “one generation”. That is, in the case described above, the three alarm data D2 indicate alarm data of three generations.

[0008] In the alarm processing apparatus 101 shown in FIG. 8, the alarm processing for a plurality of monitored parts is performed as described below. That is, first, for one monitored part among the plurality of monitored parts, the corresponding mask data D
1 is transferred from the RAM 102 to the register 103. Then, the processing unit 104 performs an alarm mask process using the mask data D1 transferred to the register 103. next,
The alarm processing device 101 transfers, from the RAM 102 to the register 103, three pieces of alarm data D2, that is, information indicating a time-series change of three generations of faults. The processing unit 104 uses the three alarm data D2 transferred to the register 103 to monitor a time-series change in the failure of the monitored unit. Next, the alarm processing device 101 transfers the ground data D3 from the RAM 102 to the register 103. The processing unit 104 includes the register 10
Then, a geo-processing is performed using the geo-data transferred to step 3. Next, the alarm processing device 101 stores the notification data D4 in the RAM 1
02 to the register 103. The processing unit 104
Using the notification data D4 transferred to the register 103, an alarm notification process to the host device has been performed. Then, after the above-described series of processing is performed on one monitored part, the same processing is repeated for all monitored parts.

[0007]

However, in the alarm processing method performed by the conventional alarm processing apparatus 101,
When performing alarm processing on one monitored unit, the RAM 102
In order to transfer the data D1 to D4 to the register 103, the number of accesses to the RAM 102 has been large. Further, in order to transfer the alarm data D2 to the register 103, the RAM 102
From the register 103 to the register 103 were repeated. For this reason, since the access operation to the RAM 102 is performed a plurality of times for each monitored unit, if the number of monitored units increases due to a change in the specifications of the transmission device or the like, the RAM 1
02, the number of accesses has increased, and this has had an adverse effect on the alarm processing time of all monitored units.

[0008]

In this case, the processing unit 4 performs various processes such as an alarm notification process to a higher-level device and a ground process. RAM2
Stores an information management table 21 and definition data 22, 23, 24, and 25 for importance determination for determining the importance of a failure that has occurred in each monitored unit.

In FIG. 2, one information management table 21 is provided in the RAM 2 for each of a plurality of packages provided in the transmission device. In this embodiment, one of the information management tables 21 will be described. The information management table 21 includes PKG type information indicating the type of the package, system information indicating the type of the package, the number of alarms (D01) indicating the number of monitored units included in the package,
It is configured by alarm information (1) to (n) of a plurality of monitored units (1) to (n) in the package. Each piece of information in the information management table 21 is represented by a 32-bit binary number. The alarm information (1),..., (N) has the same data structure. Warning information using FIG. 3 (1)
Will be described.

In FIG. 3, the data D10 of the alarm information (1) in the information management table 21 includes notification data D11, ground data D12, mask data D13, and alarm generation management data D14.
have. Each data has an 8-bit length, and the alarm generation management data D14 is arranged at the position of 0 to 7 bits of the data D10, and thereafter, the mask data D13, the ground data D12, the notification data D
11 is arranged. Notification data D11, ground data D12,
The mask data D13 has the same configuration as the notification data D4, the ground data D3, and the mask data D1 in FIG. In the alarm generation management data D14, each bit represents an alarm signal of one generation, that is, an alarm signal every second. That is,
The alarm generation management data D14 can hold an alarm signal seven generations (7 seconds) before the current alarm signal of the corresponding monitored unit.

In FIG. 4, definition data 2 for importance determination
Each of 2 to 25 is represented by an 8-bit binary number. The importance level definition data 22 to 25 include each bit of the alarm generation management data D14 and the determination data “00000”.
111 "is used to determine the importance of a fault that has occurred in the monitored part based on the result of the logical product operation. That is, it is determined which one of the importance determination data 22 to 25 described below corresponds to the result of the logical product operation of each bit of the alarm generation management data D14 and the determination data "00000111". The significance level definition data 22 is represented by “00000000”, and indicates that no alarm has been detected for 8 seconds and no failure has occurred in the corresponding monitored unit. In this case, the importance of the failure is determined to be normal. The definition data 23 for importance determination is “0
0000011 ". Since the lower two bits of the definition data 23 for importance determination are “1”, it means that the alarm signal “1” has been input continuously for two seconds. That is, two seconds have passed since the failure occurred in the corresponding monitored unit. In this case, the degree of importance of the failure is determined to be “occurrence” indicating that the failure continues to occur. The definition data 24 for judging importance is
"00000010. In the definition data 24 for importance determination, only the second bit from the lower order is" 1 ".
It has become. This means that a failure has occurred in the monitored unit one second before and no failure has occurred at present.
In this case, the importance of the fault is determined to be “instantaneous” indicating that the fault has occurred instantaneously. The significance determination definition data 24 is represented by “00000010. In the significance determination definition data 25, only the second and third bits from the lower order are“ 1 ”. This means that a failure has occurred in the monitored unit two seconds before and no failure has occurred at present. In this case, the degree of importance of the failure is determined to be "recovery" indicating that the failure has occurred and recovered. The above-described failure importance determination is used to determine the state of failures of three generations. However, according to the present invention, the number of generations for judging the state of a fault is not limited to three generations.
By increasing each definition data shown in,
It is possible to determine the importance of various generations of faults.

Next, an alarm processing operation of the above-described alarm processing device 1 will be described.

At step F1 in FIG. 5, the definition data for importance determination 22 to 25 stored in the RAM 2 is transferred to the register 3.

Next, in step F2, a package for alarm processing is set. That is, with reference to the PKG type information of the information management table 21 shown in FIG.
Set. Next, in Step F3, Step F2
The data D10 of the alarm information (1) in the information management table 21 set in the step (1) is transferred to the register 3. At this time, the data D10 transferred to the register 3 includes the notification data D11, the ground data D12, the mask data D13, and the alarm generation management data D14 as shown in FIG.
, And four types of data transfer can be performed in one transfer operation to the register 3.

Next, in step F4, the value of each bit of the alarm generation management data D14 of the data D10 transferred to the register 3 is shifted by one bit to the left. At this time, the value of the highest bit of the alarm generation management data D14 is deleted when shifting the value of each bit. As shown in FIG.
By the processing of step F4, the alarm generation management data D14
The data at the least significant bit position is empty data. Next, in step F5, the latest alarm signal value of the monitored unit is written to the least significant bit of the alarm generation management data D14. Next, in step F6, mask processing is performed on the alarm generation management data D14. In the present embodiment, the mask data D13 is set to "00000000" for a monitored part that is not targeted for failure monitoring. If the monitored part is not to be monitored for a fault, the least significant bit of the alarm generation management data D14 is set to the mask data D13.
Is masked by the least significant bit. Such a mask process can be performed by a conventionally known process.

Next, in step F7, the importance of the masked alarm generation management data D14 is determined. In the process of step F7, the process shown in FIG. 7 is performed.

In step F61 of FIG. 7, it is determined whether or not the masked alarm generation management data D14 indicates "normal" in which no failure has occurred. This judgment identifies the masked alarm generation management data D14, and if the data is "00000000", it is determined to be normal. If it is determined that the alarm generation management data D14 is normal, the importance level determination processing is terminated, and the alarm generation management data D14 is terminated.
If it is determined that 14 is not normal, the process proceeds to step 61.

Next, in step F62, it is determined whether or not the importance of the fault indicates the above-mentioned "occurrence". This determination is performed by performing an AND operation on each bit of the alarm generation management data D14 and the determination data "00000111", and confirming whether the resulting bit matches the importance determination definition data 23 indicating "occurrence". It depends on whether or not. Step F6
If YES in step 2, the process moves to step F621.
In step F621, it is determined that the importance of the alarm generation management data D14 is "occurrence", and the importance determination processing ends. This determination processing is performed, for example, by setting a flag indicating the importance of the alarm generation management data D14 to the tooth processing unit
And can be performed by using the flag. If NO in step F62, the process proceeds to step F63.

In step F63, it is determined whether or not the importance of the failure indicates the above-mentioned "recovery". This decision
Each bit of the alarm generation management data D14 and the determination data "0"
0000111 "and the resulting bit is the significance determination definition data 25 indicating" recovery ".
This is performed depending on whether or not they match. In step F63, if YES, the process moves to step F631. In step F631, it is determined that the importance of the alarm generation management data D14 is "recovery", and the importance determination processing ends. This confirmation processing is performed by, for example, the alarm generation management data D14.
Can be provided in the register 3 or the processing unit 4, and the flag can be used by the flag. If NO in step F63, the process moves to step F64.

In step F64, it is determined whether or not the degree of importance of the fault indicates the above-mentioned "instantaneous". This decision
Each bit of the alarm generation management data D14 and the determination data "0"
0000111 "and the resulting bit is the significance determination definition data 24 indicating" instantaneous ".
This is performed depending on whether or not they match. If YES in step F64, the process moves to step F641. In step F641, it is determined that the importance of the alarm generation management data D14 is "instantaneous", and the importance determination processing ends. This confirmation processing is performed by, for example, the alarm generation management data D14.
Can be provided in the register 3 or the processing unit 4, and the flag can be used by the flag. In the case of NO at step F64, the process of determining importance is ended. When the importance determination processing shown in FIG. 7 is completed, the process proceeds to step F8 shown in FIG.

In step F8 of FIG.
The ground processing is performed according to the importance of the obstacle determined in step S7. In this case, since the ground data D12 used for the ground processing has already been transferred to the register 3, a new RAM 2
It is not necessary to transfer the data to the register 3. This step F
At 8, the ground processing is performed in accordance with the ground data D12 already transferred to the register. Next, in step F9, an alarm is notified to the higher-level device according to the importance of the failure determined in step F7. In this case, since the notification data D12 used for the notification process has already been transferred to the register 3, there is no need to newly transfer the notification data D12 from the RAM 2 to the register 3.

Next, in step F10, if it is determined that the alarm processing is completed for all the monitored parts in the same package, the process returns to step F2 if NO, and the alarm process is performed if YES. End at the time. The operations from Step F1 to Step F10 are repeated every second.

As described above, in the present embodiment, the number of data transfers from the RAM 2 to the register 3 can be reduced when performing an alarm process. Therefore, RAM2
The number of accesses to the RAM 2 can be reduced, and the increase in the number of accesses to the RAM 2 can be minimized even when the number of monitored units increases.
