The present invention relates to a method for driving a system alarm, and more particularly, to a method for determining a class of a system alarm, driving an alarm according to a corresponding information level, and displaying an alarm content.

In general, the failure of the system can occur anytime, anywhere, so that the system can be used efficiently only when it is possible to detect and notify the failure state most quickly and accurately. However, in the conventional case, a method of assigning a rating to an alarm is fixed to display an alarm state regardless of the importance of the alarm, and it is inefficient in displaying the contents of the generated alarm.

For example, in a switching system, a subscriber who has registered a wake up service may be given a ring when the wakeup time arrives, but the ringer may not receive the ring. In such a case, it is necessary to inform the operator or the system operator of this fact as an important alarm for customer service, but in such a case, the wake-up service is not important in the business exchange. There is no need to inform the operator. Even in the same function, the importance of the function may change according to time and place.

Nevertheless, these functions were fixed in the exchange system irrespective of their importance, and there was a problem that the detailed information on the alarm could not be provided because the alarm was simply displayed.

Accordingly, an object of the present invention is to provide a method for determining the grade of an alarm independently of the task for which the alarm is to be announced.

Another object of the present invention is to provide a method for quickly and accurately displaying information by reducing the amount of alarm messages between a system and a console.

Still another object of the present invention is to provide a method of accumulating information on an alarm and displaying all information generated when necessary through a monitor.

Hereinafter, the present invention will be described in detail with reference to the drawings.

It consists of a time field representing.

Based on the above-described configuration, the present invention will be described in detail with reference to FIGS.

First, the relationship between the system and the alarm device will be described with reference to FIG. 1. The system 110 refers to a device for alerting the alarm to the outside, and the alarm device refers to the sum of devices used to notify the alarm. There is an alarm panel 120, console 130, maintenance terminal 140, and the like. The alarm panel 120 is attached to the system 110 and can be driven directly from the system 110 because it is directly controlled by the address data and the control bus of the system 110. However, since only the alarm indicator (21-2N) is attached to the alarm panel (120), it is not only able to show detailed information on the alarm, but also measures against the alarm because the system operator is not always near the system (110). There may be times when you cannot take.

The console 130 is a terminal used by a system operator. When the console 130 is notified of an alarm, a system operator having expert knowledge of the system 110 may quickly and accurately take action on the alarm. However, since the console 130 is not a terminal used to notify the alarm, there are many obstacles to obtain detailed information about the alarm.

The system 110 may have N kinds of alarms, and the alarm panel 120 and the console 130 have N alarm indicators corresponding thereto. Therefore, when it is desired to display detailed information on the N alarms, the alarm display function can be performed by using the monitor of the maintenance terminal 140.

When the random alarm request signal is generated, the system 110 compares it with the alarm installation table, determines the alarm level, accumulates information on the corresponding alarm, and displays it on the console 130 and the maintenance terminal. The flow of the invention proceeds as follows.

There may be a number of tasks (TASK) in the system 110 that detect the status of the failures, which are TASK1, TASK2,... Assume that TASKN (N is any positive integer). In each of the above tasks TASK1-TASKN, a data value for sounding an alarm is registered in the alarm request table TBL2. The alert request table TBL2 registers information on alerts in the above tasks TASK1-TASKN, and has a unique area designated for each task TASK1-TASKN. That is, the above tasks TASK1, TASK2,... The alarm request table TBL1 indicates TALSn: ALMRQST1, ALMRQST2,... The area "ALMRQSTN" is allocated. Therefore, the alarm request table TBL2 is assigned to the "ALM.RQST1", "ALM.RQST2",... It is represented by a set of "ALM.RQSTN". The structure of the alert request table TBL2 has the configuration as shown in FIG. 7. In the data field DATA FIELD stores a data value for ringing an alert, and the content field CONTENT FIELD stores details of the alert. Therefore, each task TASK1-TASKN registers data concerning alerts in the corresponding ALMRQST1-ALMRQSTN area of the alert request table TBL2 in accordance with the structure as shown in FIG.

At this time, when an alarm request signal is generated, the alarm class determining unit 300 determines an alarm class by referring to an alarm installation table TBL1. The alarm installation table TBL1 registers the determination reference value for each task and each alarm class when the system 110 is installed. The alarm installation table TBL1 is shown in FIG. 8 when there are K types of alarms and N types of TASK. Can be. Therefore, if TAab is the reference value for the alert of any task, a is the type of task, b is the rate of alert (1≤b≤K). In addition, TAa1 must be greater than or equal to TAa2 than TAa2.

An alarm request signal of an arbitrary task is accessed from the alarm request table TBL2, and the alarm request signal grade is determined by comparing with the reference data of the corresponding task alarm class of the alarm installation table TBL1, and then accumulates in the alarm accumulation table TBL3. The operation flow of the alarm class determining unit 300 is shown in FIG. First, in step 301, a variable a representing a task type and a variable b representing a warning level are initialized. After performing step 301, access the task number from the alarm installation table TBL1 and set it as the current task variable a. Then, in step 302, whether the current task variable a is greater than the maximum task number a (a> n Check). Here, when the variable a is larger than the maximum task number, it means that there is no task to determine the alarm level to be determined any more, and the alarm level determination routine ends. However, when the variable a is smaller than the maximum task number in step (302), the alarm class of the task variable a is accessed from the alarm installation table TBL1 and set as the current alarm class variable b, and then in step (303). Check if the class number is greater than the lowest alarm class K, the standard alarm class. In this case, the alarm level variable b is greater than K, but when it is large, the alarm request signal of the task does not need to display an alarm occurrence. Therefore, the process proceeds to step 304 to determine the alarm level of the next task from the alarm installation table TBL1. After accessing the next task number and setting it to the current task variable a (a ← a + 1), the process returns to step 302. At this time, the alarm class is a slight alarm class as the alarm class variable a is larger as shown in the alarm installation table TBL1 of FIG. 8, and when b is larger than the standard alarm class for indicating the occurrence of an alarm in step (303), the corresponding alarm class It can be seen that the occurrence is ignored.

At step 303, when the alarm class variable b is smaller than K indicating the slightest level, in step 305, the data field for the alarm request signal of the task is read from the alarm request table TBL2 in step 306. The alarm class is determined by comparing the data field value of the task with the value in the alarm installation table TBL1.

In this case, the ranks of the most urgent alarms to the lowest alarms are sequentially found. Therefore, when the installation data TAab is larger than the value of the data field in step 306, the alarm level is increased by 1 for the variable represented by step 310, and the next alarm level is selected from the corresponding task number in the alarm installation table TBL1. After setting to (b → b + 1), the process returns to step 303.

At this time, when the value of the data field is greater than the installation data TAab in step 306, it is determined that an alarm will occur at an alarm level indicated by the current variable b. When the grade of the corresponding alarm is determined in the above step, it is determined whether the alarm accumulation table TBL3, which is the table that accumulates the alarm in step 307, is full and discarded if it is full. That is, when the alarm is driven while the alarm accumulation table TBL3 is full, information on the alarm cannot be found in the console 140 or the maintenance terminal 140, and thus the consistency becomes inconsistent.

If the alarm accumulation table D is not full in step 307, in step 308, the alarm level, the task number a, the alarm class b, and the alarm request table TBL3 in the alarm accumulation table TBL3 are requested. Register content field and current time saved in the corresponding ALMRQSTa.

The alarm accumulation table TBL3 is a queue in which alarm information is accumulated. In the ALMRAST structure of the alarm request table TBL2 as shown in FIG. 7, the content field, the task number requesting the alarm, the alarm class, and the time at which the alarm was sounded are recorded. . That is, as shown in FIG. 9, the alarm class b is stored in the ALARM FIELD, the task variable a requesting the alarm is stored in the TASK FIELD, and the alert is stored in the CONTENT FIELD. The detailed information on the alarm registered in the alert request table TBL2 is stored in the requested task, and the time at which the alarm is driven is stored in the time field. After storing the alarm message as described above in step 31 displays the alarm generation through the alarm display of the alarm panel 120 and the console 130.

As described above, the alarm class determining unit 300 sequentially selects each task number from the first task TASK1 to the last task TASKN, and for each of the selected tasks, from the closest alarm class to the slightest alarm class that is the criterion for displaying an alarm. It sequentially checks and stores information on the determined alarm level in order by task number in the alarm accumulation table TBL3. After accumulating the alarm information in the alarm accumulation table TBL3 as described above, when the console 130 and the maintenance terminal 140 request to display information on the alarm, the first and second message handlers 400,500 ) Performs a function of formatting and sending the contents of the alarm accumulation table TBL3 to the console 130 or the maintenance terminal 140.

First, referring to FIG. 4, when the first message processing unit 400 transmits the alarm information of the alarm accumulation table TBL3 to the maintenance terminal 140, the maintenance terminal 140 is performed in step 401. Initializes the variable d used for the number of information to be displayed in the index and the index of the alarm accumulation table TBL3. It is checked whether the alarm accumulation table TBL3 is circulated in step 402 after performing the operation in step 401, because the alarm accumulation table TBL3 is Queue, so it can be rotated. At this time, if the alarm accumulation table TBL3 is cycled, the number of alarm information is accumulated in the queue to the maximum. Therefore, in step 403, the index value of the first generated information among the information accumulated in the queue is found and the variable d is assigned to the variable d. Record it. The index of the first generated information is the write point of the queue.

In this case, if it is not circulated in step 402, the index of the first generated information is the beginning of the queue, and the number accumulated in the queue can be easily obtained by referring to the write point of the queue. Is the number of information accumulated in

Thereafter, it is checked whether there is no accumulated number of alarm information (C = O) in step 405, and if no, the display process of the maintenance terminal 140 ends. However, in step 405, if there is a cumulative alarm, in step 406, the variable d (index) obtained in step 403 or 404 is referred to to obtain a position where information to be formatted in the alarm accumulation table TBL3 is located. This is as follows.

Actual position e = First position of alarm cumulative table + d * 1 information size After step 407, the data is extracted from the actual position e in step 407 and sent to the code recognizable by the maintenance terminal 140, and one information is sent. When the display is finished, the index variable d is adjusted in step 408. If the increased index is larger than the size to store the information in the queue, it is initialized, otherwise it is increased. In addition, since the display of one piece of information is finished in step 409, the variable c representing the number of pieces of information to be displayed is reduced, and then the process returns to step 405.

Secondly, the process of transmitting the alarm message to the console 130 by the second message processor 500 and displaying it on the console 130 will be described. In the alarm field and the task field of the information accumulated in the alarm accumulation table TBL3, the corresponding content is recorded as a code value. However, if the code values are displayed on the LCD 30 as it is, it is difficult to recognize the type of task / alarm based on the code values. Therefore, these code values should be converted into character strings and displayed on the LCD 30. However, since the console 130 exchanges information used for operating the system with the system 110, it is preferable to reduce the amount of information exchanged between the system 110 and the console 130 whenever possible. To this end, a code is set in advance between the system 110 and the console 130, and when the code is sent from the system 110, the console 130 converts the corresponding code value into a string and displays it. The above process is described by dividing the functions in the system 110 and the functions in the console 130.

FIG. 5 is a flowchart showing the functions of the system 110. First, in step 501, a variable g representing the number of information to be exported from the information accumulation table TBL3 to the console 130, and among the information not displayed on the console 130 are shown. Find the index where the oldest information is located and write it to variable h. After performing step 501, in step 502, it is checked whether the variable g is 0. When the variable g is 0, since there is no new alarm information accumulated in the alarm accumulation table TBL3, the control proceeds to step 507. Send a message to turn off the alarm indicator of 130). In other words, unlike the alarm display of the maintenance terminal 140, the console 130 displays only newly generated alarms. Accordingly, the console 130 of the information not displayed on the console 130 in the alarm cumulative table TBL3 is used. The alarm information is counted from the variable h indicating the index and the number of alarm information to be transmitted to the console 130 is set as the variable g. Therefore, the variable g is a variable indicating the number of information not displayed in the previous state. If the variable g is 0, it means that the number of information to be displayed on the console 130 has been transmitted.

If the variable g is not 0 in step 502, it means that there is information to be transmitted. Therefore, the flow proceeds to step 503 to obtain the displacement value i of the alarm accumulation table TBL3 to be transmitted as follows. i = The initial position of the alarm cumulative table is + h * 1 size of information.

Thereafter, in step 504, information about one alarm at a position of i is taken out and transmitted to the console 130. Since the processing of one piece of information is completed by performing the step 504, in step 505, the variable h is increased to indicate the location of the next information. If the increased h value is larger than the size of the alarm accumulation table TBL3, Initialize h, and reduce the variable g representing the number of messages processed in step 506. In this case, the initialization in step 505 means that the alarm accumulation table is rounded.

FIG. 6 is a flow chart showing the functions of the console 130. First, in step 601, a single message sent from the system is reached. Thereafter, if it is not an alarm message in step 602, if the message sent from the system in step 606 is a message about an alarm or a message to turn off an alarm display, the existing console service is performed. In this case, if the message is related to the alarm in step 602, the code value is taken out from the message alarm / task field in step 603 and replaced with a corresponding character string. Displayed on the LCD 30, in step 605, the content of 1 CONTENT / TIME field of the message is displayed on the LCD of the console.

As described above, the alarm can be driven to match the system reality in determining the level of the alarm independently of the task for which the alarm is to be sounded, and the content of the alarm can be quickly and accurately reduced while reducing the amount of messages between the system and the console. It can be sent to the console to reduce the alarm driving time and system load, and the maintenance terminal can display all the information in the alarm, so that not only the latest alarm but also the accumulated value of all status alarms can be displayed. There is an advantage to know the operating state of the system accurately.
