2. Description of the Related Art Japanese Patent Laid-Open Publication No. Hei 05-29192 discloses a technique for specifying the location of a trouble by analyzing and inferring the cause and location of the trouble when the trouble occurs in the apparatus. That is, in the case of this publication, a history indicating the operation history of the semiconductor exposure apparatus and a history of commands input by the operator of the semiconductor exposure apparatus are sequentially recorded, and judgment rules for trouble analysis are provided as a database. It is disclosed that the cause and the trouble part are automatically analyzed and inferred by the record of.

[0003] To further explain this publication, when the unit CPU returns an error in response to an instruction from the master CPU, the master CPU can detect the occurrence of a trouble and stop the operation of the entire apparatus. Then, control is switched to the trouble analysis program. In this case, it is described that information is traced in reverse from data recorded in an external storage device from the time of occurrence of an error, a trouble is specified, and a detailed analysis is performed by a corresponding analysis routine.

On the other hand, in a network monitoring system,
When an alarm is notified from a transmission device to be monitored (hereinafter, referred to as NE), the contents of the alarm are displayed in real time and notified to the operator. This notification is displayed in a list and is made by changing the color of the corresponding symbol on the hierarchical map surface, but the symbol is used as an alarm.
Instead of one-to-one correspondence, in many cases, a plurality of alarms are assigned to one symbol. Therefore, the details of the alarm can be understood from the list. In this list display, it is possible to specify the faulty part by displaying the contents of the alarm notified from the NE as it is, but in order to more easily specify the faulty part and the affected area, it is necessary to store in the database in advance. By retrieving name information such as registered device names and section names, and displaying them in addition to the respective alarm contents, it is possible for an operator to more quickly recognize a faulty part.

[0005]

However, in this method, when a large number of alarms are generated from the NE, the display is gradually delayed due to the processing time for searching the database, and the operator is notified from the alarm generation. It will take time.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-described conventional problems, and enables alarm notification to be performed without delay for an operator regardless of the amount of alarm data notified from the NE. It is another object of the present invention to provide an alarm display device which enables display of registration information for assisting identification of a failed part, and enables an operator to quickly recognize the contents of a warning and a failed part.

[0007]

In order to achieve the above object, an alarm display device according to the present invention comprises a data receiving section for receiving alarm data from a transmission device, and an alarm data receiving section for receiving the alarm data. A database search processing unit that searches a database from the database and adds information corresponding to the alarm data, and monitors a storage amount of alarm data stored in the data reception unit that has not been processed by the database search processing unit. A processing determining unit for instructing the database search processing unit to perform a search process, and displaying a list of data from the database search processing unit, and again displaying a database to the database search processing unit in accordance with the displayed data. And a data display unit for instructing a search.

According to the present invention, when the data receiving section receives the alarm data transmitted from the transmission device, the database search processing section searches the database from the alarm data received by the data receiving section, and stores the data in the alarm data. The corresponding retrieved information is added to the alarm data and displayed on the data display unit. The processing determination unit monitors the search processing status for the alarm data by the database search processing unit, and when the unprocessed alarm data is stored in the data receiving unit, the alarm data is stored in the data receiving unit for the database search processing unit. Along with instructing the execution of the alarm data search process, the data display unit searches the database for the alarm data that has not been subjected to the database search process from the alarm data displayed in a list of the search results displayed on the data display unit. The processing unit is instructed to perform the database search process again.

[0009]

Next, an embodiment of an alarm display device according to the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing the configuration of the first embodiment. In FIG. 1, alarm data is transmitted from the NE 1 to the data receiving unit 2 of the network monitoring system A. The data receiving section 2 receives the alarm data and sequentially accumulates the data in a buffer (not shown) in the data receiving section 2 in the order of reception. The data receiving unit 1 notifies the database search processing unit 3 that the data is received by the data receiving unit 2 and stored in the buffer.

When the database search processing unit 3 receives this notification, it acquires alarm data from the data receiving unit 1 and adds information corresponding to the contents of the alarm data to the data display unit 4.
To be displayed on the data display unit 4 as a list. Further, the processing determination unit 5 monitors the amount of alarm data stored in the buffer of the data receiving unit 2 that has not been processed by the database search processing unit 3 yet. It is instructed to execute a search process. Further, the data display unit 4 displays the list of data from the database search processing unit 3 as described above, and notifies the operator of the list-displayed data. Then, in response to the instruction, an instruction to perform a database search again from the data display unit 4 is output to the database search processing unit 3.

Next, the operation of the first embodiment configured as described above will be described. When the alarm data is transmitted from the NE 1 to the data receiving unit 2, the data receiving unit 2 receives the alarm data, sequentially stores the alarm data in a buffer held inside the data receiving unit 2 in the order of reception, and stores the data in the database. The search processing unit 3 is notified that the alarm data is stored. When the database search processing unit 3 receives the notification that the alarm data is stored from the data receiving unit 2, the database search processing unit 3 acquires one of the alarm data stored in the buffer of the data receiving unit 2. Then, the alarm data is cleared from the buffer.

The database search processing section 3 searches and obtains a database relating to the corresponding registration information which assists in specifying a faulty part from the contents of the obtained alarm data, and adds the obtained registration information to the alarm data. To the data display unit 4. The data display unit 4 displays the alarm data notified from the database search processing unit 3, and notifies the operator of the occurrence of the alarm and the contents thereof. Further, the processing determination unit 5 monitors the number of unprocessed alarm data that has not been searched by the database search processing unit 3 and stored in a buffer in the data receiving unit 2 and determines a predetermined threshold value in the alarm data. If the number exceeds (that is, the threshold value <the number of alarm data), the processing determination unit 5 instructs the database search processing unit 3 not to execute the search.

Contrary to the above, after the number of alarm data is below the threshold and the database search processing unit 3 stops searching the buffer of the data receiving unit 2 for alarm data, the processing is performed when the number of alarm data exceeds the threshold. The determination unit 5 instructs the database search unit 3 to restart the search. Upon receiving the search restart instruction, the database search processing unit 3 acquires one of the alarm data stored in the buffer of the data reception unit 2 and clears the alarm data from the buffer until the processing of executing the search is completed. Regardless of whether or not the search is possible, the database search processing unit 3 does not execute the search.
Is instructed by the processing determination unit 5, the database search processing unit 3 notifies the data display unit 4 as it is.

Therefore, the data display unit 4 displays the alarm data for which the data search has not been performed by the database search processing unit 3 without any registration information, and displays the alarm data as it is. A search for registration information corresponding to the display data displayed on the section 4 is made by the database display processing section 3 from the data display section 4.
Instruct to. The database search processing unit 3 searches the database for registration information corresponding to the designated alarm data from the data display unit 4, and notifies the data display unit 4 of the search result again. Upon receiving this notification, the data display unit 4 adds the above-described inspection result to the already displayed alarm data to which the registered information is not added, and displays the result.
Thus, the data display unit 4 can notify the operator of the registration information of the alarm data to which the search result is added.

[0015] As a second embodiment of the present invention,
A filter function is added to the data display unit 4 so that alarm data to be displayed is arranged and displayed on a plurality of data display units 4 for each unit, and all alarm data are collectively displayed and displayed in one list. For each type of alarm, for example, it is also possible to display in units such as sections, paths, and devices, and it is also possible to display in units of fault occurrence devices and fault occurrence portions.
