DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for processing event data used in a distributed power system monitoring and control system or the like.

[0002]

2. Description of the Related Art Many of the above-mentioned distributed power system monitoring and control systems edit and print status changes, system statuses, and the like as messages, and store a plurality of lines of the latest messages for display and confirmation as necessary. ing.

Generally, a message editing program is started in response to requests from a plurality of programs, and is configured to edit and save various messages. FIG. 3 is an explanatory diagram illustrating an editing procedure of a message program used as event data processing.
Is a message editing program. The message editing program 31 _first receives a message editing request from the function 1 program 321. In response to this editing request, the message editing program 31 refers to the message format database 33 for the message format (data of the message function) and acquires information necessary for editing (contents to be arranged, etc.).

The message editing program 31 has a function 1
The message is edited with reference to the database 34 ₁ (database of other functions as necessary). The edited data is stored in the save area (message function database) 3
5 is saved. It should be noted that there is a possibility that an editing request may come from a plurality of functions, and these must also be performed in the same manner. For this purpose, in the figure, a function n program 32 _n and a function n database 34 _n are provided for an editing request from the function n. In addition to the above, search processing or the like must be performed in response to a search request (a request for display or the like) from a man-machine or the like.

[0005]

As shown in FIG. 3, in the message program editing procedure, the method of editing and saving a message is realized by a single message program. For this reason, the trouble of having to edit the message by referring to various data according to the message format becomes enormous. In addition, as the functions of the system become more complicated, the types of messages and editing contents also become more complicated,
For this reason, there is a problem that the number of storages increases and the processing load and the like become enormous.

The present invention has been made in view of the above circumstances, and has as its object to provide a method of processing event data which facilitates workability and reduces a processing load.

[0007]

SUMMARY OF THE INVENTION In order to achieve the above object, a first aspect of the present invention is to provide an editing program which, upon receiving a message editing request from a function program, refers to the function database, and After the program edits the message, it sends a registration request to the storage program, then obtains information to be stored by the storage program with reference to the information table, and based on the obtained information, the storage program stores the information in the storage area. It is characterized in that registration is performed.

A second invention is a distributed system in which a plurality of computers are provided on a network, and a plurality of functional programs are installed in these computers, wherein an editing program for editing a message is installed for each of the computers, The message edited by the editing program is distributed to a storage program, an information table and a storage area, and a registration request is transmitted from a computer on which the editing program is installed to a computer on which the storage program is installed via a network. And processing the message.

A third invention is characterized in that an editing program, a storage program, an information table and a storage area are mounted on the same computer.

[0010]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is an explanatory diagram showing the configuration of an embodiment of the present invention. In FIG. 1, an editing program 11 receives a message editing request from a program 12 of function 1. In response to this message editing request, the editing program 11 causes the message format database 1
With reference to the format from No. 3, information such as arrangement necessary for editing and contents to be arranged is acquired. The editing program 11 is started by a computer (not shown) in which data necessary for the message to be edited exists, and edits the message by referring to the editing data in the database 14 of the function 1 in response to the message editing request. Do. After editing this message, the editing program 11 sends a registration request to the storage program 15.

[0011] The storage program 15 receiving the registration request
Refers to an information table (described later) of the information table database 16 and acquires information to be stored. Based on the acquired information, the storage program 15 registers the nth record in the storage area database 17. The information table has one record size, the maximum number of records,
It is composed of information such as a start pointer and an end pointer. For this reason, the storage program can execute processing with reference to the information table in which the size of the message and the like are defined, and the format (contents, format) of the message
The storage process can be performed without being conscious of.

As described above, the following effects can be obtained by causing the message storage program 15 to execute processing with reference to the information table of the information table database 16. (A) Since the contents and format of the message are not considered, any event data can be handled simply by changing the information table regardless of the contents or the like. (B) By inputting unique information into the information table, it becomes possible to execute processing such as message search, and to reduce the load on other functions (such as man-machine).

The data transfer from the editing program 11 to the storage program 15 is performed by data communication. Therefore, the editing program 11 and the storage program 1
5 need not necessarily be in the same computer. Therefore, by sharing and executing the processing, the system can be freely configured according to the operation of the system and the load on each computer. Further, the above-described embodiment can be applied not only to event data but also to other stored data.

As described above, in the embodiment of the present invention, the processing for editing and storing the message is stopped by one program, and the processing for editing the message and the processing for storing the message 15 are performed separately. did. For this reason, the processing load is reduced, and the storage program 15 can be processed by a computer different from the editing program 11, so that the configuration is applied to a distributed system.

FIG. 2 is an explanatory diagram of a configuration applied to the distributed system. FIG. 2 shows a configuration in which a plurality of computers A, B, and C are provided on a network. In Figure 2, the computer A, the editing program 11, a message format database 13, a database 14 ₁ program 12 ₁ and function 1 function 1 is mounted, to a computer B, the editing program 11, a message format database 13, features 2 programs 12 ₂
Is a function database 14 ₂ implementation of 2, the computer C, the editing program 11, functions 3 Program 1
2 ₃ , function 3 database 14 ₃ , storage program 1
5. An information table database 16 and a storage area database 17 are respectively mounted.

The editing program 11 of each of the computers A, B, and C requests the saving program 15 to save via the network, and is saved in the saving area database 17. When a message is used for display / printing, the program acquires the message from the storage program 15. This is because the storage area database 17 is managed by the storage program 15.

When used in a centralized system,
Only one editing program and storage program are activated (a plurality of editing programs may be activated depending on the situation), and the computer C has all functions.

As shown in FIG. 2, each computer A, B,
By configuring C as a distributed system, message editing is performed by, for example, the computer A, and message storage is performed using the storage program 15, the information table database 16, and the storage area database 17 of the computer C via a network. Do. in this way,
If editing and saving are performed using a computer on which the target function is implemented, it is effective even in consideration of processing efficiency, system load, and the like. In addition, as described above, the saving program 15 Although the case where the processing is performed by a computer different from the editing program 11 has been described, the editing and storage program, the information table, the storage area, and the like may be provided in the same computer.

[0019]

As described above, according to the present invention,
By executing the message editing and saving with separate programs, the message editing program executes processing on a computer having necessary data, so that the processing load and the like can be reduced. Further, since the message storage program can execute processing on a computer different from the message editing program, a flexible configuration suitable for a distributed system can be obtained.
