Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for preparing an abnormal part estimating process sequence diagram for estimating a detailed abnormal part based on operation abnormality information of a processing device.

[0002]

2. Description of the Related Art In a system for performing a complicated configuration and processing such as monitoring and control of a power system by a computer, an abnormal operation of each unit such as an input / output unit constituting a processing unit and a computer main body is detected as an abnormal code. By obtaining information that estimates the abnormal part of the processing device from the combination of the above, the investigation of the cause of the abnormality and the maintenance are facilitated.

For the abnormal part estimation information for the abnormal code combination, an abnormal part estimation message corresponding to the abnormal code combination is set at the design stage of the processing device, and a message corresponding to the abnormal code is generated when an abnormality occurs. Are displayed as a sequence diagram.

[0004] In another method, a message may be described by a table instead of a message. Further, the contents of the estimation processing may be constructed using an expression method different from the sequence diagram.

[0005]

Conventionally, in order to express the contents of the process of estimating an abnormal part in a sequence diagram, it is necessary to design and manage each information of the abnormal code of the processing unit, the abnormal part estimation message and the sequence diagram. Is required,
When the number of combinations of abnormal codes becomes enormous, the trouble of designing and managing such information becomes large.

Further, if an attempt is made to express a combination of abnormal codes and a sequence diagram in terms of a superordinate concept of an abnormal part, the content of the expression does not specify a detailed part, and maintenance using estimated information becomes difficult.

An object of the present invention is to provide a method for creating a sequence diagram that facilitates the design and management of abnormal part estimation processing information based on a combination of abnormal codes.

[0008]

According to the present invention, information relating to estimation of an abnormal part such as a part in a sequence diagram is stored in a library or a module, managed as reusable information in a database or the like, and the information is used. By creating a sequence diagram using a graphic editing function by CAD or the like, the efficiency of the sequence diagram creation operation is improved. The abnormal operation information of each part of the processing device is detected as an abnormal code, and the abnormal code of each abnormal code is detected. In creating a sequence diagram for estimating an abnormal portion from a combination, a component library for storing basic component data for expressing the sequence diagram, and a combination of the abnormal code and an abnormal portion for estimating an abnormal portion from the component library. A sequence module library that stores module information of estimated sequences, and a graphic editing device Wherein performs table and edit the component library and sequence module library abnormal code, and wherein the edit and manage the sequence diagram using these data as a layered information by.

[0009]

FIG. 1 is a block diagram of a system for creating an abnormal part estimation processing sequence according to an embodiment of the present invention.

The design information 1 is managed, for example, as a database and includes a parts library 2, a sequence module library 3, and sequence diagram information 4.

The component library 2 stores basic component data for expressing a sequence diagram such as an OR logic symbol. The sequence module library 3 accumulates module information of an estimated sequence related to abnormal part estimation, such as pair information of a combination of a plurality of abnormal codes and an abnormal part estimation result corresponding thereto.

[0012] Sequence diagram information 4 accumulates by processor, device failure code list 4 ₁ actual sequence and diagram information 4 ₂
To accumulate.

The graphic editing apparatus 5 performs data editing of the libraries 2 and 3 and editing of sequence diagram information 4 using, for example, CAD.

In the editing, the component data of the sequence diagram stored in the component library 2 is modularized and hierarchized, and attribute information is added to each module, and the module is edited and managed as a reusable module.

Similarly, the module information stored in the sequence module library 3 edits and manages the module information hierarchized using the component library 2.

[0016] Then, graphic editing apparatus 5, by using the information of these libraries 2,3 edit and manage the sequence diagram 4 ₂ and device failure code list 4 _1.

The conversion system 6 performs data conversion for drawing a sequence diagram information 4 ₂ created CRT screen or the like to obtain a real machine for sequence diagram data. Note that the sequence diagram information 4 can be ported as drawing data to another processing device without performing the conversion process.

In the above configuration, the device error code table 4
₁ is converted into data in the format shown in the table below.

[0019]

[Table 1]

For example, when a search is made under the conditions of "analog input board S4" and "operation set value", "105
An abnormal code of "3" is obtained.

To create a sequence diagram using the libraries 2, 3, etc., each component and module has attribute information, refers to device data as necessary, and creates a sequence diagram by a hierarchical combination of each module. Then, the sequence information of the processing device is created by combining the information with the device information.

FIG. 2 shows an example of componentization and modularization of a sequence diagram in a power system monitoring and control device. Using the information of the entire sequence drawing as a top module, classification of processing contents such as an analog input section and a digital input / output section, information on each page of each processing content, information on modules and components included in each page are hierarchized.

FIG. 3 shows a description example of each module in FIG.
7 are shown in FIG. 7, and an example of a sequence diagram created by these modules is shown in FIG.

[0024]

As described above, according to the present invention, information relating to the estimation of an abnormal part such as a part in a sequence diagram is stored in a library and modularized and managed as reusable information in a database or the like. CAD using
The sequence diagram creation work can be made more efficient by creating a sequence diagram using a graphic editing function such as that described above.

When a sequence diagram is created, the sequence diagram is explicitly made into components and modules, and attribute information is added to the components and managed as components. Design information can be used in a directed manner.
