Abstract

PURPOSE:To simplify a table form and to shorten an on-line execution time by dividing an input diagnostic logic diagram into a logical operation part and a table of model data base, etc., when converting the input diagnostic logic diagram into an object. CONSTITUTION:An operator edits and inputs the diagnostic logic diagram 5 on an interactive input device 5 by using a diagram editor 6 to generate diagram data, which is stored in a storage device 7. Then, a diagram language processor 8 is used to translate the data stored in the storage device 7 into an execution object program, which is stored in a storage device 9. Consequently, the execution object program is merged by a diagnostic execution processor 4 and used for diagnostic processing. In this case, the object program generated by the processor 8 is divided into the logical arithmetic execution module and table of model date base, etc., so it is expressed simply and executed speedily.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to an abnormality diagnosis device that detects failures and abnormalities in a control system such as a plant system based on a diagnostic program and notifies an operator.

[Prior art]

Conventionally, there has been a device of this type as shown in FIG.

In the figure, 1 is a diagnostic program, 2 is an abnormality diagnostic device, and 3 and 4 are execution program conversion processors 5 and diagnostic execution processors of the abnormality diagnostic device (large).

In this device, first, on the premise that the contents of the abnormality diagnosis processing are all completed in the form of computer processing programs, this diagnostic program 1 is transferred to the abnormality diagnosis device 2.
is input to the executable program conversion processor 3, and iJN of compile link is performed. Next, this converted object program is transferred to the diagnostic processor, and the diagnostic processing specified for this program is executed.

As a result, if there is an abnormality in the system, the operator will be informed of the problem.

In this case, the source diagnostic program can either be a general tree-like data structure and run through an ink printer at runtime, or it can be written as a special program that relies entirely on diagnostic logic. It is being

However, with conventional abnormality diagnostic devices, all the detailed contents of the computer's diagnostic processing must be created by program coding, which is extremely complicated and prone to procedural errors.
It also had drawbacks such as difficulty in maintenance such as modification and lack of reliability. Furthermore, if the execution program is an ink printer of a tree format database, the execution time will be long, and if it is a special program, the execution program size will be large, making programming extremely complicated.

[Summary of the invention]

This invention was made in order to eliminate the above-mentioned conventional drawbacks, and it makes it possible to interactively input a cause-and-effect tree of diagnostic logic and execute diagnostic analysis based on the logic diagram. In addition, by dividing the object program format into a data base (model database) that indicates logical operations and connection relationships, and using the logical operation results (prediction status) in diagnostic analysis, connection relationships can be determined directly using only the node numbers of the second node. The object of the present invention is to provide an abnormality diagnosis device that can be made into a simple format.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to FIG.

In FIG. 2, reference numeral 5 denotes an interactive human-powered device having a CRT display device, keyboard, tablet, etc. for performing interactive operations, and 6 creates diagram data for managing the diagnostic logic diagram inputted by the interactive human-powered device 5. OCT diagram editor, 7 is a storage device for storing the diagram data created with the Gweet Durham editor 6, 8 is a storage device that analyzes the diagram data created with the diagram editor 6, and creates an object module of diagnostic logic and various tables necessary for it. 9 is a storage device that stores the diagnostic logic object module created by the language processor and various tables, and 10 is a storage device that stores the diagnostic analysis program. 34 is a diagnostic execution processor that combines data stored in the storage devices 9 and 10 and executes diagnostic analysis.

Next, the operation will be explained. First, the operator uses the diagram editor 6 to edit and input the diagnostic logic diagram from the human interaction device 5 to generate diagram data.
It is stored in the storage device 7.

Next, using the diagram language processor 8, the storage device 7
The diagram data stored in the computer is translated into an execution object program, and this is stored in the storage device 9. Then, the execution object 1 to the program are combined and edited by the diagnostic execution processor 4 and used for diagnostic processing. In this case, when it is desired to change the diagnostic logic diagram, the diagram data is changed by interacting with the interactive human-powered device 5 using the diagram editor 6, and then the diagnostic processing is performed using the processor 8 and the diagnostic execution processor 4 in the same manner as above. will be held. By the way, 4 word processor 8
Since the object program generated in is divided into a logic/III calculation execution module, a model database, and other tables, the diagnostic analysis program stored in the storage device 10 can be simplified by using the logic operation results (prediction status). It can be expressed and executed quickly. In particular, for connection relationships, it is sufficient to simply store the node number of the node directly above the model database. As a result, the language processor 8 also has a simple object format, which has the advantage of being able to perform high-speed processing.

In the above embodiments, cause-and-effect free methods have been described, but methods involving general tree-type logical operations can also be applied. Further, although a CRT, a keyboard, and a multi-bullet are used as the dialogue person output devices, an OCR (optical graphic reader) or its extraction output device may also be used in combination.

〔Effect of the invention〕

As described above, according to the present invention, when converting a diagnostic logic diagram input interactively into an object, it is divided into a logic operation part, a model data base, and other chienables, so that the table format can be easily converted. This has the effect of reducing online execution time and simplifying the language process.
