Abstract

PURPOSE:To easily perform the maintenance of a program component by unifying processings spreading over plural states or events in one program component in case of generating a state transition table including a large number of similar processings. CONSTITUTION:The processing spreading over the plural states or events in the state transition table 3 are held as one component, and it is held in a specification data base 1, and specifications are changed at the time of performing the development of a new system. Therefore, it is possible to select the program component corresponding to each state or event, to deform the processing to the one suitable for an event name, and to obtain the state transition table 3 suitable for the specification. In such a way, the number of program components can be reduced, and the maintenance can be performed easily,. and also, it is possible to generate the program of the processing generated individually manually in an on-going system automatically from the program component, therefore, the state transition table with high reliability can be generated in a short term.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a state transition table for controlling a device by transitioning the state within the device based on an event that occurs, for example in the field of device control. The present invention relates to a device that automatically generates.

Conventional technology Generally, as a method for controlling equipment, a state transition table is used that describes the state of the equipment, the events that cause the state to transition, and the processing that is executed when an event occurs during a specific state. is often used.

However, state transition tables generally determine state names and event names based on the smallest processing unit.

Same processing for multiple status names and event names.

Processes with similar functions often exist.

Conventionally, when developing a new system using such a state transition table, all processes corresponding to individual events and states were created individually.

I was creating the desired state transition table.

Problem to be Solved by the Invention When developing a new device, manually creating individual modules of state transition tables that contain many similar processes is a monotonous task, but it takes a lot of time to develop. This has the problem of requiring a lot of time and also leading to the occurrence of human error.

The present invention aims to solve the above problems by consolidating processes with similar functions into one program component and creating a new state transition table with few errors in a short time by changing the specifications. This is an automatic state transition table generation device.

Means to Solve the Problem This is a system that reuses accumulated software resources and automatically generates a state transition table that matches the specifications of a new device. A specification database that holds attribute items that express state names, event names, and functions; a main body that expresses processing that realizes a state transition table determined by the state name and event name; A program parts database that contains part rules that describe rules for deleting part of a process, and that holds program parts that can be applied to multiple state names and event names; Determine a specific device compatible status name indicating a status name and a specific device compatible event name indicating an event name, and select a program component corresponding to the specific device compatible status name and the specific device compatible event name from the program component database. , and a state transition table synthesis unit that creates a state transition table of the device to be synthesized with the state transition table by transforming the state transition table to match the content of the drafting item in the specification database.

Operation Since the present invention is a device that intentionally generates a state transition table with the above-described configuration, if the state transition table automatic generation device of the present invention is used, processing that spans multiple states and events in the state transition table can be performed. By keeping it as one component, storing it in a specification database, and changing the specifications when developing a new system, you can select the program component corresponding to each state and event, and transform it into a process that matches the state name and event name. ,
A state transition table that meets the specifications can be obtained.

This reduces the number of program parts, making maintenance easier. At the same time, programs that previously had to be created individually by hand can now be automatically created from program parts. It becomes possible to create a high-quality state transition table.

Embodiment An embodiment of the state transition table automatic generation device of the present invention will be described below with reference to FIGS. 1 to 4.

FIG. 1 is a block diagram showing the configuration of a state transition table automatic generation device which is an embodiment of the present invention, and includes a specification database 1 that holds specifications, a program parts database 2 that holds reusable program parts. , a state transition table synthesis unit 4 that generates a state transition table 3 from the contents of the specification database 1 and the program component database 2.

FIG. 3 shows an example of program parts held in the program parts database. A program part consists of a part rule and a main body, and the part rule contains the event name for which the program part was selected.

By referring to the status name and specification database, the block number of the main body (1, 2° of the main body in Figure 3...
) is described.

In the main body of FIG. 3, block numbers to be deleted according to component rules and corresponding processing are described.

The state transition table synthesis unit 4 determines the states and events of the state transition table shown in FIG. 4 by referring to the specification database 1.

In FIG. 4, Pij indicates processing corresponding to event Σi and state Sj.

The state transition table synthesis unit 4 selects the optimal program parts for determining each process P4j from the program parts database 2.
After making a selection, the main body is transformed according to the part rules while referring to the specification database 1.

By repeating this series of operations, the process P+ in FIG.
1. P, 21, . . . are sequentially generated to obtain a state transition table 3 that meets the specifications.

Effects of the Invention By using the state transition table automatic generation device of the present invention described above, when creating a state transition table that includes many similar processes, processes that span multiple states and events can be combined into one program component. As a result, the number of program parts can be reduced, making maintenance of the program parts easier.

In addition, when creating a state transition table when developing a new system, the desired state transition table can be obtained by simply changing the specifications, so individual processes can be created manually in an extremely short period of time compared to conventional methods. It is possible to create a state transition table that is more reliable than the previous method.
