Description

  The present invention relates to an automatic program generation device, an automatic program generation method, and an automatic program generation program, and more particularly, to an automatic program generation device having a switching process, an automatic program generation method, and an automatic program generation program.

  Digital control using a computer has already been put into practical use in large-scale plants such as rolling plants and power plants and industrial machinery. In such a large-scale plant, industrial machine, and the like, a control program is required to perform digital control.

  Therefore, high-level languages such as C language are widely used for developing this program. A program created in a high-level language is converted into a load module using a compiler or the like and processed by a computer.

In general, a document is created simultaneously with a high-level language program. This document is often created using a lot of graphics to improve visual comprehension.
However, it has been regarded as a problem that many human errors occur when a program is manually created on the basis of a document created by this figure.

  Therefore, at present, automatic generation from a graphic-based document to a text-based program has been realized (see, for example, Patent Documents 1, 2, 3, and 4). This automatic program generation reduces the human error of the developer and shortens the operation time. In addition, the developer does not need to describe and generate two graphics-based documents and text-based programs separately, which further improves the program development efficiency.

  Note that a figure-based document may take a form called a data flow diagram in which a plurality of blocks are connected, as disclosed in, for example, Patent Document 2. The outline of this data flow diagram will be described below.

FIG. 14 is a diagram showing an example of a conventional data flow diagram.
The data flow diagram describes the flow of processing executed by each function. The data flow diagram 500 shown in FIG. 14 includes a start block 510, 511, a normal block 520, 521, 522, 523, 524, a termination block 550, 551, a branch point 530, a holding block 540, 541, and a logic block 560. is described. The data input / output relationship between these functional blocks is described by arrow lines as shown in FIG.

  The start block means an input value given from outside the function at the start of processing. In many cases, one or more starting blocks are described per data flow diagram. In the data flow diagram 500 shown in FIG. 14, two input values (input values corresponding to the start block 510 and the start block 511) are given at the start of processing.

  A normal block means a certain set of data processing. In each normal block, the data output along the arrow line is calculated based on the data input along the arrow line. For example, in the normal block 520 in FIG. 14, data to be output to the normal block 521 is calculated based on the input value given in the start block 510.

  The end block means a return value output to the outside of the function at the end of processing. In many cases, one or more termination blocks are described per data flow diagram. In the data flow diagram 500 shown in FIG. 14, data output from the holding block 540 or the logic block 560 described later is output as final return values (return values corresponding to the termination block 550 and the termination block 551). .

  The holding block means data processing for holding input data or calculating and outputting the data to the next block while holding the data. In the case of a normal block, once data is input, the data is once held in a work area or the like. Thereafter, when data is output, the role of the work area ends and is discarded. However, for example, the holding block 540 of FIG. 14 performs calculation while holding the data output from the normal block 522, and outputs the calculation result. By holding the data, it is possible to prepare for the case where the data needs to be held, such as referring to the data from outside the holding block.

The logical block means data processing for outputting either true (FALSE) or false (FALSE) for input data.
The above data flow diagram 500 can be created based on user operation input. By using such a data flow diagram 500, the user can easily understand the flow of processing executed inside the function.

FIG. 15 is a diagram showing another example of a conventional data flow diagram.
As another example of a data flow diagram, the data flow diagram 600 of FIG. 15 is similar to the data flow diagram 500 by a start block 610, 650, 651, an end block 652, a normal block 620, 621, 622, and a logic block 660. is described. Further, in FIG. 15, a switching block 690 is connected as a switching element. Further, the data input / output relationship between these functional blocks is described by arrow lines as shown in FIG.

  The switching block means data processing for switching output according to input data. For example, in FIG. 15, when the signal from the function corresponding to the logical block 660 is true, it is regarded as an output from the normal block 620 to the normal block 622 via the switching block 690. On the other hand, when the signal from the function corresponding to the logical block 660 is false, it is regarded as an output from the normal block 621 to the normal block 622 via the switching block 690.

As shown in FIGS. 14 and 15, the data flow diagram using blocks can describe various notations, and is suitable for describing processes that proceed by data transfer.

However, automatic generation from a figure-based document to a text-based program has the following problems.
The content described in the data flow diagram requires processing time because it involves processing. For example, the input value of start block 610 of FIG. 15 is input to logic block 660 to determine whether it is true or false. If true, the data is output from the normal block 620 to the normal block 622 side. However, on the other hand, calculation of data processing on the normal block 621 side is performed. As a result, the calculation of data processing from the normal block 621 side is discarded. Thus, since the switching block 690 performs processing, there is a problem that unnecessary processing is performed and extra time is required.

  Further, in such a case, there is a case where execution control is performed by inputting data on whether to call the block to the block. However, in such a control method, the contents of the process are hidden, so that there is a problem in that automatic generation of the program is not appropriately performed.

[Step S11] The source code generation unit 150 secures a source file storage area corresponding to the selected functional block.
[Step S12] The source code generation unit 150 selects one unselected functional block from the data flow diagram received from the data flow diagram storage unit 120 in order from the start block.

  [Step S13] The source code generation unit 150 determines whether the block selected in Step S12 is a normal block. If it is a normal block, the process proceeds to step S14; otherwise, the process proceeds to step S15.

Append to the source file storage area.

  [Step S17] The source code generation unit 150 determines whether the block selected in Step S12 is a logical block. If it is a logical block, the process proceeds to step S18; otherwise, the process proceeds to step S29.

Next, when there is a block, the process proceeds to step S21, and when there is no block, the process proceeds to step S23. If there is no next block, the process in the switching block area is completed, and the process continues for the block that is outside the switching block area.

  [Step S28] The source code generation unit 150 selects a function corresponding to the logical block selected in Step S27 from the functional block library storage unit 110, creates a function call statement corresponding to the logical block, and secures it in Step S11.

A data flow diagram to be programmed by the automatic program generation device 100 will be described below with reference to a data flow diagram as a specific example.

In the first example, a case will be described in which the entire block row is surrounded by the switching block area.
FIG. 5 is a diagram illustrating a data flow diagram of the first example.

The case where the data flow diagram 121 shown in FIG. 5 is created by the automatic program generation device 100 will be described as an example.
The data flow diagram 121 includes a start block 121a, a logical block 121b, normal blocks 121d, 121e, and 121f, an end block 121g, and a switching block area 121aa surrounding them.

  In the data flow diagram 121, an input value corresponding to the start block 121a is input to the logical block 121b. The function corresponding to the logic block 121b returns a true or false value depending on the input value. When true, the functions corresponding to the normal blocks 121d, 121e, and 121f in the switching block area 121aa sequentially process, and output an output value corresponding to the terminal block 121g.

FIG. 6 is a diagram illustrating an example of an implementation code generated from the data flow diagram of the first example.
FIG. 6 shows an example of the mounting code generated by the automatic program generation device 100 from the data flow diagram 121 of FIG.

The implementation code 131 is described with a grammar similar to the C language for explanation. Then, it is stored in the source file storage unit 130.
The argument of the function declaration statement 131a corresponds to the start block 121a of the data flow diagram 121 of FIG. 5 and the function call statement 131b corresponds to the logical block 121b of the data flow diagram 121 of FIG. in_1 "is given to the function to obtain the output data" out_f ".

  The if statement 131c corresponds to the switching block 121aa in the data flow diagram 121 in FIG. When the output data “out_f” is true, this corresponds to the processing sequentially performed in the normal blocks 121d, 121e, and 121f in the switching block area 121aa in the data flow diagram 121 in FIG.
