Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system construction apparatus and a system construction method, and more particularly, to a single tool,
The present invention relates to a system construction apparatus and a system construction method improved to enable high-speed and flexible processing.

[0002]

2. Description of the Related Art Conventionally, CAD (Computer Aided Desig)
n) Systems designed using tools are roughly classified into the following two types of implementations. That is, the first mode of realization is generally called a fixed program, and converts a design result into a program described in a predetermined program language (for example, C ++ language). This implementation is
In general, high-speed processing is possible depending on the language used. However, when it is desired to change the settings of the system, there is a disadvantage that the entire system must be corrected again by the CAD tool and converted again.

On the other hand, the second mode of realization is generally called a variable program, and outputs a design result as a data file for an execution program separately prepared in advance. In this embodiment, the execution program reads and analyzes the data file to reproduce the design result therein. In this case, the setting can be changed without re-conversion by replacing the data file.However, since the execution program needs to be created for general use, the program size becomes large, and the execution speed becomes slow. There was a disadvantage of becoming.

[0004]

Conventionally, a system construction apparatus such as a CAD tool or the like usually provides only one of a fixed program and a variable program. You had to choose a tool depending on whether you wanted to be fast or flexible.

[0005] On the other hand, in order to enable the above two implementations for the same system, it is necessary to prepare two types of tools capable of creating each of a fixed program and a variable program. did not become. Moreover, in this case, data compatibility between different tools is often not guaranteed, so that a design work is required for each tool.

A CAD for creating a variable program
As a tool, there were the following problems. That is, in the variable-type program, as described above, the execution program reads the design result as a data file, but the format of the data file read by this program differs from the format of the file used by the CAD tool itself when designing the program. Was. Therefore, the data file read by the execution program cannot be created or modified using a CAD tool for program design, and a dedicated tool is required.

For example, a fuzzy inference system or the like
In the case of using the D tool, a rule is used in which rules are made variable, and a rule part is created using a dedicated tool later. However, in this case, as a file structure when a system is created or saved by the CAD tool, a format suitable for the CAD tool is used. On the other hand, after the system is completed, a file structure of a variable portion created by a dedicated tool is used. As such, a format appropriate for the dedicated tool was used.

[0008] The reason is that many operations are required to construct a system using a CAD tool, and a file structure suitable for such many processes is used. It is because high-speed and operability are required to correct and supplement a part of, and a format specialized for each program is easier to use.

As described above, two types of tools must be prepared in order to enable the above-described two forms of implementation in a conventional system construction apparatus, and the file structure of each tool is different. However, the files could not be shared with each other, and the versatility as a CAD tool was poor.

The present invention has been proposed to solve the above-mentioned problems of the prior art, and has as its object to provide a system construction apparatus capable of performing high-speed and flexible processing with a single tool. It is an object of the present invention to provide a medium on which a system construction method and a system construction program are recorded.

[0011]

In order to achieve the above object, a system construction apparatus according to a first aspect of the present invention provides a fixed type program conversion means for converting a design result of a design target system into a predetermined processing program, A variable program generating means for generating a variable program having a variable section for changing a setting of the system to be designed, so that the fixed program converting means or the variable program generating means can be selectively activated. It is characterized by having done. The invention described in claim 5 captures the invention described in claim 1 from the viewpoint of a method,
A fixed program conversion step of converting a design result of the design target system into a predetermined processing program; and a variable program generation step of generating a variable program having a variable unit for changing the setting of the design target system. The fixed program conversion step or the variable program generation step can be selectively activated.

According to the system construction apparatus according to the first aspect and the system construction method according to the fifth aspect having the above configuration, after the program is installed in the target environment,
If the setting is unlikely to be changed, it is possible to output a fixed-type program in which all the system design results are converted into source codes according to a user's instruction. On the other hand, when there is a high possibility that the setting is changed after the mounting, a variable unit capable of changing the setting after the mounting is generated according to a user's instruction, and a variable program incorporating the variable unit can be output. This makes it possible to selectively output both fixed programs and variable programs with a single tool. In addition, since the user can freely specify the setting variable portion of the system to be designed, a conversion program having an appropriate configuration according to the possibility of changing the system after mounting can be obtained.

According to a second aspect of the present invention, in the system construction apparatus according to the first aspect, storage means for recording all or a part of the design result of the design target system as design information based on a predetermined format, A reproduction means for reading and reproducing the design information is provided. According to a sixth aspect of the present invention, the invention of the second aspect is grasped from the viewpoint of a method. In the system construction method of the fifth aspect, all or all of the design results of the design target system are obtained. The method is characterized by including a storage step of recording part of the design information based on a predetermined format, and a reproduction step of reading and reproducing the design information. According to the system construction apparatus according to the second aspect and the system construction method according to the sixth aspect having the above-described configuration, all or a part of the design result of the design target system is converted into design information in a predetermined format. Since the design information can be recorded on the recording medium and the design information can be read and reproduced as appropriate, the information recorded on the recording medium by another tool can be used when constructing the system.

According to a third aspect of the present invention, in the system construction apparatus according to the second aspect, the variable section has a function of reading the recorded design information. According to a seventh aspect of the present invention, the invention of the third aspect is grasped from the viewpoint of a method, and in the system construction method of the sixth aspect, the variable section stores the recorded information. It has a function of reading design information.

According to the system construction apparatus according to the third aspect and the system construction method according to the seventh aspect, the variable part of the variable type program includes all or all of the design results of the system to be designed. It is possible to read out predetermined design information from a recording medium in which a part is recorded as design information according to a user's instruction, and reproduce the design information on a variable program. Thus, even when the setting is changed after mounting, the data processed by the program can be changed only by rewriting the file without changing the program itself.

According to a fourth aspect of the present invention, in the system construction apparatus of the third aspect, the format of the design information read by the reproducing means and the format of the design information read by the variable section of the variable program are different. It is the same. According to an eighth aspect of the present invention, the invention of the fourth aspect is grasped from the viewpoint of a method. In the system construction method of the seventh aspect, the design information read in the reproducing step is read. The format and the format of the design information read by the variable section of the variable program are the same.

According to the system construction apparatus according to the fourth aspect and the system construction method according to the eighth aspect, the format of the design information read at the time of constructing the system and the change of the variable program Since the format of the design information read by the department is the same, the file created when the completed program was modified / supplemented is read out at the time of system construction and combined with other design results to modify / The design results incorporating the complemented content can be converted back into a program. In addition, since the same system construction device can also supplement the variable part of the variable program, both the construction of the program and the correction / supplement can be performed by one device.

Next, when the user designs a desired system via the user interface unit 2, the data processing unit 3 analyzes information input by the user and performs processing such as processing of the input design information. And stores the processing result in the data storage unit 4 as system design data (SDD). Further, the data processing unit 3 reads out the system design data stored in the data storage unit 4 and, in response to a request from the user interface unit 2, reads each unit (the user interface unit 2, the storage unit 5, reproducing means 6, fixed type program converting means 7, and variable type program generating means 8).

The storage unit 5 outputs the system design data read from the data storage unit 4 to a design result file 9 in a predetermined format. On the other hand, the reproducing means 6 reads out the system design data recorded in the design result file 9 in a predetermined format and reproduces it in the data storage unit 4.

The fixed program conversion means 7 converts the system design data read from the data storage 4 into

Output as 10. On the other hand, when the variable program generation mode is specified, only the portion designated by the user to be a variable program is replaced with a description indicating that the setting is variable, and the other portions are sourced in a predetermined programming language. The program is converted into a code, and the
Output to

Next, the variable program generating means 8 generates a source code having an instruction to read and analyze a predetermined file for a portion designated by the user to be a variable program, as a file reading section, It is combined with the output of the type program conversion means 7 and output as a variable type program 11 outside the system construction apparatus 1.

[1-2. Operation] The system construction apparatus of the present embodiment having the above-described configuration operates as described below. Here, the system S to be created by the user is composed of four subsystems S1, S21, S22 and S23 as shown in FIG. 2 (A), of which S21, S22 and S23 are And represents a single function. Note that there is no clear distinction between the above “system” and “subsystem”, both of which receive input from the outside, execute predetermined processing from this input and the internal setting conditions, Outputs the processing result.

[1-2-1. System Configuration and Design] As described above, in the system S shown in FIG. 2A, the portion including the subsystems S21, S22, and S23 represents one integrated function as a whole. , A new subsystem S2. That is, as shown in FIG. 2B, the system S includes subsystems S1 and S2, and the subsystem S2 has a hierarchical structure and stores subsystems S21, S22, and S23. Can also. In this case, the subsystems S1 and S1
The second hierarchy is “level 1”, and the subsystems S21 and S2
2 and S23 are referred to as “level 2”.

In the system construction apparatus 1 of the present embodiment, the system S is shown in FIG. 2 (A) or FIG. 2 (B).
Can be designed in any form. Also, GU
In the system construction apparatus 1 having I (graphical user interface), an independent window can be provided for each hierarchy of the system to be designed. Here, FIG.
The system is designed in the format shown in FIG.

[1-2-2. Saving of Design Result] When a system is constructed using the present apparatus, the design data created during the system construction is saved in the design result file 9 in a predetermined format by the storage means 5. At this time, the following information is described in each design result file 9. (1) Subsystem connection definition: Connection relationship between subsystems defined in the same hierarchy (signal flow) (2) Internal definition of each subsystem: Internal setting for each subsystem defined in the same hierarchy Information There are the following three types of descriptions of the internal settings used for this (2) subsystem internal definition. (A) Recursive description... When a subsystem is made up of a group of other subsystems, such as the subsystem S2 in FIG. 2A, the subsystem connection definition and each Subsystem internal definitions can be adopted. (B) Detailed description of function: type of processing function uniquely given to the subsystem and setting conditions necessary for executing the processing function are described. (C) Hierarchical information description: subsystem S2 in FIG. 2 (B)
When the file itself has a hierarchical structure and its detailed definition is made in another file, the location of that file is described.

When the system S is designed as shown in FIG. 2B, the design result files 9 are generated by the number of layers of the system S as shown in FIG. 2C. That is, the design results of the system S are stored in two design result files de.
Stored in ffile1 and deffile2. Note that level 1 corresponds to deffile1, and level 2 corresponds to deffile2.

Here, the design results of the system S stored in the two design result files (deffile1, deffile2) shown in FIG. 2C will be described. That is, deffile1
(Level 1) describes a subsystem connection definition indicating a signal flow of input → S1 → S2 → output and internal settings of the subsystems S1 and S2. In this case, the hierarchy information description is made as a subsystem S2 definition,
The location of a design result file deffile2 in which detailed design information of the subsystem S2 is described is shown. On the other hand, de
In ffile2 (level 2), input → (S21, S22, S
23) → Subsystem connection definition indicating the signal flow of “output” and the internal settings of each of the subsystems S21, S22 and S23 are described.

[1-2-3. Reproduction of Design Result] When the system construction apparatus 1 receives an instruction from a user to read the design information of the system S when resuming the construction of the system or generating a program from the completed system, the reproduction means 6 Through the design result file
By reading and analyzing deffile1 and deffile2, the design results can be reproduced in the data storage unit 4 in the system construction apparatus 1.

[1-2-4. Conversion of Design Result into Source Code] System S Designed on System Construction Apparatus 1
In order to implement this function in a target environment, it is necessary to convert system design data into a processing program. In this case, the system construction device 1 of the present embodiment has two modes for converting a design result into a source code. That is, the first mode is a fixed program generation mode, and the second mode is a variable program generation mode. These two modes are configured so that the user can specify them via the user interface unit 2. Here, the result of conversion into the processing program indicates a source code in a predetermined program language (for example, C ++ language), but the same applies to other formats, for example, executable binary code.

[A. Generation of Fixed Program] If the design result of the system S is reliable and the possibility of making a setting change after mounting is low, the user can use the system construction device 1
Select the fixed-type program generation mode via the user interface unit 2. In response, the data processing unit 3 designates the entire system S and activates the fixed program conversion means 7, converts all the design results of the system S into source code, and obtains the fixed program 10. Also,
By giving the conversion result to a separately prepared compiler or the like, the user re-converts the conversion result into an executable format and implements it in a target environment. FIG. 3 shows an image after conversion by the fixed-type program conversion means 7.

[B. Generation of Variable Program] On the other hand, when there is a high possibility that the setting is changed after the system S is mounted, the user selects the variable program generation mode and converts the design result into source code. That is, the user selects a variable program generation mode after designating a set of subsystems to be made variable after mounting via the user interface unit 2.

For example, assume that it is desired to make the subsystem S2 variable. In this case, the data processing unit 3
The fixed program conversion means 7 is started by designating that the variable 2 is variable. The fixed-type program conversion means 7 outputs the source code of the fixed-type program to the variable-type program generation means 8 by replacing only the subsystem S2 with a description indicating that the setting is variable. On the other hand, the data processing unit 3 activates the variable program generation means 8 by specifying the subsystem S2. The variable program generation means 8 is provided with a design result file deffil of the subsystem S2.
A source code having a function of reading and analyzing e2 is generated as a file reading unit, combined with the output of the fixed type program conversion means 7, and the variable type program 11 is output.

In the present embodiment, the file reading section of the variable program 11 is configured by incorporating the source program of the reproducing means 6 of the system construction apparatus 1 at a predetermined position of the variable program. In addition, when the setting variable portion is specified, a part of the design target system can be specified, and when the design target system has a hierarchical structure, it can be specified for each hierarchy. FIG. 4 shows an image of the variable program 11 output by the variable program generating means 8.

[1-3. Effect] According to the system construction apparatus 1 of the present embodiment, both a fixed program and a variable program can be selectively output with a single tool. In addition, since the user can freely specify the setting variable portion of the system to be designed, a conversion program having an appropriate configuration according to the possibility of changing the system after mounting can be obtained. Further, since the setting variable portion is only instructed to read a file, the data processed by the program can be changed only by rewriting the file without changing the program itself.

Since the file reading unit incorporated in the variable program has the same function as the reproducing means 6 provided in the system construction apparatus 1, the subsystem S2 is defined in the design result file 9 of the system construction apparatus 1. Is de
ffile2 can be used as it is. As a result, even after the variable program is implemented in the target environment, unless the definition in deffile1 (that is, the definition of level 1) is changed, the subsystem S2 in the system construction apparatus 1 (that is, level 2)
The design change can be made freely, and the design change can be made without re-conversion by reading the changed file.

[2. Other Embodiments] The present invention is not limited to the above-described embodiments, and the following aspects can be considered. That is, in the above embodiment, the design result file 9 handled by the system construction apparatus 1 is used as it is as the definition file read by the variable program 11, but the present invention is not limited to this. A format definition file may be employed. However, in this case, it is necessary that the reproducing means 6 in the system construction apparatus 1 and the file reading unit in the variable program 11 be functionally equivalent but have different processing. As a result, it is possible to prevent the specification of the variable setting part of the system from depending on the hierarchical structure of the system designed by the system construction apparatus 1.

In the above embodiment, the variable program generating means 8 incorporates the source program of the reproducing means 6 into the variable program 11, but the reproducing means 6 is realized as a library, and 1
The link may be configured to be linked from both the and the variable program 11. In this case, the source program of the reproducing means 6 becomes unnecessary.

Further, it is also possible to make a plurality of portions of the program variable, and thereafter, when a portion that can be fixed is created, only the portion is fixed. In this case, since the file for changing the program and the file for the CAD tool have the same format, the file created when the completed program has been corrected or supplemented is read from the CAD tool side, and is read by the CAD tool. By combining it with the contents of another design result storage file that has been used, the design results obtained by incorporating the contents modified / supplemented by the program can be converted again from the CAD tool into the program.

The variable program generation means 8 may be configured to generate both a fixed part and a variable part of a program. In this case, the synthesizing process with the output from the fixed-type program conversion means 7 becomes unnecessary.

The processing according to the system construction method of the present invention is realized by a computer program controlling a computer, and this program is provided by being recorded on a recording medium.

[0043]

As described above, according to the present invention, it is possible to provide a system construction apparatus, a system construction method, and a medium recording a system construction program, which enable high-speed and flexible processing with a single tool. it can.
