Abstract

PURPOSE:To reduce the man-hour for generation of a program, by storing prelimiarily a basic program package in a storage device, and designating the required number of these packages to generate the program. CONSTITUTION:A device stand-alone program package group 9 where device stand-alone programs are stored is preliminarily set to a storage device MEM. A plant simulating program generator 11 stores programs in a simulating program work area 12 in order on a basis of the group 9. Programs stored in the area 12 are inputted to a plant simulating program generator 13, and this generator 13 converts numbers of respective attributes of operand code parts of these programs to overall sequential numbers without disordering relative numbers of respective device stand-alone programs. A plant simulating program 14 obtained by this processing is stored in the device MEM. This program 14 is outputted to the external by a simulating program output device 15 of a CPU.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automatic program generation method, and more particularly, to an automatic program generation method suitable for generating programs for testing plant control devices and the like.

Computers that function as plant simulators are widely used, and can be used to check and perform performance tests on the control device itself without actually connecting Plan L or the controlled object, making it a safe testing method. It is said that

In explaining the automatic program generation method of the present invention,
The following is 11yt% (
The program generation will be explained using a plant simulator as an example.

FIG. 1 is a block diagram of a known plant control device.
In the figure, / indicates a control device, and μ indicates a controlled plant consisting of a pump P, a valve V, etc. In this configuration, the control device / indicates an answerback signal from the controlled plant. Upon receiving the status signal J, the control plan 4 is controlled by the control signal -. A performance test using a plant simulator for such a control device is as follows:
As shown in the block diagram of FIG. 2, the function of the control plant can be implemented by simulating it with a program such as a plant simulator. Here, since the control target plan) 4 is composed of a combination of individual plant equipment (pump P, pulp V, etc.), the program of plant simulator j is also a unit program element with functions corresponding to these equipment. It will be composed of a combination of.

However, Plant Siminire-I! The computer program constituting the software normally consists of an operation code part t representing the content of the operation, and its -
This is a collection of one instruction l composed of an operand code section 7 representing the object of the operation. In contrast, in the past, programs for all functions of a plant were created through field coding, etc., which required a tremendous amount of man-hours and hindered efficient operation.

Therefore, an object of the present invention is to (1) take advantage of the prior art, and when the function of a target program used in a program such as a plant simulator is expressed as a set of unit functions, the required type of program having the unit function is The present invention provides an automatic generation method for progera that makes it possible to automatically generate a program having a desired function by specifying the number and number of programs. In order to generate a program that simulates a function, instead of generating the entire program each time, we focus on the fact that the entire plant is a collection of small plant elements, and calculate the function of each plant element. Prepare programmed packages in advance, and create a program that simulates the entire plant by collecting the necessary types and number of program packages.Instead of trapping, the man-hours required to generate a program that simulates the entire plant can be reduced. The present invention provides an automatic program generation method that makes it possible to significantly reduce costs.

Hereinafter, the present invention will be explained in more detail with reference to the drawings.

#! The figure shows a block configuration diagram of a plant simulator to which the automatic program generation method according to an embodiment of the present invention is applied. A storage device consisting of a simulated programming system,
The OPU is connected to a seventh plant simulation program generation device l, a data processing device including a second plant simulation program generation device 13, a plant simulation program output device 15, etc.;
MT is a cassette magnetic tape which is an example of a program output medium to the outside, and LP is also a line printer.

In this configuration, the storage device 11Mm+iM is preset with a group of device program packages in which device program packages are stored, but this includes an operand code section as shown in the schematic diagram of FIG. 17 is a set of device unit programs numbered sequentially from 0 according to their attributes. Each operation in Figure 3;
The meaning of - code 16 is as shown in Table 1, and the meaning of each attribute of each operand code l) is as shown in Table 1.

In this program, even if the numbers of each operand are biased, the function of the program is the same as long as the relative order of operands with the same attribute is the same.

On the other hand, the first plant simulation program generation device// generates a plant simulation program in order from a group of equipment program packages according to the type and number of equipment program packages specified by an external operation signal l0VC. Store in area/co. At this point, the operand code portion of the plant simulation program remains as shown in FIG. 3, and the numbers for each operand attribute are duplicated.

Next, the number of man-hours for creating the first plant simulation program is 13.
The program stored in the Plan Nu pseudo program work area/JK is converted into a number that runs through the entire program as input so as not to deviate. What is obtained by performing such processing is the Plan II program.

Here, an example of a specific process is shown in the explanatory diagram of FIG.
As is clear from Figure 1, when the first plant model program generation system is busy, programs 1 and 1 are sequentially transferred to the plant simulation program work area from the device program package group. Can be stored. At this point, the numbers for each operand attribute in the operand code portion of the program are not sorted and are still read from the single device program package group D. In the program of the plant simulation program work area/J, the number for each operand attribute in the operand code section is converted into an overall serial number by the first plant simulation program generation device 13, and the numbers for each operand attribute are organized so that there is no duplication. The program is then stored in the storage device M1nM as a plant simulation program lq.

The program lt generated as described above is transmitted to the plant simulation program output device/
jk to the outside, but this is output as a program code to a cassette magnetic tape OMT that is a medium, or as a program list to a line printer LP.

As described above, by implementing the present invention, the basic program package can be stored in a storage device in advance and generated as needed, instead of the conventional method of generating the entire program each time through coding etc. By specifying the necessary number of them, it becomes possible to automatically generate all programs, and therefore the effect of reducing the number of program creation steps is enormous.

Although the above embodiment has been described by taking as an example the generation of a program for plant simulation I for testing a plant control device, the implementation of the present invention is not limited to this.
It goes without saying that similar effects can be obtained with other general program generation.Furthermore, in the configuration of the above embodiment, the output medium of the program is a cassette or magnetic tape OM? Or line pre/ri LP
However, even if other media such as OR'r are used, the effects of the present invention will not change.
