Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a Kameko computer system (hereinafter referred to as a computer system), in particular, which provides functions equivalent to that of a Kameko computer system even when an operator console is not connected. [Technical Background of the Invention] A computer system that performs various types of plant control includes an operator console, a CRT display device, and a man-machine interface with the operator. Generally, the console is equipped with a process input/output device for inputting and outputting information to and from the console. This computer system records control information for controlling the plant, and a control processing program controls the plant according to the control information, but changes to this control information and control processing program are inevitable. It is done as often as possible. This is due to changes in plant control methods and the addition of control functions.

Control 'lb' for the computer system that has started operation
When changing information or adding control functions, control using the computer system currently in operation (4) Since it is not possible to change the guy bag of the processing program or change the control information, it is necessary to use another computer for maintenance such as changes. The system (hereinafter referred to as the house machine) debugs the control processing program and changes the control information.Debugging means finding and correcting errors in the program. A machine usually refers to equipment commonly used in computer systems, such as a central processing unit.

It consists of an auxiliary storage device, an input/output typewriter device, a CRT display device, a line printer device, a card reader device, etc., and the operation console with nine different functions depending on the computer system is currently not connected. .

Here, an example of a debugging method using a house machine will be explained with reference to FIG. In Figure 1, 1 indicates a computer system, and the central processing bag? It consists of M'2 and an auxiliary storage device 5. The medium heat treatment device 2 is composed of an arithmetic and control device 3 and a main storage device 4. Furthermore, the main storage device 4 contains a console control processing program 8 and a plant control processing program 9 that perform two control processes. It will be done.

Further, in the auxiliary storage device 5 in the computer system 1, there is a control information file 10 that is accessed by the plant control processing program 9. In addition, there is an operator console 7 which is a man-machine interface between the computer system and the operator, and a process input/output device 6 through which an operator console control processing program 8 serves as a medium for inputting and outputting information to the operator console 7.

The portion of the above computer system 1 excluding the process input/output device 6 and the operation console 7 is considered to be the configuration of a 7-US machine.

Figure 2 is an outline drawing to illustrate the functions of the operation console.Since most recent operation consoles consist of a CRT display and buttons, we will use that configuration as an example. Try opening the functions of the control console.

(1) When a button is pressed, the CRT screen corresponding to that button is displayed.

(2) Turn on the button lamp when an abnormality occurs in peripheral equipment, etc.

(3) If a peripheral device is in use, turn on the wholesale lamp corresponding to that peripheral device.

(4) If an abnormality occurs in an item monitored by the divider system, the lamp of the corresponding button will be lit.

For example, in a computer system that monitors the voltage of an electric power system, if the voltage value exceeds a limit, the lamp on the button labeled ``Heavy Pressure Abnormality'' will light up on the console, and the operator will be notified of the abnormality. It's the kind of thing that lets you know something has happened.

[Problems with background technology]

As mentioned above, the operation console has various functions, but for example, it is useful for debugging the program when adding functions to the plant control processing program 9 that is activated when a button on the operation console 7 is pressed. The debugging person must think about and set the same data on the calculator as when the operator console 7 is pressed. When making these settings, there will be no problem if this is simple data, but normally these data are created by the console control processing program 8 based on each of the 41 control information on the condition that a button is pressed. This data is often complex. As a result, debugging and testing functionality equivalent to normal operation requires a great deal of effort and time. Furthermore, when adding the function of the console control program that operates to input and output information to the console 7 via the siprogram input/output device 6 by the console control zologram 8, since the console 7 is not present, the original There are many things that Devanog can do.

In short, the absence of a console, which is a man-machine interface with the operator of the computer system, means that it is not possible to perform diagnostics and tests that are equivalent to normal operations.

[Purpose of the invention]

The present invention was made with the aim of solving the above problems, and in addition to changing control information and establishing control functions, it is possible to perform the same functions as in normal operation even if the console is not connected. Not only can debugging and trial construction be carried out, but the TL and test range are not limited.
'The purpose is to provide a computer system control method.

[Summary of the invention]

In the present invention, console connection state specification data and a simulated data setting area are provided in the main memory, and when the console is connected to a computer system, information is input and output to the console, and the console is If it is not connected, an attempt is made to input and output information to the simulated data setting area, which has information equivalent to the information to the operator console.

[Embodiments of the invention]

Examples will be described below with reference to the drawings.

FIG. 3 is a configuration diagram of an embodiment of the computer system control method according to the present invention. Reference numerals 1 to 10 in the figure correspond to those in FIG.

In addition to the above, the main storage device 4 also contains operator console connection specification data 11 for determining whether or not the operator console is connected to the computer system, and a simulated computer that has information equivalent to input/output information to the operator vehicle. There is a data setting area 12.

FIG. 4 is a flowchart of the operation vehicle control processing program when a button on the operation console is pressed, and the normal control processing will be explained using this flowchart.

First, in the stem game Fl, a process input/output request is made to input the state of the button on the console.

When making a process input/output request, a process input/output request subroutine is generally prepared and this subroutine is called by the requesting program.

This is a common subroutine within the computer system 1, which inputs and outputs information from the operator console 7 according to the request of the calling side, and returns it to the calling side.

In step F2, the content of the request from the console 7 is determined based on the information returned from the subroutine, in step F3 data for the plant control processing program 9 is created, and further in step F4, the plant control processing is performed. Start program 9. The activated plant control processing program 9 controls the plant based on the data created by the console control processing program 8 and the data in the control information file 10.

FIG. 5 is a flowchart of the process input/output request routine used in the console control processing program.

First, in step F5, process input/output request parameters (data specifying a control target) are extracted. Next, in step F6, the preset operator console connection state specification data 11 is referred to, and if the operator console is specified to be connected to the computer system, the process moves to step F7. Input information on the console 7. Here, if the operator console 7 is specified as not being connected, move to Stella fFs and enter information in the simulated data setting area 12 having information equivalent to that of the operator console 7. Then, in step F9, the input information is returned to the console control processing program 8 that called this subroutine. Note that the above-mentioned Stella fF6 and F8 are newly added this time.

The method of setting data in the simulated router setting area 12 after changing the console connection state specification data 11 is to change it directly from the input/output typewriter device, or to change it directly from the input/output typewriter device.
Various methods can be considered, such as a method of changing depending on the type of interaction with the display device, but detailed explanation will be omitted since this is not the gist of the present invention. Although the above explanation mainly deals with the input side of process input/output, the same applies to the output side.

The simulated data setting area 12 described here is
Since the configuration corresponds to the button arrangement, in other words, the bit arrangement of the digital human power module in the process input/output device 6, it is easy to set information corresponding to the buttons on the operation console 7.

Furthermore, although only an operation console has been described here, it goes without saying that the present invention can also be applied to a controlled transmission controlled by a computer system.

[The moving bed of invention]

As explained above, according to the present invention, it is determined whether or not a console is connected to the computer system, and if it is connected, information is input/output to the console, and if it is not connected, information is input/output to the console. is configured to input and output information to the simulated arrest data setting area, which has the same information as the information sent to the operator console, so the operator console can be connected even in a computer system to which no operator vehicle is connected. It is possible to efficiently carry out guy bags and tests equivalent to those of , improve productivity during maintenance, and ensure the quality of the computer system.
