Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an input data change processing method in a data processing system having a data display device, and is particularly suitable for changing a large amount of input data later. Concerning input data change processing method.

[Conventional technology]

Traditionally, in process control and other computer systems,
This is when you try to change the input data.

The operator changes the input data etc. via the input device, but because we recognize that this may involve an error, the data entered by the operator is displayed once, and the operator cannot stop from the displayed content. If an error is discovered, there is often a means to change the error. In particular, when displaying graphics, a wide variety of input types are used in addition to character input, such as position input 1 graphic input, switch input 2 non-character numerical input, etc., so the input data input by the operator In order to display this to the operator, it is often expressed by appropriate characters or symbols, and when one figure is input, a specific symbol is displayed near the input figure, or the figure is displayed blinking. Hereinafter, the former representation using characters and symbols will be referred to as collective display, and the latter representation of figures themselves will be referred to as individual display.

[Problem that the invention seeks to solve]

Previously, the only way to change data that had already been input was to delete the last input data and re-enter it, and it was not possible to change only the data in the middle. Therefore, to change data in the middle.

There was a score of 4, as all subsequent data had to be deleted and then re-entered, increasing the number of operations and increasing the possibility of operational errors.

SUMMARY OF THE INVENTION An object of the present invention is to provide an input data change processing method that allows a player to correctly specify input data to be changed when attempting to retroactively change input data.

[Means for solving problems]

The input data change processing method of the present invention that solves the above problems includes an input device that can input information such as each piece of data and position change data that changes the position of the data, and a display that displays the given display information. In a method capable of changing input data of a device comprising: a device; and a processing device that processes information from the input device and outputs certain information as display information; A storage area is provided, and when there is input information from the input device, information regarding the type and display position of the input information is stored in the storage area, and when the input information is changed, the input to be changed is stored. The present invention is characterized in that when information is specified, the state when input from the input device can be reproduced on the display device based on the information from the storage area.

[Effect]

When the processing device takes in the information input from the input device, it processes the information and displays necessary information on the display device, and also stores information on the type and display position of the information in the storage area. When attempting to change input information, when the input information to be changed is specified, the state when input from the input device is displayed and reproduced based on the display information and information from the storage area. This allows you to change the input information correctly.

〔Example〕

An embodiment of the present invention will be described below based on the drawings.

FIG. 1 is a block diagram showing a process control system to which an embodiment of the input data change processing method according to the present invention is applied. In the figure, 11 is an analog input device, and 12 is an analog input device that converts analog data into digital data.
Digital converter.

13 is a digital input device. Reference numeral 21 denotes a processing device, which has means for storing a process manipulation program 22, an input data management program 23, and input position display information 24. , 31 is a display device for displaying characters and figures, 32 is a character input device such as a keyboard, and 33 is a position input device such as a tablet. Further, 41 is an analog output device, 42 is a digital/analog converter, 4
3 is a digital output device.

In Figure 1, the state of the process is indicated by analog input device 1.
1. The data read by the digital input device gi13 and the analog input device 11 are converted into digital data by the analog-to-digital converter 12, and the data read by the digital input device 13 are directly input to the processing device 21. The data is taken in and calculations are performed for process control. The calculation results are sent to the analog output device 41 after being converted into analog amounts by the digital/analog converter 42 for the analog control amount, and sent to the digital output device 43 for the digital control amount to control the process. .

Now, process control sometimes requires human (operator) intervention. For example, when an abnormal situation occurs, or when an operator is able to predict a problem or a better driving method based on his/her experience.

In such a case, the operator commands the processing device 21 using the character input device 32 or the position input device 33 that indicates the position on the display device 31.

Since the input of this command is a human operation, it is necessary to prevent erroneous input, and in this embodiment, this is achieved as follows.

This will be explained below with reference to FIG.

If there is input data from the data input waiting state (step 51), the type of input is determined (step 52);
In the case of character input 1 position input, the input data management program 23 transfers the contents to the process control calculation program 2.
2 (step 53), and echo-displays the input contents on the display device 31 (step 54);
Further, echo figures, echo order numbers, etc. necessary for later reproducing and displaying the input data echo are stored as input position presentation information 24 (step 55).

When the operator discovers an error in the input content, the operator
Use the cursor movement key 2 to position the cursor on the echo to be modified in the row of echo displays (step 5).
1,52.56). At this time, the input data management program 23 reads the entire content of the input position presentation information 2 (step 57) and displays it on the display device 31 in order to inform the operator of the input position on the screen corresponding to the echo under the cursor position. (step 58).

This allows you to easily specify the position input to be corrected.

FIG. 3 is a block diagram showing a graphic processing system to which an embodiment of the input data change processing method according to the present invention is applied.

In the graphic processing system shown in FIG. 3, 34 is an input data position changing device such as a cursor movement key on a keyboard;
5 is an input device such as a keyboard or a tablet. 2
1 is a processing device; 26 is an input processing program that receives input data from the input data position changing device 34 or the input device 35 and performs corresponding processing; 27 is six-input data inputted into the processing device from the input device 35; is the input device 35
31 is a display device that displays characters and figures to the operator; 25 is a display device 31 that displays characters and figures according to instructions from the input processing program 26; This is a display processing program that displays on the screen.

In graphic processing, generally, when an operator inputs a drawing command and parameters from the input device 35, the input processing program 26 receives them, performs graphic calculation processing, etc., edits graphic display commands, and performs display processing. The display processing program 25 displays the figure on the display according to this figure display command. In this series of processing, the input processing program 26 presents the contents of the input data to the operator and provides an echo display command corresponding to the input data so that the operator can easily determine that the input has been correctly performed. Edit and display processing program 25
Send to. This display command includes contents for both the collective display and individual display described above. The input data presentation information 24 necessary to fully (or partially) reproduce the echo display at this time is stored, and when changing the input data, based on this input data presentation information 24, This allows the operator to confirm whether or not he or she has correctly specified the input data that he or she wishes to change by reproducing the display contents when the input was first made.

An example of an operation when changing input data will be explained using FIG. 4.

In FIG. 4, 91, 92 and 93 are screen contents on the display device 31 during parameter input, 911, 9
12 and 913 are partial areas of the display device 310 used to present input data to the operator;
It is used for the batch display mentioned above.

Here, consider an operation for changing the line segments PIPz and PzPs to different colors. Screen 91 shows the state immediately before inputting two data A and B and inputting the third data. In addition, input data A is line segment Ps Px
Let it be a solid input. After inputting B, the line segment PxPt
To indicate that the line segment Pz Ps has been input, a special character may be displayed at a certain position on the line segment Pz Ps, or the line segment ptp,
A method such as flashing is used. This is the individual display mentioned above.

FIG. 4 shows an example in which the character 1 plus "is displayed.The screen 92 shows the screen after inputting C and D, where C is the color number of the line segment Ps Ps, and D is the color number of the line segment Pz.
The character 1 plus ° on the line segment PtPz is erased, and the character 1 plus ° is displayed on the line segment PwPs. Screen 93 is a graphic input by the operator from the state of screen 92. The figure shows a state in which the input data position change device 34 is used to specify the input data B to be changed in order to change the input data B after the death.The input data change position is indicated by an angle line in FIG. Here, when the input data position moves to input i, the angle line is displayed at the position of B, and the line segment pIPg which is the input figure corresponding to 1 input B is displayed as in the case of - plane 91.
The character "1 plus" is reproduced and displayed on the top, informing the operator that the line segment pt Px has been input by input B, and the character "1 plus" on the line segment P2P3 is deleted.

In this way, when changing already input data, when specifying the input data to be changed, it is necessary to fully or partially reproduce the state in which the input was made, and to make sure that there is no mistake in specifying the input data to be changed. Inform the operator.

Next, a more detailed explanation will be given with reference to FIG.

Consider the case where a rectangle is drawn after triangles Pi p and Ps are drawn. There are several ways to specify the drawing of a rectangle, but here we will specify the drawing of a rectangle by inputting three items: the length of the vertical side, the length of the horizontal side, and the center position. do.

It is assumed that the length of the vertical side is the length of the line segment PIF2, and the length of the horizontal side is the length of the line segment P, ps, and each line segment is input as a graphic. Screen 94 shows the state immediately after entering the line segment PIP* as the length of the vertical side, and screen 95 shows the state immediately after entering the line segment PsPs as the length of the horizontal side and F4 as the center position. .

In addition, the letters A, B, and C are line segments PtPz, P
This is a collective display corresponding to the input of 31 [1 of the Goose Pie personnel input P device. After inputting the center position indicated by input C, if you want to change the length of the vertical side from the length of the line segment ptP, to the length of the line segment PtPs, change the input data change position to A. Even if the setting is made, the screen 95 does not indicate which side the input person specified. Therefore, conventionally, the input A is based on the operator's memory.
It is determined that the line segments p, p, are input, and the input A is changed. This makes it more likely that you will make an incorrect designation than a memory error. In contrast, according to the embodiment of the present invention, when the input data change position is set to A as shown in screen 96, the input corresponding to the input person is the line segment P.
, Pz The character 1 plus " indicates that the line segment P
Since the information is displayed on the IPg, the possibility of making a mistake in setting the input data change position is greatly reduced.

Furthermore, according to this embodiment, it can also be used to reconfirm already input data, so the method will be described below with reference to Figure g6.

Here, consider a case where a quadrilateral is drawn by inputting four vertices. Screen 97 shows the state immediately after four points indicating each vertex have been input. Here, it is assumed that there is a constraint that the quadrilateral must be a convex figure.

In Figure 6, the four point inputs are pt l F2 *
P3. If it was input in the order of PIT F2, it would be a convex figure. F4. If input in the order of Ps, it will not be a convex figure. However, on the actual screen, even though a small dot may be displayed at the position of each point to indicate the input point, information indicating the input order is not displayed, so the points are placed in the order that forms a convex shape. With conventional methods, it is not possible to check whether the information has been entered. On the other hand, according to this embodiment, the input data change positions are changed to A, B,
C.

If you change D in order, the point input position corresponding to each input will be indicated by blinking dots, etc., so double check whether the input data has been input in an order that forms a convex figure. be able to.

FIG. 7 is a 70-chart showing a processing flow for realizing the above effect.

In step 71, the process waits until there is an input, and when there is an input, the process branches depending on the type of input: data input from the input device [35] or input from the input data position changing device 34. Step 7 for data entry
In step 3, input data is edited and stored, and in step 74, display commands for batch display and individual display are edited,
In step 75, this display command is sent to the display processing program 25 for display. In step 76, information necessary to reproduce the display result later is edited and stored as input data presentation information.

For example, when inputting a position, when inputting one coordinate value and a figure, the figure number is stored. At this point, the processing at the time of data input ends, and the system waits for input again.

On the other hand, in the case of input from the input data position changing device 34, the cursor position is moved according to the input content in step 77,
In step 78, the input data presentation information stored when the input data at the specified position was input last time is searched, and in step 79, this search content is edited and sent to the display processing program 25 so that it stands out to the operator. By displaying the data in a certain way, the display state when the data was last input is reproduced. For example, when inputting a position, a specific character such as character 1 asterisk (*) is displayed blinking at that position, and when inputting a figure, the corresponding figure is displayed blinking.After this, step 71 is performed again. The screen returns to and waits for input.

Now, if the above flow is described in correspondence with the operations shown in FIG. 5, it will be as follows.

The input B on the 1TjiJ plane 14 shown in FIG. 5 is edited and recorded in step 73 in FIG.
．． At 75, the characters "1 plus" and the characters 'A# on the screen 94 of FIG. 5 are displayed on the display device 31.

Furthermore, in step 76, the character data of the character "plus",
Stores information necessary to reproduce the execution results of display commands, such as display position and data order.

Next, when there is an input from the input data position changing device 34, the cursor position is moved in step 77, and the data input order value is changed, and in step 78, with this changed order value, The information already stored in step 76 is retrieved and displayed in step 79 according to its contents. Here, the state when the input data is input is displayed on the display device 31.

This is how it will be processed. Details of the processing contents of steps 74, 76, 78, and 79 in FIG. 7 will be explained below with reference to FIGS. 8, 9, 10, and 11.

FIG. 8 is a flowchart shown to explain in detail the processing contents of step 74 in FIG.

In FIG. 8, in step 81, character codes of characters used for batch display are stored. Next, in step 82, a command for displaying the character of the character code stored in step 81 of @ is edited. The display position is determined by the batch display situation at that time. In step 83, it is determined whether the input type is a character, a position, or a figure. If the input type is a position input other than a character input, the process branches to step 84, and if it is a figure input, the process branches to step 85. Note that when inputting characters, individual display is not performed, so the text is skipped.

In step 84, the character code of the position input character is determined and stored. Also, if the input type is a figure, step 85
to memorize the character code for graphic input. Furthermore, in step 86, the input coordinate values when inputting one position and inputting two figures are stored. Finally, in step 87, a command for displaying the character of the position input character code or the batch display status character code at the position of the input coordinate value is edited.

FIG. MX9 is a flowchart shown to explain in detail the processing contents of step 76 in FIG.

In FIG. 9, the input order number is stored in step 88. In step 89, the input type (one character, one position, one figure) is stored. Moving on to step 90.

Here, the input type is determined. In step 90, if the input type is determined to be character input, the process goes to step 91, if the input type is determined to be position input, the process goes to step 92, and if the input type is determined to be graphic input, the process goes to step 93.
They each branch out. In step 91, the character code is memorized, in step 92, the input coordinate value is memorized, and in step 9
In step 3, coordinate values and figure numbers are stored. In step 94, the total length of the data stored in 1,<f blocks 8B, 89 and steps 91 to 93 is stored, and the process moves to the next step 95. In step 95, the data stored up to the previous step is collectively stored as input data presentation information.

FIG. 10 is a flowchart shown to explain in detail the processing contents of step 79 in FIG.

In FIG. 10, in step 96, the input order of parameters is determined from the cursor position. Next, step 97
Then, this input order number is searched for in the input data presentation information 24, and the length of the data corresponding to it is found. Finally, in step 98, data equal to the length of the data obtained in step 97 is extracted from the input data presentation information.

FIG. 11 is a flowchart shown to explain in detail the processing content of step 79 in FIG.

In FIG. 411, a determination is made for each input 4 in step 99. In step 99, if the input type is character input, the process is skipped without any processing, and if the input type is position input, the process goes to step 100.

When inputting figures, the process branches to step 101.

If it is a position input or a figure input, the character code is extracted in steps 100 and 101, respectively. Further, in step 102, the input coordinate value is extracted, and in step 103, a command for displaying the character of the extracted character code at the position of the input coordinate value is edited, and this is sent to the display processing program 25 in step 104.

According to the above-described embodiment, when changing a part of a plurality of parameters that have already been input, the content of the input parameter is displayed in addition to the input parameters themselves displayed on the screen. It is now displayed in such a way that it can be distinguished from the other.

Thereby, the target parameter can be specified reliably.

〔Effect of the invention〕

As described above, according to the present invention, there is an effect that input data to be changed can be specified correctly.
