Abstract

PURPOSE:To enable an operator to accurately input an input signal name into a different drawing without storing nor writing down the signal name by storing the signal name in an area different from the store area of the circuit diagram data and then inputting the signal name into a circuit diagram under editing. CONSTITUTION:When a signal line through which a signal name is inputted is connected to a symbol equivalent to a connection symbol set to a different drawing or an instruction is produced to store the signal name, the signal name is stored in an area different from the store area of the circuit diagram data and then displayed. Then the signal name is inputted into a circuit diagram under editing with an input instruction and then erased out of the stored area with an erasing instruction. Therefore the operator is just required to input the displayed signal name into another drawing as it is. Furthermore a circuit diagram input device is either not required to store the circuit diagram data on plural drawings at one time. Thus the operator can accurately input the signal name in a short period without storing nor writing down the signal name.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a circuit diagram input device and a circuit diagram input method for inputting symbols of various parts, signal lines, etc. onto a circuit diagram using a CAD system.

[Prior Art] Conventionally, in a circuit diagram input device such as the one described above, when inputting a signal name input on a certain circuit diagram to another drawing (also referred to as a "schematic diagram page"), an operator inputs the signal name. Either memorize it or write it down as a memo, close the drawing you are currently editing, open another desired drawing, and enter the memorized or written signal name on the circuit diagram in that drawing. Was.

It also has the ability to display multiple drawings at the same time (
With a circuit diagram input device equipped with a multi-page editing function (referred to as a multi-page editing function), it was possible to simultaneously open and input multiple drawings in which signal names were to be input.

Problem to be solved by invention C] However, when inputting a signal name input on a circuit diagram to another drawing as described above, if the operator memorizes the signal name and inputs it, it may lead to memory errors. When inputting the correct signal names, errors in circuit diagram design can occur, and if the signal names are written down each time, the efficiency of the circuit diagram becomes inefficient.

In addition, when using a circuit diagram input device equipped with a multi-page editing function, input errors due to the operator's memory errors are eliminated; however, in order to display multiple drawings at the same time, multiple circuit diagrams In addition to requiring a large amount of memory capacity to hold data, the processing load on the control device (CPU) increases, resulting in slow response and poor processing efficiency when inputting circuit diagrams. there were.

This invention was made in view of the above points, and allows an operator to input signal names on a circuit diagram into another drawing quickly and accurately without having to memorize or write down the signal names. The purpose is to enable the input and to prevent the processing load on the circuit diagram input device from increasing at that time.

[Means to solve the problem]

In order to achieve the above object, the present invention uses symbols corresponding to parts constituting a circuit diagram, connection symbols to other drawings, etc.
In a circuit diagram input device that has an editing function for inputting, moving, and deleting the signal lines that connect the symbols and the signal names for each signal line, the input signal name is stored in the circuit diagram data storage area. means for saving in a different area, means for displaying the signal name saved by the means, means for inputting the saved signal name into the circuit diagram being edited, and erasing the saved signal name from the storage area. This means that a means has been established.

Also, when editing the signal name of a signal line connected to a symbol that corresponds to a connection symbol to another drawing on the circuit diagram, the signal name saved in an area different from the area where the schematic data is saved will also be edited at the same time. It is a good idea to provide a means for editing.

Furthermore, when inputting a signal name on a circuit diagram, if the signal line into which the signal name was input is connected to a symbol that corresponds to a connection symbol to another drawing, or if an instruction to save the signal name is given, Save and display the signal name in an area different from the save area of the circuit diagram data, enter the signal name on the circuit diagram being edited by inputting the saved signal name, and delete the saved signal name. A circuit diagram input method is provided in which a signal name is deleted from a storage area according to an instruction.

In addition, when you edit a signal name on a circuit diagram using the above circuit diagram input method, if the signal line whose signal name was edited is connected to a symbol that corresponds to a connection symbol to another drawing, the circuit diagram data It is a good idea to edit the signal names saved in an area different from the storage area at the same time.

[Function] The circuit diagram input device and its circuit diagram input method according to the present invention check whether the signal line into which the signal name has been input is connected to a symbol corresponding to a connection symbol to another drawing, or whether there is an instruction to save the signal name. When the signal name is saved and displayed in a different area from the save area of the circuit diagram data, the signal name is inputted on the circuit diagram being edited by the input instruction, and the signal name is The name will be deleted from the storage area, so
The operator only needs to input the displayed signal name as is into another drawing, and the device does not need to simultaneously save circuit diagram data for multiple drawings.

In addition, when you edit a signal name on a circuit diagram, if a signal line with that signal name is connected to a symbol for connection to another drawing, the saved signal name will also be edited at the same time, so the operator can input instructions. less.

[Example] Hereinafter, an example of the present invention will be specifically described based on the drawings.

FIG. 2 is a block diagram showing a schematic configuration of a circuit diagram input device according to the present invention.

This circuit diagram input device includes a keyboard 1 equipped with various input keys as input devices, a mouse 2, a storage device 3 for storing various data such as a hard disk device or a floppy disk device, and a display device such as a CRT or LCD. Device 4 and CPU.

It consists of a control device 5 equipped with a microcomputer configured with ROM, RAM, etc.

The keyboard 1 is used to input character information such as signal names and various work instructions, and the mouse 2 is used to input symbols such as connection symbols to various circuit parts and other drawings, and signal lines connecting each symbol using the mouse cursor. , and their signal names, etc., on the circuit diagram, or move or delete them.

The storage device 3 stores circuit diagram data and the like, and the control device 5 controls the entire circuit diagram input device and performs various processes related to circuit diagram input.

FIG. 1 is a functional block diagram of the control device 5 shown in FIG. 2, and the control device 5 is provided with each of the functions A to D for realizing the present invention.

Next, a process for inputting a signal name on a circuit diagram to another diagram will be explained using the flowchart of FIG.

For example, if the signal name rDATAAll is input to the signal line X on the circuit diagram, the signal name rDATA IJ is input to the signal line
The signal line X is added to the circuit diagram data storage unit as a signal name, and it is determined whether the signal line X is connected to a symbol representing a connection to another drawing (connection between pages). Or, if the signal name save command (instruction) is issued (input) even though it is not connected, the signal name rDA
TA1'' is saved in an area different from the circuit diagram data and displayed on the display screen.

If it is determined that there is no connection and the signal name save command is not issued, other processing is performed and the process ends.

After displaying "Signal Name rDATA1", if the operator instructs to open another drawing, the page of the drawing currently being edited is finished and closed, and the page of the other instructed drawing is opened and displayed.

Next, when the signal name restoration command is issued, add the saved signal name rDATAIJ to the area where the circuit diagram data is stored and display it on the circuit diagram, and if it is not issued, perform other processing. Finish the process.

After that, when the signal name deletion command is issued, the signal name rD saved in an area different from the area where the schematic data is saved is deleted.
The process ends when ATA IJ is deleted and its display disappears.

Next, a procedure for inputting a signal name on a circuit diagram to another drawing and an example of its display will be explained with reference to FIGS. 4 to 9.

Figure 4 shows a screen 5 during circuit diagram editing, with a work area 6 for displaying the circuit diagram being edited and the saved signal names in an area different from the area where the circuit diagram data is saved. Menu 7 for editing the circuit diagram, and commands for displaying various work commands such as symbol insertion 8a, signal line insertion 8b, signal name insertion 8c, signal name save 8d, signal name deletion 8e, and signal name restoration 8f. A column display area 8 is displayed.

Symbol insertion 8a is used to input and place symbols representing circuit components in the work area 6, signal line insertion 8b is used to input signal lines connecting each symbol, and signal name insertion 8c is used to input signal names. The save signal name 8d is used to save the signal name and display it in menu 7, the delete signal name 8e is used to delete the saved signal name and remove it from menu 7, and the restore signal name 8 is used to display it in menu 7. This is a command to extract the displayed signal name and input it onto the circuit diagram.

Currently, work area 6 includes AND gate 9 and amplifier circuit 1.
0 is connected by a signal line LY, and a connection symbol 11 representing a connection between pages is connected to a signal line LX extending from the amplifier circuit 10, and near the AND gate 9 and the amplifier circuit 10. Each symbol's text rLs
O8J rLS04J is also displayed.

From this state, the mouse 2 cursor (mouse cursor)
Align it with signal name insertion 8C, click the mouse button, specify the position to input the signal name with the mouse cursor,
Enter rDA as the signal name of the signal line LX using the keyboard l.
When TAIJ is input, connection symbol 1 is displayed as shown in Figure 5.
Signal name rDATA1” at the indicated position on the right side of 14
is displayed.

Next, when the mouse cursor is placed on the signal name save 8d and the mouse button is clicked, the signal name rDATAIJ 14 is saved and displayed on the menu 7 as shown in FIG.

After that, close the current drawing and connect the signal line LX extending from the connection symbol 12 to AN in another drawing as shown in FIG.
When the page containing the circuit diagram data connected to one input terminal of the D-gate 13 is displayed, the signal name "rDATA1" 14 is still displayed on the menu 7, and the mouse button is pressed on the signal name return 8f. Position the cursor and click the mouse button, then move the mouse cursor to the side of connection symbol 12 and click, the signal name rDATAIJ will appear at the mouse cursor position as shown in Figure 8.
14 is input and displayed.

Then, when the mouse cursor is aligned with signal name deletion 8e and the mouse button is clicked, the signal name rDATA IJ14 that was saved and displayed on the menu 7 is deleted.

Note that this signal name deletion command 8e is valid whenever a signal line name is displayed on the menu 7.

Next, another embodiment will be described. The configuration of the circuit diagram input device of this embodiment is the same as that shown in FIG. Unlike the example, for this purpose, the control device 5 is equipped with means E to G shown in the functional block diagram of FIG.

FIG. 11 is a flowchart showing processing related to automatic storage of signal names in this embodiment.

When the operator inputs rDATAIJ as the signal name of signal line If so, signal name rDAT
The AIJ is saved in a different area from the circuit diagram data, displayed on the screen, and the process ends.

Furthermore, if there is no connection, the process ends immediately.

Therefore, in this embodiment, when the signal name rDATA1 14 is inputted to the signal line LX shown in FIG. 4, the connection symbol 11 of the symbol indicating the connection between pages is connected to the signal line LX, As shown in FIG. 6, the signal name rDATA IJ is input and displayed on the side of the connection symbol 11, and the signal name 1"DATA 1
”14 is saved and displayed on menu 7. At this time, the signal name constitutes the circuit diagram data as data belonging to the signal line.

In this way, even if you do not issue a command to save a signal name, if a symbol representing a connection between pages is connected to the signal line where you entered the signal name, the signal name will be automatically saved. Since the information is saved, the number of commands to be issued is reduced, and the efficiency of the circuit diagram input operation can be improved.

It should be noted that there is no problem even if other commands are executed during the procedure for inputting a signal name into another drawing mentioned above.

Also, if you enable input within the same page rather than to another drawing, or if you can save multiple signal names, when inputting the same signal name on different pages (or even the same page), It is convenient to be able to select the signal name from the menu.

[Effects of the Invention] As explained above, the circuit diagram input device and the circuit diagram input method according to the present invention display the signal names on the circuit diagram in another drawing, and the displayed signal names are used as they are in the circuit. Since the signal name can be input on the drawing, the operator does not have to memorize or write down the signal name, and can input it accurately into another drawing in a short time.

Furthermore, since it is not necessary to display a plurality of drawings at the same time, the memory capacity used is small, and the processing load on the circuit diagram input device at that time does not increase.
