Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention is applicable to factory automation systems (FA
In particular, it involves dividing the display screen of a display device into multiple areas using the multi-window function, running multiple programs at the same time, and matching the images that are the processing results of each program. The present invention relates to a method for displaying images simultaneously in a region.

<Prior Art> In the context of rising material prices and labor costs and a shift from mass production to high-mix, low-volume production, a production system that provides higher efficiency is required.

For this reason, a large number of processing cells including numerically controlled machine tool areas and mabots are installed, as well as a logistics system including automated warehouses and automated guided vehicles, and a central management system controls the operation of these processing cells and logistics systems according to the production schedule. schedule operation, logistics control), the operating status of each processing cell and automated guided vehicle, and the progress status of each processing cell.
Outputs to equipment, and also stores NC programs in a managed manner.
FA systems that perform other management (such as modification, deletion, transfer, etc.) have been put into practical use.

FIG. 5 is a schematic configuration diagram of such an FA system, with 10
A processing cell 1 has an NC device, a machine tool controlled by the NC device, a robot control device, and a robot controlled by the robot control device. 102
is a logistics system that includes an automated warehouse, an automatic guided vehicle, and a logistics control computer, and transports workpieces to predetermined processing cells or imports processed parts as appropriate.

Reference numeral 103 denotes a central management system for controlling the operation of each of the processing cells 101 and the logistics system 102, managing cannibal programs, and centrally monitoring abnormalities in accordance with a production schedule given from a host device (not shown); 104 is a central management system for each of the processing cells and the distribution system 102; , a local area network (LAN) that connects logistics systems so that they can communicate with each other.
). The main computer MC0M, subcomputer SC0M1 program file PFIL, etc. that constitute the NC device, robot control device, and central management system 103 of each processing cell 101 are each connected to the LAN 104 via one cable, and each Control commands and data are transferred between units, and each processing cell performs machining according to the production schedule based on the management of the central management system. In addition, in parallel with these processes, the operation record diagram, production record diagram,
When displaying an overall view of the FA system, an enlarged view of a processing cell, etc. is required, the main computer MC0M or subcomputer SC0M displays each processing cell using operational data, performance data, and other data that can be updated in real time. The operation record table (Figure 6 (A)), the production record table (Figure 6 (B)), the overall diagram of the FA system (Figure 6 (c)), the enlarged view of the processing cell (Figure 6 (D) )) etc. are created and displayed on the display device 11cRT. The overall diagram displays the layout of all processing cells, automated warehouses, etc., and also indicates by color coding whether each processing cell is in operation, stopped, or down due to a failure. The enlarged view of the processing cell displays the layout of the machine tools, robots, NC devices, robot control devices, etc. that make up the processing cell, and also displays the operating status of each element by color.

<Problems to be Solved by the Invention> Incidentally, in conventional FA systems, only desired images are displayed on the entire screen in response to a request. for example,
When there is a request to display the operation results table, an operation results table is created and displayed on the screen of the display device, or when there is a request to display the overall view of the FA system, the overall view is created and displayed on the screen, and other alarms are generated. If there was a request to display a message image, an enlarged view of a processing cell, a production record table, etc., each image would be similarly created and displayed on the screen.

For this reason, in conventional systems, it is not possible to view multiple related images at the same time, such as the images shown in Figure 6 (A) to Figure 6 (D), and the overall status of the FA system cannot be viewed at a glance. I couldn't figure it out.

From the above, an object of the present invention is to provide an image display method in an FA system that can display a plurality of images simultaneously on one screen.

Another object of the present invention is to provide an image display method in an FA system in which the position or size of a display area where a desired image is displayed can be changed by key operation.

Means for solving problems〉 The display screen of the display device included in the central management system is divided into multiple sections, each divided display area is made to correspond to each of the multiple programs, and each program is run concurrently. The processing result of each program is displayed simultaneously in the corresponding display area.

Effects> The computers that make up the central management system are equipped with a multitasking function that allows them to execute several tasks simultaneously, and they are also equipped with a multiwindow function that allows them to perform multitasking on a single terminal (display screen). Have it. Then, the display screen of the display device is divided into a plurality of sections by the multi-window function, and each sectioned display area is made to correspond to each of the plurality of programs.

A computer uses a multitasking function to simultaneously execute programs, and uses a multiwindow function to simultaneously display processing results of each program in corresponding display areas. Furthermore, the computer changes the size and position of each display area based on a request using a multi-window function, and displays a predetermined image in the changed display area.

<Example> Fig. 1 is an example of a display image according to the present invention. The display screen of the display device CRT is divided into four parts, and each display area (window) Wl to W4 has an operation performance graph and an FA system's display screen. An overall view, an enlarged view of the processing cell, and a graph of production results are displayed. Each window Wi (i=1~
The position and size of 4) can be changed by equipping the computer with a multi-window function. That is, a predetermined image can be enlarged/reduced and the display position can be changed by an operator's key operations as appropriate. still,
The position and size of each window are shown below.

/W2'', the area indicated by I[I in the upper right corner of FIG. 2 is secured as window W2.
Window W1 can be closed by setting ET O,0,0,O,>7w1. In addition, W1'' and "W2" each represent the output designation of the I/-0 device. In other words, a program that runs concurrently using the computer's multitasking function specifies the I10 device name and outputs the processing result. The image is displayed in a predetermined window as shown in FIG.

FIG. 3 is an explanatory diagram of the image display method according to the present invention, and FIG. 4 is a flowchart of the process. In addition, as shown in Figure 1, 1
The two screens are divided into four windows W1 to W4, and each window displays an operation results table, a production results table, an overall view of the FA system, and an enlarged view of the processing cell, and the size and position of each window Wi. It is assumed that has already been set, and also input the program that creates the operation results table, the program that creates the production results table, the program that creates the overall diagram, the program that creates the enlarged view of the processing cell, and the correspondence between each window. shall be.

By providing a computer of the central management system, for example, a subcomputer SCOM, with a multitasking function, the above four programs are executed simultaneously. As a result, each image created by each program is
The data are stored in both first memories IMi (i=1.2.3.4) in the figure, and are sequentially updated as time passes. Incidentally, the first image memory IMi is the size of the display screen.

It has a size corresponding to

Next, the image stored in the first image memory IJIM is multiplied by 81, and the obtained reduced image is stored in the second image memory IJIM.
Gi (see Figure 3).

After that, check whether the reduction process of the image that should be displayed in all windows has finished, and if it has not finished! Repeat the above reduction process as +1 → l, and if completed, each second
The reduced images stored in the image memory TMGi (i=1.2, 3.4) are combined and stored in the screen memory IDM. Incidentally, when compositing, each reduced image is stored in the area on the screen memo IJIDM indicated by the position data of each window.

When the composite image is stored in the screen memo IJIDM, the image is read out from the screen memory and displayed in synchronization with the beam scan of the cathode ray tube.

Thereafter, the above processing is performed, and the latest images are displayed on one screen at the same time.

If a change in the position and size of the window is requested by key operation in such a state, the above processing is performed based on the new window size Lx, Lv and position to enlarge each displayed image. , reduction, ref)・
will be done.

Note that although the above is a case where the operation performance table, production performance table, overall view, and enlarged view of the processing cell are displayed as a related image group on one screen, the present invention is not limited to such a case. For example, since the computer in the central management system performs centralized abnormality monitoring, images that display the details of the abnormality in advance, enlarged views of the processing cell where the abnormality has occurred, etc.
Set up windows in a program so that the overall view of the FA system can be displayed simultaneously on the screen, set the windows in the program when an error occurs, and then use the multi-task and multi-window functions to display each image. 1
It can also be configured to display on two screens at the same time.

<Effects of the Invention> As explained above, according to the present invention, the display screen of a display device is divided into a plurality of sections, each divided display area is made to correspond to each of a plurality of programs, and each program can be run simultaneously and in parallel. Since the system is configured so that the processing results of each program are displayed simultaneously in the corresponding display area, the overall status of the FA system can be grasped at a glance, and operability can be improved.
