Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a CRT display device for simultaneously monitoring a plurality of status monitoring information and the like in a numerical control device.

[Conventional technology]

FIG. 5 is a block connection diagram showing a CRT display device added to a conventional numerical control device. In the figure, 1 is a processing device that processes and displays various information based on certain software (hereinafter referred to as CPU), 2 is a memory that stores the above software, 3 is a refresh RAM that stores each piece of information related to numerical control, etc., 4U
This is a CRT controller that displays the contents of the IJ fresh RAM on the CRT 5. In addition, refresh R
AM3 is addressed, for example, from O to 1999, which can display 80 characters x 25 lines, as shown in FIG.

Next, the operation will be explained.

Based on the software stored in the memory 2, the CPU inputs information related to numerical control etc. from the refresh RAM 3 to the tcRT controller 4 and displays it on the CRTs. By entering a predetermined character code into each address, that character is displayed on the CRTS at the position corresponding to these addresses.

The task of entering a character code into an address in the refresh RAM 3 is determined by software stored in the memory 2.

It is also possible to enlarge the characters displayed on the CRT5, for example, to adjust the size to any size you like, such as 2x, 3x,...'Xx. Whether such information is displayed is determined by the software created based on the purpose and specifications of the system.

[Problem that the invention seeks to solve]

Since conventional CRT display devices are configured as described above, the information displayed on the CRT screen is only one piece of information determined by the above software, and there is a limit to the amount of information that can be displayed on one screen. . That is, for example, in a numerical control device, many types of information are handled at the same time, and these are usually displayed on several to several dozen screens, but some of these screens contain information that you want to monitor at the same time. All information you want to view at the same time can be viewed on one CRTS
There is a problem that this selection operation is cumbersome.

Is this invention similar to the above? The objective is to obtain a CRT display device that can display information such as a plurality of images to be viewed simultaneously on the same screen.

[Means for solving problems]

The CRT display device according to the present invention has a plurality of information
It is stored in the recipe memory and divided into multiple split screens based on instructions by three fixed means.
The information selecting means selects and displays all of the information in the refresh memory, so that all different information can be displayed simultaneously on a plurality of split screens.

[Effect]

For example, the division designation means in this invention includes two CRTs.
Specify the number of divisions to make the screen into multiple screens, and based on this specified input, divide the CRT screen into multiple parts based on the CPU or certain software, and divide it in this way into one of the multiple split screens. First, the CPU executes display control based on software so that the information in each refresh memory selected by the information selection means is applied and displayed one by one. In this way, it operates to display a plurality of screens and images in one screen.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

In FIG. 1, 3a, 3b, and 3c are each fresh RAMs. For example, refresh RAM 3a is 80 characters x 25 lines, refresh RAM 3b is 160 characters x 50 lines, and refresh RAM 3C is 240 characters x 7.
It is a refresh memory capable of displaying each of five lines. Reference numeral 6 denotes a division command means for generating a command to divide the screen on the CRTS into a plurality of screens, and is provided on the keyboard or console in the form of keys or switches. Reference numeral 1 denotes information selection means for selecting and instructing information to be viewed from among the refresh memories 3a*3bT 30, and the CPUI displays predetermined information on a predetermined split screen based on the above-mentioned division command and selection command. Execute the processing for

FIG. 2 shows an example of the image division command means 6, which consists of nine parts, including a changeover switch dial 6a installed on a part of the keyboard, etc., and a division ratio display scale 6b.

Next, the operation will be explained.

Now, an operator of a numerical control device, etc., is
In the normal case where the information A on the screen 5A shown in FIG. It has become. Here, if the operator does not want to see all of the information B on the screen 5B shown in FIG.
/4. Then, first, the screen is divided into 5Atl/4, and information A is displayed in a reduced size on the divided screen above the main pressure, as shown in FIG. Next, operate the selection switch 1 as the information selection means 7 and select the screen 5B shown in FIG. 3.
When , the selected sentence information B is reduced and displayed in the upper right split screen as shown in FIG. Similarly, by selecting other information by the information selection means By, other information can be simultaneously displayed at the lower left and lower right of all the divided screens.

In the above embodiment, it is also possible to enlarge and display each piece of information A, B, etc. within the area of the split screen, making it possible to accurately recognize the monitoring target.

1. In the above embodiment, the display of information handled by a numerical control device was described, but the present invention can be applied to the display of all types of information in other devices.

〔Effect of the invention〕

As shown above, this invention divides one screen so that a number of pieces of information can be displayed simultaneously on nine or more split screens, so that information can be monitored simultaneously without averting one's line of sight. As a result, it is possible to carry out comprehensive state monitoring of numerical control devices and other control devices. Furthermore, the operator is freed from the troublesome work of selecting and displaying comparison information on the same screen, and has the effect of making the monitoring work of the operator more comfortable.

[Brief explanation of drawings]

FIG. 1 is a block connection diagram of a CRT display device according to an embodiment of the present invention, FIG. 2 is a front view of a changeover switch dial which is division designation means, and FIG. 3(a). Fig. 4 is a front view of the two screens, Fig. 4 is a front view showing the display state of a split screen, Fig. 5 is a block connection diagram of a conventional CRT display device, and Fig. 6 is a memory address configuration diagram of a refresh ram. be. 1 is a CPU, 2 is a memory, 3a, 3b, 3C are memory addresses, 5 is a CRT, 6 is a division specifying means, 7 is an information selection means, and 5A, 5B are screens. In addition, in the figures, the same reference numerals indicate corresponding parts.

Claims (1)

[Claims] CRT that displays different information on each of multiple CRTs
In the display device, there is a refresh memory storing each of the above information, a division specifying means for instructing the screen division of the CRT, and a division specifying means for instructing the screen division of the CRT, and a division specifying means for storing the information to be displayed on the plurality of divided screens based on the instruction in the refresh memory. A CRT display device comprising information selection means for selecting and displaying information from among them, and displaying different pieces of information on the plurality of split screens simultaneously.
