Abstract

PURPOSE:To secure and attain efficient operation by making only the operation from one keyboard available and removing the useless occupation of a central processing unit (CPU). CONSTITUTION:A CPU1 and a memory are connected to a bus, and display devices 51, 52-5n incorporated in a CRT-mounted operator consoles 41, 42-4n through display controlling devices 31, 32-3n, and keyboards 61, 62-6n are also connected to the bus through a controlling device. When the same picture is displayed on plural display devices, only one master operator console having a CRT is designated for the displayed information, and other operation consoles having CRTs are used as local operator consoles, so that only the keyed-in data from the keyboard mounted on the master operator console having a master CRT are effectively inputted to the CPU1.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a display device with a plurality of keyboards connected to a computer, or a CATHODE RAYTUB.
The present invention relates to a method for managing key-in data settings in an operator console with B (hereinafter referred to as CRT).

It is well known that in a system in which multiple operator consoles with CRTs are connected to a computer, data is entered independently from each operator console by key-in operation. Also, for sending (e.g. 5E
Until the 5END key is pressed, it is only temporarily stored in the buffer memory of the control device and is not notified to the computer. Therefore, even if the key-in data is accumulated once, another activation condition may be set before the 5END key is pressed. When a CRT display update command is received from the central processing unit (called the CPU), the data in the buffer memory in the display control device is replaced with information corresponding to the command from the CPU. There is a drawback that the data accumulated in the device buffer memory is lost, and the key-in operations up to that point become invalid.

The present invention has been made to eliminate the above-mentioned drawbacks, and when the same screen is displayed simultaneously on multiple CRTs, one operator console with the main CRT for the displayed screen information is used, and the other CRTs are By defining the operator console as the sub-CRT-equipped operator console, only the key-in data from the keyboard attached to the main CRT-equipped operator console that is displayed on the screen will be valid for input to the computer, and other data will be valid. To provide a method for preventing confusion in data input by disabling input from the keyboard.

Embodiments of the present invention will be described in detail below with reference to the drawings. FIG. 1 is a block diagram showing the configuration of an embodiment of the present invention, including a central processing unit (CPU) 1. Memory 2 is connected to bus BUS K, and additional Kn CRT-equipped operator consoles 41.4
Home display device (CRT) 51 for 2 to 4 fl
．． 52-5n to display control device 31.32-3n
q, and the keyboards 61, 62 to 6n are connected together to the BU8k via a control device (not shown).

Figure 2 (illustration) and Figure 2 (b) are enlarged views of the keyboard 1°62 and have the same configuration, and the other keyboards 63 to 6n have the same configuration, so only the keyboard 61 will be explained here. .

In the figure, 71-1, 71-2 to 71-m are m screen calling keys, and when these keys are pressed, the corresponding screens GA1, GAt#GAm are called up, respectively. These screens are displayed using m double-sided call keys 72-1 provided on the keyboard 62 shown in FIG. 2(b).
．． When 72-2 to 72-m are installed, a process having a similar function is allocated to cPUli and memory 21C. As is well known, the information displayed on the CRT 51 must be stored in a buffer memory (not shown) in the control device 31kli'ffff1, but there are two storage paths; There is an input itself, and as a result of processing with the former CPU, the information stored in the buffer memory IC is already stored in the memory 2. However, the latter key-in input is processed as is.
The stored information is not processed by the CPU at the key-in stage, nor is it stored in the memory 2. Therefore, a means to notify CPUIK of key-in input is required, and
The END) button 91' is for that purpose. In other words, by inputting the data key 8'1 multiple times, data is stored in the backup memory at the foot of the control unit [31] without interfering with CPU processing.
After displaying the data, until the transmit (8END) button 91 is pressed, the screen information differs from the same screen information being displayed on other CRTs only in the key-in data. Send (5END) button 9
1' is carried in and sends a command signal to the CPU 1, for example, by interrupting, and then the CPU reads the buffer memory in the control device 31 into memory 2, and at this time, if there is another CRT that is currently displaying the same screen. The CRT display is also changed.

Now, the screen GA when the screen call key 71-1 is pressed
Assume that the display status of I is as shown in FIG. 3(a). FIG. 3(3) is an enlarged view of the screen of the CRT 51, and an area 511 surrounded by a dotted line is for displaying the screen number, and here 111 is displayed as indicating the GAI.

Areas 5j4, 515, and 516 are fixed items A I A2 AlA41 B I Bz, B 'B' on this screen.
g It displays variable data corresponding to C'C Snow CsCa. If there is data that should be displayed, it is displayed, otherwise it is blank. Area 512 is the currently displayed screen GA! Against L.
, displays which is the main operator console (this is also the main keyboard), and if we say that this screen GAl is the main operator console 41 (main keyball 61), this operator console is the serial number of all operator consoles φ. Since it is 1, %11 is displayed. Area 513 displays whether key-in data from this operator console (main keyboard) can be effectively transmitted to the computer for the screen G person IK being displayed.According to the above assumption, the main keyboard for screen WGAs is If so, 'YES' or %Yt is displayed in the area 513.

On the other hand, the CR provided on the operator console 42
At T52, when the same screen GA1 is displayed with the CPUI red and white, the area 521 is displayed as shown in FIG. 3(b).
has the double opening number 11#, and the area 524, 525, 52
6 contains the same information as areas 514, 515, 516.
The area 522 displays the serial number ``''II of the main operator console of the screen GAS, but the second area 523 shows 'NO' to indicate that setting data cannot be sent because this operator console does not match the main operator console. Or display as %NI.

The above explanation describes the case where 0 people and 1 screen (screen serial number 1) are displayed for the operator console 41842 (therefore, CRTs 51, 52, keyboard 61, e2), but the operator console 41.42 to 4m and screen 11G are displayed.
Even if Ax and GAm-GAm are changed in various ways, only the displayed numbers and characters will change, and the display will be performed according to the same rules.

If the main operator console for the image@QAs has not been determined, both the areas 512 and 522 in FIG. To notify CPUIK of key-in data, be sure to declare that the keyboard is the main keyboard on the screen (
(called the primary keyboard declaration).

The key-in operation will be explained in detail below.

Main operator console with current display on CRT 51. Therefore, when the main keyboard is undecided, if you want to use the keyboard 61 as the main keyboard, use the keyboard 61.
All you have to do is press the main keyboard button 91 provided on the main keyboard. As described later, the main keyboard declaration is established exclusively, and once this declaration is established, it is maintained until it is canceled.

To cancel the establishment of the primary keymate declaration, use the following method.

(1) Display the screen GAt on the CRT 51 and press the main keyboard declaration button 91 again to cancel the main declaration, press the main declaration button 91 again to make the main declaration again, and repeat the sequence. PUSHPU every
Release and declaration are performed sequentially using the SH method.

(2) Display the screen GAS on the CRT 51, operate the data key 81, and press the transmit (8END) button 91' after entering the necessary data.
The information being displayed on the CRT 51 stored in the internal buffer memory of No. 1 is transferred to the CPU
Cancels the establishment of the primary keyboard declaration in step 1.

The following restrictions apply to the operation of the send (8END) button 91'.

Information stored by operating the data key 81 (INF
! ) exists only in the display buffer in the control device 31 unless the send (5END) button 91 is pressed, and the input data up to that point (which matches the display information on the CRT 51) is not notified to the CPUI, so unless the content of the display buffer memory in the control device 31 is notified to the CPUIK in some way, CJP: U
"It is out of the control of 1. Therefore, send (8FiND) button 91
If you call up the screen on the CRT 51 without transferring it to the memory 2 by notifying the CPUI by operating the Therefore, the contents IN of the buffer memory in the control device 31 up to that time
F! is rewritten with this information INFl, and the operation of the key 81 becomes useless.

Regarding screen GA1, when the keyboard 61 has already been declared as the main keyboard, screen GA1 is
Even if the button 92 is pressed because the main keyboard declaration is 0 from the keyboard 62, the main keyboard remains the keyboard 61 and does not move to 62 as a result of exclusive control. The screen GAt is displayed on the CRT 52 in the operator console 42, the data keys 82 are operated to input data, the data is stored in the display backup memory in the control device 32, and the screen GAt is displayed on the CRT 52.
The screen information of SEN will also be updated accordingly, but the SEN
D) When button 92' is pressed to issue a command to the CPUI,
Since it violates the rules, it is processed as an error and is not transferred to the memory 2. % NI in area 523 in FIG. 3(b) informs the operator of this fact.

What has been described so far is an example in which the keyboard 61 is declared as the main keyboard for the screen GA1, but it goes without saying that the main keyboard can also be individually declared and released for the other screens GA2 to GAmK.

The input information of the key 81' cannot be input directly into the areas 511 and 512, but must be processed by the CPU. In addition, even if the keyboard 61 is declared as the main declaration for the screen GAI and the main declaration designation button 91 is pressed while the screen GA 1 (i key 1) is being displayed on the CRT 51, the main declaration for the screen GAIK is not canceled and the screen GAi Only the main keyboard declaration for is established. In other words, when canceling the main declaration, it is necessary to display the target screen and issue the cancellation command. In this example, the main keyboard declaration button 91 is PUSHPU8
The HP function has both declaration and declaration cancellation functions, but separate functions may be provided for designation and cancellation.

According to the present invention, it is possible to declare and release the keyboard according to the main operator console on the display screen, and as long as the main declaration is active, data can be set from the keyboard set on the main operator console that is displaying the screen. , data transmission is enabled, but data settings and data transmission from the keyboard provided on the slave operator console other than the main one that is currently displaying the screen are disabled, so when multiple CRTs are displaying the same screen using their respective keyboards. Even if the Cτ-data is set (independently), only operations from one keyboard are valid, eliminating unnecessary CPU occupancy, which has the effect of ensuring efficient operation.
