Procedure for acknowledging on the screen of a Analog display device displayed messages from a control center. ·. . .

Alphanumeric displays are often used to Data, e.g. texts, in a control center, usually a data processing system, to enter. For this purpose, the texts are first entered using a keyboard on the screen of the Display device and then from the beginning of the first line to an end character to the data processing system transfer. Texts from the data processing system can also be read via display devices are issued. Especially when using display devices in process computer systems it is often desirable to have messages that were issued by the data processing system and that were each in a Line are accommodated, to be acknowledged positively or negatively. This is with the usual units for entering Data in the data processing system not possible.

A simple way of acknowledging individual messages would be to provide two keys for positive and negative acknowledgment for each line of text and to enter the resulting acknowledgment signal into the data processing system, specifying the key or line number. Such a solution has the disadvantage, however, that an additional transmission channel is necessary for the acknowledgment signals and that, therefore, at a greater distance. A great deal of effort is required between the display device and the data processing system. Also, a large number of lines of text that are to be provided for the two keys would require a major effort.

The present invention is based on the object of creating a possibility for acknowledgment signals via to send the same transmission lines to the data processing system as the others supplied by the display device Input data. This object is achieved according to the invention solved that a mark reproduced on the screen by means of a marking unit, which a Contains position counter for the line, the content of which determines the line in which the by changing the counter content A mark that can be moved above the screen is displayed in the line in which the message to be acknowledged is displayed, is pushed that then the content of the position counter and by pressing a Acknowledgment signal generated by the key in an output register taken over and transferred from there to the control center. Such a procedure can be based on the screen the label can be determined directly which message is being acknowledged. The quIgtierungssignal is then Delivered to the head office stating the line number. Since the acknowledged message comes from the control center and from if the line in which the message was written was specified, the acknowledgment signal can be sent in the control center assigned to the acknowledged message based on the line number. You can also use a Marking unit of the type are used as described in the earlier application P 18 17 227.5 is. Such marking units contain a positioning unit, for which, for example, commercially available trackball devices or joysticks can be used. With the roller ball device, a freely movable ball can be turned by hand in all directions. Be there the rotary movements via two friction wheels offset by 90 °, each of which has a coordinate of the screen image are assigned to signal transmitters, e.g. to optical or magnetic pulse transmitters. With the positioning unit pulse generators can also be coupled, the pulses of which in two electronic up and down counters

learn to be summed up. The contents of the counters "■■ indicate the both coordinates of the marked point. The two Counters are also known as line and digit counters, because one counter is the line and the other is the line. position within the line in which the mark is to be displayed. To generate the brand you can E.g. * be connected to the two counters digital-to-analog converters, which at time intervals control the deflection systems feed the picture tube, at the same time a light button signal is emitted. It is also possible to change the content of the line memory with that of a line counter and the Compare the contents of the position memory with that of a number of positions. The line counter is set to zero at the beginning of the display of each image and increased by one when each line is scanned. The position counter is set to Hull at the beginning of the display of a line and counted up with the pulses of a clock generator. If the content of the line counter is the same as that of the line memory and the content of the digit counter is the same that of the position memory, then a light button signal submitted.

If the mark is a luminous point, the light button signals can the digital-to-analog converter or the circuits comparing the counter and memory contents directly can be used to control the electron beam of the picture tube. Often, however, is a single marked pixel cannot be seen clearly enough. It is therefore advisable not to depict a single point, but rather a symbol, e.g. a circle, a rhombus or an arrow, its center point, tip or something similar is the selected pixel. In this case steer the digital-to-analog converter or the comparator a character generator that generates the symbol signals supplies. The position of the symbol on the screen is still determined by the contents of the line and position memory certainly.

If there is such a marking unit in a system with an analog display unit, which is used to select and If any image points are used for marking, then this unit can also be used to carry out the new method will. For better differentiation from other operating modes, it is advantageous for the acknowledgment process generates a special acknowledgment symbol that appears on the screen instead of the other symbols used. The light button signals for this are supplied by a character generator which, after pressing an Ouittierungstaste or a Switch is turned on.

To simplify operation, after pressing the acknowledgment button or switch, the mark can be moved when moving perpendicular to the line direction of the position counter from the pulses for the line counter set to a certain position, preferably the first or last character position will. If the mark is automatically brought to the first position in another operating mode, then it is expedient to represent it in the last character position when acknowledging.

Based on the drawing, in which an embodiment of an arrangement for carrying out the new method is shown is, the invention and further advantages and additions are described and explained in more detail below.

Four switches, Sx +, Sx-, Sy + and Sy- are used to move a mark displayed on the screen of a display device. In addition to the switches is symbolically represented by an arrow in which direction the brand if the internal switch is moved. For example, clock pulses should be present at the switches. When the switch Sx + is closed, these are sent to the input for counting up a position counter VRZx for the character position, which is an up / down counter. When closing the

Switch Sx- "is this counter VRZx of the clock pulses abwartlsgezah.lt. A second up / down counter can be used accordingly VRZy, which determines the line in which the ' Mark '/ is positioned., Can be counted up and down by closing the Sy + or Sy- switch. Is the counter VRZx fully counted, then it gives a carry pulse on the counter VRZy .. -

The optionally changeable contents of the position counters VRZx and VRZy are combined with the contents of a character counter Zx and a line counter Zy in a mark control MS compared. The character counter Zx is synchronized by a clock generator TG with the display of a line on the Screen of the display unit counted. Does he have his 'Counting capacity reached, which at the same time-the display of a line is finished, then he gives a carry pulse on the line counter Zy, so that this, if it was set to zero at the beginning of the display of an image, indicates the line that is currently being written on the screen. '"Are the contents of the position counter for the character parts VRZx and the character counter Zx as well as the contents of the position counter VRZy for the line and of the line counter Zy are the same, then the marker control MS sends a pulse to the gate circuits Tt and T2 away. A character generator ZM is connected to the gate circuit T1, which supplies pulses to represent a writing mark, is connected and a writing generator is connected to the gate circuit T2 ZQ, which generates a special acknowledgment symbol.

The gate circuits T1 and T2 are from a bistable Trigger stage BK controlled, which in turn by an Ouittierungstaste Q1 is switched. In the basic state of the bistable flip-flop BK, the gate T1 is released for the output pulses of the mark control MS and the gate, circuit T2 via the negation gate ■ N2 blocked. Further ' a gate G2b is blocked, the other input of which is the linked via a gate G2a according to an OR function

Pulses for moving the mark are fed perpendicular to the line direction. The output of the gate G2b is connected to the reset input of the position counter VRZx for the last character position. The impulses for Shifting the marks in the vertical direction are also fed to a gate G1a with an OR function, whose Output is connected to a gate circuit G-Ib. These is released in the basic state of the bistable flip-flop BK via a negation gate N1 and is at its output the reset input for the first digit of the counter VRZx is connected. This means that if the The cursor is moved in a vertical direction by closing one of the switches Sy + or Sy-, the counter VRZx

P is set to the first character position and the mark generated by the character generator ZM at the beginning of the line is pictured. If the bistable flip-flop BK is switched over by pressing the acknowledgment dial Q1, then gate T1 is blocked and gate T2 to the character generator for the acknowledgment character is released. It appears that is, the special acknowledgment symbol on the screen. At the same time the gate Gib is blocked and the gate G2b gives the impulses that when closing one of the switches 3y + or Sy- to move the mark in a vertical position Direction to the position counter VRZy for the line, to the reset input of the position counter

fc VRZx for the last character position, so that the acknowledgment character always appears at the end of the line.

If the quotation mark is placed in the line in which the message to be acknowledged is available, then the content of the position counter VRZy for the line is stored in a line register ZR of an output register AR accepted. By pressing an acknowledgment key Q2 + or Q2- the operator can enter their comments on the message in an acknowledgment register QR. In two weather registers Identifiers for the beginning and the end of a text are written into the SR and ER of the output register AR. To the

All the information about you can end anyway existing channel to be transmitted to the data processing system. Simultaneously with deir. Pressing one of the keys Q2 + or Q2- becomes the bistable multivibrator BK again reset and the normal cursor appears again on the screen. The acknowledgment signal can also be on another type can be written into the transmit register and transmitted. Instead of the acknowledgment button Q1 two buttons provided. If one is operated, then. a positive acknowledgment symbol and, when the other key is pressed, a negative acknowledgment symbol appears on the Screen shown. Instead of the buttons Q2 + and Q2-, only a single button is then necessary Press the acknowledgment symbol in the QR register and the transfer to the data processing / system started is. "Each of the two exit buttons Q1 controls a bistable multivibrator, which in the basic state is about an AND link to block gate G2b and the gate Give release. Each of the two receipt characters will generated in a character generator. If e.g. the acknowledgment key Q1 is pressed for the positive acknowledgment character, then the corresponding bistable multivibrator is switched over and the character generator for the positive acknowledgment character released, which is controlled in accordance with the character generator ZQ in the circuit according to FIG. When pressed the other acknowledgment key for the negative acknowledgment character the other bistable multivibrator is set and another gate circuit for the output pulses dei Mark control MS released so that the character generator is activated for the negative acknowledgment character.
