Description

The invention relates to devices for interacting a human operator with a computer, in particular, to input devices - information output performed using a display.

A device for editing information is known comprising a control unit and a symbol setting unit 1.

However, this device does not automatically allow acquaintance with the required symbol on the CRT screen.

It is also known a device for editing information, comprising a symbol setting unit, an AND group, a comparison circuit, a control unit and a video monitoring unit 2,

Such a device does not provide an automated withdrawal of a marker for acquaintance chosen by the operator with regard to one of the index symbols displayed on the screen, and requires significant time to produce the output of the marker.

The closest to the invention in its technical essence is a device for editing information containing a control unit, the first outlet of which is connected to

the first input of the first comparison circuit and the first inputs of the AND elements of the group, the second output to the input of the video control unit and the first input of the second comparison circuit, the first input to the output of the first comparison circuit, and the second input connected to the second input of the second comparison circuit and the first output of the block assigning characters, the second output of which is connected to the counting input of the counter, the setup inputs of which are connected to the outputs of the elements AND of the group, and the output connected to the second input of the first comparison circuit 33.

The drawback of the device is the presence of a storage unit for storing the Editing Program, which complicates the device. In addition, the device allows one to automatically search for the desired signal only if the desired symbol on the CRT screen is encountered only once. In most cases, the same symbols are encountered several times on different 3HjiKOMecTax CRT screens. Thus, for example, when editing computer work programs, the same commands, and, consequently, the same index symbols can be repeated several times in different | sections of the program. It takes considerable time to find each of them in the device.

The purpose of the invention is to simplify the device and increase speed.

The goal is achieved by the fact that the device for editing information contains the first trigger, the installation input of which is connected to the third output of the symbol specifying unit, the second trigger, the installation input of which is connected to the output of the first trigger, element III of which inputs are connected to the outputs of the second trigger and the second comparison circuit, and the output to the second input of the AND elements of the group and the reset inputs of the first and second triggers, and the NOT element, whose input is connected to the output of the first comparison circuit, and the output to the synchronous input second trigger.

The drawing shows a block diagram of the device.

The device contains a control block 1, a block 2 of character assignments, a chetcher 3, a first comparison circuit 4, a group of elements AND 5, a second comparison scheme b, an element 7, a video control unit 8, a first trigger 11, a second trigger 10 and an element.

The device works as follows.

The control unit 1 in a cyclical order makes reference to the tests of the screen of the video monitoring unit 8 for image regeneration, setting codes of familiarity numbers on the first output, and codes of corresponding televisions corresponding to the circulating numbers on the first output. At the same time, at the inputs of the first comparison circuit 4 there are a marker position code (from the output of the counter-3) and the current code of the familiarity number (from the first output of the control unit 1). At the moment of coincidence of these codes, a signal arriving at

first input of control unit 1. On this signal, block 1 generates an editing and display signal. marker sent from the second output (IT unit to video control unit 8. On this signal, video control unit 8 displays a marker on its screen, and the place of the marker corresponds to the code in counter 3; - the marker position counter. Keyboard marker movement key 2 generates increment signals which changes the code in counter 3 and changes the position of the marker on the video monitoring unit 8 accordingly. The alphanumeric keyboard of the unit 2 specifies characters when you press the keys ops at the first output signal of the corresponding character code and transmits it to the second input of the control unit l. At this signal i unit generates and transmits a block Videocontrol

8 signal to display the corresponding symbol in the place indicated by the marker. Thus, the editing (set) of information on the screen of the video monitoring unit 8 is carried out in the places sequentially designated by a marker. In addition to the editing operation, the device allows you to produce a sequence

search for a character found in several places on the screen of the video monitoring unit 8. At the same time, the second input of the second comparison circuit 6 comes from the alphanumeric keyboard of the block 2 task S1SHWOLS The character code corresponding to the key pressed, and the codes of the displayed characters from the second output of the control block 1. At the moments of coincidence of these codes, the second comparison circuit 6 generates a coincidence signal. After pressing the Search key, the search at the third output of block 2 results in a signal that goes to the setup input of the first trigger

9 and with its front edge sets it to one

five

(as a setup input, use, for example, the sync input of the .KI55TM2 element, whose information input is supplied with a constant unit potential 1 ial).

0 The signal from the output of this trigger goes to the setup input of the second trigger 10, the synchromesh input of which is inverted by the element NOT 11 is the comparison signal of the current code of the familiarity number and the marker position code from the output of the first comparison circuit 4. In this case, the second trigger 10 is set to one after the end of the comparison signal, since it only triggers on the positive edge of the input signal. Signal with. the output of the second trigger 10 is supplied to one of the inputs of the element AND 7, to the other input of which the signal of the comparison of the character codes from the output of the second comparison circuit is input. When these two signals coincide, I. 7 generates a match signal and transmits it to the second inputs.

0 elements AND 5 groups that transmit on this signal the familiarity number code from the first output of the shredding unit 1 to the installation inputs of counter 3, and is entered into it. But 5 measures familiarity of the desired character with

the output of the counter 3 is fed to the second input of the first circuit 4 and at the time of comparison with the circulating number the output of the circuit 4 is the signal that arrives at the first input of the block 1. As a result, the control unit 1 generates at the second output a signal for displaying a marker on the familiarity symbol, indicated by an index symbol, corresponding to the symbol selected on the alphanumeric keyboard of the character setting unit 2. Moreover, this familiarity is closest to the initial position (Marker. At the same time, the signal from the output of the AND 7 element goes to the INPUTS of resetting the First and Second flip-flops E and 10 and sets them to the zero state, then 7, the potential from the output of the second trigger 10 arrives at zero. Therefore, at subsequent matches of the codes of the search character located on other familiarities of the screen, element 7 does not signal B1, and the contents of counter 3 do not change. the one where the same search character is located, you need to press the Search key on the alphanumeric keypad of the character set block 2. At the same time, the triggers 9 and E are processed as described. In counter 3, the number of the next familiar character appears where the search character is located. , the marker is set at the next familiarity of the desired character.

The technical benefits of this device in comparison with the base object, for which the M7000 control computer is defined, are as follows. In the basic variant, the search and editing of symbols of the program of the technological process are implemented programmatically using the central processor and memory blocks for storing the editing program. In this device, this problem is solved by hardware.

means without the use of memory blocks.
