Description

one

The invention relates to indicative indicator devices and can be used in radars and digital computers for outputting information to a screen of a cathode ray tube and for inputting information into digital computers for processing it.

A device for displaying information on a cathode ray tube screen contains column and row counters, row and column decoders, an address register with an address decoder, a symbol memory block, a control unit, a cathode ray tube, switches, character string registers 1.

However, the presence of switches in the known device does not allow to provide high speed information display.

It is also known a device for displaying information on the screen of a cathode ray tube, comprising its control unit associated with an input unit, a light pen pulse shaping unit, a backlight amplifier connected to a cathode ray modulator, a conjugation unit and a memory unit, connected to the character generator, the coordinate register and the interface unit, the deflection system of the cathode ray tube is connected to the amplifier unit associated with the digital-to-analog converter 2.

However, this device generates symbols and characters using standard generators, the connection of which controls an external digital computer by issuing a sign code and its coordinates on the screen of a cathode ray tube, which limits its scope only to highly specialized devices. and characters. In addition, in the known device for forming marks on the screen of the cathode ray tube, the microformat raster method is used, characterized in that, regardless of the configuration of the mark, the electron beam runs around the familiar place of the screen of the cathode ray tube

a figure, the so-called microraster, and only one sign is reproduced on it using the backlight, which limits the speed of its operation, determined by the time of polling of all cells of the microraster.

The aim of the invention is to improve the speed of the device for displaying information.

This is achieved by the fact that in a device for displaying information on the screen

The KoopAiiiiax adder is introduced into the cathode-ray tube; iodine: ispeedy to the register., ioditel, digital-analogue} transducer and sign generator, which is connected to the control unit on the amplifier of the signatte of the sign,; and the register of coordinates of points. The drawing shows a structural diagram of the proposed device. The device 1; the device for displaying information on the screen of a cathode ray tube contains a cathode ray tube 1, a unit for controlling 2, which is connected with an input unit o, a unit 4 forming nmul pulses of light iiepa o, an amplifier 6 of the sign of the sign office, a device n power unit 8. - Amplifier 6: the sign light is connected to the modulator of the electron-beam tube 1. The power block is 8 nodes. It is connected to the character generator 9, the coordinate register 10 and the sonr / rock block 7. The deviation of the young man's electron beam system 1 is connected to an amplifier unit 11 associated with digital A ro-analogue device is used by a transducer 12. A coordinate controller 13 is connected to the coordinate register 10, connected to a 12-pin analogue converter 12 n by a signal generator 9, which is connected to an equalization unit 6 of a sign illuminator. The character generator 9 contains a series-connected counter of 14 points of the sign's illumination, a control panel 15 and 16 coordinates of points, containing n bits. The interface device 7 via the inputs 17 is connected to the computer. A device for displaying information on the screen of a cathode ray tube works as follows. The input information format — the information array — from the computer to the inputs 17, and further, the interface block 7, bluntly into the block usi 8. Codes with the coordinates of the microraster are nonfixed from the corresponding zone of the block usm 8 to the coordinate register 10 and then are not affected The inputs of the adder are coordinates 13 and are used to select the location of the multi-format raster (necessary to form a given character) on the screen of the cathode-ray tube 1. Codes from the coordinates of the many coordinates of the points of illumination of characters and symbols are irrelevant from the corresponding memory unit area memory 8 to all n bits of the 16-point coordinate register. To the counting input of the detector there are 14 points of light illumination of the signal from the output of the control unit 2. Under the influence of these impulses, a counter of 14 points of light of the characters through the monitor 15 provides for the connection of the outputs of the register bits of the 16 coordinates of points to the second inputs of the coordinates of the coordinates of the coordinates of the 16 coordinates of the coordinates of the coordinates of the coder, 16 coordinates of the points, 16 form the coordinates of the points 1; the light of the formed sign in the given place on the screen of the electron-beam tube 1, which in the digital-analog converter 12 is built into the voltage (current), and then They are fed into the amplifier unit 11 and fed to the deflecting device of the cathode ray tube 1. Simultaneously with the formation of the coordinates of the points of the sign B for a given place on the screen of the cathode ray tube 1, the moduli of the sign lights from the output of the control unit 2 through time; 6 nodsvet zpaka. Thus, in the device for displaying information, only the codes of the coordinates of the nodes of the configuration of the configuration of the form or symbol are formed, and the remaining non-working points of the selected multi-format screen are not edited and the time on the unwrapped sections of the raster is not expended. The composition of the input information includes command codes, iio commands and output is included in the corresponding operating modes of control unit 2 (operating modes: editing, receiving or transmitting information, etc.) and form the necessary pulses to synchronize the operation of individual units of the device for displaying information. . In order to carry out an on-line information exchange between the digital computer, the input unit 3 with a keyboard is connected to the control unit 2 with a keyboard on the 4 shaped pulses unit with a light hole 5, which allow you to enter the necessary information into the electronic computer and output the information stored in it to us. correct the recalled information with the next one; 1. its in the computer for further processing. In the proposed device for displaying information, in addition to the well-known, the adder coordinate 13 is entered, the character generator 9 contains the register 16 point coordinates, the detector 15 n counts 14 points of the sign light, and also a number of new connections are entered into it, which is completely new. device operation speed for displaying information while simultaneously expanding its area of operation. This is due to the need to electronically beam the entire multi-format raster, regardless of the configuration of the sign or symbol being formed, since in the proposed device the electron beam travels around only the contour of the sign or symbol being formed, which leads to the new speed of the proposed device, since the time spent on the pas, p, respectively, on only the outline of the decorated sign or symbol, usually
