Description

The invention relates to automation and computer technology and can be used in information reference and dispatching systems in the construction of automated design systems, operational control, software training, which operate in time-sharing mode during maintenance, a large number of screen consoles. Due to the fact that devices for displaying information are widely used in various information and computing complexes, the scope of application of the invention can be significantly expanded. A known multi-channel system for displaying information comprising a serially connected computing unit, a data link interface unit, a channel switch, operator consoles with typesetting and indicating devices based on a storage electron tube (CRT) with a visible image 1 In such systems, small the time of saving half-tone images by memorizing CRT limits the number of ecg remotes and increases the frequency of their access to computers. This is a significant disadvantage of multi-display systems based on halftone CRTs with a visible Image. Of the known devices for displaying information, the closest to the technical entity to the proposed is a device comprising screen consoles connected via serially connected input switch, data processing unit, image generator, output switch with corresponding storage tubes, priority block connected to processing unit data, output switch, screen consoles 2, In this device, the application of low-speed halftone memory CRT with a visible and image significantly increases the cost of computer time to build the image on their screens at each cycle an access to a computer. Moreover, the short image storage time on the dielectric of the target of such storage tubes does not allow obtaining high quality reproduced half-tone images. This is a significant disadvantage of the known device for displaying information. The purpose of the invention is to increase the speed of the device and display quality. This is achieved by inserting write-once blocks connected to the corresponding screen of remote controls, interrogator blocks connected to the imager, on-screen consoles, single-entry and storage tubes, and single-read blocks connected to the interrogator and through electron-beam storage tubes with appropriate on-screen consoles. The drawing is a block diagram of the device. It contains on-screen consoles 1, connected via a priority block 2 to a data processing unit 3, an input switch 4 connected to screen consoles and a data processing unit, an output switch 5 connected by an image formatter 6 and stored in CRT 7 with internal reading connected directly and through a single readout block 8 to the polled 9 polls. The screen consoles 1, connected directly and through the write-once units 10, are connected to a polling unit 9, which is connected to the image forming unit 6. The device for displaying information operates in the following way. The readiness signal of the screen consoles 1, made on the basis of half-tone CRTs with visible image, goes to priority block 2, From the output of block 2, the address code of the first control of the selected channel is transmitted to block 3 of data processing . According to the output code of the unit of priorities, the input switch 4 and the output KOMWiyat 5 are connected to the selected data channel. The control elephant enters block 3 and contains indications of the type of information (character or graphic), the direction of information exchange, the number of characters in the image page, the current address of the control word, the pointer to the second control word, its address, and the selected channel. Such addressing allows organizing a dynamic distribution of the memory of the data processing unit, as well as modifying the control words, deciphering the signs of the exchange direction and the type of information. The modified control words are inserted into the operational memory of the data processing unit 3. Control words enter the world of image b. Before plotting a new image on the dielectric of the target, a halftone storage tube with a visible image of the screen consoles 1 and on the dielectric of the target of a CRT memory with an electrical input and an electrical output (with internal reading) 7 from the imager 6 of the image, the polling channel 9 of the corresponding channel receives the command to erase the previously recorded images. The imaging unit 6 contains a character generator, an arc and vector generator, an interpolator and generates a voltage to control the recording beam of the CRT memory 7, as well as light pulses. In this case, an image in the form of a potential relief of various depths is formed on the dielectric of the target memory CRT with internal reading. After constructing the image of the target of one memory CRT 7, the output switch 5 connects another memory CRT and the process of image construction is repeated. The signal from the polling units 9 starts the single-reading blocks 8 and the single-write blocks 10, which synchronously unwind the readout CRT with internal read 7 and the write beam of a half-tone CRT with a visible image of the screen consoles 1 into the raster. during rewriting, amplitude-modulated video signals are extracted, which, during a single frame, arrive at the control electrode of the recording of half-tone memory handsets, on the screen of which These reproduce halftone graphic images corresponding to the topography of each of the storage CRTs with an electrical input and an electrical output. When the image is completely erased, the polling units 9 produce positive pulses, the repetition period of which is determined by the retention time. In some cases it is advisable to work in the gradual erase mode. Then the polling units produce a series of pulses with a change in duty cycle. This allows wide control of the erasure time. In this case, a separate splash on the screen of a halftone storage tube is merged for the operator's eye, forming a weak background that does not interfere with observation. After erasing the image in the memory of each of the screen console tubes, the image from the CRT memory with internal 7 is recorded again on the target of gray scale memories of the ELT 1, CRT memories with electrical input and electrical output allow to regenerate the recorded image at a frequency of 50 Hz for from two minutes for grapheks and up to 3–20 minutes for storing CRTs with LN-17 and LN-19 network controls, respectively. The number of readings (K) is determined by

For a graphekona type LN-104 K-BOOO, for LN-17 K-9000 and for LN-19 K-60000

Now, the playback time of information on the halftone storage tube screen (ig), when used as a buffer memory of a memory CRT with an electrical input and an electrical output, is determined

,

The playback time for the 31LN - LN-104 link is 33.3 hours, for the 31LN-1 link - LN-17 and for the 31LN-1 link - LN-19, respectively 50 and 330 hours and increases with i-g. At the same time, the number of consoles (N) / working with the data processing unit increases significantly and is determined by, -.

It should be noted that the total information reading time should not exceed the image storage time without reading, which is determined by the dielectric relaxation time. This time for internal readout CRTs is more than one month.

Thus, the use of internal readout CRTs as additional memory in display devices based on CRT memory with a visible image makes it possible to increase the playback time of the one-time half-tone image once a few thousand times, significantly reducing the imaging time and frequency of screen images. remote control units to the data processing unit, as well as use low-frequency units to control the recording beam of a CRT memory with an electrical input and electrically m exit. At the same time, a significant increase in information reproduction time allows an increase in the number of on-screen consoles connected and working together with the data processing unit. The use of a CRT memory link with an internal reading-potentialoscope with a visible image allows creating cheap, multifunctional multi-controller systems in which standard and unified units and blocks of television and computing equipment, to ensure the autonomy of each of the screen remotes, as well as Atit up to 30% of the cost of machine time for communication with a multi-platform system. In addition, screen consoles based on potentialoscopes with a visible image are informational and allow you to output complex half-tone images without drift, wobble and flicker. This significantly improves the quality of reproduced images.
