UA73907A1 - Device for information record - Google Patents

Abstract

This invention relates to measuring equipment, and can be used in development of light scale devices, in systems of information regeneration on the speed information carrier, and also in apparatuses with mechanical indicators. The invention gives a possibility to simplify the device on the account of modification of the input data processing algorithm by way of increase of functional load on the code conversion units. This device has three code conversion units, the recording unit, generator, the EXCLUDING OR elements. Indicator of recorded information is performed in two steps. At the beginning the significant information grades are recorded, then the less significant ones. Due to conform generator frequency selection the input information record represents itself the range of lighting lines on the display unit matrix of indication elements.

Description

number M into an n-bit code combination of the form 00...010...0, containing a unit at the M--1-th position, and block Z - into a 1-bit code combination of the form 00...0... First from those combinations comes the first entry! of elements EXCLUSIVE OR 6, and the second - to the second input of element 6. The second input of the first element b receives a logical zero from generator 5. As a result, an n-bit code combination of the form 00...010... is formed at the outputs of element 6 0, containing a unit at the M--1-0th position.

Therefore, in measure B, enter! of block 4, a t-digit code combination of the form 00...011..1, containing M--1 units, is entered for the lower digits, and for the higher digits - a n-digit code combination of the form 00...010...0, containing unit on the 1st position. As a result, M full senior discharges of block 4 from tM elements are excited in beat A, and M-1st incomplete senior discharge from M--1 elements are excited in beat B.

The frequency of the pulses of the clock generator is vibrated in such a way that the information receiver perceives the output signal in the form of a continuous line from tiM-M'-1 excitation elements of block 4, which corresponds to the output of a number of the form tMM.

The device is implemented using K555 series microcircuits as the main element base and is designed to work with a data recorder on photo film, which is based on 128 LED elements that are part of four bodyless monolithic multi-element light-emitting lines. see Multi-element monolithic linear scale for recording information on photographic film O.R. Abdullaev. V.S. Abramov, L.S. Garba et al. Electron technology, Ser. 2. Semiconductor devices, 1980, vol. 8 (143) p. 54-58). Damn it! including 4x32 matrices. Operation of the device on the example of entering the number "37" (128 values are registered on the film: from "000" to "127"). The code "01 00111" is sent to the input of the device. The device works in two cycles. Clock A corresponds to the presence of a potential of logical units at the output of the clock generator 5 (see fig. 1), clock B - the presence of a potential of logical zero at the input of the generator. The operation of the device is described by the potential map shown in tables 1 and 2. They use the following designations: "-

B1 - the first block of code conversion;

B2 - the second block of code conversion; "

BZ - the third block of code conversion; chvzYY - even input of logical elements excluding OR; nVvZYY - odd inputs of logical elements exclusive OR; Cha

B4(c) - entrances of the senior levels of block 4;

Ba(m) entrances of lower levels of block 4; о вый - output elements exclusive OR. F

In clock A, one full discharge of 32 LEDs is excited, in clock B - the second incomplete senior discharge of six LEDs. At a clock generator frequency of 20kHz, a line consisting of 38 illuminated elementary sections is recorded on the moving film, which corresponds to the output of the number "Z7" (when a zero value is output, one elementary section is illuminated). When the input signal changes, the recorded line at each moment of time has a certain length, as a result of which a histogram is built on the film, reflecting changes in the input signal over time.
