Description

The invention relates to an auto computer and computing technology and can be used to register digital information in a graphical form.

A digital code recorder is known which contains a register, a comparison circuit, a counter, a control device, a tape commutator, a mechanism, the latter being connected to the comparison circuit through a control device, a counter and a code switch, and a control device connected to the register through a register and comparison circuit. tape drive mechanism 1.

A disadvantage of the known device is the low recording density of informats1 | and per unit area of the recording medium, since for each scanning cycle only one value (k) of the bit code recorded in the register is recorded on the information carrier.

The closest to the technical essence of the invention is a device for recording information, containing n comparison circuits, connected to a register and a counter, a modulator of brightness, connected to comparison circuits and tape drives.

a mechanism which, through the control device, is connected to counter 2.

The disadvantage of this device is the limited scope due to insufficient recording density of digital information per unit area of the information carrier, since more than 10 parameters cannot be distinguished on the carrier.

The purpose of the invention is to expand the scope and increase the density of writing to the media.

This goal is achieved by the fact that in a device for recording information containing a register, the first input of which is the device input, the second input is connected to the first output of the control unit and to the first input of the counter, and the outputs to the first inputs of the corresponding group comparison elements, the second inputs of which are connected to the output of the counter, the second input of which is connected to the second output of the control unit, the third

25 whose output is the output of the device, and the inputs are connected to the first and second outputs of the recording unit, respectively, AND elements, signal interrupters, group triggers and the first OR element, the first input

which is connected to the output of the first group comparison element, the second input to the second input of the recording unit, the other inputs to the outputs of the corresponding AND elements, the first inputs of which are connected to the outputs of other comparison group elements, the second inputs to the outputs of the trigger group of the signal interrupters, respectively, the TpHrrepoia inputs the group and the signal breaker are connected to the second output of the recording unit, the input of which is connected to the output of the OR element, and also that the signal interrupter contains the second OR element, a trigger, a decoder and a second The meter whose input is the input of the circuit breaker, the output is connected to the input of the decoder, the first, second and third outputs of which are respectively connected to the first, second inputs of the trigger and the first input of the second OR element, the second input of which is connected to the output of the trigger, and output is the output of the signal chopper. FIG. 1 shows a diagram of the proposed device; in fig. 2 is a signal breaker circuit in FIG. 3 - examples of modified curves.

The circuit includes register 1, comparison elements of groups 2, 3, and 4, comparison element 5, element OR b, trigger 7 and 8, signal interpreters 9, counter 10, elements 11, 12 and 13, control unit 14, recording unit 15, the input and output of the recorder 16 and 17, the second counter 18, the decoder 19, another trigger 20, the second element OR 21.

The logger works in the following way.

In the recording unit 15 (B315), the abscissa axis scan (x-axis) is performed by discrete or continuous movement of the recording medium (for example electrothermal paper), and the vertical axis (Y-axis) is scanned, for example, by reciprocating a writing pin or with a knife and auger driven by a synchronous motor.

The control unit 14 (BU14} generates the commands necessary to control the registrator's electronic circuitry. The instruction from BUU14, sent via output 17 to external devices, serves as a request for issuing from the external device to the input 16 digital codes of numbers corresponding to the next values the ordinates of the recorded curves. At the command B315 about the end of the sweep along the y axis, the recording medium is shifted by one increment along the X axis, and the BU14 generates a pulse, setting the counter 10 to the zero state and rewriting digital codes

1st in register 1. The impulse from B315, corresponding to the beginning of the sweep along the axis Y, arrives at BU14, which from this moment begins to fill the strips with 10 counting pulses. The pulse of the beginning of the sweep along the Y axis also enters through the OR element b on the B315 and is recorded on the recording medium in the form of a zero reference mark. At the moments of equality of the code at the output of the counter 10 and the digital codes of the words stored in register 1, the elements of comparison 2-5 generate pulses that, directly or through triggers 7 and 8 and transducer 9, j bounce through eleventhe OR b B315, where recorded on the recording medium in the form of dots. Thus, during one scan cycle along the axis on the recording medium, a zero reference point and digital code numbers of ordinates n + 1 of the recorded curve are recorded as labels. The impulse from the output of the element 2 and the impulse of the beginning of the sweep along the Y axis are sent to the element OR b and then to the B315 directly, and not through the triggers or signal breakers.

Over m scanning cycles along the Y axis, an n + l curve will be recorded on the record carrier. Triggers and interrupters provide a clear distinction between recorded curves from each other due to labels along the Y axis. This makes it possible to increase the information recording density, because a large number of intersecting curves are recorded on the same area of the recording medium and it is easy to separate each of the recorded curves. from other curves.

Claims (2)

Depending on the type of curve modification selected, functional diagrams of the signal interrupters along the X axis are constructed. Thus, the first interrupter 7 of the signals along the X axis is designed as a trigger. The pulses of the beginning of the sweep along the Y axis, arriving from ЛПМ15, transfer trigger 7 and, after one clock cycle of the sweep along the Y axis, do not pass an OR 11 pulse through the Element 11, sent to it from the comparison element 3. pass - point (fig.Z curve 2), n-th marker 9 is made according to the scheme given in fig. 2. Counter 18 counts the pulses of the beginning of the sweep along the Y axis, arriving with B315. The decoder 19 selects the first pulse and triggers them to trigger 20. The pulse from the output of trigger 20 through the OR element 21 is fed to the nth element AND 13 and opens it, passing through the element OR 6 to B315 for A sweep time on the axis Y pulses, coming from the element of Comparison 5. These pulses are recorded on B315 as A points. Through A clock, the pulse from the second output of the decoder 19 resets the trigger 20, as a result of which the element And 13 closes and during the clock cycles along the axis Y does not let the pulses of the element 5 pass through. Through the A + B clock — from the third output of the decoder .19 to the element OR 21 receives a pulse, opening | b | ay element AND 13 on the C sweep steps along the Y axis, nticne of which the AND element 13 is again closed at a D such a sweep along the Y axis, which ends with an overflow pulse of the counter 18. Then the cycle repeats . The type of curve modification will be A points - B passes - C points - D passes - A points {FIG. 3, curve n).
