Figure 1 shows the structural and electrical circuit of the device; on. FIG. 2 is a block diagram of an optoelectro quantizing module; FIG. FIG. 3 shows a structural electrical switch circuit; Fig. 4 is a structural electrical circuit of a correction pulse former of a character. The device contains a voltage-to-time converter 1, element 2 OR, a driver of the correction and sign pulse 3, overflow analysis blocks 4 and 5, recorders 6-8, each recorder includes an optoelectronic quantizing module 9, drivers 10 and 11 pulses, switch 12, each recorder has inputs 13-17-, outputs 18 and 19 are equipped with five inputs, each optoelectronic quantizing module 9 has inputs 20-22 and optical outputs 23 and 24, each switch 12 has inputs 25-28 and outputs 29 and 30, each of the formers 10 and 11 has an optical input 31, an input 32 and an output 33, the driver 3 has inputs 34-37 and outputs 38 and 39, each recorder has control inputs 40 and 41, an input 42 of the measured voltage and a reset bus 43, outputs 44 and 45 overflows and an output of 46 digits of the result. The optoelectronic quantizing module (Fig. 2) contains quantrons 47, the number of which is equal to the base of the number system and NOT element 48, each quantron contains a transistor 49, an LED 50, photodetectors 5153, a diode 54; The switch (FIG. 3) contains And 55 and 56 elements. The correction and sign pulse former (FIG. 4) contains triggers 57-59, prohibition elements 60 and 61, OR 62 element and And 63 element. In converter 12, switch 12 (FIG. H) performs the function of time transfer, transfer and loan. When a high potential is simultaneously applied to the input 27 and a pulse (or a time interval to the input 25, the switch 12 outputs a pulse or a time interval to the output 29 and a potential to the output 30 when there is a low temperature on the input 28. On the contrary, while to input 28 and a pulse (or a time interval) to input 26, switch 12 outputs a pulse to output 30

or the time interval and the output 46 is low potential,

In an optoelectronic quantizing module (FIG. 2}, when a negative polarity reset pulse is applied to input 22, it is inverted by the HE element 48 and sets the first quantum to one state. At the same time, the reset pulse arrives at the reset inputs of the remaining quantrons and sets them to the zero non-illuminated state corresponding to the beginning of the module and indicating that the module does not contain information. Each quantron triggers an extremely fixed time T, which acts as a quantization step. Potential to input 21 and a pulse with duration t (or. time interval) to input 20, in the module one next quantron is triggered, after which the optical signal from its output enters the second input of the previously excited previous quantron, zeroes it. pulses or a time interval, the information represented by one excited quantron is shifted to the right, the value is determined by the position number I0, l, 2 ..., n of the excited quantron. After working on the last quantron, with the continuation of the signal applied to input 20, the first quantron is triggered, after which the last quantron is zeroed and the process of moving information to the right continues.

In the case of simultaneous supply of pulses (or a time interval) to input 21 and a low potential at input 27, the process of information movement in the module occurs in the opposite direction from right to left. After the first quantum plane is triggered, when the input signals are held, the last quantron is triggered, after which the first quantron is zeroed and the information shift process to the left continues from; ,

Shaper 3 is designed to determine the sign of the result, as well as adjust it when necessary. When a negative polarity pulse is applied to the input 34, it is inverted and sets the triggers 57-59 to the zero state. Therefore, there are no signals at outputs 38-39. When a pulse is applied to the input 35, the trigger 57, and hence the trigger 58, is set to one. The triggers 57 and 58 are intended respectively for storing the sign of the result of the cyclic impulse of the loan, in this case a signal appears on the driver of the generator 3, which means that the device contains information with a negative sign. After shaping,

negative sign, when the input measured input voltage stops, the zero potential is fed through the input 37 to the inverse input of the prohibition element 60. In this case, the OR 62 element outputs to the first output 38 of the imaging unit 3 a correction pulse or a cyclic loan pulse with a duration T. In the case of transfer of the transfer pulse from the senior registrar 8 to the input 36 when the sign state 57 triggers a single state, the trigger 59 is set to one state by a pulse fed from the output of the And 63 element. At the same time, this pulse arrives at the zero input of the trigger 57 sets it to the zero state. The presence of a single state of the trigger 59 means that a cyclic transfer occurs in the device. Therefore, after stopping the supply of the measured input signal, the zero potential through the input 37 of the generator 3 triggers a chain of elements 61 and 62. In this case, the OR element 62 outputs to the input 38 a correction pulse (cyclic transfer pulse) with duration X.

It is advisable to consider two cases of supplying input analog values - quantities with a positive sign and values with a negative sign.

At the initial time, a reset, negative polarity pulse is applied from the bus 43, which sets the device to the initial state.

/. . When feeding a measuring incremental

voltage (i.e., with a positive sign to the control input 40, a high potential is applied, to the control input 41. a low potential, and the measured voltage applied to the input 42 is converted over a time interval by means of a converter 1. The time interval the element OR 2 is fed to inputs 13 and 14 of recorder 6. In this case, the switch passes the time interval through output 29 to input 20 of the module, and low potential through output 30 to input 21 of the module. In this case, the information represented by the unit position code or in the form of ma ker, the module is moved from left to right. Once. quantron last state moved to excitation by further supplying timeslot reduction process occurs modulation logger 6 in the initial state, the first laser head zasvetits again.

At the same time, the optical signal from the module output 23 acts on the pulse shaper 10, which generates a transfer pulse with a duration t in the presence of a time interval at input 32. The generated pulse is transmitted through output 18 of this recorder to input 13 of the next recorder. The switch 12 of this recorder transmits a transfer pulse through an And 58 element (since a high potential has already been fed to the input), through output 29 to the input 20 of the module and leads to an increase in information in it by one, i.e. to triggering the next quantron and resetting the previously excited previous quantron. The process of triggering the next quantron and resetting the previously exciting previous quantron, i.e. the process of movement of information from the left to the right in the modules of all recorders occurs in a similar way and continues until the time interval is stopped. After the input voltage is discontinued in the form of a time interval, 13 and 14 of the first registeror entered, the quantrons will not be excited from each other, but the illuminated quantum dots will retain their state and record the result of the conversion by the unit direct position code. When applying the measured decreasing voltage / i.e. with a negative sign) a low potential is applied to the control input 40, a high potential is applied to the control input 41, and the measured voltage is converted into a time interval by means of transformers 1. The time interval through the OR 2 element is fed to the inputs 13 and 14 of the recorder 6 In this case, the switch 11 temporarily passes the interval through the output 30 to the input 21 of the module, and the low potential passes through the output 29 to the input 20 of the module. When a time interval arrives at the input of the 21st module, the information represented by a single-positional code or in the form of a marker is shifted to the right of the right. After the first quantron has switched to the excitation state, when the time interval is further applied, the last quantron is triggered, after which the first The quantron and information shifting process 1lt repeats. Simultaneously with the last quantron triggering process, when the first eiiie quantron is illuminated, the optical signal from the second output 24 kudul acts on the pulse shaper 11, which generates a loan pulse with a duration in the presence of a time interval at the input 32. The generated loan pulse is transmitted through output 19 of this recorder to the second input is the 14 next registrar The switch 17 of this recorder sends j a pulse of a loan through element I 56, since the input 28 already has a high potential), through output 30 to the input 21 of the module and leads to a decrease in the information in it by one, i.e. to triggering the previous quantron and zeroing the previously excited next quantron. The process of triggering the previous quantron and zeroing the previously excited next quantron, i.e. the process of moving information from right to left in the modules of all the recorders occurs in an anshotic manner and continues until the supply of the time interval stops, i.e. supply of measured voltage at device input 42. After the termination of the input voltage, the quantrons in all the modules cannot be excited from each other, but the locked quantrons retain their own state -. and. fix the result in the unit position reverse code. When the first loan pulse occurs in the last recorder 8, it from the output of the second driver 11 of the recorder 8 is fed to input 35 of the driver 3. In this case, a signal appears at its output 39 and at output 46, which means that the result in the converter is negative. After appearance. Negative-signal signal shaper 3 is in standby mode. When stopping the filing of the time interval to the inputs 13 and 14 of the recorder 6, the low potential from the output of the converter 1 is fed to the input 37 of the driver 3. In this case, the driver 3 generates a correction pulse with duration t ;, which through output 38 of the driver 3, through the element .OR 2 .. arrives at the recorder 6. Since the high potential at the control input 41 of the device, the correction pulse through the switch 12, through its output 30 enters the input 21 of the recorder module 6 and reduces the information in it by one. Thus, the process of adjusting the result with a negative sign. When a second loan pulse occurs in the last registrar 8, it is allocated through output 19 of the imaging unit 11, registrar 8 through block 5 to output 415 of the device and reports that an overflow has occurred in the converter in the negative direction. When a transfer pulse occurs in the forcing device 10 of the recorder 8, it enters through the output 33 of the fornirosh 10, through the output 18 of the registrar 8 to the input 36 of the driver 3.. If the previous analog value was negative, i.e. on the first pin 39 there was a signal, then after stopping the supply of the time interval and inputs 13 and 14 of the recorder b, the generator 3 will also generate a correction pulse with a duration f, which through the output 38 of the driver 3, through the OR 2 element enters the recorder 6. Since the control At the device input 40, a high potential of the correction pulse through the switch 12 through the output 29 enters the input 20 of the recorder module b and gfiodit to increase the information in VM per unit. Thus, the process of correction of the result With a positive sign. If a transfer pulse occurs in the imaging unit 10 of the recorder 8, it will be outputted via the output 33 of the generated pulses 10, through the output 18 of the registrar 8 through the unit 4, the AXOA 44 device and reports this. Completely positive. In a voltage-to-voltage converter, the number of quantrons in each optoelectronic quantizing module is equal to the base of the number system, the first quantron for representing zero, and the number of modules, i.e. the number of recorders depends on the required bits of the selected numbering system. The voltage converter in the code can be used in automation, measuring and computing devices. It is used as adders - successors of sequential action, where the input terms are specified in the form of time-pulse signals, and its rptoelectronic quantizing modules - as reversible shift registers, at the same time due to the use of quantrons in the design of these shear stimuli. than electronic shift registers. The converter is a universal operational converter that directly implements not only the conversion, but also the processing of output analog values with both positive and negative signs, regardless of their order of presentation, without a section of the computer.
