Входы и выходы устройства и его элементов обозначены позициями 29-36.The synchronization unit (FIG. 3) contains a single vibrator 25, AND-NOT elements 26 and 27, a trigger 28. The inputs and outputs of the device and its elements are indicated by positions 29-36.

Устройство работает следующим образом»The device operates as follows "

Процесс записи информации в блоке 1 записи на носитель 19 сопровождается непрерывным перемещением последнего валиками 21 протяжки, которые вращаются под действием механизма 18. Последний состоит из электродвигателя, редуктора и блока управления электродвигателем.The process of recording information in the recording unit 1 on the carrier 19 is accompanied by a continuous movement of the latter by the pull rollers 21, which rotate under the action of the mechanism 18. The latter consists of an electric motor, gearbox and electric motor control unit.

Каждый раз, когда носитель 19 перемещается на величину, определяемую положением строки записи, датчик 13 положения вырабатывает импульс. В качестве датчика может быть, например, использован оптоэлектронный датчик, состоящий из диска с прорезями, осветителя и фотоприемника, Под действием движения носителя 19 валик 22 и диск с прорезями, которые находятся на одном валу, приводятся во вращение.Each time the medium 19 moves by an amount determined by the position of the recording line, the position sensor 13 generates a pulse. As a sensor, for example, an optoelectronic sensor can be used, consisting of a disk with slots, a illuminator and a photodetector. Under the action of the movement of the carrier 19, the roller 22 and the disk with slots that are on the same shaft are rotated.

Импульсы с выхода датчика 13 положения поступают на вход одновибратора 14. Длительность импульса 29 на выходе однобратора 14. Длительность импульса 29 на выходе одновибратора 14 определяется временем экспонирования изображения на носитель записи. Импульсы 29 с выхода одновибратора 14 поступают на базу ключа 15 и на базы ключей 24 блока 2 согласования. Ключ 15 открывается, одновременно открываются только те ключи 24, на эмиттерах которых имеется нулевой потенциал. Ключ 14 на время экспонирования подключает источник 16 питания к общему электроду 17 записи.The pulses from the output of the position sensor 13 are fed to the input of the one-shot 14. The duration of the pulse 29 at the output of the one-shot 14. The duration of the pulse 29 at the output of the one-shot 14 is determined by the exposure time of the image on the recording medium. The pulses 29 from the output of the one-shot 14 are supplied to the key base 15 and to the key bases 24 of the matching unit 2. The key 15 opens, at the same time only those keys 24 are opened, on the emitters of which there is a zero potential. The key 14 at the time of exposure connects the power source 16 to the common electrode 17 of the record.

Пусть сигнал 30 с инверсного выхода триггера 3 находится в единичном состоянии, а триггер 28 узла 5 синхронизации подает разрешающий потенциал на вход схемы 26 И-НЕ. ЭВМ (не показана) последовательно подает че30 рез мультиплексор 6 коды очередных точек кривых на адресные входы блоков 7 и 8, и одновременно посыпает сопровождающий сигнал 31 на вход одновибратора 25 синхронизатора 5. Сигнал с выхода одновибратора 25 через элемент И-НЕ 26 подается на управляющий вход блока 7, ив ячейках блока 7 по адресу, соответствующем кодам очередных точек кривых, запоминается 40 1. единица.Let the signal 30 from the inverse output of trigger 3 be in a single state, and the trigger 28 of the synchronization unit 5 supplies a resolving potential to the input of the AND-NOT circuit 26. A computer (not shown) sequentially supplies, through multiplexer 6, codes of the next curve points to the address inputs of blocks 7 and 8, and at the same time sprinkles the accompanying signal 31 to the input of the one-shot 25 of the synchronizer 5. The signal from the output of one-shot 25 through the AND-NOT 26 element is fed to the control input of block 7, and in the cells of block 7 at the address corresponding to the codes of the next points of the curves, 40 1. unit is stored.

Сигнал 32 на прямом выходе триггера 3 под действием заднего фронта импульса сигнала 29 устанавливается в единичное состояние. Под действием 45 того же импульса 29 триггер 28 синхронизатора подает разрешающий потенциал на вход элемента И-НЕ 27. Под действием сигнала 32 импульсы 33 с генератора 10 через элемент И. 9 по50 даются на счетный вход счетчика 11, на одновибратор 25 синхронизатора. Управляющий сигнал с выхода одновибратора 25 через элемент И-НЕ 27 поступает на вход У2 блока памяти 8.The signal 32 at the direct output of the trigger 3 under the influence of the trailing edge of the pulse signal 29 is set to a single state. Under the action of 45 of the same pulse 29, the trigger of the synchronizer 28 supplies the resolving potential to the input of the AND-NOT element 27. Under the action of the signal 32, the pulses 33 from the generator 10 through the element I. 9 to 50 are given to the counting input of the counter 11, to the synchronizer 25 single-vibrator. The control signal from the output of the one-shot 25 through the element AND-NOT 27 is fed to the input U2 of the memory unit 8.

Причем низкий уровень сигнала на входах У1 и У2 соответствует режиму чтения из блока, а высокий уровень записи в блок памяти.Moreover, a low signal level at inputs U1 and U2 corresponds to the reading mode from the block, and a high level of writing to the memory block.

После заполнения счетчика 11 числом импульсов, равным количеству электродов токоподвода 20 блока записи, счетчик сбрасывается, а на выводе переноса вырабатывается импульс 5 34, который в свою очередь сбрасывает триггер 3 и сообщает ЭВМ о готовности устройства к приему очередной информации.After filling the counter 11 with the number of pulses equal to the number of electrodes of the current supply 20 of the recording unit, the counter is reset, and a pulse 5 34 is generated at the transfer terminal, which in turn resets trigger 3 and informs the computer that the device is ready to receive the next information.

В процессе изменения значений на 10 информационном выходе счетчика 11 в моменты, когда его значение совпадает с адресом ячейки, по которому в блоках 7 и 8 хранится 1 на выходе блока памяти появляется импульс,!5 который определяет положение точки кривой на строке записи.In the process of changing the values at 10, the information output of counter 11 at the moments when its value coincides with the address of the cell at which 1 is stored in blocks 7 and 8 at the output of the memory block, an impulse appears! 5 which determines the position of the curve point on the recording line.

К моменту окончания работы счетчика все ячейки блока 8, где хранились позиционные коды, предыдущих 20 значений кривой, очищаются, так как на его входе сигнал 30 обнулен.By the time the counter is finished, all the cells of block 8, where the position codes were stored, of the previous 20 values of the curve, are cleared, since at its input signal 30 is reset.

Импульсы 35 с выходов блока памяти через элемент ИЛИ 12 поступают на счетный вход триггера 4, на вы- 25 ходе которого формируются сигналы 36, где длительность участка с низким потенциалом пропорциональна разности амплитудных значений, принадлежащих смежным временным интервалам 30 квантования точек дискретизации кривой. Сигнал с выхода триггера 4 поступает в регистр сдвига блока согласования, где под действием импульсов 33 с выхода элемента И он разворачивается в строку записи.Pulses 35 from the outputs of the memory unit through the OR element 12 are fed to the counting input of trigger 4, at the output of which signals 36 are generated, where the duration of the low-potential section is proportional to the difference in amplitude values belonging to adjacent quantization time intervals 30 of the curve sampling points. The signal from the output of trigger 4 enters the shift register of the matching unit, where under the influence of pulses 33 from the output of the element And it is expanded into a recording line.

Под действием очередного импульса 29 блока записи триггер 4 устанавливается периодически в исходное состояние, а информация с регистра сдви~₄₀га блрка согласования записывается на.норитель. При этом на носитель 3 записываются все значения, соответствующие числам между двумя точками дискретизации кривой, принадлежащими соседним временным интервалам квантования, т.е. смежные точки оказываются соединенными непрерывной линией.Under the action of the next pulse 29 of the recording unit, trigger 4 is set periodically to its initial state, and information from the shift register ~ ₄₀ ha of the matching block is recorded on the target. In this case, all values corresponding to the numbers between two curve sampling points belonging to adjacent quantization time intervals are recorded on the carrier 3, i.e. adjacent points are connected by a continuous line.

После окончания импульса 29 процесс преобразования повторяется, с той лишь разницей, что перед началом преобразования в блоке 8 хранятся позиционные коды очередных точек кри-вых, а в блок 7 - предыдущих точек $$ кривых.After the end of pulse 29, the conversion process is repeated, with the only difference being that, before starting the conversion, in block 8, position codes of the next points of theout, and in block 7 - the previous points of $$ curves.

Устройство существенно отличается от известных. В известных устройствах записывается только значение, соответствующее дискретизации кривой. При больших скоростях изменения сигнала, особенно при записи непериодических процессов, например при записи данных промыслово-геофизических исследований скважин, расстояние между точками оказывается достаточно большим. Кривые записи при этом практически не поддаются расшифровке.The device is significantly different from the known ones. In known devices, only the value corresponding to the discretization of the curve is recorded. At high rates of signal change, especially when recording non-periodic processes, for example, when recording data from field-geophysical studies of wells, the distance between the points is quite large. Curved recordings are practically undecipherable.

Устройство позволяет соединять точки дискретизации кривой непрерывной линией, что значительно облегчает расшифровку и интерпретацию кривых непериодических процессов, в том числе и данных промыслово-геофизиче’ских исследований скважин.The device allows you to connect the sampling points of the curve by a continuous line, which greatly facilitates the interpretation and interpretation of the curves of non-periodic processes, including data from field-geophysical surveys of wells.

The inputs and moves you device and its elements train nacheny numerals 29-36. The device operates as follows. The process of recording information in the recording unit 1 on the carrier 19 accompanies with the continuous movement of the latter by rollers 21 of the pulling, which rotate under the action of mechanism 18. The latter consists of an electric motor, a gearbox and a motor control unit. Each time the carrier 19 is moved by an amount determined by the position of the recording line, the position sensor 13 generates a pulse. For example, as a sensor. an optoelectronic sensor consisting of a slotted disk, an illuminator and a photodetector is used. Under the action of the movement of the carrier 19, the roller 22 and the slotted disk, which are located on the same shaft, are rotated. The pulses from the output of the position sensor 13 are fed to the input of the single vibrator 14. The pulse duration 29 at the output of the single-coupler 14. The pulse duration 29 at the output of the single vibrator 14 is determined by the exposure time of the image on the recording medium.

The key 15 is opened; at the same time, only those keys 24 are opened, on whose emitters there is zero potential. The key 14 for the exposure time connects the power supply 16 to the common recording electrode 17. Let the signal 30 from the inverse output of the trigger 3 be in the unit state, and the trigger 28 of the synchronization node 5 supply the enabling potential to the input of the AND-NOT circuit 26. A computer (not shown) sequentially sends, through multiplexer 6, codes of successive points of the curves to the address inputs of blocks 7 and 8, and simultaneously sprinkles the accompanying signal 31 to the input of the synchronizer one-shot 25: 5. The signal from the output of the one-shot 25 through the AND-HE element 26 is fed to the control input of block 7, and the cells of block 7 at the address corresponding to the codes of successive points of the curves are stored in 1. unit. Signal 32 at the direct output of flip-flop 3 under the action of the trailing edge of the pulse of signal 29 is set to one. Under the action of the same pulse 29, the synchronizer trigger 28 supplies the resolving potential to the input of the element NE-NE 27. Under the action of the signal 32, the pulses 33 from the generator 10 through the element I. 9 are fed to the counting input of the counter 11, to the synchronizer one-shot 25. The control signal from the output of the one-shot 25 through the IS-NOT element 27 is fed to the input U2 of the memory block 8. Moreover, the low level of the signal at the inputs U1 and U2 corresponds to the reading mode from the block, and the high level to the memory block. 3 After the counter 11 is filled with the number of pulses equal to the number of electrodes of the current lead 20 of the recording unit, the counter is reset, and a 34 pulse is generated at the transfer output, which in turn resets the trigger 3 and informs the computer that the device is ready to receive the next information. In the process of changing the values on the information output of the counter 11 at the moments when its value coincides with the address of the cell, in which block 7 stores 1, the output of the memory unit generates an impulse that determines the position of the curve point on the recording line. By the time the counter ends, all the cells of the block 8, where the position codes were stored, of the previous curve values, are cleared, since at its input the signal 30 is zero. The pulses 35 from the outputs of the memory unit through the OR element 12 are fed to the counting input of the trigger 4, the output of which signals 36 are formed, where the length of the low potential section is proportional to the difference in amplitude values belonging to the adjacent sampling points of the curve. The signal from the output of trigger 4 enters the shift register of the matching unit, where, under the action of pulses 33, from the output of the element I, it turns into a zacis line. Under the action of the next pulse 29 of the recording unit, the trigger 4 is periodically reset to the initial state, and the information from the shift register of the matching register is written to the prioritizer. In this case, all values corresponding to the trunks between the two sampling points of the curve belonging to the adjacent quantization time intervals, i.e. adjacent points are connected by a continuous line. After the end of the pulse 29, the conversion process is repeated, with the only difference that before starting the conversion, in block 8, the position codes of the next curve points are stored, and in block 7, the preceding curve points are stored. The device is significantly different from the known ones. In the known device 124, only the value corresponding to the curve discretization is recorded. At high signal change rates, especially when recording non-periodic processes, for example, when recording geophysical well survey data, the distance between the points is quite large. At the same time, the recording curves are practically unrecognizable. The device allows you to connect the sampling points with a curve of a continuous line, which greatly facilitates the interpretation and interpretation of non-periodic processes, including well log data.
