На чертеже показана блок-схема устройства для цифрового измерения, запоминания и многократного воспроизведения дискретных значений однократного процесса .The drawing shows a block diagram of a device for digital measurement, storage and repeated playback of discrete values of a single process.

Устройство содержит аналого-цифровой преобразователь 1, первый блок 2 памяти объемом Ы , первый счетчик 3 адресов, второй блок 4 памяти объемом Ш , второй счетчик 5 адресов, блок 6 управления, синхронизатор 7, блок 8 определения границ сообщений, триггер 9, счетчик 10 объема сигнала, первый и второй счетчики 11 и 12 объема памяти, семь элементов И 13-19, мультиплексор 20, формирователь 21, индикатор 22. При этом клемма Вход соединена с аналого-цифровым преобразователем 1.The device comprises an analog-to-digital converter 1, a first memory unit 2 with a volume of Y, a first counter 3 of addresses, a second block 4 of memory with a volume of Ш, a second counter 5 of addresses, a control unit 6, a synchronizer 7, a block 8 for determining message boundaries, a trigger 9, a counter 10 the signal volume, the first and second counters 11 and 12 of the memory volume, the seven elements And 13-19, the multiplexer 20, the driver 21, the indicator 22. In this case, the input terminal is connected to the analog-to-digital Converter 1.

Устройство работает следующим образом.The device operates as follows.

По сигналу Пуск устанавливается исходное положение, при котором первый блок 2 памяти находится в режиме записи, а второй блок 4 памяти в режиме считывания. Через первый и второй элементы И 13 и 14 импульсы синхронизатора 7 поступают на входы первого и второго счетчиков адресов 3 и 5. Через седьмой элемент И 16 импульсы записи поступают на первый блок 2 памяти. Напряжение, поступающее на вход аналогоцифрового преобразователя 1 превращается. в цифровой код,который записывается в ячейки первого блока 2 памяти, а номер ячейки определяется положением первого счетчика 3 адресов. Очередной импульс синхронизатора 7, пройдя первый элемент И 13, изменяет состояние первого счетчика 3 адресов, что определяет запись одного цифрового кода в следующую ячейку первого блока 2 памяти. При записи всех щ ячеек первого блока 2 памяти, запись очередного ИИ+1 значения циф рового кода осуществляется снова в первую ячейку первого блока 2 памяти, Ш+2 значение цифрового кода записывается во вторую ячейку и т.д. При появлении на входе устройства электрического импульса на выходе аналого-цифрового преобразователя 1 появляется цифровой код, резко итличаюшийся по величине от цифрового кода предыдущих моментов времени, Блок определения границ 'сообщений 8 вырабатывает импульс, который переводит триг—The Start signal sets the initial position at which the first memory unit 2 is in recording mode and the second memory unit 4 is in read mode. Through the first and second elements And 13 and 14, the pulses of the synchronizer 7 are fed to the inputs of the first and second counters of addresses 3 and 5. Through the seventh element And 16, the write pulses are fed to the first memory unit 2. The voltage supplied to the input of the analog-to-digital Converter 1 is converted. in a digital code that is written into the cells of the first memory block 2, and the cell number is determined by the position of the first counter 3 addresses. The next impulse of the synchronizer 7, having passed the first element And 13, changes the state of the first counter 3 addresses, which determines the recording of one digital code in the next cell of the first memory block 2. When recording all the cells of the first memory block 2, the next AI + 1 value of the digital code is recorded again in the first cell of the first memory block 2, W + 2 the value of the digital code is recorded in the second cell, etc. When there is an electric pulse at the input of the analog-to-digital converter 1, a digital code appears, which differs sharply in value from the digital code of the previous time instants. The unit for determining the boundaries of messages 8 generates a pulse that translates trig

666790 rep 9 из нулевого состояния в единичное С этого момента времени счетчик 1Ό объема сигнала отсчитывает и следующих значений цифрового кода, которые также записываются в ячейки первого бло- 5 ка 2 памяти» При этом И - объем памяти, записанной предыстории. После того, как счетчик 10 объема сигнала насчитает hi- И импульсов, он устанавливается в нулевое состояние и одновременно формиро-’θ ватель 21 вырабатывает импульс, который устанавливает триггер 9 в нулевое состояние. По этому же импульсу блок 6 управления запрещает прохождение импульсов записи через седьмой элемент И 16 ^,5 на первый блок 2 памяти и подключает индикатор 22 к выходу первого блока 2 памяти через мультиплексор 20. Первый блок 2 памяти переходит в режим считывания записанной информации на индика- 20 тор 22. Пусть запись значений цифрового кода в первый блок 2 памяти закончилась на к ячейке. Тогда считывание информации начинается с к +1 ячейки, причем в ячейках οΉ+Ι по К+ И записана пред- 25 ыстория сигнала, а в ячейках ck+H+l по “к записан сам импульс. В режиме считывания информации с первого блока 2 памяти, блок управления 6 разрешает прохождение импульсов синхронизатора 7 че 30 рез пятый элемент И 17 на вход второго счетчика 12 объема памяти. Число состояний этого счетчика равно Ы . Поэтому в режиме считывания О состояние этого счетчика будет соответствовать к ячейке ₃₅первого блока 2 памяти.666790 rep 9 from zero to one. From this moment on, the 1Ό signal volume counter also reads the following values of the digital code, which are also recorded in the cells of the first memory block 5 ”. And, And is the amount of memory recorded in the history. After the counter 10 of the signal volume counts hi- And pulses, it is set to zero and at the same time the driver 21 generates a pulse that sets trigger 9 to zero. For the same pulse, the control unit 6 prohibits the passage of recording pulses through the seventh element And 16 ^{, 5} to the first memory unit 2 and connects the indicator 22 to the output of the first memory unit 2 through the multiplexer 20. The first memory unit 2 goes into the read mode of the recorded information on 20 torr 22. Let the recording of the digital code values in the first memory block 2 end on to the cell. Then the reading of the information begins with k + 1 cells, and in cells ο в + Ι along K + And the signal history is recorded, and in cells ck + H + l by “k the pulse itself is recorded. In the mode of reading information from the first memory unit 2, the control unit 6 allows the synchronizer pulses to pass 7 through 30 through the fifth element And 17 to the input of the second counter 12 of the memory volume. The number of states of this counter is equal to s. Therefore, in the reading mode O, the state of this counter will correspond to cell _{35 of the} first memory block 2.

По окончанию действия электрического импульса на входе аналого-цифрового преобразователя 1, блок 8 определения _4Qграниц сообщений вырабатывает импульс, поступающий на блок 6 управления. По этому импульсу блок 6 управления разрешает прохождение импульсов записи с синхронизатора 7 через шестой элемент И 15 на второй блок 4 памяти. Второй блок 4 памяти переходит в режим записи информации. Запись информации во второй блок 4 памяти происходит аналогично записи информации в первый блок 2 памяти.At the end of the action of the electric pulse at the input of the analog-to-digital Converter 1, the unit 8 for determining _4Q message boundaries generates a pulse arriving at the control unit 6. On this pulse, the control unit 6 allows the passage of the recording pulses from the synchronizer 7 through the sixth element And 15 to the second memory unit 4. The second block 4 of the memory goes into recording mode information. Information is recorded in the second memory unit 4 in the same way as information is recorded in the first memory unit 2.

Таким образом предлагаемое устройство позволяет записывать предысторию электрического импульса, а также импульс сразу после окончания предыдущего импульса, т.е. длительность одного цикла записи — воспроизведения составит для заявляемого устройства 2шЪ, в то время как для известного - (21и+и)ф .Thus, the proposed device allows you to record the background of the electric pulse, as well as the pulse immediately after the end of the previous pulse, i.e. the duration of one recording-playback cycle will be 2ш3 for the claimed device, while for a known one - (21 + +) f.

Сравнивая две длительности, можно отметить, что в данном устройстве разрешающая способность выше в . 2т раз.Comparing the two durations, it can be noted that in this device the resolution is higher than. 2t times.

At the same time, the Input terminal is connected to the analog-digital converter 1. The device operates as follows. On the Start signal, the initial position is established, in which the first memory block 2 is in the recording mode, and the second memory block 4 is in the read mode. Through the first and second elements And 13 and 14, the pulses of the synchronizer 7 are fed to the inputs of the first and second counters of addresses 3 and 5. Through the seventh element And 16, the write pulses are fed to the first memory block 2. The voltage applied to the input of the analogue converter 1 is converted into a digital code that is recorded in the cells of the first memory block 2, and the cell number is determined by the position of the first counter of the 3 addresses.
