Изобретение относитс к вычислительной технике и может найти применение при исследовании и испытании машин и механизмов, преимущественно дл энергооцен1 и сельхозмгоиин и агрегатов, а тайже дл исследовани сложных приводов.: The invention relates to computing and can be used in the study and testing of machines and mechanisms, mainly for energy and agricultural plants and units, and taizhe for the study of complex drives .:

Известно устройство дл усреднени , .которое содержит преобразователь входного сигнала.в частоту импульсов, элементы И, реверсив-. ный счетчик 1,It is known a device for averaging, which contains a converter of the input signal. In the frequency of the pulses, the elements And, reversive-. Counter 1,

Недостаток устройства состоит в том, что существующий в преобразователе напр жение-частота интегрирующий конденсатор имеет температурный разброс емкости, что вносит температурные погрешности в результат .The drawback of the device is that the integrating capacitor existing in the voltage-frequency converter has a temperature variation of the capacitance, which introduces temperature errors in the result.

Известно также устройство, включающее тактовый генератор, подключенный к основному и дополнительном преобразовател м напр жени во временной интервал. На вход основного преобразовател подаетс исследуемы сигнал, вход дополнительного преобразовател закорочен, устройство .содержит также генератор счетных импульсов, элементы И и реверсивный счетчик 2,It is also known a device including a clock generator connected to the main and additional voltage converters in a time interval. The signal to be investigated is supplied to the input of the main converter, the input of the additional converter is shorted, the device also contains a counting pulse generator, AND elements and a reversible counter 2,

Благодар наличию дополнительного преобразовател и специгшьного метода включени его выхода достигаетс , температурна компенсаци устройства и снижение общей погрешности. В то же врем устройство не позвол ет усредн ть знакопеременный процесс .Due to the presence of an additional converter and a special method for switching on its output, temperature compensation of the device and reduction of the total error is achieved. At the same time, the device does not allow averaging of the alternating process.

Цель изобретени - расширение The purpose of the invention is the expansion

0 функциональных возможностей устройства путем усреднени знакопеременного сигнала.0 device functionality by averaging the alternating signal.

Указанна цель достигаетс тем, что в устройство, содержащее генератор счетных импульсов, выходThis goal is achieved by the fact that, in a device containing a counting pulse generator, the output

Claims

0 is the device input, an inverter and two elements are NOT, the outputs of which are connected to the third, respectively, the first and second elements AND, the element inputs are NOT connected respectively to the outputs of the second and first voltage converters in the time interval, and the inverter input is the device input and the output is connected to the information input of the second voltage converter in the time interval. The drawing shows a block diagram of the device for averaging. Input 1 of the device is connected to the first voltage converter 2 in the time interval, an inverter 3 analog signal, the output of which is connected to the input of the second voltage converter 4. The time interval, the clock generator 5 is connected to the trigger circuits of the converters 2 and 4. Output Converter 2 is connected to the input of the first element And 6 and through the element NOT 7 with the second element And 8, and the output of the converter 4 with the second element And 8 and through the element NOT 9 with the first element And b. The counting pulse generator 10 is connected to. other inputs of both elements And and 8. The outputs of elements And b and 8 are connected respectively with the inputs of the summation and subtraction of the reversing counter 11. The device works as follows. Clock generator 5 triggers converters 2 and 4, which, when the input signal 1 is positive, produce pulses, the duration of which is proportional to the signal amplitude and its zero value, respectively, because inverter 3 with its output negative potential short circuits the input of converter 4. Then the converter and generator pulses 10 arrive at the element I b, the output of which is in time equal to the difference between the duration of the impulse from the converter 3 and the inverted output signal of the transducer. bodies 4 at Vits burst. It arrives at the input of a summed-up reversible counter. At the same time, there are no pulses at the output of the element And 8 them. With the arrival of a negative signal, the input of converter 2 is short-circuited, and converter 4 produces a pulse, the duration of which is proportional to the value of the input signal. Further, the operation of the device is similar to that described with the difference that bursts of pulses appear at the output of the element AND 8 and the input subtraction of the reversible counter 11 arrives. At the output of elements b, there are no pulses. This device allows you to calculate the average values of alternating signals with high accuracy.
