Description

Известные способы частотного телеизмерени  с использованием разделенных частотных каналов не могут обеспечить достаточно высокой точности измерени , так как погрешность измерени  в сильной мере зависит от нестабильности напр жени  и температуры.The known methods of frequency telemetry using split frequency channels cannot provide a sufficiently high measurement accuracy, since the measurement error depends to a great extent on voltage instability and temperature.

В предлагаемом способе этот недостаток устранен тем, что при передаче используетс  один генератор, дающий напр жение двух частот, распределенных во времени, из которых одна остаетс  посто нной, а втора  измен етс  в функциональной зависимости от измер емой величины .In the proposed method, this disadvantage is eliminated by the fact that the transmission uses one generator, which gives the voltage of two frequencies distributed in time, of which one remains constant and the second varies in functional dependence on the measured value.

На чертеже показана схема дл  осуществлени  описываемого способа измерени .The drawing shows a circuit for carrying out the described measuring method.

Генератор / дает напр жение двух частот, распределенных во времени . При условии, что конденсатор 2 общий дл  одного и другого контура , погрешность частоты биений определитс  только индуктивност ми 5 и - и практически не будет зависеть от генератора. Частота биений получаетс  в приемной части схемы путем подачи на смеситель 5 напр жени  непосредственно от генератора и через линию задержки 6, задерживающей сигнал на врем , равное длительности передачи первой частоты . Частота выделенных фильтром низкой частоты 7 колебаний измер етс  частотомером S.The generator / gives the voltage of two frequencies distributed in time. Provided that the capacitor 2 is common to one and the other circuit, the error in the frequency of the beats is determined only by inductances 5 and - and practically will not depend on the generator. The beat frequency is obtained in the receiving part of the circuit by applying voltage to the mixer 5 directly from the generator and through the delay line 6, which delays the signal by a time equal to the duration of the transmission of the first frequency. The frequency of the low frequency filter selected by the 7 vibrations is measured by the frequency meter S.

Предмет изобретени Subject invention

Способ частотного телеизмерени , отличающийс  тем, что, с целью уменьшени  погрешности измерени , возникающей от нестабильности напр жени  и температуры дл  передачи сообщений, примен ют две частоты, получаемые от одного двухчастотного генератора, одна частота которого посто нна, а втора  измен етс  в функциональной зависимости От измер емой величины, а частоту биений получают на лриемном конце путем подачи на смеситель напр жени  непосредственно от генератора и через линию задержки, задерживающей сигнал на врем , равнее длительности передачи первой частоты.A method of frequency telemetry, characterized in that, in order to reduce the measurement error arising from voltage instability and temperature for message transmission, two frequencies are used, derived from a single two-frequency generator, one frequency of which is constant From the measured value, and the beat frequency is obtained at the L-terminal end by applying voltage to the mixer directly from the generator and through a delay line delaying the signal for a time longer than STI transmission of the first frequency.
