Между сигналами от распознаваемых объектов .Between signals from recognizable objects.

Усиленные сигналы сравнивают между собой , например, в балансной схеме.Amplified signals are compared with each other, for example, in a balanced circuit.

Дл  получени  от корнеклубнеплодов 1 и почвы 2, например, сигналов разных знаков устанавливают такие коэффициенты усилени , чтобы при внесении в электромагнитное поле чувствительного элемента корнеклубнеплодов сигнал, характеризующий реактивное сопротивление К2Х, преобладал над сигналом, обусловленным активным KrR, а при внесении почвы - наоборот. По знаку выходного сигнала, полученного в результате сравнени  KiR и К2Х, определ ют вид распознаваемого объекта . Повышение точности распознавани  достигают те.м, что заданное соотношение между сигналами от растений и почвы получают независимо от добротности колебательных контуров , в которые включены чувствительные элементы, причем указанное соотношение устанавливают регулировкой коэффициента усилени  одного из усилителей в низкочастотной цеПИ , за счет чего упрощают настройку электронной схемы.To obtain from the root crops 1 and soil 2, for example, signals of different signs establish such gain factors that when introduced into the electromagnetic field of the sensitive element of the root crops, the signal characterizing the reactive resistance K2X dominates over the signal caused by active KrR, and when introducing the soil - vice versa. The sign of the output signal obtained by comparing KiR and K2X determines the type of object to be recognized. The increase in recognition accuracy is achieved by the fact that a given ratio between signals from plants and soil is obtained regardless of the quality factor of oscillatory circuits, which include sensitive elements, and this ratio is set by adjusting the gain of one of the amplifiers in a low-frequency circuit, thereby simplifying the configuration of electronic scheme.

Предложенный способ нримен ют в тех устройствах , чувствительные элементы которых обеспечивают большие потери высокочастотной энергии на излучение (антенны) или за счет загр знени  и расположени  над почвой.The proposed method is applied in those devices, the sensitive elements of which provide large losses of high-frequency energy due to radiation (antennas) or due to pollution and location above the ground.

Предмет изобретени Subject invention

Способ распознавани  растений от комков почвы и камней путем внесени  их в высокочастотное электромагнитное поле чувствительных элементов и замера изменени  комплексного сопротивлени , отличающийс  тем, что, с целью повышени  точности распознавани  и облегчени  настройки электронной схемы , активную и реактивную составл ющие комплексного сопротивлени , вносимого в высокочастотное электромагнитное поле чувствительных элементов, на последних измер ют отдельно , а нолученные сигналы усиливают и сравнивают между собой.A method for recognizing plants from soil lumps and stones by introducing them into the high-frequency electromagnetic field of sensing elements and measuring the change in the impedance, characterized in that, in order to improve the recognition accuracy and ease of setting up the electronic circuit, the active and reactive components of the impedance The electromagnetic field of the sensing elements is measured separately on the latter, and the received signals are amplified and compared with each other.
