Description

Изобретение отнооито  н оельойому хоз йству и предназначено дл  автоматизации разделывани  и уборки пропашных культур. в ооноЕЕОм авт.ов. л 471074 опвоан опособ распознавани  растений от комков почвы и камней путем Jнeceнн  их в высокочастотное электромагнитное поле чувствительных элементов раздел ного измерени  вызываемых при этом внесений активной и реактивной состав л юощх комплексного сопротивлени , усилени  и сравнени  между собой полученных сигналов. Однако точность распознавани  этим способом недостаточна  из-за вли ни  измен ющихс  свойств почвы. Цель изобретени  - снижение вли ни  измен ющихс  свойств почвы на точность распознавани  растений. J Этого достигают за счет того, что сигналы, соответствующие составл ющим комплексного сопротивлени , усиливают о коэффициентами преобразовани , установленными из услови  равенства этих сигналов при внесении в поле чувствительных элементов почвы. Согласно изобретению активную и реактивную составл юоще комплексного сопротивлени , вносимого распознаваемыми предметами в чувствительный элемент , замер ют рДельно. Например, воздействие активной составл ющей по изменению добротности, а реактизной - по изменению частотной расстройки резонансной системы, в которую включают чрствительный элемент. Сигналы, характеризующие вли ние указанных составл ющих, усиливают со своими коэффициентами преобразовани The invention is related to a domestic economy and is intended to automate the dressing and harvesting of tilled crops. in UNOEOM av.ov. l 471074 was recognized for recognizing plants from soil lumps and stones by executing them in the high-frequency electromagnetic field of sensitive elements of the divided measurement of the active and reactive contributions caused by the complex resistance, amplification and comparison of the received signals. However, the recognition accuracy by this method is not sufficient due to the influence of changing soil properties. The purpose of the invention is to reduce the influence of changing soil properties on the recognition accuracy of plants. J This is achieved due to the fact that the signals corresponding to the components of the complex resistance are amplified by the conversion factors established from the condition that these signals are equal when introduced into the field of sensitive soil elements. According to the invention, the active and reactive components of the impedance introduced by the recognizable objects into the sensitive element are measured individually. For example, the effect of the active component on the change in the quality factor, and the reactive one on the change in the frequency detuning of the resonant system, in which a stable element is included. Signals that characterize the effect of these components, with their conversion factors, amplify

а затем сравнивают мекду собой. Коэф-т фициенты преобразовайй  сигналов, соответствущих этим ооотавл ющши, устанавливают в зависимости от заданного соотношени  ме ду сигналами, обусловленными распознаваемыми предметами, подбира  их так, что сигналы, харантеризующ е составл ющие сопротивлени , вносимого одним из распознаваемых предметов, уравновещивают друг друга в схеме сравнени .and then compare mecdas with them. The coefficient of converting signals corresponding to these operators is set depending on a given ratio between the signals caused by recognizable objects, selecting them so that the signals that guarantee the resistance components introduced by one of the recognized objects balance each other in the circuit compare.

Например, дл  получени  режима пониженной чувствительности в почве, йоэффициенты преобразовани  сигналов, обусловленных активной и реа тивной составл ющими сопротивлени , вносимого почвой, устанавливают та , что эти сигналы уравновешивают друг друга, и на выходе схемы сравнени  отсутствует или резко ослабл етс  сигнал от поч1вы . При внесении растений сигналы, обусловленные одной из этих составл ющих сопротивлени , преобладают, что обеспечивает возникновение полезных сигналов на выходе схемы сравнени .For example, to obtain a reduced sensitivity in the soil, the conversion factors of the signals, due to the active and active components of the resistance introduced by the soil, establish that these signals balance each other, and the output from the comparison circuit is absent or the signal from the ground is sharply weakened. When plants are introduced, signals caused by one of these resistance components prevail, which ensures the appearance of useful signals at the output of the comparison circuit.
