Abstract

Методът и устройството намират приложение в животновъдството за диагностика на заболяването от мастит при млекодайните животни. С тях се повишава надеждността на диагностиката, намалява се времетраенето на изследването и се премахва субективният фактор. При метода се измерва импедансът на пробите мляко на два етапа, като се измерва протичащият през сонда ток и възникващото в нея напрежение и отношението на измерените величини се изчислява и запеметява. Същите операции се повтарят с взетите проби от четвъртинките на вимето, след което се образува отношение на импедансите на пробите с максималния импеданс. Това отношение се сравнява с гранична, предварително зададена стойност. Устройството се състои най-малко от една измервателна сонда и генератор на променливо напрежение, чийто изход е свързан с измервателни сонди, свързани с входовете на превключвател на измерваните точки, изходът на който е свързан с измервателен усилвател. Изходът на измервателния усилвател е свързан с аналогово-цифров преобразувател, свързан през управляващ възел с индикаторен възел. Превключвателят на измерваните точки е свързан с управляващия възел. 4 претенции, 6 фигуриThe method and device are used in animal husbandry for the diagnosis of mastitis disease in dairy animals. They increase the reliability of the diagnosis, reduce the duration of the examination and eliminate the subjective factor. In the method, the impedance of the milk samples is measured in two stages, by measuring the current flowing through the probe and the voltage arising in it, and the ratio of the measured values is calculated and stored. The same operations are repeated with the samples taken from the udder quarters, after which a ratio of the impedances of the samples to the maximum impedance is formed. This ratio is compared to a threshold, preset value. The device consists of at least one measuring probe and an alternating voltage generator, the output of which is connected to measuring probes connected to the inputs of a switch of the measured points, the output of which is connected to a measuring amplifier. The output of the measuring amplifier is connected to an analog-to-digital converter connected through a control node to an indicator node. The switch of the measured points is connected to the control node. 4 claims, 6 figures
