Research results of the improved control unit of adaptive milking equipment

Abstract

Purpose. Increasing the efficiency of the process of machine milking of cows by improving the accuracy of determining the individual milk yield and the intensity of milk output of milking equipment based on a weight-type portion counter. Methods. Experimental studies were conducted on the basis of methods of planned experiment. The data obtained were processed using the methods of mathematical statistics and regression analysis. Results. The relationship between the weight of a portion of milk and the intensity of milk secretion from the interval between portions, which is measured by a weight-type portion counter, was experimentally established. According to the results of the researches, an advanced control unit for milking equipment on the Arduino element base was created, which adjusts the readings of a portion counter of weight type according to the actual intensity of milk production and provides adaptive change of the working vacuum pressure in the collector of the milking machine. Conclusions. An advanced control unit for milking machines has been developed, which allows to reduce the error of measuring milk yield from 12% to 7.3% to estimate the value of instant milk production with an accuracy of 5.7%.
