Kulakov P. Methods and tools for the parameters control of the cow's milk production technological process

The dissertation solved the problem of increasing the reliability of the control parameters of cow's milk production technological process. The object of research is the process of the technological process of cow's milk production parameters controlling. The aim of the study is to improve the reliability of the cow's milk production technological process measurement parameters control. The methods of probability theory, methods of the theory of measurement errors and processing the results of experimental studies, the methods of measuring control theory, methods of optimal linear filtering and data interpolation theory, are used. Quantification criteria of state, and quantification criteria of danger abnormal state of process constituents of cow's milk production, which based on the measurement results and parameters measurement control, are offered. An optical measuring method for operational control of the relative mass fraction of milk in a stream of water and milk solution is designed. A method of controlling the amount of time and animals using of carding plant is suggested. The methods of the milking machines working duration control, which based on experimental statistical characteristics of the milking processes duration is developed. Used optimum linear filtering of the object presence sensor output signal to improve the control method of animals passage on group milking installations. Developed the method of milk electrical conductivity measuring control by ensuring the uniformity of the electric field in the sensor electrode gap and accounting depending of the tolerance upper limit from the day of lactation. To improve the reliability of the milking parameters control, milk level sensor in the milk collection chamber of milking machine, which principle is based on the photoelectric area-voltage conversion is designed. The practical significance of the results is the introduction in the industrial production of new transducers, means of measurement control, algorithms and software, methods of measuring control duration of the milking machines and the constituent elements of automatic control systems of cow's milk technological process production parameters, so that the control accuracy of its parameters are increased. The results obtained in the dissertation are introduced at fifteen plants for the production of cow's milk or milking equipment, both in Ukraine and abroad. Theoretical and practical results can be used in the production of milking equipment, enterprises for the production of cow's milk, in the research organizations and in the educational process of higher educational institutions.
