Title : Stabilization of suction pressure in the conceptual milking unit
Key words : milking machine; suction pressure;automatic regulation
Summary :

The objective of the paper was to verify the structure of the system for regulation and stabilization of absolute pressure, which supplies the autonomous milking unit. The described milking unit constitutes a modern technical solution which enables separation of suction pressure from the transporting one; moreover it enables measurement of the volumetric intensity of milk outflow from the cow udder quarter. The scope of the paper included: construction of the pneumatic supply system of the milking machine, development of the concept of control system, programming a PLC controller for the accepted control algorithm (basing on the previous scientific research of authors) and verification of the system operation on the laboratory stand. The main element of the control system is a microprocessor controller, where an algorithm of suction pressure control was implemented with the use of fuzzy logic; all calculations used for controlling this size are executed there. Results of the experimental research allowed a positive assessment of the described technical solution. The structure needs to be verified in milking conditions, however, research works emphasised positive effects with regard to stabilization of pressure supplied under a teat.
