METHOD AND DEVICE TO CONTROL ANIMALS NUMBER AND LIVE WEIGHT IN HERD AND DETECTING WEAK AND SICK AMONG THEM

摘要

FIELD: agriculture.;SUBSTANCE: for accounting of healthy animals first time interval corresponds to onset of first animal on passage to farm. Signals of first and second time delay meet period of debilitated and sick animals admission. Animals are labelled with first and second colours, respectively. Turnstile opens at animal appears in passage for passing on weight platform. Turnstile is blocked till completion of weighing. Animal is weighed during its passage over platform. Weighing completed at exit of animal from platform. Device contains passage with side barriers, turnstile and sensor of animal presence, first and second actuators, two aerosol cylinders with paints, control and signalling unit. Electro-magnetic card based on bracelet is fixed on animal's leg. Turnstile comprises actuator and control unit for passage of animals one by one. In passage there are weight platform, converter with strain sensors, analogue-to-digital converter, comparator, inverter, control and data processing unit and information display unit. Animals are taken into account of number of turnstile openings.;EFFECT: higher production efficiency.;2 cl, 3 dwg
