SU1630712A1 - Device for measuring the rate and ratio of milker cycles - Google Patents

Abstract

The invention relates to agriculture and can be used to measure the frequency and ratio of strokes in the production, diagnosis and maintenance of milking machines. The aim of the invention is to improve the speed, accuracy of measurement and the expansion of functional capabilities of the device. The device contains a sensor 1 clock, D-flip-flop 2, vibration sensor 3, shaper 4 pulses, dividers 5, 9, 10 frequencies, switch b, control unit 7, generator 8 sync pulses, logic gate 11, period counters 12 and duration-duration 13 tact, registers 14, 15 of memory, digital-to-analog converters 16, 17, operational amplifier 18, source 19 of exemplary voltage, measuring instruments 20, 21. The device provides measurement of frequency and ratio of strokes (milking machine in each cycle of pulsations, averaging of measured values for five cycles of pulsations and the delivery of measurement results to analog gauges and an external recording device in the form of analog signals. 3 Fig. i (I
