The invention relates to agriculture, namely to devices for charging, maintenance and operation of milking machines.

The aim of the invention is to increase the functionality and increase the accuracy of the device.

FIG. 1 shows a block diagram of the ana, - lysator; in fig. 2 shows the voltage plots at the outputs of individual units, and the first pulses of the comparison circuit 12 are supplied with short pulses from the reference generator 11, which produces calibrated pulses. The number of calibrated pulses accumulated in the counter 15 is determined by the duration of the inverting pulsation of the pulsator from the inverter 6 supplied to the input of the comparison circuit 12.

On the second channel of the switch 10 of the OSUNO: Ui - at the output of the sensors of the pulsator, there is a monitoring of the duration of the vibrator and the vibratory pulsator, U2 - the trigger 1, the pulsation pulses. The controlled signal is fed to the input of the trigger 2 and through the switch 3 and the inverter 7 -

to one of the inputs of the comparison circuit 13.

OUSE - clock pulse generator, and - the first pulse generator on the leading edge. Us - pulse formaker on the falling edge, Ug - g N. The first input of the comparison circuit 13 supplies trigger 2, U the second comparison circuit, with the enable signal from the switch 10.

Calibrated pulses from the reference generator 11 are supplied to the second input of the comparison circuit 13. The information accumulated in the counter 16 is determined by the length 25

UB is the second pulse former on the leading edge, LJg is the third comparison circuit, Oy is the first comparison circuit. The pulse analyzer of milking machines contains two triggers 1 and 2, the output of a vibrating pulse. On which dyes are connected by a switch the second input of the counter comes a pulse with

the output of the former 8 for the initial zeroing of the counter 16.

The third channel of the switch 10 controls the number of vibrating pulses in one pulse of the pulsator. With the arrival at the comparison circuit 14 of the impulse impulse from the switch 10 and the vibrating impulses of the pulse-torus in the counter 17, rum 10 accumulates, and the output generator —JQ of these impulses. The fourth pulse pulsed 11 - with the inputs of the elements 12 and 13 of the processor, the switch 10 is set to

The outputs in “O” and on the indicators 18, 19, 20 are stored the recorded information. For further work with switch 3, all counts 3 are reset to the input of the first driver 4 pulses on the leading edge, the driver 5 pulses on the falling edge; the first inverter 6, the second inverter 7, the second shaper 8 pulses on the leading edge.

The outputs of the drivers are connected to the generator inputs 9 clock pulses. The output of the generator 9 is connected with switching devices that are also connected to the outputs of the switch 10 and inverters 6 and 7. The outputs of the comparison circuits 12, 13 and 14 are connected to the corresponding inputs of the counters 15, 16, and 17, and the pneumatic pulses 15, 16, 17 and restarting, the torus is connected to the output of the imaging unit 4. The second inputs of the counters 16 and 17 are connected to the output of the imaging unit 8, while the outputs of the counter elements 15, 16 and 17 are connected to the indicators 18, 19 and 20. In the Formula of

The pulse analyzer of the milking equipment of the signal sampling units of use is 40 rats, containing two sampling blocks, signals from the pulsator 21 and vibropulators, two triggers, clock generator

. pulses, three comparison circuits, the output of each of which is connected to the first input of the corresponding counter, and the outputs of the digits are connected to the inputs of the indicators, characterized in that, in order to increase the functionality and accuracy of control, it is equipped with a switch, two pulse formers on the leading edge, forcing pulses from triggers 1 and 2. Pulse clock pulses on the falling edge, two generator 9 performs automatic inverters, a switch and exemplary switching of the switch 10. pravleniegeneratorom, wherein the first and second blorabotoy generator 9 is effected sampling signal Vor ki formed as datmirovatel E 4 and 5 and the pulsator vyrabatyvayuschimichikov vibropulsatora sootvetkorotkie pulses for the front and rear governmental, output of which each edge of the pulses of the pulsator po-. The third channel is connected with the circuit of the switch 10 to the switch inputs, with 12 comparisons, to the second input of which at the first switch output is connected to the pulsatory investing pulse.
