Description

The invention relates to agriculture, in particular to systems for recording the amount of milk in the process of machine milking.

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

Figure 1 schematically shows a system for multichannel accounting of the amount of milk baked in the process of group milking; figure 2 - structure of the processing of the input signal; in Fig.3 - time diagrams of a multi-channel accounting system.

A system for multi-channel metering of the amount of milk baked in the process of group milking is installed on widely used vacuum milking machines. The count pulses received by the 1.1-1.p liter transmitter enter the electronic unit 2 via the communication line and enter the input shapers 3.1 - Z.p to restore the shape and amplitude. Then they go to meters 4.1 - 4.P of the pulse duration, where they are checked for truth (by duration and continuity), for the truth criterion for the impulse of the account about the passage of a kilogram portion of milk through the milk hose, 0.85 of the true time of milk withdrawal from the measuring device is taken . (During all this time, the impulse must be continuous). The presence of a margin in withdrawal time is associated with a change in the vacuum of the milking unit from a change in the mains voltage and the state of mechanics. Shorter impulses of noise, pickups and failures by duration meters are not skipped. For this purpose, the second inputs of the meters 4,14 .p of the duration of the input pulses receive pulses calibrated by the duration of the pulses from the control unit 5, in which they are generated from pulses of a higher frequency coming from the generator 6 pulses. The pulses passing through the meters 4.1 - 4.η of the duration of the input pulses arrive at the first inputs of the shapers 7.1 - 7.p pulse counts, where one short pulse is formed at the output of each long input pulse, and the pulses of all channels are sequentially distributed in time. This distribution is carried out by the control unit 5, from which the corresponding gates are supplied to the second inputs of the shapers 7.1 - 7.p count pulses. From the outputs of the formers, the counting pulses are fed to the first inputs of the switches 8.1 - 8.p, the second inputs of which receive pulses of accelerated counting from the control unit 5, from the control panel 9 to the third inputs of the switches 8.1 - 8.η, command 5 comes in the form of a potential signal (set by the operator) what pulses to send to the counters. In the operating mode, pulses from the shapers 7.1 - 7.η of the count pulses are passed, and in the test mode from the control unit 5. From the outputs of 10 switches 8.1-8. P count pulses are sent in parallel to 10.1 - 10.η liter operational counters, 11.1 - 11.η liter group counters and adder 12. Operational liter counters have a lower bit capacity of 15 and can be controlled via reset circuits with remote control 9 (which allows you to measure milk yield from several cows of equal productivity). The counters 11.1 - 11 .p liters are group and the adder 12 does not have such 20 possibilities, which ensures the objectivity of the account. The counters 10.1 - 10.η of pulses are operational, the counters 11.1 - 11.η are group pulses and the adder 12 at the moment of switching on the device receives a signal 25 of the initial setting from the initial state setting unit 13. Digital information from the counters 10.1 - 10 liters of operational counts goes to the indicators 14.1 14.η of operational counters, and from the counters 30 11.1 - 11, p liters of group counters to the indicators 15.1 - 15.η of group counters.

The pulses of the adder 12 count are fed to the liter counter of the adder 16 and the received digital information is sent to the 35 indication of the adder 17. Information about the amount of milk yield by groups (from group counters 11.1 - 11. l) and the total milk yield from the herd (from totalizer counters 16) is fed to the input of the information recording unit 18, one of the inputs of which, when the device is turned on, receives an initial state setting signal from the initial state setting unit 13 at 40.

The system operates as follows.

When you turn on the system is a one-time automatic installation of the initial state (Fig.Z) of all memory cells of the electronic unit 2 (from block 13 setting the initial state). During the flow of milk from dispensers 1.1 - 1. l of liters to the electronic unit 2, pulses of information about the number of kilogram portions of 55 kg of milk passed through the milking unit are received. On figa presents a plot of the signal of one of the sensors 1.1 - 1. liter liters entering the communication line, and on figv presents a plot of the signal after the communication line at the input of the input shaper 3.1-Z.p, where ___ is restored to shape at 5

1711736 6 coming signal. From the output of the input shaper 3.1 - Zp, the signal goes to the input of the meter 4.1 - 4.p of the duration of the input pulses, and the calibrated pulses of the reference frequency 5 (Fig. 3a) come from the control unit 5 to the second input. If the input signal is continuous and takes a certain number of reference pulses, then it is taken as an information signal, and a signal appears at the output of the meter 4.1 - 4, for a duration of 10 input pulses (Fig. 2c), and if the input signal is shorter (which is more likely under the influence of interference or failure), then on its trailing edge the meter circuit 4.1 - 4.p of the input pulses is zeroed and the output signal is not formed. The signal from the output of the meter is fed to the first input of the shaper 7.1 - 7, p count pulses, the second input of which receives a strobe from the control unit 5 (Fig. Sv 1). 20

The sequential distribution of counting pulses at the outputs of the shapers 7.1 - 7.p counting pulses is necessary for the possibility of performing the summation function. For this purpose, the other counters 7.2 - 7.p pulse counts gates come shifted in time (Fig. 3 b 2, b 3, b 4). The summation function is implemented by the adder 12, to which the count pulses 30 are received through the switch 8.1 - 8;

^! At the outputs of the shapers 7.1 - 7.η counting pulses for each input pulse, only one output counting pulse is generated, which are sent to the input of the switch 8.1 - 8.p, after which they arrive in parallel to the counters 10.1 - 10.η liters operational, counters 11.1 - 11.η liters group and the adder 12. To implement the function 40, check the counters 10.1 -, 10.p, 11.1 - Ts.p, 16 and block 18 recording information on the switch 8.1 - 8.p start unit 5 of the control pulses of accelerated counting, and 'from the control panel 9 is a potential signal 45 The second is supplied by the operator when certain controls are pressed. In the initial state, the counters receive only working pulses. The formation of the count pulses by the input pulses and their 50 summation by the adder block 12 is shown in FIG. 3 c, d, f, g, h. The count pulses from each switch go to the corresponding counters 10.1 - 10.η liters of operational, counters 11.1 - 11.η liters of 55 groups and through the adder 12 to the counters, liters of the adder 16. Operational liters counters are designed to control small milk yields ® groups of cows of the same productivity. For this purpose, they have control over the reset circuits from the control panel 9. Digital information of the counters 10.1 Yu.p liters of operational counters is displayed on the indicators of operational counters 14.1 14, p. The number of liters that each milkmaid needs to milk is calculated on the counters 11.1 11 .p group liters, and their total milk yield on the liter counters on the total 16. Digital information from the group liter counters is displayed on the group counters 15.1 - 15.p, and the totalizer information -on the indicator of the adder 17. To use the information on the group and total 15 milkings (for the purpose of its subsequent processing), it is entered into the information recording unit 18.
