Definitions
- the subject of the present invention relates to a method for milking an animal, in particular a cow.
- the udder tissue between the glandular and teat cistern contracts increasingly under the influence of the milking pressure. Due to the increased vacuum inside the teat cup liner of a milking cup and the drying milk flow towards the end of the milking process, a fluid accumulation in the area of the Mariestenberg vein ring can be caused. This fluid buildup can lead to edema, which usually leads to permanent occlusion of the milk-conducting channels the teats can come, which can only be opened again by a higher pulling force downwards. This effect is exacerbated by the acceleration pressure and flow pressure of the milk column. As a rule, this leads to the fact that the milking cup starts to climb up on the teat and that the milking out or post-milking phase is initiated at an early stage and the milking process is ended faster than desired.
- EP0534565B1 is a method of automatically milking animals, such as cows, in a device having "a milking plant, comprising a computer and a milking robot with Zitzenbechem applied to the teats of an are automatically connect animal to be milked is known. From a Flow sensors generate signals that indicate the start and end of milk flow from at least one teat, and if the computer determines that the dead time between the time, a sensor that responds to a vacuum also has a sufficient vacuum in an associated one If the teat is connected to the teat cup and the time has passed, and the flow meter detects the onset of a milk flow from this teat beyond a predetermined point in time, the teat cup is automatically put out of operation.
- DE2844562B1 discloses a further method for independent measurement in the case of mechanical milk withdrawal. For this, a continuous milk flow measurement is carried out. The measurement records the changes in milk flow per unit of time. Immediately after a decrease in the milk flow of more than 1 kg per minute, which has been detected for a period of 5 to 10 seconds, a low milk flow is detected, so an additional signal can be generated, which causes a decrease in the milking cluster.
- the present invention is based on the objective of specifying a method for milking an animal, in which the end of the milking process is determined such that, on the one hand, the teats of an animal to be milked are spared and, on the other hand, a relatively complete milking out can be ensured.
- a parameter of the milking process is first determined.
- This parameter is composed of at least one of the following variables: the actual value of the milk flow, its change over time and Depending on the at least one parameter, a threshold value for determining the end of a milking process is determined.
- This end of the milking process is predicted on the basis of the parameter and the threshold value at least one evaluation variable takes into account at least one of the following variables: the actual value of the milk flow, its change over time and / or the accumulated milk quantity
- the end of the milking process is initiated when the evaluation variable essentially corresponds to the threshold value, or therefor ter sinks.
- This method according to the invention avoids the risk of a very incomplete udder emptying and, on the other hand, the risk of blind milking and the hyperkeratosis caused thereby.
- This method according to the invention makes use of the knowledge that the milk flow curve has a typical course, so that depending on the milk flow at the start of a milking process, it can be predicted with a high probability after which time the end of a milking process should be initiated. With this measure, it is not absolutely necessary to determine the milk flow permanently with high resolution during the entire milking process. Instead, an adaptation to the course of the milk quantity in the milking process can take place, for example, on the basis of the improved filtering via the characteristic variable or evaluation variable.
- the sampling rate can also be adjusted so that the amount of data and thus the load on the controller can be reduced to a minimum.
- MF indicates the milk flow
- MM is the expected amount of milk e.g. the total milk expected.
- the expected amount of milk or the total milk to be expected can be determined using several milking processes.
- K1, K4 are proportional factors and K2 and K5 are time constants which advantageously allow an evaluation of the various dynamic aspects when parameterizing the method.
- the parameter KG can be determined in the same way as the company variable BG, since both the parameter KG and the company variable BG are composed of at least one of the following variables: the actual value of the milk flow, its change over time and / or the accumulated milk quantity. However, this is not absolutely necessary.
- the characteristic variable at time t (KG t ) is preferably determined in the same way as the evaluation variable.
- the threshold value be determined from the evaluation variable and the characteristic variables at the time of the threshold value in such a way that a larger evaluation variable / characteristic variable also results in an increased threshold value.
- the evaluation variable / characteristic variable and the threshold value are linked to one another by a calculation rule in which all variables are used as comparable in the process.
- the comparison between the evaluation variable and the threshold value can in particular be carried out in such a way that when the acceptance signal is triggered with a larger evaluation variable, the threshold value is also set larger.
- the threshold value it is proposed, for example, that it be determined in accordance with the relationship.
- K4 corresponds to an offset of the evaluation variable
- K5 and K6 are dimensionless variables.
- one or more parameters KG P can also be used in a similar manner in the determination of the threshold value if these are calculated separately for different phases of the milking process.
- a target value which defines the start of a milking process is determined.
- a period of time between the start of the milking process, which is determined by reaching "the setpoint is correct, and a point in time at which the threshold value for ending the milking process is determined is predetermined.
- the evaluation variable essentially corresponds to the target value.
- the time period between the start of milking and the time at which the characteristic variable is determined is preferably less than two minutes. A procedure is preferred in which this time period is essentially one minute. After this period it has been found that e.g. There is a defined milk flow that forms the basis for a predicted end of the milking process. Other or additional criteria, in particular the change in the milk flow over time and / or the accumulated milk quantity and / or the milk quantity to be expected, can also be used for determining a milking end.
- the time (to) is reached when the parameter essentially corresponds to the target value (S).
- this parameter initially represents the milk flow and this reaches the target value of at least 50 g / min, preferably 75 g min, in particular 100 g / min.
- the minimum milk flow of a target value is greater than 50 g / min, preferably greater than 150 g / min, in particular 200 g / min.
- the actual milking process preferably begins when the target value is reached.
- the point in time can be defined by a time period after an attachment process.
- the end of the milking process is preferably defined by at least one threshold.
- the fact is used that the target value can also be compared directly with the evaluation variable / parameter.
- the setpoint can therefore also be understood as if it had been obtained from the milk flow using the above formula.
- the individual character of the above formula for each milking process enables the target value to be determined for each animal, which can then be provided before each milking process.
- the time (t 0 ) can thus be determined by comparing the setpoint with the parameter.
- the point in time (t 0 ) is predetermined and the calculation of the parameter KG (t 0 ) is fixed in time.
- the specification depends on the phase of the milking process.
- parameters be determined at the end of an add-on process, after the withdrawal of the cistern milk, towards the end of the stimulation, or after a threshold for the minimum milk flow has been exceeded or after the end of the main milking phase. This leads to phase-specific parameters (KG P ), which can also be included in the calculation of the threshold value.
- the milking process be at least "divided into two phases.
- the phases can be, for example, the phase in which cistern milk is removed, the milking start, a main milking time and an end A parameter and an associated threshold value are determined for each of these milking phases.
- the number and duration of the phases can be freely selected. It is advantageous if the division of the milking process into individual phases is based on the characteristic course of the milking flow based on the time, so that characteristic variables - phase parameters, phase evaluation parameters, phase threshold values - are also determined for the course of the milking process, which provide relevant information about the milking process.
- a threshold value for determining the end of the milking process is determined from the phase parameters, the phase threshold values and / or from the phase evaluation variables. Since the duration of the individual phases represents further information, in a further preferred embodiment, these can be included in the calculation of the threshold values for the end of a phase and in particular for the calculation of the threshold during the decrease.
- the threshold value in the first phase is predetermined from the target value and, according to the preceding considerations, results from settings or animal-specific parameters that are provided at the beginning of a milking process.
- phase threshold value essentially corresponds to or drops below the associated phase parameter and, if appropriate, a phase-dependent time offset has elapsed. It is not absolutely necessary that such a time offset when determining the phase valuation variables is taken into account.
- a threshold value for determining the end of the milking process is formed from the evaluation variables at the end of the milking phases and / or from the times of the phases of the milking process.
- the evaluation variable is preferably determined continuously, so that the end of the milking process is initiated when the associated evaluation variable essentially corresponds to the threshold value or falls below it.
- the milk flow and MMp indicate the amount of milk to be expected for the individual phases.
- Kl, K4 are propernationality factors, where K2 and K5 are time constants.
- the determination of the phase parameter at the beginning of each phase is delayed or, depending on threshold values, set back to the starting value at the start of milking or the values at the beginning of one of the past phases.
- the lower time limit of the integral is newly determined or MF P or or t p is set anew in the differential quotient: for example, this means the use of MF melt beguilt with regard to the start of the milking process.
- the parameters in relation to the determination of the phase evaluation variable can be set differently in all phases in order to take into account the different dynamics in the course of the milking process. This also applies to the amount of milk to be expected, which can differ in the individual phases.
- the determination of the phase evaluation variable at the end of the milking process up to the removal of the milking cluster with a separate set of parameters is useful, because a function-determining part of the function is resolved here.
- the threshold value for determining the end of the milking process is determined from the phase parameters for taking into account the duration of the individual phases.
- the threshold value can be determined by a linear combination of the phase parameters KG tj at the end of the phases j in connection with the evaluation variable.
- the threshold be used to determine the end of the milking process through the relationship
- K j should be phase-dependent factors
- BG tj evaluation parameters at times to and to + T and KG phase parameters.
- the characteristic variable KG at the beginning of the milking process, the evaluation variable BG, the threshold values SK and / or the target value is or are determined at least quarter-individually.
- the end of the milking process therefore follows. Individual udder irregularly shaped with damaged quarters are taken into account.
- the evaluation and characteristic variables " successive milking processes of the same cow are stored in order to arrive at good a priori settings.
- Fig. 1 shows schematically a first milk flow diagram
- Fig. 2 shows a second milk flow diagram
- FIG. 1 shows schematically the course of the milk flow over time.
- a setpoint S is specified.
- the value defines the start of a milking process.
- the start of the milking process is marked on the milking time axis with t 0 .
- an evaluation variable BGt 0 and a parameter KGt 0 are determined.
- a threshold value SK is determined and, if necessary, a forecast of the duration of the milking process.
- This threshold value SK is intended to determine the end of the milking process.
- the threshold value SK has a function of the parameter KG.
- a threshold value SK, 0 + T is determined . This threshold value also serves to determine the end of the milking process.
- an evaluation variable BG is determined which results from the current actual value of the milk flow, its change over time and the accumulated milk quantity.
- the evaluation size is preferably based on the relationship
- the end of the milking process is initiated when the evaluation variable BG essentially corresponds to the threshold value SK or falls below it.
- the threshold value SK can assume a higher or lower value, so that also changes the assessment variable BG required for acceptance accordingly.
- FIG. 2 shows a second diagram schematically showing the course of a milk flow.
- the milk flow can be divided into different phases.
- the milk flow is divided into a phase in which the cistern milk is extracted, the milking start, the main milking time and the final phase of milking.
- the evaluation values at the end of these milking phases are called KGtz home withdrawal of cistern milk, KG tb when milking starts, KGt h at the main milking time and KG te at the end of milking.
- the threshold values SKtp for determining the end in the different phases are noted analogously.
- the end of a milking phase is determined by considering the parameter KG t and comparing it with a threshold value SK assigned to this phase.
- the phase is considered to have ended when the threshold value of the associated phase essentially corresponds to the parameter or falls below it and a dependent time offset has also elapsed. This time offset can also disappear.
- a threshold value SK e for determining the end of the milking process is formed from the evaluation variables at the end of the milking phases KG z .
- the end of the milking process is initiated when the evaluation quantity only BG corresponds to the threshold value SK or falls below it.
- the milking process as such can be divided into further phases. Individual phases can also be merged.
- the area shown in FIGS. 1 and 2 below the milk flow curve after the milking process has ended corresponds to the amount of milk which will not be milked. This remaining milk is sufficiently small that it can be accepted. The course of the milk flow can be recorded continuously or discontinuously.
- Udder quarters that achieve a low evaluation size usually show a lower course of the milk flow curve over the entire milking process.
- the milking process ends here with a low threshold value, so that it is ensured that the milking process is not ended too early and the udder quarters are milked well empty.
- the setpoints are preferably set individually for the udder quarter, whereby the setpoints for the individual udder quarters can be different.
