Description




FIELD OF THE INVENTION




The invention relates to an automatic milking system for automatically milking animals.




BACKGROUND OF THE INVENTION




European Patent Application No. EP-A-0 576 086, of van der Lely, published Dec. 29, 1993, describes an automated milking apparatus in which malfunctions that occur are reported with the aid of a control system. The disadvantage of such apparatus is, inter alia, that it only reports that a particular component is not functioning. International Patent Application No. PCT/SE98/02386, Filed Dec. 18, 1998, International Publication No. WO 99/31967, published Jul. 1, 1999, of Eriksson, discloses an apparatus in which a cumulative value in relation to the useful life of a component is updated. When a threshold value has been reached, there is generated a signal indicating that the component has to be replaced. The disadvantage of this system is, inter alia, that the actual wear is not taken into account, so that components having a great divergence in their anticipated life are often replaced unnecessarily precipitately




SUMMARY OF THE INVENTION




The object of the invention is the improvement and further automation of the systems mentioned above. According to the invention this objective is achieved by monitoring and comparing data transmitted to a computer from measuring instruments provided in the automated milking apparatus relating to its functioning and on the basis thereof prognosticating anticipated failure of functions of the apparatus. The early determination of a diagnosis enables a user to be warned or a service mechanic to attend to required measures to avoid anticipated malfunctions, or both to occur. This enhances the reliability of the apparatus. Moreover, it may appear that a number of corrective measures can be delayed and taken care of during one visit by the service mechanic, which is cost-saving.











DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS OF THE INVENTION




Systems for automatically milking animals, such as cows, by means of a milking robot are well known by those skilled in the art. A milking robot is provided with means for automatically connecting teat cups to the teats of an animal to be milked. Said means comprise, for example, a robot arm and a sensor for detecting the position of the teats of the animal to be milked relative to the teat cups. There are further provided control means and other well known components such as cleaning means, a feeding device, an animal identification system and a milk reservoir. The control means may comprise a computer which is connected, or capable of being connected, with a number of measuring instruments (sensors) which are related to functions of the apparatus, such as the milking process or parts thereof, the pre-treatment of an animal to be milked, the cleaning of the teats of an animal to be milked, the cleaning of the teat cups, the feeding of an animal to be milked, and measurements of the quantity of milk yielded.




A monitoring program for said functions is programmed or installed in the computer. The computer includes reference data which are related to said functions. The measuring instruments which are also related to said functions provide data to the computer. With the aid of the monitoring program the computer is suitable for determining, on the basis of a comparison of data from one or more of the measuring instruments with the reference data, a diagnosis in relation to an anticipated fault in one or more of said functions. The monitoring program attributes a diagnosis for an anticipated malfunction to certain combinations of measurement data and reference data, as will be elucidated hereinafter. On the basis of the diagnosis it is possible to intervene before the malfunction actually occurs.




The computer may be programmed such that the diagnosis comprises the anticipated nature of the malfunction, the anticipated point of time or an anticipated time interval for the malfunction to occur. The computer is preferably programmed so that the diagnosis comprises a warning to a user or a service mechanic, or both. In this manner the system or function or component involved is checked in time (before the malfunction actually occurs) whether action has to be taken in relation to a particular function or a particular component. In clear cases the diagnosis may also comprise a concrete instruction to the user or the service mechanic, or both, in order to prevent the anticipated malfunction. Such an instruction may comprise an action to be taken by the user or the service mechanic, as appropriate, and a time indication within which the action should be taken.




In a preferred embodiment of the invention the diagnosis comprises an indication to the user or the service mechanic or to both to check the condition of a component which is related to the anticipated malfunction and to repair or to replace said component if necessary. Thus it is possible to establish in an early stage whether the actual wear or abnormality of the component requires its repair or replacement of the relevant component at once. When it appears that for example the actually occurred wear is smaller than would have been anticipated on the basis of the age or the use of the component, it may be decided to continue to use the relevant component for a certain further time. This is cost-saving, of course. The monitoring program supplies an appropriate warning in an early stage so that malfunctions in the system can be avoided.




The computer may be suitable for selecting the diagnosis out of an available collection of diagnoses related to said functions. A great number of diagnoses of possible malfunctions may be stored in the computer. The collection of diagnosis may then at least partially depend on the size of the herd of animals to be milked. With a small herd there may be other problems leading to malfunctions than with a large herd. In this manner the number of animals that will make use of the system can be taken into account.




The system is preferably provided with means enabling it to adapt or to extend the available collection of diagnoses, or to do both. The system may thus be adapted to the specific needs and circumstances of the dairy farm where the construction is used. With some dairy farms malfunctions may occur that are hardly likely to occur at other dairy farms. The means may be suitable for adapting diagnoses or adding new diagnoses on the basis of the patterns of data from the measuring instruments established during the use of the apparatus. When it appears for example that during the failure-free use of a certain component there is continuously generated a malfunction diagnosis, then the computer may conclude that this diagnosis is not correct. In this manner the disadvantageous results of incorrect reference data can be corrected automatically. It is also possible to add a corresponding, improved diagnosis when a particular fault in a particular function occurs a number of times earlier than would have been expected on the basis of the existing diagnosis. The collection of diagnosis is thus automatically adapted to the local circumstances of the construction.




The means may be suitable for adapting or extending the available collection of diagnoses, or doing both, based on the size of the herd of animals to be milked or the (possibly measured) intensity with which the apparatus is used. The fact is that these parameters may strongly influence the nature and the frequency of anticipated malfunctions. Of course, there are also other influences, such as, for example, the degree of contamination of the environment in which the system is used. In a clean shed fewer problems will occur than in a highly contaminated one.




The apparatus is suitable for indicating, for example visually or acoustically or both, the diagnosis determined by the computer, or at least the instruction pertaining thereto.




The measuring instruments may comprise sensors, clocks or counters or a combination thereof. There may for example be provided a sound sensor by means of which it is possible to detect sounds that deviate from reference patterns. On the basis of the measurements it is possible for example to generate a diagnosis having for instruction “check vacuum pump” or “replace pulsator within 24 hours.” It is also possible to use sensors for measuring the electricity consumption of certain components, the air consumption, the water consumption, the milk-discharge, the feed supply, the conductivity of cleaning liquid, the temperature in the bulk milk cooling tank, the pulsation pattern in the teat cups, etc. With the aid of time sensors or clocks it is possible to determine for example (cumulative) consumption times of components, connection times of the teat cups, time required for establishing a vacuum, etc. By means of counting sensors or counters it is possible for example to determine the number of pulsations of a pulsator or the number of times a component is used.




The reference data may comprise an interval for a measured value to be determined by means of one or more measuring instruments. The monitoring program selects for example the diagnosis “sound level too high; check vacuum pump” when the measured sound level of a vacuum pump is above 70 decibels for at least 30 seconds. The reference data may also comprise an anticipated life or an anticipated failure-free useful life for a function-related component of the construction. When the point of time is reached at which, for example, 90% of the useful life of a component has elapsed, the instruction may be “check the condition of component within six hours and determine whether it must be replaced; if not, provide new time interval for further use.”




The computer is preferably suitable for determining in a parallel manner more than one diagnosis and for attributing an urgency to each diagnosis. The system is then capable of indicating the diagnosis determined or at least the instructions pertaining thereto in order of urgency. This enhances the user-friendliness of the construction.




The apparatus may comprise a number of components known per se, such as coils and motors for driving and controlling other components, a compressor, a vacuum pump and an air system connected therewith with air lines and valves, a pulsator wherein pulsation speed and pulsation ratio are adjustable, a cleaning system with a water pump, a water tank with a three-way-valve and liquid lines, teat cups with liners, and openings to receive teats, a tilting mechanism and a cord, milk lines, milk meters, milk filters, a milk glass with a float, a bulk milk cooling tank with a contents meter, a feeding system with a feeding trough, a feed auger and a weighing cell, a floor element with a weighing device and weighing cells, conductivity sensors, cleaning means with lye or acid or both, milk separation means, a laser measuring system for determining teat positions with a laser widow, lifting piston and cylinder members for the teat cups, stepper motors and other drive mechanisms for having certain movements performed by certain components, milk flow sensors, milk pulsation tubes with tube shut-off valves, a bulk milk cooling tank with a cooling system and a cleaning system, an entrance and an exit with gates of a milking compartment, an animal identification system, etc.




The computer may for example be programmed such that when one or more measuring instruments establish an increasing electricity consumption, it is determined that rinsing or motors or both should be checked.” But, the diagnosis or warning issued need not contain literally the words “check rinsing or motors or both,” it may simply indicate that a problem with rinsing or motors or both may be anticipated.




From the foregoing, it will be appreciated that the invention relates to an apparatus for automatically milking animals which is provided with a milking robot and a computer which is capable of being connected with a number of measuring instruments that are related to a number of condition parameters relating to an animal to be milked as well as to components of the apparatus. According to the invention a monitoring program for said parameters is installed in the computer, with the aid of which the computer is suitable for determining, on the basis of a comparison of data from one or more of the measuring instruments with reference data related to said parameters, a diagnosis based on an anticipated undesired deviation in one or more of said parameters. Again the early determination of a diagnosis enables a user or a veterinarian to be warned so that one or the other or both can take timely measures to avoid or ameliorate the anticipated undesired problems.




The computer may further be suitable for continuously adapting the reference data on the basis of measured quantities. The computer may also be suitable for automatically generating reference data. The reference data may be based on the herd of animals to be milked or on the intensity with which the apparatus is used.




The construction is preferably provided with means for transmitting the diagnosis determined by the computer by telephone or as SMS-message, or both, to a user or a service mechanic, or both. In this manner the user or the service mechanic, or either, as appropriate, is able to react promptly.




The computer may be programmed so that when one or more measuring instruments reflect a slowly starting milk flow profile, the computer recommends: “prolong pre-treatment.”
