Abstract

A milking system for milking a dairy animal includes a milking cup to be attached to a teat of the dairy animal and milking the milk, and an electronic component. The electronic component includes a sensor which is arranged in or on the milking cup for measuring a value of a variable related to the milking, a transmitter for transmitting the measured values, and a power supply for supplying the sensor and/or the transmitter with electrical energy. The power supply may include an inductive power supply with a first coil component and a second coil component, where the first coil component and the electronic component are electrically connected to each other, and where the second coil component is electrically directly connectable to an external source of electrical energy. The milking system also includes a fastening means which holds the first coil component and the second coil component together.

First claim

The invention claimed is:

1. A milking system for milking a dairy animal, comprising:
a milking cup to be attached to a teat of the dairy animal and milking milk from the dairy animal, and
an electronic component with a sensor which is arranged in or on the milking cup for measuring a value of a variable related to the milking, a transmitter for transmitting the measured values, and a power supply for supplying the sensor and/or the transmitter with electrical energy,
wherein the power supply comprises an inductive power supply with a first coil component and a second coil component,
wherein the first coil component and the electronic component are electrically connected to each other in a direct and fixed manner, and wherein the second coil component is electrically directly connectable to an external source of electrical energy,
wherein the milking system furthermore comprises a fastening means which holds the first coil component and the second coil component together such that the first coil component and the second coil component remain inductively connected, even during milking.

2. The milking system as claimed in claim 1 , wherein the fastening means is detachable by a user in order to replace the second coil component or the milking cup.

3. The milking system as claimed in claim 1 , further comprising an external source of electrical energy which is electrically connected to the second coil component by an external current conductor.

4. The milking system as claimed in claim 3 , wherein the second coil component comprises a housing containing a coil and a connection between the coil and the external current conductor which connection is integrally molded on or cast in.

5. The milking system as claimed in claim 3 , wherein the transmitter is configured to transmit the measured value via the first coil component, the second coil component and the external current conductor.

6. The milking system as claimed in claim 5 , wherein the transmitter comprises a modulator in order to provide a voltage signal on the first coil component, which voltage signal is modulated as a function of the measured value.

7. The milking system as claimed in claim 3 , wherein the external current conductor is an electric wire.

8. The milking system as claimed in claim 1 , wherein the transmitter comprises a wireless transmitter.

9. The milking system as claimed in claim 8 , wherein the wireless transmitter comprises a transmitter from the group selected from a Near-Field Communication device and an optical transmitter.

10. The milking system as claimed in claim 8 , wherein the wireless transmitter comprises an infrared transmitter.

11. The milking system as claimed in claim 1 , wherein the milking cup comprises an energy store which is configured to be charged by means of the power supply.

12. The milking system as claimed in claim 11 , wherein furthermore the power supply is configured to detect if the electrical power supply is lost in at least the first coil component and the transmitter is configured to transmit an alarm signal, depending on said detection.

13. The milking system as claimed in claim 1 , wherein the milking system is a milking robot.
