Abstract: A method of monitoring a milking process by a milking apparatus that includes a teatcup with a pulsation space and an airline to deliver varying levels of pressure to the pulsation space. The method includes: measuring airflow within the airline to obtain an indication of volume of displaced air within the pulsation space; comparing the volume with a reference value; and determining a connection parameter, indicating how the teatcup is connected to the teat, based on the comparison. The displaced air volume correlates to the extent the teat protrudes into the teatcup, thus providing information on how the teatcup is connected. Also provided is a milking system incorporating the method.
Abstract translation: 一种通过挤奶设备监测挤奶过程的方法，所述挤奶设备包括具有脉动空间的乳头杯和航空公司，以向脉动空间输送不同程度的压力。 该方法包括：测量航空公司内的气流以获得在脉动空间内的移动空气体积的指示; 将体积与参考值进行比较; 以及基于所述比较，确定指示所述奶头杯与乳头连接的连接参数。 移动的空气量与乳头伸入乳头杯的程度相关，从而提供关于乳头杯连接如何的信息。 还提供了一种结合该方法的挤奶系统。

Abstract: A system for removing manure from a floor in a barn for animals, such as cows, includes an autonomous manure removing vehicle, which is provided with a drive system. The drive system includes at least one electric drive motor. An electronic control system is connected to the drive system for control thereof. A battery system for storing electrical energy is connected to the drive system and the control system. The system includes a charging station for charging the battery system. The charging station includes a transmitting body with a primary coil. The manure removing vehicle includes a receiving body with a secondary coil. The receiving body is fastened rigidly to the manure removing vehicle. The transmitting body of the charging station is pretensioned to a waiting state, and is movable from the waiting state against the action of the pretension, through engagement with the receiving body of the manure removing vehicle that enters the charging station, in such a way that the primary coil of the transmitting body and the secondary coil of the receiving body are mutually aligned in a charging state to transfer electrical energy wirelessly from the primary coil to the secondary coil for wireless charging of the battery system.

Abstract: A milking device for milking a dairy animal comprises a teat cup with a cup wall and a teat liner and a pulsation space situated in between, to which pulsation space a pulsation device is connected which is configured to apply a pressure that varies in pulsations to the pulsation space in order to open and close the teat liner, and which pulsation device comprises a supply line which is controllable by a first operable valve, in particular closable, for supplying a first pressure, a supply line which is controllable by a second operable valve, in particular closable, for supplying a second pressure, which is a lower pressure than the first pressure, and a control unit which is configured to generate control signals for operating the first valve and the second valve, wherein the first valve, and preferably also the second valve, is a controllable valve having a passage which is adjustable by means of the control signals, wherein the passage of the first valve, and preferably of the second valve, respectively, is adjustable during at least one pulsation phase by the control unit via the control signals.

Abstract: The invention provides a milking device comprising at least one milking cup with a teat space and a pulsation space, a pulsator connected by means of a pulsation line to the pulsation space of the milking cup and provided with a vacuum source, a vacuum line provided with a first controllable valve between the vacuum source and the pulsation line, an aeration line provided with a second controllable valve between the pulsation line and a source of higher pressure, and a pulsator control system for the first and second valves, wherein the pulsator control system comprises a flushing mode for opening and holding open the first and second valves during at least a predefined flushing time which is at least as long as and preferably longer than the pulsation period. In this way it is possible to have both valves open simultaneously and the pulsator will draw in air from the environment in an initially unhindered flow. This flow may be used for example to flush the system with air (“blow through”) but also for example to measure the air flow and/or pressure drops in the system, and on the basis thereof to determine the degree of soiling of the system.

Abstract: A sampling device for taking a representative milk sample from a milking device. The milking device includes a milking means, a milk jar, a milk hose, a milk tank, a milk line, a milk pump for pumping the milk, a milk meter for determining the quantity of milk milked, and a control unit. The sampling device includes a sample line with an input connection to the milk jar, the milk pump or the milk line, an output to a sample collection receptacle, and a control device controllable by the control unit based on the quantity of milk determined by the milk meter in order to direct, during pumping, a sample quantity of milk through the sample line. The control unit knows how much milk must be pumped and can take precisely enough milk samples distributed over the pumping operation such that an accurate representative sample is obtained.
