Abstract: A rotary milking parlor arrangement contains a rotating platform with stalls configured to house a respective animal during milking, a set of at least three drive units causing the rotating platform to move in a first rotational direction, and a primary control unit controlling operation of each drive unit in the set of drive units. A set of links connect the drive in a ring network in including the primary control unit. Each link is bi-directional. The primary control unit identifies any single faulty link in the set of links by: transmitting a first signal in a clockwise direction through the ring network, transmitting a second signal in a counter clockwise direction through the ring network, and checking how far the first and second signals can be transmitted through the ring network in the clockwise and counter clockwise direction respectively without being interrupted by the single faulty link.

Abstract: Tools in an automatic milking arrangement are picked up by using a robotic arm (110). The robotic arm (110) moves a camera (130) to an origin location (PC) from which the camera (130) registers three-dimensional image data (Dimg3D) of at least one tool (141, 142, 143, 144). The three-dimensional image data is processed using an image-based object identification algorithm to identify objects in the form of the tools and hoses (152). In response to identifying at least one tool, a respective tool position (PT1, PT3, PT4) is determined for each identified tool based on the origin location (PC) and the three-dimensional image data. Then, a grip device (115) is exclusively controlled to the one or more of the respective tool positions (PT1, PT3, PT4) to perform a pick-up operation. Thus, futile attempts to pick-up non-existing or blocked tools can be avoided.

Abstract: A system and method for automatically matching a sensor device attached to an animal with an ID tag attached to the animal, wherein a reader device, located in or alongside a passage of an animal enclosure, transmits a signal toward the animal in the passage that triggers the ID tag to transmit ID information, and a monitoring device in communication with the reader device receives the ID information from the reader device, receives sensor device information from the sensor device including a sensor device identity, and determines that the ID tag and the sensor device are attached to a same animal based on time information associated with the ID information and the sensor device information.

Abstract: A message handling node of a farm management system that receives error messages from a plurality of automatic devices, and generates and sends out error reports to user terminals, where the message handling node applies a rules system prescribing that an error report concerning a particular one of the automatic devices is generated based on fulfillment of a frequency criterion relating to a number of times at which the message handling node receives the error messages from said particular one device within at least one previous period in order to manage a total number of error reports received by each of the user terminals.

Abstract: A control valve and a membrane for a moving a valve disk of a control valve between a first position and a second position are provided. The membrane has a central axis perpendicular to an extension plane of the membrane. The membrane includes an outer annular rim portion, a central portion configured to be connected the valve disk, and a flexible portion that is annular and provided between the central portion and the outer annular rim portion. The membrane is flexible to permit the central portion to move back and forth along the central axis, thereby permitting the valve disk to move to one of the first position and the second position. The membrane is designed with an inherent pre-tensioning of the flexible portion, which permits the membrane to exert a force on the valve disk from the first position towards the second position.

Abstract: An offset for a first milking tool in a tool carrier of an automatic milking machine is determined as a spatial vector between a tool reference position (TRP) and an estimated actual position (TAP) of the milking tool. A three-dimensional image data is registered that represents a teat (T) during attachment to and/or detachment from the milking tool. The image data is processed by searching, within a search zone, for a predefined part (MP) of the teat (T) while the teat (T) is attached to the milking tool. Provided that the predefined part (MP) fulfills a measurement criterion, a distance (doff) is calculated between a specific point of the predefined part (MP) and the tool reference position (TRP). The offset is then determined based on the calculated distance (doff).
