Abstract
A rotary milking parlor controlled that uses a set of sensors generating sensor signals that determine whether or not an entity is located at a hazardous position of the rotary milking parlor, and a central control unit, where each sensor in the set of sensors generates first and second independent signals, the first and second signals conveyed separately via respective first and second signal lines to the central control unit, and the rotary milking parlor controlled to be operated only if both the first and second signals of all sensors in the set of sensors indicate that no entity is deemed to be located at a hazardous position.
Claims16
A control system for a rotary milking parlor (100), the control system comprising:
- a set of sensors configured to generate sensor signals (SS) indicating conditions reflecting whether or not an entity is located at a position relative to the rotary milking parlor (100) that is hazardous for the entity (A, H) with respect to a current operation (RF, RR) of the milking parlor (100);
- and
- a central control unit (230) configured to receive the sensor signals (SS) and control the rotary milking parlor (100) according to a predetermined operation procedure and in response to the sensor signals (SS),
- wherein each sensor in the set of sensors is configured to generate first and second signals both for detecting a condition at the hazardous position, said first and second signals being independent from one another and conveyed separately by respective first and second signal lines of the control system to convey the first and second signals to the central control unit (230), and
- wherein the central control unit permits the rotary milking parlor (100) to be operated only on condition that both the first and second signals of all the sensors in the set of sensors indicate that no entity (A, H) is located at any hazardous position.
A method of controlling a rotary milking parlor (100), the method comprising:
- generating, via a set of sensors sensor signals (SS) indicating conditions reflecting whether or not an entity (A, H) is located at a position relative to the rotary milking parlor (100) that is hazardous for the entity (A, H) with respect to a current operation (RF, RR) of the milking parlor (100);
- and
- controlling the rotary milking parlor (100) according to a predetermined operation procedure and in response to the sensor signals (SS), each sensor in the set of sensors configured to generate both first and second signals for detecting a condition at the hazardous position, said first and second signals being independent from one another;
- conveying the first and second signals separately via respective first and second signal lines;
- and
- controlling the rotary milking parlor (100) such that the rotary milking parlor (100) operates only on condition that both the first and second signals of all the sensors in the set of sensors indicate that no entity (A, H) is located at any hazardous position.
