Animal e.g. herd, identification system diagnostic method for milking installation, involves determining scanner dependent parameter from information containing animal individual code, and comparing parameter with reference parameter

摘要

The method involves optically detecting information, which contains an individual code of an animal, using scanners (6, 7) of an animal identification system. A scanner dependent parameter is determined from the detected information, and the determined parameter is compared with a reference parameter, which is derived from a number of animals to be identified. Strength of the signals of transponders is determined and stored. Independent claims are also included for the following: (1) a diagnostic device for an animal identification system (2) a milking installation comprising an animal identification system.
