Abstract

L'invention se rapporte au domaine de l'agriculture, concerne notamment des moyens de diagnostic de la santé et de l'état physiologique de bovins, et peut être utilisée notamment dans des fermes. Ce dispositif de mesure d'indices physiologiques individuels de bovins comprend un corps (1) avec un couvercle (2), dans lequel se trouve un microcontrôleur (7), une antenne (5), un marqueur RFID, des capteurs de mesure de température (8), de mesure du niveau de pH de l'estomac (9), du pouls (10), de mesure de la fréquence de réduction de la panse, et de mesure de l'activité motrice (12), un accumulateur (13) et des éléments de mémoire. Le corps (1) du dispositif comprend une ouverture avec une applique en caoutchouc (4), à travers laquelle passe l'extrémité d'une électrode du capteur de température (8) et de l'élément sensible du capteur de niveau de pH de l'estomac (9). Le corps (1) comprend une capsule de protection interne (6) se composant d'une carcasse métallique (6) recouverte de plastique, et un insert plastique de protection avec des fixations et dans lequel vient s'insérer une carte imprimée (3). L'invention permet d'augmenter la précision de détection d'écarts de l'état physiologique chez les bovins, d'améliorer les caractéristiques techniques du dispositif, et de simplifier l'accès aux éléments internes.
