Title
(EN) DEVICE AND AGRICULTURAL DEVICE FOR MEASURING WATER PRESENT IN VEGETATION AND OPERATION METHOD THEREOF
(FR) DISPOSITIF ET DISPOSITIF AGRICOLE POUR MESURER L'EAU PRÉSENTE DANS DE LA VÉGÉTATION ET PROCÉDÉ DE FONCTIONNEMENT ASSOCIÉ
Abstract
(EN)
Device and agricultural device, and operation method thereof, for measuring plant water present in vegetation comprising: an microwave emitter of a displaceable beam; a microwave receiver; an electronic data processor connected to receive a signal from the microwave receiver; wherein the microwave emitter is arranged to direct said displaceable beam towards the microwave receiver for measuring attenuation of the beam passing through each of a plurality of locations of the vegetation; wherein the electronic data processor is configured for calculating the attenuation of the displaceable beam between the emitter and receiver to obtain a 2D image corresponding to the measurement of water present in the vegetation. In particular, said beam is displaceable by the device being mounted on a vehicle which is movable along the vegetation to be measured in a horizontal direction, the microwave emitter and microwave receiver being jointly mounted in opposite ends of an arched structure.
(FR)
L'invention concerne un dispositif et un dispositif agricole, et un procédé de fonctionnement de ceux-ci, pour mesurer l'eau des plantes présente dans de la végétation, comprenant : un émetteur de micro-ondes d'un faisceau apte à être déplacé ; un récepteur de micro-ondes ; un processeur électronique de données connecté pour recevoir un signal à partir du récepteur de micro-ondes ; l'émetteur de micro-ondes étant conçu pour diriger ledit faisceau apte à être déplacé en direction du récepteur de micro-ondes pour mesurer l'atténuation du faisceau traversant chacun d'une pluralité d'emplacements de la végétation ; le processeur électronique de données étant configuré pour calculer l'atténuation du faisceau apte à être déplacé entre l'émetteur et le récepteur pour obtenir une image bidimensionnelle, 2D, correspondant à la mesure de l'eau présente dans la végétation. En particulier, ledit faisceau est apte à être déplacé par le dispositif monté sur un véhicule qui est mobile le long de la végétation à mesurer dans une direction horizontale, l'émetteur de micro-ondes et le récepteur de micro-ondes étant montés conjointement à des extrémités opposées d'une structure arquée.
