Abstract

La présente invention concerne un équipement de détection de risque de givrage d'une surface exposée à un flux de gouttelettes par caractérisation physique et thermochimique d'un brouillard de gouttelettes de dimensions comprises entre 1 et 500 µm, dans une zone de mesure (ZM) comprenant des moyens d'illumination (1) susceptibles de réaliser une illumination de ladite zone de mesure (ZM), des moyens de prise de vue (2) comportant au moins une caméra (3) susceptible de prendre au moins une image de ladite zone de mesure (ZM) illuminée par lesdits moyens d'illumination (M1), et des moyens de traitement (4) susceptibles de déterminer les valeurs dudit paramètre, à partir de ladite image prise par la caméra (3). L'équipement comporte en outre un circuit de traitement de l'image transmise par la caméra et un calculateur pour commander la numérisation et l'enregistrement les images dans une mémoire locale.The present invention relates to equipment for detecting the risk of icing of a surface exposed to a flow of droplets by physical and thermochemical characterization of a mist of droplets of dimensions between 1 and 500 μm, in a measurement zone (ZM). comprising illumination means (1) capable of providing illumination of said measurement zone (ZM), image-taking means (2) comprising at least one camera (3) capable of taking at least one image of said zone measuring device (ZM) illuminated by said illumination means (M1), and processing means (4) capable of determining the values of said parameter, from said image taken by the camera (3). The equipment further includes a circuit for processing the image transmitted by the camera and a computer for controlling the digitization and recording of the images in a local memory.
