Abstract

La présente invention est caractérisée en ce qu'elle comprend : un tube isolant (30) qui est ajusté autour de l'extérieur d'une borne de broche (34) qui connecte une borne (12) d'un dispositif électrique (10) et une ligne électrique (20) ; un capteur de température (32) inséré dans le tube isolant (30) pour émettre un signal de détection de température, lequel est obtenu en détectant la température ambiante, par le biais d'une ligne de signal ; un arrière-plan de référence (40) qui est situé derrière le tube isolant (30) et dans lequel plusieurs lignes droites sont dessinées à intervalles réguliers ; une caméra (50) qui capture des images du tube isolant (30) de sorte que l'arrière-plan de référence (40) soit visible vers l'arrière, et qui émet des signaux d'images ; et une unité de contrôle (60) qui détermine qu'une surchauffe causée par une surcharge de la borne de broche (34) s'est produite et qui émet un signal d'alerte lorsque le signal de détection de température émis par le biais de la ligne de signal et les signaux d'images capturés par la caméra (50) sont reçus, et qu'une valeur de température selon le signal de détection de température est égale ou supérieure à une valeur définie. L'unité de contrôle (60) obtient une image non distordue du tube isolant (30) parmi les images selon les signaux d'images en associant et en corrigeant toutes les images tout en corrigeant les distorsions des lignes droites dessinées dans l'arrière-plan de référence (40).
