Title (EN) MOVEMENT-DISTANCE MEASUREMENT DEVICE
(FR) DISPOSITIF DE MESURE DE DISTANCE DE DÉPLACEMENT
(JA) 移動距離計測装置
Abstract:
(EN) Provided is a movement-distance measurement device (10) comprising: an antenna (12) for transmitting radio waves towards a plurality of reflectors (9) disposed at fixed disposition intervals along a movement path of a moving body and receiving reflected waves from the reflectors (9); a phase detection circuit (15) for detecting the phase of the reflected waves received by the antenna (12); a phase change amount calculation circuit (16) for calculating a change amount of the phase on the basis of the phase detected by the phase detection circuit (15); and a movement-distance calculation circuit (17) for calculating a movement distance of the moving body on the basis of the change amount of the phase calculated by the phase change amount calculation circuit (16) and the disposition intervals of the reflectors (9).
(FR) L'invention concerne un dispositif de mesure de distance de déplacement (10) comprenant : une antenne (12) servant à transmettre des ondes radio vers une pluralité de réflecteurs (9) disposés à des intervalles de disposition fixes le long d'un trajet de déplacement d'un corps mobile et à recevoir des ondes réfléchies à partir des réflecteurs (9) ; un circuit de détection de phase (15) servant à détecter la phase des ondes réfléchies reçues par l'antenne (12) ; un circuit de calcul de quantité de déphasage (16) servant à calculer une quantité de déphasage sur la base de la phase détectée par le circuit de détection de phase (15) ; et un circuit de calcul de distance de déplacement (17) servant à calculer une distance de déplacement du corps mobile sur la base de la quantité de déphasage calculée par le circuit de calcul de quantité de déphasage (16) et des intervalles de disposition des réflecteurs (9).
