Title (EN) POSITION DETECTING SYSTEM AND POSITION DETECTING METHOD

Abstract: front page image
(EN) A position detecting system (1) is provided with a mobile station (2), a reference station (3), fixed stations (4) to (6), and a server (7). The mobile station (2) transmits a first radio signal S1, and the reference station (3) transmits a second radio signal S2 a plurality of times. The fixed stations (4) to (6) extract a first phase difference based on the first radio signal S1, and extract a second phase difference based on the second radio signal S2. On the basis of a plurality of the second phase differences, the server (7) calculates a third phase difference by obtaining the time variation of the second phase differences. The server (7) cancels phase offsets of the fixed stations (4) to (6) using phase difference information between the mobile station (2) and the fixed stations (4) to (6) and phase difference information between the reference station (3) and the fixed stations (4) to (6), obtains distance information between the fixed stations (4) to (6) and the mobile station (2), and calculates the position of the mobile station (2).
(FR) La présente invention concerne un système de détection de position (1) qui est pourvu d'une station mobile (2), d'une station de référence (3), de stations fixes (4) à (6), et d'un serveur (7). La station mobile (2) émet un premier signal radio S1, et la station de référence (3) émet un deuxième signal radio S2 plusieurs fois. Les stations fixes (4) à (6) extraient un premier déphasage sur la base du premier signal radio S1, et extraient un deuxième déphasage sur la base du deuxième signal radio S2. Sur la base d'une pluralité des deuxièmes déphasages, le serveur (7) calcule un troisième déphasage en obtenant la variation temporelle des deuxièmes déphasages. Le serveur (7) annule les décalages de phase des stations fixes (4) à (6) en utilisant des informations de déphasage entre la station mobile (2) et les stations fixes (4) à (6) et des informations de déphasage entre la station de référence (3) et les stations fixes (4) à (6), obtient des informations de distance entre les stations fixes (4) à (6) et la station mobile (2), et calcule la position de la station mobile (2).
(JA) 位置検知システム(1)は、移動局(2)と基準局(3)と各固定局(4)~(6)とサーバ(7)とを備えている。移動局(2)は第1の無線信号S1を送信し、基準局(3)は第2の無線信号S2を複数回送信する。各固定局(4)~(6)は、第1の無線信号S1に基づく第1の位相差を抽出し、また、第2の無線信号S2に基づく第2の位相差を抽出する。サーバ(7)は、複数の第2の位相差に基づいて第2の位相差の時間変動を求めて第3の位相差を算出する。サーバ(7)は、移動局(2)と各固定局(4)~(6)との間の位相差情報と、基準局(3)と各固定局(4)~(6)との間の位相差情報とを用いて、各固定局(4)~(6)の位相オフセットをキャンセルし、各固定局(4)~(6)と移動局(2)との間の距離情報を得て、移動局(2)の位置を算出する。
