Title (EN) POSITION DETECTION SYSTEM
(FR) SYSTÈME DE DÉTECTION DE POSITION
(JA) 位置検出システム
Abstract:
(EN) [Problem] To provide a position detection system capable of accurately detecting the position of a moving body, even when the moving body moves inside a warehouse. [Solution] A position detection system 100 comprises: a plurality of fixed stations 20; and a sensor unit 10 which has an inertia sensor that detects the movement history of a moving body 51 and a range sensor that detects a separation distance between the moving body 51 and the fixed stations 20. The position detection system 100: detects a first arrival position P1 obtained on the basis of the movement history, a second arrival position P2 obtained on the basis of the separation distance, and a relative distance L1 between the first arrival position P1 and the second arrival position P2; and determines the position of the moving body 51 by comparing the relative distance L1 and a range value R1 obtained on the basis of the movement history. The size of the range value R1 varies on the basis of the movement history.
(FR) Le problème décrit par l'invention est de fournir un système de détection de position permettant de détecter avec précision la position d'un corps mobile, même lorsque le corps mobile se déplace à l'intérieur d'un entrepôt. La solution selon l'invention porte sur un système de détection de position 100 comprenant : une pluralité de postes fixes 20 ; et une unité capteur 10 qui comporte un capteur d'inertie qui détecte l'historique de déplacement d'un corps mobile 51 et un capteur de distance qui détecte une distance de séparation entre le corps mobile 51 et les postes fixes 20. Le système de détection de position 100 détecte une première position d'arrivée P1 obtenue sur la base de l'historique de déplacement, une seconde position d'arrivée P2 obtenue sur la base de la distance de séparation, et une distance relative L1 séparant la première position d'arrivée P1 de la seconde position d'arrivée P2 ; et détermine la position du corps mobile 51 en comparant la distance relative L1 et une valeur de plage R1 obtenue sur la base de l'historique de déplacement. L'importance de la valeur de plage R1 varie sur la base de l'historique de déplacement.
(JA) 【課題】移動体が倉庫内を移動する場合であっても、移動体の位置を正確に検出することが可能な位置検出システムを提供する。 【解決手段】複数の固定局20と、移動体51の移動履歴を検出する慣性センサ及び移動体51と固定局20との間の離間距離を検出する測距センサを有したセンサユニット10と、を備え、移動履歴に基づいて得られる第1到達位置P1と、離間距離に基づいて得られる第2到達位置P2と、第1到達位置P1と第2到達位置P2との間の相対距離L1と、を検出し、移動履歴に基づいて得られる範囲値R1と相対距離L1とを比較することによって、移動体51の位置を確定する位置検出システム100であって、範囲値R1の大きさを、移動履歴に基づいて変化させる。
