Title (EN) MOVING BODY POSITIONING SYSTEM AND LOGISTICS MANAGEMENT SYSTEM
(FR) SYSTÈME DE POSITIONNEMENT DE CORPS MOBILE ET SYSTÈME DE GESTION LOGISTIQUE
(JA) 移動体測位システムおよび物流管理システム
Abstract:
(EN) A moving body positioning system (100) according to the present disclosure is provided with: a moving body (10) including an array antenna (12) and a processing circuit (14); a plurality of beacons (20) which are provided in prescribed positions and each of which periodically or intermittently radiates a signal wave including identification information; and a storage device (40) which stores data associating the items of identification information with the respective positions of the plurality of beacons (20). The array antenna (12) includes a plurality of antenna elements, sequentially or simultaneously receives the signal waves radiated from each of the plurality of beacons (20), and outputs an array signal. The processing circuit reads the identification information from the received signal waves, and refers to the data to determine the position of at least one beacon that radiated the signal waves, on the basis of the identification information. The processing circuit estimates the arrival direction of the signal wave on the basis of the array signal, and performs positioning of the moving body on the basis of the position of the at least one beacon that radiated the signal wave and the estimated signal wave arrival direction.
(FR) Un système de positionnement de corps mobile (100) selon la présente invention comprend : un corps mobile (10) comprenant une antenne réseau (12) et un circuit de traitement (14) ; une pluralité de balises (20) qui sont disposées dans des positions prescrites et dont chacune rayonne périodiquement ou par intermittence une onde de signal comprenant des informations d'identification ; et un dispositif de stockage (40) qui stocke des données associant les éléments d'informations d'identification aux positions respectives de la pluralité de balises (20). L'antenne réseau (12) comprend une pluralité d'éléments d'antenne, reçoit séquentiellement ou simultanément les ondes de signal rayonnées à partir de chacune de la pluralité de balises (20), et délivre un signal de réseau. Le circuit de traitement lit les informations d'identification à partir des ondes de signal reçues, et se réfère aux données pour déterminer la position d'au moins une balise qui a rayonné les ondes de signal, sur la base des informations d'identification. Le circuit de traitement estime la direction d'arrivée de l'onde de signal sur la base du signal de réseau, et effectue un positionnement du corps mobile sur la base de la position de la ou des balises qui rayonnent l'onde de signal et la direction d'arrivée d'onde de signal estimée.
(JA) 本開示の移動体測位システム(100)は、アレーアンテナ(12)および処理回路(14)を有する移動体(10)と、所定の位置に配置され、それぞれが識別情報を含む信号波を周期的または断続的に放射する複数のビーコン(20)と、各識別情報を複数のビーコン(20)のそれぞれの位置に関連づけるデータを格納する記憶装置(40)とを備える。アレーアンテナ(12)は、複数のアンテナ素子を有し、複数のビーコン(20)のそれぞれから放射された信号波を順次または同時に受信してアレー信号を出力する。処理回路は、受信した信号波から識別情報を読み出し、データを参照し、識別情報に基づいて信号波を放射した少なくとも1個のビーコンの位置を決定する。処理回路は、アレー信号に基づいて信号波の到来方向を推定し、信号波を放射した少なくとも1個のビーコンの位置および推定された信号波の到来方向に基づいて前記移動体の測位を行う。
