Abstract

(EN) An indoor network communication device positioning method, used for positioning of at least one device end (AP, AP1, AP2, AP3) provided in an indoor area. The method comprises the following steps: S1, acquiring an initial position (A0, B0) of a mobile terminal (1, 1A, 1B) by means of satellite positioning; S2, on the basis of inertial navigation and the initial position (A0, B0), acquiring a plurality of anchor positions (A1, A2, A3, B1, B2, B3) of the mobile terminal (1, 1A, 1B) in the indoor area; S3, the mobile terminal (1, 1A, 1B) performing measurement at the plurality of anchor positions (A1, A2, A3, B1, B2, B3) so as to obtain a plurality of measured distances to the at least one device end (AP, AP1, AP2, AP3), each anchor position (A1, A2, A3, B1, B2, B3) corresponding to one measured distance; and, on the basis of a positioning algorithm, analyzing the plurality of anchor positions (A1, A2, A3, B1, B2, B3) and the plurality of measured distances to calculate an installation position of the at least one device end (AP, AP1, AP2, AP3) in the indoor area.

(FR) L'invention concerne un procédé de positionnement de dispositif de communication de réseau intérieur, utilisé pour positionner au moins une extrémité de dispositif (AP, AP1, AP2, AP3) disposée dans une zone intérieure. Le procédé comprend les étapes suivantes : S1, acquisition d'une position initiale (A0, B0) d'un terminal mobile (1, 1A, 1B) au moyen d'un positionnement par satellite ; S2, en fonction de la navigation inertielle et de la position initiale (A0, B0), acquisition d'une pluralité de positions d'ancrage (A1, A2, A3, B1, B2, B3) du terminal mobile (1, 1A, 1B) dans la zone intérieure ; S3, le terminal mobile (1, 1A, 1B) effectuant une mesure au niveau de la pluralité de positions d'ancrage (A1, A2, A3, B1, B2, B3) de façon à obtenir une pluralité de distances mesurées à l'au moins une extrémité de dispositif (AP, AP1, AP2, AP3), chaque position d'ancrage (A1, A2, A3, B1, B2, B3) correspondant à une distance mesurée ; et, sur la base d'un algorithme de positionnement, analyser la pluralité de positions d'ancrage (A1, A2, A3, B1, B2, B3) et la pluralité de distances mesurées pour calculer une position d'installation de la ou des extrémités de dispositif (AP, AP1, AP2, AP3) dans la zone intérieure.

(ZH) 一种室内网络通讯设备定位方法用以定位设置于一室内区域的至少一设备端（AP， AP1，AP2，AP3），该方法包含以下步骤：S1通过卫星定位取得一移动终端（1，1A，1B）的一初始位置（A0，B0）；S2根据惯性导航以及初始位置（A0，B0）取得移动终端（1，1A，1B）于室内区域的多个锚点位置（A1，A2，A3，B1，B2，B3）；S3移动终端（1，1A，1B）于该多个锚点位置（A1，A2，A3，B1，B2，B3）量测并取得与至少一设备端（AP， AP1，AP2，AP3）之间的多个量测距离，其中每一锚点位置（A1，A2，A3，B1，B2，B3）对应一量测距离；以及根据一定位算法分析该多个锚点位置（A1，A2，A3，B1，B2，B3）以及该多个量测距离以计算出至少一设备端（AP， AP1，AP2，AP3）于室内区域的一设置位置。
