Abstract

The invention discloses a positioning device, a control method of same and a positioning system, which are capable of determining position data of a positioning object obtained by a relative coordinate system and can determine the absolute position of the object at high reliability wihtout manual work. The positioning device, on the basis of time-sequence electric wave intensity data stored in a first storage unit, determines a time that the positioning object is most closed to a base station in correspondance of every base station. The positioning device converts data, which is stored in a second storage unit and acquired by correlating all the times from the first time, most closed to any one base station, to a second time, determined by a determination unit and most closed to another base station, into data in which the position coordinations of an absolute coordination system of the base station, that is most closed to the positioning object at the first time, serve as a base point.

Description

[0001] This application claims priority to the Japanese application with the filing date of July 10, 2017 and application number JP2017-134784, and cites the content of the above-mentioned application, which is incorporated herein by reference in its entirety. technical field

[0002] Embodiments of the present invention relate to a positioning device, a control method, and a positioning system. Background technique

[0003] Currently, there is a system that utilizes a technique called PDR (Pedestrian Dead Reckoning) to locate a location object such as a person or an object, and to generate a moving line of the location object based on the positioning result. PDR is a technology that uses acceleration sensors, gyro sensors (angular velocity sensors), geomagnetic sensors (electronic compass), etc. to measure the moving direction (angle) and moving amount (distance, such as stride) of the positioning object to locate the position of the positioning object.

Embodiment Construction

[0047] Hereinafter, with reference to the accompanying drawings, descriptions of a positioning device and a positioning system capable of positioning (positioning) the absolute position of a positioning target with high reliability without human manipulation based on the position data of the positioning target obtained through a relative coordinate system Examples will be described.

[0048] figure 1 It is an overall configuration diagram of a positioning system 100 according to an embodiment. The positioning system 100 takes people or objects that move freely within a specified positioning area in buildings such as factories, warehouses, offices, etc., or in places where buildings, facilities, etc. A system for locating a location within an area. Such a positioning system 100 includes a plurality of base stations 10 (10A, 10B, 10C, . . . ), a mobile station 20, and a positioning server 30 as a positioning device.

[0049] The plurality of base stations 10 are fixed station...
