Abstract

The invention is applicable to the technical field of positioning, and provides an indoor positioning device. The indoor positioning device comprises a base, a light source, a rotating member, a rotating shell and a controller, wherein the rotating shell is divided into a plurality of coding rings, each coding ring is divided into a plurality of coding bits, an angle of each coding bit is 360/N degrees in the latitudinal direction, and the coding bits of different coding rings are different in configuration mode; a plurality of coding bits of the coding rings are of a light transmitting state, more than two continuous light-proof coding bits do not exist, and a plurality of coding bits, which are configured in a specific mode, form a start bit and a stop bit; each coding ring comprises a special coding bit; and the base is further provided with an optical coupler, the side, which faces to the base, of the rotating member is provided with a light blocking piece, and frequency hopping occurs every time when the rotating member drives the light blocking piece to penetrate through a clamping slot. The indoor positioning device realizes positioning by being combined with light signal sensing of a receiving terminal through the special rotating shell and the hopping light source, the structure is simple, and the positioning method is novel, accurate, good in stability and low in cost, thereby being suitable for indoor high-precision positioning.

Description

technical field [0001] The invention belongs to the technical field of positioning, and in particular relates to an indoor positioning device and a positioning method. Background technique [0002] With the advancement of science and technology and the development of social economy, people's demand for indoor positioning services is increasing day by day. In some public places, such as shopping malls, airports, exhibition halls, office buildings, warehouses, underground parking lots, etc., accurate indoor positioning information can be convenient for users. Shopping, traveling, finding indoor targets, etc.; able to efficiently manage available space and inventory materials; able to navigate police, firefighters, soldiers, and medical staff to complete specific indoor tasks. Smart spaces and ubiquitous computing are inseparable from location-based services, so indoor positioning has broad application prospects. Although GPS can meet the needs of many applications in outdoor ...
