Abstract

The invention, which relates to the field of indoor positioning, discloses a BLS-based indoor positioning system and positioning method. The system comprises a management terminal and a client. The management terminal is used for receiving location positioning of the client and monitoring the client in real time. A mark point display module is arranged at a connecting terminal of the management terminal. According to the invention, a positioning tag is bound by the client and personal information is authenticated. A first positioning system and a second positioning system cooperate with each other to obtain indoor positioning of the client; coarse positioning is realized in first two-dimensional coordinate space; a positioning tag position is displayed in real time at the mark point display module; and remote management of data is realized. A distance from the client to a phase ranging module as well as a height angle and horizontal angle from an orientation detection module to the client is obtained through measurement and calculation; and a distance L from the client to a second two-dimensional coordinate original point is calculated, so that precise coordinate positioning is realized and the precise value of indoor positioning is improved.

Description

technical field [0001] The present invention relates to the field of indoor positioning, and more specifically, the present invention relates to a positioning system and positioning method that can be used indoors based on BLS. Background technique [0002] With the popularity of the Internet of Things and mobile devices, positioning technology is applied in more and more scenarios. However, satellite positioning systems cannot provide satisfactory positioning services in indoor environments. At present, the positioning technologies mainly used in the indoor positioning system include Bluetooth, Wi-Fi, ultrasonic and so on. Existing technologies have their own advantages and disadvantages in terms of deployment cost, positioning accuracy, convenience and stability, and there is no such dominant technology as the outdoor satellite positioning system. [0003] The Chinese patent application publication number CN 104535962 A discloses an indoor positioning method and an indoo...
