Abstract

The invention discloses a positioning beam transmitting system, a positioning beam transmitting method and an indoor positioning system. A positioning space includes multiple sub positioning spaces. Multiple positioning beam transmitting devices are respectively fixed to predetermined positions in the multiple sub positioning spaces, and are divided into at least two transmitting device groups. A controller is connected with the multiple positioning beam transmitting devices, and is used for making the multiple positioning beam transmitting devices switch the working state thereof in a predetermined period. The predetermined period includes at least two sub periods which respectively correspond to the at least two transmitting device groups. The positioning beam transmitting devices in each transmitting device group work in the corresponding sub period, and do not work in the other sub periods. According to the invention, the generation of a laser overlap region is avoided during expansion of the positioning space, so that the problem of inaccurate positioning caused by a laser overlap region is solved.

Description

technical field

[0001] The invention relates to the field of positioning, in particular to a positioning beam emitting system, method and indoor positioning system. Background technique

[0002] As an auxiliary positioning of satellite positioning, indoor positioning technology can solve the problem that satellite signals are weak when they reach the ground and cannot penetrate buildings.

[0003] Laser positioning technology is a common indoor positioning technology. The solution is to build a positioning light tower emitting laser in the positioning space, scan the positioning space with laser, design multiple laser receiving sensors on the positioned object, and The receiving end performs arithmetic processing on the data, and directly outputs the three-dimensional position coordinate information. Its positioning process can be performed by figure 1 shown.

[0004] Due to the limited scanning area of ​​the laser, the space that can be positioned is limited by the range...

Embodiment Construction

[0072] Preferred embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although preferred embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0073] As mentioned above, in view of the problem that laser overlapping areas are prone to appear when the positioning space is expanded, thereby causing interference to positioning, the present invention proposes a new positioning scheme, so that based on the positioning scheme of the present invention, when the positioning space is expanded, , you can try to avoid the phenomenon of laser overlapping areas. Briefly, the positioning soluti...
