Problems solved by technology

These characteristics make users face many problems in terms of large differences between positioning data and actual walking behavior, and wrong determination of the status of mobile devices.
And for the positioning object, the electromagnetic radiation generated by various modern electrical equipment in the room has brought great challenges to the normal operation of the positioning terminal
Since the electromagnetic radiation interference of electrical equipment and the action state of the positioning object will seriously affect the positioning performance, it is becoming a priority to study how to make full use of incident light to determine the behavior characteristics of walking targets, avoid or reduce interference, and avoid walking positioning delays and errors. This is a big challenge in the design of the positioning system

Embodiment Construction

[0012] Detailed reference is now provided to the practice of the present invention. The following embodiments will be described in order to explain the present invention by referring to the figures.

[0013] In the method proposed by the present invention, based on the beam transceiver system of the white light LED, an indoor interlayer separated by a transparent floor is established, and a multi-angle receiving and sensing system is installed at the bottom of the interlayer, and a buckle is provided on the outside of the heel worn by the positioning object. The center of the center is vertically irradiated downwards and the range of the irradiation angle is fixed. Based on the establishment of different incident angles and different photoelectric energies formed by the same LED light source on multiple receivers, the basic model of data acquisition is established, and the data acquisition is carried out at the convergence center connecting all receivers. Through comparative a...

Abstract

The invention relates to a walking light source positioner. The positioner is fixed to shoes worn by a positioning object and comprises a hanging buckle, a pressure sensing switch and an LED light source emitter. The hanging buckle is used to fix the LED light source emitter to a rear end of the shoes, and the pressure sensing switch is arranged below a heel. An emission direction of an LED lightsource is vertical to ground, and a pressure sensing switch circuit is used to control a working state of the light source emitter. The invention simultaneously relates to an indoor horizontal walkinglight source positioning system which is realized through using the positioner. The system comprises an interlayer which is separated by a transparent floor and is laid indoors, the walking light source positioner fixed on a shoe sole of the positioning object, and a plurality of multi-angle receiving sensing systems arranged at a bottom of the interlayer.

Description

technical field [0001] The invention relates to the technical field of visible light communication, in particular to an LED-based indoor horizontal walking light source positioning system. Background technique [0002] With the development and progress of LED light source technology, white LEDs with the advantages of high brightness, low power consumption, and long life have gradually replaced fluorescent lamps and incandescent lamps. Due to the convenient modulation and quick response of white light LED communication, it has obvious advantages compared with infrared, ultraviolet, radio frequency and other methods in terms of harmless radiation, confidentiality and stability. It has become an emerging visible light communication (VLC) method, which is being gradually promoted to Indoor positioning field. The existing LED positioning method can maintain the stability of the channel and has strong operability, but there is no specific model for the tracking and positioning sa...
