Walking light source locator and indoor horizontal walking light source positioning system

Abstract

The invention relates to a walking light source locator, which is fixed on shoes worn by a locating object, and comprises a hanging buckle, a pressure sensing switch and an LED light source emitter. The buckle is used to fix the LED light source transmitter on the back of the shoe, and the pressure sensor switch is arranged under the heel; the emission direction of the LED light source is perpendicular to the ground, and the pressure sensor switch circuit is used to control the working state of the light source transmitter. The present invention also relates to an indoor horizontal walking light source positioning system realized by the locator, comprising an interlayer separated by a transparent floor laid indoors, a walking light source locator fixed on the sole of the positioning object, and a plurality of walking light source locators arranged at the bottom of the interlayer Multi-angle receiving sensing system.

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...

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
