Embodiment Construction

[0037] In order to make the objectives, technical solutions, and advantages of the present invention clearer and more comprehensible, the present invention will be further described in detail below in conjunction with illustrative embodiments and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0038] The system and method for detecting and guiding idle parking spaces in indoor parking lots based on optical communication provided by the present invention are implemented based on LED lighting sources. As a new type of energy-saving, non-radiation green lighting source, LED light source has become the preferred light source for lighting engineering design, upgrade and transformation. As incandescent lamps gradually withdraw from the market, LED light sources have higher energy efficiency than energy-saving lamps. It has become the main...

Abstract

The invention discloses an indoor parking lot guide method and system based on visible light communication. The system comprises a light source infrastructure which is used for installing a modulating coding LED illumination light source in advance, wherein LED light source coding is correspondingly correlated with the installation position; a parking space detection system which detects the idle states of the parking spaces in real time through an indoor illumination LED light source; a positioning system which is used for determines the parking position of a vehicle and the position of a person through the LED light source coding; and a guide system which achieves the guide of the person according to the parking position of the vehicle and the position of the person. According to the invention, the method and system solves problems that a conventional large-scale parking lot cannot achieve the positioning of an indoor person, a large number of pieces of additional detection equipment are needed for the parking space detection and guide and a construction project is more complex and is higher in cost. The method and system achieve the integration of energy-saving illumination, parking space detection, vehicle searching, and guide.

Description

Technical field [0001] The invention relates to the field of free parking space detection and indoor positioning and guidance, in particular to a system and method for detecting and guiding the free parking space of an indoor parking lot based on LED lighting communication. Background technique [0002] With the upgrading of the automobile consumer market, more and more cars are owned. In order to solve the common social problem of "difficult parking", parking lots have been built more and more, and the "difficult parking" has been partially alleviated. The building is too huge, and finding a car after parking has become another problem. For the purpose of saving time and improving efficiency, the society has an increasing demand for energy-saving and intelligent parking systems. At present, some technical solutions for free parking space detection and reverse car searching have entered the commercial application stage. [0003] Common parking space detection technologies mainly ...
