Problems solved by technology

[0005] Subway vehicles are already a very common mode of transportation in urban public transportation, but there are still many inconveniences when taking the subway. Unfamiliar places may not be easily accessible through various signs
Moreover, the current mobile phone navigation system needs to rely on GPS. GPS positioning is very inaccurate when in the subway, and it cannot well realize the navigation inside the subway network.

Embodiment 1

[0078] Please refer to figure 1 and figure 2 , Embodiment 1 of the present invention is:

[0079] Such as figure 1 The shown method for realizing vehicle positioning and navigation by using visible light communication includes the following steps:

[0080] S1. The lighting terminal receives the current vehicle location information sent by the passenger information server. The passenger information server can obtain the location information of each vehicle in real time.

[0081] S2. Encode the location information. Specifically, the location information is encoded by the controller at the lighting end.

[0082] S3. Send the encoded position information to the driving power supply at the lighting end.

[0083] S4. The driving power source controls the LED lamp at the lighting end to transmit a LiFi signal to the client end, and the LiFi signal includes encoded position information. Specifically, the transmission of LiFi signals is realized through the rapid on-off of LED...

Embodiment 2

[0094] Please refer to image 3 , the second embodiment of the present invention is:

[0095] A system for realizing vehicle positioning and navigation by using visible light wireless communication, comprising:

[0096] passenger information server 1;

[0097] The lighting terminal 4 includes a first processor 5, a first memory 6, and a first computer program stored on the first memory 6 and operable on the first processor 5,

[0098] A client 7 comprising a second processor 8, a second memory 9 and a second computer program stored on the second memory 9 and operable on the second processor 8,

[0099] When the first processor 5 executes the first computer program, the following steps are implemented:

[0100] Receive the current vehicle position information that passenger information server 1 sends;

[0101] encoding the location information;

[0102] Send the encoded position information to the driving power supply of the lighting terminal 4;

[0103] The driving power...

Abstract

The invention discloses a method and system for realizing vehicle positioning and navigation by using visible light wireless communication. The method includes: receiving the current vehicle position information sent by the passenger information server at the lighting terminal; encoding the position information; The information is sent to the driving power supply at the lighting end; the driving power supply controls the LED lamps at the lighting end to transmit a LiFi signal to the client, and the LiFi signal includes encoded position information; the client decodes the received LiFi signal to obtain the current vehicle's location information. Positioning and navigation can be realized without using GPS, which is easy to use. The present invention makes full use of the existing equipment to obtain position information, has low cost, is easy to implement, and is suitable for positioning and navigation of subway vehicles.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and system for realizing vehicle positioning and navigation by using visible light wireless communication. Background technique [0002] LiFi (Light Fidelity), short for visible light wireless communication, is a new wireless transmission technology that uses the visible light spectrum (such as the light emitted by a light bulb) for data transmission. LiFi uses already laid equipment (ubiquitous LED lamps) to form a device similar to an AP (WiFi hotspot) by implanting a tiny chip on the light bulb, so that the terminal can access the network at any time. This technology transmits data by changing the flickering frequency of room lighting. As long as the lights are turned on indoors, the Internet can be accessed without WiFi. [0003] On October 15, 2013, the School of Information, Fudan University successfully realized network signal transmission using visible li...
