Abstract

The invention discloses an LIFI (light fidelity)-based intelligent navigation method comprising steps of acquiring an electronic map, and planning a route in accordance with a point of departure and adestination arranged before; judging an attribute of a present road, wherein the attribute of the road comprises a non-tunnel road and a tunnel road; when the present road is judged as the non-tunnelroad, using a GPS (global position system) satellite signal with the route for navigation; when the present road is judged as the tunnel road, receiving a flicker frequency that is sent by an LED lamp arranged in a tunnel and has a present location signal, wherein the location signal is a GPS analog signal of a location where the LED lamp is positioned; coverting the flicker frequency back to theGPS analog signal; and using the GPS analog signal with the route for navigation. With the help of the LIFI-based intelligent navigation method, accurate navigation of a vehicle can be implemented inthe tunnel in absence of a GPS signal, through the GPS analog signal.

Description

technical field [0001] The invention relates to the field of tunnel navigation, in particular to a LIFI-based intelligent navigation method. Background technique [0002] With the progress of society, people's living standards are further improved, and the number of cars is also increasing rapidly, followed by more and more complicated roads. This has virtually brought great inconvenience to the driving of the vehicle, and GPS vehicle navigation has also become an indispensable tool for car owners. Vehicle-mounted GPS navigation, a navigator is a car driving assistance device that can help users accurately locate the current location, calculate the itinerary according to a predetermined destination, and guide the user to the destination through map display and voice prompts. After the user marks two points arbitrarily on the car GPS navigation system, the navigation system will automatically design the best route for the car owner based on the current location. In addition...
