Abstract

The invention provides an intelligent navigation method for overpass bridges on the basis of RFID. The method includes steps of: 1) acquiring an electronic map, and planning a driving route accordingto preset start and destination; 2) determining the property of the present road, which includes non-overpass roads and overpass roads, and if the present road is a non-overpass road, performing navigation by using GPS positioning signal with combination of the driving route, and if the present road is an overpass road, receiving a radio-frequency signal, which includes the number of a present ramp and is sent by an RFID tag arranged on the overpass bridge, by means of an RF antenna, and performing navigation with the GPS positioning signal, the number of the ramp and the driving route. In theprior art, positioning precision of the GPS positioning signal is about 10 m, so that incorrect navigation even navigation mistake may occur at a place where overpass bridges are concentrated. The method in the invention is used for assisting the GPS positioning signal to perform precise navigation.

Description

technical field [0001] The invention relates to the field of road navigation, in particular to an RFID-based intelligent navigation method for overpasses. Background technique [0002] With the progress of society, people's living standards have been further improved, and the number of cars has also increased rapidly, followed by roads becoming more and more complicated. 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. Car GPS navigation, navigator is a car driving assistance device that can help users accurately locate the current location, calculate the itinerary according to the established 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 locatio...
