Description
Technical field
The present invention relates to navigator fix field, especially a kind of viaduct intelligent navigation device and navigation system based on RFID
System.
Background technology
With the development of the society, people's living standard further improves, the quantity of automobile also surges rapidly, the thing followed
It is the more sophisticated of road.This virtually brings great inconvenience to the traveling of vehicle, and GPS vehicle mounted guidances also just turn into therewith
The essential instrument of car owners.Car borne GPS navigation, navigator exactly can help user to be accurately positioned current location, and
And stroke is calculated according to set destination, user's row is guided to destination by map denotation and voice message two ways
Car steering auxiliary equipment.For user on vehicle mounted GPS guidance system after any 2 points of mark, navigation system will be automatically according to
Current position, best route is designed for car owner.In addition, it also have change function, if user because imprudence miss crossing,
The optimum line of vehicle mounted GPS guidance system recommendation, more than 200 meters of vehicle location off-target tracks, vehicle GPS are not walked
Navigation system can design one for user again and return to main shipping track route, or set for user according to the new position residing for vehicle
Count an optimum line from property position to terminal.
It is such as more if running into more intensive viaduct but the precision of GPS location signal is generally in 10m-20m or so
Individual viaduct arranged side by side or overlapped viaduct, because its is closer to the distance, the judgement of presently described ring road can be lost
By mistake, occur so as to which the situation of the inaccurate even navigational error of navigation will occur.
The content of the invention
The present invention provides a kind of viaduct intelligent navigation device based on RFID, it is intended to overcomes existing GPS navigation equipment to exist
Navigated on viaduct inaccurate present situation.
