The present invention relates to traffic field of locating technology, pass through the geographical ID optical launchers being placed in above road, the geographical ID optical receivers being installed on vehicle, geographical ID optical receivers include micro treatment module, optical receiver module, map datum module, OBD modules, satellite navigation module composition；The geographical ID optical launchers include optical module, and a kind of geographical ID generation modules composition, decoded by light beam obtains information as the pinpoint method of vehicle and its device.
Description
Technical field
The present invention relates to the navigation locating methods of mobile vehicle, and decoding acquisition information by light beam more particularly to one kind is
The pinpoint method of vehicle and its device.
Background technology
Bus location technology common now is satellite navigation and positioning mostly, and the poor error of positioning accuracy is generally on 10 meters of left sides
The right side can be expanded to 30 meters in case of weather conditions are bad or surrounding has excessive skyscraper to block error.Use Differential positioning
Positioning accuracy is increased to track grade even meter level level in technical know-how, but thus needs to set at a certain distance by road
A positioning reference station is set, and the moment is wanted to keep the wireless telecommunications between base station and user's vehicle, cost is higher and positioning accurate
Degree still only has meter level.If Centimeter Level can be reached using carrier phase differential positioning technology acuracy, but this need to relatively hold high again
Expensive user terminal vehicle positioning equipment, and carrier phase observation data initialization time would generally tens seconds to more than ten minutes it
Between be usually five or six minutes, vehicle once during traveling satellite positioning signal by skyscraper, trees, tunnel, bridge
Influence and interrupt, it is long to reinitialize process time.More also possess skilled antenna without base station track class precision
Mobile satellite location equipment, but price is equally excessively high.To sum up, although satellite positioning tech is very universal, precision when at low cost
Not high, cost is again excessively high when precision is high, and have base station also wants the moment to keep the wireless telecommunications with mobile vehicle, and vertical
Satellite-signal can be lost by handing under bridge or in tunnel, and atrocious weather and electromagnetic environment can also interfere satellite-signal, simultaneously
It is threatened by portable Gps shielding devices.
Invention content
It is an object of the invention to overcome the shortcomings of existing vehicle positioning technology, provide a kind of positioning accuracy is high, cost compared with
Low vehicle positioning technology.
The present invention solves its technical problem and following technical scheme is taken to realize.
A kind of method and its device of vehicle location include the geographical ID optical launchers being placed in above road（100）,
