Description
Technical field
The utility model relates to a kind of street lamp auxiliary positioning wireless device, belongs to city vehicle airmanship.
Background technology
Existing Vehicular navigation system is generally all equipped with GPS, can obtain the navigation information such as longitude, latitude, height of vehicle in real time, and shown by numerical map by receiving gps satellite signal.But along with inside city, tall buildings exit, excessively tunnel, mountain and overpass get more and more, and often run into the situation that gps satellite signal is blocked, is difficult to provide effective locating information when vehicle travels on road.Consider above-mentioned situation, often on the basis of GPS location, pass through the mode assisting vehicle navigator fix such as dead reckoning (Dead Reckoning, DR), map match (Map Matching, MM).
Document (Jin Liangliang, He Wentao, Xu Jianhua, etc., " a kind of Low-cost GPS/DR Design of Integrated Navigation System ", " computer engineering ", in September, 2012, the 38th volume, 18th phase, 228th ~ 230 pages) provide a kind of DR method based on single gyro instrument list accelerometer, and form vehicle GPS/DR integrated navigation system in conjunction with GPS, location can be kept when gps signal blocks.
Document (Wu Zhoujie, " vehicle's composite navigation system research ", Shanghai Communications University's master thesis, 2009) provide a kind of combined type automotive positioning method based on inertial navigation/GPS/ electronic compass, vehicle location precision can be improved by the mode of Multi-information acquisition, the positioning precision in a period of time can be ensured when GPS lost efficacy.
Can when GPS lost efficacy for vehicle provides navigation information by the mode of integrated navigation.But DR navigate mode exists the error characteristics of accumulating in time, make DR only can ensure short-term positioning precision, if do not receive gps signal for a long time, just cannot realize the navigator fix of vehicle;
Grant number is provide a kind of city vehicle locating guidepost sensor in the utility model patent of ZL2005200771759.5, by laying the mode of road sign in the road, provides positional information to vehicle.Current rout marking allocation needs in city, arrange road sign point, and will obtain the full location information of road sign, needs longer communication time, if Vehicle Speed is talked about faster, is often difficult to location.
Utility model content
Goal of the invention: in order to overcome the deficiencies in the prior art, the utility model provides a kind of street lamp auxiliary positioning wireless device, consider that a fairly large number of illuminating street lamp has been installed in urban road both sides, and street lamp distribution is closeer, geographic position remains unchanged substantially, the utility model is using street lamp as reference road sign, and wireless device formation beacon is installed on street lamp, in order to assistant GPS, integrated positioning is carried out to vehicle, realize automatic navigator in city scope and still can provide high precision position information when gps satellite signal is blocked for a long time, effectively a kind of, inexpensive scheme.
Technical scheme: for achieving the above object, the technical solution adopted in the utility model is:
A kind of street lamp auxiliary positioning wireless device, comprise the communication chip of housing and transmission street lamp ID numbering, described communication chip is arranged in housing.
Described street lamp ID numbers and street lamp one_to_one corresponding, street lamp ID numbers and street lamp geographic position one_to_one corresponding, obtain the geographic position that street lamp ID numbering can know street lamp, after onboard system obtains street lamp ID numbering, based on street lamp ID number with the database of street lamp geographic position corresponding relation after can know street lamp position, relation between set vehicle and street lamp, can carry out position correction to automatic navigator, and then realizes navigation.
Preferably, also comprise input equipment, described input equipment is numbered for inputting street lamp ID, and described input equipment is also arranged in housing.
Preferably, described street lamp ID numbering is solidificated in communication chip.
Preferably, chip identification code is solidified with in described communication chip.Carry navigational system by chip identification code identification wireless signal: if there is chip identification code in wireless signal, then carry out subsequent operation; Otherwise, abandon this wireless signal.By the setting of chip identification code, also avoid carrying navigational system to the process of garbage signal, increase location consuming time.
Preferably, also comprise solar cell, wherein the plane skylight of solar cell is outside exposed as the part of housing, and the remainder of solar cell is arranged in housing, is that wireless device is powered by solar cell.
Preferably, described communication chip is Bluetooth chip.
Beneficial effect: the street lamp auxiliary positioning wireless device that the utility model provides, street lamp ID can be gone out number by wireless transmission, using city street lamp as navigator fix reference road sign, the positional precision of onboard navigation system can be improved largely, even if satellite navigation signals is blocked and also can accurately locates on the road of tunnel, both sides tall buildings exit; And the utility model equipment only need install wireless device additional on the basis of existing urban transportation device, and repacking amount is little; The utility model mainly provides the ID of street lamp to number when Signal transmissions in addition, and amount of communication data is little, consuming time short, also applicable when Vehicle Speed is very fast.
