Description
Technical field
The present invention relates to the attachment device of vehicle, exactly is the guider of a kind of vehicle self-navigation, location.
Background technology
The application product of existing GPS global satellite positioning, as the autonomous type satellite navigation system, mostly be to add that with existing standard industry computing machine the gps satellite signal receiver combines, system's occupation space is bulky, and design of the power supply of industrial computer and electrical specification, be to be design standards,, influence the normal operation of other electronic equipment on the vehicle easily so can't meet the demand of vehicle environment for use fully with the industrial machinery environment for use.The GPS Global Positioning System (GPS), be to see through 24 artificial satellites of empty 6 orbital motions on earth, round-the-clock emission constantly location signal, gps receiver is at the satellite signals that receive more than 3, just can calculate the longitude and latitude of position, highly, speed, data such as direct of travel, at the initial stage that the GPS Global Positioning System (GPS) is enabled, the U.S. adds the artificial interference signal for military factors, therefore there is the error amount of 50-150 rice to exist, in recent years after the U.S. has removed artificial interference signal painstakingly, present error amount has been to dwindle greatly just, but it is bad as rainy weather cloud layer thickening to work as weather, free number of electrons increases in the cloud layer, can produce interference to satellite signals, or because of the influence of terrain and its features such as high buildings and large mansions reflection wave, the location longitude and latitude error amount that gps receiver calculates has sizable change, the navigation operations Control Software needs double counting displayed map picture, cause the counting yield variation of navigation operations Control Software, miscount perhaps appears, if enter the tunnel, signal is covered during tube, can't receive the signal of gps satellite positioning system especially, need wait until and leave the tunnel, could receive the signal of gps satellite during tube once again, so the map s operation control software of navigational system can be the state that is in stagnation for some time.
For remedying the geneogenous deficiency of gps satellite positioning system, the device that can add similar inertial navigation, but estimate the vehicle course as electronic gyroscope secondary navigation system calculation procedure, electronic gyroscope needs the speed of a motor vehicle signal with reference to vehicle, just can calculate the direct of travel and the travel distance that estimate, if the speed of a motor vehicle signal of vehicle has error to exist, then electronic gyroscope not only can be calculated the generation error, and this error is to exist in the mode that adds up, can cause the time of use more of a specified duration, error will be more and more big.
In the application of Japanese navigational system, in order to revise the error of GPS position location satellite signal, place in a known accurate latitude and longitude coordinates is provided with base station, after base station receives GPS position location satellite signal, calculate the error amount of GPS position location satellite signal, again the error amount data is converted to the form of DGPS difference location, and Japan is in order to reach the effect of ITS Intelligent Transportation System, utilize the inductive coil of being buried under the road, collect the data of vehicle flow rate on the road, after the arrangement of the capable control of road center, see through frequency modulated subcarrier broadcast system and isomorphism type device, with DGPS difference navigation data and Real-time Road information, the navigational system that sends in travelling receives, in order to allow the navigational system user learn where road is to belong to be jammed, situations such as sealing.
Yet above-mentioned automobile satellite navigation system is to rely on satellite merely to locate, navigation, though satellite transmission signal is occupied special frequency range, in today of radio communication prosperity, interference between the wireless frequency is inevitable, this will inevitably bring error to navigational system, add the error in the transmission course of satellite own, generally can only determine general orientation according to satellite navigation system, the orientation is difficult to judge accurately, especially in the zone of transportation network than comparatively dense, this error will be brought very big inconvenience, simultaneously, only rely on satellite in the navigational system, lack necessary geography, transit information, even the driver has judged the position at own place, still can't the clear and definite approach that next step travels.
