Specifically, RFID devices, such as IC cards, may be installed in cross road, road bed or other proper positions the vehicle will pass by; and RF inducing transceiving device may be installed inside vehicle to read the information of the RFID mark in the cross road or other position to realize the locating navigation of motor vehicle via matching with electronic map. Compared with GPS navigation technology, the present invention is simple and low in cost.
Description
Technical field
The invention belongs to location navigation disposal system field, be specifically related to a kind of disposal system technology of utilizing RF identification (RFID) technology to realize the power actuated vehicle location navigation.
Background technology
Development along with integrated circuit technique, the particularly development of contactless ic technology, utilize RF identification (RFID) technology to come important item is discerned very ripe at present, RF identification (RFID) sign is installed in the article that need identification, by corresponding check implement, just can discern this article easily.RF identification (RFID) technology also has multiple application in addition, the automatic toll collection that do not stop of express highway, rail vehicles recognition and tracking, freight container recognition and tracking, come in and go out entrance guard management, animal identification, tracking or the like.But still there is not the Position Fixing Navigation System that RF identification utilized (RFID) technology realizes power actuated vehicle at present.
What the location and navigation technology of current mobility vehicle was the most frequently used is global location (GPS) system.Gps system is that 20,000 kilometers satellite is formed by 24 height, they can provide high accuracy three-dimensional position, three-dimensional velocity and the precise time information of global range from arbitrary carrier between kilometer high-altitude, ground to 9000 with 6 different orbit operations.Can receive positioning signal as long as be installed in board units on the vehicle, just can make warp, Position Latitude and the temporal information of this car, cooperate electronic chart just can realize the navigation of power actuated vehicle from three satellites.
The satellite-signal of GPS receiver to receiving decoded or adopted other technology, after the information on the carrier wave of being modulated at is removed, and just can the reinsertion of carrier.Strict, carrier phase should be called as carrier wave beat frequency phase place, and it is that the satellite signal carrier phase place and the receiver local oscillation that influenced by Doppler frequency shift of receiving produce the poor of signal phase.Generally measure constantly in the epoch that the receiver clock is determined, maintenance is to the tracking of satellite-signal, just can note the changing value of phase place, but the phase place initial value of receiver when beginning to observe and satellite oscillator is ignorant, the phase place integer of initial epoch also is ignorant, be integer ambiguity, can only be as parameter calculation in data handing.The precision of phase observations value is high to millimeter, but prerequisite is to solve integer ambiguity, therefore only could use the phase observations value at relative positioning and when one section continuous measurements is arranged, and also can only adopt the phase observations value and will reach the accuracy of positioning that is better than meter level.
But gps system satellite-signal such as between indoor or the main housing-group in urban district is accepted bad its performance of area and availability and is all shown sharp and descend; Its locating speed is also relatively slow, is implementing to dispose also relatively costliness.Although obtained significant improvement in that GPS is technical recently, these problems still appreciable impact cost, availability and the performance of solution.
Though gps system can more accurate solution vehicle location and navigation problem, its maximum shortcoming is technical sophistication and cost height.
Summary of the invention
The objective of the invention is to propose a kind of location navigation that promptly utilizes RF identification (RFID) technology to reach power actuated vehicle cheaply.Thereby can solve present RF identification (RFID) and can only solve article identification and non real-time automatic tracking and the technical sophistication cost high problem of gps system in location technology.
Groundwork of the present invention is: RFID (Radio Frequency Identification) RF identification is a kind of contactless automatic identification technology, it is by the automatic recognition objective object of radiofrequency signal and obtain related data, identification work need not manual intervention, can work in various harsies environment.The RFID technology can be discerned high-speed moving object and can discern a plurality of labels simultaneously, and is swift and convenient to operate.
The short-range radio frequency product is not afraid of rugged environments such as oil stain, contamination by dust, can substitute bar code in such environment, for example is used on the conveyor line of factory and follows the tracks of object.Length is used in the traffic apart from radio frequency products more, and decipherment distance can reach tens meters.
RF identification (RFID) is generally noncontact mode integrated circuit (IC) card, its cooresponding card reader goes out the radiofrequency signal of certain frequency by the antenna transmission of configuration, produce magnetic field, when the article that noncontact mode integrated circuit (IC) card is installed enter efficient range, noncontact mode integrated circuit (IC) thus the lead winding in the card produces inducing current obtains energy, and can send out information such as self coding according to the instruction of card reader, read back decoding by card reader and handle through data processing equipment, be sent to the dispatching and monitoring center by wireless channel or wire message way, according to being installed in the location and time information that the card reader of each article through the position reads, just can determine the present residing position of article.
The power actuated vehicle Position Fixing Navigation System that the present invention proposes, it is characterized in that, this system is made up of the data collection process device (3) of the RF receiving/transmission device that is installed in vehicle (2), connecting device (2), the radio frequency identification marker that has geographic position, road and other relevant informations (1) of correct position that is placed on each crossing, road, roadbed or other vehicle processes of vehicle process, read the cooresponding information of radio frequency identification marker (1) at each crossing, road by transmit receive unit (2) by wireless radio frequency mode, cooperate electronic chart just can realize the power actuated vehicle location navigation.
