Description
Technical field
The present invention relates to micro power radio communication, vehicle location tracking technique and non-stopping toll administration.
Background technology
Existing vehicle location is followed the tracks of, and what generally adopt is the GPS positioning and tracing method; The management of existing highway charge, general what adopt is to provide IC-card or the magnetic card that record has the import address information in inflow point, the information in the import place of reading in the card in the exit again to be write down, thereby the method for chargeing; In addition, also adopted the far Distance RFID system to remember the way of expense automatically in indivedual places.
The problem of GPS positioning and tracing method and existence thereof:
The vehicle that is positioned and follows the tracks of, by being installed in the GPS receiving terminal on this car, receive the positioning signal of four (at least three) gps satellite emissions simultaneously, calculate residing longitude and latitude of this vehicle and height coordinate (X, Y, Z), again in conjunction with electronic chart, with this X, Y, Z location coordinate information, be converted to the geographical location information that we are familiar with, street name for example, concrete reference location etc. are when following the tracks of vehicle location, also need calculating positional information, by existing mobile communications network, pass to control center, could really arrive the purpose that follow the tracks of the location.Say that simply with regard to vehicle location was followed the tracks of, the GPS positioning system at least need be by gps satellite, GPS receiver, mobile communications network, mobile communication terminal (GMS or CDMA transceiver module) and control center.The shortcoming of GPS locating and tracking system (comprises mobile network's usage charges) except construction cost and operation cost height, its use also is subjected to great restriction in the city.Because use one of important prerequisite of GPS equipment, be that the direct projection path is arranged between receiver and the satellite, and gps signal exist signal to receive the blind area at buildings intensive city and interior of building.The GPS location also will be subjected to the influence of multipath effect and many other factors in addition, comprises that long grade of initial alignment signal capture time (is generally 0.5～15min).Field experiment shows, in built-up city, the public transit vehicle of GPS receiver is installed, and the probability that can normally receive the GPS positioning signal is approximately about 70%.At some special occasions,, even can not receive gps signal fully as in the concrete steel building, in basement or the mine.
The problem of IC-card and magnetic card charging method and existence thereof:
We are very familiar for IC-card and magnetic card Fare Collection System, and they all are by the close contact (generally several centimetre within) of card with card reader, reach the purpose of exchange message.Their problem is:
1. because they can only differentiate the import and the exit position of vehicle, and route and mileage that can not registration of vehicle actual travel on turn pike, thereby, in many places, the mileage that will occur charging is significantly smaller than the fee evasion phenomenon of actual mileage, particularly forms the place of networks at many turn pikes.
2. because whom domestic many highways adopt invest whose benefited mode, thereby the situation of a plurality of charge stations often appears in turn pike, not only increased personal management, the expense that charge station builds, and greatly reduce the passage rate of turn pike, influence the service efficiency of turn pike, brought many inconvenience also for simultaneously current vehicle.
3. can not realize non-parking charge.
The problem of far Distance RFID automatic fare collection system and existence thereof:
The method of work of rfid system is by rfid interrogator, and reading and writing device antenna is launched, and discerns through the radiofrequency signal that rfid card reflection or coupling are returned, and communicates.To rfid card, it is a kind of passive communication mode fully, and this mode needs a volume big, trouble is installed, expensive reading and writing device system.When being used for vehicle tracking, the problem of system is:
1. domestic existing far Distance RFID system generally adopts import equipment, and critical piece is import at least, system price height not only, and reading system is huge and trouble is installed; In addition, not only there is the legitimacy problem in employed 900,000,000 frequencies of these systems, and, also can disturb sometimes with existing mobile phone signal.
2. because the communication mode of RFID is a passive type, the raising of communication distance is difficulty very, thereby, often can only adopt the way that increases antenna emissive power and gain, this just requires the installation site of vehicle-mounted rfid card, be equipped with good coupling with the installation position of the reading and writing device antenna of fixing, this just makes the use of far Distance RFID system have very big limitation.For example, require garage's passage very narrow, running speed is very low, and also there is certain problem in the passing through of oversize vehicle, thereby, generally the needing of incompatibility turn pike, particularly highway.
3. the communication mode owing to rfid system is a passive type, thereby the read write line of FID system must receive the aerial signal that reflects through vehicle-mounted rfid card, and just calculation is finished a rfid card identity and read process.Thereby, when a plurality of track, not only need to install a plurality of remote RF ID read-write systems, and be difficult to avoid monkey chatter and phenomenon such as misread.
4. because RFID itself mainly is a kind of identity numbering, the information material that it stores is very limited, and the access of information is also cumbersome.Thereby the very difficult more function that realizes is expanded.
In sum, the major defect of existing GPS positioning and tracing method is: complex structure, and investment is big, and the running cost height can not satisfy the actual needs that vehicle location is followed the tracks of under the urban environment condition of complexity; And have toll road management system now, can't effectively solve the problem of management of the vehicle fee evasion and the block meter rate that do not stop.Based on our company " highway RF car speed monitoring and management system ", 200510021465.6) and " micropower wireless network location system and localization method thereof " (number of patent application: the 200510021087.1) basis of same theme thinking (number of patent application:, promptly by being installed in highway micropower wireless signal transceiver along the line, exchange with the wireless signal between the wireless car plate of passing by of vehicle-mounted micropower, registration of vehicle the position and time of each teleseme of process, realize tracking to vehicle actual travel route; This not only makes the charge of vehicle carry out according to vehicle actual travel mileage, stops the fee evasion phenomenon of turn pike vehicle substantially, and the automatic segmentation of can also realizing not stopping charges.(referring to Fig. 1)
