Description
Technical field
The present invention relates to utilize in a kind of automobile no-stop charging system induction field medium and low frequency magnetic field, low-frequency electromagnetic wave near region to carry out information interactive method.This is a kind of no-stop charging system design and implementation method that possesses high communication reliability, good information confidentiality and outstanding economy.The no-stop charging system that content of the present invention can be widely used in locating in road, parking lot etc. designs.
Background technology
Along with vehicle population increases fast, various public ways and means of transportation load also are sustainable growth trend, jam often takes place, and it is very outstanding especially especially to gather around the resistance problem near common road toll station, expressway access, outlet toll station.Toll station charge operating efficiency is not high to be to gather around resistance, immediate cause that the vehicle percent of pass is low near causing.Though control of traffic and road department also attempts to simplify, accelerate the charge settlement process by multiple measure, lengthy process for example by using traffic IC card, using bank card to avoid cash settlement to cause, even take to receive free clearance of card and improve percent of pass, but these measures low percent of pass problem that " stopping, hand over card, clearing, clearance " causes all can't fundamentally solve vehicle by toll station the time.Be subjected to the restriction of economic factors and highway administration requirement, future for a long time in the highway toll website can not cancel all, what will overcome so that toll station causes gathers around the resistance bottleneck problem, one of effective technology means are exactly to adopt no-stop charging system.Worldwide, based on different technical foundation some multi-form no-stop charging systems have been proposed, for example based on GPS (GPS), based on roadside distribution microwave emission website, based on integrated IC-card or the like, but these systems really do not come into operation mostly, and reason just is that its economy, reliability and information privacy often can't take into account.When for example vehicle uses traffic IC card or bank card to settle accounts automatically then the confidentiality of said system on principle, just can't meet the demands, reason is to use between the toll station fixed terminal and vehicle mobile terminals in the said system high frequency and even microwave communication mode to carry out information interaction, Content of communciation is easy to be intercepted or is disturbed, and the high frequency transceiver is relatively costly, though use exactly because above-mentioned reason similar system has had in European expressway tol lcollection among a small circle, also do not popularize.Realize non-parking charge, speed of related movement requirement (being typically greater than 10m/s) is just arranged between vehicle mobile terminals and toll station fixed terminal, and the IC-card automatic fee mode of working load modulation technique (IC-card as self-service ticketing public transport or subway import and export gate is paid the fees) also can't realize the data reliable interaction so.The purpose of this patent is exactly to propose a kind of technological means that can take into account economy, reliability and confidentiality requirement, promote really popularization and application on a large scale of no-stop charging system, effectively solve road toll website and other public transit facility toll stations and gather around the resistance problem because of the low vehicle that causes of charge operating efficiency.
Realize the non-parking charge operation, carry out the information transmission selection that is inevitable by wireless mode, they all use high frequency and even microwave signal to carry out relative motion between all or part of information transmission and fixed terminal and portable terminal exactly but cause said system to use a poor key reason of economy, reliability and confidentiality.Solve above-mentioned contradiction, also need from analyzing electromagnetic wave spatial transmission characteristic.Principle of work according to electromagnetic field, but the electromagnetic wave separated into two parts from the emissive source to the surrounding space: a part is that near the emissive source near region induction field is (from emissive source apart from r＜λ/2 π, λ-electromagnetic wavelength), electromagnetic energy wherein is to external radiation, but comes and goes exchange by the space between emissive source and induction field; Another part is the far region radiation field (from emissive source apart from r＞λ/2 π) beyond the induction field, and the electromagnetic energy of radiation field radiate fully.In induction field, the distribution of prevailing electric field intensity or magnetic field intensity is with the variable in distance highly significant, according to 1/r
3The rule decay of (60dB/10 is distance doubly) then is that promptly the electromagnetic intensity decay is wanted significantly more than the far zone field near field according to the rule decay of 1/r (20dB/10 is distance doubly) in the far zone field.According to antenna theory, the electrical length l/ λ of electromagnetic wave emitting antenna is more little, and its far zone field radianting capacity is poor more; Determine under the condition in the emitting antenna size, use low frequency (big wavelength) wireless signal transfer information just can effectively reduce the far zone field radiation.Simultaneously,, also can be controlled at (for example within 1 meter) in the very little scope to effective receiving range in the near field, so also can further reduce the far zone field radiation by reducing emissive power in conjunction with the quick attenuation characteristic of near field field intensity (60dB/10 is distance doubly).From the information privacy angle, require the far zone field radiation intensity should be as much as possible little, make to have conventional receiving sensitivity (radio receiver typically-120dBm) can't effectively receive signal outside toll station controllable distance (typically 100m).Since require far-field signal intensity faint to receiving, and it is mutual to finish under the mobile status authentic communication between the vehicle and toll station, can do you so just consider that the inherent characteristic use electromagnetic wave near field that utilize automobile and road surface to press close to transmits information? in addition, vehicle pass-through speed is a key index in no-stop charging system, if use the near region induction field to carry out the information transmission reliably, message data rate and vehicle pass-through speed also are a pair of contradiction that needs solution.Purpose of the present invention is exactly to propose system design and the implementation method that a cover utilizes near region induction field effective transmission information between website fixed terminal and vehicle mobile terminals fully.
