Bit function etc., but if applying can generate biggish in the positioning scene of outdoor move vehicle because recognition capability is insufficient
Error, so as to cause position inaccurate or generation malfunction etc..
Most widely used in vehicle location detection at this stage is the induction positioning method based on ground induction coil,
It is usually used in parking lot and enters and leaves the fields such as detection, vehicle flowrate and overspeed of vehicle detection.But exist when based on ground induction coil positioning method
When being applied to electric car dynamic radio power supply system position detection, since the applying frequency range of ground induction coil is about
The resonance frequency of 20kHz-170kHz and dynamic radio charging magnetic coupling is very close, if ground induction coil and electrical supply rail
The high-intensity magnetic field that can usually generate because of transmitting coil in electrical supply rail when transmitting coil hypotelorism is caused to detection precision
Severe jamming even is easy to burn out ground induction coil, causes biggish damage to position detecting system.
In conclusion common vehicle location detection mode meeting when being applied in electric car dynamic radio power supply system
Show many drawbacks resolution such as under high velocity environment is low, road pavement penetrability is poor, be easy by electrical supply rail high-intensity magnetic field
Interference etc..Therefore, in conjunction with this project to the total amount of data of electric car dynamic radio power supply system vehicle detection, traffic rate,
The factors such as response speed, design cost, propose a kind of directionality resolution be strong preferably, under high-speed moving state and identification away from
From it is controllable, to the stronger dynamic radio location detection method of electrical supply rail high-intensity magnetic field anti-interference ability, and carried out certain needle
To property design.

Detailed description of the invention
Fig. 1 is control dynamic radio power supply segmented guide rail switching system schematic diagram.
Fig. 2 is vehicle and electrical supply rail relative position and control sequential figure.
Specific embodiment
Below in conjunction with specific embodiment, the utility model is described in detail.
Specific embodiment one:
As shown in Figure 1, the application system of dynamic radio location detection method is mainly by RF transmitter, the onboard day of orientation
The composition such as line, RF Receiving Device, dynamic radio electrical supply rail, relay system, master controller.Wherein RF transmitter, penetrate
Radio circuit designed by cc2500 chip of the frequency receiver by TI company forms, and transmitting terminal radio frequency exit connects position plate
Carry antenna.Transmitting terminal radio-frequency unit and orientation onboard antenna are located at electric car front end and continuous during electric automobile during traveling
It issues 2.4GHz and orients radiofrequency signal.RF Receiving Device is located at each section of front end of dynamic radio electrical supply rail, when vehicle is close

In device.Master controller plays cerebration in the entire system, play radiofrequency signal that RF Receiving Device is received into
Row analysis and arbitration functions, and can control relay system quick response need complete open and shutdown act.
Since the resonance frequency point of 2.4GHz radio-frequency module is much higher than the resonance frequency of dynamic radio electrical supply rail transmitting coil,
Therefore both will not generate interference mutually, thus can to avoid in ground induction coil positioning method since resonance frequency is excessively close
And the electromagnetic interference phenomenon generated.The radio frequency band of 2.4GHz has good penetrability and still has in the scene of high-speed mobile
There is preferable recognition capability, therefore the RF Receiving Device for being embedded in underground can be captured accurately from the radio frequency in move vehicle
The radiofrequency signal that emitter issues.The adjustment of transmission power and reception device receiving sensitivity to RF transmitter, can
The control of radio frequency interaction distance within the scope of certain (about 0.5m-1m), i.e., will be driven into dynamic radio power supply in vehicle
When guide rail, master controller can respond rapidly to so that guide rail works on power.In addition, installing orientation is onboard in RF transmitter
Antenna, the radiofrequency signal for emitting it have preferable directionality ability, so as to avoid sending out with the parallel vehicle of this route
The malfunction that radiofrequency signal out generates the control of this line powering guide rail is interfered.
Specific embodiment two:
As depicted in figs. 1 and 2, the electric car dynamic radio power supply system that the utility model is based on includes radio-frequency transmissions
Device, orientation onboard antenna, RF Receiving Device, dynamic radio electrical supply rail, after electrical switching apparatus, master controller etc. form.
Wherein RF transmitter and orientation pcb board carry antenna and are installed on dynamic radio in the plastic bumper of electric automobile front end,
And the interference that any large-area metal product has prevented its from receiving and dispatching to radiofrequency signal is not installed in bumper as far as possible.Orientation
Ground is directed toward in onboard antenna direction obliquely, by adjusting the transmission power and radio frequency reception of radio circuit in RF transmitter
The receiving sensitivity of device, by the control of radio frequency interaction distance between 0.5m-1m.
RF Receiving Device installing and dynamic radio electrical supply rail front end, and it is embedded in underground together with guide rail, this is just needed
Radio-frequency unit has preferable penetrability for ground.RF Receiving Device is connected with master controller, when vehicle is close to for conductance

And arbitration functions.
Master controller is made of 8 8-digit microcontroller C8051F330-GMR etc., and the microcontroller has decoding and judges function
Can, the principle of arbitration functions is the continuity based on code identification.Radio-frequency transmissions end on electrical supply rail when advancing according to 1ms
Automatic sending cycle carry out the output of continual 20 encoded signals.Due to having carried out the control of transmission power in advance, so that
Receiving end can good progress encoded signal reception in the range of 0.5m-1m, then when radio frequency reception end is not in the range
Complete and continuous encoded signal can not be received.
Therefore, whether master controller receives continuous and complete 20 codings according to radio frequency reception end within a certain period of time
Signal carries out judging whether to guide rail switching.Believe when complete and continuous 20 codings whithin a period of time, can be received
Number when, i.e., judgement can carry out being powered on for guide rail；If the signal that can not be received signal or receive is imperfect, discontinuous,
All illustrate that radio frequency reception end has not been entered into predeterminable area, that is, judges that guide rail still keeps standby mode.
After master controller receives the encoded signal that RF Receiving Device receives, work can be decoded to it rapidly,
Identify its information of vehicles and calculate speed etc., control according to demand after electrical switching apparatus quick response come complete guide rail open and
Shutdown task.
The utility model judges signal using master controller itself recognition methods, not improves judgement identification side
Method.
It, can be because the working band of the two be excessively close when the transmitting coil hypotelorism of ground induction coil and electrical supply rail
Cause the two to interfere with each other, ground induction coil is easy to burn out since transmitting coil can generate high-power high-strength magnetic field, one
As all can ground induction coil install the electromagnetic interference that very far it is generated with transmitting coil apart from electrical supply rail.But it is setting
During meter, it is desirable to which detecting distance is close as far as possible, and RF Receiving Device is located at electrical supply rail front end about 30cm when actual installation
Place realizes that automobile can make in different travel speeds after electrical switching apparatus quick response.
Described above is only to utilize radio location detection system control dynamic radio power supply segmented guide rail switching system
