Specific embodiment
Explanation is further described to the technical solution of the utility model below by specific embodiment.
Embodiment 1：
As shown in figure 1, the antijoyride device of the public bicycles of the present embodiment, including electromagnetic lock 1, strip flexible wirerope
2nd, tapered end 3, induction coil L1, signal processing circuit.Electromagnetic lock 1 includes lock body and lock core, and the lock body of electromagnetic lock 1 is fixed on public
On the pile at Cycle Hire station, the lock body of electromagnetic lock 1 also with one end of wirerope 2 be fixedly connected, the other end of wirerope 2 is along sense
Answer the interspersed induction coil L1 of axis direction of coil L1 and be connected with tapered end 3.The lock core of electromagnetic lock 1 forms magnetic conduction groove, tapered end 3
Free end form raised with the magnetic conduction of magnetic conduction matching grooves, make to form magnetic flux between tapered end 3, wirerope 2, the three of electromagnetic lock 1 and return
Road, the magnetic conduction projection of tapered end 3 is inserted or pull out in the magnetic conduction groove of the lock core of electromagnetic lock 1, tapered end 3 is fixed or be located away from electromagnetic lock
1；The two ends of induction coil L1 form closed-loop path with signal processing circuit.Using the original for changing change of flux winding inductance quantity
Reason, inductance value is many times higher with respect to non-occluded state in the closure state of wirerope 2, and it is humorous that induction coil L1 and resonant capacitance C1 is produced
Vibration frequency can change as whether chain closes, and feed back locking or the unlocking signal of public bicycles.
Using the principle for changing change of flux winding inductance quantity, inductance value computing formula L=uN2S/l,
L：The inductance value of induction coil,
l：The length of wirerope,
N：The number of turns of induction coil,
S：The sectional area of chain,
u：The permeability of wirerope,
Wherein the number of turns of the length of wirerope, sectional area and induction coil is definite value, because the permeability of air is than wirerope
Permeability it is much lower, therefore inductance value relative non-occluded state when wirerope is closed is many times higher.
By wirerope, electromagnetic lock, tapered end synergy, the interspersed public bicycles wheel hub of wirerope locks public bicycles
Or unblock, public bicycles wheel hub is metal material, and metal material has good electric conductivity, if working as an additional higher-order of oscillation
Signal is coupling in when on wheel hub by wirerope, and metal wheel hub can be presented stronger impedance to the amplitude of high-frequency oscillation signal, and shake
The impedance that the amplitude of signal produces to wheel hub is swung to be directly proportional.Judge whether electromagnetic lock 1 has wheel hub quilt after locking by the characteristic
Lock, moreover it is possible to calculated several wheel hubs and be locked.As shown in Fig. 2 the equivalent circuit after being locked for multiple wheel hubs, Lc1 and
Lc2 is the equivalent public bicycles wheel hub for sealing in wirerope, is equivalent to a circle coil.Lr1 and Lr2 are equivalent wheel hub metal materials one
The resistance of circle.In addition, there is turn ratio between L1 and Lc1, Lc2, the sampling of whole measurement is had no effect on.
The amplitude U=Us at induction coil two ends × (R1/R2/Rn)/(Rs+ (R1/R2/Rn)),
U：The signal amplitude at induction coil two ends,
Us：Pumping signal amplitude,
Rs：Signal source equivalent internal resistance,
R1, R2, Rn are wheel hub equivalent resistance,
N is to seal in wirerope wheel hub quantity,
Understand induction coil both end voltage and seal in wirerope wheel hub quantity from the formula to be inversely proportional.
Signal processing circuit includes high-frequency signal oscillating circuit and frequency width translation circuit.High-frequency oscillation signal is passed through into wirerope
2 are coupled on public bicycles wheel hub, and tapered end 3 is not inserted into oscillating circuit during lock body and is in significantly oscillatory regime, and tapered end 3 is inserted
Oscillator amplitude is significantly decayed during lock body, frequency of oscillation step-down.Shaken when the internal lock of wirerope 2 has public bicycles wheel hub to increase
The amplitude of swinging can be dragged down once again.
As shown in figure 3, being signal processing circuitry block diagram, can obtain wirerope by measurement surveys after closed and disconnected
Amount induction coil L1 and resonant capacitance C1 respectively obtains two resonant frequency respectively f1~f2.Voltage controlled oscillator is sent out in triangular wave
Obtain exporting the frequency separation for obtaining a f3~f4 under the control of raw device, adjust triangular-wave generator amplitude and voltage controlled oscillator
Range make f1 be slightly less than f3 and f2 can just to cover the resonance of L1 and C1 slightly larger than the swept frequency range of f4, i.e. voltage controlled oscillator
Frequency separation.The resonance circuit that the output signal of voltage controlled oscillator is constituted by power amplifier output to L1 and C1.
When the frequency sweep of voltage controlled oscillator is equal with L1 and C1 resonant frequencies, resonant frequency amplitude is maximum.Design low pass is put
The cut-off frequency of big device is equal to the frequency f1 of wirerope closure, so when wirerope is not closed, resonance signal by low-pass amplifier,
Output switching signal after amplitude detection, amplitude judging circuit；Otherwise signal cannot pass through low-pass amplifier after wirerope closure, so
It is unable to output signal.
Bandpass amplifier centre frequency is equal to the frequency f1 of wirerope closure, if low without wheel hub leakage inductance after locking, resonance signal
The full amplitude u0 of output is followed by bandpass amplifier, amplitude detection, signal, signal follows output amplitude if having a wheel hub
U1, and meet relations of the u0 much larger than u1.Signal follows output amplitude ux, wheel count x=(u1- if having x wheel hub
Ux)/Uleve, wherein Uleve are the signal amplitude that every one wheel hub of increase declines, so as to calculate wheel hub quantity.
The antijoyride device of the public bicycles of the present embodiment can compatible different shape, different size of public affairs using flexible wirerope
Common bicycle, and many wheel hubs of public bicycles can be pinned on same wirerope, preferably solve current public bicycles
The inadequate problem of rental station parking stake；The antijoyride device simple structure, operation is rapid, can save rent and return the car the time, improves and rents
Return the car efficiency.
Embodiment 2：
The present embodiment is with the difference of embodiment 1：Lock core can be controlled to perform locking and unlocking by controller
Action, locking and unlocking action are actively initiated by controller, while lock core feedback is unlocked and the current unlocking condition of locking, instruction is
It is no to unlock successfully, the control to electromagnetic lock, and the operation for reading vehicle fleet size are completed by the control logic of its own.Realize
The intellectuality of the antijoyride device of public bicycles.
Preferred embodiment of the present utility model and principle are described in detail above, to the ordinary skill people of this area
For member, according to the thought that the utility model is provided, be will change in specific embodiment, and these changes should also be regarded
It is protection domain of the present utility model.
