Specific embodiment
It elaborates with reference to the accompanying drawing to the present invention.
As shown in Figure 1, 2, bicycle ranging safety arrestment auxiliary device of the present invention includes detection part 1, control unit
Divide 2 and execution part 3, and detection part 1, control section 2 and execution part 3 pass through circuit connection.The detection part 1 is pacified
Mounted in front of the car, control section is mounted below vehicle seat-pad, and execution part is mounted on vehicle frame and after acting on vehicle
Wheel.
As shown in figure 3, detection part 1 of the present invention is ultrasonic sensor modules, module includes ultrasonic wave transmitting
Device, receiver and control circuit, ultrasonic transmitter sends square wave, returns and be received by the receiver after chance barrier, through control electricity
Road sends a signal to control section.The supersonic sensing module has 4 interfaces, respectively 5V power interface 1.1, TRIG triggering
Control signal input 1.2, ECHO response signal delivery outlet 1.3 and GND ground wire 1.4.The ultrasonic sensor modules base
This working principle is as follows:
(1) ranging is triggered using I/O port TRIG, at least high level signal of 10us；
(2) module sends the square wave of 8 40khz automatically, has detected whether signal return automatically；
(3) there is signal return, a high level is exported by I/O port ECHO, high level duration is exactly ultrasonic wave
From the time for being emitted to return.Measuring distance=(the high level time * velocity of sound (340M/S))/2；
Detection part provides the square wave of 2cm-400cm by ultrasonic transmitter, realizes contactless distance perception measurement of power
Can, range accuracy may be up to 3mm.
The signal received is sent to control section 2 by detection part 1, and control section is using single-chip microcontroller as micro-control master
Machine is connected by way of code and drives ultrasonic unit and slow brake apparatus.Single-chip microcontroller is in the present embodiment
Stm32F1ZET6 single-chip microcontroller, which does not use external power supply, but fills an electromagnetic induction device in wheel there.Such as
Fig. 4, shown in 5, installed on cycle wheel for electromagnetic induction device, wheel is conductor, when cycle wheel do not stall it is dynamic
When, construct a small magnetic field to power for single-chip microcontroller on wheel both sides, because the driving voltage of single-chip microcontroller does not need very high 5V i.e.
Can, so as to meet control section electric power needs.
As shown in fig. 6, execution part 3 of the present invention uses electromagnetic whirlpool brake device, on rear-wheel.The device
Including electromagnet 3.1, spring 3.2, friction catch rubber block 3.3 and electromagnetic brake 3.4, electromagnet 3.1 is mounted on electromagnetic brake 3.4

Punching move electromagnetic brake start give rear-wheel apply frictional resistance, the speed of traveling is faster, the wheel rotor speed as conductor also more it is fast simultaneously
And cutting magnetic induction line, the voltage that can must be generated by E=BLVsinA is also bigger, therefore buffer brake device is also just because voltage is got over
Greatly, the resistance of application is bigger, and friction catch rubber BOB(beginning of block) squeezes rear wheel hub at this time, and bicycle is made to slow down, traveling
The voltage of the slower generation of speed is also just smaller, and the resistance of application is with regard to smaller, when bicycle in security restriction apart from interior pressure because stopping
When only or when not needing to carry out the artificial parking of safe distance detection, wheel no longer cutting magnetic induction line, single-chip microcontroller is also just due to a lack of confession
Electricity and stop working.
Bicycle ranging safety arrestment auxiliary device working principle of the present invention is as follows:
When bicycle, which enters, to be limited within the scope of safe distance, detection part receives the signal of feedback and is sent to control
Part processed, through single-chip microcontroller processing output order to execution part, electromagnetic whirlpool brake device is connected to instruction at this time, gives rear-wheel
Applying frictional resistance makes bicycle slow down, until bicycle stops in security restriction apart from interior pressure.
