Alert, continue detection vehicle speed value..
Assuming that the Zhou Changwei L of wheel rim, install m permanent magnet on wheel rim, then the mileage value maximum error recorded is L/
m.Analyze through comprehensive, the design takes m=2.When wheel every revolution, by switching Hall components sensor acquisition to
Pulse signal, and interrupt 0 end input from pin P3.2, sensor often obtains a pulse signal and i.e. once counts system offer
Interrupt.Interrupting representing vehicle wheel rotation half-turn, it is mileage value that the product of the perimeter L interrupting number n and wheel rim is multiplied by m more every time.Regularly
Device T0 timing 1s just can calculate instantaneous velocity v.When v is more than the speed limit set, send sound and light alarm.
Hall device has many advantages, their sound construction, volume are little, lightweight, life-span length, easy for installation, merit
Consume little, frequency is high (up to 1MHz), vibration resistance, the pollution not being afraid of dust, greasy dirt, steam and smog etc. or corrosion.Hall is linear
The precision of device is high, the linearity is good；Hall switch device is contactless, nothing is worn and torn, output waveform is clear, non-jitter, nothing are knock-oned, position
Put repeatable accuracy high.Take the hall device operating temperature range width of various compensation and protective measure, up to-55 DEG C～150
℃.Can divide them into according to the function of hall device: Hall linear unit and Hall switch device, the former exports analog quantity,
The latter exports digital quantity.Their application can be divided into by the character of detected object: directly application and indirect application.The former
Being magnetic field or the magnetic characteristic directly detecting object under inspection itself, the latter is the artificial magnetic field arranged on detection detected object,
The carrier of the information being detected is made with this magnetic field.By it, by many non-electrical, physical quantity such as power, moment, the positions of non-magnetic
Put, time etc. that displacement, speed, acceleration, angle, angular velocity, revolution, rotating speed and duty change, be transformed into
Electricity detects and controls.
A44E Integrated Hall switch is by manostat A, Hall voltage generator (i.e. silicon Hall plate) B, difference amplifier C, close
Special trigger D and five essential part compositions of OC door output E, at power end making alive Vcc, be added in Hall after manostat voltage stabilizing
The two ends of electric potential generator, according to Hall effect principle, when Hall plate is in magnetic field, pass in the direction being perpendicular to magnetic field
Electric current, then will produce Hull voltage VH output with on both perpendicular direction, and the amplified device of VH signal send after amplifying
To Schmidt trigger shaping so that it is become square wave and be transported to the output of OC door.When the magnetic field applied reaches operating point, trigger is defeated
Going out high voltage (relative to earth potential), make triode ON, now OC gate output terminal output low-voltage, the most this state is
Open.When the magnetic field applied reaches point of release, trigger output low-voltage, audion ends, makes OC door output HIGH voltage, this
State is for closing.Such twice voltage transformation, makes Hall switch complete a switch motion.Operating point and the difference one of point of release
Fixed, this difference is referred to as magnetic hysteresis, and in this difference, V0 keeps constant, thus makes switch output reliable and stable, this namely current collection become
Hall switch passes
One of sensor good characteristic.Sensor key property is its output characteristics, i.e. input magnetic induction density B and output voltage
Relation between V0.
It has been investigated that, the event of carriage for children disaster, occur in the case of light is very dark the most around, therefore arrange certainly
Dynamic lighting module so that in the case of dim, provide strong illumination for child, it is to avoid the generation of peril.
Energy conversion module is set, is greatly saved resource
NFC module is set so that client is set up wireless telecommunications with the speed measuring device of child and is connected, thus accomplishes that the moment supervises youngster
Perambulator speed, when beyond setting speed, reminding guardian the most at once, is supervised child's reduction of speed by guardian, meanwhile, when car exceeds the speed limit
After, warning circuit can be reported to the police it is known that speed drops to certain speed, it is to avoid due to negligence, and to cause irremediable fearful
Consequence.
Weight induction module, and weight preset to controller (single-chip microcomputer)-max. speed correspondence table are set, (described weight-
Max. speed correspondence table is to draw rational correspondence according to numerous experiments), eliminate the difference due to vehicle load, inertia is not
With, same maximum speed is set, normalized mode increases the probability of the generation of peril.
At least can reach following beneficial effect: overcome child's bicycle riding speed in prior art not limit, prison
Superintend and direct that people is careless and inadvertent or bicycle speed maximum limit arranges unreasonable, cause the defect that peril frequently occurs, simultaneously gram
Take child's bicycle and not there is automatic illuminating function, when causing dim, the defect such as peril frequently generation..
Finally it is noted that the foregoing is only the preferred embodiments of the present invention, it is not limited to the present invention,
Although being described in detail the present invention with reference to previous embodiment, for a person skilled in the art, it still may be used
So that the technical scheme described in foregoing embodiments to be modified, or wherein portion of techniques feature is carried out equivalent.
All within the spirit and principles in the present invention, any modification, equivalent substitution and improvement etc. made, should be included in the present invention's
Within protection domain.
