Unit, Internet of Things communication module, GPS locating module and alarm module are powered.Further, described switching Hall components sensor
Circuit includes A44E hall sensing.
Further, control method based on bicycle monitoring system, comprise the following steps:
A., at least one permanent magnet, wheel every revolution, switching Hall components sensor circuit are installed on bicycle rim
Gather a pulse signal, and carry out counting and calculating speed to control unit by pulse signal transmission;
B. calculating rate results and bicycle location information is sent to server by Internet of Things communication module, server is to speed
Value carries out data process, and the bicycle maximum speed simultaneously calculating rate results also preset with control unit compares, if meter
The velocity amplitude calculated is more than preset speed value, then warning circuit is reported to the police, and whether the unit judges that tests the speed speed voluntarily reduces and low
In bicycle speed maximum, if falling below speed maximum, then stop alarm, otherwise continue to report to the police, until speed drops
Low within preset speed;
C. client data after server acquisition processes
In step B, server carries out data process and includes, according to same period and same geographical location information vehicle speed value
Self-moving vehicle information is classified, to the vehicle speed value of sorted self-moving vehicle by being ranked up from big to small, and adds up super
Go out the number of vehicles of setting speed size.
Step C also includes, after the data after client acquisition process, according to different traffic locations and the scope of hypervelocity,
Searching corresponding bicycle management measure and suggestion by the Internet, and be downloaded, prompting relevant staff take accordingly
Speed limit measure.
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.Energy conversion module is set and is greatly saved resource.
Alarm unit is set, when the travel speed of bicycle exceedes control unit maximum speed set in advance value, meeting
Triggering warning circuit to report to the police, the warning people that rides reduces speed, otherwise can report to the police always, arranges warning circuit and can restrain and ride
The speed-raising desire of pedestrian, reduces and causes potential safety hazard owing to speed is too high.
By utilizing Internet of Things communication module to send bicycle vehicle traveling information to local server, and information is entered
Row processes, and on-site vehicle management and control personnel carry out corresponding control according to the scope that address violating the regulations and vehicles peccancy exceed the speed limit, thus gram
Take potential safety hazard present in traffic.
Locating module is set and concentrates the place of hypervelocity in order to add up bicycle, it is possible to make staff rapidly and efficiently right
The geographical position concentrating hypervelocity takes appropriate measures.
Client can also solve suggestion by internet hunt according to bicycle speed information, alleviate staff
Work load.
At least can reach following beneficial effect: overcome the supervision means lacking bicycle in prior art, cause voluntarily
The illegal traffic rules of car, the defect that traffic accident occurrence probability significantly increases, improve in traffic and the speed of bicycle is monitored, and according to
The concentrative time interval of bicycle overspeed and place, formulate corresponding plan, reduces the potential safety hazard in traffic, arranges warning electricity simultaneously
Road, reminds reduction of speed further to reduce potential safety hazard.
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.
