Description
Technical field
The present invention relates to electric bicycle antitheft alarm, more particularly, to NFC electric bicycle antitheft alarms.
Background technology
Increased with the ownership of electric car, the phenomenon that vehicle is stolen is outstanding day by day.In consideration of it, most of car owners give
Vehicle has installed electronic alarm additional, its operation principle is to trigger alarm equipment alarm by Vibration induction.But this induction mode
False alarm is easily lead to, as vehicle is touched by other people accidentally, and runs into and thunders or the larger sounds such as firecrackers are rung, alarm
Device, which will be rung, not to stop.And one trolley ring, the vehicle for being usually also possible to trigger side is rung together, so, its
The noise of generation causes the phenomenon that disturbs residents also commonplace.Originally the alarm as anti-theft alarm effect, which becomes, " to disturb residents
Device ".Moreover, electronic alarm all relies on the storage battery power supply on car now.As a result some confirmed thieves, which understand, finds alarm
Installation site, and power cord is cut rapidly, such alarm will lose the function of application, and thief still can be quick by vehicle
Start and ride away.
The content of the invention
The purpose of the present invention is exactly to solve the above-mentioned problems, there is provided a kind of preferable NFC electric bicycles of anti-theft effect
Burglar alarm.
To achieve these goals, the present invention adopts the following technical scheme that：A kind of NFC electric bicycle antitheft alarms,
It is characterised in that it includes tamper-proof MCU, the NFC reading circuits for reading NFC tag information, loudspeaker, electric power management circuit,
Control relay circuit, electromobile battery and main motor control module；
The NFC reading circuits are connected to MCU, and loudspeaker are connected to MCU by audio driver module, and electric power management circuit connects respectively
In electromobile battery and MCU, control relay circuit is connected to MCU, electromobile battery and main motor control module respectively, electricity
Door lock is connected to MCU and main motor control module respectively, and main motor control module is connected to main motor.
Further：Angular-rate sensor for detecting electric bicycle wheel state is connected to MCU.
Further：Alarm internal battery is connected to electric power management circuit.
Further：The alarm internal battery is lithium battery.
Compared with prior art, the present invention has the advantages that：Hardware device of the present invention is safe and reliable, and cost is low
Honest and clean, anti-theft effect is preferable, suitable for extensive use.
Brief description of the drawings
Fig. 1 is NFC electric bicycle antitheft alarm module maps in embodiment.
Embodiment
Referring to Fig. 1, a kind of NFC electric bicycle antitheft alarms, including tamper-proof MCU, for reading NFC tag information
NFC reading circuits, loudspeaker, electric power management circuit, control relay circuit, electromobile battery and main motor control module；
The NFC reading circuits are connected to MCU, and loudspeaker are connected to MCU by audio driver module, and electric power management circuit is connected to electric car respectively
Storage battery and MCU, control relay circuit are connected to MCU, electromobile battery and main motor control module, electric door lock difference respectively
MCU and main motor control module are connected to, main motor control module is connected to main motor.
Angular-rate sensor for detecting electric bicycle wheel state is connected to MCU.Alarm internal battery is connected to
Electric power management circuit.The alarm internal battery is lithium battery.
Alarm specific workflow is as follows：
(1) when needing car locking, first the electric door lock of headstock is pinned, car owner also needs to exist supporting NFC label touching
The NFC Card Readers region of vehicle, NFC reading circuits can give MCU feedback signals.And MCU then controls audio driven after signal is received
Module, driving loudspeaker are sent into state of alert prompt tone.At the same time, MCU also can output level control relay (relay
Control circuit), storage battery (electromobile battery) cuts off main motor current supply circuit.
(2) when needing to use vehicle, car owner need to touch NFC label again in the NFC Card Readers region of vehicle.MCU connects
Signal is received, and controls loudspeaker to send and releases state of alert prompt tone.Electric door lock is opened at this time, and MCU receives unlocking signal, i.e.,
Relay (control relay circuit) closure is controlled, connects storage battery (electromobile battery) to main motor current supply circuit.
(3) vehicle opens the electric door lock of headstock in the case where not releasing the state of alert by NFC label, and MCU then only connects
Receive the signal that electric door lock is fed back to.At this time, MCU will control audio driver module, and driving loudspeaker sound the alarm.And this
When, relay (control relay circuit) controlled can be still off, and main motor does not have power supply to be supplied to, and vehicle can not
Start.This needs brushes NFC label, and can sound all clear sound.So even if robber pries open on car lock used, but also without
Method starts car, and alarm song will not eliminate, and allows robber to be difficult smoothly to steal car.
(4) situation that automobile steals is carried on by thief for occurring whole electric vehicle.When being in the state of alert, car
Born away or moved, the angular-rate sensor that this process can be in trigger circuit, MCU detects these letters from sensor in real time
Number, i.e., loudspeaker can be controlled to send alarm sound.
(5) under extreme conditions, inevitably there is the possibility that robber destroys in-car lead.If the power supply meeting of alarm
Therefore it is cut off, internal electric power management circuit can automatically switch to built-in lithium battery, and ensure within the regular hour still
The function of alarm can be continued to execute.
With the label application technology of NFC near field communication, each electric car is allowed all to carry independent sequence number as one
Individual, and by vehicle unlock unique authority transfer to NFC label so that even if robber all pries open the lock of vehicle, also according to
The old authority that cannot obtain vehicle launch.This causes the stealing difficulty of stealer to greatly increase, and the pilferage time for extending it more may be used
Further to reduce the probability that vehicle is stolen.Even if can finally steal car, still main motor can not be made to electrically activate, this is big
Big increase lawless people robs the use cost for carrying out electric vehicle to stealing, and has to the stolen probability for further reducing electric car vehicle
Significance.
The power supply of vehicle is controlled by the main control chip of alarm, and each alarm is corresponding with a NFC label, is stored up in label
There is a fixed sequence number, these sequence numbers are unique, and can not be replicated.These unique sequence numbers,
It is unique authority that main motor power supply is opened in master control.NFC label is to substitute the remote controler of traditional alarm, for opening or closing
Close the alarm function of vehicle.NFC identification circuits in warning device can be freely mounted to the place easy to Card Reader operation, such as headstock
On the inside of instrument.Discard tradition the shock detection mode of alarm, uses electric door lock and angular-rate sensor instead to be carried to governor circuit
For triggering alarm signal.The part of alarm can be integrated in a firm space with the main motor control module of vehicle
It is interior, reduce burglar to greatest extent and achieve the purpose that to close warning function by destroying alarm lead.Alarm weighs every time
Power on, all acquiescence enters alarm lock-out state, need to be unlocked by NFC label.
The foregoing is merely the preferred embodiment of the present invention, protection scope of the present invention is not limited in above-mentioned embodiment party
Formula, every technical solution for belonging to the principle of the invention belong to protection scope of the present invention.For those skilled in the art
Speech, some improvement carried out on the premise of the principle of the present invention is not departed from, these improvement also should be regarded as the protection model of the present invention
Enclose.
