Alarms and security systems for automobiles
Technical field
The utility model relates to a kind of anti-joyride device, relates in particular to a kind of alarms and security systems for automobiles.
Background technology
Along with automobile is universal widely, automobile burglar also becomes the problem that people are concerned about, alarms and security systems for automobiles in the market mainly contains following several:
1, mechanical lock class car alarm, this class Car Burglar Alarm is mainly to install mechanical device additional and the action of restricting vehicle on vehicle steering, gear or tire, this anti-joyride device price general charged is cheap, but mechanical key is easy to be replicated, and whole anti-joyride device is heavier.
2, electron key class Car Burglar Alarm, this class Car Burglar Alarm is mainly that mechanical key is reequiped, and encapsulates IC integrated package in key, installs decoder on lock additional, a kind of shortcoming of Car Burglar Alarm before this Car Burglar Alarm has overcome to a great extent, but still there is the possibility that key is stolen or lose.
3, satellite positioning is followed the trail of class Car Burglar Alarm, and the scientific and technological content of this class Car Burglar Alarm is higher, but price and maintenance cost are also all very high, and in the situation that battery electric quantity is finished, anti-joyride device just cannot be worked.
Utility model content
Technical problem to be solved in the utility model is for above-mentioned the deficiencies in the prior art, and a kind of safe alarms and security systems for automobiles is provided.
For solving the problems of the technologies described above, the technical scheme that the utility model is taked is: a kind of alarms and security systems for automobiles, comprise micro controller system, fingerprint acquisition device, input keyboard, sonac, relay, explosion-proof solenoid valve, annunciator, communication module and automobile power source, described fingerprint acquisition device, input keyboard, sonac are connected with the input end of micro controller system respectively, the first mouth of micro controller system is connected with explosion-proof solenoid valve by relay, and other mouths are connected with annunciator, communication module and automobile power source respectively.
As the preferred technical scheme of the utility model,
also comprise read-out, described read-out is connected with the mouth of micro controller system.
As the preferred technical scheme of the utility model, described communication module comprises vehicle-mounted SIM.
As the preferred technical scheme of the utility model, described sonac comprises ultrasonic transmitter and ultrasonic receiver, and described ultrasonic receiver is for receiving the super sonic that described ultrasonic transmitter sends.
On alarms and security systems for automobiles of the present utility model, fingerprint recognition system is housed, utilize the fingerprint of input as unique foundation of unblanking, improved the safety of this device, adopt Single-chip Controlling automobile power source, only having fingerprint to check correct rear automobile power source could connect, adopt explosion-proof solenoid valve to control automobile oil-way, avoided causing oil-break because of accident power-off in driving process.This alarms and security systems for automobiles is also equipped with sonac, can judge whether automobile position changes, even if car stealer has cracked system of fingerprints, car is driven away, sonac can be judged the change of automobile position and signal is sent to micro controller system, the vehicle-mounted SIM of Single-chip Controlling sends message to car owner's mobile phone, remind car owner's vehicle abnormality situation, and can, according to this SIM location automobile position, reach antitheft object.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described further.
The specific embodiment
embodiment 1
Referring to Fig. 1, this alarms and security systems for automobiles, comprise micro controller system, fingerprint acquisition device, input keyboard, sonac, relay, explosion-proof solenoid valve, annunciator, communication module, automobile power source and read-out, described fingerprint acquisition device, input keyboard, sonac are connected with the input end of micro controller system respectively, the first mouth of micro controller system is connected with explosion-proof solenoid valve by relay, and other mouths are connected with annunciator, communication module, automobile power source and read-out respectively.Described sonac comprises ultrasonic transmitter and ultrasonic receiver, and described ultrasonic receiver is for receiving the super sonic that described ultrasonic transmitter sends.Communication module is provided with vehicle-mounted SIM.Micro controller system adopts 8051 Series MCU, and communication module is TC35i chip.
As Fig. 1, by vehicle-mounted SIM and a SIM cards of mobile phones binding, fingerprint acquisition device is directly connected to the input end of micro controller system, first by fingerprint acquisition device gather car owner and car owner approval people fingerprint and be stored in micro controller system, during use, the fingerprint that micro controller system collects fingerprint acquisition device and the contrast of the fingerprint in data bank, if unmatched words, do not mate in demonstration screen display, if coupling MCU Instruction is connected automobile power source, and commands relays starts explosion-proof solenoid valve, automobile oil-way is connected, and automobile can normally travel.
If when someone destroys alarms and security systems for automobiles, MCU Instruction annunciator is opened, and sounds the alarm, and reminds other people to note.
Ultrasonic transmitter in ultrasonic transduter sends super sonic at set intervals one time, catches hypracoustic backward wave by ultrasonic receiver simultaneously, and records hypracoustic transmitting and reflection used time, then calculates the distance of system and obstacle.If change of distance surpasses certain threshold value, think and invasion signal detected, ultrasonic transduter sends a signal to micro controller system, vehicle-mounted SIM in Single-chip Controlling communication module sends the SIM cards of mobile phones to binding with the note of address information, remind car owner's vehicle abnormality situation, and can, according to this SIM location automobile position, even if car stealer breaks through system of fingerprints, car be driven away, also can in time car be given for change, reach the effect of double anti-theft.
