Description
Technical field
The present invention relates to automotive field, relate in particular to a kind of alarms and security systems for automobiles and theft preventing method.
Background technology
In recent years, people more and more pay close attention to automobile burglar, once because automobile is stolen, will bring huge loss to family. Current alarms and security systems for automobiles is of a great variety, as: together with steering wheel is hooked in long rod type two ends with the fixture (as brake, clutch etc.) in driver's cabin, steering wheel can not be rotated and maybe can not depress clutch, brake etc., vehicle can not be travelled. This type of anti-theft device exposes clearly outside, stop in unserviced area, still can by offender easily sawed-off, prize the bad or steering wheel of dismantling, make it to lose anti-theft function. Even if electronic anti-theft device is installed also may lose efficacy because of power-off or fault. Some protection defending locks are also because exposing and easily pounded destruction by sled outside.
Along with global positioning system (Globalpositioningsystem, GPS) be widely used in anti-thefting monitoring and the navigation aspect of automobile, it links together by existing GSM or CDMA module, obtain the GPS information of automobile by GPS, then by GSM or CDMA module, GPS information is offered to client in modes such as note, GPRS or audio calls, client is by the position of corresponding software display automobile, to realize the function of anti-thefting monitoring. But many automobiles that GPS burglary-resisting installation has been installed, still do not escape stolen destiny, as can be seen here, existing GPS burglary-resisting installation can not well reach antitheft object.
Biological characteristic is people's inherent attribute, has very strong self stability and individual difference, and face is the key character of the interpersonal difference of difference. The method of utilizing face characteristic to carry out authentication has directly, friendly, feature easily, is easily user's acceptance. Therefore biometrics identification technology becomes a focus of current research, needs a kind of safe and effective alarms and security systems for automobiles based on living things feature recognition of exploitation badly.
Summary of the invention
For the problems referred to above, the invention provides a kind of alarms and security systems for automobiles and theft preventing method, the mode combining with voice password by face-image is carried out Information Proofreading, thereby effectively identifies driver's legitimacy, reaches antitheft function.
For realizing above-mentioned purpose of the present invention, the invention provides a kind of alarms and security systems for automobiles, comprising: computer, single chip microcomputer driving circuit, acoustic control identification module, camera, automotive control circuit and buzzer; Described acoustic control identification module comprises sound storage module and sound conduction module.
Described camera is arranged on the console of automobile, for gathering the facial image information of wanting driver; Described Computer Storage car owner's facial image information, and compare according to the facial image information of wanting driver of this facial image information and camera collection, whether judgement wants driver legal, output legal signal or illegal signals. Driver's voice password is wanted in described sound storage module storage, transfers to computer by described sound conduction module, compares with the voice password of Computer Storage, and whether judgement wants driver legal, output legal signal or illegal signals. Signal and sound control signal that described single chip microcomputer driving circuit receiving computer sends, in the time that two signals are legal signal, output control signal removes to control automotive control circuit, carries out release; When there being one to be illegal signals or while being illegal signals, output control signal removes to control buzzer in two signals, the buzzer sound that gives the alarm.
The present invention also provides a kind of automobile anti-theft method, and concrete steps are.
Step 100: to wanting driver's facial image information and car owner's facial image information of storage to compare, export legal signal or illegal signals by computer.
Step 200: to wanting driver's voice password and car owner's voice password of storage to compare, export legal signal or illegal signals by computer.
Step 300: when above-mentioned steps 100 is all exported legal signal with step 200, automotive control circuit carries out release.
Step 400: when above-mentioned steps 100 is exported illegal signals or all exports illegal signals with one of step 200, buzzer gives the alarm.
Compared with prior art beneficial effect of the present invention.
Alarms and security systems for automobiles provided by the invention and theft preventing method, it is a kind of initiative recognition of non-infringement formula, have directly, friendly, feature easily, the mode combining with voice password by face-image is carried out double-point information check and correction, thereby effectively identify driver's legitimacy, reach antitheft function; And can solve the shortcoming of mechanical type and electronic type anti-theft device, effectively prevent that criminal from reaching the object of car theft by stealing key.
