The first use procedure of embodiment:
As shown in Figure 2, start, glass break detection device does not work, and when thief breaks vehicle glass into pieces time, after glass break detection device is touched by the sound frequency of vehicle glass fragmentation, glass break detection device is driven immediately,
After glass break detection device converts electric signal to the high-frequency sound signal of vehicle glass fragmentation, this electric signal transmission is carried out filtering to filter, and filters filter falls N/R electric signal, obtains a purer electric signal.Again this pure electric signal transmission is carried out spectral analysis to frequency spectrum analyzer, comprise the power of this electric signal, frequency, distortion etc. are analyzed, and judge that whether glass is broken.If the electric signal that this electric signal and the broken sound frequency of vehicle glass transmit does not match, then think that vehicle glass is intact.If the electric signal that this electric signal and the broken sound frequency of vehicle glass transmit matches, then think that vehicle glass is broken into pieces by thief.When confirming that vehicle glass is broken into pieces by thief after frequency spectrum analyzer analysis, so, transfer passive infrared detector, microphone, camera and vibration sensor carries out work to embedded computer at once.
Passive infrared detector judges whether have human body temperature to change in car, has human body temperature to change when passive infrared detector detects in car, just human body temperature change electric signal transmission to embedded computer.
In microphone, whether microphone hears the sound of the sound that glass fragment drops or robber, if the sound of the sound that glass fragment drops or robber heard by microphone, just the electric signal transmission of this sound to embedded computer.
Start camera, whether camera is seen glass breaking or is had thief into the car, if camera sees glass breaking or have thief into the car, so, camera is just sent to embedded computer the vehicle window picture photographed; If it is intact that camera photographed glass breaking, then terminated.
Whether vibration sensor experiences the vibration of glass breaking, judge whether have unusual fluctuation in car, and vibration sensor vibrates the electric signal transmission that produces to unusual fluctuation detector glass breaking, unusual fluctuation detector further confirms to detect to the electric signal that vibration sensor is sent, and reduces wrong report.If there is people to stir the sound frequency having people to breathe in the sound frequency of article or car in the frequency of the result that unusual fluctuation detector the detects broken chatter that is vehicle glass or car.So unusual fluctuation detector just detected electric signal transmission to embedded computer.
Embedded computer is to passive infrared detector, microphone, above-mentioned every electric signal that camera and vibration sensor transmit and the electric signal pre-set are analyzed, confirm whether above four all set up, if above four are all set up, so, embedded computer is just respectively to annunciator, antitheft vehicle door lock, safety engine is locked, loudspeaker and 3G wireless signal transceiver send the instruction of work, annunciator starts immediately, antitheft vehicle door lock starts, safety engine lock starts, horn activation and 3G wireless signal transceiver start, start working, and operated data-signal is stored in memory device.
Annunciator sends alarm sound, if have people near automobile, just can after hearing sound, overtake immediately to look into and see if there is people and carrying out stealthy activity, meanwhile, the alarm sound that annunciator sends also can play fright effect to thief, carries out the active anti-theft of frightening alarm song, allow thief fear to be found, and automatically abandon the possibility continuing crime.
Antitheft vehicle door lock in car, opens car door with hand after stoping thief's breaking glass, and safety engine lock stops thief to drive away their vehicles, and carries out active anti-theft, reduces car owner's loss.
Prompting sound to thief play by loudspeaker, tells that thief abandons theft, and loudspeaker are also play warning that car owner sent by 3G mobile or advised sound, with the chimes of doom play 110 alarm stations and send.Thief know oneself monitored after, initiatively may abandon continuing theft, reduce the loss of car owner.
On the 3G mobile that 3G wireless signal transceiver is sent to signal stolen for automobile car owner and on 110 alarm stations, and open the audio frequency and video linkage function of camera, loudspeaker and microphone.After the 3G mobile of car owner receives anti-theft signal, car owner has been confirmed whether that people is in theft.
Car owner and and alarm station all with being seen vehicle glass and Che Nei situation by camera, and can be engaged in the dialogue to thief by loudspeaker and microphone.
Car owner can by the loudspeaker in the camera of 3G mobile and Che Nei and car and microphone, the situation that the automobile of omnibearing understanding oneself is current, car owner has been confirmed whether that people is in theft, if car owner confirms that the automobile of oneself is stolen by thief really, so car owner just can report a case to the security authorities to 110 alarm stations at once.3G wireless signal transceiver is reported to the police to 110 alarm stations simultaneously, and sends the particular location of the GPS location of stolen vehicle.After 110 alarm stations receive autoalarm signal, then to report a case to the security authorities situation according to the car owner that 110 alarm stations receive, determine whether responding.Determine that the need of the standard of responding be the warning whether 110 alarm stations receive car owner and automatic alarm platform simultaneously and send, if 110 alarm stations receive the warning that car owner and automatic alarm platform are sent simultaneously, so just responding immediately.The object done like this is, reduces wrong report, reduces unnecessary responding.
The second use procedure of embodiment and the first use procedure of embodiment similar, as shown in Figure 3, difference is, be driven to start the whole automobile burglar monitored control system based on voice recognition technology by glass break detection device, be turned into be driven to be driven with vibration sensor by glass break detection device and jointly start the whole automobile burglar monitored control system based on voice recognition technology.Glass just starts whole automobile burglar monitored control system when being broken and having unusual fluctuation in car, and in car, have that human body temperature changes, the sound of the sound that glass fragment drops or robber heard by microphone, camera sees glass breaking or have thief these above three when whether all setting up into the car, just start whole automobile burglar monitored control system.Comprehensive startup of the whole automobile burglar monitored control system based on voice recognition technology caused by two conditions.This embodiment can reduce rate of false alarm, improves the careful property of reporting to the police.
The third use procedure of embodiment and the first use procedure of embodiment similar, as shown in Figure 4, difference is, be driven to start the whole automobile burglar monitored control system based on voice recognition technology by glass break detection device, be turned into and driven by glass break detection device, microphone starts, passive infrared detector starts, camera starts and vibration sensor is driven to jointly start the whole automobile burglar monitored control system based on voice recognition technology, and only require whether microphone hears the sound of glass breaking, and do not require the sound of robber, because robber's music of speaking is different from the sound frequency of glass breaking, when not hearing the sound of glass breaking, microphone does not start, can power saving, also reduce wrong report simultaneously.After vibration sensor is driven, after needing to carry out unusual fluctuation detection, the electric signal that vibration sensor could be detected is to embedded computer.When all setting up for above five, just start the whole automobile burglar monitored control system based on voice recognition technology.This use procedure rate of false alarm is very low.
