Description
[technical field]
The invention belongs to the interleaving techniques field of wireless communication technology and automotive safety; Relate to a kind of automotive theft proof system, vehicle-mounted antitheft equipment and theft preventing method, be specifically related to a kind of a kind of automotive theft proof system, vehicle-mounted antitheft equipment and theft preventing method based on the Bluetooth of mobile phone checking.
[background technology]
Today that automobile is popularized day by day; Automobile burglar has become the very important problem of field of automobile safety; Existing automobile burglar technology is main concentrates mechanical lock or electronic remote remote control to lock face; Its principle also is based on the principle of lock being verified through key, and who has grasped key and has promptly obtained the checking to this lock, thereby has also just removed the safety control of this lock to automobile.
Common mechanical lock and unsafe reason just are that it is simple in structure, and the success ratio that cracks is too high, and lock the today that becomes main flow in the electronic remote remote control, and its safety is greatly improved than mechanical lock, and the difficulty that cracks also increases greatly.
The principle of work of electronic remote remote control lock automotive theft proof system is: the remote-control key of this system sends faint electromagnetic wave as emitter; Receiver in the automobile receives this electromagnetic wave signal; Through electronic controller ECU identification signal code, carry out opening again by the actr of this system/action of locking.The frequency of emitter emission is at 300MHZ～450MHZ; Belong to the high frequency radio wave signal, the transmitting frequency of this electric wave signal immobilizes, and other equipment that is easy to be positioned in its signal range is caught; Perhaps disturbed, so this anti-theft system safety is not high by the artificial interfering signal that applies.
In order to improve the difficulty that cracks of automotive theft proof system, people have expected Bluetooth technology is incorporated in the automotive theft proof system, major cause be bluetooth adopt be frequency hopping with and unique authentication and encryption technology.The simple automotive theft proof system of Bluetooth technology that adopts is divided into two types mostly:
One type is with Chinese utility model patent (application number: 03205938.8; The applying date: on 08 08th, 2003) disclosed a kind of car alarm that uses Bluetooth technology; The principle of work of this car alarm is such: the bluetooth mobile phone that detects the user when Car Burglar Alarm gets in the communication context of bluetooth; Confirm identity immediately mutually, begin swap date after confirming, Car Burglar Alarm automatically terminates antitheft immediately when signal strength arrives the intensity of user's setting; Otherwise after vehicle was flame-out, the user left vehicle, and signal strength Car Burglar Alarm automatic setting antitheft immediately when being lower than the intensity that the user sets.The shortcoming of this patent is: owing to need the bluetooth of the anti theft host on the car to open always; And at every moment scanning its near bluetooth equipment the time; The people could be very fast near vehicle the time search out the entrained bluetooth telephone of people; So its consumption of current of the anti theft host on the car will be very big, and the bluetooth of the anti theft host on the car opens always and is under the state of continuous scanning, and this provides time and chance for the passwords that the lawless person cracks bluetooth.
Another kind of is with Chinese invention patent (application number: 200810006181.3; The applying date: on 02 21st, 2008) disclosed automotive theft proof system and utilize bluetooth hand-held device Control of Automobile anti-theft system and the disclosed alarms and security systems for automobiles based on mobile phone of method and Chinese utility model patent (application number: 200820004097.3, the applying date: on 02 03rd, 2008) is in these two patents; In the process of removing anti-theft system, all need bluetooth cellular phone be taken out operation; Input pairing password, or need the M/C control command, such anti-theft system is not only controlled inconvenience; And because not disguised; So its safety also can be had a greatly reduced quality, this system also requires anti theft host on the car to be in the state of unlatching simultaneously, and time and chance are provided when cracking the key of bluetooth to the lawless person.
To above-mentioned shortcoming; China's utility model patent (publication number: CN201291830Y; Open day: on 08 19th, 2009) a kind of Bluetooth keyless vehicle alarm of infrared induction disclosed; It is on the basis of existing Bluetooth keyless vehicle alarm, to have increased the infrared induction module, judges whether have people or object to exist in the actual induction zone through the infrared induction module, and sends relevant information to core processor; The various signals that core processor will be received are handled, are judged, start the bluetooth communication module through core processor car owner's identity is confirmed.This patent is than the advantage of above-mentioned patent, can start the bluetooth communication module through infrared induction, has avoided the bluetooth communication module to be in opening always, has saved electric energy, has also reduced the probability that is cracked simultaneously.
But the safety of this car alarm does not obtain the raising of essence, and reason is infrared induction module role only is used to be used for discerning whether the someone exists in the actual induction zone; And specifically be the car owner; It can not play actv. and distinguish, so from the angle of safety, the robber just can open the bluetooth communication module as long as arrive in the induction region of infrared induction module; Thereby begin it is cracked; This and do not have the infrared induction module, the safety that directly lets the bluetooth communication module always be in opening is essentially identical, its safety is not significantly improved.
In addition on the one hand; Whether car is outer could discern the car owner near car because the induction region of its infrared induction module only extends to; Because it can not discern car owner's identity, so as long as people or object are arranged near car, then the bluetooth communication module is with regard to self-opening; This obviously is that bluetooth communication module job procedure is caused unnecessary interference, and frequent switch bluetooth communication module has also reduced its service life simultaneously.If the induction region of its infrared induction module is only in very little area division of operator's compartment; Its induction region can not extend to outside the car; Then the outer non-car owner of car can not cause interference to the job procedure of bluetooth communication module naturally, and its safety is also higher, but if such design; Then this car alarm can only be used for igniting, oil circuit and the circuit control system of opening automobile, and it can not be used to control the open and close of car door.
Also have a bit to be exactly, because the False Rate of infrared induction module is high, so it needs other some accessory equipments that its data are revised, and the process of Installation and Debugging is complicated, has increased the cost of Car Burglar Alarm.
