Identity of automobile identification Car Burglar Alarm
Technical field
The utility model relates to a kind of identity of automobile identification Car Burglar Alarm, is mainly used in after automotive engine stops the automobile safety theft-proof system self-opening; When automobile starting,, realize that a key starts, and prevents that vehicle is stolen to driver identity identification authentication.
Background technology
The anti-joyride device of modern automobile is multifarious, mainly be divided into four big classes: mechanical type, electronic type, chip type and network type, four respectively have characteristics, quality is respectively arranged, the antitheft employing of network type GPS location technology wherein, can understand the residing position of current vehicle at any time, but all will collect service charge every year, cost is too high.Traditional mechanical type is actually a kind of mechanical locking, comprises steering-wheel lock and gear lock two big classes.Electronic type is antitheft to be one of anti-joyride device that is most widely used at present, be divided into two kinds of one way communication and two way communications, but its maximum shortcoming is, when the car owner uses remote controller switch car door, the password that car thief can nearby send with receiver of remote-control sytem or scanning device intercepting on-air radio electric wave can crack automotive theft proof system by demoder again.Chip type digital anti-theft device is the emphasis of present car alarm development, and its groundwork is to pin automotive engine, circuit or oil circuit, can't start vehicle under the situation of no RFID chip key, or starts behind the vehicle interior auto shut down in three seconds.At present, the chip type digital anti-theft developed into for the 4th generation, possessed special information diagnosis function, can be when reading the key security information, can also understand the history information of this Car Burglar Alarm, have elementary intelligent characteristics, its unique REID (RFID), can discern its identity automatically when guaranteeing chaufeur near vehicle, chaufeur can start anti-joyride device during away from vehicle automatically, the ratio of performance to price is good, therefore has better anti-theft than other anti-joyride device, has represented the main developing direction of car alarm.
Summary of the invention
Technical matters
Existing car alarm major part is an electronic type, mainly not having key gate inhibition mode with wireless remote control enters, because most Car Burglar Alarms have adopted rolling code and frame hopping encryption technology, but reliability is not fine, and enciphered message is propagated in a bigger open space, information leakage is very easily illegally stolen, so anti-theft effect is also unsatisfactory.How unique authentication information of validated user is deposited among the chip, closely read automatically by REID (RFID), eliminate the safety precaution leak that occurs in the existing automobile starting process, the utility model is puted forth effort the problem that will solve just.
Technical scheme
For solving the problems of the technologies described above, the utility model proposes a kind of identity of automobile identification Car Burglar Alarm, its novel part is, takes the lead in a key start-up technique and the secure authentication technology of automobile are combined, and has realized the safe antitheft of chip level.Specifically, earlier the antenna induction device is installed in the shelter in the car, identity information with validated user writes in the identification key chip in advance again, and this chips welding is encapsulated in the identification key pcb board, at last identification key pcb board is embedded in the handle of identification key, this identification key is carried by chaufeur, during driving, chaufeur is earlier with the close antenna induction device of identification key, by REID (RFID), the antenna induction device can be with the identity information of reading automatically in the key chip, and this information transfer handled to main control system identification, when being confirmed to be validated user, the main control system automatic unlocking starts button, and this moment, button was effective, after chaufeur is pressed the startup button, can open automobile required ON power supply of when work, the ACC power supply is also finished the automotive ignition action, realizes the button start-up operation of automobile.This shows, after the button startup of automobile and identity information are discerned both combinations, realized the digital anti-theft between the chip-scale, owing to be the data transmission of (in the 12cm) closely, car thief can't be from aerial intercepting password, also can't crack, thereby improve the safety that the distribution of automobile authentication information is transmitted greatly, improve antitheft grade by wireless scan mode.
