Abstract

The utility model discloses a password-control burglary prevention device for a vehicle, which includes a key-turning detection device, a password signal inputting device and a burglary prevention controller. The key-turning detection device sends pulse signals through the rotation of an original car key in an ignition key lockhole; the password signal inputting device is used for recording and checking pulse signals sent by the key-turning detection device and outputting pulse signals to the burglary prevention controller; and the burglary prevention controller is used for analyzing and judging pulse signals and controlling whether to open a vehicle starting circuit and an oil pump circuit or not according to the judging results. The password-control burglary prevention device for the vehicle has the advantages as follows: the vehicle can be started only in the manner as follows: a user knowing the set passwords in the burglary prevention controller inputs starting passwords by turning the key in the ignition key lockhole and the set passwords are matched with the input passwords, therefore, the car missing phenomenon is effectively avoided.

Description

A kind of vehicle cryptographic control anti-joyride device

Technical field

The utility model relates to a kind of alarms and security systems for automobiles that is used for cipher control.

Background technology

Alarms and security systems for automobiles of the prior art is generally mechanical type, need be on automobile installation direction dish latching device, and with firm be hooked together lock bearing circle and a brake pedal or a tire of system.The shortcoming of mechanical alarms and security systems for automobiles is to use traditional mechanical key to come start a car, in case key loss is prepared by the people, will give car stealer's opportunity.

The utility model content

At the problem that prior art exists, the utility model provides a kind of alarms and security systems for automobiles that starts by former car key of rotation and then Control of Automobile in the ignition key lockhole.

For achieving the above object, the utility model vehicle cryptographic control anti-joyride device, comprise key turns detecting device, code signal input media and anti-theft controller, the key turns detecting device links to each other with the code signal input media, the code signal input media links to each other with anti-theft controller, and the key turns detecting device rotates in the ignition key lockhole by former car key and sends impulse singla; The code signal input media is used for impulse singla record that the key turns detecting device is sent, checks, and impulse singla is outputed to anti-theft controller; Anti-theft controller is used for the pulse signals analysis and judgement, and motor start circuit and oil pump circuit are opened or do not opened in control according to judged result.

Further, described anti-theft controller links to each other with a warning device.

Vehicle cryptographic control anti-joyride device of the present utility model, the user needs according to password fixed in anti-theft controller, input the automobile starting password by screw key in the ignition key lockhole, having decided password and input password coupling just can successful start a car, even automobile key is lost, the car stealer does not know that the key turns input mode also can't drive away automobile, can effectively stop to lose the car phenomenon.

Description of drawings

Fig. 1 is the structural representation of the utility model alarms and security systems for automobiles;

Fig. 2 is the workflow diagram of the utility model alarms and security systems for automobiles.

The specific embodiment

As shown in Figure 1, the utility model vehicle cryptographic control anti-joyride device, comprise key turns detecting device 2, code signal input media 3 and anti-theft controller 4, key turns detecting device 2 links to each other with code signal input media 3, code signal input media 3 links to each other with anti-theft controller 4, ignition key is locked the switch that 1 essence is a Control of Automobile circuit, ignition key lock 1 is outwarded winding or is revolved when closing, be equivalent to switch connection is disconnected, institute's connection circuit has electricity or power failure, obtain 1 or 0 pulse, the pass key of outwarding winding for N time, rotation detecting device 2 sends the N subpulse, 3 pairs of above-mentioned N subpulse records of code signal input media, check, impulse singla is sent to anti-theft controller 4, anti-theft controller 4 is according to fixed code signal and whether the comparison of this impulse singla mates by relay 5 Control of Automobile start-up circuits and the oil circuit circuit is opened or pass through warning device 6 warnings.

Wherein fixed code signal figure place and the password of each all can be set up on their own by owner in the anti-theft controller 4, the close stance turn of automobile key from the ignition key lock 1 is to open position, counting is 1, repeat continuously in short time to count several times to several, pause then and carry out the input of next bit numeral slightly for a long time, the password of input conforms to and can normally start automobile to the anti-joyride device release with fixed password.

Be illustrated in figure 2 as the operating process of the utility model anti-joyride device, owner turn key in the ignition key lockhole sends impulse singla and carries out the password input, and judge whether input password and fixed password mate, if two passwords coupling automobile can normally start, can not trigger the warning device warning if match.

Alarms and security systems for automobiles of the present utility model, is password input mode with key in ignition key lockhole transfer action, and then judge whether to start automobile, have only owner to know the unlocking pin of anti-joyride device, even automobile key is lost, other people also can't start a car, has effectively stopped to lose the car phenomenon.

It is to be noted and any pro forma distortion of making according to the specific embodiment of the present utility model all do not break away from the scope that spirit of the present utility model and claim are put down in writing.

Claims

1. a vehicle cryptographic is controlled anti-joyride device, it is characterized in that, comprise key turns detecting device, code signal input media and anti-theft controller, the key turns detecting device links to each other with the code signal input media, the code signal input media links to each other with anti-theft controller, and the key turns detecting device rotates in the ignition key lockhole by key and sends impulse singla; The code signal input media is used for impulse singla record that the key turns detecting device is sent, checks, and impulse singla is outputed to anti-theft controller; Anti-theft controller is used for the pulse signals analysis and judgement, and motor start circuit and oil pump circuit are opened or do not opened in control according to judged result.

2. vehicle cryptographic control anti-joyride device as claimed in claim 1 is characterized in that described anti-theft controller links to each other with a warning device.
