Abstract
The utility model discloses an automobile anti-theft device and relates to the technical field of automobiles. The utility model aims to solve the problem that the conventional automobile anti-theft lock can be prepared, copied and decoded, is low in safety, makes an automobile owner impossible to defend burglar effectively and brings great mental pressure and economic loss. A fingerprint identification sensor of the automobile anti-theft device consists of a slide fingerprint identification chip and a PS1802 which are connected; the signal output/input data bus end of the fingerprint identification sensor is connected with the fingerprint signal output/input end of a digital signal processor (DSP) chip; the data output/input bus of a FLASH program storage and the data output/input bus of a static random access memory (SRAM) data storage are connected with the data output/input end of the DSP chip; and the result control signal output end of the DSP chip is communicated with an engine starting control signal of a central control computer in an automobile. The automobile anti-theft device can realize fingerprint identification start, has functions of preventing preparation, copy, interference and decoding, and has the advantages of convenience and safety in use, simple structure, and low manufacturing cost.
Description
Technical field
The utility model relates to automobile technical field.
Background technology
Existing alarms and security systems for automobiles is the anti-theft column lock of band key or remote controller mostly, and because of these can be prepared, duplicate and crack by the people, safety is low.Make the car owner hard to guard against, bring very big stress and economic loss.
Summary of the invention
The purpose of the utility model provides a kind of alarms and security systems for automobiles, can prepared, duplicate and crack by the people in order to solve existing automobile anti-theft lock, and safety is low, makes the car owner hard to guard against, brings the very big stress and the problem of economic loss.
Described purpose realizes through following scheme: described a kind of alarms and security systems for automobiles, form by fingerprint Identification sensor, dsp chip, FLASH program store, SRAM data memory;
Fingerprint Identification sensor connects PS1802 by slide fingerprint identification wafer and forms; The signal input-output data bus end of fingerprint Identification sensor is connected with the fingerprint signal I/O of dsp chip; The data output input bus of FLASH program storage, the data output input bus of SRAM data storage all are connected with the data I/O of dsp chip, and the output of control signal as a result of dsp chip is communicated with the engine start control signal end of middle control computer in the automobile.
The utility model can realize that fingerprint recognition starts, and has anti-preparation, anti-copy, interference protection, the anti-function that cracks, and has safe, simple in structure, cheap advantage easy to use.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
The specific embodiment one: as shown in Figure 1, it is made up of fingerprint Identification sensor 1, dsp chip 2, FLASH program store 3, SRAM data memory 4;
Fingerprint Identification sensor 1 connects PS1802 by slide fingerprint identification wafer and forms; The signal input-output data bus end of fingerprint Identification sensor 1 is connected with the fingerprint signal I/O of dsp chip 2; The data output input bus of FLASH program storage 3, the data output input bus of SRAM data storage 4 all are connected with the data I/O of dsp chip 2, and the output of control signal as a result of dsp chip 2 is communicated with the engine start control signal end of middle control computer 5 in the automobile.
Principle of work: fingerprint Identification sensor 1 is arranged on (not noticeable) dorsad of bearing circle, and during initialization, the car owner can import 5 different fingerprints as model; Automatically detect driver's fingerprint when starting automobile later at every turn, as the situation that do not match, this device middle control computer 5 in automobile sends request, and behind the certain hour, car door automatically locks, and drive wheel is locked, and starts warning device, has reached theft-proof effect.
