Multifunctional automobile anti-theft alarm

Abstract

The invention relates to an automobile safety accessory, and particularly relates to a multifunctional automobile anti-theft alarm. The multifunctional automobile anti-theft alarm comprises a power supply, a fatigue driving testing device, an alcohol detecting device, a sensing device, a fingerprint lock, a single chip microcomputer, an audible alarm device and an automatic ignition locking device, wherein an anode and a cathode of the power supply are respectively connected with ports P1.0 and P2.0 of the single chip microcomputer; the fatigue driving testing device is connected with an input port P1.1 of the single chip microcomputer, the alcohol detecting device is connected with an input port P1.2 of the single chip microcomputer, and the audible alarm device is connected with an output port P2.1 of the single chip microcomputer; the sensing device is connected with an input port P1.3 of the single chip microcomputer, and the automatic ignition locking device is connected with an output port P2.4 of the single chip microcomputer; the output end of the fingerprint lock is connected with an input port P1.5 of the single chip microcomputer, and the input end of the fingerprint lock is connected with an output port P2.5 of the single chip microcomputer. By using the scheme of the multifunctional automobile anti-theft alarm, the situations that an automobile is stolen, a drunk driver drives and a driver drives when the driver is tired are prevented.

Description

technical field [0001] The invention relates to automobile safety accessories, in particular to a multifunctional automobile anti-theft device. Background technique [0002] With the development of the times, the number of cars is also increasing day by day. At the same time, car theft incidents are also increasing. Therefore, car alarms are almost a must-have car safety accessory for every car, but the current car alarms There are mainly mechanical anti-theft and electronic anti-theft. Electronic anti-theft is to achieve the purpose of anti-theft by locking the motor and circuit of the car; while mechanical anti-theft is to lock the ignition device on the car by using a simple mechanical principle so that it cannot function to achieve the purpose of anti-theft; although electronic anti-theft is better than mechanical anti-theft, it still cannot achieve the purpose of anti-theft very well, and the current car anti-theft device has a single function and cannot greatly meet th...
