Motor vehicle anti-theft system

Abstract

The invention provides a motor vehicle anti-theft system. The system comprises a motor vehicle key and a motor vehicle lock, wherein the motor vehicle key and the motor vehicle are in insertion contact; the motor vehicle lock comprises a master controller, a memory, a biological characteristic comparison unit, an engine startup control unit and a motor vehicle keyhole, wherein the shape of the keyhole is matched with that of the motor vehicle key; two sides of the keyhole contacted with the motor vehicle key are connected with the anode and the cathode of a motor vehicle accumulator respectively; a raised metal part is formed in the middle part of two sides of the keyhole contacted with the motor vehicle key, and is connected with the master controller; the motor vehicle key comprises a memory and a master controller; biological characteristic information the same as that stored in the memory of the motor vehicle lock is stored in the memory of the motor vehicle key; two sides of the motor vehicle key are contacted with the keyhole of the motor vehicle lock respectively; a depressed structure is formed on the top end of the two sides of the motor vehicle key, and a metal part inside the depressed structure is in data connection with the master controller of the motor vehicle lock.

Description

technical field [0001] The invention relates to the field of motor vehicle anti-theft, in particular to a motor vehicle anti-theft system. Background technique [0002] For a long time, the anti-theft problem of motor vehicles has always been a concern of car owners. Although people have taken various anti-theft measures, they are always hard to guard against, and motor vehicle theft still occurs from time to time; at present, many motor vehicle anti-theft Although there are many anti-theft methods, they can generally be summarized into the following categories: mechanical anti-theft, electronic anti-theft, and intelligent anti-theft; mechanical anti-theft is the simplest and cheapest method on the market. Its principle is simple and the price is cheap, but its The anti-theft ability is the weakest; electronic anti-theft is to install electronic anti-theft settings on motor vehicles to achieve the purpose of monitoring vehicles and alarming, but there may be false alarms; in...

[0002] For a long time, the anti-theft problem of motor vehicles has always been a concern of car owners. Although people have taken various anti-theft measures, they are always hard to guard against, and motor vehicle theft still occurs from time to time; at present, many motor vehicle anti-theft Although there are many anti-theft methods, they can generally be summarized into the following categories: mechanical anti-theft, electronic anti-theft, and intelligent anti-theft; mechanical anti-theft is the simplest and cheapest method on the market. Its principle is simple and the price is cheap, but its The anti-theft ability is the weakest; electronic anti-theft is to install electronic anti-theft settings on motor vehicles to achieve the purpose of monitoring vehicles and alarming, but there may be false alarms; intelligent anti-theft is generally established on the wireless communication network, and the device is controlled by mobile phones Based on the control equipment on the motor vehicle to achieve the purpose of remote monitoring the theft of the motor vehicle, the owner can instantly know the situation of the theft of the motor vehicle through the portable mobile terminal, but because it depends on the wireless communication network, when the wireless network fails or When the network coverage is lost, the motor vehicle anti-theft will no longer work, which is an unacceptable situation for motor vehicle anti-theft, and then the use of biological anti-theft technology has occurred, such as Chinese invention 200410054717.0 which discloses a...
