Intelligentized body capacitance multi-point touch induction antitheft device and antitheft method

Abstract

The invention discloses an intelligentized body capacitance multi-point touch induction antitheft device which is composed of a master controller and a plurality of capacitance touch inductors. A single-chip microcomputer chip and a detection control circuit are arranged in the master controller, capacitive body induction chips with an automatic correction function are adopted in the touch inductors, the capacitive body induction chips are small in appearance and can be mounted at any position of the back face of nonmetal matter in a motor vehicle cab according to the type of a motor vehicle and the operation habits of a vehicle owner, and the elusive performance is strong. An oiling diagram of the motor vehicle can be disconnected in the antitheft state, a driver needs to carry out unlocking through the touch inductors, the touch inductors can be selected to be mounted, the unlocking mode of the combined touch and sequential touch of a single point and multiple points is formed, multiple unlocking combinations exist, and passwords are hard to crack. The device is suitable for fuel oil motor vehicles such as small vehicles and motorcycles, and has the advantages that the antitheft performance is high, and the unlocking operation is convenient, simple and intelligent. The invention further discloses an antitheft method.

Description

technical field [0001] The invention relates to the field of vehicle anti-theft technology, in particular to an intelligent body capacitive multi-touch sensor anti-theft device and anti-theft method suitable for automobiles, motorcycles and other fuel vehicles. Background technique [0002] As the number of motor vehicles increases year by year, how to increase the anti-theft performance of motor vehicles has become a topic of concern. Now the popular motor vehicle anti-theft devices on the market generally include mechanical locks, GPS network anti-theft locks, switch-type built-in locks, and digital electronic locks. Wait for a few categories. The mechanical lock uses a mechanical method to lock the steering wheel, brake pedal, wheels and other positions. It has a simple structure and is cheap, but it is easy to be unlocked violently, and it only prevents theft and does not call the police. GPS network anti-theft lock is a better anti-theft system, but it is expensive, an...

AI Technical Summary

Problems solved by technology

The mechanical lock is to lock the steering wheel, brake pedal, wheel and other positions mechanically. It has a simple structure and is cheap, but it is easy to be unlocked by violence, and it only prevents theft and does not call the police.

GPS network anti-theft lock is a better anti-theft system, but it is expensive, and the existence of jammers will make the anti-theft system invalid

Switch-type built-in lock is cheap and easy to install, but the position of the switch is easy to be found, and the anti-theft performance is not high

The following types of digital electronic locks are commonly used: remote control type, many jammers on the market can prevent your anti-theft device from being locked, or use a decoder to read your decoded data to unlock, the anti-theft performance is not high

[0003] RFID wireless radio frequency inductive locks use a unique unlocker to unlock, and the same disadvantage as the remote control type. If the unlocker is lost, it will be very troublesome. It will take a certain amount of time to re-match one, which brings inconvenience to the use. inconvenient

For fingerprint locks, the recognition time before starting the car is long, and the recognition rate for dirty fingers, wet fingers, and dry fingers is very low. Some fingerprint locks can also be unlocked with the fingerprint image of the car owner.

There is also a single-point touch built-in lock commonly used on motorcycles. It needs to be connected with metal to form a touch area, but this touch area is not high in concealment, easy to be cracked, and has low sensitivity, which is easily affected by water droplets, small animals, False triggering caused by mobile phone signal and other influences
