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...
