Automobile security anti-theft device

Abstract

The invention discloses an automobile security anti-theft device. The automobile security anti-theft device comprises a tyre pressure detection device, a central controller and a handheld electronic device, wherein the tyre pressure detection device is mounted in a tyre and is connected with the central controller in a wireless communication mode; the tyre pressure detection device detects tyre pressure, temperature and acceleration parameters of the tyre and transmits the parameters to the central controller in a wireless mode; the central controller is mounted in an automobile body and is connected with the handheld electronic device in a wireless communication mode; the central controller is provided with a wireless emitter and a wireless receiver; and the central controller transmits a signal to the handheld electronic device through the wireless emitter and receives a feedback signal of the handheld electronic device through the wireless receiver. The automobile security anti-theft device realizes the security anti-theft function by utilizing the conventional tyre pressure detection device and the data detected by the tyre pressure detection device, so that the research and development cost of the automobile security anti-theft device is greatly reduced, the using cost of the automobile security anti-theft device is reduced and the structure is simpler.

Description

technical field [0001] The invention relates to an automobile safety anti-theft device. Background technique [0002] In the prior art, automobile anti-theft devices can generally be divided into three categories: mechanical, electronic and network. Hook locks, steering wheel locks and gear shift locks, etc. belong to mechanical anti-theft devices, which mainly rely on locking clutches, brakes, gas pedals or steering wheels, and gears to achieve the purpose of anti-theft, such as the disclosed "a car steering wheel anti-theft" application number 200710068532.9 Lock". However, the mechanical anti-theft device is locked in a conspicuous position, and the thieves have made in-depth research on it, so it is very easy to be unlocked and cannot achieve the effect of security and anti-theft. [0003] Plug-in type, button type and remote control type belong to electronic anti-theft devices, which mainly rely on locking ignition or starting to achieve the purpose of anti-theft, and...

AI Technical Summary

Problems solved by technology

[0006] However, the parameters such as tire pressure, temperature and acceleration detected by the tire pressure detection device have not been applied to the anti-theft device, but a complete set of car anti-theft device has been independently developed, which greatly increases the number of automobiles. Research and development costs and use costs of anti-theft devices
