Gravity acceleration inductive type automobile theft protection installation

Abstract

The invention relates to a vehicle anti-thief device of gravitational acceleration induction, which mainly utilizes the gravitational accelerometer on the vehicle to actively detect the change of gravitational acceleration. When the change of gravitational acceleration detected by the gravitational accelerometer is over a safety valve of preset gravitational acceleration change, it can send a relative abnormal signal to make the vehicle-carrying anti-thief host computer can control at least one alarm device to send alarm.

Description

technical field [0001] The invention relates to an automobile anti-theft device, in particular to a gravitational acceleration induction type automobile anti-theft device. Background technique [0002] It is known that in order to prevent the car from being stolen or accidents, car owners usually install an anti-theft device for the car. When the car owner is not in the car, the anti-theft device can be activated and use various detectors to detect abnormal conditions. [0003] Therefore, if the vehicle is abnormal, such as when the vehicle is invaded, the detector will sense and trigger the car anti-theft device. Most of the traditional car anti-theft devices are eye-catching by the ear-piercing whining sound, which can make the thief escape and fail to succeed, or let the car owner rush back to the vehicle parking place to care after hearing the sound of the anti-theft device. abnormal situation.

Most of the traditional car anti-theft devices are eye-catching by the ear-piercing whining sound, which can make the thief escape and fail to succeed, or let the car owner rush back to the vehicle parking place to care after hearing the sound of the anti-theft device. Abnormal situation

[0004] However, although the beeping function of the traditional car anti-theft device can effectively deter theft, the range of the beeping sound is limited. The car owner may not be able to hear the beeping sound from the anti-theft device, and often misses the opportunity for rescue.

In addition, or when the car is towed, even if the anti-theft device keeps beeping along the road, it is not easy for the car owner in the distance to be aware of the abnormal condition of the car, or even unable to track it. Only when the car owner returns to the parking place will he find out The car has been towed away

Many of the above situations are due to the fact that the known anti-theft device does not have the function of proactively notifying the car owner. Not only can it not completely guarantee the safety of the vehicle and notify the car owner in real time, but it will also cause noise problems to the surroundings, which is not very ideal.
