Intelligent automobile anti-theft system

Abstract

The invention relates to the technical field of intelligent automobiles, in particular to an intelligent automobile anti-theft system. The intelligent automobile anti-theft system comprises an automobile terminal and a mobile terminal, the automobile terminal comprises an infrared pyroelectric sensor, an anti-theft module, a GPS positioning module, a short message sending module, an electronic lock and a first controlling module; the infrared pyroelectric sensor is used for detecting whether a person exists in a certain range of a vehicle body or not, the anti-theft module is used for detecting the state of an automobile to judge whether external force invading exists or not, and the GPS positioning module is used for detecting the position of the automobile to obtain geographic position data of the automobile; the short message sending module is used for sending alarming information and positioning information to the mobile terminal in a short message mode, the electronic lock is used for opening or closing of an automobile door, and the first controlling module is used for receiving signals collected by the infrared pyroelectric sensor and the anti-theft module and controlling the electronic lock, the GPS positioning module and the short message sending module to work; the mobile terminal comprises a short message receiving module, a displaying module and a second controlling module, the short message receiving module is used for receiving a short message sent by the automobile terminal, the displaying module is used for displaying the short-message-type alarming information and positioning information, and the second controlling module is used for controlling the short message receiving module and the displaying module to work.

Description

technical field [0001] The invention belongs to the technical field of smart cars, and in particular relates to a smart car anti-theft system. Background technique [0002] With the improvement of living standards, cars are becoming more and more popular in people's lives. At present, the more commonly used car anti-theft technology relies on the car anti-theft device with remote control function. After the owner locks the vehicle, when the vehicle encounters an abnormal start, the remote control alarm signal is transmitted to the car anti-theft device to alarm the owner. However, the transmission frequency of the existing remote control is usually below 1GHz, which limits the transmission of the alarm signal to a very long distance. Moreover, due to the poor penetration of frequencies below 1GHz, the occlusion of buildings on the transmission path will cause the signal to fail at all. can not receive. Therefore, in the case of a long distance or a building blocking betwee...

Problems solved by technology

However, the transmission frequency of the existing remote control is usually below 1GHz, which limits the transmission of the alarm signal to a very long distance. Moreover, due to the poor penetration of frequencies below 1GHz, the occlusion of buildings on the transmission path will cause the signal to fail at all. can not receive

Therefore, in the case of a long distance or a building blocking between the car and the owner, the various limitations of the existing anti-theft signal transmission technology make it unreliable to obtain the anti-theft status of the car through the remote control.
