Wireless safety pre-alarming device of vehicle

Abstract

A wireless vehicle safety early warning implement, it comprises the mainframe and the information receiver, the mainframe includes the tone-press detector, detect the infra-acoustic wave inside of the vehicle, create the spring signal of tome-press; the microwave detector create the microwave spring signal by the microwave detective method when somebody in the vehicle; the signal transceiver realize the data exchange with the information receiver; the microprocessor connect and control the switches of the tone-press detector, the microwave detector and the signal transceiver, of them, achieve the status differentiation, enter the early warning state after receive the tone-press spring signal, send the early warning signal to the information receiver and startup the microwave detector, send the alarming signal after receiving the microwave spring signal in the early warning state; the power circuit of the mainframe provide the working power to the mainframe; the information receiver send back the status data to the mainframe after receive the status differentiating data from the mainframe, create the early warning hint after receiving the early warning signal, create the alarming hint after receiving the alarming signal.

Description

technical field [0001] The invention relates to the technical field of automobile anti-theft alarms, in particular to a wireless automobile safety early warning device. Background technique [0002] As a high-tech product, the car's own anti-theft performance is gradually improving. In the prior art, there are various types of car anti-theft devices, among which electronic anti-theft devices are widely used. At present, the popular remote control car alarms, two-way car alarms and GSM car alarms in the domestic market belong to the category of electronic anti-theft devices. [0003] The main principle of the electronic anti-theft device is to install electronic anti-theft equipment on the car to achieve the purpose of monitoring the vehicle and calling the police. Compared with mechanical anti-theft devices, the biggest advantage of electronic anti-theft devices is that they have an alarm function, but false alarms are more common in current electronic anti-theft devices. ...

AI Technical Summary

Problems solved by technology

[0006] At present, the cars produced by foreign auto manufacturers are only equipped with radio frequency ignition safety and anti-theft systems. This system cannot protect the doors and window glass, so it cannot effectively deal with the phenomenon that some thieves in China smash the doors or windows to steal money. , for this reason, it is still necessary to install a high-performance car anti-theft device to improve and improve the safety and value-added of the car
