Multi-sensor fused comprehensive car alarm system

Abstract

The invention relates to a multi-sensor fused comprehensive car alarm system which comprises a multi-sensor fusion module, a central processing module, a wireless communication module, a GPS (global position system) positioning module and an alarm device, wherein the multi-sensor fusion module is connected with the central processing module; the central processing module is connected with the alarm device and the GPS positioning module, and carries out interaction with a mobile phone of a car owner by the wireless communication module; the multi-sensor fusion module adopted by the invention comprises a microwave Doppler sensor, an acceleration sensor, a pyroelectric infrared sensors and a Hall switch element, so that the multi-sensor fusion module can carry out all-round monitoring on carinformation and cope with various theft means, thereby improving the security and reliability of the system, and reducing the rate of error alarming; the alarm device comprises an antiriot spray device, so that the car owner can remotely control a thief and subdue a thief on site; the wireless communication module supports video transmission, picture transfer and short message supervisioning; andmeanwhile, the car alarm system also has the GPS positioning module, thereby facilitating the position search of a car.

Description

technical field [0001] The invention relates to an automobile anti-theft system, in particular to an integrated automobile anti-theft system with multi-sensor fusion. Background technique [0002] With the development of network technology, the car anti-theft system based on remote monitoring is rapidly becoming mature. However, there are various problems in the car anti-theft systems on the market, and the more prominent ones are: 1. The sensor is single, it is difficult to deal with various theft methods, and the false alarm rate is high, causing unnecessary troubles to users; 2. The previous car The anti-theft system lacks effective means to subdue the thieves on the spot. When the police or car owners arrive at the scene, the thieves have often fled; 3. The car anti-theft system based on remote video surveillance relies on 3G network coverage. In areas without 3G networks, the system is difficult to work normally. Work. Contents of the invention [0003] The present ...
