基于单一的振动传感器的防盗报警系统很难全面准确地反映周围的监测环境是否安全,因此误判率较高。该系统采用多普勒传感器、振动传感器、霍尔传感器、红外传感器和位移传感器对周围环境信息进行监测,通过多传感器D-S融合算法对几个传感器子系统的信号进行分析判断;若通过检测分析,信号类型属于报警信号4种类型之一或之中的几种,则会产生报警指令,触发防盗报警系统进入报警状态。该系统在报警状态下,可以实现给用户手机发送报警信息,并且根据用户指令实现对于车内环境的实时视频监控的功能。该系统基于Linux平台实现视频监控数据的采集和传输,具有误报率低,可靠性强,稳定性高等优点。
Burglar alarm system based on a single vibration sensor is difficult to fully and accurately reflect the surrounding monitoring environment is safe, so a higher false positive rate. The system uses the Doppler sensor, the vibration sensor, the Hall sensor, the infrared sensor and the displacement sensor to monitor the surrounding environment information. Through the multi-sensor DS fusion algorithm, the signals of several sensor subsystems are analyzed and judged; if the detection and analysis, If the signal type belongs to one of the 4 types of alarm signals or some of them, an alarm instruction will be generated to trigger the burglar alarm system to enter the alarm status. The system in the alarm state, you can send to the user to send alarm messages, and in accordance with user instructions for real-time video monitoring of the car environment functions. The system based on Linux platform to achieve video surveillance data acquisition and transmission, with low false alarm rate, reliability, high stability and so on.
