摘要
随着技术的不断发展,安防系统也正由数字化、网络化逐步走向智能化。为了提高室内安防系统的实时性和有效性,设计了一种基于STM32的室内安防监控系统。基于STM32和声源定位技术,设计室内安防监测系统。一方面,结合声源定位技术,通过麦克风阵列采集语音信号,经过信号调理及信号分析后,控制器能有效判断出危险声音源所在位置。另一方面,当家居环境存在危险时,采用STM32控制摄像头自动开启进行跟踪拍摄,并发送报警信息至预设的远程端。系统平时处于断电状态,能耗低。实际测试结果表明,该系统能够快速实现声源定位,并根据声源位置控制舵机和摄像头,将报警信息迅速、有效地发送至远程端,是一种方便且实用的室内安防监控系统,值得推广应用。
With the continuous development of technology,security systems,digitalized and networked,are gradually becoming intelligent.In order to improve real- time performance and effectiveness,an indoor security monitoring system based on STM32 is designed.It is designed based on STM32 and sound source localization technology.On the one hand,the use of sound source localization technology collects voice signals through a microphone array,and after signal conditioning and signal analysis,the controller can effectively locate sound source of danger.On the other hand,STM32 is used to control the camera.In case of danger,the camera can be automatically turned on to track,record and send alarm messages to the preset remote end.Generally,the system is powered off with low energy consumption.Test results show that the system can quickly locate sound source,control the steering gear and camera accordingly,and send alarm information to the remote end in a quick and effective manner.It is convenient and practical for wide use.
