用于周界入侵报警的红外—超声波无线传感器网络节点设计

Design of infrared-ultrasonic wave WSNs node for perimeter intrusion alarm

为了提高周界入侵探测的网络化、自动化水平,有效覆盖传统入侵探测的监控盲区,将无线传感器网络(WSNs)技术应用于周界入侵报警,设计了一种红外—超声波联合周界入侵报警节点和报警软件。节点采用热释电红外传感器与超声波传感器相结合的方式组成前端探测模块,并基于GAINz平台设计实现了无线通信和数字处理单元。通过实验室测试,传感器节点能够成功进行周界入侵报警,并有效消除误差,解决了单一传感器因自身缺陷而出现的漏报误报问题。

In order to improve networked and automatic level of perimeter intrusion detection and cover dead area of monitoring of traditional intrusion detection effectively,WSNs technology in perimeter intrusion alarm a kind of infrared-ultrasonic wave joint perimeter intrusion alarming node and software is designed.The node uses method of combination of pyroelectric infrared and ultrasonic wave sensors to comprise frontier detective module,and realize wireless communication and digital processing unit based on GAINz.Through test in laboratory,sensors nodes can realize perimeter intrusion alarm successfully,eliminate errors effectively,and solve problem of false and missing alarm caused by own defect of single sensor.
