无线传感器网络中的被动式红外传感器模型研究

Research of passive infrared sensor model for wireless sensor networks

针对公共安全的需要,利用无线传感器网络系统进行区域监控已然成为趋势。通过对系统的物理结构分析提出了一种被动式红外传感器模型。该模型对配备被动式红外传感器的无线传感网络的系统设计具有指导意义。传感器节点的测试以及实时系统的试验验证了模型的可靠性。

For public security, wireless sensor networks have been widely applied in monitoring public area or target. After in-depth structure analysis, a passive infrared sensor （PIR） model was presented. This model provides some useful suggestion for the wireless sensor networks system design that is equipped with PIR sensor. The sensor test and real-time system experiment validate the reliability of this model.
