摘要
为减少城市战伤亡率,提出了一种基于ZigBee和蓝牙技术的红外人体探测系统方案。以星型网络为原型,对系统的探测距离及灵敏度、抗干扰能力、节点功耗、穿透能力进行了测试,做出了定量分析,提出了增大发射功率、使用稳定锂电池、缩小探测距离及角度、部署在关键点、增加关键点路由等改进方法,从而提高系统实战稳定性。测试表明,ZigBee红外人体探测系统功耗低、抗干扰、组网速度快、穿透能力强。半径为6 m,圆心角为80°的扇形是其理想的探测区域。
To reduce the casualty rate of urban warfare, an infrared human detection system program based on ZigBee and Bluetooth technology was proposed. The star network was used as the prototype of the system＇s detection range and sensitivity, anti-interference ability, node power, penetrate was tested the ability to make a quantitative analysis, the increased transmission power, the use of stable lithium batteries, reducing detection distance and angle, deployed in key points, key points to increase routing improvement method to improve the real stability of system. Tests show that infrared human detection system based on ZigBee is low-power anti-interference fast, network speed, strong penetration ability. 6m radius, central angle of 80° is the ideal fan-shaped detection area.
