天幕靶是一种用来探测飞行目标到达空间某一预定位置时刻的光电设备.在靶场测试领域中,随着测试技术的日益网络化,一种具有网络接入功能的天幕靶信号处理装置,保证了更大测试系统的正常运转.基于ZigBee自组网以及无线控制原理,提出了一种网络接入设计方案,详细介绍了ZigBee原理以及软件设计方案,设计出一种天幕靶信号处理装置.分析结果表明:天幕靶信号处理装置的设计可以实现200 m的通信距离,接入点可达到16个,同时无线网络的接入使得其测试精度达到0.5μs,并且可以远程监控各个设备的运行状态.%Sky screen is a kind of photoelectric devices detecting the times of a flying object reaching a certain place. With test techniques becoming more network-based, a kind of sky screen signal processing device can ensure the normal operation of a larger testing system in the proving ground. A kind of design project of network access is proposed here, based on ZigBee and the principle with wireless control. After the introduction of the ZigBee principle and software design project, the design of a kind of sky screen signal processing device is presented. The analytical results show that the device can reach 200 m communication distance and have the ability of 16 access point. At the same time, the system can reach 0. 5 μs accuracy and monitor the operational state of all devices.
