Based on ZigBee Ad-hoc network airfield lighting communication function test

传统助航灯光系统采用有线连接,布线复杂、麻烦,施工量大,施工周期长,智能化程度低、可扩展性差、调光系统受损后恢复慢、隐蔽性差、不适合做战时之需等缺点。设计了基于ZigBee自组网机场助航灯硬件架构和软件管理。同时对系统的控制节点进行实验测试,测试方案分为4种：无功放无中间路由节点、无功放有中间路由节点、有功放无中间路由节点和有功放有中间路由节点。通信测试结果表明ZigBee节点间的无线通信距离可拓展到1.5km,节点信号接收强度接近理论值。系统设计的节点能够满足系统的网络覆盖范围要求,并可以实现网络的自组织和自愈功能,保证了系统通信的稳定性,提高了网络的健壮性和抗干扰性。

The traditional navigation lightings system was wired connections、wiring complicated、large amount of construction、long construction period、low intelligence、poor scalability、dimming system slow recovery after damaged、poor concealment and not suitable for war.Considering these shortcomings,the design is based on ZigBee Ad-hoc airport navigation lighting hardware architecture and software management function.At the same time,the control node of the system is tested experimentally.And the test program is divided into four kinds：No power amplifier without intermediate routing node,No power amplifier with intermediate routing node,Power amplifier without intermediate routing node,Power amplifier with intermediate routing node.The test results show：the wireless communication distance between ZigBee nodes can be extended to 1.5 km,and the node signal reception strength is close to the theoretical value.The system design nodes realized the network self-organization and self-healing function under the network coverage requirements.It ensures the stability of system communication and improves the network robustness and anti-interference.
