摘要
针对助航灯光的故障发现主要靠人工巡视的现状,使用MC9S08GT60单片机和nRF905射频芯片设计了一个助航灯光监测系统。设计了无线传感器网络节点,采用了DSR路由协议,实现了传感器节点的自组网。该系统可以准确检测出助航灯光亮度异常、灯具断芯和隔离变压器二次侧开路等故障,可以帮助工作人员及时发现灯具故障并及时维护,从而保障飞机安全起降。
Based on microcontroller MC9S08GT60 and transceiver nRF905,a airfield lights supervision system is designed to change the situation in which the detection of the airfield lights faults only relies on manual work.A kind of wireless sensor network node and DSR routing protocol are designed,and all the sensor nodes are composed to a self-organized network.With the help of this system,some troubles such as the abnormity of the lightness,the open-circuit of the lampwick and the isolated transformer′s secondary circuit opening can be precisely detected and then be maintained promptly by the airport maintenance personnel,hence,the safety of airplane taking off and landing can be guaranteed.
