摘　　要：为提高停机坪保障设备(包括航班保障车辆和廊桥等)运行安全及效率,提出了一种利用Linux平台及其驱动模块相结合的嵌入式停机坪保障设备状态监测平台的设计方法。借助sysfs组织机制、NETLINK异步通信机制、shell脚本、udev设备管理机制和UEVENT事件等Linux机制,并通过在监测平台上建立采集设备属性文件映像的方式,实现通过访问本地属性文件映像访问远程设备数据采集节点的物理传感器获得停机坪保障设备的工作状态和参数信息。在调试运行中,使得监测网络中传感器以结构可视化方式呈现在监测平台上,且监测平台具有远程实时在线访问停机坪保障设备上传感器的能力。To improve the operational safety and efficiency of the apron support equipment （including flight support vehicles and bridges, etc）,combining Linux platform with its driver modules ,achieves parameters that making serious impacts on the safety of the aircraft to be remote monitored.Depending on Linux mechanisms including sysfs organizational mechanism, NETLINK asynchronous communication mechanism, shell scripts, udev devices＇ management mechanism and UEVENT events and so on,images of sensors connected to remote devices are mapped locally. Through these images,the monitoring station obtains remote physical sensors＇outputs in the same access mode when getting itself sensors＇outputs.In debugging and running,the sysfs files＇images can make the whole monitoring network in a structured and visual presentation in the monitoring station, and more important is that the station has the realtime and online access to the remote device sensors on the apron support equipment in monitoring network.
