基于VxWorks的无人直升机控制系统设计

组建了一种基于嵌入式实时操作系统VxWorks 平台的无人直升机控制系统，实现远距离无人直升机飞行状态信息传输，接收地面基站命令后完成自主定点飞行任务。主要利用基于优先级的消息队列方法和嵌入式操作系统VxWorks 的信号量与看门狗定时功能实现
多任务间调度，获得飞行状态数据向地面基站传输与自主定点飞行的同步。通过实验飞行，该系统的正确性与可靠性得到了验证。

Abstract: Established a remote control system based on embedded VxWorks system, which can transmit the unmanned helicopter flying real time date to ground control platform and fly form point to point without people control. Message queue based on priority and semaphore and exactitude timing through watchdog which are belonged to VxWorks system are utilized in the monitor system for scheduling multitask, achieve the synchronization with transmitting date and flying without people control. The system exactitude and reliability have been proved through the experiment flying.
