摘要
首先阐述了无人机遥控遥测系统的工作原理和特点,然后对实时控制系统在Windows下的几种常用精确定时方法进行介绍,最后设计一种多线程高精度定时器,实现遥控指令的精确定时发送,遥测数据的实时接收处理;通过现场调试,验证了该定时器的高精度性能,很好地完成了无人机地面控制站和自动驾驶仪之间的通信任务。
Firstly, the work principle and characteristics of UAV remote control and test system are narrated, secondly, several methods on usually adopted precise timing of real-time control systems under Windows are introduced. Finally, a kind of high precise timer with multithreading was designed, then assigning instructions of remote control to the automatic pilot is realized by precise timing, at the same time obtaining and disposing the remote data from the automatic pilot with real time. After practically testing, experiments validate the high precise performance of the timer, the task between the ground control system and the automatic pilot is fulfilled with satisfaction.
