摘　　要：为解决当无人机受到干扰时,飞行数据采集异常情况从而导致无人机无法正常工作的情况,文章提出了一种适合无人机系统使用基于VxWorks并行时钟工作特性的无人机飞行数据抗干扰方法;并给出关键技术的研究途径和工程实现方法;经理论分析,本方法有效的解决无人机飞行数据的抗干扰问题;最后通过飞行实验数据表明本方法抗干扰性能良好,并且不会对无人机系统的硬件设计和实时性产生影响,可应用在无人机系统设计中。In order to solve the problem that the UAV could not fly and work normally because the flight data acquisition is abnormally when the UAV is interfered, the paper shows the anti--interference method in UAV flight data based on the character of VxWorks＇ timer technology by analyzing the UAV flight data and traditional anti--interference method. The paper describe the method how to research and realize the key technology. Through theoretical analyzing and comparing the result of UAV flight data, it shows that the method could solve the anti--interference situation effectively without changing the hardware design and the real--time of the UAV system and can he applied in UAV design.
