扑翼式微型飞行器的风洞试验动态数据采集和处理

介绍了扑翼式微型飞行器的虚拟仪器测控系统结构,以及为避免多线程中死锁的关键问题,建立基于安全队列的多线程技术的动态实验测量系统.以微型飞行器风洞动态实验为对象,解释了基于安全队列的多线程技术应用于动态测控实验的优势.通过某扑翼式MAV进行吹风试验和频率谱计算,进一步验证了动态测量的正确性.

The dynamic data acquisition and analysis of flapping wing MAV

This article presents the structure of the virtual instrument measurement and control system of flapping wing-MAV(Micro Air Vehicle).A measurement system of dynamic experiments has been developed by using the multithreads technique based on safety queue for avoiding deadlocks,which is the key problem of multithreads.Moreover according to the object of the dynamic experiment of micro air vehicle,the advantages of the multithreads techniques based on safety queue applied in the dynamic measurement and control experiments are explained.Through testing a kind of flapping-wing MAV in wind tunnel,and calculating the sampling spectrum of some experiment results,the correctness of dynamic measurement is validated.
