摘　　要：大气数据的采集对于小型无人旋翼机飞行的控制具有关键性的作用,针对小型无人旋翼机的飞行控制需求,利用数字式MEMS传感器和TMS320F28335芯片设计了一种装载于小型无人旋翼机上双采集装置的大气数据采集系统.通过传感器采集数据,实时解算出控制无人旋翼机飞行所需要的空速等数值,同时采用线性插值等算法来提高计算性能.该系统体积小,功耗低,抗干扰能力强等优点,能够满足小型无人旋翼机的需求,为小型无人旋翼机数据采集系统在实际中的应用做了一定的理论工作.The collection of atmospheric data plays a key role in the control of small unmanned rotorcraft flight. An atmospheric data acquisition system for the acquisition device of a small unmanned rotorcraft was designed by a digital MEMS sensor and TMS320F28335 chip based on the flight control needs of small unmanned rotorcraft. The space velocity required to control the flight of the unmanned rotorcraft is calculated in real time by collecting data with the sensor, and some algorithms such as linear interpolation are used to improve the calculation performance. The system can meet the needs of small unmanned rotorcraft because of its small size, low power consumption, and strong anti- interference ability, which has made some theoretical work for the practical application of small unmanned rotorcraft data acquisition system.
