基于红外传感器的旋转式无人机保护装置

A Rotary Protection System for Drones Based on IR Sensor

旋翼安全是无人机飞行的关键问题,为防止旋翼桨叶伤人,本项目提出一种创新型的无人机旋翼保护装置。该装置采用了旋转式保护框结构,配合红外光学传感器实时地对周围环境进行侦测并在接触到危险时发出信号,通过单片机即时地做出保护反应。实验表明,装置能够全方位、全覆盖、即时地对旋翼进行防护,并且起到十分显著的保护效果且同时对无人机气动性能影响较小。该无人机旋翼保护装置同时还有结构和原理较为简单、成本及重量较低等优点,为无人机旋翼保护的方案设计提供一定的指导依据。

Rotor safety is one of the key problems to drones.Our project proposes an innovative drones rotor protection device in order to prevent the rotor blade cuts.The device uses a frame structure working with IR optical sensor to constantly detect surrounding environment,and then sends a signal to trigger a single-chip microcomputer to make protective response immediately when contacts with danger.Experiments show that the device can protect the rotor in an all-round,full-coverage and real-time manner,and it has a very significant protection effect and has little influence on the aerodynamic performance of drone.At the same time,the rotor protection device has the advantages of simple structure and principle,low cost and weight,which provides some guidance for the design of rotor protection scheme.
