用于小型无人机的超声波低空测高系统实验研究

Experiment Research of Ultrasonic Low-altitude Measurement System for Using SUVA

根据声波在空气中传播反射的原理,设计了一种基于超声波模块600和单片机C8051F121组成的小型无人机测高系统。主要针对当无人机起飞、降落时,提高高度测量的精度,详细介绍了超声波模块600的工作原理、软件设计及对实验数据的分析并得出结论。

According to the principle of ultrasonic transmission in the air.In the paper,a system of altimetric measurement of SUVA was made up of a ultrasonic module 600 and a MCU C8051F121.Targeted for taking off and landing UAV,Improve the accuracy of altitude measurement,described the working principle of ultrasonic module 600,software design in detail and analyzed the data of experimental then the conclusion was drawn.
