摘要:

针对民用无人机体积小、重量轻、结构简单、可靠性高等要求,给出了一种以STM32F103RE微控制器为核心的小型无人机的硬件系统设计方案,并详细介绍了系统整体方案设计以及主要的功能模块；通过详细的结构框图描述了如何有效的将各功能模块组成一个稳定的系统；在小型固定翼无人机上的飞行测试验证了该设计方案的可行性和可靠性；该系统实现体积小,可以封装到一个小盒子里面,所有接口单独引出,可以挂载到不同的载体上；该系统具有精炼、低成本、可靠性高的特点,适合批量生产使用。

Abstract:

The main requirements for civilian UAV are small size, light weight, simple structure and high reliability. In this paper, we proposed a flight control hardware for civilian UAV based on STM32F103RE microcontroller. At first, the design of the overall scheme for the flight control system is introduced. Then, the main modules of this system are described in more details. A detailed block diagram is presented to show that all the modules are combined a into stable system. The results of flight experiment on miniature fixed wing show that this flight control system is feasible and reliable. The realization of the proposed system is so small that it can be packaged into a small box, which educed all the interfaces that are simple to mount on different carriers. Furthermore, this system has a refining, low cost, high reliability characteristics, so it is suited for mass production and use.
