基于DSP的小型农用无人机导航控制系统设计

为适应农业信息化要求,针对农业用小型无人机要求体积小、质量轻、稳定、可靠、低空低速飞行的特点,该文提出了一种小型无人机导航控制系统,其导航控制与数据采集采用单独DSP芯片进行处理,以降低导航控制系统的复杂度。系统以TMS320F2812芯片为核心,集成了GPS、红外传感器和电子罗盘,并扩展了DSP芯片异步串行通信接口,保证了数据通信的实时性、完整性和可靠性,实现了无人机的自主导航控制。飞行试验表明,该设计方案具有较高的可靠性。该研究可为农业用小型无人机的设计与应用提供参考。

Autonomous navigation control system of agricultural mini-unmaned aerial vehicles based on DSP

In order to enhance agricultural informatization, and according to the requirements of mini-unmaned aerial vehicles(UAV) for agriculture use with features of small size, light weight, stable, reliable, low speed and low altitude, a mini-UAV which using a respective DSP for navigation control and data collection was developed to reduce the complexity of navigation control system. The UAV uses TMS320F2812 as a core chip which integrates GPS, infrared sensor and electronic compass. The chip also expands the F2812 chip asynchronous communication interface. All of these designs ensure the real-time, integrity and reliability of data communication, and can achieve the independent autonomous navigation of UAV. The flying experiments of the UAV showed that the design had high reliability. The research can provide a reference for the design and application of agriculture-used UAV.
