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.
