摘要
安全飞行是无人机飞行的首要前提,控制信号的稳定传输与操控人员的安全操作扮演了至关重要的角色。文章设计了一种基于远距离无线电的无人机通信测距双系统控制平台,以远距离低功耗的LoRa调制为核心进行通信,同时向用户提供实时的距离信息。辅以自适应多制式选择,最大化系统的数据传输速率,并且采用跳频提高系统在嘈杂频段的抗干扰性能。
Safe flight is the first prerequisite of UVA flight,while the stable transmission of control signals and safe operation of operators play a vital role.In this paper,an UVA control platform based on long range(LoRa)technology with communication and ranging dual system is designed.The remote and low-power LoRa modulation is the core of communication,and real-time distance information is provided to users.With adaptive multi-mode selection,the data transmission rate of the system is maximized,and the anti-interference performance of the system in the noisy frequency band is improved by frequency hopping.
