摘要
小型无人机不论在军事还是民用方面都得到了广泛的应用,其导航、姿态、采集数据信息都需要串口与机载单片机进行通信,并且需要将传感器数据传送至地面控制站进行分析。设计实现由GM8125芯片进行单片机串口的扩展,通过传感器HMR3300和ITRAX02对无人机的姿态、导航数据进行采集,并通过GSMMODEMMC35将数据传送至地面控制站。
UAV (Unmanned Aerial Vehicle) has been applied both in military and people life. The data about navigation, pose and gathering is sent to MCU (Machine Control Unit) through UART, and MCU send it to GCS (Ground Control System) to analyze. This design carried out expanding UART by using GM8123, gathering the data by using HMR3300 and iTRAX02, and sending the data to GCS through MC35.
