摘要
无人机相比较卫星和载人航空飞机遥感平台而言,具有成本低、灵活性高的特点。为了满足科学遥感实验、完成遥感作业任务、协调无人机电子吊舱中多组件工作、控制遥感影像传感器姿态,系统以AT89S52为主控芯片,扩展多路串口及USB接口以实现系统与外围设备的通信,同时设计了相机驱动模块及三自由度步进电机驱动模块。通过无人机航空遥感实验证明该系统能够满足遥感实验要求。
The remote sensing platform of UAV(Unmanned aerial vehicle) features lower cost and higher flexibility than those of satellite and manned aerial aircraft.In order to meet the requirements of remote sensing experiments,accomplish remote sensing task,cohere with the operation of multi-components in UAV electronic pod,and control the attitude of the remote sensing image sensors,AT89S52 is adopted as a main control chip in the control system.Multi-serial ports and USB interfaces are designed to realize the communication between the control system and the peripheral equipments,meanwhile the camera drive module and three degrees of freedom stepping motor drive module are designed.The results of UAV aerial experiments prove that the control system can meet the requirements of the remote sensing experiments.
