摘　　要：本文遵循USB1.1总线协议,在航空相机主控系统中实现了嵌入式USB-HOST系统,通过对U盘的插入检测、枚举配置,并实现大容量存储协议及创建FAT文件系统,成功将航空相机内部重要参数实时存储于U盘中。USB-HOST数据监测模块工作稳定可靠,为航空相机的调试及联试工作提供了方便。Complying with Universal Serial Bus Specification Revision 1.1,USB-HOST system is realized in the main control system of aerial camera.By means of the insert detection and enumeration of U disk,as well as the realization of mass storage class specification and FAT16 file system,the important parameters inside the aerial camera are stored in U disk real-timely.The module of USB-HOST works stably and reliably,which is convenient for the debugging and combing test of aerial camera.
