摘要
针对航天应用领域某有效载荷设备的CCD信号采集需要,提出一种基于USB2.0的CCD信号采集方案,其中包括硬件接口设计和软件设计。采用FPGA加EZ-USB的系统架构完成硬件接口设计,USB接口芯片工作于从模式,信号传输采用批量传输模式,利用VC++6.0平台设计出信号采集软件。经ISE和Modelsim仿真以及EZ-USB硬件平台检验,系统实现了CCD信号采集,且运行稳定。
For the need of Charge Coupled Device(CCD) signal acquisition of some payload in spaceflight, a CCD signal acquisition scheme based on USB 2.0 is presented, including the hardware interface design and software design. The hardware architecture is implemented with FPGA and EZ-USB, the USB interface IC is in slave mode and the signal transmission mode is batch transmission. The signal acquisition application is designed on the platform of VC++6.0. The system realizes CCD signal acquisition and runs steady, which is proved with the emulator ISE and Modelsim, and the hardware platform based on EZ-USB
