【摘要】 针对现在航天遥感相机传输数据量大、传输通道多、传输速度快等特点,本文设计了一种以高速FPGA为控制核心,高速串行收发器为传输核心,LVDS为传输接口的高速图像传输系统。论述了传输系统的基本原理和设计重点,主要以CRC校验方法和眼图为测试方法,对高速传输系统的信号质量和完整性进行研究与测试。测试结果表明本系统工作可靠,无误码,满足高速航天遥感相机数据传输要求。更多还原

【Abstract】 To transmit remote sensing image data of multi-channel,high speed and huge amounts,an image transmission system is developed based on high speed LVDS serial interface in the paper.the thesis distance CCD system in a remote sensing camera.FPGA is the control center of the whole system.The serial transceiver is the core of the whole system.The paper discusses the design principle and design keys of the system.The signal quality and integrality are tested by CRC and eye diagram waveform.The test results indicate that the system works stable and no error code,which can meet the requirements of high speed Space Remote image Transmission.更多还原
