摘　　要：以S10201-04-01这一款TDI-CCD为设计对象,介绍了TDI-CCD的结构及其工作原理,采用FPGA作为主控制器,通过设计电压转换、驱动时钟电平转换、A/D采集、USB传输等硬件电路完成整套驱动电路的搭建,使用Verilog语言对S10201-04-01的驱动时序进行硬件描述并在Modelsim软件中对驱动时序进行仿真,最后在ISE14.7平台编译并下载到驱动板中,将一帧2048个像元接收的相对光强通过USB传输到上位机中显示(在实际光照强度不同的情况下,上位机中显示像元的相对强度也不同),完成了对S10201-04-01的驱动以及一帧数据的传输与显示。TakingS10201-04-01 TDI-CCD as the design object,the structure and working principle of TDI-CCD are introduced,using FPGA as the main control,through the design of voltage conversion,drive clock level conversion,A/D acquisition,USB transmission and other hardware circuit,complete the hardware system construction of the drive circuit.The hardware description of the driving sequence ofS10201-04-01 is carried out by using Verilog language,and the driving sequence is simulated in Modelsim software.Finally,it is compiled and downloaded to the driver board on ISE14.7 platform,and the relative light intensity received by 2048 pixels of a frame is transmitted to the upper computer through USB for display.Under the circumstance of different illumination intensity,the relative intensity of display pixel in upper computer is different.The drive ofS10201-04-01 and the transmission and display of one frame of data are completed.
