摘　　要：介绍一种基于CPLD的多光谱数字遥感相机调焦控制系统的设计方法。使用VHDL硬件语言作为CPLD的输入方式。重点介绍了串行接收模块,控制模块的设计方法。经过仿真验证了该系统可以完成相机调焦的功能。该设计也可提高系统的可靠性和稳定性。A design and realization of a focusing control system of a multispectral digital camera based on CPLD was introduced. The CPLD was programmed by VHDL. The designs on serial receiver and control module were introduced emphatically. It is demonstrated by the emulation that the system can complete the function of focusing control. The design also improves the dependent and stability of the system.
