ABSTRACT:With the development of electrical, electronic and control measures of technology progress, especially in the PC as application of industrial control equipment, more and more practical application of motion control system. Application of optical focusing technique in life more and more frequently.

　　　This paper is titled as "the optical focusing system software design based on the movement control card", based on the PCI motion control card as the foundation, to build the hardware platform and draw the hardware circuit diagram, and the detailed design of the MFC motion control software. The hardware mainly includes the PC, motion control card, driver, stepper motor, this paper focuses on the design of motion control card.

　　　Software components use MFC design software, dynamic link library using Advantech company provides motion control card, expansion design. And the program designed to take full account of the system without power, restart the unexpected events such as effective preservation of important information. This paper provides the use of MFC programming the control software and provide the source code.
