摘　　要：提出了在Windows XP下利用计算机并口通信读取光电开关信号的方法,给出了接口设计电路,并通过第三方软件利用Visual C++实现了对计算机并口的控制.通过在图像采集系统装置中的应用,表明该设计方法简单、使用可靠性好,而且还节约成本.This paper presents a method of reading the signals of the proximity switch through the parallel communication of the computer under the environment of Windows XP, gives the design of the interface circuit, and then by using Visual C ＋ ＋ develops the program through the third software. This method has been applied in the implement of image acquisition system, and it shows that the design of the method is easy, highly stable and of low-cost.
