摘　　要：介绍了一种光电检测的食堂售饭系统的设计与试验，介绍了系统的工作原理和系统结构组成，以及系统软、硬件设计。其中应用了模拟电路，数字电路及光电转换电路，最后由PC机来实现操作控制。该实验可作为仪器专业学生对光电技术实验课的一项实验课题。This paper introduces design and experiment of a cafeteria selling system based on photo- electronic detection, including the system working principle, compose of the system, the design of the hardware and software of the system. In this system, anolog circuit, digital circuit and photo-electricity transform circuit are used. The function operation was finally realized by PC. It can be used in an experimental course of photo- electricity technology for the students whose major is in instrument designing.
