The accuracy of the impact performance for safety glass has a close relationship with impact high position. This paper introduces a high automatic control device which uses the photoelectric sensor based on AT89S52 SCM. The device use the single chip processor as the core processing, the integrated use of photoelectric sensor technology and stepping motor technology to realize the accurate control of drop height.% 安全玻璃霰弹袋冲击性能检测的准确性与冲击高度的定位有密切的关系。本文介绍了一套基于AT89S52单片机，采用对射式光电传感器设计的冲击高度自动控制装置。该装置以单片机为处理核心，综合运用光电传感技术和步进电机技术实现对冲击高度的精确控制
