摘　　要：随着农业技术的迅速发展,农用设备在现实生活中和农业生产中被广泛应用。然而,农用加工机械也存在着很多安全问题。在阐述了农用加工机械的危害的基础上,介绍了安全光幕即光电式安全装置。根据农用机械设备的安全现状,提出了基于光幕保护人身安全系统的设计。设计的控制程序根据农用机械保护系统所处的不同阶段对控制器的任务实行转换连锁的方法,保证了系统的高速、高精度安全。With the rapid development of agro-technology, agricultural machinery has been widely applied in practical life and agricultural production, but it still faces lots of safety issues. Based on expounding the harms of agricultural machinery, the safety light curtain, that is, the photoelectric safety device, is introduced, according to the safety status of agricultural machinery, the human safety protection system is designed based on light curtain. The tasks of controller are converted according to different stages of agricultural machinery protection system, which guarantees the high-speed and precise safety of the system.
