摘　　要：光电保护装置(又称安全光幕)主要应用于电子电器制造业、地铁屏蔽门及自动化生产线等领域,能在人或物处于危险状态前使设备回复到安全状态从而提供保护。有效孔径角是光电保护装置检测认证中较易不合格的检测项目。本文以使用有源光电保护器件的安全光幕为例,解析其有效孔径角的测试原理及注意事项,以期为相关生产企业提供建议和参考。Photoelectric protective equipment(also known as safety light curtains)are mainly used in the fields of electronic and electrical manufacturing,subway shield doors,and automated production lines.They can restore working equipment or devices to a safe state before people or things are in a dangerous state to protect people or things.This article takes a safety light curtain using active optoelectronic protective devices as an example,and analyzes the testing principles and precautions for the testing items such as effective aperture angle that are prone to failure in optical performance testing and certification,and provides suggestions and references for related production enterprises.
