民用飞机应急撤离信号系统测试台设计

Design of test bench for emergency evacuation signal system of civil aircraft

关于机上应急撤离相关配套设施的研究,长期以来都是民用飞机安全方面研究的重要领域之一,由于民用飞机的机上人员较多且较为分散,当飞机在空中飞行时出现紧急情况,成功迫降到地面后,需要将机上人员安全快速有序地撤离到机外指定地点。机上应急撤离成功的关键因素之一就是将应急撤离指令快速地通知到机上的每一个人(包括飞行员、乘务员以及乘客),飞机上的应急撤离信号系统就起到了这个作用,它建立了飞行员和乘务员之间快速简洁的联络通道,通过按钮、灯光及音响提示完成了应急撤离相关的信息沟通,有效提升了机上应急撤离的效率。为了保证应急撤离信号系统的装机质量,提升研制的效率,设计了一个应急撤离信号系统测试台,可用于应急撤离信号系统在地面进行全面完整的功能测试。

The research on emergency evacuation related supporting facilities has long been an important field of research in the field of civil aircraft safety.Due to the large and scattered number of personnel on board,when an aircraft encounters an emergency situation in the air and makes a forced landing on the ground,it is necessary to safely,quickly and orderly evacuate the personnel on board to the designated location outside the aircraft.One of the key factors for successful emergency evacuation is to quickly notify everyone on board of the emergency evacuation instructions.The emergency evacuation signal system establishes a fast and concise communication channel between pilots and crew members,and completes information communication through buttons,lights,and audio prompts,effectively improving the efficiency of emergency evacuation.In order to ensure the installation quality of the emergency evacuation signal system and improve the efficiency of development,an emergency evacuation signal system test bench has been designed,which can be used for comprehensive and complete functional testing of the emergency evacuation signal system on the ground.
