【摘要】 助航灯光系统是机场必要的设施,在夜间或在能见度不好的情况下引导飞行员,帮助飞机起飞或降落,保证了飞机的安全。随着管理的现代化,要求助航灯光系统能进行智能检测和控制。助航灯光检测系统能节约大量能源,及时找到故障点,确保整个助航灯光系统的完整运行,从而保证飞机的安全升降。 目前国内外对本课题的研究经检索未见相关的参考文献,仅见于产品说明书,而且这些产品(国外)都要求使用相应的调光设备,价格昂贵,对众多已投入运行的机场来讲是不现实的,大大限制了机场管理现代化的发展。 本论文深入系统的研究了目前存在(及可能采用)的方案,花费大量的时间对系统设计的难点进行试验,得到最直接、准确的数据,并对汕头机场、厦门机场的灯光系统进行分析和测量,最终得出系统设计需考虑及解决的问题。根据所分析的难点和方案,本论文提出了一种新的方案:基于红外线通信的通信网。新方案突破传统方案的诸多限制,彻底解决隔离变压器及不同类型调光器所引起的难题,满足各种机场的需要。新方案提出了新的红外光传送环路结构和访问控制方式,解决通信网中的关键问题:红外光的通讯距离,自然和人工光线对红外传感器的干扰,多个出入口信息在同一通讯环路上的信息冲突,实现对机场引航灯光系统各类故障的可靠定位及控制,建立一个可供实际应用的低成本系统。实验证明,基于红外通信的新方案能可靠的进行数据的传输和状态的检测,摆脱了调光器的限制,达到较为理想的要求。更多还原

【Abstract】 Airfield Navaid Lighting System is an essential part of an airfield. At night or bad visibility, it can help the pilot to take off and land the airplane and ensure the airplane safety. As the modernization of airfield management developing, it is required that Airfield Navaid Lighting System can provide intelligent detection and control. Airfield Navaid Lighting Detecting System is able to find out the faults and make sure the whole navaid lighting system running well. So it is good to save energy and ensure the safe take-off and landing of airplanes.At present there is little reference on the subject except several product specifications. All the products ask for the corresponding constant current lighting adjustor, which is too expensive for the current working airfields to apply. It is a great limit to develop the modernization of airfield management.In the thesis, some existent and adoptable projects are researched. Spend many time studying the system difficulties and get the first-hand and exact data. The problems, which must be considered and solved in design, were proposed, after studying and measuring the Xiamen Airfield and Shantou Airfield. Propose the new project that network of communication based on infrared ray. The new project breaks through the many restricts of conventional method, and thoroughly resolve some problems that are due to isolation transformer and different constant current lighting adjustor. The new infrared light transfer circulation circuit structure and access control method are proposed. Some key problems such as the communication distance of infrared light, interfering infrared sensor by reason of the natural and artificial ray and the information interference in identical communication circulation circuit because of several entrance-exit information are solved. Implement reliable localization and control of Airfield Navaid Lighting System troubles, and establish a low cost system that can be practical application.The new project based on infrared ray can reliably process the data transfers and state detection.更多还原
