仪表着陆系统是为飞机提供精密进近的陆基导航系统,该系统必须能够精确,可靠的提供导航信息,确保飞机安全着陆。然而,由于乌鲁木齐是单跑道运行,飞机架次繁多,航线复杂,飞行安全压力大,特别是进入低能见度运行后。维护人员在平时维护中因为无法利用现有设备进行实际操作,仅仅从理论方面进行分析,对于维护人员,特别是新员工的培训造成很大的困扰,通过对仪表着陆系统的建模及仿真,可以改善以上存在的问题。论文主要研究仪表着陆系统中下滑信标的建模及仿真,首先阐述下滑信标发射机及天线的原理并仿真实现,其次探讨分析下滑信标接收机的工作原理并仿真实现,仿真实验结果表明本文仿真的下滑信标能够正确给出飞机偏离航道的指示,引导飞机进近着陆。从而让导航人员充分了解我们的设备的作用以及如何工作,在维护工作中更能理解其中的工作原理,提高每一位职工对所做工作的自豪感。
The instrument landing system is a land-based navigation system that provides a precision approach to an aircraft. The system must provide navigational information accurately and reliably to ensure a safe landing of the aircraft. However, since Urumqi is a single-track runner, it has a large number of aircraft racks and complicated routes, so the flight safety pressure is high, especially after entering the low-visibility operation. Maintenance personnel in the usual maintenance because they can not use the existing equipment for the actual operation, only from the theoretical analysis, maintenance personnel, especially new staff training caused great trouble, through the instrument landing system modeling and simulation, Can improve the above problems. This dissertation mainly studies the modeling and simulation of gliding beacons in instrument landing system. Firstly, the principle and simulation of gliding beacon transmitters and antennas are expounded. Secondly, the working principle of gliding beacon receivers is analyzed and simulated. The simulation results show that The simulated decline beacon can correctly give an indication of the departure of the aircraft from the waterway and guide the aircraft to approach and land. So that navigators fully understand the role of our equipment and how to work in the maintenance of a better understanding of the working principle of which every employee to enhance the work of pride.
