【摘要】：随着经济快速发展,人们出行和货物的运输逐渐依靠飞机实现,快速增长的航班量就要求大量的软、硬条件跟随发展,作为飞行活动的重要因素,空中交通管制部门在人员和通讯设备也迎来的大发展,为方便地面管制人员与飞行器沟通所使用的地空通信台站逐渐增多,多个台站同一频率逐步实现了双重或多重覆盖,台址、频率的不断增加为地空通讯提供更多安全保障的同时,也为彼此干扰埋下了隐患,本文主要是研究如何让同频异址电台发挥其应有益处的同时,根据实际情况,选择一定的手段和方式来监测和控制相互干扰,为飞行器提供更安全有效的使用环境。本文通过分析空管地空通讯网络的结构,逐段找到产生干扰的原因,真对不同设备的特点,找到合适的解决方法,利用滤波器和电台自身的特点,改善无线设备的前端选择性,使用硬件和编程工具,对传输信号进行检测,实现干扰信号的切断和其他备份路由的切换,最终实现对干扰信号的检测和控制,利用VoIP等新技术的特点,在传输过程中避免干扰的产生。
[Abstract]:With the rapid development of economy, people gradually rely on aircraft to travel and cargo transportation. The rapid increase of flight volume requires a large number of soft and hard conditions to follow the development, as an important factor in flight activities. The air traffic control department has also ushered in a great development in personnel and communication equipment. In order to facilitate the communication between ground control personnel and aircraft, the number of ground-to-air communication stations has gradually increased, and multiple stations have gradually realized double or multiple covers at the same frequency. The increasing frequency and frequency of the station provide more security for ground-to-air communications, but at the same time, it also buries hidden dangers for each other's interference. This paper mainly studies how to make the same frequency and different address stations give full play to their due benefits, and according to the actual situation, In order to provide a more safe and effective operating environment for aircraft, a certain means and method is chosen to monitor and control mutual interference. By analyzing the structure of ATC ground-to-air communication network, the causes of interference are found step by step. To find appropriate solutions to the characteristics of different equipments, to improve the front-end selectivity of wireless devices by using the characteristics of filters and radio stations, and to use hardware and programming tools to detect the transmitted signals. The jamming signal can be cut off and other backup routes switched. Finally, the interference signal can be detected and controlled, and the interference can be avoided in the transmission process by using the characteristics of VoIP and other new technologies.
