【摘要】：随着民航运输事业的迅速发展,日益繁忙的航路流量和航空吞吐量造成飞机密度增加,而由于雷达监测站的建立和布站受地形环境的因素影响较大,沙漠、洋区及偏远地区都会成为雷达的监视盲区。与此同时,近年来我国低空空域不断开放,通用航空发展迅速,但低空空域管制设施如低空通信、雷达设备严重不足,因此,传统监视手段已不能有效地进行空中交通管制,满足航空安全的需要。广播式自动相关监视(Automatic Dependent Surveillance-Broadcast,ADS-B)作为未来主要的民航监视手段,已被世界各国推广应用。而加快推广应用ADS-B是我国由民航大国向民航强国迈进,建设新一代航空运输系统的重要任务。本文设计了基于ADS-B多地面站的实时监视系统,以分散的远端地面站为ADS-B数据来源,旨在获取盲区的监视数据对其进行实时交通监视。研究内容主要包含以下几部分:首先实现单个地面站的监视数据的处理,主要有报文的接收采集、预处理、解析及原始报文和解析数据的保存;然后研究在广域网下数据的传输,实现将多个地面站采集处理后的数据实时传输到数据中心,并将数据进行汇总保存;针对ADS-B报文中漏点问题,结合ADS-B报文位置报和速度报不同时下发的特点,对变维卡尔曼滤波进行改进,提出位置/速度混合卡尔曼滤波算法,对多个地面站汇总后的ADS-B数据进行滤波处理,生成航迹信息;最后设计数据中心显示模块,实现多地面站的航迹的实时显示,及单架飞机的历史轨迹回放功能。
[Abstract]:With the rapid development of civil aviation industry, the increasingly busy route traffic and air throughput caused by aircraft density increased, due to the establishment and radar monitoring station station affected by terrain environment greatly, desert, ocean areas and remote areas will become blind area surveillance radar. At the same time, in recent years, China's low altitude airspace constantly open, general aviation has developed rapidly, but the low altitude airspace control facilities such as low-level communication, radar equipment seriously insufficient, therefore, the traditional monitoring methods cannot effectively carry out air traffic control, to meet the needs of aviation safety. ADS-B (Automatic Dependent Surveillance-Broadcast, ADS-B) as the main means of the future civil aviation surveillance, has been extended used all over the world. And accelerate the application of ADS-B is our country from large aviation industry to power forward, the construction of a new generation air transportation system An important task. This paper designs a real-time monitoring system of ADS-B ground station based on distributed remote ground station for the ADS-B data source, real-time traffic monitoring of the monitoring data to get blind. The research content mainly includes the following parts: first of all to achieve processing of monitoring data of a single ground station, the main message received collection, preprocessing, analysis and preservation of the original message and data analysis; and then study on data transmission in wide area network, to achieve multiple ground stations after the acquisition and processing of real-time data transmission to the data center and the data collection and preservation; aiming at the ADS-B packet, ADS-B packet with the position and speed of newspaper report issued by the characteristics at the same time, the dimension of Calman filter was improved and put forward the position / speed mixed Calman filtering algorithm to filter the multiple ground stations collect ADS-B data In the end, the data center display module is designed to realize the real-time display of the track of the multi ground station and the function of the historical track replay of the single aircraft.
