基于Android平台的1090ES数据链数据采集系统

随着空中交通管理技术的发展,1090MHz扩展电文(1090ES)数据链已经成为承载地空通信、空空通信的重要数据链,在民用航空及通用航空领域得到了广泛应用。传统的二次雷达或ADS-B地面站设备大而沉重,为了构建便携、低成本的1090ES数据链数据采集系统,提出了一种基于Android智能终端和广播数据采集板卡的解决方案,利用1090MHz天线接收广播信号,由单片机(PIC18F2550)实现模数信号转换,通过USB-OTG接口发送至Android智能终端；开发了数据采集APP,实现数据的融合解译、数据采集以及航空器的飞行监视。经测试验证,系统能够有效采集1090ES数据链公开协议航空数据,覆盖范围超过150公里,即插即用,应用前景广泛。

Data Acquisition System for 1090ES Data Link Based on Android Platform[JZ)][HS)]

With the development of air traffic management technology, 1090MHz extended squitter (1090ES) data link which realize air-to- ground and air-to-air communication, has been widely used in the field of civil aviation and general aviation. Traditional radar or ADS-B ground station equipment is large and heavy, with the purpose of developing portable and low cost data acquisition system for 1090ES, proposed a solution based on android platform and radio module, using 1090MHz antenna to receive radio signals, with single chip microcomputer (PIC18F2550) to achieve digital signal conversion, in addition to communicate with android platform through the USB-OTG interface. A data acquisition APP was developed to realize data decoding, data persistence, and flight surveillance. After the testing and verification, the system can effectively collect the 1090ES aviation data, covering the range of over 150 kilometers, plug and play, and has a bright application prospect.
