Realization of UAT Airborne Message Encoding Based on vxWorks

首先,分析UAT机载报文协议格式和内容,研究UAT(Universal Access Transceiver)机载报文的编码方式,根据UAT机载长短报文类型,对机载的矢量状态报文、模式状态报文、辅助状态矢量报文和目标状态报文进行了分析,了解UAT机载报文数据源的外部接口和获取方法;其次,在vxWorks操作系统下,硬件采用PC104,提出了UAT机载报文的编码构架以及实现方式,并给出了vxWorks操作系统下的软件实现流程,为UAT机载报文编码的实现和UAT机载设备的开发提供了理论依据和参考;最后,对机载编码硬件的实时性及编码的正确性进行了验证,并给出了案例分析。

First of all, the format and content of UAT airborne protocol messages are analyzed. According to the UAT long and short airborne message type, the state vector message, mode state message, auxiliary state vector message and target state message are analyzed, and the external interface and access method of the UAT airborne data message source is understood in this paper. Under the vxWorks operating system, by adopting the hardware of PC104, the coding framework and implementation of the UAT airborne message are proposed and the software realization process is given to provide a theoretical basis and reference for UAT airborne message coding realization and UAT airborne equipment development. Finally, rightness of the real-time encoding and encoding of airborne hardware is validated, and case studies are given.
