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。
Firstly, this paper analyzes the format and content of UAT air-borne message protocol, and studies the encoding method of UAT (Universal Access Transceiver) air-borne message. According to the type of UAT air-to-air message, the airborne vector state message, mode state message , Auxiliary state vector message and target state message are analyzed to understand the external interface and acquisition method of UAT airborne message data source. Secondly, under the vxWorks operating system, the hardware adopts PC104 and proposes the UAT airborne message Coding framework and implementation, and gives the vxWorks operating system software implementation process for the UAT airborne message encoding and UAT airborne equipment development provides a theoretical basis and reference; Finally, the airborne coding hardware Real-time and coding correctness is verified, and gives a case analysis.
