摘要
雷达情报服务器是航管系统的关键设备之一,用于收集雷达信息并将其传输给航管主机。提出了一个雷达情报服务器的软硬件设计方案,硬件以串行通信控制器Z85230与ARM9微处理器AT91RM9200为基础,软件基于Linux操作系统。文中重点阐述了Z85230和AT91RM9200的硬件接口设计、基于Linux的多链路协议整合以及底层驱动实现这三个关键技术。
Radar information server is an important part of an Air Traffic Control(ATC) system.It collects radar information and transmits to ATC host.The paper presents a design of radar information server using serial communications controller Z85230 and ARM9 Microprocessor AT91RM9200.Software design is based on Linux.The paper elaborates on three aspects:hardware interface between Z85230 and AT91RM9200,multiple link protocol support,and access to Z85230 through Linux interfaces.
