在vxWorks嵌入式实时操作系统下,硬件采用PC104,实现了网络和串口的主备份ADSB地面站之间进行信息交互,通过主、备份机器之间的心跳计数器完成主、备份机器之间的自动切换,使得ADS-B地面站给监视终端的数据保持连续,保证了管制员对目标的全天候实时监控,确保空中交通的安全。同时提供命令接口供用户强制实现主、备机器的切换,解决了空管设备的双机热备份之间的自动切换。
In vxWorks embedded real-time operating system, the hardware PC104, the network and serial port to achieve the main backup ADSB ground station to exchange information between the main and backup machines through the heartbeat counter between the main and backup machines automatically switch , So that the ADS-B ground station to monitor the data terminal to maintain a continuous, to ensure that controllers on the target real-time monitoring around the clock to ensure the safety of air traffic. At the same time provide a command interface for users to force the main switch, switch the machine to solve the ATC equipment automatically switch between the two hot backup.
