摘　　要：在对特种体制雷达任务可靠性要求高的背景研究下,提出固态发射机监控系统的双热备份解决方案。发射机系统内部关键设备组成均采用冗余备份,设备之间采用控制局域网总线组网连接。监控系统的分机采用双热备份设计,主控制通道设备故障时,系统会自动切换到从控制通道继续工作,同时也易实现故障设备的在线维修。监控软件运行在具有多任务和实时性特征的嵌入式操作系统Vx Works平台上。文中对监控系统的实现方式和关键模块的组成原理作了详细描叙,并就如何提升发射机监控设计水平提出了一些见解。In the complex solid state transmitter system, the dual hot redundancy monitoring system design scheme is a good selec- tion. The system devices can be connected between the monitoring unit and the other units through CAN bus. When there is a fault in the working channels, the other channel can be switched to work automatically. So there is the features of on-line repairing. The computer installs the VxWorks operating system, which has characters of multitask and real-time. This paper introduces the realiza- tion way of monitoring system and composition principle of the core part. A few views are put forward to improve the transmitter mo- nitoring level.
