【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。
[Abstract]:Under the background research of high reliability requirement for special radar task, a dual hot backup solution for the monitoring system of solid state transmitter is proposed. The key equipment in the transmitter system is composed of redundant backup. The control LAN bus is used to connect the equipment. The extension of the monitoring system is designed by double hot backup. When the main control channel equipment fails, the system will automatically switch to continue working from the control channel. At the same time, it is easy to realize the on-line maintenance of fault equipment. The monitoring software runs on the embedded operating system VX, which has multi-task and real-time characteristics. On the Works platform, this paper describes the realization of the monitoring system and the principle of the key modules in detail. Some opinions on how to improve the design level of transmitter monitoring are put forward.

【正文快照】： 0引言雷达发射机一般采用可变脉冲工作比方式工作,同时具有功率密度大、高压大电流和能量热耗高等特点,这就导致系统内的空间磁场分布具有很多不确定因素。显而易见,发射机符合干扰源的所有特性,因此,发射机往往也是雷达中可靠性最低的分系统,是制约雷达系统整体可靠性的关键
