重大装备远程监控终端研究

移动装备对远程监控要求越来越多，监控系统具有的多任务特性越来越明显。多任
务与系统运行稳定性之间存在一定矛盾，通过对移动装备远程监控系统的多任务分析，确立了基于任务优先级的调度机制。该文采用ARM 处理器和实时操作系统μC/OS-Ⅱ进行了对移动装备的多任务远程监控系统的设计和开发。为了避免系统因任务进程之间出现死锁或其它原因而无法运行，采用硬件看门狗对系统进行复位处理。

Abstract: Motional equipment requires more and more in remote monitoring, the system’s
characteristic of multi-task becomes more obviously. There is some contradiction between
multi-task and the running stability of system. Through doing a task analysis for the remote
monitoring system, the schedule mechanism is established based on the priority of task. This paper designs a multi-task remote monitoring system of motional equipment based on ARM processor and μC/OS-Ⅱ. In order to avoid the system’s operation failing, the system would be reset via hardware watchdog.
