移動裝備對遠程監控要求越來越多，監控系統具有的多任務特性越來越明顯。多任
務與系統運行穩定性之間存在一定矛盾，通過對移動裝備遠程監控系統的多任務分析，確立了基于任務優先級的調度機制。該文采用ARM 處理器和實時操作系統μC/OS-Ⅱ進行了對移動裝備的多任務遠程監控系統的設計和開發。為了避免系統因任務進程之間出現死鎖或其它原因而無法運行，采用硬件看門狗對系統進行復位處理。

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.
