    摘 要:針對供電綜合保護器對實時性的要求,結合μC/OS- Ⅲ實時操作系統(tǒng)對保護器中斷任務進行中斷管理設計。通過對μC/OS- Ⅲ系統(tǒng)中斷管理機制分析,將中斷任務分成內(nèi)核對象參與和無內(nèi)核對象參與,并對兩種中斷任務進行不同處理。為減少中斷延遲時間,提高保護器系統(tǒng)對異常事件的響應速度,將數(shù)據(jù)采集、數(shù)據(jù)接收、數(shù)據(jù)存儲等內(nèi)核對象參與的中斷任務選擇延遲發(fā)布模式。仿真實驗結果表明,中斷關閉時間最高為3.35 ms,提高了系統(tǒng)對中斷任務的快速響應和處理,保證了保護器的實時性和穩(wěn)定性。

    Abstract: Aiming at the real-time requirement of power supply comprehensive protection, combined with μC/OS-III real-time operating system, the interrupt management devise of the protector interrupt task is carried out. In this paper through the analysis of μC/OS-III system interrupt management mechanism, to divide the interrupt tasks into kernel object participation and non kernel object participation, and handle the two kinds of interrupt tasks differently. In order to reduce the interrupt delay time and improve the response speed of the protector system to the abnormal events, the delayed release mode is selected for the interrupt tasks involving data collection, data receiving, data storage and other kernel objects.The simulation experiment results show that the maximum interrupt closing time is 3.35 ms, which improves the system's rapid response and processing of interrupt tasks, and ensures the real-time and stability of the protector.
    Key words: integrated power supply protection; μC/OS-III real-time operating system; interrupt management; delayed release mode; real-time
