        摘 要:冗余測控中的虛擬測控單元大部分時間是處于后備休眠狀態(tài),硬件利用率很低。介紹了一種虛擬測控單元自適應加載技術(shù),可通過實時監(jiān)測實體測控的運行狀態(tài)自動規(guī)劃虛擬測控單元的 CPU 資源部署,并通過任務的卸載、新配置載入、重啟相關(guān)任務的方式實現(xiàn)冗余測控裝置中各虛擬測控單元功能的動態(tài)釋放和重載。給出了裝置硬件設(shè)計及軟件架構(gòu),并對動態(tài)加載原則進行了闡述,通過該技術(shù)可以高效地復用硬件資源,大幅降低冗余測控裝置的制造成本。

        Abstract: The virtual measure-control unit of redundancy measure-control device, most of the time, is in the back-up and dormant state,and the rate of hardware utilization is low. This paper introduces an adaptive loading technology of virtual measure-control unit. It is a technology that is able to automatically arrange the CPU resource deployment of the virtual measure-control unit through the real-time monitoring of the physical measure-control device, and it can achieve the function of dynamic release and reloading of the virtual measure-control units within the redundancy measure-control device by unloading tasks, loading new configurations, and restarting related tasks. The hardware design and software architecture of this technology is presented, and the principles of dynamic loading is described. When adopting this technology, hardware resources can be reused efficiently, and the manufacturing cost of redundancy measure-control device can be slashed.
        Key words: redundancy measure-control device; virtual measure-control unit; physical measure-control device; function backup; adaptive loading
