This paper mainly aims at the characteristics of the hardware and software structure of the parallel computer on satellite, and has fulfilled researches of fault tolerant technique in three aspects of control theories and engineering : the first research of the system level fault - tolerant module is based on the system structure of the parallel computer on satellite, a kind of cold backup module and a kind of hot backup module for multiprocessor computer have been put forward. then the research of software fault tolerant technique which is based on the operate system named rtems has been carried, the mission level fault - tolerate arithmetic and the system level fault - tolerate mechanism and strategies based on the check point technique have been put forward, at the same time the self - repair technique of software which has used the technique of system re - inject has been studied. finally the technique of components level fault - tolerant based on fpga has been studied, a kind of two level fault - tolerant project which aims at the fault - tolerant module of the parallel computer on satellite has been put forward, and the augmentative of circuit that project design realization need is little, this project can avoid any breakdown of any part logic circuit of the fpga
本課題主要針對星載并行計算機體系結構及軟體結構的特點，從如下三個方面進行了容錯控制理論研究和實踐工作:首先進行了基於星載多cpu并行計算機體系結構的系統級容錯模型研究，提出了一種多cpu冷備份容錯模型和一種多cpu熱備份容錯模型;然後進行了基於rtems操作系統的軟體容錯技術研究，提出了任務級容錯調度演算法以及基於檢查點技術的系統級容錯恢復機制和策略，同時研究了利用系統重注入進行軟體在線自修復的容錯技術;最後研究了基於fpga的部件級容錯技術，提出了對容錯模塊這一星載并行計算機關鍵部件的兩級容錯方案，實現該方案所需增加的電路少，可避免板級晶元以及fpga晶元內部任何邏輯發生單點故障。 -
Based on static logic or static failure mechanism, the traditional fault tree analysis is a effective method to analyze system reliability. but it can not be used to analyze the reliability of systems with dynamic randomicity and dependency, such as fault tolerant system, repairable system with redundance ( cold spare or hot spare ), sequence dependency system and system with spare pool
傳統故障樹分析方法是基於靜態邏輯和靜態故障機理提出的一種有效的系統可靠性分析方法，不適用於對具有動態隨機性故障和相關性的系統，如容錯系統、冗餘（或冷、熱備件）可修系統、公用資源庫系統，具有順序相關性的系統的可靠性分析。 -
However, distributed fault - tolerant applications are hard to be developed, since the programmers must handle not only the complex business logic but also the confused fault tolerance logic. the latter one is often tedious and error - prone
但是直接開發分散式容錯應用是非常困難的，這是因為開發者不僅要處理復雜的應用邏輯，還要面對紛繁的容錯邏輯，處理不好會弄巧成拙，容錯成了「容易出錯」 。 -
After studying more deeply the fault tolerant algorithm and load balancing technology in redundant services, active load balancing is introduced into the redundant service system, and a novel fault - tolerant algorithm is built in this paper. under the conditions of guaranteeing the availability of redundant service system, the performance is effectively improved. the logic object model is based on corba and the prototype is implemented, additionally, system test results show the feasibility of the algorithm
本文在較深入地研究了冗餘服務中的容錯演算法、負載平衡的基礎上，通過在冗餘服務中引入主動負載平衡機制，提出了一種行之有效的冗餘服務容錯演算法；該演算法一方面能夠滿足客戶請求對可用性的要求，另一方面有效地提高了系統的性能；基於corba分佈計算通信平臺，本文還構建了該演算法的對象模型，並在此基礎上實現了一個原型系統，通過實例測試驗證了該演算法的可行性。
