摘　　要：本文是在充分研究了智能故障诊断、容错控制以及可靠性理论的前提下,运用FPGA、Nios处理器、控制理论、人工智能等相关知识,提出了一个能在实际的网络系统中提高服务器运行可靠性的有效方法——温备份智能容错系统。该方法使用Nios软核处理器以及FPGA的优点,运用SOPC Builder工具设计了一个智能仲裁器的核心部件。该仲裁器能够智能地获取服务器的状态、同步服务器的内容以及控制服务器的开启和关闭。从而提高了系统的可靠性,延长了服务器的使用寿命。本文给出了该方法的实现模型及详细实现步骤。　Based on the study of Intelligent diagnose of fault,control of containing fault and theory of reliability,a new method is put forward in this paper applying knowledge of FPGA,Nios processor,theory of control,artificial intelligence and so on,which is a very effective method for improving reliability of server＇s running in actual system of network. This method uses advantages of Nios soft core processor and FPGA and designs a core component of intelligent arbitrator by SOPC Builder tool,which get status,synchronize content of servers and start and stop server of server intelligently. It improves reliability of system as well as prolongs life of server. This paper shows the application model of this method and the detailed steps.
