摘　　要：为了满足高性能飞行器安全可靠的需求,容错计算机因其有效的故障处理机制得到了广泛应用。然而,基于传统架构的容错技术由于硬件资源的不合理配置会导致计算机重量和体积的成倍增加。综合化的容错计算机使用ARINC 659总线及相关软件进行故障检测、隔离,并将航电分系统和机电分系统综合管理和控制,从而有效解决了故障处理和硬件资源的优化问题,测试结果表明,计算机较好地完成了预期功能。In order to meet the requirements of high-performance aircraft′s safety and reliability,the fault-tolerant computer has been widely used because of effective fault handling mechanisms.However,the fault-tolerant technology which based on traditional architecture has doubled and redoubled the weight and volume of the computer due to the irrational configuration of hardware resources.The integrated fault-tolerant computer uses the ARINC 659 bus and related software to detect and isolate faults,then it comprehensively manages and controls the avionics sub-system and the electromechanical sub-system,finally,it effectively solves the optimization problem of fault handling and hardware resources.The test results show that the computer performs the expected function well.
