摘要 文章介绍了一种利用自检测和互监测方法保证故障监测覆盖率和虚警率,适用于双机热备冗余系统的故障监测技术,主要论述了系统的总体结构,讨论了实现系统主从机状态高速自动切换的关键技术,并重点阐述了在PXI热备冗余测控系统中采用的各种故障监测手段,最终实现了在非实时操作系统下热备冗余系统主从机状态的高速自动切换,提高了测试设备自身的可靠性,保证了测试数据的正确性,有效解决了多种场合下地面测控系统要求长时间不间断可靠工作的难题。 The fault detection technology of hot spare redundancy system is introduced in detail. This method can improve fault detection coverage rate and reduce false alarm rate using self monitoring and mutual monitoring. The frame of hot spare redundancy system based on PXI is introduced. And the key technique which can realize automatic switch between master and slave is discussed. By using various fault detection techniques in hot spare redundancy system based on PXI, the high--speed switching between master and slave can be achieved in a non--real--time operating system. It can raise the reliability of the test equipments and the accuracy of test data of the system. This is a very effective technique for ground--based monitoring system requiring long and reliable operation.
