摘　　要：随着测控网络系统的广泛应用,用于完成对设备的遥控、遥测、跟踪定位及传输传感器信息的测控系统,其稳定性在未来的信息化战争中扮演越来越重要的角色。因此设计和开发双机备份技术适应高稳定的测控网络系统,就显得尤为重要。双机备份是一种软硬件结合的较高的容错应用方案。双机备份方案中,根据性质和需要可以由3种不同的工作模式:即双机热备模式、双机互备模式和双机双工模式。双机备份模式的引入,极大的提高了测控系统的可靠性与安全性。With the wide application of Tracking, Telemetry and Command （TT＆C） network system, the TT＆C system, which is used to accomplish the telecontrol, telemetry, tracking and positioning of equipment and the transmission of sensor information, plays more and more important role in the future information warfare. Therefore, it is important to design and develop the dual-machine backup technique to meet the highly stable TT＆C network system. The dual-machine backup is the highly combined fault-tolerant application scheme of software and hardware. In the dual-machine backup scheme, there are three different operating mode based on characteristics and requirements, such as dual hot-backup, dual active and dual duplex. The introduction of dual-machine backup mode greatly increases the reliability and safety of TT＆C system.
