摘　　要：卫星光通信终端系统对实时性和可靠性均有要求,针对不同备份方式,在不同故障覆盖率下,利用马尔科夫链理论对该系统的可靠性进行分析.仿真结果表明,冷备份方式的系统可靠性比热备份方式的系统可靠性高,故障覆盖率为1时,采用冷、热备份相结合方式,能够同时满足系统的可靠性与实时性需求.Satellite optical communication terminal system must be real-time and reliable. For different backup and fault coverage, the paper analyzes the reliability of the system using Markov chain theory. The simulation results show that system reliability for the cold backup is higher than that for the hot backup. That can meet the requirements of reliable and real-time of the system when the fault coverage is 1.
