摘　　要：由于山洪灾害突发性强、危害性大、极难防御等问题,因此高可靠的山洪预警系统极为重要。目前国内普遍采用RTU对山洪进行预警。通过建立Markov模型分析单机系统和双机热备系统的状态转换过程,并且通过Matlab进行仿真分析,得出双机热备系统较单机可测系统可以明显提高RTU的可靠性。Flood disasters happen suddenly and may cause great damage, which is extremely difficult to defense, so a highly reliable flash flood warning system is very important. Currently RTU is widely used to warn flash floods. By establishing Markov model to analysis the conversion process of stand-alone system and dual hot standby system. We can conclude that dual hot system improves the reliability of the RTU better than han stand-alone measurement system through Matlab simulating and analyzing.
