本文对遥控虹吸系统的运行可靠性进行了评估。虹吸系统由水位开关、通风口、舱底泵等组成。本研究应用基于ExtendSim软件的可靠性框图(RBD)模型对遥控虹吸系统的运行可靠性进行评估。基于径向基函数模型的蒙特卡罗仿真结果表明，通过增加水位开关、通风口等易损坏部件的冗余度，不可修复虹吸式系统在一年的生命周期内的运行可用度从0.683提高到0.855。采用现场维护策略时，该值可提高到0.999。在对多种场景和维护策略进行分析的基础上，提出了一种适用于信标系统的体系结构。
This paper presents the operational reliability assessment of a remotely controlled siphon system. The siphon system consists of water level switches, air vents, bilge pumps, etc. In this study, the reliability block diagram (RBD) model based on the ExtendSim software is applied to assess the operational reliability of a remotely-controlled siphon system. The Monte-Carlo simulation results from the RBD model demonstrate that the operational availability of the nonrepairable siphon system can be enhanced from 0.683 to 0.855 within a 1-year life cycle by increasing the redundancy for the vulnerable components, such as the water level switch and the air vent. The value can increase to 0.999 when adopting an on-site maintenance strategy. Based on the analysis of multiple scenarios and maintenance strategies, a suitable architecture of the siphon system is proposed herein.
