舰船消防联动控制系统可靠性关键技术

Key technologies on reliability of naval ships automatic control system for fire protection

以舰船消防联动控制系统为研究对象,探讨提高系统可靠性的技术手段。采用故障模式影响分析(FMEA)定位消防联动控制系统薄弱环节,并针对薄弱环节采用可靠性、维修性、测试性、安全性、保障性设计方法提高系统整体可靠性,对设计方法中涉及的关键技术进行深入研究。通过分析研究形成提高消防联动控制系统可靠性相关的控制器通用化模块化设计技术、控制线路故障诊断技术、气体释放安全防护技术、消防联动控制辅助决策技术4项关键技术。在满足消防联动控制系统基本控制功能要求的基础上,开展可靠性关键技术研究,达到提升消防联动控制可靠性的目的,起到保障舰船火灾安全性,提高舰船生命力的作用。

Taking the naval ship automatic control system for fire protection as the research object,this paper discusses the technical means to improve the reliability of the system.Fault mode Effect analysis(FMEA)is used to locate the weak links of fire linkage control system.Aiming at the weak links,reliability,maintainability,testability,safety and supportability design methods are adopted to improve the system reliability,and the key technologies involved in the design method are deeply studied.Through the analysis and research,five key technologies are formed to control system,which are redundancy design technology of fire linkage control,universal modular design technology of controller,diagnosis technology of control circuit fault,safety protection technology of gas false release,and intelligent decision-making technology of fire linkage control.On the basis of meeting the basic control function requirements the fire linkage control system,the research on the key technology of reliability is carried out to achieve the purpose of improving the reliability of the fire linkage control system,so as to ensure the fire safety of the naval ship and improve the vitality of the naval ship.
