基于多种火灾报警技术融合检测的隧道火灾联动控制系统设计探讨

Discussion of Designing Tunnel Fire-fighting Automatic Control System Based on Fusion Detection of Various Fire Alarm Technologies

为提高隧道火灾报警系统可靠性和实现系统联动控制,根据火灾报警设计新规范对海底公路隧道火灾自动报警系统设计的新要求,在工程设计实践中构建冗余控制系统,标准化设备布设;通过研究火焰探测和感温探测两种技术的融合定位问题,采取对策降低了定位精度对联动控制的影响;梳理隧道交通工程机电设备联动控制的关键逻辑关系,形成一套高可靠且具备普遍意义的工程实施框架,为国内交通工程设计的发展和提升积累了建设经验。

In order to improve the reliability of tunnel fire alarm system and realize its automatic control,according to the new requirements of automatic fire alarm system design for subsea highway tunnel in the new fire alarm design specifications,a redundant control system is constructed and the equipment layout is standardized in engineering design practice. By studying the fusion positioning of the technologies of flame sensing and temperature sensing,the countermeasures are taken to reduce the influence of positioning accuracy on the automatic control. Meanwhile,the key logic relations of automatic control for tunnel traffic engineering electrical equipment is sorted out to form a highly reliable and universal framework for engineering implementation,which contributes to accumulate construction experience for the development and promotion of domestic traffic engineering design.
