OSID火灾探测新型技术及 在城市轨道交通中的应用

分析城市轨道交通行业的高大开放空间火灾探测的现状,指出传统火灾探测器的不足,详细阐述高大开放空间成像探测器(OSID)的工作原理和关键技术。OSID采用双波粒子检测、感光元件光学成像、预对准光学成像等多项先进技术,而且支持多发射器-单接收器。将OSID与线型光束感烟火灾探测器和吸气式感烟火灾探测器进行对比,指出OSID的主要优缺点。给出OSID在民用领域和城市轨道交通领域的典型应用,OSID可为城市轨道交通领域的火灾探测提供参考。

New Technology of Fire Detecting Using OSID and Its Application in Urban Rail Transit

This paper analyzes the status of open space fire detection in urban rail transit industry and points out the shortcomings of the traditional fire detectors.The working principle and key technology of open space imaging detector (OSID) is stated.OSID adopts the double wave particle detection,CMOS optical imaging,pre-alignment and other advanced technologies,and supports multi transmitter with a single receiver.OSID,optical beam smoke fire detector and aspirating smoke fire detector are compared,and the main advantages of OSID are presented.Finally,the typical applications of OSID in civil domain and urban rail transit area are presented.It is pointed out that and OSID would be a nice reference of fire detecting solution in the urban rail transit area.
