传感器在城市轨道交通火灾自动报警系统中的应用研究

Research of Sensors in Fire Alarm System of Urban Rail Transit

随着城市轨道交通的快速发展,火灾自动报警系统在城市轨道交通安全运行中的重要作用不容忽视。火灾探测器是火灾自动报警系统的重要组件,是报警系统的"感觉器官",不同场合或保护区域适合不同类型的火灾探测器。分析探测原理及应用特点,解决地铁站厅、站台、区间隧道、设备房等保护区域传感器的合理选用问题,同时为地铁火灾自动报警系统(FAS)维护人员及城轨专业相关课程的学习提供参考和帮助。

With the rapid development of urban rail transit in China,the important role of Fire Alarm System in urban rail traffic safety can not be ignored. Fire detector is an important component of FAS. It is also the ＂ sense organ＂ of alarm system,and it is suitable for different types of fire detectors in different occasions or protected areas.Many types of sensors can achieve fire detection,analyzing them from the principle and application of feature detection. They have reasonable selection of sensor from the subway station hall,platform and tunnel equipment,housing protection area,provide reference and help for FAS staff and study of Urban rail course.
