摘要
空气采样早期烟雾探测系统也称为吸气式烟雾探测器,是一种基于光学空气监控技术和微处理器控制技术的烟雾探测装置。介绍了其工作原理及其特点:从等待烟雾的被动方式变为主动对空气进行采样探测。对传统火灾探测器和空气采样早期烟雾探测器在地铁环境中的应用特点进行了对比分析。提出在地铁特定区域内应采用空气采样早期烟雾探测器进行探测保护。
The working principle and features of air sample early smoke detection system is introduced, which is based on the monitoring of optical air and the micro- processing control technology. Compared with the traditional fire a- larm detectors used in metro environment, this system fea- tures active detection of air sample instead of passive alarm of smoke, and should be widely adopted in metro for early smoke detection.
