Assumption of smoke detectors based on the conductivity of carbon black;

一种基于炭黑导电性能的感烟探测器的设想

The article uses FDS to study the effect of environment temperature and setting position on the alarm time of smoke detectors.

通过在水平方向上设置多组感烟型火灾探测器,对比分析了0℃、10℃3、0℃的环境温度下,不同位置感烟探测器报警时间的差异和规律性。

The experimental data of detection and sensing information were collected by a multi-information collecting system and compared with those from national standard fire tests,which presented the characteristics of cooking fumes interferential experiments and could be taken as the reference data for preventing smoke detectors from the interference of cooking fumes.

在标准燃烧室内,利用多信息数据采集系统,设计3种典型烹调油烟干扰实验,采集了多种探测传感信息的实验数据,并与国家标准试验火实验数据进行比较,得出了烹调油烟干扰实验的特征规律,为感烟火灾探测器避免烹调油烟干扰提供了参考数据。
