感烟探测器动作时间预测数学模型的应用

Application of mathematic model for predicting smoke detector activation time

针对目前国内缺乏一个科学合理的火灾感烟探测器动作响应时间预测方法的问题,介绍了两种预测火灾感烟探测器动作时间的数学建模方法和几个常用的计算探测器报警时间的数学模型,提出了模型中参数的设置与测试方法。通过一个计算实例介绍了该数学模型的使用,并简要介绍了该数学模型在场模型和区域模型中的应用,可为性能化防火设计与评估以及报警设备安装设计提供工具。

To resolve the problem of absence of tools for predic- ting the smoke detector activation time, two modeling approa- ches of predicting smoke detector activation time and some corn mon models were introduced, and the setup and acquisition method of parameters in the model were proposed. The application of those models were demonstrated through one example, and the combination of the smoke detector activation model and the zone fire model or field fire model were mentioned. Those methods can provide tools for fire performance based design or evaluation and smoke detector installation.
