| Because the atrium fire experiment is always destructive, it is very important that the system must be well designed and properly organized, then the experiment data could be obtained accurately.This paper establishes a platform of computer monitoring system for atrium fire experiment , discusses the testing methods of smoke flow , and analyses the design of hardware circuit,the workout of software and its parameters and functions of the computer acquistion system for atrium fire experiment in detail. The acquistion system is mainly used to measure the most important parameters:the heat release rate and the temperature.Furthermore, The monitoring system is applied to a series of experiments in atrium models and we get a great deal of experiment data. According to the collected data, this paper analyses the characteristic of smoke flow and temperature distribution in atrium models and discusses the setting conditions, setting place and setting mode of the fire detectors . This will be consultative for fireproof design and will be useful for real atrium. |
