| Abstract | Green housing and "smart construction site" arc the hot spots of architectural research, but the relevant research is relatively simple. Meanwhile, fire is an important accident affecting the living experience of "green housing" and the construction progress of "smart site". Therefore, the fire early warning system during the construction of "smart site" and "green housing" is constructed, its effectiveness and applicability are explored, and the influence of combustible dust concentration and temperature on the system response is analyzed. It is found that: (1) the response times of the four confirmatory experiments of the fire early warning system are 0.0378 s, 0.0413 s, 0.0342 s and 0.0373 s respectively, indicating that the "smart site" fire early warning system is effective and can be used in the "smart site" construction site; (2) The increase of combustible dust concentration in buildings can improve the response speed and reduce the response time of "smart site" fire early warning system. When the combustible dust concentration in the building site is only 0.015 mg/m3, the response time of the early warning system is 0.034s, while when the combustible dust concentration in the building site is only 0.060 mg/m(3), the response time of the early warning system is reduced to 0.018 s; (3) The fire probability of "green construction site" will increase significantly with the increase of construction site temperature, and the fire early warning response time will be greatly reduced. When the site temperature is 30 degrees C, the response time of "smart site" fire early warning system is 0.066 s, while when the site ambient temperature reaches 45 degrees C, the response time of "smart site" fire early warning system is only 0.022 s. |
