Indoor fire monitoring based on floor-up view sensing of ceiling

Abstract

In an indoor environment on fire, sensors disposed on, below, or above the floor are automatically deployed to view upward toward the ceiling to observe the body of smoke and flame rising near the ceiling, important information about the state and dynamics of the body of smoke and flame is allowed to be collected at the early stage of the fire (e.g., before the firefighter arrives). By distributing the sensors in the indoor environment, even in the early stage of the fire, the state and dynamics of the body of smoke and flame are monitored as a whole (i.e. As a whole). These information contributes to predicting the development of the fire. In one embodiment, the sensor is held during normal time in an infrastructure sensor holder mounted on a ceiling. When the occurrence of a fire is detected, the sensor falls from the holder, falls on the floor, and orients the sensing direction vertically upward for monitoring. 在着火的室内环境中，自动部署设置在地板上、在地板下方或在地板上方的传感器以朝向天花板向上查看来观察在天花板附近升起的烟雾和火焰的本体，允许在火灾的早期阶段(例如在消防员到达之前)收集有关烟雾和火焰的本体的状态和动态的重要信息。通过将传感器分布在室内环境中，即使在火灾的早期阶段，也会整体地(即作为一个整体)监测烟雾和火焰的本体的状态和动态。这些信息有助于预测火灾的发展。在一种实施方式中，传感器在正常时间期间被保持在安装在天花板上的基础设施传感器保持器中。当检测到火灾发生时，传感器从保持器上落下，落在地板上，并将感测方向竖直地向上取向，以进行监测。
