Real-time acquisition system, real-time acquisition equipment and real-time acquisition method for three-dimensional fire scene information

Abstract

The invention provides a real-time acquisition system, real-time acquisition equipment and a real-time acquisition method for three-dimensional fire scene information. The real-time acquisition system comprises a main body structure which can be connected with the inner wall of the upper part of the space; the trigger is connected to the main body structure to be started according to the surrounding environment condition; and an outer cover connected to the main body structure and the trigger and peeled off according to triggering of the trigger, in which a sensor string is disposed, including a plurality of sensors sequentially connected in series through a flexible wire to sense characteristic information of an ambient environment, and in a compact state in which the flexible wire contracts when not activated, when started, the plurality of sensors are in an extension state in which the flexible wire is extended, so that the plurality of sensors are hung down at certain intervals; and the transmission module is connected to the main body structure and connected with the upper end of the sensor string, and is used for collecting data from the sensor string and transmitting the data to a server. The system can provide higher reliability by transmitting real-time fire scene data, and provides important basic information for fire evolution prediction. 本发明提出三维火场信息的实时采集系统、实时采集设备和实时采集方法。实时采集系统包括主体结构，能够与空间的上部内壁连接；触发器，连接至主体结构以根据周围环境情况启动；外罩，连接到主体结构和触发器，根据触发器的触发而被剥落，外罩中设置有传感器串，包括通过柔性线依次串联地连接的多个传感器以感测周围环境的特性信息，在未启动时处于柔性线收缩的紧凑状态，在启动时处于柔性线伸长的延展状态以使得所述多个传感器彼此间隔一定距离垂下；传送模块，连接到主体结构并且与传感器串的上端连接，采集来自传感器串的数据并传送到服务器。系统可通过传输实时火灾场景数据，提供更高的可靠性，为进行火灾演化预测提供重要的基础信息。
