汽车整车火灾试验视频监控系统的设计应用

Design and application of video monitoring system for complete vehicle fire experiment

在汽车火灾原因调查的过程中,通过汽车燃烧蔓延痕迹的分析确定起火部位、起火点是认定汽车火灾原因最关键的步骤。而对火灾痕迹特征准确辨识的前提是对火灾燃烧特点及蔓延过程的熟悉和了解。通过自主研发的全方位同步视频监控系统,采集汽车火灾蔓延过程中火焰、烟气的蔓延途径和关键时间节点,为分析研究汽车火灾蔓延痕迹特征,从而确定起火部位、起火点提供有力的技术支持。

In the process of investigating the cause of vehicle fire,the most important step is determining the fire location and ignition point based on the fire spreading trace analysis.The premise of accurate identification of fire trace features is to be familiar with the characteristics and spread process of fire.This paper collects the propagation path and key time nodes of the fire and smoke in the process of vehicle fire spreading through the omni-directional time synchronization video monitor system developed by ourselves.It analyzes and studies the characteristics of vehicle fire spread traces,and provides effective technical support for identifying the fire location and ignition point.
