摘要: 针对快递货车火灾事故频发的现象,论文设计了货车火灾报警及灭火系统。该系统将 传感器(包括温度传感器、红外火焰探测器、烟雾探测器)与报警器、CO2 气瓶相结合,通 过感应货厢内部不同位置温度变化、烟雾浓度变化、是否有明亮火光出现等火情隐患相关信 息,将潜在火灾危险及时反馈给货运驾驶员以及货车外部的人与车辆,同时 CO2 气瓶开始工 作,对着火位置进行灭火处理。运用数值模拟方法确定各类传感器的布置部位,并制作货车 火灾报警系统的缩尺模型进行了实验。研究成果为真实货车火灾报警系统提供思路,填补目 前快递行业在运输安全方面存在的漏洞与缺陷。

Abstract: Aiming at the frequent fire accidents of express freight cars, the freight car fire alarm system is designed. The system combines sensors (including temperature sensors, infrared flame detectors, and smoke detector) with alarms CO2 cylinder, the potential fire danger is communicated to the truck driver and the people and vehicles outside the truck by sensing the temperature change, smoke concentration change and whether there is a bright fire light. The position of all kinds of sensors is determined by numerical simulation method, and the scale model of truck fire alarm system is made, at the same time, the CO2 cylinder began to work to extinguish the fire. The study provides the train of thought for the real freight car fire alarm system and fills up the loopholes and defects in the transportation safety of express industry.
