摘要:随着科技的发展和生活水平的提高,人们对汽车的需求逐年增加,在汽车数量增多的同时,汽车火灾事故的发生几率也呈现上升趋势。汽车火灾事故不仅会给人们造成巨大的财产损失,更重要的是严重威胁着人们的生命安全。传统的汽车火灾探测系统使用单个传感器,探测效率低下,因此,采用多传感器信息融合的方式,可实现对汽车火灾及时、准确的探测与报警。首先简析汽车火灾的发生原因,确定了汽车火灾探测报警系统研究思路,设计了多传感器信息融合的车辆火灾探测报警系统。

Abstract: With the development of science and technology and the improvement of living standards, people's demand for cars is increasing year by year. With the increase of the number of cars, the incidence of car fire accidents is also on the rise. Car fire accident will not only cause huge property loss to people, but also seriously threaten people's life safety. The traditional automobile fire detection system uses a single sensor, which has low detection efficiency. Therefore, the way of multi-sensor information fusion can realize the timely and accurate detection and alarm of automobile fire. Firstly, the cause of automobile fire is analyzed, the research idea of automobile fire detection and alarm system is determined, and the vehicle fire detection and alarm system based on multi-sensor information fusion is designed.

如今,汽车是人们使用最多的出行交通工具,这些年来汽车火灾事故数量在不断增加,由于汽车设备和系统的复杂,使得汽车火灾的探测与报警系统难度较大。多传感器信息融合技术,可从多方收集传感器数据和信息,进行综合处理与分析,获得准确、全面、可靠的信息,以提高汽车火灾系统探测准确性。汽车火灾探测与报警系统主要依据多个传感器来推断是否有火灾的发生,依靠蜂鸣器实现火灾报警。多传感器信息融合的汽车火灾探测报警系统也有助于火灾扑救和预防工作的进行[1]。

1  汽车火灾发生原因

1.1 电气电路故障

是汽车火灾中最常见的一种起火原因,很多时候是因为汽车启动和发动的时候,电气电路发生短路接触不良,之后出现拉弧现象。……
