为了解决目前客车发动机舱内火灾预警装置检测时间较长、误报较多的问题。在分析客车火灾成因的基础上，以客车发动机舱为研究对象，设计客车热表面故障模拟实验平台，模拟行车过程中的热表面故障，通过多个温度传感器采集热表面故障时舱内温度数据，基于温度故障特征开发了一种火灾识别预警试验系统。实验结果表明：基于舱内温度变化故障特征的判别方法，能够准确对客车火灾进行早期预警。

The current fire detecting device in engine compartment of passenger coach is criticized for its long detection time and more false alarms.In order to solve these problems,this paper analyzed the causes of passenger coach fire were analyzed in this paper.Then based on them,the hot surface fault simulation experiment platform was built and the hot surface fault in the driving processing was simulated.When the hot surface fault was occurred,the temperature dates in the compartment were collected by multiple temperature sensors.Based on temperature fault characteristics,a fire recog-nition and early warning test system was developed.Many experimental results showed that the discriminant method based on fault features of the temperature change in the compartment could effectively give a warning in the early stage of passenger coach fire.
