摘要
电动汽车属于汽车行业的支柱产业,越来越受到社会的重视,但随之产生的汽车安全问题也逐渐增多。电池舱属于复杂环境,易出现着火事件,本文开展多传感器融合车载电池舱灭火方法研究,运用温度、烟雾浓度传感器实现对火灾的实时监测。设计贝叶斯网络模型,并考虑到了传感器失效及误报,实验结果表明本系统具有良好的响应速度及稳定性,为相关领域研究提供了一种解决方法。
Electric vehicles is an important part of the automobile industry,and are increasingly valued by the society,but the resulting automobile safety problems are gradually increasing.The battery compartment is a complex environment and is prone to catch fire.In this paper,a multi-sensor fusion vehicle battery compartment fire extinguishing method is researched,and temperature and smoke concentration sensors are used to realize real-time monitoring of fire.The Bayesian network model is designed,and the sensor failure and false alarms are taken into account.The experimental results show that the system has good response speed and stability,and provides a solution for research in related fields.
