摘　　要：文中提出了一种利用WSN(无线传感器网络)技术,结合多传感器数据融合技术、信息处理以及嵌入式技术,对地铁车辆车载设备的火灾状态进行识别报警的设计方案,实时监测火灾的发生,提高地铁运行安全性。文中着重对传感器的选型、系统的硬件软件以及WSN组网方式进行了详细设计。实验结果表明,系统运行状况良好,信息传输准确可靠,对潜在的火情能及时报警。在实际地铁环境中,列车车载设备报警温度测量值的最大误差不超过0.4℃.This paper puts forward a design scheme in which the system recognizes the fire conditions of subway vehicle devices by means of WSN（ Wireless Sensor Network）, Muhi-sensor Data Fusion, Information Processing and Embedded Technology, and it issues alarm in time. The system monitors subway fire in real-time, so as to improve the safety of subway operation. This paper emphasizes the detailed design of sensor selection, hardware and software as well as WSN （Wireless Sensor Network） networking method. Experimental results indicate that the system runs in good condition and information can be accurately and reliably transferred. Meanwhile, it is able to give an alarm about potential fire conditions of subway vehicle devices in time. In the actual subway environment, it is tested that the maximal error of temperature measurement for fire alarm of subway vehicle devices is less than 0.4 ℃.
