摘要
介绍了上海地铁车辆火灾状态识别系统的课题背景和研究目的，着重分析了地铁车辆大功率用电设备的工作原理与发热原因。设计了基于CAN总线和单总线二层网络的火灾状态识别系统硬件结构，对传感器选型、安装位置、报警阈值以及系统通信协议、信号内容、数据流向等方面进行了一定深度的研究。使用VB．NET编程语言，在Windows CE．NET嵌入式系统下完成了软件设计和实验验证，给出了火灾状态识别系统的运行结果。
it introduces the background and purpose of fire-identify system for the subway of shanghai ,mainly analyzes the work principle and the cause of heat of the high-power electrical equipments, the network structure of fireidentify system based CAN and one-wire communication protocol is designed. It studies the types, position, alarm value of the sensor and the network message, data flow of the system, software for fire-identify system with Visual Basic.NET based Windows CE.NET embedded system is given out,the exam of system have been carried out,running interface and conclusion of the test are also presented.
