摘　　要：为实现铁路列车设备状态的实时监测,使列车人员方便了解列车运行状况,利用单片机、神经元芯片、Lonworks总线、ARM-linux等技术设计了一种实时的列车网络监测系统。重点描述了监测节点的硬件结构与软件设计,对系统的工作流程和综合监控端的软硬件设计进行了介绍。现场测试结果表明,系统的性能稳定可靠,很好地适用于列车实时监测的需求。To realize the real-time monitoring of the train equipments status,to make it easier for the train person to know about the status of the running train,a kind of real-time train network monitoring system was designed on the basis of MCU,neuron chip,Lonworks bus and ARM-linux technologies. In this paper,the working process of the system and the hardware structure and software design of the comprehensive monitoring terminal were elaborately introduced,especially in the part of the hardware structure and software design of monitoring node. The result of test shows that the performance of this system was stable and reliable ,which meets the real-time monitoring requirements of train.
