摘　　要：为解决多种列车监测与控制设备(如LKJ2000、TAX2、TCMS系统)数据集中化处理的问题,在分析列车车载设备接口电气特性以及数据协议的基础上,利用UDP拥塞控制方法提高网络利用率,设计了基于嵌入式Linux+ARM的多通道串口列车监测与控制设备数据采集系统。仿真测试实验表明,该系统能够实时、准确、可靠地采集TAX2、TCMS设备数据,数据采集的准确率可达100%,为实现列车远程监测与故障诊断车载数据采集提供有力支持。In order to solve the problem of data centralized processing of train monitoring and control equipment（such as LKJ2000, TAX2 ,TCMS）, a multi-channel serial data acquisition system of train monitoring and control equipment which run in the embedded Linux system is designed by analyzing the train vehicle equipment interface electrical characteristics and protocol data. Besides, the method of UDP congestion control is been adopted to improve network utilization. Simulation results show that the system can collect the data of TAX2, TCMS accurate and reliable in real time, and the accuracy of data acquisition is up to 100%. The system provides a powerful support for the realization of the data acquisition of train remote monitoring and fault diagnosis.
