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.
