Abstract: An inserted connection member for a train connector includes an insertion needle, an insulator, a disconnection preventing pad and an extrusion block. The insulator is sequentially provided with a positioning hole and an inserted connection hole in an axial direction. The insertion needle includes a line connecting segment, a positioning segment and an inserted connection segment which are connected sequentially, the line connecting segment and the positioning segment are arranged in the positioning hole. The disconnection preventing pad and the extrusion block are both sleeved on the line connecting segment, and the disconnection preventing pad includes a pad body and a boss arranged on the pad body. Thus, the insertion needle is ensured to maintain a stable contact even when the train is running at a high speed, and a disconnection preventing effect of the insertion needle is achieved.

Abstract: A train driving assistance method includes: pre-setting a train traveling line database (S0); acquiring the position of a train (S1); acquiring the position information about the next early-warning point (S2); calculating an early-warning distance between the train and the next early-warning point according to the position of the train and the position information about the next early-warning point (S3); when the early-warning distance is calculated to be smaller than a pre-set value, displaying the early-warning information corresponding to the position information about the next early-warning point (S4); screening an optimal solution according to the train arrival time information and the number brake times of the train (S5); and determining the driving information according to the optimal solution and displaying the determined driving information (S6). Through the method, more driving reference information can be provided for the driver. Also provided is a train driving assistance system.
Abstract translation: 列车驾驶辅助方法包括:预先设定列车行驶路线数据库(S0); 获取列车的位置(S1); 获取关于下一个预警点的位置信息(S2); 根据列车的位置和下一个预警点的位置信息,计算火车与下一个预警点之间的预警距离(S3); 当预警距离被计算为小于预设值时,显示与关于下一个预警点的位置信息相对应的预警信息(S4); 根据列车到达时间信息和列车的制动次数筛选最优解(S5); 以及根据最佳解决方案确定驾驶信息并显示所确定的驾驶信息(S6)。 通过该方法,可以为驾驶员提供更多驾驶参考信息。 还提供列车驾驶辅助系统。

Abstract: A system and method for testing a network-side harmonic component of a motor train unit, the method comprising: detecting a current of each power unit, sampling and quantifying the detected current, acquiring a digital current signal of each power unit, superimposing each digital current to obtain a current of the entire train, and acquiring a harmonic component according to the current of the entire train. A sample frequency is determined according to a frequency and a target phase angle error of the harmonic component to be detected. The provided system and method for testing the network-side harmonic component of the motor train unit improve a detection accuracy of harmonic current and can detect the harmonic component at a frequency above 3000 Hz.
