摘要:
当前,在CRH2 型动车组运营过程中ATP 自动过分相网络控制策略缺陷导致牵引封锁的情况时有发生,对列车运营安全带来了极大风险。为此,文章提出了一种改进型的网络控制策略:当短编组重联运行时,远编组的分相区间长度累加计算不再根据车次有效进行判定;增加干扰及非主控端过分相信号过滤机制,避免非法执行过分相控制;当短编组重联运行时,若实际分相区间长度小于阈值(200 m)而无法进行出过分相控制时,采用出分相信号下降沿时进行运行里程200 m 累计后强制出分相控制策略得以解决。通过该组合优化策略解决了对不同运营工况的适用性问题,提高了网络控制系统的稳定性与可靠性,保证了列车运营安全。最后,通过测试台测试及现场装车运行验证了该策略的有效性,同时模拟各种异常运营场景进一步验证了其稳定性及健壮性。
Abstract:
At present, the ATP auto-passing neutral section control strategy defect in the operation process of the CRH2 EMU has caused the traction blocking, and it introduces great risks to train operation safety. In this paper, an improved network control strategy was proposed to solve this problem. The main improvement point is to change the strategy of the length calculation so that the length calculation of the phase separation interval of the far group is no longer determined according to the effective number of trains when the short group is rejoined. By increasing the filtering mechanism of interference and non-master over-phase signal, the proposed mechanism avoids illegal execution of excessive phase control. When short groups rejoin the operational organization form, if the actual phase separation interval length is less than the threshold (200 m), the phase separation control cannot be performed, 200 m accumulation is performed when the falling edge of the split phase signal is used. Through the combination optimization strategy, the proposed scheme solves the applicability of different operating conditions, improves the stability and reliability of the network control system, and guarantees the safety of train operation. Finally, the effectiveness of the strategy is verified by the test bench and on-site loading. At the same time, various abnormal operating scenarios are simulated to further verify its stability and robustness.
