Performance analysis on synchronous control of Da-Qin heavy-haul railway locomotives

摘要

The key to safe operation of heavy-haul combined train is whether the train can be operated and controlled synchronously. In this paper, the model of GSM-R wireless transmission system on Datong-Qinhuangdao (Da-Qin for short in the following paper)heavy-haul railway and failure and recovery model are established based on DSPN. The result of simulation by TimeNet4.0 shows that the probability of data transmission delay less than 1s under Da-Qin railway wireless transmission system can meet the requirement of QoS. We analyze the influence in transmission from the operating speed. Under the assumption that two-way transmission of brake wave has the same speed and neglect the impact on brake wave velocity caused by the air load difference of locomotive. The transmission of the brake signal can also meet the safe operation of heavy-haul train.
