Mechanism And Application Research On The Prevention Of Squeeze Turnout Accident Based On Route Control

Safety is always the eternal topic of rail transport, railway undertakings grand goal cannot be achieved without the security assurance. China’s railway industry is in the process of rapid development, at this stage, more attention should be paid to safety of rail transport. The station has been plagued by three inertial accidents, shunting of derailment, squeeze the fork and the conflict, in addition, crowded fork accident accounts a high proportion, which requires more attention and concern.In this paper combined with the existing station interlock system, cab signaling, route control process and analyze large amounts of squeeze fork accident occurred, mainly due to the shunting operation and non-coding region work, machine control measures’ lacking, the vehicle cannot receive signal of if it is safe to enter, instead to rely on manual confirmation signal. On another hand, the concentration lacking of human being happens all the time, it is difficult to avoid the violation of operating standards and acting on speculation. In this context, improve the management level, the development of more sophisticated operating standards for the prevention of the fork to squeeze accident achieved little success, it is necessary to increase some of the equipment, the turnout opening the correct information to the vehicle.(in order to deliver the correct information of turnout opening)On another hand, through the analysis of turnout control circuit, the turnout in which the state can fall through the relay pick up reflected. At the same time set a detection (to affirm the vehicle running direction and turnout to pass are same) means for detecting a vehicle after running direction and through turnouts are the same, two conditions common control signal transmitter ability to send the signal to the vehicle, the vehicle can be stopped in front of the incorrect turnout.Anti-squeeze bifurcated device can have a variety of designs, this article only provides a vision and concrete, has a certain reference value.
