基于CTC系统的列车区间交会风险防控方法研究OA

The prevention and control of train section meeting risks has always been one of the key issues in railway transportation safety and a special task that urgently needs to be improved.This paper analyzed actual possible train section meeting scenarios,such as same-direction meeting on adjacent lines,opposite-direction meeting on adjacent lines,and train meetings on multiple adjacent lines.It identified the characteristic points of meeting risks and explored key factors for risk judgment by integrating station yard representation data,stage plan data,train tracking data,etc.The paper optimized the logical structure of the CTC system,created an inter-station transmission and caching mechanism for plan data at adjacent line ports,and opened up the data link for risk criteria.Finally,combined with the in-station route arrangement safety prevention and control strategy of the CTC system,it studied the risk prevention and control methods for train section meetings.Through experiments,the effectiveness,stability,and compatibility with the CTC system of this method were verified,and the results were good.This prevention and control method eliminated train section meeting risks at the railway signal control system level,enhanced railway transportation safety,played a positive and effective role in aspects such as safe technical prevention and control and the improvement of lean and efficient command capabilities,and provided new ideas for the intelligent development of railway transportation safety.
