摘要
对婺源站跨场运行时,因移频轨道电路区段长度不足而导致动车制动问题进行深入分析,提出将移频轨道电路的发码时机与列车运行方向关联,使该区段的轨道电路有条件发码的特殊处理方案,巧用继电电路的小修改解决列控系统问题,避免列控软件修改,节约问题解决的时间及成本,该思路值得后续解决类似问题参考借鉴。
The case of abnormal EMU train braking during cross-yard operation due to insufficient length of the frequency-shifted track circuit section in Wuyuan Railway Station is analyzed.A solution is proposed to link the timing of code transmission in the frequency-shifted track circuits with the direction of train movement and to make the track circuit section send code information based on conditions.A creative modification scheme of the control relay circuit is introduced to solve the problem of abnormal EMU train braking,avoiding the modification of the train control center software and saving construction period and cost.It can provide significant reference for related problems.
