绝缘节处无防护信号机时的特殊场景风险分析

Risk Analysis of Special Scenarios at the Insulation Joint without Protective Signal

特殊场景下因无防护信号机的绝缘节存在,致使其所划分的道岔区段不能随进路的办理而锁闭,存在挤岔、掉道、侧冲的风险。通过归纳站内调车作业场景,提出有效识别绝缘节处无防护信号机时的特殊场景,并分析其潜在风险的成因,制定对应修改方案,为今后的工程设计及联锁软件设计提供思路。

In view of the existence of insulation joint without protective signal under special scenarios,which causes that the switch section divided cannot be locked with the setting of the route,and there are some risks of switch squeezing,derailment and flank confliction,lane dropping,this paper summarizes the shunting operation scenarios in the station,proposes a method to effectively identify the special scenarios when there is no protective signal at the insulation joint,analyzes the causes of its potential risks,and formulates corresponding modification plans,which provides ideas for future engineering design and interlocking software design.
