为了识别全自动运行线路接发车过程中站台门控制电路可能存在的安全风险，通过对控制自动接发车条件的站台门控制系统相关外部接口控制电路、内部“门关闭并锁紧”状态安全回路、就地控制盒工作模式的分析，同时结合站台门控制系统的结构和控制方式，剖析现有电路特别是站台门就地控制盒电路设计在全自动运行应用中可能存在的风险，根据识别出的风险给出了全自动运行线路站台门就地控制盒电路既有电路的利弊分析和改进方案设计，在兼顾安全和运营效率的前提下，给出了适用于全自动运行线路的建议方案。

In order to identify the possible safety risks in the platform door control circuit during the receiving and departure of the fully automatic operation line, through the analysis of the relevant external interface control circuit of the platform door control system that controls the automatic receiving and departure conditions, the internal "door closed and locked" state safety circuit, and the working mode of the local control box, and in combination with the structure and control mode of the platform door control system, This paper analyzes the possible risks of the existing circuit, especially the circuit design of the platform door local control box, in the application of fully automatic operation, and gives the advantages and disadvantages analysis and improvement scheme design of the existing circuit of the platform door local control box circuit of the fully automatic operation line according to the identified risks. On the premise of considering the safety and operation efficiency, it gives the recommended scheme suitable for the fully automatic operation line.
