摘　　要：针对站间采用64D半自动闭塞的全电子计算机联锁接车站,在列车到达后,操作人员错误先按压闭塞按钮,再按压复原按钮,导致发车站64D半自动闭塞逻辑无法正常复原的问题,对比分析64D继电半自动闭塞电路逻辑与全电子64D模块的半自动闭塞处理逻辑,得出问题产生的原因,提出优化全电子64D模块处理闭塞按钮和复原按钮同时按下的处理方案,解决了接车站两个按钮命令同时按下导致发车站无法正常复原的问题,并对方案进行了测试验证,测试结果表明方案实现的效果符合预期。This paper targets at the problem that the logic of the 64D semi-automatic block system of the departing station cannot be normally reset when the operator first mistakenly presses the block button and then presses the reset button after the train arriving at the receiving station that is equipped with the fully-electronic computer based interlocking and provided with the 64D semi-automatic block system for the inter-station section.It compares and analyses the logic of the 64D relay-based semi-automatic block circuit and the processing logic for semi-automatic block of the fully-electronic 64D module for semi-automatic block,to identify the cause of the problem.An optimized treatment scheme of the fully-electronic 64D module for semi-automatic block is proposed to deal with the case where the block button and reset button are pressed at the same time,which is intended to solve the problem that normal reset cannot be achieved at the departing station when both command buttons pressed at the receiving station,and the proposed scheme is tested and verified.The test results show that the proposed scheme achieves the desired effect.
