既有信号设备增设单线计轴自动闭塞改进方案和试验方法

Improvement Scheme and Test Method of Adding Monorail Automatic Block with Axle Counter on Existing Signal Equipment

基于单线计轴自动闭塞在成昆、成渝、内宜等管段内,作为提高运输能力的设备,大部分在既有设备上增加,施工调试存在许多难点。结合成昆、成渝单线计轴自动闭塞工程的实施,针对新的技术条件,总结技术改进方案,同时对新旧设备结合调试,提供可行的试验方法。

Chengkun railway, Chengyu railway and Neiyi railway have districts of automatic block with single axle counters, and the axle counters are used as equipment to improve transport capacity. Because they need to be added mostly on existing equipment, construction commissioning have many difficulties. Combined with the project implementation of automatic block with single axle counters for Chengkun and Chengyu railways, the paper provides some feasible test methods according to the new technical conditions based on summarizing the technical improvement scheme and conducting commissioning of old and new equipment.
