单线半自动车站接近区段电码化探讨

Discussion of Coding of Semi-Automatic Approaching Sections in Single Track Line

新建玉铁线路速度目标值160km/h,最小曲线半径1600m,为单线铁路,设计方案采用双接近区段,接近区段为1500m,满足速度目标值。目前97型轨道电路叠加ZPW-2000系列电码化最长传输距离为1300m,探讨1500m轨道电路电码化的设置。

The newly-built Yulin--Tieshangang railway is a single-track line with target speed of 160km/h, and minimum curve radius of 1600m. It design adopts double approach sections with the length of 1500m to meet the requirements of target speed. At present the maximum transmis- sion distance of 97 type track circuit with ZPW-2000 series coded is 1300m. So, this paper discus- ses the code setting of 1500m track circuits.
