提速干线自动闭塞及列车超速防护的研究

Study on the Automatic Block and Train Over-speed Protection on the Fast-speed Main Lines

对我国干线铁路提速后的自动闭塞及列车超速防护的系统设备、制式的选择及其实现手段、信号显示制度的改革等方面的问题进行了研究探讨。提出了三显示自动闭塞制式仍可满足提速要求,超速防护应采用模式速控方式和以常用制动为主的方式,现有自动闭塞设备仍可继续使用等论点。

The paper discusses the instruments, systems and implementation measures of the automatic block and train overspeed protection on increased speed main lines and reform of signal aspect system. It puts forward that the 3-aspect automatic block system can satisfy the increasing speed requirements and model stepped speed and service braking as the main braking force will be employed in overspeed protection. It considers that the existing automatic block equipment can remain in operation.
