track switch

With the railway passenger dedicated lines constructed fast, China Railways High-speed electric multiple units localized, the development of speed-lift switch and technology continues welded track, control way relying on traditional artificial experience and not intelligent enough which need to be improved urgently.

随着客运专线的快速新建，和谐号动车组的国产化，提速道岔及无缝线路技术的发展，传统依靠人工经验和不够智能的控制方式亟须得到改善。

Train track occupancy recognition is to determine if the train is passing over a switch and to supply reliable information for train positioning system and train control system.

列车轨道占用识别目的是在平行的多轨道区域识别列车所占用的轨道信息，为列车定位子系统或控制系统提供可靠的信息。

After assembly, operation of the portable tester is on a normal track. It can be conveniently used to accurately measure the control cubicle electrical switch. On September 25, 2007, it successfully went through the evaluation and examination by the Shanghai Railway Bureau.

测试仪组装完毕之后，运行正常，使用方便，可准确的测试控制柜电器开关，于2007年09月25号，顺利通过上海铁路段评审。

The Experimental Research of the Automatic Track Switch of the Road Railer

卡轨车自动道岔试验研究

Three general models, coupling high-speed rolling stock and track system running through a switch, are established considering the elasticity of track foundation and bogie frames.

建立了考虑线路弹性及把转向架构架视为柔体的高速车辆/线路系统通过道岔运行的三种通用模型。
