中韩自主化全电子联锁系统对比研究

Comparative Study on Indigenous All Electric Interlocking Systems between China and South Korea

与传统的继电器接口方式相比,全电子执行单元具有灵活配置、节约成本、节省空间、调试安装方便等诸多优点,成为计算机联锁系统的发展趋势之一。从系统架构、通信协议、系统实验3个环节,对中韩两国自主化全电子联锁系统的研究进展进行对比分析。通过对比发现:韩国的全电子联锁系统主要借鉴欧洲铁路的EULYNX标准框架,应用于铁路干线;中国全电子联锁系统目前在城市轨道交通线路和部分场段有所应用,在铁路干线正处于实验阶段,可借鉴韩国全电子联锁系统的经验。二者在系统架构、通信协议方面采用安全可靠的措施保障系统的安全,最后通过实验室和工程现场试验,验证系统的可行性。

Compared with the traditional method using relay interface,the all-electric execution units have many advantages,such as flexible configuration,cost saving,space saving,and easy commissioning and installation,and have become one of the development trends of computer interlocking systems.The research progress of indigenousall-electric interlocking systems in China and South Korea was compared and analyzed from three aspects:system architecture,communication protocol,and system test.Through comparison,it was found that the all-electric interlocking systems in South Korea mainly follow the EULYNX standard framework in the European railway,mainly used in the main line;the all-electric interlocking systems in China are currently used in the urban rail transit lines and some depots,and is in the experimental phase in the main line,so as to learn from the experience of South Korea.Both systems use safe and reliable measures to ensure the safety of the system in terms of the system architecture and communication protocol,and verify the feasibility of the system through laboratory and engineering field tests.
