在保障列车行驶安全性的基础上,基于通信的列车控制技术能够极大地提升列车行车速度,进而满足城市轨道交通中对列车快速行驶的要求。目前,无线通信的理念和移动闭塞技术,可以达到我国城市轨道交通中的控车要求,符合我国城市轨道交通发展目标。本文以列车控制中的关键技术为研究对象,从基于通信的列车控制技术的系统结构、移动闭塞以及基于通信的列车控制技术中的车-地通信技术三个方面进行详细论述。
On the basis of ensuring the safety of train driving, the train control technology based on communication can greatly improve the train driving speed, and then meet the requirements of rapid trains in urban rail transit. At present, the concept of wireless communication and mobile blocking technology can meet the control requirements of urban rail transit in China, in line with China’s urban rail transit development goals. In this paper, the key technology of train control is taken as the research object, and the system structure of train control technology based on communication, mobile blocking and vehicle-ground communication technology in train control technology based on communication are discussed in detail.
