摘　　要：近年来,随着粤港澳大湾区的快速发展,区域内城市间客流快速增长,城际铁路对运输效率的要求也越来越高。移动闭塞和自动折返技术是信号系统提升铁路运输效率的重要发展方向,可有效缩短列车区间追踪间隔和折返站折返间隔,从而提高线路的运输能力和效率。目前,移动闭塞技术和自动折返尚未在城际铁路得到运用。根据移动闭塞和自动折返的技术现状,对既有珠三角城际铁路CTCS2+ATO列控系统功能优化的可行性进行深入分析,提出了珠三角城际铁路CTCS2+ATO列控系统实现移动闭塞和自动折返的列控系统总体架构。最后,重点介绍了CCS闭塞方式切换、行车许可计算、自动折返功能优化和折返流程等方面的工作原理。结果表明,在既有珠三角城际铁路CTCS2+ATO列控系统改动较小的情况下实现移动闭塞和自动折返是可行的,对提升珠三角城际铁路线路运输效率具有重要意义。In recent years,with the rapid development of Guangdong-Hong Kong-Macao Greater Bay Area,the passenger flow between cities in the region has increased rapidly,and the requirements for transportation efficiency of intercity railways are getting higher and higher.Moving block and automatic turn-back technology is an important development direction of signal system to improve railway transportation efficiency,which can effectively shorten the tracking interval between trains and the turn-back interval of turn-back stations,thus improving the transportation capacity and efficiency of lines.At present,moving block technology and automatic turn-back have not been applied in intercity railway.According to the technical status of moving block and automatic turn-back,the feasibility of function optimization of existing intercity CTCS2+ATO train control system in Pearl River Delta is deeply analyzed in this paper,and the overall framework of realizing moving block and automatic turn-back in the intercity CTCS2+ATO train control system in Pearl River Delta is put forward.Finally,the working principle and realization of CCS block mode switching,driving permit calculation,automatic turn-back function optimization and turn-back process are introduced emphatically.The results show that it is feasible to realize moving block and automatic turn-back under the condition that the existing intercity CTCS2+ATO train control system in the Pearl River Delta is slightly changed,which is of great significance to improve the transportation efficiency of intercity railway lines in the Pearl River Delta.
