【摘要】：随着通信技术、计算机技术、和控制技术(3C技术)的飞速发展,城市轨道交通的建设热潮,基于通信的列车控制系统(CBTC, Communications-Based Train Control)得到了广泛的应用,成为列车运行控制系统的发展趋势。对于CBTC列车控制系统而言,联锁系统是保证列车运行安全不可或缺的核心安全子系统之一,联锁的主要任务是负责列车安全运行的底层逻辑防护。国内对于CBTC系统的研究起步较晚,CBTC技术的被国外信号厂商垄断,限制了国内城市轨道交通的发展。因此,消化国外研究成果,开发具有自主知识产权的系统是非常紧迫和意义重大的。本文以CBTC系统为研究背景,以联锁逻辑设计为研究目标。分析CBTC系统特点和CBTC后备系统设置,研究CBTC模式下区域控制器与联锁系统的关系,对比CBTC模式和后备模式下联锁的功能要素区别,提出基于CBTC系统的联锁子系统需求,在此基础上,划分联锁系统的主要功能模块,确定每个功能模块的具体的逻辑功能。在设计中,采用布尔函数表达式完成主要功能模块的联锁逻辑编写以及联锁系统内部的中间辅助逻辑变量的逻辑编写,完成部分逻辑变量的缓吸缓放属性的定性设计。最后,以郑州一号线为设计对象完成满足CBTC系统及混跑模式下的整条线路的联锁逻辑编写。此外,根据CBTC系统特点以及基于CBTC系统的联锁逻辑部分的设计,定义联锁与其他子系统的功能性接口,包括联锁与ATS、LCW、ZC、现地以及相邻联锁系统的接口,实现接口部分设计。最后,借助实验室ATS仿真测试平台,在列车模拟子系统和现地模拟子系统的协作下,以实际线路数据为依据,对设计的联锁逻辑进行测试。
[Abstract]:With the rapid development of communication technology, computer technology and control technology (3C technology), the construction of urban rail transit upsurge, the communication based train control system (CBTC, Communications-Based Train Control) has been widely used. It has become the development trend of train operation control system. For the CBTC train control system, the interlocking system is one of the core security subsystems to ensure the train operation safety. The main task of the interlocking system is to take charge of the underlying logic protection of the train safety operation. The research of CBTC system started late in our country, and the CBTC technology was monopolized by foreign signal manufacturers, which restricted the development of domestic urban rail transit. Therefore, it is very urgent and significant to digest foreign research results and develop systems with independent intellectual property rights. This paper takes the CBTC system as the research background and the interlocking logic design as the research goal. This paper analyzes the characteristics of CBTC system and the setting of CBTC backup system, studies the relationship between area controller and interlocking system in CBTC mode, compares the functional elements of interlocking between CBTC mode and backup mode, and puts forward the requirement of interlocking subsystem based on CBTC system. On this basis, the main function modules of the interlocking system are divided, and the specific logic functions of each function module are determined. In the design, Boolean function expression is used to complete the interlocking logic of the main functional modules and the intermediate auxiliary logic variables in the interlocking system, and the qualitative design of the slow absorption and release properties of some logic variables is completed. Finally, the interlocking logic of the whole line under the CBTC system and the mixed running mode is compiled with Zhengzhou Line 1 as the design object. In addition, according to the characteristics of CBTC system and the design of interlocking logic part based on CBTC system, the functional interface between interlock and other subsystems is defined, including the interface between interlock and ATS,LCW,ZC, locale and adjacent interlocking system. Implementation of the interface part of the design. Finally, with the help of the laboratory ATS simulation test platform, under the cooperation of train simulation subsystem and local simulation subsystem, based on the actual line data, the designed interlocking logic is tested.
