基于CBTC系统移动授权计算的研究

Based on the research of movement authority calculation of CBTC system

计算机技术、通信技术、微电子技术和控制技术的飞速发展使得利用无线通信传递车地大容量双向信息成为可能,CBTC(Communication Based Train Control,基于通信的列车运行控制系统)正在迅速发展,已逐渐代替传统的列车控制系统。CBTC系统是列车控制系统发展的高级阶段,必须要能够保证列车的安全运行间隔,区域控制器作为CBTC的重要轨旁设备,通过为列车计算并分配移动授权控制列车高效安全运行。对移动授权的定义、计算和分配进行了详细分析,并给出了算例。

Rapid development of computer technology,communication technology,microelectron-ics technology and control technology make it possible to realize high-capacity and double-sided information from train to ground. CBTC（ Communication Based Train Control） systemis developing rapidly,and gradually replaces the traditional train control system. CBTC system is the advanced stage of train control system development,must be able to ensure the safety of the train operation interval,zone controller as an important trackside equipment,CBTC through to train calculation and distribution of mobile authorization control train safe operation efficiency. In this paper,the definition,calculation and distribution of limit movement authority of CBTC system in urban rail transit system are analyzed in detail,and the numerical example is given.
