Research on the transformation project of key equipment for through operation of existing lines of urban rail transit
With the rapid development of network of urban rail transit operation mileage in China,the rail transit network in many cities has exposed the issues of high interchange pressure,insufficient resource sharing,service level to be improved and unbalanced distribution of capacity,etc.The transformation to through operation is a favorable means to solve the above issues.This article starts from the key equipment of urban rail transport,and systematically puts forward the transformation technology of key equipment for through operation of existing lines.Taking the existing lines as the research object,it clarifies the goal of realizing through operation,and elaborates on the upcoming reform era of urban rail transit and the necessity of through operation.Subsequently,it summarizes and analyzes the transformation principles of each key equipment system.Then,the key equipment systems,such as vehicles,platform gates,power supply,communication,signaling,dispatching,and command are studied in depth,and the technical key points of transformation and corresponding technical means under different working conditions are discussed.Finally,taking the key equipment transformation schemes for through operation between the Fangshan line,and line 9 as well as the Yizhuang line,line 5,and line 10 as examples,a set of key equipment transformation technology system for through operation of existing urban rail transit lines is initially formed,with a view to provide technical guidance for the subsequent transformation of through operation of existing urban rail transit lines in various places.
