Study On Urban Rail Transit Intelligent And Integrated Dispatch Manage System

To develop the URT (Urban Rail Transit) mainly including metro and LRT (Light Rail Transit) is the important way to resolve urban traffic jam. Currently China has entered into the period of urban rail transit's rapid development,but because we are in the phrase of construction, the research on the urban rail transit mostly concentrate at line plan, design and construct, the research on train operation dispatch and management aspects is comparatively less. Along with the continuously accomplishment of new lines and put into service,the network of urban rail transit come into being gradually,henceforth the hot problem will focus on URTDMS(Urban Rail Transit Dispatch Manage System).URTDMS is the important content to guarantee train safety and punctual operation, which importance is obvious. To improve the efficiency while insure the train safety is the topic of URTDMS forever. Under normal circumstance the train operation is dispatched according to train diagram, but when the exceptional instances happen, such as train delay, unexpected change of passenger flow or the occurrence of all kinds of malfunctions and calamities and so on,how to adopt effective measures,deal with the various unexpected cases in time and create the reasonable train adjustment, in the same time, how to resolve the existing automation islands of URT to realize all the sub systems to share the information and linkage control, which are all the realistic problems. To discuss on these problems is helpful to advance the rightness and rationality of URTDMS, to alleviate the working intensity and to have the important signification on theory and reality, all of which is the target of this dissertation.There are five main aspects, which are studied details in the dissertation presented as following:(1) Based on the analysis of intelligentized and integrated trend of URTDMS, the dissertation presented the goal to establish the URTIIDMS (Urban Rail Transit Intelligent and Integrated Dispatch Manage System). The dissertation encloses how to realize intelligence and integration of URTDMS. From the view of intelligentized,the key point of URTDMS to intelligentize is to have the intelligent dispatch function under the nonnormal situation. The scheme of URTDIDSS (Urban Rail Transit Dispatch Intelligent Decision Support System) is brought forward. The theory of the CRB (Case-based reasoning) and RBR (Rule-based reasoning) technique in the fields of AI (Artificial Intelligent) is introduced into the design of the accident disposal sub system. From another view of integration, in order to aim at the requirement of all the sub systems to share the information and linkage control, the integrated information platform is introduced, which will increase the transit efficiency, improve service quality and enhance response ability under an emergency.(2) Based on the modeling the URT, the mathematic description is introduced and train's movement rule isanalyzed. The causations of train delay and the influences are discussed, at the same time, concerned with the delay of leaving station occurring for the trains staying time beyond scheme in daily operation, on the basis of making researches...
