The Key Research On Interactive Develop Platform For ATS Simulation System In Urban Rail Transit

Automatic Train Operation is an important part of ensuring the safety of train operation. Automatic Train Supervision is an important subsystem of ATC; ATS’s main role is train supervision and control, supporting the railway station dispatchers to manage the traffic line. For training railway station dispatchers and data testing, it’s needed to simulate ATS system with computer. ATC of different urban rail transit is developed by several different companies, differentiation is exist. The ATS simulation system developed for specific line isn’t universal. This paper is to resolve the reuse problem based on the concept of software development with component. Combining the technology of component and ATS simulation, it will build up a platform, on which the users can develop an ATS simulation system just by assembling component.This paper obtains the development object and requirement analysis by defining the basic function of ATS simulation system. After determining the overall design and modular division, software component technology is used to implement all modules. Component management module is described in detail.Timetable is an integral part of ATS simulation system. This paper describes the generation of timetable. Process is to establish the mathematical model and to solve the model by using ant algorithm. After obtaining the preliminary timetable, process the data balance. In order to reduce the time consuming, using the Hungarian algorithm to optimize the timetable. Experiments show that the timetable can be a good solution to meet the needs of train.After that this paper introduces a prototype of interactive develop platform implemented and the application in the development of universal ATS simulation system. Universal ATS simulation system can demonstration train running status, and to achieve the basic operation of trains.
