Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a model-driven urban rail transit operation simulation method and system. Background technique [0002] With the rapid development of urban rail transit and information technology, communication-based train control system (referred to as CBTC) has been widely used in urban rail transit signaling systems. The extensive application of the CBTC system has effectively shortened the tracking interval of trains and improved the operating efficiency of rail transit. When the CBTC system is put into engineering application, it needs to solve a series of engineering-related design problems. When designing the signal system, it is necessary to determine relevant technical parameters and calculate various technical indicators according to specific engineering conditions. These requirements are not covered in the CBTC system product development process. Therefore, it is necessary to p...

Problems solved by technology

The disadvantages of this solution are: 1) It does not consider the signal system control model, so it cannot fit the control curve of the signal system well, and cannot accurately evaluate the relevant operation indicators; 2) For the design of the signal system, it can only provide a rough running time , running speed and other relevant operating indicators, and cannot provide other parameters required for signaling system engineering design; 3) When designing a signaling system, it is often impossible to provide the input of traditional traction calculation models for locomotive performance, dynamics-related simulation and experimental parameters. The traditional traction calculation simulation cannot meet the application requirements of the signal system

However, the model itself does not consider the calculation model of engineering design-related parameters, and cannot generate engineering design-related parameters, which cannot meet the needs of engineering design
