Research And Implementation Of Computer Interlocking Simulation System For Urban Rial Transit

With Chinese increasing investment in urban rail transit,the requirement for interlocking system,which is the core of safety,is more stringent.Due to the lack of interlocking simulation training platform for railway professional students and pre service personnel,the problem of interlocking function is not fully understood.In this paper,a interlocking simulation system based on 3D visual platform for train operation is put forward,which provides a platform for relevant personnel for teaching and research.The system not only has the conventional urban rail computer interlocking function,but also realizes the simulation of the acquisition drive interface,making the interlocking system more complete.On this basis,the communication interface of the 3D visual platform of train running based on MSTS(Microsoft train Simulation)technology is designed to control the 3D dynamic model.At present,in China’s train operation control,the whole CBTC(Communication Based Train Control System)control mode can not be realized,and the corresponding backup mode control vehicle must also be equipped.Referring to the advanced interlocking simulation training system in Chinese market,this paper focuses on the design and implementation of computer interlocking simulation system based on backup mode.According to the functional characteristics of the urban rail computer interlocking system,the system analyzes the interlocking function comprehensively,and adopts the humanized design to make the simulation platform more universal.At the same time,we study the function of the national railway acquisition and drive interface,and simulate it,so that the interlocking system has more training significance.On this basis,the communication interface of the 3D visual platform of train running based on MSTS(Microsoft train Simulation)technology is built to control the 3D dynamic model.Finally,the function simulation test of the system is carried out.The test results show that the simulation work can realize the interlocking function,and can realize the simulation function of the signal equipment and the control of the model of the three dimensional signal machine,and meet the expected requirements of the simulation system.
