The Research And Implementation Of Train Collision And Early Warning System

In recent years,the rapid development of China's railway transportation,Chinese high-speed rail technology is already among the world's advanced level of similar techniques.Our railway construction also continues to progress along the railway transportation speed,convenience is at an unprecedented high-speed development of the situation forward,and has begun to export to other countries,a representative of our country industry.However,the rapid development of rail transportation technology,transportation safety and security is inseparable from the support of the related art,high-speed rail accident in recent years is a wake-up call,a new railroad run collision monitoring and early warning mechanisms need to be urgently established.Aiming at this problem,and implemented a train collision monitoring and early warning systems.The railway system from the basic problem modeling point of view,the establishment of which is suitable for high real-time monitoring and early warning of collision expression model railroad;on this basis,designed a variety of positioning technology based on the fusion of train positioning technology;based on accurate and reliable positioning technology,the paper implements two train collision monitoring and early warning method capable of simultaneously based on short-range communication between the remote and the train are two ways to provide train collision monitoring and early warning service,to improve monitoring and early warning of train collision Ability.In this paper,the system needs analysis,outline design and detailed design,key technology research,system implementation has done a detailed explanation.The simulation results of this test proves the correctness of the system.
