Research And Development Of High Speed EMU Automatic Driving Technology

With the reform and opening up of the people’s Republic of China,the process of urban-rural integration construction has been further deepened and accelerated,people’s daily life and demand for travel services have been further increased,and people’s requirements for travel safety have been strengthened.So when the high-speed railway is facing the challenge of full automation,the further expansion and rapid development of the train control system has become more urgent.It can not only fully meet the basic technical requirements of the interconnection between the intercity high-speed railway and the existing national railway trunk high-speed railway,but also meet the basic technical requirements of the high-density and public transportation of the intercity high-speed railway,which is of great strategic significance to further improve and develop the technology of the train control system of China’s high-speed railway.ATO system is the abbreviation of an automatic control system that automatically controls the automatic and accurate operation of current trains.It is widely used in urban rail transit lines with high density of automatic control driving distance,high precision of parking and positioning,frequent start-up or suspension of trains,such as Shanghai and Beijing urban rail transit.ATO system,based on the current train related information automatically provided by current train ATP and ATC system,under the supervision of current train ATP automatic operation protection and system,according to the current train’s accurate operation speed,target train operation distance,line operation speed limit,etc,At the same time,under the premise of ensuring the maximum comfort of the current train,it can effectively realize the accurate operation of energy saving and environmental protection for the safe operation of the current vehicle.The ATO system foundation has all the basic information and relevant data about the layout of the accurate operation track of the current train and the operation gradient of the train,so that the system personnel can optimize the accurate operation control command of the current train in time.
