| With development of railway,safety of train becomes more and more concerned.In recent years,several railway accidents occurred proof that in the field of train control there are few automation equitment to process the speed limit and there are many problems in driving.China has a great number of rails which is very important for the development of national economy.So,keeping safe of therailway transport is of great significance.To achieve control train speed,the train and the ground need to transfer large amounts of information.Speed control system of RFID has high reliability,information capacity,simple structure,flexible installation and easy maintenance,etc.It is very suitable for application in rail transport.However,due to the speed control information is more and more complex;the processing method directly affects the stability and reliability of speed control system.It is necessary to research the method for the processing of speed control.Thesis work focuses on the developing of simulation system of speed control imformation and research of information processing method,including the followings:Firstly,speed control systems are reviewed.The advantages and the problems of importand train speed control systems are analysed.Secondly,speed control information simulation system is designed and developed.This system simulates information of traffic and speed control.Framework,function and significance of the simulation system are introduced.Function,flow and some important code are descripted.This system provides speed control information simulation for testing reliability and stability of the train speed control system.Finally,according to the shortages of some processing method,such as state of train,slope of the rail,target speed and time for reducing the speed are not considered,processing method for continuous speed control is studied.Some experiments on train show that this method is accuracy in normal environment.This method supply correct speed tips and warnings for drivers to ensure train safe in speed control section. |
