Design And Implementation Of Maglev On-board Safety Protection And Control Simulation System

Maglev transportation,which provides high reliability,high efficiency, high density solution means for the issue of urban traffic congestion,is the new milestone of the development of the traffic history.The maglev operation control system, which is the maglev train's "brain and nerve",plays a vital role in guaranteeing the safe operation of maglev train.At present,internal maglev operation control system technology is very backward,so it is necessary to carry out the research of operation control system.Based on the application of the Shanghai high-speed maglev,the operation control system of the German high-speed maglev traffic was focused on by the article.Then functional requirements of the maglev on-board safety protection and control system were analyzed.And the structure and function modules of system were designed and on-board safety protection and control simulation system was developed.Finally the simulation system was debugged and functions were verified.Research work in this thesis is focused on the followings:Firstly,the development of magnetic suspension technology and the status quo of magnetic suspension technology at home and abroad were summarized.The structures and functions of the German high-speed maglev operation control system were analyzed, and the structures and functions of the vehicle operation control system were studied.Secondly,elements of high-speed maglev train were analyzed and functional requirements of maglev train on-board security protection and control system were ascertained based on research of high-speed maglev operation control system.Then the structures and functions module of simulation system were designed.Thirdly,based on analysis of the functional requirements of the function execution unit,hardware circuit board with control,collection and communication function and software with speed-protected curve,on-board control and communication function were developed.Fourthly,software with driver control interface,speed-protected curve interface, on-board control unit interface,movement model of train and communication function were developed based on the analysis of functional requirements of manipulate display computer and design of function module.Finally,the external operation environment for simulation was constructed and software and hardware of system were debugged.Then the maglev train on-board security protection and control simulation system was debugged joint and function of simulation system was verified.
