Design And Implementation Of The Principle Prototype For Low-speed Maglev Train On-board Operation Control System

In China, most of Maglev trains are based on electromagnetic suspension technology. The traction system of the train is on the vehicle, and the main functions of train operation control are performed by the on-board control system.There are many differences between the Maglev trains and the wheel-rail. The Maglev train, whose headway is shorter than wheel-rail, requires highly operation security. The method that control the operation of train based on the ground signal is not fit the Maglev train any more. Therefore, a new and reliable on-board train operation system is needed for the safety operating of the Maglev train.The researches on the on-board Maglev train operation control system are still on the beginning stage in China. The function requirements and the general structure of system of the Maglev train operation control system have not been defined clearly yet. Thus, our works will give some foundation for the building of practical equipment, the works are as follows:Firstly, the working mechanism of Low-speed Maglev Train and the structure of Operation Control System were analyzed, the requirement of on-board Operation Control System was analyzed in detail and based on which a general design of the on-board Operation Control System was given.Secondly, the mode of speed-protection curve was discussed, and calculation formula was given, including the emergency braking curve, common braking curve and train traction curve, by analyzing the physical model.Thirdly, a simulation platform of the on-board Operation Control System was designed based on the Mega162, according to the functional requirement of the system.Fourthly, the debug of the simulation platform was shown to validate the function of the speed-protection.
