Maglev Train Automatic Protection System

With the development of Maglev technology,the age of Maglev commerce is coming. Maglev as a vehicle,safety is the first target. To insure that,we must design an independent Automatic Train Protect (ATP) system on the train and this system is a part of the Automatic Train Control (ATC) system.In the first part of this page,it discussed some problems of how to planning the velocity curve of train. These problems include:characteristic of line,guideline index of train design,and guideline index of comfort. On the basis of the character of Maglev,it established the logic rule of ATP,and set up the model of ATP.The second part combined the testing line of NUDT,a Matlab software was introduced in detail. By using the software,we can get a optimum velocity curve and other curves,check up the parameters of train and line whether or not satisfy the running require.The third part discussed how to design and realize the software and hardware of ATP. Focused on how to group a PROFIBUS-DP network by PLC,which have two main stations and they can hot back up each other,and the method of malfunction diagnosis on PLC networks. A flow chart of ATP realizing on PLC was given too.The final part calculated all kinds of curves of Ba-Da-Ling tour line,found the design of left line is unreasonable.
