| Vehicle diagnosis and control system plays 'an important role in the meglev train. It realizes the central functions such as equipments online supervision, fault diagnosis, central control and regulating in the maglev train.Based on the discussion of some kinds of diagnosis and control systems in high-speed railway especially the German high-speed maglev train on Shanghai, the compose of diagnosis and control syetem in Meglev train is presented.Then, Some measure to improve performance for the system was mentioned.Finally,a plan of Vehicle diagnosis and control system was brought forward. Ulteriorly, hardware choosing and programming for SDR is detailed. In addition, a debugger for suspension control system on train was introduced, which has been validated in experiment.At first, The paper introduces the progress that is made in measure-control system field home and out, and realizes the request of safety, reliability and realtime control. Secondly, the thesis discusses in the fieldbus system and the corresponding network in train.Especially, detailed explanation about RS-485 bus and CAN (Control Area Network) bus.After studying in the functions, architecture, signal flew etc in maglev train, the practice put forward to some scheme more safely and more agility. Through compiled a programe use to SDR based on TC and choose a kind of computer system founded gained two para in three .A set of system is completed triumphantly used to control the para which decided the performance in the train's suspension.By the way, the system is realized through two ways. |
