The Simulation For Traction And Braking In Train Control Network

Train control network in the running of train plays a very important role, which is responsible for the whole train system of data interaction as the context of train system control.The technology of train control network have been fully developed in foreign,such as Japan. Germany.their trains have been equipped with a complete vehicle-mounted system of train control network. but in our country, the research of train control network is still in the test phase,so it is meanful that to carrying out research on train control network,gain the train network control logic properties,and build a train network simulation system research platform which has independent intellectual property rights.The major objective of this article is not to study traction brake algorithm,but to bulid the model of train.the function of which is for train traction braking process control under the environment of network.and it is based on traction braking and computer network theory.In this paper, the system mainly realizes the functions as follow:firstly,the simution of train control system.in terms of demend of system,to simulit thecontrol of train based on software language(traction control system, brake control system);secondly,the simution of train running,which is based on the threoy of train traction and barking,and choose right model of simution, analysis the stress of train running, and calculate the acceleration in terms of situation;thirdly,to bulid the implementation of train’s internal control logic, in process of train running,how to distribut the stress between the car and how to make the mean of exerting power.the turning of the process of train running,at last we shoug take the order of exerting stress into throught.when train is in the traction.the stress is exerted from last to first,but when braking,it is from first to last;fourthly,realization of the train network communication, the main function of netmork isturning the control order from the center to train.and the svsrem control the Traction Converter or brake to control the running of train.at the same time.the real-time information(speed) of train turn to the center throgth the network.the system can kown the situation as soon as possible.In addition,this system is a subsystem of the platform of train network.it can exchange information with the platform.and provide data to the system,which the system can research the train control network.
