Research On Train-ground Wireless Transmission System Based On WLAN

The railway train,which provides convenience for people to travel,is development quickly.The whole system of the train is large and complex and normal stable operation is absolutely vital for it.In order to maintain the train more efficiently and quickly,a train-ground communication system was designed in this paper.In this system we designed,the data of the train could be transferred to ground where the professional staff was on hand.After the maintainable staff diagnosed and find the potential problems by the data they received,and then they could make a plan for the work ahead of the time.In this way,the service working efficiency and quality comprehensively are improved greatly.In this paper,the train-ground communication system was designed and illustrated,which is organized into three parts: vehicular network and wireless communication network and ground network.The vehicular network gather the information of the train by the WTB+MVB.The information,such as statues and value and hitches,could be sent to vehicle wireless device by real-time Ethernet communication protocol.The data of the train was transmitted to ground network server through the vehicle wireless device and the server store the data.The staff of the train could access server and analysis these data by the software,making they were shown in corresponding interface.Finally,constructed the experimental platform and then this system was tested through the data of the line 3 excellent rail of the Dalian.Results from this train system test show the client computer could show the train states clearly and the network parts of the system are working properly,which can realize the functions anticipated.
