Research On The Optimization Of Dispatching Command Based On LTE-R 4G Communication Technology

Changing the way of communication to the change of behavior.The evolution of railway dispatching comm and mode is also changing with the developm ent of railway communication mode.Shuohuang railway traffic control system to upgrade the original through wired or wireless di spatching telephone system and fax daily dispatching work m ode of operation,across the Shuohuang railway dispatching work depends on the traditional pen and paper records,phone comm and stage ",using the latest inform ation control and means of communication,to achieve the CTC mode of communication traf fic control and LTE-R 4G wireless communication network.Shuohuang Railway on the basis of central ized scheduling,equipped with 4G LTE-R mobile broadband technology,greatly improve the efficiency and safety of scheduling command.In the LTE-R wireless communication platform,scheduling commands can be tr ansmitted to the locomotive,dispatchers can real-time voice communication with the locomotive driver,confirm the scheduling order,improve the safety and efficiency of train command.In t he LTE-R wireless communication platform,can real-time locom otive and ground station communi cation,to determine the actual position of the locomotive,the locomotive dispatching system of CIR platform and real-tim e communication in the dispatching center can real-time observation of locom otive location and train speed,easy to optim ize transportation organization,real-time adjustment of train operation diagram,and notify the front station traffic organization for in advance,arrangement of receiving departure tasks and shunting operation,so as to enhance the overall ef ficiency of transportation organization.Shuohuang Railway independent research and developm ent of heavy haul train power distribution wire less reconnection control te chnology is also realized through centralized dispat ching and L TE-R wireless com munication platform,synchronous operation of global 10 000 tons of heavy haul train is mostly produced by the U.S.GE LOCOTROL technology,this technology has a high degree of monopoly,the price is expensive.L TE-R wireless communication platform of Shuohuang Railway Construction with co mpletely independent intellectual property rights,relates to locom otive control technology,radio technology,computer and network technology,train braking technology,fault diagnosis and safety oriented technology,the field of train dynamics grow up.Through the hard work of the technical personnel of all pa rties and the technical dem onstration of many times finally reached the advanced technology,equipment stability,driving safety application requirements.
