摘要
车载无线传输网关(WTD)技术通过对车辆的实时信息进行采集,处理及发送,使得在地面接收端的信息处理系统能够有效地监控与管理动车组.京沪高铁通信环境的变化对现有WTD技术提出了更高要求.本文通过引入有限状态机技术,类P2P文件传输技术,使得改进后的WTD技术能够在这种新的高速铁路环境下发挥更大的作用.
WTD technology（Wireless Transformation Device Technology） can make ground information system monitor and manage those CRH trains efficiently by collecting,processing and sending real-time information of CRH EMU.For Beijing-Shanghai high-speed railway,higher requirements are brought forward to existing technologies due to changes in communication circumstance.Through improving finite state machine technology and P2P-similar file transmission technology,the WTD can play a greater role under this new high-speed circumstance.
