Data communication method and device

Abstract

本发明公开了一种数据通信方法和装置,其中通信方法包括:第一车载无线网关或第二车载无线网关接收车载用户发送的第一数据报文;并对所述第一数据报文添加第一报文控制头,得到第二数据报文;第一车载无线网关或第二车载无线网关向地面通信网关发送所述第二数据报文;同时第一车载无线网关或第二车载无线网关通过心跳数据线向对方车载无线网关发送所述第二数据报文,以使对方车载无线网关向所述地面通信网关发送所述第二数据报文。而地面无线网关将数据报文最后发送给地面用户。本发明能够解决现有车载监测信息通用传输平台系统中存在的缺少无线冗余链路的问题。
The invention discloses a data communication method and device, and the method comprises the following steps that a first vehicle-mounted wireless gateway or a second vehicle-mounted wireless gateway receives a first data message sent by a vehicle-mounted terminal, adds a first message control head to the first data message, and obtains a second data message; the first vehicle-mounted wireless gateway or the second vehicle-mounted wireless gateway transmits the second data message to a ground communication gateway; meanwhile, the first vehicle-mounted wireless gateway or the second vehicle-mounted wireless gateway transmits the second data message to an opposite vehicle-mounted wireless gateway through a heartbeat data line, so as to enable the opposite vehicle-mounted wireless gateway to transmit the second data message to the ground communication gateway. and finally the ground wireless gateway transmits the data message to a ground user. The method can solve a problem that a conventional vehicle-mounted monitoring information universal transmission platform system is short of a wireless redundancy link.
