摘要
针对我国部分内河流域存在4G信号覆盖盲区,尤其位于山区航道的4G信号覆盖盲区,导致内河船舶通信应用受到限制、关键时刻可能没有信号等问题,在4G信号覆盖区内以4G通信为主,通过4G通信与岸基进行信息的双向传输;在4G信号盲区内,切换成北斗短报文通信,以保证内河船舶航行过程中通信的连续性。经过多次测试验证,该技术可实现内河船舶在航行过程中与岸基的无间断通信。
There are blind areas of 4G signal coverage in some inland river basins in China,especially in mountainous waterways,which leads to the limitation of communication of inland river vessels and the possibility of no signal at critical moments.An intelligent terminal ship-to-shore communication technology based on Beidou short message and 4G was proposed.In the 4G signal coverage area,4G communication was mainly used to transmit information in both directions through 4G communication and shore-based;in the 4G signal blind zone,it is switched to Beidou short message communication to ensure the continuity of communication during the navigation of inland river vessels.After several tests,the technology can realize uninterrupted communication between inland vessels and shore base during navigation.
