Abstract


With the development of battlefield information, in order to meet different business needs application of various heterogeneous wireless communication network, these network channels are independent of each other, there are difficult to quickly back up each other's shortcomings. At the same time, with the battlefield variety of command and control and situational information, the existing wireless narrowband channel in the information exchange process is difficult to meet the need of reliable information transmission. In response to these problems, the paper proposes a mobile field command and information transmission platform overall technology program, mainly used to solve the the battlefield multiple wireless channel integrated access to multiple wireless channel back up each other, the channel automatically and quickly switch priority, reliable wireless network information transmission and other issues. System design involves two key technologies: First, the wireless channel preferred channel auto-switching technology. Based on the technology, design and implementation of wireless channel controller, wireless channel controller integrated access TBR-121C FM radio, the TCR-154A shortwave radio (radio built-in or external modem), CDMA channel and Beidou No. 1 user machine and other channel to achieve the heterogeneous channel network communication, and provide a variety of wireless data transmission means for the user terminal. According to the CDMA 1X the TBR-121C, the TCR-154A, the order of the Compass automatically select the communication channel, and four data transfer backup for each other. The second is the reliable information transmission technology wireless narrowband environment. The article refers to the U.S. military-related mobile communication system solutions, traditional the commercial TCP protocol applied to the wireless link certain defects, the the UDP application layer connectionless reliable transport protocol solutions to ensure reliable information transmission in a wireless network environment, and with reference to the OSI seven-layer protocol model, the 47001/IP communication protocol stack model. On this basis, the application layer, the detailed design and implementation of reliable transport protocol connectionless. The paper first describes the status quo of the issues raised by the background and development of related technologies, and mobile field command and information transmission platform architecture of the overall design. And, respectively, to focus on wireless channels preferred system implementation and automatic switching technology and wireless narrowband environment reliable transmission technology. On this basis, describing the system implementation and application. Finally, the summary of this paper work, and look forward to the next work.
