远程通信系统是船舶航行任务接收的重要支持，远程通信质量直接影响船舶航行执行任务，为此在无线网络的支持下，从硬件和软件2个方面，优化设计船舶远程快速通信系统。调整无线网络的拓扑结构，改装船舶通信数据无线收发器和数据处理器，通过电容耦合提高硬件系统的抗干扰性能。在硬件设备的支持下，设置无线网络通信协议，通过通信数据与可用空间的比较，选择合适的通信信道。最终在通信拥塞控制下，实现系统的远程快速通信功能。综合无干扰和有干扰2种环境中的系统测试数据统计结果，得出结论：与传统通信系统相比，设计系统的通信数据丢失量更少、受干扰程度更小，且在通信时延缩短了约2 200 ms，由此证明优化设计的远程通信系统在稳定性和通信速度方面更加具有优势。
Ship remote communication system is an important support for ship navigation task reception. The quality of remote communication directly affects the execution quality of ship navigation task. Therefore, with the support of wireless network, the ship remote fast communication system is optimized from two aspects of hardware and software. Adjust the topology of wireless network, refit the wireless transceiver and data processor of ship communication data, and improve the anti-interference performance of hardware system through capacitive coupling. With the support of hardware equipment, set the wireless network communication protocol, and select the appropriate communication channel by comparing the communication data with the available space. Finally, under the control of communication congestion, the ship remote fast communication function of the system is realized. Based on the statistical results of system test data in non-interference and interference environments, it is concluded that compared with the traditional communication system, the designed system has less communication data loss, less interference, and the communication delay is shortened by about 2 200 ms, which proves that the optimized remote communication system has more advantages in stability and communication speed.
