摘　　要：考虑封闭水域船舶的运动特征和水上交通监管要求,运用广域物联网技术设计新型船舶识别系统,提出基于封闭水域船舶通航密度和船舶航速的数据管理方法,通过分析通信信道传输能力制定数据传输协议与频率。采用基于长距离无线广域网(LoRaWAN)协议的网关布局方法,并根据系统的网络规模和网关传输能力建立数据上下行机制。仿真与实验表明,该系统布设方便,数据传输可靠,能够满足封闭水域船舶自动识别的需求,可广泛应用于封闭水域的船舶辅助导航与安全监管。A new type of ship automatic identification system was designed and implemented based on wide-area internet of things for the characteristics and regulatory requirements of ships in enclosed waters.The data transmission protocol based on communication channel transmission capability,the data management method based on the navigation density of ships in enclosed waters and the ship speed,the gateway layout method based on LoRaWAN network protocol,and the data uplink and downlink mechanism based on system scale and gateway transmission capacity were designed.Simulation and experiments showed that the system is easy to deploy and reliable in data transmission.It can meet the needs of automatic identification of ships in enclosed waters,and can be widely used in ship-assisted navigation and safety supervision in enclosed waters.
