摘　　要：为了准确控制大型船舶安全靠泊,分析了大型船舶特点及其靠泊过程,建立了大型船舶辅助靠泊仪数学模型,设计了大型船舶靠泊仪及其软件终端显示系统。采用两点定位差分全球定位技术(DGPS)、船舶自动识别技术(AIS)和无线网路通信技术(WiFi)完成靠泊仪的设计和数据的传输,结合大型船舶辅助靠泊仪数学模型,计算船舶靠泊时船首和船尾相对码头的距离、速度、船首向与船舶转向率等船舶移动数据,并将这些数据通过WiFi发送到软件终端,为引航员引导船舶安全靠离港提供参考信息。测试结果表明:大型船舶靠泊仪的水平定位精度可达60cm,速度精度可达到5cm·s-1,数据刷新频率为5次·s-1。In order to accurately control the safe berthing of large ship, the characteristics and berthing process of large ship were analyzed, the mathematic model of its auxiliary berthing instrument was established, and the berthing instrument and its display system of software terminal were designed. The two-point position differential global positioning system （DGPS） technology, automatic identification system（AIS） technology and wireless fidelity（WiFi） technology were used to complete the design of berthing instrument and the data transmission, and the berthing mobile data including the relative distances and speeds between bow, stem and wharf, the heading and the steering rate were calculated, which were sent via WiFi to the software terminal for the pilots to guide the safe berthing and unberthing of ship. Test result shows that the berthing instrument＇s horizontal positioning accuracy is 60 cm, the speed precision is 5 cm· s 1 and the data refreshing frequency is 5 times· s-1. 1 tab, 12 figs, 11 refs.
