A positioning and navigation aid system for group lockage of tugboat traction ships comprises a laser radar and a millimeter wave radar which are used for collecting posture and position data of entering and exiting of the group ships; the laser radar and the millimeter-wave radar are connected with the shore-based server, and the shore-based server is used for receiving the laser radar point cloud and message data of the millimeter-wave radar, processing the laser radar point cloud in real time, obtaining information such as the position, heading angle and navigational speed of the grouped ships in the lock chamber, and sending the information to the shore-based server. And meanwhile, the millimeter wave radar message is analyzed, and the information is sent to a ship-end server through a local area network. And the ship end server is used for receiving data of the laser radar, the inertial navigation system and the differential Beidou base station, receiving laser radar and millimeter wave radar data sent by the shore end server through a local area network, and generating accurate positioning information of the electric tug through multi-source data fusion. The ship is dragged to enter the lock in a grouped mode, the ship entering time can be shortened, and the ship lock operation efficiency is improved.

    一种拖轮牵引船舶成组过闸的定位及助航系统,该系统包括:激光雷达、毫米波雷达,用于采集成组船舶进厢和出厢的姿态和位置数据;激光雷达、毫米波雷达均连接岸基服务器,岸基服务器用于接收所述激光雷达点云、以及毫米波雷达的报文数据,并对激光雷达点云实时处理,获取成组船舶在闸室内的位置、艏向角、航速等信息,同时对毫米波雷达报文解析并通过局域网将上述信息发送给船端服务器。船端服务器用于接收激光雷达、惯导系统以及差分北斗基站的数据,并通过局域网接收岸端服务器发送的激光雷达与毫米波雷达数据,通过多源数据融合,生成电动拖轮的精确定位信息。本发明实行牵引船舶成组方式进闸,可缩短船舶进闸时间,提高船闸运行效率。
