双控制河段船舶通行指挥系统设计与实现

Design and implementation of ship traffic control system in double control waterway

针对双控制河段缺乏有效船舶通行指挥方法的现状,在考虑工程实际因素的基础上,应用网络、通信、计算机、人工智能等理论和技术手段,设计了一种基于智能控制算法的双控制河段船舶通行指挥系统。该系统以船载自动识别系统(automatic identification system,AIS)作为主要信息源,采用改进卡尔曼滤波方法实现对船舶位置的实时跟踪预测,以船舶到达和通过控制河段的行程时间为依据,并结合船舶操纵特性,制定了一套船舶安全通行排序规则和指挥方法。泸州永川航段双控制河段的实地应用结果表明,文章提出的双控制河段船舶通行指挥系统可行性较好,能够降低信号员工作强度,并能提高控制河段通航服务水平和通行指挥效率。

Aiming at the problem of lacking effective access control method in double control waterway, doublecontrol waterway technology, database technology, artificial intelligence technology were designed with the consider-ation of practical facts. The system takes AIS as a main information source, and uses the improved Kalman filteringmethod to realize the real-time tracking and prediction of the ship′s position, on the basis of the time of ship arrivaland through the reach, combines the control characteristics of the ship, finally makes the ship′s safe traffic orderrules and command method. The application results of Luzhou Yongchuan section double control waterway showsthat the proposed system has practical feasibility, reduces the work intensity of the workers, and improves the navi-gation service level and traffic control efficiency.
