摘要
针对巨型总段对接过程中船台小车数量多,不易协同控制,严重依赖人工操作的问题,提出了冗余自由度船台小车集群的协调控制技术。首先通过在船段上布置靶标点,利用全站仪测量获取船段当前的位姿,然后用运动逆解算法将对接船段的运动分解成基本的旋转运动和平移运动,进而得到小车集群相关移动量的数据,并且将这些数据从集成软件发送到控制器中,从而实现小车集群协调控制。最后使用搭建好的实验平台展开协调控制的实验,实验结果证明该控制方案具有自动化程度高、对接效率高等优点。
In order to solve the problem thatnumbersof ship trolleys in the matching process of the giant general section are not easy to control and are operated heavily on manual operation,a coordinated control technology for excessive degrees of freedom of ship trolleys is proposed.Firstly,by arranging target points on the ship segment,using the total station measurement to obtain the current pose of the ship segment,and then using the inverse solution algorithm to decompose the motion of the docking ship segment into basic rotary and translational movements,the relevant movements of the trolley will be obtained.These data will be sent from the integrated software to controller and then coordinated control will be realized.Finally,experimental platform is used to carry out the coordinated control experiment.The experimental results prove that the control scheme has the advantages of high level of automation and high matching efficiency.
