Safe arresting method and system suitable for ship group lockage
The invention discloses a safety arresting method and system suitable for ship group lockage, and the method comprises the steps: building a group lockage fleet locking process safety braking calculation model, detecting the motor rotating speed and torque of an electric push wheel in real time, and calculating the fleet navigational speed in real time through employing an iterative algorithm according to the relevant ship scale parameters and propeller model characteristics of the fleet, thereby achieving the safety arresting of the group lockage fleet. Reckoning the latest braking time before the fleet enters the gate and stops, and gradually reducing the rotating speed of a propulsion motor by adopting a frequency converter rotating speed control mode; if the rotating speed control fails or the navigational speed still exceeds a set value after speed reduction, active arresting systems are arranged on the two sides of a lock surface away from a ship lock working gate safety braking distance, a fleet is actively decelerated and stopped in a friction braking mode, and if the navigational speed still exceeds the set value after the ship is intercepted by the active arresting systems, an anti-collision system arranged at the lower lock head of the ship lock acts; secondary arresting is carried out, and the safety of ship lock equipment and facilities and lockage ships is guaranteed; the ship can pass through the ship lock hub safely and efficiently.
本发明公开一种适用船舶成组过闸安全拦阻方法及系统，包括：建立成组过闸船队进闸过程安全制动计算模型，通过实时检测电动推轮的电机转速和转矩，并根据船队相关船舶尺度参数及螺旋桨模型特性，采用迭代算法实时计算船队航速，推算船队进闸停靠前最晚制动时间，并采用变频器转速控制方式，使推进电机转速逐渐下降；若转速控制失效或减速后航速仍超过设定值，距船闸工作闸门安全制动距离处闸面两侧各设置主动拦阻系统，通过摩擦制动方式使船队主动减速停船，若经过所述主动拦阻系统拦截后航速仍超过设定值，船闸下闸首设置的防撞系统动作，进行二次拦阻，保障船闸设备设施和过闸船舶的安全；通过本发明能够使船舶安全高效的通过船闸枢纽。
