为提升船舶航行路径的经济性与安全性,提出改进神经网络的船舶航行路径规划方法。采用改进神经网络方法求解所建立船舶航行路径规划模型,选取修正线性单元ReLU函数替代原激活函数,选取梯度下降法更新神经网络权重,利用均方根反向传播算法优化神经网络,输出船舶航行路径规划结果。利用船舶航行路径规划结果实施碰撞检测,避免船舶航行路径出现碰撞。实验结果表明,该方法可以有效规划船舶航行路径,规划长度符合预期,未发生碰撞情况,满足船舶航行的经济性以及安全性需求。
In order to improve the economy and safety of ship navigation path, a ship navigation path planning method based on improved neural network is proposed. The improved neural network method is used to solve the established ship navigation path planning model, the modified linear unit relu function is selected to replace the original activation function, the gradient descent method is selected to update the neural network weight, the root mean square back propagation algorithm is used to optimize the neural network, and the ship navigation path planning results are output. Collision detection is carried out by using the results of ship navigation path planning to avoid collision of ship navigation path. The experimental results show that this method can effectively plan the ship's navigation path, and the planned length of the ship's navigation path meets the expected requirements, without collision, and meets the economic and safety requirements of the ship's navigation.
