【摘要】：船舶动力定位系统是一种船舶位置与动力控制系统,能够根据海浪、海风等外界干扰条件,协调船舶的推进系统、导航系统,自动修正船舶的当前位置,保持船舶姿态和航向的稳定,确保船舶能够按照正确的航线行驶。船舶动力定位系统的关键在于正确估计船舶的当前位置,在这种情况下,传统使用的GPS、北斗等卫星定位系统精度较低,难以实现船舶灵活、快速、高精度的调整与控制动作。本文提出一种基于无线传感器网络WSN的船舶动力定位控制模型,利用传感器网络测量外界风力、风向,结合当前船舶的行驶航向,利用数学模型估计船舶的偏移量,进而进行智能的控制。通过仿真实验表明,相比于传统方法,本文提出的方法能够以较低的实现代价,实现较高的动力定位精度,具有较高的实用价值。
[Abstract]:Ship dynamic positioning system is a kind of ship position and power control system, which can coordinate the propulsion system, navigation system and automatically correct the current position of the ship according to the external disturbance conditions such as wave, sea breeze and so on. The key of ship dynamic positioning system is to correctly estimate the current position of the ship. In this case, the traditional use of GPS. Beidou satellite positioning system is difficult to achieve flexible, fast and high precision adjustment and control of ship. A ship dynamic positioning control model based on wireless sensor network (WSN) is proposed in this paper. The sensor network is used to measure the external wind force and wind direction, combined with the current ship's heading, and the mathematical model is used to estimate the deviation of the ship, and then the intelligent control is carried out. Compared with the traditional method, the method proposed in this paper can achieve higher dynamic positioning accuracy at a lower cost and has a higher practical value.
