Abstract-To study the application of wireless sensor in the ship dynamic positioning system, the distributed fusion function model and structure model of wireless sensor network were set up. Using the DJC model-based SVM prediction algorithm, the quadratic optimal performance index in ship dynamic positioning MPC control was solved and the optimal control thrust was obtained. According to the classic cluster routing protocol, a data fusion structure based on residual energy and dormancy scheduling mechanism was proposed. The results showed that the proposed routing protocol based on the residual energy and sleep scheduling mechanism data fusion structure was superior to the Leach protocol. It improved the real-time performance of data transmission. Thus, the network data fusion structure achieves the goal of energy balance. The energy consumption is reduced to a certain extent and the design is reasonable.Keywords-wireless sensor, ship navigation, model, system IntroductionThe wireless sensor network is used in the ship positioning system. Ship position information, heading information and environmental information are monitored. The system requires each sensor node to transfer the measured information to the control system, so that the controller can calculate, analyze and process information. Here, the controller is not realized by the traditional computer, but by the convergence node of the wireless sensor network. It has good flexibility and reliability. In the ship positioning control system, the control object mainly includes three aspects: position control, heading control and track control. Combined with data fusion model of ship dynamic positioning system, the application of decision control method based on sink node fusion structure in optimal control thrust prediction is studied. Based on the cluster data fusion structure, the network transmission protocol of the ship dynamic positioning system is designed. 98
