Research And Development Of Intelligent Navigation Aid System For Inland Waterway

In inland navigation,the traditional navigation aids can only provide simple visual navigation,and there are serious phenomenas of loss or drift.They can not locate the fault navigation aids in time,and can only be maintained by manual cruise.Navigation environment informations,such as wind speed,wind direction and GPS navigation mark positioning,are mainly collected by manual,which has a large workload and potential safety hazards.In the course of ship navigation,collision and yaw accidents occur from time to time due to the lack of safety assistance mechanism.In order to solve the above problems,an intelligent navigation mark system is developed in this paper.Firstly,by analyzing the research status at home and abroad and the drawbacks of the current navigation mark system,the research approach of intelligent navigation mark monitoring system and equipment is clarified,and the hardware and related software of each node of intelligent navigation mark monitoring equipment are determined.The main processor of navigation mark node is ARM host,ZigBee is node communicator,GPS module is used for navigating mark positioning,wind speed and direction sensor and network data receiving and receiving module are external devices.The whole intelligent navigation mark device adopts embedded Linux system architecture.Secondly,the main processor,interface circuit and related peripheral modules used in navigation aids are elaborated in detail.The ARM host,Linux system and C language compiler are discussed.Then,combined with the working status of the beacon and the analysis of ZigBee networking,the communication program between each beacon node,the data receiving and receiving program of ARM host client and the data receiving and storing program of server side are designed and implemented.The collision node checking method and collision avoidance function based on Bayesian sewing are proposed,and the trajectory planning algorithm is realized.In this paper,the method of channel trajectory prediction and anti-collision behavior is studied with the program of intelligent navigation mark system.Finally,the navigation mark model is developed,and the position information and environmental parameters of the navigation mark are obtained successfully through relevant experiments in the river,which realizes the effective supervision of the navigation mark system.Experiments prove that the intelligent navigation mark system developed in this papercan monitor the working status and position of the navigation mark remotely through the back-end server,and manage the navigation mark intelligently,which reduces the cost of manual maintenance and ensures the safety of the waterway ship.
