Design And Research Of Ship Movement State Monitoring And Analysis System

Ship movement state monitoring and analysis system is one important part of integrated bridge system, it displays information from separated sensors and different navigation equipments on one platform, which help ship drivers and managers know about the states of navigation and manipulate the ship. Trailing suction dredger which has ability of self-navigation and dredging during the navigation is one of large-scale project vessel. Trailing suction dredger dredges up the sea-route with the drag generated by navigation and the harrow tooth's action on the riverbed. In this process, either navigation or dredging up has effect on each other, so the monitoring and analysis of navigation and dredging up states are important to ensure the navigation security and improve the efficiency of project. The movement state monitoring and analysis system is researched in this paper. And the emphasis of the research is navigation state and dredging state monitoring.Firstly, the equipments of trailing suction dredger and dredging process is analyses in this paper. And then the basic function of system and net structure are designed. Due to the large information and complex collection methods of system, it designs an effect data collection interface.Secondly, the paper analysis the resource of navigation states information monitored by system and designs the navigation states alarm. It parses the GPS data format and researches the convert modal between different coordinates. An effective coordinate convert method is chose with the GPS's application in trailing suction dredger.Thirdly,in allusion to some problems in the dredging process of trailing suction dredger,3D dredging process states monitoring is designed in paper. This method which is integrated with GIS, computer graphic and dredging process establishes regular grid riverbed modal with contour traced and the movement modal of equipments. This 3D monitoring is realized by using OpenGL library.At last, according to system's requirement of large data transferring and real-time, this paper designs an effective communication between client and server. The functions of clients are also realized in this chapter. This system is developed in the platform of VC6.0. Practical operation effect shows that this system is valuable in actual project.
