Monitoring and display system for position and three-dimensional attitude of floating and semi-submersible type mobile platform

Abstract

A monitoring and display system for a position and a three-dimensional attitude of a floating and semi-submersible type mobile platform comprises an RTK (real time kinematic) DGPS (differential global position system) positioning module which is used for obtaining positioning data of the mobile platform; a bidirectional gravity type inclinometer module which is used for obtaining longitudinal and transverse inclination data of the mobile platform; a wireless transmission module which is used for transmitting the positioning data and the inclination data to a synchronous collection and processing module; the synchronous collection and processing module which is used for collecting the positioning data and the inclination data synchronously and converting the positioning data into a presupposed type coordinate system; and a real-time three-dimensional animation and information display module which is used for dynamically displaying the position and the three-dimensional attitude of the mobile platform in real time in a three-dimensional simulation mode. By means of the GPS (global position system) and the animated simulation, the monitoring and display system for the position and the three-dimensional attitude of a floating and semi-submersible type mobile platform displays dynamically the position and attitude information of the mobile platform in real time, and has the advantages of being intuitional, efficient and highly-accurate, thereby largely improving the safety in construction and engineering efficiency, and having a high automaticity, an accurate measurement during work process and a wide prospect.
