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.

[0002] In engineering construction and other fields, such as immersed tube tunnel construction and offshore ship platforms, it is necessary to accurately measure the orientation and three-dimensional posture of large moving objects in order to facilitate construction docking and ensure engineering safety, especially for underwater mobile construction projects. , not only requires a high degree of safety, but also the entire construction process is below the water surface, the construction area is far from the shore, and the construction period is relatively long, especially if the water body where the project is located has high turbidity, even if an underwater camera is installed, the construction process cannot be seen clearly , which will bring higher difficulty to the construction, prone to major accidents such as collisions

The existing traditional methods are generally measured by means of divers' exploration and measurement data reporting, which is not only inefficient but also not intuitive and accurate enough. In this case, it is necessary to provide a centimeter-level accuracy that can work independently for a long time around the clock. , The information integration system that can collect the azimuth and inclination data of the mobile platform at multiple points at the same time and wireless long-distance transmission, and display the real-time 3D dynamic model will provide efficient, intuitive and accurate engineering reference for the construction process
