TD-MS400P-PT Underwater Construction 3D Monitoring System

share

Introduction
TD-MS400P-PT underwater construction 3D monitoring system is a multibeam echo sounder with slanting installation and 360° rotation measurement. It also has the moving measurement function and fixed point sweeping measurement function of the traditional multibeam echo sounders. The system is a software and hardware all-in-one solution product specially designed for typical applications such as dredging, riprap monitoring, erosion protection, bridge pier detection, etc is an ultra-miniature and highly integrated all-in-one multibeam echo sounder, specially developed for small-sized unmanned surface vehicle (USV) and underwater unmanned device survey applications. It fully integrates the surface sound velocity meter, attitude indicator, GPS, etc. Meanwhile, its various interfaces are developed externally, supporting the synchronous work with other devices.

Features
●Large-sweeping-width and high-efficiency measurement: High-precision dual-axis PTZ support for automatic tilt measurement and 360° rotation measurement, effectively improving the efficiency of fixed and mobile measurements. Multi-function support for tilt measurement, mobile measurement and fixed monitoring, simple operation and accurate measurement, 3D real-time display, providing users with a complete solution.
●Multi-scenario engineering application: All-in-one hardware system design and professional PTZ control software to ensure that the system not only can be fixed for underwater 3D monitoring, but also has the moving measurement function for conventional terrain sweeping survey.
●Professional software design: It is an operational software specially designed for underwater 3D construction monitoring. It can display the underwater 3D scenario changes in real time, realize 4D data presentation, and perform accurate construction monitoring.
●Humanized and convenient operation: The hardware and software system is designed in consideration of the operation habits of the on-site construction personnel. It is featured with simple operation and intuitive display, and can be directly put into the engineering application.
