Abstract

The invention relates to a measuring and positioning system of an underwater evener, which comprises an evening boat measuring and positioning system, an evener measuring and positioning system and a microprocessing unit. The invention adopts a positioning mode that an evening boat and an evener are respectively independent, accurately determines the plane position, elevation and horizontal attitude when the underwater evener works and the actual elevation of a foundation bed surface in acceptance through the equipment of a GPS (global positioning system), a tilted sensor, a position sensor, a depth sounder and the like, simultaneously realizes the position and attitude positioning of the evening boat, and realizes the functions of design and management of a working zone, data acquisition of the equipment, real-time calculation, real-time display, early alarm and alarm for limit overrun, data storage, data playback and the like through the microprocessing unit.

Description

technical field [0001] The invention relates to an underwater bed leveling device, in particular to a measurement and positioning system for an underwater bed leveling ship. Background technique [0002] At present, when carrying out deep-water foundation bed leveling operation, use leveling ship and deep-water leveling machine to work together. When carrying out underwater operations, it is necessary to measure and position the leveling boat and leveling machine. The traditional measurement and positioning method is to use the combination of manual observation on the water and underwater manual operation of divers to measure and position the leveling ship and leveling machine. However, due to the strong influence of wind and wave factors, the number of operating days is reduced, and safety production is threatened; at the same time, due to artificial underwater operations, limited by water depth pressure, manual operations are difficult, the effective operation time of divi...
