Problems solved by technology

However, because the general acoustic equipment is fixed on the ship, the use is not flexible enough, and the requirements for the water depth are high. At the same time, the acoustic positioning is also easily disturbed by environmental noise (such as the multi-path effect of the aquatic channel), reflection and obstacles, etc., the scope of application and flexibility is greatly limited

Abstract

The invention relates to an underwater intelligent umbilical cable positioning system and a method for positioning a diver. The positioning system is mainly composed of a water surface terminal, a cable, an umbilical cord and a plurality of underwater nodes installed on the umbilical cord. Each underwater node comprises an inertia measurement unit used for detecting and processing the triaxial attitude angle and acceleration of the underwater node in parallel, a depth meter used for detecting the water depth of the current position of the underwater node, and a data calculation and transmission module used for processing data of the inertial measurement unit and the depth meter and transmitting the data to the water surface part. The water surface terminal comprises a calculation unit, a coordinate receiver used for obtaining GPS or Beidou coordinates of each underwater node, and a power supply module used for supplying power to the underwater nodes, the calculation unit and the coordinate receiver.

Description

technical field [0001] The invention relates to an underwater intelligent umbilical cable positioning system and a method for positioning divers. Background technique [0002] Such as figure 1 As shown, when divers use tube-fed diving equipment for underwater operations, they use umbilical cords to connect to the water surface. The role of the umbilical cord is to provide breathing gas, communication and other functions from the water surface. As we all know, divers have higher risks when working underwater, and the most important point is that they cannot accurately grasp the exact position of divers underwater. [0003] At present, the underwater positioning of divers is mainly performed by acoustic means, such as ultra-short baselines. However, because the general acoustic equipment is fixed on the ship, the use is not flexible enough, and the requirements for the water depth are high. At the same time, the acoustic positioning is also easily disturbed by environmental ...
