Description

  The present invention relates to a diver position management system for managing the diving depth and plane position of a diver.

  When building a revetment foundation for harbors and landfills, throw rubble into the construction site, level the top edge of the rubble, level it to the planned height, and place blocks, caissons, etc. on it. install. Conventionally, when leveling rubble thrown into the water or installing blocks, caissons, etc., diving work by divers has been required.

  In diving work, it is necessary to observe the diving time and the ascent time according to the diving depth in accordance with the safety and health regulations in order to prevent high-pressure problems such as decompression sickness. However, management of diving depth is often left to the diver himself, and there have been cases where decompression sickness has developed due to misunderstanding or misunderstanding of the diver. In addition, when a plurality of diving operations are performed in one day, since the first diving is affected by the concentration of nitrogen gas taken into the body, the workable time is shortened after the second diving compared to the first diving. Even in this case, there were cases in which decompression sickness developed due to misunderstanding and misunderstanding of divers.

  In order to solve such a problem, for example, in Patent Document 1, a diving person is equipped with a water depth sensor, and based on the diving information of the diver obtained from the water depth sensor, the diving time according to the diving depth, A diving management system is disclosed in which the ascent method, the ascent time, and the ascent time at the second and subsequent dives are calculated and necessary information is notified to the diver based on the calculation result.

  On the other hand, when installing a block or the like using a hoist ship, there is a risk that an accident or a disaster may occur because the diver and the block for installation are complicated. In the past, the contact person confirmed the position of the diver based on the diver's bubbles, but there were cases where the work was dangerous due to misunderstanding or misunderstanding of the contact person.

  In order to solve such a problem, for example, Non-Patent Document 1 discloses a position of a hoist vessel / crane-mounted carrier and a diver using a device that can be simply equipped with an underwater transponder and GPS. A block installation construction management system that monitors the position and the position of a suspended load such as a block in real time is disclosed.
