In order to alert the diver, the underwater work management device of the first embodiment sends an alarm and a evacuation instruction directly from the underwater positioning system to the transponder carried by the diver and is incorporated in the transponder. This is to drive the vibration function.
FIG. 1 shows a submarine ship 11 equipped with an underwater positioning system, in which a transducer 12 having a function of emitting an ultrasonic wave and receiving an ultrasonic wave is attached to the bottom of the ship.

  The transducer 12 receives ultrasonic waves from the transponder 14 carried by the diver 13 and detects the coordinate position of the transponder.

  When the transponder 14 receives the trigger signal emitted from the transducer 12, the transponder 14 emits an ultrasonic signal corresponding to the received signal. The transponder 14 has a mechanism for generating an ultrasonic signal for measuring its own position, and has a function of receiving and vibrating an alarm signal which is a specific ultrasonic signal from the transducer 12. The structure 16 is incorporated.

  When the diver 13 carries the transponder 14 equipped with such a vibration mechanism 16 and works underwater, the state is displayed on the management monitor mounted on the diver's ship 11, and the work area is also displayed at the same time. For example, when it is detected that the diver 13 has deviated from the displayed work area, an alarm signal is fired through the transducer 12, and when the fired alarm signal is received by the transponder 14, the alarm signal is displayed. The vibration mechanism 16 is driven to cause the diver 13 to vibrate and vibrate.

  The vibration mode of the vibration mechanism 16 can be generated in various ways, for example, by changing the vibration interval and the vibration start / stop variation, or by a pattern conforming to the Morse code.

When the diver 13 carrying the vibrator 17 with signal receiver and the transponder 14 works underwater, the state is displayed on the management monitor mounted on the diver's ship 11, and the work area is also displayed at the same time. For example, when it is detected that the diver 13 has deviated from the displayed work area, an alarm signal is emitted through the transducer 12, and the emitted alarm signal is received by the vibrator 17 with a signal receiver. Then, the vibration is driven based on the alarm signal to cause the diver 13 to vibrate by causing vibration.
This type of vibration can be generated in various ways, for example, by changing the vibration interval and the vibration start / stop variation, or by a pattern that conforms to the Morse code. The alarm signal can know what the alarm signal is, and it can be understood that the alarm signal has deviated from the work area or is an evacuation instruction.

In order to alert the diver, the underwater work management device according to the third embodiment is to directly flash an illuminant or turn on a light emitter from the underwater positioning system. A light emitter (LED) is incorporated in the frame frame, and a warning signal and a retract instruction signal are received from a ship with a signal receiver separately carried, and the light emitter is caused to emit light to alert a diver.
