Description

  The present invention relates to a diving management system for managing underwater work by divers such as abandoning stone leveling work on the seabed and the like, in particular, the ascent of divers after the work is completed.

After the underwater work on the sea floor, divers are obliged to ascend while stopping for a predetermined time at a predetermined water depth based on the high-pressure work safety and health regulations to prevent decompression sickness.
However, conventionally, since the diving depth and diving time of divers were managed by voice communication with a liaison officer on a diver's ship, they were not immediately and objectively performed. In other words, the action cannot be immediately grasped on the diver's ship unless there is contact from the diver, such as when the diver temporarily moves to a place deeper than the planned depth. Also, in the ascent management (decompression management), it is left to the diver's self-judgment, and the record of the underwater work can be grasped only after the work is completed, so it is different from the underwater work plan in which the actual underwater work time is planned in advance. In this case, there was a problem that the diver could not be raised immediately according to the ascent plan according to the actual work.

  Further, Patent Document 1 includes an indicator lamp installed on a diver's ship so as to be visible from the periphery, and a plurality of the indicator lamps are provided in a tandem arrangement in accordance with the ascent stop depth of the diver. A display device is disclosed.

  In the invention related to the ascent depth display device of Patent Document 1 described above, the ascent status of the diver can be confirmed in real time from around the diver's ship, but the diver's diving depth and diving time are always displayed on the diver's ship. In particular, it does not attempt to ascend a diver according to an appropriate ascent plan.

  The present invention has been made in view of the above points, and can always ascertain the diving depth and diving time of a diver on a diver's ship, and can safely ascend the diver along an appropriate ascent plan. The purpose is to provide a diving management system.

As a means for solving the above-mentioned problems, the present invention provides a diving management system for managing a diving plan from a diving start of a diver to ascending through an underwater work, A depth measuring means held by a diver, a warning means held by a diver and allowing a diver to recognize an instruction from the diver's ship, a diving depth and a diving time from the depth measuring means provided on the diver's ship. And a management means for activating the warning means based on the ascent plan entered in advance, and the management means re-executes the ascent plan when the actual underwater work time of the diver is different from the underwater work plan. The warning means is operated based on a result of the calculation, and the warning means is composed of an underwater warning light, and the underwater warning light is provided with a plurality of indicator lights with different indication colors arranged in an appropriate manner. In line with the plan According to the signal from the control means, the diver is instructed to ascend by the blinking state of each indicator light of the underwater warning light, and the diver is in the ascending position by any lighting state of each indicator light. It is characterized by instructing standby .
In the invention of claim 1, based on the measurement result from the depth measurement means, the management means provided on the diving ship always keeps track of the diving depth and diving time of the diver, and the diving acquired by the management means The warning means is activated based on the diving depth and diving time of the craftsman and the ascent plan previously input, and the diver can ascend according to the proper ascent plan by recognizing it.
Also, if the actual underwater work time differs from the underwater work plan, the management means recalculates the ascent plan when the diver ascends, and provides warning means based on the ascent plan according to the actual underwater work. Once activated, the diver can recognize it and ascend according to the appropriate ascent plan.
In addition, according to the first aspect of the present invention, an appropriate ascent plan is verbally instructed from the contact person on the diver's ship to the diver via the underwater communication means, and at the same time the warning means that the diver holds the proper ascent plan. Since the diver can be instructed by operating the, the reliability is greatly improved.
Further, in order to make the diver ascend based on the appropriate ascent plan, first, for example, a red light of the underwater warning lamps held by the diver starts flashing in response to a signal from the management means. The diver starts to ascend by visually checking the flashing state of the red light. During the ascent, the red light keeps blinking, and when the diver reaches the first ascent stop position, the red light switches from the blinking state to the lit state, so the diver visually recognizes the lit state of the red light. Stop ascending. Thereafter, when a predetermined time elapses at the first levitation stop position, the red lamp is turned off, and for example, a yellow lamp located next to the red lamp starts blinking. The diver visually checks the blinking state of the yellow light and starts ascending from the first ascent position. During the ascent, the yellow light keeps blinking. When the diver reaches the second ascent position, the yellow light switches from blinking to lit, and only the yellow light comes on. Visually checks the lighting state of the yellow light and stops ascent and waits for a predetermined time at the second ascent position. Thereafter, if there is a next levitation stop position, the above-described operation is repeated.
Thus, a diver can ascend safely by visually recognizing an underwater warning light that operates in accordance with an appropriate ascent plan.

For example, three marking lamps 4a, 4b, and 4c are provided, and are composed of a red lamp 4a, a yellow lamp 4b, and a green lamp 4c from the upper side.
The indicator lights 4a, 4b, and 4c of the onboard warning light 4 blink or light up in a timely manner in the same manner as the indicator lights 3a, 3b, and 3c of the underwater warning light 3, based on the signal from the management means 5. Will be described in detail later.

The management means 5 is composed of, for example, a personal computer, and calculates the diving depth and diving time of the diver based on a signal from the water pressure sensor 2 held by the diver. The diving depth of the diver is displayed on the monitor (not shown) of the personal computer of the management means 5 as time passes. The management means 5 is inputted in advance with a diving plan from the start of diving by the diver to ascending through the underwater work, and the diving plan as shown by a solid line in FIG. 3 is displayed in advance on the monitor. The actual diving trajectory is displayed in real time by changing the line type so as to overlap it, for example, with a dotted line or the like. In addition, the ascent plan of the diving plan is the ascent plan for the underwater work, in accordance with the high-pressure work safety and hygiene rules, recorded in the management means 5 with respect to the maximum depth and the elapsed time for each underwater work on that day.

The indicator lights 3a, 3b, and 3c are actuated (blink or turn on as appropriate) and are then surfaced (detailed later). The onboard warning light 4 operates in the same manner as the underwater warning light 3, and information similar to the information given to the diver is given to the onboard contact person.
Further, when the diver is diving and the actual underwater work time of the diver is different from the underwater work plan, the management means 5 recalculates the first ascent plan entered, and based on the result, The warning light 3 and the onboard warning light 4 are actuated to raise the diver according to an appropriate ascent plan.

Next, the operation of the diving management system 1 according to the embodiment of the present invention will be described based on FIGS. 4 and 5 with reference to FIGS.
As shown in FIG. 4, first, in step S1, the diving plan from the start of diving by the diver to ascending through the underwater work as shown in FIG. 3 is input to the management means 5, and the diving is input to the monitor. The plan is displayed as a solid line, for example.
Next, in step S2, diving of the diver is started.
Next, in step S3, the diving depth is calculated by the management means 5 based on the measurement result from the water pressure sensor 2, and the measurement of the elapsed time is started when the water depth (diving depth) reaches 3 m.
Next, in step S4, the management means 5 sequentially records the diving depth with the elapsed time, and displays the diving trajectory in real time on the monitor (dotted line in FIG. 3).

Next, in step S5, it is determined by the diver whether or not the underwater work has been completed. As a result, when it is determined that the underwater work has been completed, the process proceeds to step S6, and when it is determined that the underwater work has not been completed, the process proceeds to step S7.
As shown in FIG. 5, the determination of the end of the underwater work in step S5 is performed in step S5-1. L = (H + Z) / 2−D is calculated as the depth H of the hour and the first levitation stop position (depth) Z according to the levitation plan. Subsequently, in step S5-2, it is determined whether or not L> 0 is satisfied. If L> 0 is satisfied, the process proceeds to step S6 in FIG. On the other hand, if L> 0 is not satisfied, the process proceeds to step S7 in FIG.

Next, in step S7, it is determined whether or not the scheduled work time has been exceeded. If the scheduled work time has not been exceeded, the process returns to step S5 again after the predetermined time has elapsed, and the determination of the end of the underwater work is performed. . On the other hand, if it is determined in step S7 that the scheduled work time has exceeded, the process proceeds to step S8. In step S8, the red lights 3a and 4a among the indicator lights of the underwater warning light 3 and the onboard warning light 4 are displayed. Flashes and a warning sound is emitted on the diver's ship. This informs the diver that the underwater work has exceeded the scheduled time. Thereafter, after a predetermined time elapses, the process returns to step S5 to determine whether or not the underwater work is finished.
Next, in step S6, it is determined whether or not the actual underwater work time has been performed within a predetermined allowable time with respect to the underwater work plan input in advance to the management means 5, and the actual underwater work time is underwater. When the work plan is performed within a predetermined allowable time, the process proceeds to step S11 to raise the diver based on the initial ascent plan. On the other hand, when the actual underwater work time deviates from the allowable time for the underwater work plan time and is significantly shortened or greatly exceeded, the process proceeds to step S10, and the ascent plan is recalculated based on the actual underwater work time. The Thereafter, the process proceeds to step S11 in order to ascend the diver based on the recalculated ascent plan.

Next, steps S11 to S16 are a flow for safely ascending the diver based on an appropriate ascent plan.
That is, in step S11, the red light 3a, 4a of each of the underwater warning light 3 and the onboard warning light 4 starts to flash by a signal from the management means 5, and a warning sound is emitted on the diver's ship. Then, the diver visually recognizes the blinking state of the red light 3a of the underwater warning light 3 and starts ascending from the current position. During the ascent, the red lights 3a and 4a of the underwater warning light 3 and the onboard warning light 4 are kept blinking, and the warning sound is also maintained. Subsequently, in step S12, when the diver reaches the first ascent position, the red lights 3a and 4a of the underwater warning light 3 and the onboard warning light 4 are switched from the blinking state to the lit state. By visually observing the lighting state of the red light 3a, the ascent is stopped and waits at the first ascending position. At this time, the warning sound is stopped on the diver's ship. Subsequently, in step S13, when the waiting time at the first ascending position is measured and the waiting time ends, the process proceeds to step S14. In step S14, it is determined whether or not there is a next levitation stop position. As a result, if it is determined that there is no next levitation stop position, the process proceeds to step S16, where all the indicator lights of the underwater warning light 3 and the onboard warning light 4 (the red light 3a in this embodiment). 4a, yellow lights 3b, 4b and green lights 3c, 4c) are in a blinking state for 5 seconds, and a warning sound sounds on the diver's ship, instructing the diver to ascend to the surface of the water.

  On the other hand, if it is determined in step S14 that the next levitation stop position is present, the process proceeds to step 15, and in step S15, the red lights 3a and 4a of the underwater warning light 3 and the onboard warning light 4 are turned off. In step S11, the yellow lights 3b and 4b of the underwater warning light 3 and the onboard warning light 4 start to flash, and a warning sound is emitted on the diver's ship. Then, the diver visually recognizes the blinking state of the yellow light 3b of the underwater warning light 3 and starts ascending from the first ascent position, and during the ascent, the yellow light of each of the underwater warning light 3 and the onboard warning light 4 is displayed. In 3b and 4b, the blinking state is maintained, and the warning sound is also maintained. Subsequently, in step S12, when the diver reaches the second ascent position, the yellow lights 3b and 4b of the underwater warning light 3 and the onboard warning light 4 are switched from the blinking state to the lit state. The lighting state of the yellow light 3b of the lamp 3 is visually confirmed, the ascent is stopped, and a standby is performed at the second ascending position. At this time, the warning sound is stopped on the diver's ship. Subsequently, in step S13, the waiting time at the second ascent position is measured, and when the waiting time ends, the process proceeds to step S14. In step S14, it is determined whether or not there is a next levitation stop position.

  Further, if it is determined in step S14 that the next levitation stop position is present, the process proceeds to step 15 again, and the yellow lights 3b and 4b of the underwater warning light 3 and the onboard warning light 4 are turned off in step S15. In step S11, the green lights 3c and 4c of the underwater warning light 3 and the onboard warning light 4 start to flash, and a warning sound is emitted on the diver's ship. Then, the diver visually recognizes the blinking state of the green light 3c of the underwater warning light 3 and starts to ascend from the second ascent position. During the ascent, the green lights of the underwater warning light 3 and the onboard warning light 4 respectively. In 3c and 4c, the blinking state is maintained, and the warning sound is also maintained. Subsequently, in step S12, when the diver reaches the third ascent position, the green lights 3c and 4c of the underwater warning light 3 and the onboard warning light 4 are switched from the blinking state to the lit state. The lighting state of the green light 3c of the lamp 3 is visually confirmed, the ascent is stopped, and a standby is performed at the third ascending position. At this time, the warning sound is stopped on the diver's ship. Subsequently, in step S13, when the waiting time at the third ascending position is measured and the waiting time ends, the process proceeds to step S14. In step S14, the presence / absence of the next levitation stop position is determined, and the process proceeds to step S15 or step S16 based on the result.
