Description

  The present invention relates to an underwater work support method and system, and more particularly to an underwater work support method and system capable of improving the safety and workability of underwater work.

  A diving computer that manages various diving information (no decompression diving time, water depth, water temperature, number of diving, etc.) related to the safety of divers is known (for example, Patent Document 1). In the diving computer of Patent Literature 1, by providing a vibration generating means in addition to the display means and the alarm sound resonance means as warning means for the diver, the diving person can be surely recognized the warning of the diving computer. it can. Therefore, it is useful for improving the safety of divers.

  However, only divers can check the information of the diving computer in real time, and the manager on the water cannot immediately grasp the information of the diving computer. Therefore, safety management during diving depends on the diver's own judgment, and there is room for improvement. Since the attenuation of radio waves is large in water, it is not appropriate to transmit the information of the diving computer to the manager on the water using wireless communication. On the other hand, when wired communication is used, there is a problem that an extra communication cable interferes with the work of the diver.

  The management unit 2 is information management means for outputting and / or inputting information, and is composed of, for example, a personal computer. The information relay device 4 is a waterproof communication device having a short-range wireless communication function. The management unit 2 and the information relay device 4 are connected by a communication cable 3.

  The underwater terminal device 5 is a waterproof diving tool or underwater work equipment that performs at least one of input of information from the diver H and output of information to the diver H. The underwater terminal device 5 has a short-range wireless communication function of the same standard as the information relay device 4. Specifically, for example, diving computer (diving watch), biological information acquisition device (heart rate monitor, blood pressure monitor, thermometer, etc.), flow meter, earphone, microphone, photographing device (camera, video camera, etc.), multi-function portable terminal (Smartphones, tablets, etc.), measuring devices (metal detectors, roughness meters, etc.), cleaning devices (polishing devices, suction devices, etc.), construction tools (drills, crushers, etc.), moving devices (underwater scooters, underwater bikes, etc.) A short-range wireless communication function is mounted on a construction machine (underwater backhoe, underwater pump, etc.), underwater robot, etc., and used as the underwater terminal device 5. The information relay device 4 and the underwater terminal device 5 are configured to be connected by short-range wireless communication.

  Near field communication here means communication performed within a predetermined distance range (for example, within a range of several meters). Short-range wireless communication includes Bluetooth (registered trademark), ZigBee (registered trademark), WEAVE (registered trademark), NFC (Near Field Communication), Felica (registered trademark), UWB (Ultra Wide Band), TransferJet, RFID (Radio) Communication based on standards such as Frequency IDentification can be exemplified.

  In this embodiment, the management unit 2 is installed inside the support ship S. An air supply device 9 is installed on the upper deck of the support ship S. The information relay device 4 is mounted on the back of the diver H as a small terminal. The diver H is equipped with various underwater terminal devices 5 and diving equipment 6. The air supply device 9 and the diving tool 6 are connected by an air supply pipe 7.

  The communication cable 3 is disposed along the air supply pipe 7, and the communication cable 3 and the air supply pipe 7 are bound by a plurality of binding tools 8. Adjustment of the feeding length of the bundled communication cable 3 and the air pipe 7 is performed by, for example, an operator on the ship.

  As described above, when air-feeding diving (such as Hooker diving or helmet diving) is employed, the communication cable 3 can be accommodated in a compact manner by connecting the communication cable 3 along the air-feeding pipe 7. It is effective to prevent 3 from interfering with underwater work.

  The diver H wears the diving computer 5a, the biological information acquisition device 5b, the inclination sensor 5c, the flow meter 5d, the earphone 5e, and the microphone 5f as the underwater terminal device 5, and carries the photographing device 5g and the multifunctional portable terminal 5h. doing. The flow meter 5d detects the air flow rate in the air pipe 7. An underwater robot 5 i is provided as an underwater terminal device 5 at the bottom of the water.

  In the present invention, when the diver H performs underwater work, communication between the management unit 2 and the information relay device 4 is performed via the stable communication cable 3 that is hardly affected by the underwater environment. On the other hand, communication between the information relay device 4 and the underwater terminal device 5 is performed by short-range wireless communication with high convenience. Thereby, information is communicated in real time between the management unit 2 and the underwater terminal device 5 to support underwater work.

  Specifically, for example, information (such as no decompression diving time, decompression schedule, water depth, water temperature, diving time, etc.) held by the diving computer 5a is sequentially input from the diving computer 5a to the management unit 2. And the information of the diving computer 5a is shared between the diver H and the manager in the support ship S in real time. In this way, the manager in the support vessel S can appropriately manage and instruct the diving person H about the diving time and the ascent rate based on objective data.

  The biological information such as the heart rate, blood pressure, and body temperature of the diver H can be measured by the biological information acquisition device 5b, and the biological information can be sequentially input from the biological information acquisition device 5b to the management unit 2. If it does in this way, the manager in support ship S can grasp the living body information of diver H in real time. Therefore, even when a trouble occurs such as when the diver H loses physical condition, it is possible to respond appropriately and promptly.

  The inclination sensor 5c can detect the diver's inclination information (the diver's posture and movement) as one of the biological information, and the detection data can be sequentially input to the management unit 2. If it does in this way, the manager in support ship S can grasp the posture and movement of diver H in real time. For example, when the diver's posture does not change for a certain period of time or longer, it can be determined that the diver H has lost consciousness or cannot move. If the change in the posture of the diver H is abnormally severe, it can be determined that some trouble has occurred in the diver. Thus, by grasping the posture of the diver H and the change in the posture by the inclination sensor 5c, it becomes possible to appropriately deal with the diver H at an early stage. If the biological information acquired by the biological information acquisition device 5b and the inclination information of the diver H by the inclination sensor 5c are acquired together, the state of the diver H can be grasped and analyzed in more detail, so that the safety of underwater work is improved. It is beneficial to.

  By sequentially inputting the information of the flow meter 5d to the management unit 2, the information of the flow meter 5d can be shared in real time between the diver H and the manager in the support vessel S. As a result, the manager in the support vessel S can monitor the air supply status for the diver H, and it is possible to respond immediately even if a malfunction occurs in the air supply system such as the air pipe 7. Become.

  By connecting the earphone 5e and the microphone 5f to the management unit 2 via the information relay device 4, the earphone 5e and the microphone 5f can be made wireless. Thereby, the hole for penetrating the cable used for the communication formed in the diving suit of the diver H can be eliminated or reduced as compared with the conventional wired communication.

  By sequentially inputting data captured by the imaging device 5g to the management unit 2 from underwater, the video captured by the imaging device 5g can be displayed in real time on the management unit 2. In this way, the underwater situation can be grasped in real time from the water, which is useful for underwater observation work, inspection work for ships, and the like. Further, by inputting information from the management unit 2 to the photographing device 5g, it is possible to change settings such as the light amount and zoom of the photographing device 5g from the water. In this way, since it is not necessary to perform detailed operations and settings in the water, the diver H can be lightened.

  Data such as work schedules, drawing information, maps, etc. are input from the management unit 2 to the multi-function mobile terminal 5h, or between the manager and the diver H in the support vessel S using the multi-function mobile terminal 5h. You can also communicate. If it does in this way, since it becomes possible to exchange much information between the diver H and a manager, the improvement of workability | operativity and efficiency of underwater work can be aimed at.

  By inputting information to the underwater robot 5i from the management unit 2 via the information relay device 4, it is possible to give an instruction to the underwater robot 5i from the surface or change the settings of the underwater robot 5i. This makes it possible to perform input work from the water while the underwater robot 5i is underwater, which is advantageous for improving the work efficiency of the underwater work. Further, since it is not necessary for the diver H to perform a fine input operation or the like on the underwater robot 5i, the diver H can be lightened. This method can be applied even when a measuring instrument or a construction machine is used as the underwater terminal device 5.

  As described above, in the present invention, the management unit 2 on the water can monitor the information on the underwater terminal device 5 in real time and input data to the underwater terminal device 5. Workability can be improved. Moreover, the number of holes for penetrating the cable used for communication to the diving suit of the diver H by performing communication between the information relay device 4 and the underwater terminal device 5 in the water by short-range wireless communication. Can be eliminated or reduced. Since there are fewer cables, workability for underwater work can be secured.

  Further, if communication is performed between the management unit 2 and another management facility F using an Internet line or the like, information can be communicated between the underwater terminal device 2 and the management facility F in real time. It becomes possible. If the management unit 2 is made to function as one of the information repeaters in this way, it is possible to support underwater work from the management facility F that is away from the site where the underwater work is performed.

  When the information relay device 4 is attached to the diver H as in this embodiment, even when the diver H moves, the distance between the underwater terminal device 5 and the information relay device 4 provided by the diver H is always close. And underwater work can be performed in a stable communication state. That is, the diver H can perform underwater work in a wide range without worrying about the communicable distance between the underwater terminal device 5 and the information relay device 4.

  If the short-distance wireless communication can be performed between the information relay devices 4 of the respective divers H, information can be shared between the divers H. When the information of the underwater terminal device 5 and the information from the management unit 2 are shared between the divers H, the efficiency of underwater work can be expected.

In this embodiment, the information relay device 4 is separated from the diver H and installed in the water. As a diving mode, a scuba diving in which the diver H wears the cylinder 10 is adopted. Other configurations are the same as those of the previous embodiment shown in FIGS.

  A communication cable 3 is connected above the information relay device 4, and a weight 11 is suspended below the information relay device 4. The information relay device 4 is installed in the water by placing the weight 11 on the bottom of the water.

  By separating the information relay device 4 from the diver H and installing it in the water, the diver H does not need to be equipped with the information relay device 4 and the communication cable 3, so that the workability of underwater work is improved. It will be advantageous to improve. In particular, it is useful when adopting scuba diving that does not use the air pipe 7. The information relay device 4 is not limited to underwater work by the diver H, but can also be used as a communication means for controlling the underwater robot 5i, the construction machine, and the like from the management unit 2.

  When the information relay device 4 is installed in the water, the range within which the short distance wireless communication can be performed between the information relay device 4 and the underwater terminal device 5 is the range of action of the diver H. However, it is also possible to expand the range of action of the diver H by deploying a plurality of information relay devices 4 at intervals.

  When a plurality of information relay devices 4 are deployed, the position of each information relay device 4 may be measured. As a result, the information relay device 4 is used as a means of specifying the underwater position of the diver H, etc. by grasping which information relay device 4 is used by the diver H, the underwater robot 5i, etc. for communication.
