[Constitution]
FIG. 1 is a diagram showing an outline of a diving management system in the present embodiment. In addition to one or a plurality of divers, a crew member who performs various support operations for divers' operations and divers is on board each of the ships 10a and 10b. Each diver starts diving from the diver's ships 10a and 10b into the water, and when the diving work is finished, the divers float on the water surface and return to the divers' ships 10a and 10b again. Any one of the plurality of diving ships (here, the diving ship 10a) is called a command ship. The command ship represents a plurality of divers' ships and has a role of performing processing related to the management of divers, and gives various instructions and notifications to each diver. Hereinafter, when referring only to the diver's ship 10a, it is referred to as a command ship 10a, and when referring to the entirety of a plurality of divers' ships, it is referred to as a diver's ship 10a, 10b. In addition, although only one submarine ship other than the command ship is shown in FIG. 1, two or more submarine ships may be used.

  For divers 20a and 20b during diving, air is sent from each of the divers 10a and 10b through a long tubular hose called an air supply hose, and the divers 20a and 20b. Breathe in this air. In the illustrated example, air is sent to the diver 20a from a pump device 31a provided in the command ship 10a as a mechanism for sending air via an air supply hose 30a. In addition, air is sent to the diver 20b through an air supply hose 30b from a pump device 31b provided in the diver's ship 10b as a mechanism for sending air. These air supply hoses 30a and 30b are drawn out into the water by the crew members from the diver's ships 10a and 10b according to the descending speed during the period when the divers 20a and 10b are descending, and the divers 20a and 20b. During the ascending period, the crew member is pulled out of the water according to the ascending speed and is accommodated on the decks of the submarine ships 10a and 10b.

  The deck of the command ship 10a is provided with a GPS unit 101a (positioning means) that measures the position of the command ship 10a using a D-GPS (Differential-Global Positioning System) technique. Similarly, the GPS unit 101b for measuring the position of the diver's ship 10b is also provided on the deck of the diver's ship 10b. The position of the submarine ship 10b measured by the GPS unit 101b is notified to the command ship 10a by radio.

  The diver 20a is equipped with a transponder 201a and a vibrator 202a connected to the transponder 201a, and the diver 20b is equipped with a transponder 201b and a vibrator 202b connected to the transponder 201b. Has been. A transducer 102 that transmits and receives ultrasonic waves in water is provided on the bottom of the command ship 10a. The transmitter / receiver 102 (positioning means) transmits and receives ultrasonic waves to and from the transponders 201a and 201b attached to the divers 20a and 20b, so that the positions of the transponders 201a and 201b, that is, the divers 20a and 20b. A process for specifying each position is performed.

  Further, the transducer 102 transmits ultrasonic waves to the transponders 201a and 201b to vibrate the vibrators 202a and 202b attached to the divers 20a and 20b by remote control. The form of vibration at this time can be changed in various ways according to an instruction from the transmitter / receiver 102 using ultrasonic waves. By conforming, it is possible to notify the divers 20a and 20b of messages that can be expressed by Morse signals.

  Thus, the position of the diver's ship 10b is notified to the command ship 10a, and the position of the transponders 201a and 201b (that is, the divers 20a and 20b) is specified in the command ship 10a. Therefore, in the command ship 10a, all the positions of the divers 20a and 20b and the positions of the divers 10a and 10b can be specified.

  FIG. 2 is a block diagram showing an electrical configuration of the diving management system. In addition to the GPS unit 101a and the transmitter / receiver 102 described above, the command ship 10a includes a computer 11a that functions as a diving management device and a communication device 12a that is a communication unit that performs wireless communication in accordance with a wireless LAN (Local Area Network) standard. And an alarm device 13 having a speaker for performing sound notification and a lamp for performing light notification, and a control unit 14 for causing the transmitter / receiver 102 to transmit / receive ultrasonic waves based on an instruction from the computer 11a. Is provided. The computer 11a includes a control unit 111a having a CPU (Central Processing Unit), a ROM (Read Only Memory), and a RAM (Random Access Memory), programs executed by the control unit 111a, and various data used by the control unit 111a. A storage unit 112a that is a storage unit such as a hard disk, a display unit 113a that is a display unit having a liquid crystal panel and its driving circuit, and an operation unit 114a that is an operation unit having a pointing device and a keyboard. .

  In addition to the GPS unit 101b described above, the diver 10b is provided with a computer 11b and a communication device 12b. The GPS unit 101b, the computer 11b, and the communication device 12b are the same in hardware as the GPS unit 101a, the computer 11a, and the communication device 12a on the command ship 10a side, but are stored in the storage unit 12b of the computer 11b. The program is different from the program stored in the storage unit 12a of the computer 11a.

  The data stored in the storage unit 112a includes the transponder identifier assigned to the transponders 201a and 201b attached to the divers 20a and 10b, and the submarine ships 10a and 10b that supply air to the divers 20a and 10b. A database in which the submarine ship identifiers assigned to are associated with each other is included. In the example of FIG. 1, the transponder identifier assigned to the transponder 201a attached to the diver 20a and the diver ship identifier assigned to the command ship 10a are associated with each other. This means that the transponder identifier assigned to the mounted transponder 201b is associated with the diver's ship identifier assigned to the diver's ship 10b.

  Although not shown in the figure, this diving management system also includes an underwater telephone facility for making a call between the crew of the command ship 10a and the divers 20a and 20b.

[Operation]
FIG. 3 is a flowchart showing the operation of the control unit 111a of the computer 11a on the command ship 10a side. The control unit 111a performs the process of FIG. 3 according to the procedure described in the program stored in the storage unit 112a. In FIG. 3, when it is time to perform the processing after step S12 (step S11; YES), the control unit 111a (second specifying unit) uses the control unit 14, the transducer 102, and the transponders 201a and 201b. The position of each diver 20a, 20b is specified (step S12).

  Specifically, the control unit 111a controls the control unit 14 to cause the transmitter / receiver 102 to transmit a trigger signal having a predetermined format using ultrasonic waves. In response to the trigger signal, the transponders 201a and 201b attached to the divers 20a and 10b transmit a response signal having a predetermined format by ultrasonic waves. This response signal includes a transponder identifier assigned to each of the transponders 201a and 201b. The transponder identifier, ultrasonic transmission / reception time, and the like are supplied from the control unit 14 to the control unit 111a. Based on the transponder identifier, the control unit 111a identifies the transponders 201a and 201b that transmitted the response signals, and sets the positions of the transponders 201a and 201b (that is, the positions of the divers 20a and 20b) in the X, Y, and Z coordinates. Find the coordinate value expressed in the system. The control unit 111a associates the transponder identifiers of the transponders 201a and 201b attached to the divers 20a and 20b with the positions of the transponders 201a and 201b (that is, the positions of the divers 20a and 20b) and stores them in the storage unit 112a. To do.

  Note that the X coordinate axis and the Y coordinate axis of the X, Y, Z coordinate system here are coordinate axes orthogonal to each other in a horizontal plane, and the Z coordinate axis is a vertical coordinate axis orthogonal to both the X coordinate axis and the Y coordinate axis. It is. In addition, there are various known methods for underwater positioning using ultrasound. For example, registration of a new technology information system (NETIS) managed by the Japanese Ministry of Land, Infrastructure, Transport and Tourism No. One example is described in KTK-040007-A and the like, and using this makes it possible to realize more accurate positioning.

  Next, the control part 111a (1st identification means) specifies the position of each submarine ship 10a, 10b (step S13). As described above, the positions of the divers 10a and 10b are respectively measured by the GPS units 101a and 101b. Then, about the position of the command ship 10a, the control part 111a itself acquires from the GPS unit 101a, and specifies the position. As for the position of the other diver's ship 10b, the control unit 111a transmits a request signal for requesting the position from the communication device 12a to the communication device 12b of the diver's ship 10b. Since the control unit 111b of the warship 10b transmits the position information indicating the position acquired from the GPS unit 101b together with the submarine ship identifier, the control unit 111a receives this by the communication device 12a and specifies the position. . The control unit 111a associates the diver's ship identifiers of the divers 'ships 10a and 10b with the positions of the divers' ships 10a and 10b and stores them in the storage unit 112a. The positions of these divers 10a, 10b are represented by coordinate values in the X, Y, Z coordinate system, similarly to the positions of the divers 20a, 20b.

  Next, the control unit 111a transmits the positions of the identified divers 20a and 20b and the divers 10a and 10b from the communication device 12a to the communication devices 12b of the other divers 10b (step S14). ). And the control part 111a (a 3rd identification means, a display control means) is based on the position of each specified diver 20a, 20b and each diver's ship 10a, 10b from the diver's ship 10a, 10b. The positions of the air supply hoses 30a and 30b for supplying air to 20b are specified, and the positions of the divers 20a and 20b, the divers ship 10a and 10b, and the air supply hoses 30a and 30b are displayed on the display unit 113a. Display processing is performed (step S15).

  FIG. 4 is a diagram showing an example of a screen displayed on the display unit 113a of the computer 11a of the command ship 10a at this time. In the area on the right side of FIG. 4, X, Y, and Z coordinate values indicating the positions of the divers 20a and 20b and the divers 10a and 10b are displayed. The control unit 111a displays X, Y, and Z coordinate values representing the positions of the divers 20a and 20b and the divers 10a and 10b specified in steps S12 and S13 in this area. In the example of FIG. 4, the submarine ship assigned the number “1” is the command ship 10 a, and the X and Y coordinate values of this command ship 10 a are the origin “0, 0” of the X, Y coordinate system. It corresponds to. The diver's ship assigned the number “2” is the diver's ship 10b. The diver assigned with the number “1” is the diver 20a supplied with air from the command ship 10a, and the diver assigned the number “2” is sent from the diver ship 10b. It is a diver 20b to which air is supplied.

  In FIG. 4, the X and Y coordinate values of the positions of the divers 20a and 20b, the divers 10a and 10b, and the air supply hoses 30a and 30b are X (horizontal axis), Y It is shown on the coordinate plane (vertical axis). Below that, X and Z coordinate values of the positions of the divers 20a and 20b are shown on a coordinate plane of X (horizontal axis) and Z (vertical axis). Specifically, the positions with the double-circle figures g1 and g2 mean the positions of the divers 20a and 20b, and the positions with the single-round figures g11 and g12 indicate the positions of the divers 10a, The position of 10b is meant. The control unit 111a puts the graphics g1, g2, g11, and g12 at positions corresponding to the X, Y, and Z coordinate values of the divers 20a and 20b and the divers 10a and 10b specified in steps S12 and S13. indicate.

  Further, the positions where the dotted lines g21 and g22 are located mean the positions of the air supply hoses 30a and 30b. As described above, in the storage unit 112a, the transponder identifier assigned to the transponders 201a and 201b attached to the divers 20a and 20b and the submarine ships 10a and 10b that supply air to the divers 20a and 20b. A database in which the assigned diver's ship identifier is associated is stored. Therefore, the control unit 111a sets the air supply hose on the line segment associated with the database and connecting the position of the diver corresponding to the transponder identifier and the position of the diver's ship corresponding to the diver's ship identifier. Display a dotted line shape that means In the example of FIG. 4, the control unit 111a displays a dotted line graphic g21 indicating the position of the air supply hose 30a on a line segment connecting the graphic g1 and the graphic g11, and connects the line g2 and the graphic g12. A dotted line graphic g22 indicating the position of the air supply hose 30b is displayed on the top. In the example of FIG. 4, since the graphics g21 and g22 which mean the positions of the air supply hoses 30a and 30b do not intersect, the air supply hoses 30a and 30b do not intersect when viewed on the XY coordinate plane. .

  On the other hand, FIG. 5 is a diagram illustrating another example of a screen displayed on the display unit 113a. In the example of FIG. 5, since the graphics g21 and g22 which mean the positions of the air supply hoses 30a and 30b intersect, the air supply hoses 30a and 30b intersect when viewed on the XY coordinate plane. Become.

  In step S14, the control unit 111a transmits the positions of the specified divers 20a and 20b and the divers 10a and 10b to the other divers 10b. In response to this, the control unit 111b of the computer 11b of the diver's ship 10b is similar to the control unit 111a in the air supply hoses 30a and 30b that supply air from the diver's ship 10a and 10b to the divers 20a and 20b. Each position is specified, and display processing for displaying the positions of the divers 20a and 20b, the divers 10a and 10b, and the air supply hoses 30a and 30b on the display unit 113a is performed. That is, the same screen is displayed on the display unit 113a of the computer 11a of the diver's ship 10a and the display unit 113b of the computer 11b of the diver's ship 10b.

  Returning to the description of FIG. 3 again, the controller 111a (determination means) determines whether or not the air supply hoses 30a and 30b intersect (step S16). FIGS. 6A and 6B are views for explaining the concept when determining whether or not the air supply hoses intersect. Specifically, this determination is performed in the following procedure.

  First, the fact that two line segments that mean the positions of the two air supply hoses intersect each other means that the straight line AB passing through points A and B that mean the positions of one diver and the diver's ship respectively. The straight line CD that intersects the line segment CD that has points C and D as both ends, which mean the positions of the other diver and diver's ship, respectively, and that passes through the points C and D, has points A and B as both ends. The two conditions of intersecting with the line segment AB are satisfied at the same time. Here, the control unit 111a divides the XY coordinate plane into two regions using a certain straight line as a boundary line, and then the X and Y coordinate value groups belonging to the respective regions and both ends of the certain line segment. The X and Y coordinate values of the two points are compared. When the X and Y coordinate values of these two points exist one by one in the X and Y coordinate value groups belonging to the two regions divided by the straight line, the control unit 111a Judge that the line segment intersects.

  In the case of FIG. 6A, since two points C and D that are both ends of the line segment CD are respectively present in two regions divided by a straight line AB passing through the points A and B, one straight line AB. And line segment CD intersect. Similarly, since two points A and B which are both ends of the line segment AB are respectively present in two regions divided by the line CD passing through the points C and D, the line CD and the line segment AB intersect each other. doing. Therefore, in this case, since both of the two conditions described above are satisfied at the same time, the air supply hoses represented by the two line segments AB and CD each intersect.

  On the other hand, in the case of FIG. 6B, one of the two conditions described above is not satisfied. Therefore, in this case, the air supply hoses represented by the two line segments AB and CD each do not intersect.

  When there are three or more divers, the control unit 111a selects any two of the three or more air supply hoses as one set, and makes the same determination as above for the two. This process may be performed for all groups included in three or more air supply hoses.

  Returning to the description of FIG. 3, when the control unit 111a (notification unit) determines that the air supply hoses 30a and 30b intersect (step S17; YES), the controller 111a (notification unit) determines whether or not the air supply hoses intersect. A notification process for notification is performed (step S18). Specifically, the control unit 111a emits a sound from the alarm device 13 and lights the light, and further corresponds to each of the divers 20a and 20b using the crossing air supply hoses 30a and 30b. The control unit 14 is instructed to designate a transponder identifier and transmit an alarm signal to the transponders 201a and 201b. In response to this instruction, the transmitter / receiver 102 transmits an alarm signal designating a transponder identifier. When the transmitted alarm signal is received by each of the transponders 201a and 201b corresponding to the designated transponder identifier, the transponders 201a and 201b vibrate the vibrating bodies 202a and 20b according to the alarm signal. A drive signal meaning starting is supplied to vibrate the vibrating bodies 202a and 202b. By the sounding and lighting by the alarm device 13, the crew member on the deck of the divers 10a and 10b knows that the air supply hoses are in an intersecting state. Further, due to the vibration of the vibrating bodies 202a and 202b, the divers 20a and 20b know that the air supply hose supplying air to itself intersects with other air supply hoses.

  According to this notification, the crew of the command ship 10a does not intersect the air supply hoses 30a, 30b while taking into account the positional relationship between the divers 20a, 20b and the air supply hoses 30a, 30b displayed on the display unit 113a. The divers 20a and 20b are urged to move their positions until such a state is reached. Specifically, the direction and distance of movement are transmitted to the divers 20a and 20b through a call using the above-described underwater telephone facility, or the vibrations 202a and 202b are remotely controlled to vibrate according to the Morse code system. By performing the above, the direction and distance of movement are transmitted to the divers 20a and 20b.

  In the case of the latter notification, the crew member operates the operation unit 114a of the computer 11a to send a message to the divers 20a and 20b and the divers 20a and 20b using the crossed air supply hoses 30a and 30b. When the transponder identifiers of the transponders 201a and 201b are input, the control unit 111a designates these transponder identifiers and instructs the control unit 14 to transmit a signal including the message signal to the transponders 201a and 201b. In response to this instruction, the transducer 102 transmits a signal designating the transponder identifier. When the transmitted signal is received by each of the transponders 201a and 201b corresponding to the designated transponder identifier, the transponders 201a and 201b vibrate so as to express the message in a manner of vibration based on the Morse signal. 202a and 202b are vibrated.

  In step S17 of FIG. 3, when determining that the air supply hoses do not intersect (step S17; NO), the control unit 111a determines whether the notification process in step S18 is being performed (step S19). If the notification process is not being performed (step S19; NO), the control unit 111a returns to the process of step S11. If the notification process is being performed (step S19; YES), the control unit 111a has stopped the notification process. (Step S20), the process returns to Step S11.

  According to the embodiment described above, the computer 11a, which is a diving management device, notifies the decks of the divers 10a, 10b by using the alarm device 13 when determining that the air supply hoses have crossed. It is possible to notify a crew member who is present that the air supply hose is in a crossed state, and the computer 11a causes the vibrators 202a and 202b attached to the divers 20a and 20b to vibrate. It is possible to notify the divers 20a and 20b that the air hoses are intersecting. According to the present embodiment, it is possible to reduce the risk of various problems and accidents for divers and realize safe diving by such alerting.

(Modification)
The present invention is not limited to the above-described embodiment, and the following modifications are possible. Further, the following modifications may be combined with each other.
(Modification 1)
In the embodiment, the computer 11a provided in the diver's ship 10a performs the above-described processing. However, for example, a computer installed on the land or a computer installed in a ship that is not a diver's ship Processing may be performed. In this case, the communication devices are connected to the computers of the divers 10a and 10b and the computers of the land or ship so that these computers can transmit data to each other via a network such as the Internet. Wireless connection is established.

(Modification 2)
The method for determining whether or not the air supply hoses intersect is not limited to that exemplified in the embodiment, and the air supply hoses intersect based on the position of the diver's ship and the position of the diver. Any method may be used as long as it can be determined.

(Modification 3)
In the embodiment, the notification process is performed when it is determined that the air supply hoses are intersecting, but the method of the notification process is not limited to that exemplified in the embodiment. For example, a light emitter may be attached to the divers 20a and 20b, and the computer 11a may perform notification processing by causing the light emitter to emit light by remote control. Here, if the structure which concerns on the diver 20a in this modification is illustrated, it will become a structure as shown, for example in FIG. A light emitter 203a such as an LED (Light Emitting Diode) is attached to the frame of the underwater mask worn by the diver 20a, and the light emitter 203a and the transponder 201a are connected. The control part 111a (notification means) is the notification process for notifying whether or not the air supply hoses are intersecting, and the divers 20a and 20b using the intersecting air supply hoses 30a and 30b. The control unit 14 is instructed to designate a transponder identifier corresponding to each of them and to transmit an alarm signal to the transponders 201a and 201b. In response to this instruction, the transmitter / receiver 102 transmits an alarm signal designating a transponder identifier. When the transmitted alarm signal is received by each of the transponders 201a and 201b corresponding to the designated transponder identifier, the transponders 201a and 201b supply drive signals to the vibrators 202a and 20b according to the alarm signal. In addition, a drive signal is supplied to the light emitter 203a to emit light. In addition, although the light-emitting body 203a was attached to the frame of the underwater mask, it is not limited to this place, and the point is that it may be any place that can be clearly seen by the diver during work in water.

(Modification 4)
In the embodiment, the computer 11a specifies the position of the diver's ship, the position of the diver and the position of the air supply hose, respectively, and displays them, and performs the notification process when the air supply hose intersects. Instead, the position of the diver ship, the position of the diver, and the position of the air supply hose may be specified and displayed. This is because a crew member who sees such a display can know whether or not the air supply hoses are crossing by looking at these positional relationships. In this way, even if only the position of the diver's ship, the position of the diver and the position of the air supply hose are displayed, it can be a means capable of notifying whether or not the air supply hoses are intersecting. That is, the present invention provides a first specifying means for specifying the positions of a plurality of ships provided with a mechanism for sending air to the divers via a hose, and a plurality of the divers who send air from each of the ships. Based on the second specifying means for specifying the positions, the positions of the plurality of ships specified by the first specifying means, and the positions of the plurality of divers specified by the second specifying means, the hose A third specifying means for specifying a position, each position of a plurality of ships specified by the first specifying means, each position of a plurality of divers specified by the second specifying means, and the third It is possible to provide a diving management device comprising display control means for causing the display means to display the position of the hose specified by the specifying means.

  In addition, the computer 11a specifies the position of the diver's ship and the position of the diver, and even if the position of the air supply hose is specified, the computer 11a does not display this but performs a notification process when the air supply hose crosses. Just be fine. This is because the crew member can know how the air supply hoses intersect by such display and notification. In this way, the position of the diver's ship and the position of the diver can be displayed, and it is possible to notify whether or not the air supply hose is intersecting only by performing the notification process when the air supply hose intersects. It can be a means. That is, the present invention provides a first specifying means for specifying the positions of a plurality of ships provided with a mechanism for sending air to the divers via a hose, and a plurality of the divers who send air from each of the ships. Based on the second specifying means for specifying the positions, the positions of the plurality of ships specified by the first specifying means, and the positions of the plurality of divers specified by the second specifying means, a plurality of positions Diving management characterized by comprising: a judging means for judging whether or not the hoses intersect; and a notifying means for making a notice when the judging means judges that the plurality of hoses are intersecting. An apparatus may be provided.
