Description

The present invention relates to a diving mask and a diver support system that support the safety of underwater workers working underwater.

Underwater workers (divers) may dive into the water to perform work, such as when creating a foundation for the seabed or when investigating underwater or the seabed. The state of the diver is confirmed by the workers on the ship by voice, breath, etc., but it is difficult to grasp the details. Therefore, a system that supports the safety of divers has been developed.

For example, Japanese Patent Application Laid-Open No. 2018-39438 (Patent Document 1) discloses an underwater work support method and system capable of improving the safety and workability of underwater work.

Japanese Unexamined Patent Publication No. 2018-39438

According to the invention as described in Patent Document 1, the safety of the diver is improved by sharing the diving time and the like with the person on board. However, even if such an invention is provided, problems may occur due to the circumstances peculiar to the diver. For example, if the diver has some kind of illness and it develops, it is possible that the diver is ill at a level that he / she does not even notice and is weaker than usual. In the above invention, such a problem can be detected as an abnormality, but the state of the diver cannot be confirmed. Therefore, when a worker on board detects an abnormality in the diver, the situation of the diver cannot be confirmed, but it is urgent. There was the problem of being able to suffer from decompression sickness.

Therefore, the present invention provides a diving mask and diving that gives a worker on the water useful information for selecting a rescue method for the diver when an abnormality occurs while the diver is working underwater. The purpose is to provide a support system.

In order to solve the above-mentioned problems, the diving mask worn by the underwater worker according to the present embodiment is an inward direction capable of imaging at least one eye of the underwater worker, which is one of the underwater devices worn by the underwater worker. The configuration is characterized by including an image pickup unit and a regulator device for an underwater worker to breathe underwater.

According to this configuration, even if the underwater worker is working underwater, the eye portion of the underwater worker can be imaged. This makes it possible to provide a diving mask for the underwater worker to check the eyes of the underwater worker when an abnormality occurs in the underwater worker.

Further, the diver support system according to the embodiment of the present invention includes a diving mask as described above, an underwater device worn by an underwater worker, and a monitoring device connected to the underwater device by telecommunications. The apparatus is further configured to include a depth measuring unit.

According to this configuration, when an abnormality occurs in the underwater worker, the water worker can check the eyes of the underwater worker. Thereby, it can be used as a judgment material when selecting a rescue method for an underwater worker, and an optimum rescue method can be selected according to the condition of the underwater worker.

According to the present invention, a diving mask and a diving mask that give a worker on the water useful information for selecting a rescue method for the diver when an abnormality occurs while the diver is working underwater. A diver support system can be provided.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 shows the configuration of the diver support system 1 according to the present embodiment. The diver support system 1 includes an onboard device 30 (hereinafter referred to as an onboard device) and an underwater device 10 (hereinafter referred to as an underwater device). The onboard device 30 does not have to be on the ship and may be on land such as a shore by the sea.

The underwater device 10 is basically a device attached to a diving suit (not shown) worn by a diver, and has a sounding unit 11, a sound collecting unit 12, an inward imaging unit 13, an outward imaging unit 14, and a depth measuring unit. It is equipped with 15. Further, as shown in FIG. 1, the electrocardiogram measuring unit 16 may be provided. An air supply hose 17 is attached to the diving suit, and air can be sent from the ship through the air supply hose 17 so that a diver in the water can breathe. The air supply hose 17 has the flexibility to follow the movement of the diving diver, and the diver can move in the water without being greatly restricted by the air supply hose 17.

In the present embodiment, the underwater device 10 and the onboard device 30 are electrically connected by an electric wire 18 capable of telecommunications. Specifically, the sounding unit 11, the sound collecting unit 12, the inward imaging unit 13, the outward imaging unit 14, and the depth measuring unit 15 are the monitoring device 32 and electricity, which are a part of the onboard device described in detail later. It is connected. By arranging the electric wire in combination with the air supply hose 17, the risk of disconnection can be reduced and the electric wire can be configured so as not to interfere with the work of the diver.

The sounding unit 11 is, for example, a speaker of an underwater wired telephone device, and transmits to a diver the sound collected by the communication unit 33, which is a part of the monitoring device 32 on the ship (for example, the voice of a worker on the ship). be able to. The sound collecting unit 12 is, for example, a microphone of an underwater wired telephone device, and can collect the voice of a diver underwater and transmit it to the talking unit 33 on the ship. These functions enable real-time communication between underwater divers and workers on board. The sound collecting unit 12 can also collect and transmit the breath sounds of the diver. Therefore, the worker on board can know whether or not the diver is breathing.

The inward imaging unit 13 is an eye confirmation camera equipped with an imaging element such as a CCD or CMOS, which is mounted inside a diving mask worn by a diver on his head (see FIG. 3), and is a diving mask. The inside of 40 can be imaged. The imaging unit is provided in front of the mask so that at least one eye of the diver can be seen. In the present embodiment, the imaging unit is attached to the inside of the diving mask 40, but since the inside of the diving mask 40 may be flooded for some reason, it is desirable to have a performance that can be used even in water. .. In addition, it is desirable to have pressure resistance so that there is no problem even at a position where the water depth is deep. If it is possible to image the eye of the diver during diving, the inward image pickup unit 13 may be provided outside the diving mask. In order to give the inward image pickup unit 13 water resistance and pressure resistance, for example, it is conceivable to house the image pickup device in a housing made of an aluminum alloy or the like. Further, the housing or the image pickup portion may be coated with a pressure resistant waterproof resin and filled. With such a structure, it is possible to have a pressure resistance of 10 atm or more.

Further, the inward imaging unit 13 may include one or more internal lighting units 19 such as a light using an LED. As a result, even if the environment is insufficient for taking an image in water, the brightness of the eye portion can be adjusted according to the surrounding conditions, and the inward image pickup unit 13 can take a clear image. .. FIG. 4 is a schematic view of the inward image pickup unit 13 in the present embodiment as viewed in the direction of arrow A in FIG. 3, which will be described in detail later, that is, as viewed from the front, and is a schematic view of the front surface of the substantially quadrangular inward image pickup unit 13. Internal lighting units 19 are provided at the four corners. In the present embodiment, the inward image pickup unit 13 has a substantially square columnar shape, but is not limited to this, and can have any shape such as a substantially polygonal columnar shape and a substantially cylindrical columnar shape.

By providing the headlight unit 19, not only the quality of imaging is improved, but also other advantages can be obtained. For example, the reaction of the diver can be confirmed by blinking the headlight unit 19. As a result, even if the image displayed on the display unit 34, which will be described later, does not change for a certain period of time, the surface worker may have some device failure, an abnormality in the diver, or simply move. You can judge whether it was just not there. Therefore, it is preferable to configure the headlight unit 19 to be turned on, off, and the amount of light thereof so that the water worker can also control it.

Further, by blinking the headlight unit 19, the abnormality can be transmitted to the diver. Normally, the water worker transmits information to the diver via the sounding unit 11, but by using the blinking of the headlight unit together, the diver can be alerted even if the diver cannot hear the voice. can. Further, if the sounding unit 11 malfunctions, the underwater worker may not be able to grasp the failure. However, by blinking the headlight unit, the underwater worker sends a call to the diver, and the diver can detect that the sounding unit 11 is out of order. The blinking of the headlight unit 19 may be transmitted as a Morse code by combining, for example, lighting for a relatively short time and lighting for a longer time. This makes it possible to convey simple instructions.

The outward image pickup unit 14 is a work camera equipped with an image sensor such as a CCD or CMOS and provided so that the direction in which the diver is facing can be seen (see FIG. 3), and is a work camera that can be used underwater and is used for diving. The outside of the mask 40 can be imaged. The outward image pickup unit 14 also has water resistance and pressure resistance, and can be used even at a position where the water depth is deep. The outward image pickup unit 14 may also include one or more headlight units 20 (for example, a light using an LED) as shown in FIG. Further, as with the internal lighting unit 19, it is preferable that the headlight unit 20 is turned on and off, and the amount of light thereof can be controlled by a water worker. The image pickup unit is attached to the outside of the diving mask, for example, and can take an image in the direction in which the diver is facing, that is, a scene similar to the field of view of the diver. In addition, the work performed by the diver can be imaged. The outward image pickup unit 14 can also have an arbitrary shape like the inward image pickup unit 13.

The depth measuring unit 15 is, for example, a depth meter, and can measure how deep the worker is now. When a diver dives, depth information is important, and the diver manages diving time, ascent speed, etc. based on the depth information obtained by the depth measuring unit.

The electrocardiogram measuring unit 16 is, for example, a device provided with a plurality of electrodes, and is attached to a worker's chest, limbs, or the like. It is possible to acquire the electrical activity generated by the operation of the heart by the electrodes. The acquired waveform is delivered to the monitoring device 32 via the electric wire 18. You can also get a heartbeat.

For example, an electrocardiograph can be used for the electrocardiogram measuring unit 16. The electrocardiograph measures the electrocardiogram waveform by attaching an electrode to a predetermined position. When a diver carries an electrocardiograph to store measurement records, and by arbitrary wireless communication such as WiFi (registered trademark) and Bluetooth (registered trademark), measurement information is transmitted to the electrocardiogram receiving device and the electrocardiogram receiving device is used. Can transmit measurement information to the monitoring device 32 via the electric wire as described above. When it is necessary to apply water resistance and pressure resistance to the electrocardiograph, for example, the entire electrocardiograph may be caulked, or the electrocardiograph may be housed in an arbitrary container and the container may be filled with caulking material. ..

Since the electrodes are transmitted from the electrodes to the electrocardiograph via electric wires, the diver can wear the dry suit by passing the electric wires through the neck, for example. Alternatively, waterproofing inside the dry suit can be ensured by making an opening at an arbitrary place in the dry suit, attaching it through an electric wire through the opening, and applying water resistant treatment such as caulking to the opening. .. In the case of wet suits, it is not essential to apply the above water resistant treatment.

Of the electric wires 18, the electric wires used for the devices provided in the diving mask (for example, the sound collecting unit 11, the sound collecting unit 12, the inward image pickup unit 13, etc.) are provided so as to penetrate the exterior of the lower part of the diving mask. Be done. In addition, water leakage and pressure damage due to diving are prevented by using electric wires having water resistance and pressure resistance at least in places exposed to water. As a result, it is possible to reliably supply power to underwater devices such as each image pickup unit, and to reliably transmit images, sounds, and the like captured by them.

Further, the onboard device 30 includes an air supply device 31 and a monitoring device 32. The monitoring device 32 is a device for monitoring the data of the underwater device 10 and confirming or managing the state of the diver. The monitoring device 32 includes a calling unit 33, a display unit 34, and a storage unit 35.

The calling unit 33 is, for example, an underwater wired telephone device, and can transmit voice to the sounding unit 11 and the sound collecting unit 12, and can be used by a diver and a water worker to have a conversation. ..

The display unit 34 is, for example, a computer display, and can display an image such as an image captured by each of the image pickup units 13 and 14 described above. Further, the value of the depth measuring unit 15 and its history may be displayed with time, or information such as the passage of time of diving may be displayed. Further, the waveform or the like acquired by the electrocardiogram measuring unit 16 may be displayed. The display unit 34 allows the worker on board to grasp the state of the diver, the work content, and the state in the water in real time, and give instructions or alerts to the diver as necessary. The display unit 34 may be able to adjust the brightness, saturation, and the like of the displayed image. Further, as described above, the water worker can control the lighting and extinguishing of the internal lighting unit 19 and the headlight unit 20 and the amount of light thereof. This makes it possible to improve the visibility of the displayed image. In addition, the amount of light can be adjusted so that the brightness of the headlight unit does not adversely affect the diver. The adjustment of the display image may be executed by performing image processing on the image transmitted from each of the image pickup units 13 and 14, and the setting of the aperture value, ISO sensitivity and the like on each image pickup unit 13 and 14 side. It may be performed by transmitting a signal to adjust.

The storage unit 35 is a recording medium for recording various information. The storage unit 35 is realized, for example, a DRAM, an SRAM, a flash memory, an MRAM, a ReRAM, a FeRAM, an SSD (Solid State Device), a hard disk, another storage device, or a combination thereof as appropriate. The storage unit 35 has an image such as an image captured by the inward image pickup unit 13, an image such as an image captured by the outward image pickup unit 14, a sound acquired by the sound collecting unit 12, and an image acquired by the call unit 33. It is possible to store information such as the sound, the value acquired by the depth measuring unit 15, and the electrocardiogram waveform measured by the electrocardiogram measuring unit 16. The information stored in the storage unit 35 can be displayed on the display unit 34. It is also possible to move the information stored in an external computer for display, image processing, data transmission via arbitrary wired or wireless communication, and the like.

The air supply device 31 is, for example, a compressor, and can send compressed air to the diver through the air supply hose 17.

FIG. 2 is a schematic view showing a display unit 34 of the monitoring device 32 in the present embodiment. As shown in FIG. 2, the display unit 34 has a plurality of display areas 34a to 34d. The first display area 34a displays an image captured by the outward image pickup unit 14. The second display area 34b shows a schematic diagram of an image captured by the inward image pickup unit 13. That is, the eyes of the diver are displayed in the second display area 34b.

The third display area 34c is the dive start time when the diver started diving, the current time, the dive time during which the diver continues to dive, and the current depth and dive measured by the depth measuring unit 15. The maximum depth of is displayed. For example, from the third display area 34c shown in FIG. 2, it can be seen that the dive is started at 12:00 and the dive is performed for 60 minutes until 13:00, which is the current time. In addition, it can be seen that the diver is currently at a depth of 9.99 m and is diving to a maximum depth of 19.99 m in the dive. The fourth display area 34d displays the waveform of the electrocardiogram of the diver measured by the electrocardiogram measuring unit 16.

In the present embodiment, the above-mentioned contents are displayed in each display area of the display unit 34, but alternative or additional contents may be displayed. For example, a graph showing the relationship between the dive time and the depth of the diver may be displayed. Further, it may be configured so that the water worker can arbitrarily switch the display content of each display area.

FIG. 3 is a schematic view of a portion of the diving mask 40 worn by a diver and located in front of the face. In the present embodiment, the diving suit worn by the diver is described assuming a Hooker type, but may be a helmet type or a scuba type.

In the case of the scuba type, instead of the air supply hose 17, the diver is provided with an air cylinder, a tank, or the like, and air is supplied from the tank. Since the air supply hose 17 is not required, the degree of freedom in the range of movement is high as compared with other methods. For example, if it is a Hooker type or the like, it cannot be separated from a ship or the like equipped with an air supply device 31 by a certain distance or more, but if it is a scuba type or the like, it can move without the limitation. It should be noted that in the case of the scuba type, the electric wire for telecommunications between the onboard device 30 and the submersible device 10 cannot be combined with the air supply hose because the air supply hose 17 is not required.

The communication can be performed wirelessly, but it is not suitable for long-distance transmission in water because the attenuation of radio waves and electromagnetic waves is larger than in air, and it is necessary to lengthen the wavelength in order to use it. The amount of information that can be transmitted is small. Therefore, it is difficult for the underwater device 10 and the monitoring device 32 to directly perform wireless communication. Therefore, although it is desirable to perform telecommunications by wire, the advantage of the scuba type, which does not require an air supply hose and has a high degree of freedom of movement, is reduced. Therefore, in the scuba type, it is effective to perform communication between the onboard device 30 and the underwater device 10 on the water by using a relay device arranged on the water. The relay device can be provided, for example, in a floater configured to float on water.

The relay device is connected to the underwater device 10 by wire by an electric wire or the like, and can transmit information. Further, it is connected to the monitoring device 32 by arbitrary wireless communication and can transmit information. In this case, the monitoring device 32 includes a wireless communication unit capable of transmitting and receiving by wireless communication. By providing the relay device, the diver can work while communicating with the underwater device 10 even at a position away from the onboard device 30. Further, the diver may be configured to be able to tow the floater by the above electric wire or a separately provided towing cable or the like. That is, if the diver is far away from the floater, the floater (and relay device) may be configured to move as the diver moves. As a result, the diver needs to be equipped with an electric wire or the like to be connected to the relay device, but can work underwater without significantly limiting the range of action as compared with the Hooker type diving.

Further, an underwater radiotelephone device can also be used for the sounding unit 11, the sound collecting unit 12, and the talking unit 33. As a result, the conversation between the talking unit 33, the sounding unit 11, and the sound collecting unit 12 can be performed without using the relay device. By using the underwater radiotelephone device for a call, even if an abnormality occurs in the transmission via the relay device such as the image on the display unit 34 being disturbed, it is possible to communicate between the diver and the water worker. can. Therefore, the diving work can be performed more safely.

As described above, since the air supply hose does not exist in the scuba type, the electric wire connecting the relay device and the underwater device 10 cannot be combined with the air supply hose. Therefore, it is necessary to be careful not to easily break the wire by making the wire thicker or combining it with some strong parts.

In the present embodiment, as shown in FIG. 3, an inward image pickup unit 13 is provided so as to image the left eye of the diving mask 40. It does not have to be near the left eye, and may be provided near the right eye at a position where both eyes can be seen, as long as the inward image pickup unit 13 can image at least one eye. Further, a plurality of inward-facing imaging units may be provided so that each inward-facing imaging unit can image either the left or right eye unit. Further, the position of the inward image pickup unit 13 should be arranged at a position where the eye can be imaged and the influence on the work of the diver is small, not in front of the eye. An example of such a position is, for example, in a diving mask as shown in FIG. 3, a position corresponding to the diver's eye in the left-right direction and a height corresponding to the nose in the vertical direction. This is the area corresponding to the position. Therefore, it is preferable to dispose of it about 1 cm to several cm below the center of the diver's eye. It does not have to be directly under the eye, and may be offset to the left or right with respect to the eye according to the structure of the diving mask. By attaching the inward image pickup unit 13 to the mask so as to be arranged in the area, the diver's eyes can be imaged while ensuring the diver's field of view.

FIG. 5 is an exemplary schematic diagram of the positional relationship between the diver and the inward image pickup unit 13 as viewed from the side. It is preferable that the optical axis of the inward image pickup unit 13 has an elevation angle θ of about 20 to 40 degrees with respect to the horizontal. The position of the image pickup unit can be adjusted in elevation angle and mounting position according to the position of the diver's eye, and therefore, the image can be taken at the optimum position for each diver. Further, when the inward imaging unit 13 is arranged in the diving mask, an anti-fog gel or a spray may be applied to the light receiving unit in order to prevent fogging and dirt on the light receiving surface of the inward imaging unit 13 during diving. Then, a part of the air supplied to the diving mask may be branched so as to hit the light receiving surface. In addition, the diver can operate the regulator to send a large amount of air into the diving mask to remove fogging and the like.

The diving mask 40 includes the above-mentioned outward image pickup unit 14 and a regulator 42 for breathing with the air sent by the air supply hose 17. The regulator 42 is a so-called second stage regulator, and the regulator 42 is connected to a first stage regulator 41 (so-called first stage) (not shown) via a hose 43. The regulator 41 first decompresses the compressed air sent from the air supply device 31 via the air supply hose 17, and supplies the decompressed compressed air to the regulator 42 via the hose 43. The regulator 42 can further decompress the decompressed compressed air to the extent that the diver can breathe, and supply the air to the diver. In the present embodiment, the diving mask 40 is shaped so as to cover only the face area, but may be in the form of a hollow cylindrical mask that covers the entire head.

As mentioned above, the diver dives into the water and performs work such as checking the seabed. At this time, the worker on board can confirm the rough situation of the diver by talking with the diver and by checking the breath sounds. The situation can also be grasped by confirming an image such as an image acquired by the outward image pickup unit 14 on the display unit 34 of the monitoring device 32 on the ship. Therefore, even if an abnormality occurs in either the sound or the image, the presence or absence of the abnormality can be inferred by checking the other. Further, when the electrocardiogram measuring unit 16 is provided, the monitoring device 32 makes a sound when the monitoring device 32 cannot acquire the waveform of the electrocardiogram, or when the acquired waveform is disturbed beyond a preset threshold value. Alternatively, it may be configured to issue some kind of alarm such as blinking a kind of light. As a result, when the alarm is issued, the situation can be quickly grasped when an abnormality occurs by combining it with confirmation of at least one of voice and image.

Here, for example, when the sound from the diver is interrupted and there is an abnormality in the image obtained by the outward image pickup unit 14, it is presumed that some abnormality may have occurred in the diver. When such a situation arises, it will be necessary to take measures as described below in order to rescue the diver.

The cause of this abnormality may be that some object collides with the diver and loses consciousness, or the mask etc. is partially removed and it becomes impossible to breathe, but one of the other causes is It is possible that the diver will develop some kind of illness.

When a diver develops some kind of illness during a dive, it may be possible to detect some abnormality by interrupting the sound. However, it is difficult to confirm the detailed situation only by voice. It is also difficult to confirm with the image of the outward image pickup unit 14. Moreover, even if the waveform of the electrocardiogram is seen, it is difficult to judge the presence or absence of an abnormality without specialized knowledge. Therefore, when the diver support system 1 and the diving mask 40 according to the present embodiment are used, the state of the eye can be seen by the inward image pickup unit 13, and the state of the diver can be seen by this. Can be estimated. The condition of the eye is, for example, whether or not the pupil is open.

If an illness develops, it is necessary to rescue the diver, but there are multiple possible responses to the rescue, depending on the degree of urgency. For example, if there is an immediate risk of life-threatening and immediate rescue is required even when other risks are taken into consideration (hereinafter referred to as the first condition), a method that is life-threatening but suppresses other risks. There is a case where it should be rescued (hereinafter referred to as the second state).

As an example of the rescue method in the first state, a method of forcibly pulling up the diver from the water to near the surface of the water using the air supply hose 17 and rescuing the diver without checking the state of the diver (hereinafter referred to as “the rescue method”). There is a first rescue method). This method has the advantage that the diver can be withdrawn immediately. However, as the water pressure fluctuates as it is lifted from the water, the gas inside the diver's body expands as it approaches the surface of the water. As a result, if the diver is unconscious and the airway is blocked, there is a disadvantage that he may develop diseases such as air embolism and decompression sickness. For this reason, it is preferable not to select the first rescue method unless it is urgent.

Although it is not as urgent as the first state, as an example of the rescue method when it is decided that rescue should be done (in the case of the second state), another diver on board (hereinafter referred to as the second diver) There is a method (hereinafter referred to as a second rescue method) in which a diver (hereinafter referred to as a first diver) who has been submerged earlier is assisted and rescued by submerging the diver in the water. .. In this method, the second diver who dives for rescue can withdraw while securing the airway of the first diver. As a result, the first diver can be rescued while reducing the concern that symptoms such as the first rescue method will develop. However, the second rescue method has a disadvantage that it takes longer than the first rescue method.

If an abnormality occurs in an underwater diver, the workers on board must choose which of the multiple rescue methods described above will be used for rescue. This choice is urgent and cannot be determined over time, as the slower the rescue, the less likely it is to survive, and the decision must be made promptly based on the information at the time the abnormality was discovered.

Here, according to the diver support system 1 and the diving mask 40 according to the present invention, the onboard worker can confirm the state of the diver by the inward image pickup unit 13, which helps to quickly determine the rescue method selection. Become. Specifically, the rescue method can be selected by confirming whether or not the pupil of the eye imaged by the inward image pickup unit 13 attached so that the state of the pupil can be visually recognized is open.

For example, in a situation where it is considered that an abnormality has occurred, such as the image of the outward image pickup unit 14 does not change, or there is no sound or breath sound to be heard from the call unit 33, the display unit 34 of the monitoring device 32 is confirmed and diving. If the pupil of the fighter is open, it can be inferred that the diver is unconscious. Therefore, it can be determined that there is an urgency and that the first rescue method should be selected. Thereby, the diver can be rescued more effectively.

Further, in the above situation, if the diver's pupil is normal, it can be inferred that the diver has not completely lost consciousness. Therefore, it can be determined that the second rescue method should be selected. As a result, the diver can be lifted onto the ship without unnecessarily giving the diver the risk of causing air embolism or the like.

As described above, according to the diving mask 40 and the diver support system 1 according to the present embodiment, even if a situation occurs in which the diver loses consciousness during diving, it is appropriate to rescue the diver according to the urgency. You can choose any method.

Further, according to the diver support system 1 according to the present embodiment, the situation at the time of abnormality can be obtained in real time. Therefore, when the diver is rescued and transported to the medical institution, the situation is detailed to the medical institution in advance. Can be told to. For example, by transmitting the image of the inward image pickup unit 13, the state of the pupil and the like can be confirmed before the doctor examines the diver. Further, by transmitting the waveform or the like acquired by the electrocardiogram measuring unit 16, the doctor can confirm the electrocardiogram or the like of the diver including the time when an abnormality occurs. Therefore, since the condition of the diver can be estimated in advance and preparations are made according to the condition, more complete medical treatment can be received. In addition, it is possible to receive medical support at an early stage, such as providing first aid while contacting a doctor or the like by telephone or the like before transporting to a medical institution.

Further, as described above, the display unit 34 of the monitoring device 32 can display the diving depth and the diving time by the diver. In the past, the diver himself confirmed the depth gauge provided by the diver and shared the information with the workers on board via the telephone unit to manage safety. However, according to the diver support system according to the present invention, the diving depth, the dive time, the ascent speed, the timing of decompression stop, etc., can be used by the worker on board to determine the diving position of the diver. It is possible to grasp information such as real time and implement safety management. For example, by storing the decompression table provided by the Japan Diving Association in the monitoring device 32 and combining it with the value measured by the depth measuring unit 15, more accurate diving time management can be performed. ..

As a result, the diver can take appropriate actions during diving according to the instructions from the workers on board, and can prevent decompression sickness. In addition, since the diver can perform safety management related to diving according to the instruction from the worker on the ship, he / she can concentrate on the work.

Further, when combined with other information of the call unit 33 or the display unit 34, the diving depth of the diver immediately before the above-mentioned abnormality can be grasped, so that it is determined whether or not a problem related to water pressure has occurred. You can also do it.

Further, as described above, the storage unit 35 of the monitoring device 32 is the image received from the imaging units 13 and 14, the sound collecting unit 12, the depth measuring unit 15, the talking unit 33 of the monitoring device 32, and the like. Information such as voice can be stored. As a result, the diving history of the diver can be memorized, and the situation can be confirmed later. By confirming the situation at the time of the abnormality later, it is more likely that the cause of the abnormality can be investigated. By doing so, it is possible to consider countermeasures for the cause and help prevent recurrence.

Furthermore, since the work scene can be confirmed, it can be used for verification of the work content, explanation at a meeting on the ground, and the like. For example, by using the image of the outward image pickup unit 14, it is possible to explain more clearly what kind of work has been performed, and it is possible to deepen the understanding of related workers, customers, and the like.

The image of the outward image pickup unit 14 allows the scenery around the working position in the water to be seen, and the image of the inward image pickup unit 13 shows the direction in which the diver is looking. Therefore, the images of the inward image pickup unit 13 and the outward image pickup unit 14 can be combined and used for training young workers, for example, what position a skilled diver is looking at during work.

With the information of the depth measuring unit 15, it is possible to quantitatively grasp how the diving person himself performed the diving time, the ascent speed, the timing of the decompression stop, and the like. By doing so, it is possible to know the precautions for the diver to dive safely.

In this way, it is also possible to extract dangerous places and precautions for work in the vicinity of the work place in advance.

A method of rescuing a diver by the diver support system 1 in the present embodiment will be described with reference to FIG. FIG. 6 is a flowchart showing a method of selecting a rescue method for a diver by the diver support system 1 in the present embodiment.

First, a diver dives and works underwater (S10). The worker on the water confirms the work of the diver on the ship on the display unit 34, and communicates with the diver by the telephone unit 33.

Next, if the image displayed on the display unit 34 is disturbed or the communication unit 33 cannot communicate, it is considered that an abnormality has occurred in the diver (S11). The occurrence of the abnormality may be determined by a worker on board. For example, when an electrocardiogram is being measured, if the measured waveform shows a waveform that deviates from a predetermined threshold value, the abnormality is considered to be abnormal. The monitoring device 32 may determine. When it is determined that such an abnormality has occurred, it is determined whether or not the pupil is open based on the image of the inward image pickup unit 13 displayed on the display unit 34 (S12, S13).

When the pupil is open, the rescue of the diver is very urgent, so the first rescue method is selected (S14) and the diver is rescued. If the pupil is not open, a second rescue method is selected (S15) to rescue the diver so that other risks can be eliminated as much as possible. In addition, the current depth of the diver may be combined with information such as whether or not the pupil is open, and the monitoring device 32 may be configured to determine which rescue method should be selected. The above is the selection method of the diver's rescue method by this diver's support system 1.

The present invention is not limited to the exemplified embodiments, and various improvements and design changes can be made without departing from the gist of the present invention.

As described above, according to the present invention, when an abnormality occurs while a diver is working underwater, the worker on the water is provided with useful information for selecting a rescue method for the diver. A diving mask and a diver support system can be provided.
