Another example of the monitoring device 100 is shown schematically. An example of the hardware configuration of the computer 1200 that functions as the monitoring device 100 is schematically shown.

Hereinafter, the present invention will be described through embodiments of the invention, but the following embodiments do not limit the inventions that fall within the scope of the claims. Also, not all combinations of features described in the embodiments are essential to the means of solving the invention.

FIG. 1 schematically shows an example of the monitoring device 100. The monitoring device 100 is attached to the diver 20 and has a function of monitoring the respiration of the diver 20. The diver 20 may be a person diving underwater. Although FIG. 1 illustrates a case where the monitoring device 100 is attached to the arm of the diver 20, the monitoring device 100 may be attached to other than the arm of the diver 20.

Normally, the diver 20 takes a safety course in advance to learn that he / she must not hold his / her breathing during diving and must keep breathing at all times, and consciously manages his / her breathing during diving. .. In addition, the diver 20 usually dives with the buddy 30, and when an accident that cannot be dealt with by himself / herself occurs during the dive, the diver either notifies the buddy by a hand signal or the buddy senses the condition and helps. ing.

As mentioned above, although the divers 20 manage their breathing individually, air due to hyperinflation of the lungs after ascent due to carelessness, unconscious breathing stoppage, or insufficient exhaust. May develop embolism and decompression sickness. Therefore, it is desirable to provide a mechanism that can constantly monitor breathing at regular time intervals, detect when breathing is stopped on the spot, and make the person aware of exhaust gas. In addition, gas poisoning (nitrogen narcosis, etc.) or unforeseen circumstances may cause a panic, and the diver 20 may not be able to notify the buddy 30 of the accident, which may lead to an accident. It is desirable to provide a mechanism for notifying the buddy 30.

The monitoring device 100 according to the present embodiment detects a respiratory abnormality of the diver 20 based on the respiratory sound information related to the respiratory sound of the diver 20, and executes a notification process according to the detection. The breath sounds information includes, for example, a predetermined number of breaths per hour. The breath sounds information may include information indicating whether or not the breathing is normal.

The monitoring device 100 is connected to a sound collecting sensor 200 mounted on the chest of the diver 20. Although FIG. 1 shows a situation in which the monitoring device 100 and the sound collecting sensor 200 are connected by wire, the monitoring device 100 and the sound collecting sensor 200 may be wirelessly connected. The monitoring device 100 acquires breathing sound information by receiving sensor data indicating a sound collection result by the sound collection sensor 200 from the sound collection sensor 200 and analyzing the sensor data, for example.

The monitoring device 100 executes a vibration process that vibrates a vibrator device arranged so that the vibration is transmitted to the diver 20 when, for example, an abnormality in the respiration of the diver 20 is detected. As a result, the diver 20 who is unconsciously disturbed or stopped breathing can be made aware of this and take measures such as adjusting the breathing. The monitoring device 100 may be provided with a vibrator device by itself, or may vibrate an external vibrator device.

Further, the monitoring device 100 executes a light emitting process for causing the light emitting unit to emit light when, for example, an abnormality in the respiration of the diver 20 is detected. As a result, the buddy or the like can be made aware that the diver 20 has an abnormality in breathing. The light emitting unit may be, for example, an LED (Light Emitting Diode) light emitting device. The monitoring device 100 may include a light emitting unit by itself, or may cause an external light emitting unit to emit light.

Further, the monitoring device 100 executes, for example, a voice output process for causing the voice output unit to output voice when an abnormality in breathing of the diver 20 is detected. As a result, it is possible to easily convey that an abnormality has occurred in the breathing of the diver 20 not only to the buddy but also to other divers 20 and the like in the vicinity. The audio output unit may be, for example, an underwater speaker. The monitoring device 100 may include an audio output unit by itself, or may have an external audio output unit output audio.

The monitoring device 100 may further detect the type of respiratory abnormality of the diver 20. Types of respiratory abnormalities include, for example, a disordered state of breathing and an apnea state in which breathing is stopped.

The monitoring device 100 records, for example, the number of breaths for each predetermined time, and when the number of breaths changes by a predetermined number of times or more, it determines that the respiratory disorder state. As a predetermined time, an arbitrary time such as 10 seconds or 15 seconds may be set or may be changed. As a predetermined number of times, an arbitrary number of times such as two times and three times may be set, and may be changeable.

Further, for example, the monitoring device 100 determines that the patient is in an apnea state when there is no respiration for a predetermined time. As a predetermined time, an arbitrary time such as 5 seconds or 8 seconds may be set or may be changed.

The monitoring device 100 may execute notification processing according to the type of respiratory abnormality of the diver 20. For example, the monitoring device 100 executes at least one of light emission processing and vibration processing when the respiratory state of the diver 20 is a respiratory disorder state. Further, for example, the monitoring device 100 executes the voice output process when the breathing state of the diver 20 is an apnea state.

For example, the monitoring device 100 starts the light emitting process and the vibration process when the breathing state of the diver 20 becomes a respiratory disorder state, and stops the light emitting process and the vibration process when the diver 20 returns to the normal state, and apnea. When the state is changed, the audio output process may be further started. As a result, when the risk of the state of the diver 20 is low, only the person and the buddy can be notified, and when the risk is high, more people can be notified, depending on the state of the diver 20. Notification processing can be executed.

The monitoring device 100 may execute a display process for displaying on the display unit different notification contents depending on whether the diver 20's breathing state is a respiratory disorder state or an apnea state. For example, when the breathing state of the diver 20 is a respiratory disorder state, the monitoring device 100 displays a notification content prompting the diver to adjust the breathing on the display unit, and when the breathing state of the diver 20 is an apnea state, the monitoring device 100 displays. Display the notification content that encourages you to breathe on the display. This allows the diver 20 to clearly understand what the diver 20 should do. The monitoring device 100 displays the notification content on, for example, a display unit provided by the monitoring device 100. Further, the monitoring device 100 may display the notification content on the display unit of the dive computer 300. The monitoring device 100 and the dive computer 300 may be wirelessly connected or may be wiredly connected.

FIG. 2 schematically shows an example of the functional configuration of the monitoring device 100. The monitoring device 100 includes a storage unit 102, a breath sound information acquisition unit 104, an abnormality detection unit 106, a notification processing execution unit 108, a data transmission unit 110, and a data reception unit 112. It is not always essential that the monitoring device 100 includes all of these.

The storage unit 102 stores various types of information. The storage unit 102 stores, for example, respiration identification data. The respiration identification data may be data for identifying the respiration sound included in the sound output by the sound collection sensor 200.

The respiration identification data may be data that can identify one respiration, and the monitoring device 100 may be able to specify the respiration rate of the diver 20 by using the respiration identification data. Further, the respiration identification data may be data that can identify whether or not the respiration is normal, and the monitoring device 100 uses the respiration identification data to determine whether the respiration of the diver 20 is normal. It may be possible to determine whether or not.

The respiratory identification data may be, for example, a machine learning model in which a large amount of respiratory sound data is learned. The respiration identification data is generated by, for example, an arbitrary device and stored in the storage unit 102 of the monitoring device 100. The device may generate respiratory identification data by any existing generation method.

The device generates respiratory identification data, for example, by collecting a large amount of respiratory sound data and extracting a characteristic amount of one breath. In addition, the device collects a large amount of data on normal breath sounds and uses an algorithm such as VAE (Variational Autoencoder) to perform machine learning that can distinguish between normal breath sounds and abnormal breath sounds. Generate a model. In addition, the device collects a large amount of normal respiratory sound data and abnormal respiratory sound data, and uses an algorithm such as CNN (Convolutional Neural Network) to obtain normal respiratory sounds and abnormalities. Generate a machine learning model that can distinguish between different breath sounds. The monitoring device 100 may generate the respiration identification data.

The storage unit 102 may store the sensor data output by the sound collecting sensor 200. The storage unit 102 stores, for example, the sensor data output by the sound collecting sensor 200 while the diver 20 is diving underwater.

The breath sound information acquisition unit 104 acquires the breath sound information regarding the breath sound of the diver 20 collected by the sound collection sensor 200. The breath sound information acquisition unit 104 generates breath sound information, for example, by analyzing the sensor data output by the sound collection sensor 200. The respiration sound information acquisition unit 104 may generate respiration sound information based on the sensor data output by the sound collection sensor 200 and the respiration identification data stored in the storage unit 102.

The breath sound information acquisition unit 104 may acquire the breath sound information from another device that has analyzed the data output by the sound collection sensor 200. When the sound collecting sensor 200 has a function of outputting the breath sound information, the breath sound information acquisition unit 104 may acquire the breath sound information from the sound collecting sensor 200.

The abnormality detection unit 106 detects a respiratory abnormality of the diver 20 based on the respiratory sound information acquired by the respiratory sound information acquisition unit 104. The abnormality detection unit 106 may detect an abnormality in the respiration of the diver 20 in water. The abnormality detection unit 106 detects a respiratory abnormality of the diver 20 based on the respiratory sound information acquired by the respiratory sound information acquisition unit 104 in water, for example.

The abnormality detection unit 106 may detect a breathing abnormality of the diver 20 based on the number of breaths included in the breath sound information. For example, the abnormality detection unit 106 determines that the diver 20's breathing is abnormal when the number of breaths within a predetermined time is equal to or less than the predetermined number of breaths. The abnormality detection unit 106 may determine that the diver 20's breathing is abnormal when there is no breathing within a predetermined time. Further, for example, the abnormality detection unit 106 determines that the diver 20's breathing is abnormal when the breathing rate for each predetermined time changes by a predetermined number of times or more.

The abnormality detection unit 106 may further detect the type of respiratory abnormality of the diver 20. Types of abnormalities include, for example, respiratory disturbances and apnea. The abnormality detection unit 106 determines, for example, that the breathing state of the diver 20 is a respiratory disorder state when the breathing rate for each predetermined time changes by a predetermined number of times or more, and determines in advance. If there is no breathing within the specified time, it is determined that the patient is in an apneic state. As a specific example, when the number of breaths every 10 seconds changes three or more times in succession, the abnormality detection unit 106 determines that the breathing state of the diver 20 is a respiratory disorder state, and there is no breathing. When the state continues for 5 seconds, the breathing state of the diver 20 is determined to be an apnea state.

The abnormality detection unit 106 may detect an abnormality in the respiration of the diver 20 on the ground. The abnormality detection unit 106 detects, for example, a respiratory abnormality of the diver 20 based on the respiratory sound information acquired by the respiratory sound information acquisition unit 104 before the diver 20 enters the water.

The notification processing execution unit 108 executes the notification processing in response to the detection of the respiratory abnormality of the diver 20 by the abnormality detection unit 106. The notification processing execution unit 108 may execute the notification processing in response to the detection of the respiratory abnormality of the diver 20 in the water. The notification processing execution unit 108 may execute the vibration processing as the notification processing. The notification processing execution unit 108 may execute the light emission processing as the notification processing. The notification processing execution unit 108 may execute the voice output processing as the notification processing. The notification processing execution unit 108 may execute the display processing as the notification processing.

The notification processing execution unit 108 may execute notification processing according to the type of respiratory abnormality of the diver 20. For example, when the breathing state of the diver 20 is a respiratory disorder state, the notification processing execution unit 108 executes at least one of light emission processing and vibration processing as the notification processing. When the breathing state of the diver 20 is an apnea state, the notification processing execution unit 108 may execute the voice output processing as the notification processing. When the state of the sphere of the diver 20 is an apnea state, the notification processing execution unit 108 may execute light emission processing, vibration processing, and voice output processing.

The notification processing execution unit 108 started at least one of the light emission processing and the vibration processing in response to the breathing state of the diver 20 becoming a respiratory disorder state, and the breathing state of the diver 20 returned to the normal state. In that case, the light emission processing and the vibration processing during execution may be stopped, and when the respiratory state of the diver 20 transitions to the apnea state, the audio output processing may be further started.

As the notification process, the notification process execution unit 108 may execute a display process for displaying different notification contents depending on whether the diver 20's breathing state is a respiratory disorder state or an apnea state. For example, when the breathing state of the diver 20 is a respiratory disorder state, the notification processing execution unit 108 causes the display unit to display the notification content prompting to adjust the breathing, and the breathing state of the diver 20 is an apnea state. In this case, the content of the notification prompting the person to breathe is displayed on the display unit. The notification processing execution unit 108 displays the notification content on, for example, a display unit included in the monitoring device 100. Further, the notification processing execution unit 108 may display the notification content on the display unit of the dive computer 300.

The notification processing execution unit 108 may execute the notification processing for notifying the warning for the entry of water in response to the detection of the abnormal breathing of the diver 20 by the abnormality detection unit 106 before the entry of the diver 20 into the water. Respiratory abnormalities, such as a cold and swollen throat, can be fatal in diving, even if they are mild. On the other hand, by issuing a warning to the diver 20 in response to the detection of a breathing abnormality before entering the water, it is possible to prevent the occurrence of an accident in the water.

The notification processing execution unit 108 causes, for example, the vibrator device to execute a vibration indicating a warning. The notification processing execution unit 108 causes, for example, the light emitting unit to emit light of a color indicating a warning. The notification processing execution unit 108 causes, for example, the audio output unit to output a warning sound. The notification processing execution unit 108 causes, for example, the voice output unit to output a message urging the water entry to be stopped by voice. The notification processing execution unit 108 causes, for example, display and output a message urging the display unit to stop entering water.

The data transmission unit 110 transmits the sensor data stored in the storage unit 102 to the external device. For example, the data transmission unit 110 transmits the sensor data output by the sound collecting sensor 200 while the diver 20 is diving and stored in the storage unit 102 to an external device after the diving of the diver 20 is completed. .. The external device may be any device such as a mobile communication terminal owned by the diver 20 or a server on the Internet.

The data receiving unit 112 receives the respiration identification data dedicated to the diver 20 generated by the external device based on the sensor data from the external device to which the data transmitting unit 110 has transmitted the sensor data. The data receiving unit 112 stores the received respiration identification data in the storage unit 102. The data receiving unit 112 may update the respiration identification data stored in the storage unit 102 with the received respiration identification data. As described above, by using the respiration identification data dedicated to the diver 20 generated based on the sensor data while the diver 20 is diving, the respiration identification accuracy of the diver 20 can be improved. In addition, it is possible to realize anomaly detection of the respiration of the diver 20 in consideration of the respiration characteristics of the diver 20. For example, when a diver 20 tends to stop breathing for a short time even though it is in a normal state, the breathing stop for the time corresponding to the short time is not determined to be abnormal. False detection of respiratory status can be suppressed.

FIG. 3 schematically shows an example of the hardware configuration of the monitoring system 10. The monitoring system 10 illustrated in FIG. 3 includes a sound collecting sensor 200, a digital signalizing device 410, a breathing sound analysis device 420, a breathing frequency recording device 430, a time stamping device 440, and a monitoring device 100, which are attached to the skin of the diver 20. It includes an LED light emitting device 450, a vibration device 460, and an alarm sound generator 470. The sound collecting sensor 200 illustrated in FIG. 3 outputs the collected sound as an analog signal.

The digital signalizing device 410 converts the analog signal output by the sound collecting sensor 200 into a digital signal. The breath sound analyzer 420 analyzes the digital signal output from the digital signalizing device 410. The breath sound analyzer 420 may output the number of breaths within a predetermined time.

The respiration rate recording device 430 records the respiration rate output by the respiration sound analyzer 420. The time stamp device 440 stamps the number of breaths output by the breath sound analyzer 420. The monitoring device 100 acquires respiratory rate information from the respiratory rate recording device 430 and the time stamping device 440. The monitoring device 100 detects a respiratory abnormality of the diver 20 based on the respiratory rate information. The monitoring device 100 executes a light emitting process for causing the LED light emitting device 450 to emit light, a vibration process for vibrating the vibration device 460, or causes the alarm sound generator 470 to emit light in response to the detection of the breathing abnormality of the diver 20. Executes voice output processing that generates an alarm sound. The alarm sound generator 470 has, for example, an underwater speaker, and generates an alarm sound at a volume reaching a radius of 50 m from the underwater speaker.

FIG. 4 schematically shows an example of the processing flow by the monitoring device 100. Here, a state in which monitoring by the monitoring device 100 is started after the diver 20 enters the water will be described as a start state.

In step 102 (the step may be abbreviated as S) 102, it is determined whether or not the abnormality detection unit 106 has detected the disorder of breathing of the diver 20. If a respiratory disorder is detected, the process proceeds to S104. In S104, the notification processing execution unit 108 executes light emission processing and vibration processing as notification processing.

In S106, the abnormality detection unit 106 determines whether or not the respiration of the diver 20 has been normalized. If it is determined that it has been normalized, the process proceeds to S108, and if it is determined that it has not been normalized, the process proceeds to S110. In S108, the notification processing execution unit 108 stops the notification processing.

In S110, the abnormality detection unit 106 determines whether or not the apnea of the diver 20 has been detected. If apnea is not detected, the process proceeds to S112, and if apnea is detected, the process proceeds to S114. In S112, the abnormality detection unit 106 determines whether or not the respiration of the diver 20 has been normalized. If it is determined that it has been normalized, the process proceeds to S108, and if it is determined that it has not been normalized, the process returns to S110.

In S114, the notification processing execution unit 108 adds an audio output as the notification processing. In S116, the abnormality detection unit 106 determines whether or not the respiration of the diver 20 has been normalized. If it is determined that the normalization has occurred, the process proceeds to S108.

In S108, after the notification processing execution unit 108 stops the notification processing, the process returns to S102. The process shown in FIG. 4 may be continued while the diver 20 is in the water and may be stopped after the diver 20 has moved from the water to the ground.

FIG. 5 schematically shows another example of the monitoring device 100. In addition to the sound collecting sensor 200, a chest circumference sensor 500 is connected to the monitoring device 100 shown in FIG. The chest circumference sensor 500 measures the chest circumference of the diver 20 and transmits chest circumference information indicating the chest circumference of the diver 20 to the monitoring device 100. Although FIG. 5 shows a situation in which the monitoring device 100 and the chest circumference sensor 500 are connected by wire, the monitoring device 100 and the chest circumference sensor 500 may be wirelessly connected.

The monitoring device 100 may include a chest circumference information acquisition unit that acquires the chest circumference information of the diver 20 output by the chest circumference sensor 500. In the notification processing execution unit 108 of the monitoring device 100, the chest circumference indicated by the chest circumference information before the diver 20 rises from the water to the water is set from a predetermined threshold value with respect to the chest circumference indicated by the chest circumference information before the diver 20 enters the water. If it is long, perform notification processing. If the diver 20's chest circumference in water is longer than before entering the water, the lungs may be dilated, and if they ascend as they are, they may cause lung overdilation. On the other hand, by executing the notification process by the notification processing execution unit 108, it is possible to calm the breathing before ascending and to urge the diver to ascend after sufficiently exhausting the air, thereby increasing the safety of the diver 20. Can be done.

The notification processing execution unit 108 may execute at least one of vibration processing, light emission processing, audio output processing, and display processing as the notification processing. In addition, the notification processing execution unit 108 may display the notification content that calms the breathing on the display unit before ascending when the display processing is executed.
