3 is a flowchart illustrating each step in which the safety management device 100 related to a vessel operates according to an embodiment.

In step S310, the device 100 may obtain user status information from the wearable device 110 worn by the user. The user state information may include information on at least one of the user's blood pressure, fall, heart rate, user location, movement, and body temperature.

In step S320, the device 100 may obtain vessel condition information indicating a situation within the vessel. The ship condition information may include information on at least one of fire, intruder, ship location, floor leak, collision occurrence, speed, direction, and wind strength.

In step S330, the device 100 may determine a problem situation type based on the user status information and the vessel situation information. The type of problem situation may be determined according to whether the problem occurs in the user or the vessel.

In step S340, the device 100 may determine an emergency level indicating the degree of emergency of the user based on the user status information, the vessel situation information, and the problem situation type.

In one embodiment, the device 100 may determine an emergency level range indicating a range for an emergency level based on the type of problem situation. The emergency level range may mean the entire range of emergency levels determined according to the degree of emergency. In an embodiment, an emergency level within an emergency level range may be determined using a situational emergency level determined according to user status information and a vessel weight level determined based on vessel situation information. The situational emergency level is based on whether the heart rate is abnormal, whether the blood pressure is abnormal, whether the body temperature is abnormal, whether the user's location is inside the ship, whether the user's location is outside the ship and the body temperature is below the preset value, and whether there is movement. can be determined by In one embodiment, the device 100 may determine the emergency level by comparing ranges for normal heart rate, normal blood pressure, and normal body temperature pre-stored in a database with acquired user condition information.

The device 100 according to an embodiment includes whether the heart rate is abnormal, whether the blood pressure is abnormal, whether the body temperature is abnormal, whether the user's location is inside the ship, whether the user's location is outside the ship and whether the body temperature is below a predetermined value, and A situation emergency level may be determined based on weights assigned to motions to gradually decrease in order.

For example, heart rate is a factor directly related to a person's life, and if it is outside the normal range of 60 to 100 bpm, it can be judged that there is a high probability of leading to death. there is. In addition, if a person has high blood pressure, there is a possibility of cardiac arrest, and in case of low blood pressure, there is a probability of collapsing. Since it is possible to determine whether or not there is an abnormality in blood pressure, a second high weight can be assigned. In addition, body temperature can appear differently depending on the weather, and in the case of the sea, the temperature is generally low and windy, so the body temperature can be generally measured low, and the body temperature outside the normal range is not simply due to a cold or disease, but on a ship In the case of , when a problem occurs, a change in heart rate or blood pressure occurs first, and a change in body temperature is highly likely to occur later. In addition, in the case of the above-mentioned three factors heart rate, blood pressure, and body temperature, the importance may be higher in that they may be factors that determine the level of emergency according to the user in all situations inside and outside the ship, and when the user's location is outside the ship There is a possibility that the user has fallen into the sea, but since there may be a case where the user monitors ship situation information outside the ship, a high weight of 4 ranks can be assigned to whether the user's location is inside the ship. In addition, if the user's location is outside the ship and the body temperature is below the preset value, it is an element to check if the body temperature drops below the preset value when drowned in the sea. Changes in each of the above factors occur first 5, a high weight may be assigned to whether the user's location is outside the ship and the body temperature is below a predetermined value. In addition, the importance of the user's movement may be low in that whether or not there is movement is likely to include a situation in which the user is resting or not moving depending on the situation, so a high weighted 6th rank is given to whether or not there is movement. can be granted Since the device 100 determines the situation emergency level based on the weights given to each element in the above-described order, efficiency can be improved in that it can determine a more accurate emergency level.

In one embodiment, the vessel weighting level is based on whether a fire occurs, whether a collision occurs, whether a floor leak occurs, the vessel's position is the distance between the user's position, the speed of movement, whether the direction is heading toward the user's position, and wind strength can be determined

According to an embodiment, the device 100 determines whether a fire has occurred, whether a collision has occurred, whether a floor leak has occurred, the distance between the location of the ship, the speed of movement, the direction of movement of the user, and the strength of the wind. It is possible to determine the ship weighting level based on weights assigned to be gradually lowered as .

For example, fire can occur both when a user is on board a ship and when not on board, and in the case of a fire, it can be dangerous to the user's life when the user is on board, and the failure of parts of the ship and the defect in the ship itself ( Since the probability of occurrence is highest, the highest weight may be assigned to whether or not a fire occurs. In addition, when a ship collides, a defect may occur in the ship and a user may be injured, but the collision may have a high probability of occurring during sailing (collision with a rock in the sea, etc.), and depending on the degree of collision, the user's Since there may be differences in the degree of injury, if the degree of collision is not severe, there may not be a large impact, so whether or not a collision occurs can be given a second high weight. In addition, when a floor leak occurs, the ship is filled with water, which may cause a dangerous situation for the user, but it may be slightly lower than the risk caused by fire and collision. can In addition, if the location of the ship and the user's location are more than a preset distance after the user boards the ship, it can be determined that there is a high probability that the user fell into the sea away from the ship. Since the importance is low, the distance between the ship position and the user position can be given a high weight of 4th rank. The speed of progress can be important because it is an element that can obtain information about the time a user can endure when a problem occurs, but it can vary considerably depending on the type of problem, and depending on the situation (weather, temperature, humidity, etc.) ), in that the accuracy may be lowered, and in that the importance may be slightly lower than the above four factors, the progress speed may be given a high weight in the 5th rank. In addition, the direction of travel may also be a factor that can obtain information about the time a user can endure in the event of a problem, but has a great effect in the case of a fire, but has a low effect in the case of a collision or leak on the floor. Therefore, a weight as high as 6 can be assigned to whether the direction of travel is toward the user's location. In addition, the wind strength can have a great influence on the navigation of the ship, but it can be predicted in advance before sailing, so the probability of damage caused by it may be low, and the probability that the wind strength is directly related to human life is rather low In , a weight as high as 7th may be assigned to the wind strength. Since the device 100 determines the ship weight level based on the weights given to each element in the above-described order, efficiency can be improved in that a more accurate emergency level can be determined.

The emergency level according to an embodiment may be determined to correspond to a value obtained by adding the determined situational emergency level and the vessel weight level. In addition, the emergency level may be determined as the maximum level when the sum of the situation emergency level and the ship weight level is greater than or equal to a preset value.

In addition, in determining the emergency level, a higher weight than the vessel weighting level may be assigned to the situation emergency level. Since the situation emergency level is a level connected to the user's life, it can be judged to be more important than the ship weight level, so the situation emergency level has a higher weight than the ship weight level (for example, 1.5 times the ship weight level for the situation emergency level) Determines the emergency level by assigning a weight of ) may be assigned, and the emergency level range may include level 1 to level 5. In this case, the maximum level may mean an emergency level of 5. In addition, in the case of emergency level 1 and emergency level 2, when it is determined that information on the type of problem situation determined by the user device 170 and the external server 120 is transmitted and the problem situation continues to occur after the first time A request for provision of the first number of alert notifications may be made. In addition, when the emergency levels are 3 and 4, information on the type of the determined problem situation can be transmitted to the user device 170 and the external server 120, and if it is determined that the problem situation continues to occur after the second time, You can request to provide 2 alert notifications. In addition, when the emergency level is 5, information on the type of problem situation determined by the user device 170 and the external server 120 can be transmitted, and when it is determined that the problem situation continues to occur after the third time, the third time A request for provision of an alarm notification may be made, and a type of problem situation and provision of an alarm notification may be further requested to another preset ship server. In one embodiment, the first time may be longer than the second time, the second time may be longer than the third time, and the third time may be greater than the second time, and the second time may be greater than the first time. Therefore, there is an effect that prompt response is possible by providing different notifications according to the level of emergency.

According to an embodiment, the device 100 may determine whether the user is boarding a ship, and when it is determined that the user is not boarding the ship, the device 100 transmits information about the type of problem situation that is preferentially determined to the user device 170. and when it is determined that a problem situation continues to occur after a predetermined time, information on the type of problem situation and an emergency rescue request for the vessel may be transmitted to the external server 120. If it is determined that the user has not boarded the ship, the external server 120 may be requested to transmit information on the type of problem situation that has been determined preferentially and to provide an alarm notification, and it is determined that the problem situation continues to occur after a predetermined time. If necessary, an emergency rescue request for the ship and crew may be transmitted to the external server 120 . Therefore, efficiency can be improved in that a prompt response according to the situation may be possible because the object to which the notification message corresponding to the emergency level is provided is determined differently depending on whether the user is boarding the ship or not.

As shown in FIG. 4 , the device 100 obtains human body detection data including information such as the user's body temperature, motion, location, blood pressure, whether or not there has been a fall at sea, and heart rate through the wearable device 110 worn by the user. can do. In addition, vessel detection data including information such as whether there is a fire in the vessel, whether there is an intruder, and the location of the vessel may be obtained from a plurality of sensors. The device 100 may obtain user state information by storing, analyzing, and determining based on the acquired human body sensing data, and may obtain vessel situation information by storing, analyzing, and determining based on the acquired vessel sensing data. . Therefore, the device 100 may provide the analysis result to the user account, and when it is determined that a problem has occurred, the device 100 determines the problem situation type based on the user status information and the ship situation information, and the emergency level determined as described above. A notification message corresponding to may be provided. In addition, the notification message may be provided to at least one of a user account or an external server 120 (maritime police server) according to a situation and an emergency level.

As shown in FIG. 5 , the wearable device 110 may detect the user's pulse, body temperature, movement state, and whether or not a fall has occurred, and may obtain the user's location information and record the movement line. In addition, the result thereof may be transmitted through interworking with the user device 170, and information may be provided through interworking with the device 100. In addition, the device 100 may detect the presence or absence of a fire from a plurality of sensors based on the IoT, detect and monitor the presence of an intruder, and obtain location information.

According to an embodiment, when an emergency occurs by detecting changes in the user's body and determining the user's condition using AI technology, even when the user cannot operate the device, a rescue request signal can be automatically transmitted, improving convenience. It can be. In addition, since it can be used using the application of a general wearable device (smart watch), the inconvenience of having to use a dedicated device can be reduced, and there is an effect of cost reduction because there is no need to purchase equipment separately. In addition, since the ship situation can be monitored using a smart watch or smartphone carried by the user, efficiency can be improved in that the ship situation can be recognized even when the user is far away from the ship, and the user's status information, Since the user determines an emergency level representing the degree of emergency in consideration of both ship situation information and problem situation types and provides a notification message corresponding to the emergency level, it is possible to provide more appropriate notification according to the situation.
