Description

Technical Field [0001] The present invention relates to an intelligent navigation system for a maritime victim,

More particularly, the present invention relates to a system for responding systematically to disaster management by integrating ICT technology in the disaster safety field in the marine environment, In order to secure the golden time for the construction of the victims of the city, we will provide a system that can confirm the location of the victim in real time based on Buoy type smart point. Low-power long distance communications (LPWA), distress location and information collection technology, distress signal propagation technology, distress information transmission / sharing technology for distress monitoring and rescue support are included.

With the increase in income and the establishment of a five-day workweek, the population enjoying water leisure sports and marine ecological experiences such as rafting, windsurfing, kayaking, etc. is soaring, and the possibility and frequency of marine accidents are rapidly increasing. There is a growing need for a system that can systematically respond to accidents.

However, in addition to the large-scale catastrophic accidents in the marine area, such as the accident of sinking in Lake Seokho (April 14), the marine camp in Taean in Chungcheong Province (March 13, 2007), more than 20 deaths occurred in beaches every year and more than 50 accidents occurred in fishing boats . In 2012, the number of marine accidents has increased sharply since 2009. According to marine vessel accident data among government 3.0 information disclosure data, 2,610 marine vessel accidents were reported in 2016, of which 874 were accidental deaths, sinking and stranding. Given this reality, it can be seen that the response-oriented disaster response system has not been established yet. Therefore, there is a need to reconstruct the disaster response monitoring system at the ocean centered on the demanders.

According to the Australian Maritime Safety Agency (MAST) data, if you fall below 10 ° C, you may lose consciousness within an hour and survive within 3 hours. Therefore, in case of an accident caused by sinking or stranding, a quick rescue system should be provided for the victim to minimize the casualties caused by marine accidents. However, ship - based marine disaster management system is actively invested and developed, but it is relatively weak to construct safety rescue system for rescue operations against human distress. Therefore, there is a need to convert existing management and management systems for marine disasters into preemptive and preventive systems. To this end, the transition to an intelligent marine safety disaster management system using various IT devices should be presented as an alternative do.

In particular, it is necessary to monitor marine distress early and to prepare a monitoring system to support the emergency response and structure of the disaster site by transmitting and sharing disaster information to disaster response organizations. In the marine distress site, It is urgent to construct a monitoring system that can collect information on the location of the disaster and monitor the distress situation and transmit the disaster information to the ground monitoring system through the disaster communication network.

Conventional technologies related to distress information collection technology include life jackets using RFiD technology and life jackets using satellite communication technology. However, in the case of life jackets using RFiD technology, It is virtually impossible to find a demanding person in the market, and it is proved to be a technology that is not feasible, and there is a limitation even in the battery holding time. On the other hand, life jacket using satellite communication technology has good communication coverage, but battery consumption time due to power consumption due to communication equipment operation is extremely short. In addition to excessive communication maintenance cost, weight and size can not be ignored. It has been hard to apply. In addition, GPS technology has been suggested as a technique for grasping the location information of a victim. In addition, since there is a need to transmit location information, there is a lot of realistic problems in making the marine disaster a response-oriented response system, such as being blocked by the wall of the information gathering technology described above.

In order to solve the above-mentioned problems, in a floating smart point-based marine constursion signaling control system according to the present invention, low power long distance communication, GPS based position signal reception, gyro sensor, etc. are applied to acquire position and activity information of a wearer A smart device that receives information of the lifeline device and transmits information to the distress management server of the land and marine site structure line, and a control server that monitors the distress situation of the victim from the land and the vessel Which is within 10km to overcome marine constraints such as waves, flooding, fog, storm, wind, and distance considering the characteristic of marine accident where communication environment is not smooth. To collect and store the location information and activity information of the victim from the buddy smart point In addition, it is possible to send the information to the control server located at a long distance in the sub-type smart point, so that the information transmitted from the life device of the victim can be transmitted to the rescue helicopter and the rescue helicopter when the rescue helicopter or the rescue helicopter approaches the distressed area. .

In order to achieve the above object, the present invention provides a marine destructive rescue signal control system based on a floating smart point based on the present invention, which comprises a life device, a smart point and a control server, Wherein the disturbance detection sensor, the position measuring device, the gyro sensor, and the communication device, when the distress sensor or the distresser is manually operated to switch to the distress occurrence mode, The first distress information including the distress activity information measured by the sensor, the first identification code that is identification information thereof, and the distress signal is transmitted to the smart point through the communication device at predetermined time intervals; Wherein the smart point is a floating type that can float on water and includes distress occurrence determination means, position measurement means, storage means, first communication means, and second communication means, wherein the first communication means is connected to the communication device of the life device Wherein the first distress information collecting unit collects the first distress information through the first communicating unit and stores the first distress information in the storing unit when the distress occurrence determining unit determines that a distress accident has occurred, The second distress information including the second identification code and the distress signal to the control server through the second communication means at a predetermined time interval; Wherein the control server is located on the land or on a ship and collects and analyzes the second distress information transmitted by the smart point to monitor the location and status of the distress person; And the first identification code and the second identification code include a self-identification code.

In addition to the above-described features, the life device may include only the first identification code and the distress signal in the first distress information without activating the position measuring device and the gyro sensor when the mode is switched to the distress accident occurrence mode The smart point transmits the first distress information through the first communication means at a predetermined time interval when receiving the first distress information including only the first identification code and the distress signal from the life device, Wherein the lifesaver requests the location information and the gyro sensor to send additional information to the life device, and the life device activates the position measurement device and the gyro sensor only when receiving a request signal for the additional information from the smart point, The distress activity information is measured and included in the first distress information, Wherein the connection attempt interval for the Access Point is widened when the communication device continues to be disconnected from the Access Point for a predetermined period of time. Do.

In addition, the portable smart-point rescue signal control system according to the present invention may be configured such that, when receiving the second distress information from the smart point, the control server transmits the second distress information to the self- Wherein the smart point identifies the distressed vessel with the identification code and requests detailed information about the smart point that transmitted the second distress information at predetermined time intervals, The second distress information is further included in the distress information and is transmitted to the control server. If the detailed information is not received until a predetermined time elapses from the time of transmitting the second distress information, the second distress information is transmitted And the time interval for performing the operation is increased.

In addition, the portable smart-point rescue signal control system based on the floating point type smart point according to the present invention further includes a gateway for the first communication means of the smart point, and the smart point is connected to the life- Wherein the SmartPort further comprises a third communication means, and the third communication means further comprises a second communication means for communicating with the third communication means, wherein the control server is connected to the life device through the gateway to perform control and information collection, And transmitting the second distress information including the first distress information through the third communication means when receiving the information request signal from the rescue line or the rescue helicopter through the third communication means.

In addition, according to the present invention, in addition to the above-described features, the smart point may be configured such that the first distress information is transmitted through the first communication means in a state where no distress accident occurs When the first distress information includes the self-ship identification code, it is determined that some of the passengers are distressed, and when the first distress information does not include the self-identification code, And the first distress information reception result, together with the determination result, is transmitted to the management server of the self-ship or the control server through the second communication means.

Further, in addition to the above-mentioned characteristics, the smart point requests status information to the life device at predetermined time intervals through the first communication means when a distress accident has not occurred, and the life device, When the status information is requested, the smart point transmits its own status information including the first identification code to the smart point through the communication device, and when receiving the status information, And transmits the report to the management server or the control server through the second communication means.

In addition, since the first communication means of the smart point can serve as a gateway to the life devices, it is possible to exchange information directly between the control server and the life device, and remote control of the life device with the control server is also possible.

In addition, since the communication means of the life device is implemented through the object internet network using low power, it is possible not only to transmit the status information of the life device through the smart point for a long time in the event of a marine disaster, And the detailed information is provided when necessary. Therefore, it is possible to use the battery of the life device or the smart point for a maximum of a long time.

In addition, if the communication between the life device and the smart point is not performed properly, that is, if the life device is far away from the smart point due to the current, etc., the connection of the smart point to the AP becomes impossible. In this case, If the AP connection is impossible for a certain period of time, the AP connection attempt interval is lengthened, thereby minimizing the battery consumption due to the AP connection attempt. In addition, even if the smart point is not smoothly communicating with the control server, the second distress information transmission interval is lengthened to minimize the battery consumption of the smart point.

Hereinafter, the present invention will be described with reference to the drawings. First, FIG. 1 is a conceptual diagram of an entire system of a marine victim rescue signal control system based on a negative smart point according to the present invention, and FIG. 2 is a conceptual diagram of operations when a marine accident occurs. As shown in FIG. 1 and FIG. 2, the present invention provides a low power wide area (LPWA) object in a distress accident center centered on a floating smart point which can float on the sea when a ship is thrown during a distress accident Thereby forming an Internet (IoT) network. Life devices such as life jackets, life buoys, and lifesaving boats are connected to access points and gateways of sub-type smart points through the Internet (IoT) network formed by the attached smart points, It is preferable that the sub-type smart point which provides the distress information such as the activity information and receives the distress information is configured to exchange distress information through the high-speed maritime wireless communication network with respect to the monitoring server located at the remote site, Accordingly, it is desirable that the secondary smart-point include at least two communication networks, that is, the object Internet network and the ultra-high-speed wireless communication network.

LPWA, or low-power long-distance communication technology, is one of the technologies used in the field of Internet (IoT), and it has emerged due to different needs from conventional short-range wireless communication and general mobile communication. Cost, stable coverage, large-scale accessibility, and so on. A typical IoT can provide services by using short-range wireless communication such as Bluetooth and Wi-Fi. However, in order to expand the range of IoT services, we had to overcome the shortcoming of short-range wireless communication. Communication chip prices should not be as high as ordinary mobile communication technologies such as LTE. Since charging is difficult, the power consumption must be low. Specific requirements for LPWA implementation include a 10-year battery life and less than $ 5 per device.

On the other hand, it is desirable that the lifespeed device or the smart point can grasp its own position information by itself. For this purpose, it is preferable to use the GPS position measuring means. It is further preferable that the smart point includes a third communication means such as Wifi or VHF communication means so that the smart point can communicate with a ship approaching the structure or a ship or a rescue helicopter passing through a nearby sea. Smart Point and Life Devices are devices that are always mounted on the ship. When the ship is at berth or when it is in normal operation, the smart point and life device communication network is activated in the ship and it is connected to the in-ship communication network. It is desirable to automatically switch to the distress occurrence mode so that the smart point is automatically thrown into the sea when a marine accident such as stranding of a ship occurs.

FIG. 3 is a block diagram of a marine destructive rescue signal control system based on a negative smart point according to the present invention. As shown in FIG. 3, the portable smart-point rescue signal control system according to the present invention may include a life device 100, a smart point 200, and a control server 300. Here, the life device 100 refers to a personal life saving equipment such as a life jacket or a life boat, and in some cases, a lifeboat may also be applicable. The life device preferably includes a distress sensor 110, a position measuring device 120, a gyro sensor 130, and a communication device 140. If necessary, It is also possible to further include a vital sensor (not shown).

The distress detection sensor 110 of the life device 100 can detect that the life device 100 is in the sea, that is, for example, when a passenger wearing a life jacket is in a sea or a lifeboat is placed on the sea A sensor capable of sensing the state of the sensor, etc., can be sensed by various known methods. For example, a pressure sensor may be used to measure the pressure of a submerged portion, or air pressure may be detected if the life jacket is inflated. Also, it is possible to use a method of detecting the distress state by using the motion state of the life device 100 such as a gyro sensor or a vibration sensor, or by various other methods such as rapid position and speed change detection by a gravity sensor or an acceleration sensor. In addition to detecting the distress state by the distress sensor 110, the life device 100 may further include a mode change switch (not shown) capable of switching to a distress occurrence mode by manual operation of the distress person himself / herself .

Meanwhile, the position measuring device 120 may be a device for collecting position information of the life device 100 by receiving a GPS signal as a position information collecting device using GPS. In general, The collecting device can accurately measure the position where it is located with an error within 10m. The gyro sensor 130 is a sensor for collecting activity information of a victim. It is also desirable to include an acceleration sensor in a 9-axis gyro sensor for collecting detailed activity information. The gyro sensor 130 can measure information on the motion information and the posture of the victim, and can determine whether the victim is alive or has a lot of movement, which is an important means for grasping the condition of the victim do. In addition, when the vital sensor is further included, the vital sign of the victim, that is, the body temperature or the pulse, can be measured, thereby providing more detailed information on the survivor's survival.

The communication device 140 is a means for connecting the life device 100 to the smart point 200 through a first communication network 400, which is an object Internet network formed by the smart point 200. The communication device 140 can access the object Internet through the low power long distance communication (LPWA) as described above. FIG. 4 is a diagram illustrating the IoT communication configuration of the life device 100 used in the floating-point smart point-based smartphone system according to the present invention. As shown in FIG. 4, the life device 100 includes the above- In addition, it is preferable that an MCU, which is a control means for controlling the above-mentioned configurations, is included, and an antenna for LPWA communication and an antenna for GPS communication are included, respectively. In addition, it is desirable to use the built-in battery as a power source for operating them. It should be possible to use at least one year in a sleep mode at the time of mooring or normal operation, and at least 48 hours or more in case of a distress accident.

On the other hand, the smart point 200 is a buoyant type that can float on the water, is fixed at a predetermined place in the ship during mooring or normal voyage, and charges the built-in battery by using a charging means by an external power source , It is preferable to throw it on the sea automatically or manually when an emergency situation such as a distress accident occurs. 3, the smart point 200 includes a distress occurrence determination unit 210, a position measurement unit 220, a storage unit 230, a first communication unit 240, and a second communication unit 250, It is also possible to include the third communication means 260 in some cases.

The distress occurrence determination means 210 is a means for automatically detecting when the smart point 200 is in the sea, that is, when an emergency situation such as a distress accident occurs, It is possible to accurately determine the occurrence of distress by various methods. For example, there may be a sudden momentum detection by an acceleration sensor, a pressure increase detection in a submerged part by a pressure sensor, and a vibration detection by a vibration sensor. In this case, If you do it, you will be able to detect it correctly, because it will not be charged if it is thrown into the sea. That is, whether or not the state of charge is an important determining means for determining whether the ship is in a normal operating state or a distressed state. In the case where the smart point 200 is manually thrown into the sea, it is also possible that the thrower or the like manually switches to a distress occurrence state and thrown.

It is preferable that the position measuring means 220 is a position information collecting device using GPS in the same manner as the position measuring device 120 of the life device 100 described above. The smart point 200 preferably includes the storage means 230. The storage means 230 stores the first distress information transmitted from the life device 100 or the first distress information transmitted from the location measurement means 220, And the stored location information may be important information for locating the trajectory of the lifestyle device 100 or the smart point 200 drifting due to currents or the like. The storage means 230 is preferably a storage means formed of a semiconductor such as a flash memory in consideration of weight, power consumption, and the like, but may be another storage means such as a HDD, depending on the case.

The first communication unit 240 forms an LPWA Internet in the vicinity of the smart point 200 and serves as an access point to which the life devices 100 can access, It is also desirable to be able to serve as a gateway. Therefore, the control server 300 can directly collect information from the life devices 100 through the LPWA gateway or directly control the sensors included in the life devices 100. [ FIG. 5 is a diagram illustrating a case where the first communication unit 240 serves as an LPWA gateway for the life devices 100. As shown in FIG. 5, the control server 300 transmits the LPWA gateway The LPWA gateway can collect information directly from the life device 100 or send commands directly to the life device 100 through the LPWA gateway 300. In this case, Lt; / RTI >

The second communication means 250 is a means by which the smart point 200 can communicate with the control server 300. 3, it is preferable that the smart point 200 is connected to the control server 300 through the second communication network 500. The second communication network 500 is a high-speed maritime wireless communication network, The second communication means 250 may be designed and installed as a mobile communication terminal module capable of connecting to an LTE-M network for a wireless backhaul, which is a high-speed maritime wireless communication network. In other words, the LTE-M module based on e-Navigation, which can secure most coverage in the domestic area, is used to transmit data of disaster information to the land base station. However, the frequency band of the LTE network is used, It is preferable that the coverage can reach the place where the control server is located.

FIG. 6 is a diagram illustrating the IoT communication and the super high-speed wireless communication of the smart point 200 used in the immobilizable smart point-based maritime distress signaling system according to the present invention. As shown in FIG. 6, the smart point 200 may include a third communication unit 260 using a third communication network 600 such as a WiFi module and a VHF channel in addition to the above-described configurations. The communication means 260 is a channel forming means for communicating with a rescue boat or a structural helicopter or the like approaching for a ship or a structure passing over a nearby sea. The communicating means 260 is a means for propagating a distress signal in real time through a VHF channel, It is desirable to be able to transmit and receive data in real time via WiFi communication.

Meanwhile, FIG. 7 is a flowchart showing an operation process in a marine catastrophic rescue signal control system based on a negative smart point based on the present invention. Hereinafter, operation processes of the life device 100, the smart point 200, and the control server 300 in the event of a marine disaster will be described with reference to FIG.

As shown in FIG. 7, it is preferable that the lifetime device 100 always maintains a state connected to the smart point 200 regardless of whether a distress occurs or not (step s101). Accordingly, the communication device 140 for connection to the smart point maintains a minimum communication state with the smart point 200, and the position measurement device 120 And the gyro sensor 130 are preferably set to the sleep mode. When the distress accident occurs, the life device 100 is changed to the distress occurrence mode by the distress sensor 110 (step s102), and the smart point 200 is also determined by the distress occurrence determination means 110 It is determined that a distress has occurred (Step s201). Therefore, the life device 100 may transmit the first distress information including the self-identification code, the self identification code, and the distress signal to the smart point 200 through the communication device 140 and the first communication network . In this case, the life device 100 operates the position measuring device 120 and the gyro sensor 130 so that the first distress information and the distress position information measured by the position measuring device 120 and the gyro sensor The position measurement device 120 and the gyro sensor 130 may be stopped before the smart point 200 receives a request for additional information from the smart point 200, It is more preferable to minimize the consumption of the battery.

Meanwhile, in step s201, the smart point 200 determines that the distress occurrence has been detected by the distress occurrence determination unit 110. The smart point 200 determines its own location information, the self-identification code, The second distress information including the code and the distress signal is transmitted to the control server 300 through the second communication means 250 and the second communication network 500 in operation s202, Receives the first distress information transmitted from the first distress information through the first communication network 400 and the first communication means 230 and stores the first distress information in the storage means 230 in operation s203, If the victim location information or the victim activity information is not included, it is preferable that the smart point is requested to request additional information (Step s204).

In step s204, the life device 100 receiving the additional information from the smart point 200 operates the position measuring device 120 and the gyro sensor 130 to measure the distress location information and the distress activity information (Step s104), the first distress information includes the distress information measured by the position measuring apparatus 120 and the distress information measured by the gyro sensor 130, It is preferable to transmit the data through the first communication network 400 (Step s105). In step s105, the smart point 200 receives the first distress information including the distress location information and the distress activity information from the life device 100. The smart point 200 transmits the received first distress information to the storage unit 230, (Step s205).

Meanwhile, in step s202, the control server 300, which has received the second distress information including the location information from the smart point 200, uses the self-identification code included in the second distress information (Step s301). If the first distress information is not included in the second distress information, the smart-point manager 200 identifies the distressed vessel that has sent the second distress information, It is preferable to request detailed information including the first distress information (Step s302). Of course, when the smart point 200 transmits the second distress information, it is also possible to transmit the first distress information from the beginning. However, since the first distress information can be a considerable amount of information depending on the number of the victims, it is necessary to quickly spread the distress situation, and since the smart point 200 also uses a battery, it is necessary to save battery consumption as much as possible. It is preferable that only the own location information and the self-ship identification code are included in the second distress information. Thus, in the floating-type smart-point-based marine destructive rescue signal control system according to the present invention, distress information can be rapidly propagated and the battery use time of the smart point 200 can be maximized.

When the smart point 100 receives a request for the detailed information from the control server 300 in step s206, the control server 300 includes the first distress information in the second distress information, (Step s207). The control server 300 can grasp a specific number of the victims by using the first distress information included in the second distress information, and identify the detailed position and state of the victim (Step s303).

Meanwhile, in step s206, the smart point 200 determines whether the detailed information is requested from the control server 300. If the detailed information is not requested (step s206) It is preferable that the second distress information transmission interval is extended in step s210 if a predetermined time has elapsed since the second distress information was transmitted in step s209. The reason for doing this is that the rescue vessel or the land base station is too far away to be located on the ultra high-speed maritime wireless communication network, i.e., the second communication network, and there may be a temporary or long-term communication failure due to various problems such as weather or equipment failure. , The control server 300 can not request the detailed information because it does not receive the second distress information, and the smart point 200 continues to receive the detailed information through the control server 300 , The disturbance signal is not transmitted to the control server 300 and the battery of the smart point 200 is consumed quickly. Therefore, it is desirable to increase the transmission interval because battery consumption should be saved because it is the disturbance condition which is a situation where it is necessary to endure a long time as long as possible. If the detailed information is requested after the second distress information transmission interval is enlarged, it is also possible to shorten the time again. It is also possible to maintain or enlarge the interval according to the control of the control server 300 . That is, when it is determined that the rescue ship or the like will take a long time to approach, the control server 300 preferably controls the smart point 200 or sends a signal to enlarge the second distress information transmission interval. In this context, it is preferable that the control server 300 controls the interval at which the first distress information is transmitted from the life device 100 or the operation of the position measuring device 120 or the gyro sensor 130. That is, if it is determined that a long time will be required to access the rescue vessel due to weather or the like, the interval for transmitting the first distress information may be enlarged in the life device 100 for extension of battery life, It is preferable that the measuring apparatus 120 or the gyro sensor 130 is switched to the sleep mode as much as possible.

On the other hand, when transmitting an information request signal to the smart point 200 through the third communication network and the third communication means from a ship, a helicopter, or a ship passing near sea for approaching the structure or the like (S701 (Step s208). In the case of a ship which requested information, the distress information is used to identify the premature vessel and the victim, (Step s702).

FIG. 8 is a flowchart illustrating a retry process when lifepoint 100 is disconnected from an AP of smart point 200 in a floating smart point-based signaling system for marine destructive rescue according to the present invention. The life device 100 is a device for generating a distress signal from a victim. In order for the survivor to be structured smoothly, the life device 100 must continuously generate a distress signal from the victim until the distress vessel arrives. However, in a situation where a rescue vessel or the like may arrive late due to the weather or the like, communication may not be smoothly performed immediately after a distress occurs. In this case, when the life device 100 repeatedly attempts communication The built-in battery is consumed early, which increases the likelihood that communication will be lost before the location of the distress can be determined. Accordingly, in the portable smart-point rescue signaling system according to the present invention, when the life device 100 tries to connect to the smart point 200 and the connection is unsuccessful, the connection attempt interval is widened, .

As shown in FIG. 8, it is preferable that the lifespeed device 100 is in a state of being connected to the AP of the smart point 200 when the ship is navigating normally, (Step s101). However, after the life device 100 enters the distress generation mode (step s102) due to the occurrence of a distress accident, after a certain period of time, the smart device 200 and the life device 100 The distance may be outside the reach of the LPWA network, or there may be a temporary or long-term communication failure due to weather or the like. In this case, the life device 100 is disconnected from the AP of the smart point 200 (step s111), and periodically attempts connection (step s112) The built-in battery of the life device 100 is consumed excessively quickly. Accordingly, it is determined whether a predetermined time has elapsed in the disconnected state of the AP (step s113). If the predetermined time has elapsed, the connection attempt interval for the AP is increased to attempt connection (step s115) It is desirable to save.

Meanwhile, FIG. 9 is a flowchart showing the process of monitoring a victim in daily life in a marine victim rescue signal control system based on a negative smart point according to the present invention. It is preferable that the smart point 200 according to the present invention always operates the first communication means 240 even when a distress accident does not occur. When the first distress information is received via the first communication means 240 in step S231, the ship is not distressed, and the occupant of his / her own passenger wearing the life device 100 May be the first distress information if some of them are distressed, or the first distress information that the other passengers of the other ship are distressed and sent from them. Accordingly, if the first distress information is received in step s231, the smart point 200 determines whether the self-identification code exists in the first distress information (step s232) It is determined that some of the passengers of the self-ship are distressed in the presence of the self-identification code (step s233), and the fact that the distress accident has occurred is reported to the control server 300 or the management server 800 of the self- It is also possible to notify the control server 300 and the management server 800 simultaneously (step s234).

If the self-identification code does not exist in the first distress information, it is determined that it is a distress accident for a passenger of another ship (step s235). The control server 300 is notified of the occurrence of the distress accident, It is also preferable to notify the management server 800 of the ship or the like. It is also possible to notify the control server 300 and the management server 800 simultaneously (step s236). Thus, according to the present invention, there is provided an advantage and advantage of monitoring a part of a passenger who is caused by a fall or the like in a ship in a normal operation, or even a distress accident of another ship.

And FIG. 10 is a flowchart illustrating a process of checking a lifetime device at a normal time in a submarine smart point-based marine convoy rescue signal control system according to the present invention. As described above, it is preferable that the smart point 200 according to the present invention always keeps the first communication means 240 in a state in which no distress accident has occurred. In this way, according to the present invention, The smart point 200 can check the status of the lifetime devices via the first communication means 240. [ 10, the smart point 200 requests status information about the lifespeed devices 100 through the first communication network 400 after a predetermined time has elapsed (step s241) (step s242: ), The life devices 100 that have requested the status information check various sensors and devices included therein and transmit status information including the check result and the identification code thereof to the smart point 200 (Step s141). Upon receiving the status information from each of the life devices 100, the smart point 200 makes an 'on-board life device status report' including the communication status and the check result for each life device 100 step S243), and the created report is transmitted to the control server and / or the management server 800. [ As described above, according to the present invention, the smart point system 200 periodically and automatically inspects the life devices 100 and receives the results Therefore, it is possible to provide information that can maintain the state of the life device 100 in the best state, and it is possible to efficiently cope with the occurrence of a marine disaster accident without any trouble. In addition, since the smart point 200 automatically performs such a check, the system can be operated at an economical cost, for example, by reducing the labor cost required for the inspection.
