The determining step may include, if the body oxygen saturation is not within the standard body oxygen saturation range, determining whether the body oxygen saturation is within the standard body oxygen saturation range within a set time of the device. .

The step of recognizing the abnormal state is performed when the oxygen concentration does not change beyond the standard oxygen concentration and the carbon dioxide concentration and carbon monoxide concentration are not included in the standard concentration range based on the determined work status information. , when the device is not set to exercise mode or when the oxygen saturation in the body is not included in the standard oxygen saturation range in the body, the resolution and resolution are provided through the device within the set time of the device. It may include receiving input from port workers.

The step of recognizing the abnormal state may include recognizing the safety state of the maritime and port workers as an abnormal state when the input of the maritime and port workers is not received through the device within the set time of the device. You can.

In the step of recognizing the abnormal state, when the safety state of the maritime and port workers is recognized as an abnormal state, the current location data of the maritime and port workers is determined through the device, and the current location data of the maritime and port workers is determined. It may include transmitting a rescue request message including location data to a central center in real time.

Figure 1 is a diagram for explaining the general operation of a device and a central server for the safety of maritime and port workers according to an embodiment.

The device 100 may be worn on a part of the worker's body and operated for the safety of maritime and port workers. At this time, a safety system may be operated in the device 110 for the safety of maritime and port workers. Examples of the device 100 include smart phones, mobile phones, navigation devices, computers, laptops, digital broadcasting terminals, PDAs (Personal Digital Assistants), PMPs (Portable Multimedia Players), tablet PCs, wearable devices, etc. . In the embodiment, a wearable device will be described as an example of the device 110.

The central server 110 can monitor the safety of maritime and port workers. The central server 110 can monitor the worker's work safety status using sensing data transmitted from the device 100. For example, in the case of a ship, the central server 110 places the bridge of the ship as the central center because it is difficult to monitor the entire ship on land, and when an emergency situation occurs, the central server 110 contacts the onshore emergency contact network and the company representative through the emergency contact network. . However, in the case of merchant ships, the duty station of the bridge watch officer may move to another location during cargo work while anchored, so the central server can be made portable so that the watch officer can check emergency alarms and identify the location of accidents even in places other than the bridge. do.

The communication method between the device 100 and the central server 110 is not limited, and includes communication methods using communication networks that the network may include (e.g., mobile communication networks, wired Internet, wireless Internet, broadcasting networks) as well as communication methods between devices. Short-range wireless communications may also be included. For example, the network 120 may include a personal area network (PAN), a local area network (LAN), a campus area network (CAN), a metropolitan area network (MAN), a wide area network (WAN), and a broadband network (BBN). , may include one or more arbitrary networks such as the Internet. Additionally, the network may include, but is not limited to, any one or more of network topologies including a bus network, star network, ring network, mesh network, star-bus network, tree or hierarchical network, etc. .

More specifically, a wearable device is one that can be worn on a part of the user's (worker's) body, and may include, for example, a necklace type, a smartwatch type, etc. In addition to the necklace type and smartwatch type mentioned above, various types are applicable.

Wearable devices may include GPS, gas detecting, and safety alarm system functions. In particular, smartwatch-type wearable devices may additionally include functions to measure biometric information such as heart rate and oxygen saturation.

When the GPS function is activated in a wearable device, GPS displays the worker's movement path and identifies the accident point in the event of an accident, allowing the central server 110 to support personnel.

Gas detecting detects the O2, CO, and CO2 levels in the worker's workspace, and if the relevant levels are outside the normal range, it is recognized as abnormal and an alarm sound is heard and a message is displayed on the serial monitor. It can be programmed to continuously monitor whether the worker's working environment is suitable in a confined space.

The safety alarm system can generate a message alarm along with an alarm sound in the status window when the alarm setting is activated in the wearable device and the alarm is not reset within the time set by the worker. For example, a message alarm can be generated on the worker's serial monitor through a pre-alarm a certain amount of time (e.g., 5 minutes) before the set time of the safety alarm system expires. When the alarm setting is activated in the wearable device, the safety alarm system displays the worker's movement path and, if the alarm is not reset within the set time, transmits the current location data to the central server 110. Find out the worker's location at (110). If an accident occurs, the central server 110 can identify the accident point and send support and rescue personnel.

Heart rate and oxygen saturation are set as abnormal when the value input through the heart rate sensor deviates from the standard value by correcting the error value for the normal heart rate (60~100/min). If the abnormal state is longer than the set time, an alarm sounds. Together, status message alarms can be triggered. If the value input through the oxygen saturation sensor deviates from normal oxygen saturation (95-100%), it can be set as abnormal. If the abnormal state is longer than the set time, a status message alarm can be generated along with an alarm sound.

The central server 110 collects data related to the safety of workers through the CPU and can monitor the health status of workers wearing wearable devices, thereby providing support according to the situation.

For example, let's assume that an abnormal situation occurred in Worker B's work environment. For example, when worker B detects a decrease in oxygen concentration in the surrounding air when worker B enters a confined area, the device can warn workers of abnormal situations through abnormal status messages and a buzzer. You can. If an unexpected accident occurs to worker B, data can be sent to the central server 110 to rescue worker B, and the central server 110 can take measures such as sending rescue personnel. In addition, in the case of ships, workers (on-watch officers) periodically patrol the ship during watch hours at night. The safety alarm system is used to have workers select the reset button at each set time of the device, so that workers (on-watch officers) patrol the ship during the watch time. Any abnormalities can be checked on the central server 110. If the reset button of the safety alarm system cannot be selected due to the worker's abnormal condition, the worker's safety condition can be considered abnormal and measures such as sending rescue personnel by transmitting the current location data to the central server can be taken.

FIG. 2 is a block diagram for explaining the configuration of a device in one embodiment, and FIG. 3 is a flowchart for explaining a method for safety of maritime and port workers in one embodiment.

The processor of the device 100 may include a state determination unit 210 and an abnormality recognition unit 220. These processor components may be expressions of different functions performed by the processor according to control instructions provided by program codes stored in the device. The processor and its components may control the device to perform steps 310 to 320 included in the method for maritime and port worker safety of FIG. 3 . At this time, the processor and its components may be implemented to execute instructions according to the code of an operating system included in the memory and the code of at least one program.

The processor may load program code stored in a file of a program for methods for maritime and port worker safety into memory. For example, when a program is executed on a device, the processor can control the device to load program code from the program file into memory under the control of the operating system. At this time, the status determination unit 210 and the abnormality recognition unit 220 are each different functional expressions of the processor for executing the subsequent steps 310 to 320 by executing instructions of the corresponding portion of the program code loaded in the memory. You can.

In step 310, the status determination unit 210 may determine work status information including work environment information and biometric information of maritime and port workers using sensing data acquired through sensing using a device. The status determination unit 210 obtains work environment information of maritime and port workers using the oxygen concentration, carbon dioxide concentration, or carbon monoxide concentration included in the acquired sensing data, and uses the heart rate or body oxygen saturation included in the acquired sensing data. It can be used to obtain biometric information of maritime and port workers. The status determination unit 210 may determine work status information based on the obtained work environment information of maritime and port workers and the acquired biometric information of maritime and port workers. For example, the status determination unit 210 may set in advance each standard information for determining work environment information including oxygen concentration and carbon dioxide/carbon monoxide concentration, and biometric information including heart rate and body oxygen saturation. Each standard information for judging information can be set. This standard information may be a value input by an administrator or worker of the central server.

Referring to Figure 4, it is a flow chart to explain detailed operations for the safety of maritime and port workers using a device. As the device operates (410), the status determination unit 210 may determine the worker's oxygen concentration (402). The state determination unit 210 may compare the oxygen concentration with a reference oxygen concentration range. The state determination unit 210 may determine the carbon dioxide concentration by determining the oxygen concentration when the oxygen concentration is within the standard oxygen concentration range. If the oxygen concentration is not within the standard oxygen concentration range, the state determination unit 210 may determine whether the oxygen concentration is within the standard oxygen concentration range within the set time of the device (403). For example, if the internal oxygen concentration in the worker's working space is not within the standard concentration range, the status determination unit 210 may determine the oxygen concentration to be abnormal.

The status determination unit 210 may determine the worker's carbon dioxide concentration and carbon monoxide concentration (404). The status determination unit 210 may determine whether the carbon dioxide concentration and carbon monoxide concentration are within the standard carbon dioxide concentration and standard carbon monoxide concentration ranges. If the carbon dioxide concentration and carbon monoxide concentration are within the standard concentration range, the state determination unit 210 may determine the worker's heart rate by determining that the carbon dioxide concentration and carbon monoxide concentration are normal (406). If the carbon dioxide concentration and carbon monoxide concentration are not within the standard concentration range, the state determination unit 210 may determine whether the carbon dioxide concentration and carbon monoxide concentration are within the standard concentration range within the set time of the device (405).

If the worker's heart rate is within the standard heart rate range, the status determination unit 210 can determine the worker's body oxygen saturation (409). If the worker's heart rate is not within the standard heart rate range, the state determination unit 210 may determine whether the heart rate is within the standard heart rate range within the set time of the device (407). If the worker's heart rate is not within the reference heart rate range within the device's set time, the state determination unit 210 may determine whether the device is set to the exercise mode (408). The state determination unit 210 may determine a normal heart rate when the device is set to an exercise mode, and may determine an abnormal heart rate when the device is not set to an exercise mode. .

The status determination unit 210 may determine the work status information as normal when the worker's body oxygen saturation is within the standard body oxygen saturation range. If the worker's body oxygen saturation is not within the standard body oxygen saturation range, the status determination unit 210 may determine whether the body oxygen saturation is within the standard body oxygen saturation range within the set time of the device (410). . The state determination unit 210 may determine that the body oxygen saturation is normal if the body oxygen saturation falls within the standard body oxygen saturation range within the set time of the device.

In step 320, the abnormality recognition unit 220 may recognize the worker's safety status as abnormal depending on whether or not the maritime and port worker's input is received through the device within the set time of the device based on the determined work status information. there is. Based on the determined work status information, the abnormality recognition unit 220 sets the device to exercise mode when the oxygen concentration does not change to more than the standard oxygen concentration and when the carbon dioxide concentration and carbon monoxide concentration do not fall within the standard concentration range. If any of the following conditions are met (403, 405, 407, 408, 410) or the body oxygen saturation is not within the standard body oxygen saturation range, the safety status of maritime and port workers is abnormal. Recognizable (412).

At this time, if it is determined that the oxygen saturation is normal, the abnormality recognition unit 220 may determine that the worker's work status information is normal if it receives input from maritime and port workers received through the device within the device's set time. . In other words, the abnormality recognition unit 220 determines that the internal oxygen concentration, internal carbon dioxide concentration/internal carbon monoxide concentration, heart rate, and body oxygen saturation are all normal, and thus the input of maritime and port workers received through the device within the set time of the device. can receive. The abnormality recognition unit 220 may recognize the worker's safety status as normal when the worker's input, for example, an alarm, is reset within the device's set time.

On the other hand, if the abnormal recognition unit 220 determines that the oxygen saturation is normal and does not receive input from maritime and port workers through the device within the set time of the device, the abnormal recognition unit 220 The safety state can be recognized as an abnormal state (412). When the safety status of maritime and port workers is recognized as abnormal, the abnormality recognition unit 220 determines the current location data of the maritime and port workers through the device, and includes the current location data of the determined maritime and port workers. A rescue request message can be sent to the central center in real time (413).

Figure 5 is a diagram for explaining an operation of displaying information on a worker's work status on a device, according to an embodiment.

The worker can use the device to activate all five functions, including internal oxygen concentration, internal carbon dioxide and carbon monoxide concentration, the worker's heart rate, the worker's body oxygen saturation, and a safety alarm system (a system in which the worker periodically resets the alarm). The function can be selectively turned off as needed. Workers can selectively activate each function through the device screen 500.

For example, when multiple workers work together in the same place, the function of the safety alarm system is unnecessary, so the safety alarm system must be deactivated, and when a person on duty performs patrol duties during night patrol, the function of the safety alarm system is You can prevent accidents by activating. At this time, the function including the worker's heart rate and body oxygen saturation can only be used in the smartwatch type, so it can be selectively used separately from the necklace type.

Through sensing using the worker's device, the worker's work environment information and biometric information, internal oxygen concentration, internal carbon dioxide and carbon monoxide concentration, and the worker's heart rate can be measured on the device screen 500 and displayed in numerical values. Additionally, whether the safety alarm system is activated (on/off) may also be displayed on the device screen 500.

Referring to FIG. 6, this is a diagram to explain the operation of setting a notification time on a device. Workers can set the alarm time through the device screen 500. A user interface for inputting time information and a user interface 610 for setting an alarm time after inputting time information may be displayed on the device screen 500. Workers can set the alarm time by entering time information and then selecting the 'Settings' user interface. When an alarm about the device's setting time occurs in the device, the worker can select the 'Reset' user interface 620 displayed on the device screen 500. Accordingly, the device can determine the worker's safety status as normal.

Figure 7 is a diagram for explaining the operation of transmitting a rescue request, according to one embodiment.

If the device determines that the worker's safety status is abnormal, it can generate a text message containing the worker's current location data. The device can transmit the generated text message to the central server. For example, a text message containing the worker's current location data may be displayed on the device screen 500. At this time, in addition to the central server, text messages can be sent using an emergency contact network set up by workers in advance.

As an example, we will explain the case of worker A, who was on night duty patrol wearing a smartwatch-type device, suddenly losing consciousness due to cerebral hemorrhage. If Worker A wearing the device loses consciousness due to a sudden cerebral hemorrhage while on patrol, the heart rate and oxygen saturation ranges fall outside the normal range due to the increase in heart rate and decrease in oxygen saturation of Worker A who operated the device, and the heart rate and oxygen saturation ranges exceed the normal range. Since the saturation level does not return to the normal range within the device's set time, the device may recognize the worker's safety status as abnormal and send a rescue message containing worker A's current location data to the central server. Alternatively, if Worker A, who is equipped with a smart watch type or necklace type device, loses consciousness due to a sudden cerebral hemorrhage while on patrol, the device may be used to protect Worker A's safety because Worker A did not reset the alarm within the device's set time. By recognizing the status as abnormal, a rescue message containing worker A's current location data can be sent to the central server.

As another example, we will explain a situation where Worker B, who was working on the upper deck of a ship, lost his footing and fell into the sea. If Worker B, wearing a smartwatch-type device, falls while working and falls into the sea, Worker B's heart rate will rise and the heart rate value will not recover to the normal range within the device's set time, so the device will protect Worker B's safety status. Recognizing it as an abnormal state, a rescue message containing worker B's current location data can be sent to the central server. Alternatively, if Worker B, wearing a smartwatch-type or necklace-type device, falls while working and falls into the sea, Worker B does not reset the alarm within the device's set time, so the device recognizes Worker B's safety status as abnormal. Thus, a rescue message containing worker B's current location data can be sent to the central server. This can equally apply to a fall accident on land rather than a fall into the sea. Let us use the example of a situation in which Worker B, who was working at a ship dock construction site, lost his footing and fell to land. If Worker B, wearing a smartwatch-type device, slips while working and falls on land, Worker B's heart rate will rise and the heart rate value will not recover to the normal range within the device's set time, so the device will be used to determine Worker B's safety status. can be recognized as an abnormal state and a rescue message containing worker B's current location data can be sent to the central server. Alternatively, if Worker B, wearing a smartwatch type or necklace type device, slips while working and falls on land, Worker B does not reset the alarm within the device's set time, so the device changes Worker B's safety status to an abnormal state. By recognizing this, a rescue message containing worker B's current location data can be sent to the central server.

As another example, we will explain a situation where Worker C discovers a missing tool while working and quickly runs to get the necessary tool. If Worker C, who was working while wearing a smartwatch-type device, runs to retrieve a tool he missed, setting the device to exercise mode will restore Worker C's safety to a normal state even if his heart rate is outside the normal range. It can be recognized.

According to the embodiment, help can be provided to port facilities where there is a lot of heavy equipment work and to personnel working at sea, where it is relatively difficult to receive medical support, rather than on land, where it is easy to receive medical support.
