Description

Technology Field

[0001] The present invention relates to a technology for efficiently managing multiple alarms occurring during navigation, and more specifically, to an alarm control system capable of preventing alarm overload and improving operational stability by classifying and controlling alarms by prioritizing the determination of a primary alarm based on static and dynamic situational information. Background Technology

[0003] In general, modern ships are equipped with various navigation equipment and safety systems, and these devices include various alarm functions to enable early detection and response to dangerous situations that may occur during navigation.

[0004] These warnings help navigators respond quickly by alerting them to situations that may threaten the safety of ship operations, such as abnormal ship position, deviation from the course, equipment failure, communication errors, and adverse weather conditions.

[0005] However, it is common for multiple warnings to occur simultaneously due to a single cause during navigation. For example, if a Global Navigation Satellite System (GNSS) error occurs, a combination of warnings—such as reduced position reliability, route tracking errors, and radar-position discrepancies—can occur at once.

[0006] In such situations, auditory and visual alarms are excessively output, leading to an 'alarm flooding' phenomenon.

[0007] A surge in warnings interferes with the navigator's perception and judgment, causing problems such as missing the most important warnings or delaying the verification of the warnings themselves.

[0008] This can delay immediate responses such as collision avoidance, course maintenance, and emergency evasion, potentially leading to serious accidents.

[0009] To address this, some systems use methods such as pre-assigning alarm priorities or limiting alarm output for specific equipment or signals.

[0010] In addition, some advanced systems provide alarm filtering functions based on user settings, allowing you to configure them to hide low-importance alarms.

[0011] However, because this method has fixed alarm priorities or must be set manually by the user, it is difficult to respond flexibly to risks in actual navigation situations or changes in the environment.

[0012] For example, in coastal navigation, warnings with a high risk of collision should be prioritized, while in open-ocean navigation, warnings related to positional accuracy may be important; however, existing methods are unable to provide dynamic responses tailored to these specific operating environments.

[0013] Furthermore, user-configuration-based alarm suppression methods carry the risk that important alarms may be suppressed due to configuration errors or carelessness, and because they cannot automatically analyze or classify the causal relationship between primary and derivative alarms, they fail to completely eliminate unnecessary alarm recognition tasks and the burden of repetitive operations.

[0014] This has been disclosed in Korean Registered Patent No. 10-1903985 and Korean Registered Patent No. 10-1882417. The problem to be solved

[0016] The present invention has been devised based on the technical background described above. The invention provides a main alarm-centered integrated alarm management system that collects multiple alarms generated from each navigation equipment of a ship, calculates risk levels based on static and dynamic information, distinguishes between main alarms and derivative alarms to resolve them collectively with a single recognition, prevents alarm overload through the linkage of external sensor units and control servers, and improves recognition efficiency and operational safety. means of solving the problem

[0018] To achieve the above objectives, the present invention comprises a signal processing unit that collects and identifies all alarms occurring on a ship; a control unit that selects a primary alarm by reflecting static and dynamic conditions for all said alarms and classifies the remaining alarms associated with the primary alarm as derivative alarms; and a user display unit that visually displays the primary alarm and derivative alarms and confirms that the user has recognized them, wherein when the user recognizes the primary alarm, the derivative alarm is processed as automatically recognized, so that when the primary alarm is resolved, the derivative alarm is automatically resolved.

[0019] In addition, the control unit is configured to calculate the risk level of each alarm by reflecting static information based on the design characteristics of a plurality of equipment installed on the vessel and dynamic information based on the vessel's operating section, steering mode, weather, and sea conditions, and to dynamically select the main alarm according to the risk level.

[0020] In addition, the control unit determines the derived alarm using the causal relationship, co-occurrence pattern, and correlation between the main alarm and the remaining alarms.

[0021] In addition, the control unit selects the main alarm by switching weights or thresholds according to the operating profile if the vessel follows any one of a plurality of pre-set operating profiles, such as a coastal area, an open sea area, or an ice area.

[0022] Additionally, the control unit includes a recognition processor that automatically processes the derivative alarm associated with the main alarm as recognized when recognition confirmation information is received from the user display unit that the user has acknowledged the main alarm, and the recognition processor is configured to record the recognized result in a database.

[0023] In addition, the control unit further includes a resolution processor that resolves the main alarm and the derivative alarm according to recognition confirmation information, and, according to the resolution information generated by the resolution processor, controls the command transmitter of the signal processing unit to stop, restart, or switch the operation of the navigation equipment, as well as the alarm output device of each navigation equipment, to a safe mode.

[0024] In addition, when the above control unit determines that the risk level exceeds a preset threshold and is an alarm that must be urgently resolved, it controls the operation of the navigation equipment to be stopped or restarted first or switched to a safety mode through the command transmitter of the signal processing unit even before user awareness.

[0025] In addition, the control unit recalculates the risk level of each alarm and re-selects the main alarm in the event of a change in the operating environment of the vessel, a change in equipment status, or the existence of an unresolved alarm.

[0026] In addition, the user display unit is configured to display the main alarm in a form distinct from the derivative alarm, output an auditory notification only for the main alarm, and restrict the auditory notification for the derivative alarm.

[0027] In addition, it further includes a communication unit that transmits the judgment result of the control unit and the user's awareness status to an external control server and receives and reflects external commands from the control server, wherein the communication unit is configured to generate and transmit integrated communication information by integrating the main alarm information, derived alarm information, awareness information, and resolution information from the control unit.

[0028] In addition, the communication unit is configured to detect status information including the network connection status, latency, and loss rate, and to control whether to proceed with communication with the control server based on the status information.

[0029] In addition, it further includes an external sensor unit that collects weather information, sea state information, and route information, and the control unit is configured to reflect the information input from the external sensor unit as dynamic information and use it for determining the main alarm.

[0061] FIG. 12 is an operation diagram of an external sensor unit according to one embodiment of the present invention.

[0063] Referring to FIG. 1, the core of the present invention is to automatically distinguish between alarms derived from the same cause among multiple alarms occurring within a ship, and to prioritize recognizing and processing the main alarm to prevent an alarm overload.

[0064] To this end, the control unit (100), signal processing unit (300), user display unit (500), database (700), communication unit (800), and external sensor unit (900) are combined and operate.

[0065] Unlike conventional methods that simply display various alarms occurring simultaneously from multiple navigation equipment (E) within a ship, the present invention has a structure that automatically distinguishes between a main alarm and a derivative alarm by analyzing the causal relationships of each alarm and reflecting static and dynamic situational information.

[0066] In particular, the most significant technical feature is that when the user recognizes the main alarm just once, all associated derivative alarms are automatically recognized and resolved, thereby preventing a surge of auditory alarms and significantly reducing the cognitive burden on the navigator.

[0067] The alarm control system (1) is composed of a control unit (100), a signal processing unit (300), a user display unit (500), a database (700), a communication unit (800), and an external sensor unit (900), and they interact with each other.

[0068] The signal processing unit (300) collects alarm signals generated from navigation equipment (E), converts them into normalized information, and transmits them to the control unit (100). The control unit (100) evaluates the risk level of each alarm using the input alarm information, static information from the database (700), and dynamic information from the external sensor unit (900).

[0069] Subsequently, the control unit (100) selects the alarm with the most fatal risk as the main alarm and classifies other alarms as derived alarms and transmits them to the user display unit (500).

[0070] The user display unit (500) audibly warns only the main alarm, and displays derivative alarms only visually, thereby suppressing unnecessary alarm sounds.

[0071] When the user recognizes the main alarm, the control unit (100) automatically resolves all related derivative alarms and resets or suppresses the alarm output of each navigation equipment (E) through the signal processing unit (300).

[0072] The database (700) stores basic data necessary for determining the main alarm, such as static information, operation information, and environmental information, and the control unit (100) refers to this and adjusts the weight according to dynamic conditions such as the operation section and weather conditions.

[0073] The communication unit (800) transmits control results and alarm status to an external control server (S) and, if necessary, receives policy commands or remote control signals from the outside. The external sensor unit (900) collects real-time environmental information such as weather, sea, and shipping routes and reflects it in the dynamic judgment of the control unit (100).

[0074] A structure is realized that prevents a surge in alarms by automatically selecting a primary alarm through static and dynamic situation analysis when a complex alarm occurs during ship operation, and enabling the user to collectively recognize and resolve all related alarms with a single awareness.

[0075] In addition, by including a dynamic control function that re-evaluates the main warning based on environmental changes or fluctuations in operating conditions, it ensures much higher operational safety and reliability compared to existing systems.

[0076] Referring to FIG. 2, the control unit (100) includes a static weight (110), a dynamic weight (120), a risk assessor (130), a main alarm judgment unit (140), an alarm classifier (150), a perception processor (160), a resolution processor (170), and a re-judgmenter (180), and operates as a central logic unit that determines and controls alarms by combining regular information (351) provided by the signal processing unit (300), static information (111) provided by the database (700), and dynamic information (121) provided by the external sensor unit (900).

[0077] The static weight (110) calculates the basic risk contribution of each alarm by referring to static information (111) representing fixed attributes such as equipment importance, equipment characteristics, and ship type. The dynamic weight (120) calculates the situation weight by reflecting dynamic information (121) representing real-time conditions such as weather, sea, and shipping routes.

[0078] The risk assessor (130) calculates the overall risk level (131) of each alarm by combining the two weights above, and the main alarm judgment unit (140) selects the alarm with the highest lethality at the current time as the main alarm by switching the threshold or weight according to the flight profile based on the risk level (131).

[0079] The alarm classifier (150) generates main alarm information (151) and derived alarm information (153) by applying a causal and simultaneous occurrence pattern between the selected main alarm and regular information (351) and provides them to the user display unit (500).

[0080] When the recognition processor (160) receives recognition confirmation information (551) input from the recognition input device (550) of the user display unit (500), it processes the main alarm and the derivative alarms dependent thereon as being recognized collectively and records the result as an alarm information log (571).

[0081] The resolution processor (170) generates resolution information (171) when the main alarm satisfies the resolution condition or the recognition processing is completed, and transmits it to the command transmitter (370) of the signal processing unit (300), thereby controlling the suppression of alarm output, alarm reset, suspension of equipment operation, restart, or switching to safety mode of each navigation equipment (E).

[0082] The re-evaluation unit (180) ensures situational adaptability by triggering to recalculate the risk level (131) when it detects environmental changes or the persistence of unresolved alarms, thereby re-selecting the main alarm.

[0083] With this configuration, the control unit (100) realizes an operation that can automatically recognize and resolve related derivative alarms by recognizing the main alarm once, thereby suppressing alarm overload and reducing the burden of recognition.

[0084] Referring to FIG. 3, the signal processing unit (300) includes an alarm receiver (310), an equipment identifier (330), a signal regulator (350), and a command transmitter (370).

[0085] The alarm receiver (310) receives raw alarm signals generated from navigation equipment (E) through various interfaces.

[0086] The equipment identifier (330) identifies the equipment and channel generating the received alarm and assigns an equipment ID, and the signal regularizer (350) converts the different codes or formats for each equipment into regular information (351) in a system common format.

[0087] Regular information (351) is provided to the static weight (110), dynamic weight (120), and risk assessor (130) of the control unit (100) to serve as a criterion for subsequent judgment.

[0088] When the command transmitter (370) receives the resolution information (171) of the control unit (100), it transmits a command to control the alarm output device of the navigation equipment (E), reset the alarm, stop or restart the operation, or switch to a safety mode.

[0089] The signal processing unit (300) can normalize heterogeneous alarms of different formats generated from different navigation equipment (E) and execute control commands for said navigation equipment (E), thereby increasing the consistency of the higher-level judgment logic and the effectiveness of equipment control.

[0090] Referring to FIG. 4, the user display unit (500) includes a main alarm indicator (510), a derivative indicator (530), a recognition input device (550), a record output device (570), and a control connector (590).

[0091] The main alarm indicator (510) highlights the main alarm information (151) provided by the control unit (100) with colors, flashing, and arrangements, and applies a policy to output auditory notifications only for the main alarm.

[0092] The derivative indicator (530) displays the derivative alarm information (153) as a visual element that is clearly distinguishable from the main alarm, and limits auditory notifications to suppress an auditory alarm surge.

[0093] The cognitive input device (550) generates cognitive operation of the user (U) as cognitive confirmation information (551) and transmits it to the cognitive processor (160) of the control unit (100).

[0094] The record output device (570) stores and exports the alarm information log (571) to enable auditing or post-analysis, and the control connector (590) provides the user with the connection status received from the network verifier (850) of the communication unit (800) to enable real-time verification of communication availability.

[0095] With this UI structure, users can process related derivative alerts collectively by recognizing only the main alert without having to check individual alerts one by one, which has the effect of significantly reducing the cognitive burden in actual flight situations.

[0096] Referring to FIG. 5, the communication unit (800) includes an information transmitter (810), a command receiver (830), and a network checker (850).

[0097] The information transmitter (810) collects and integrates the summary of the main alarm information (151), derived alarm information (153), awareness confirmation information (551), resolution information (171), and alarm information log (571) from the control unit (100) to form integrated communication information (811) and transmits it to the control server (S).

[0098] The command receiver (830) receives external command information (831), such as remote verification, policy update, and test alarm generation, from the control server (S) and transmits it to the control unit (100).

[0099] The network verifier (850) calculates network quality such as connection status, latency, and loss rate, controls the transmission and reception policies of the information transmitter (810) and command receiver (830), e.g., retries, delayed transmission, and buffering, and the status information is also provided to the control connector (590) of the user display unit (500).

[0100] The configuration of the communication unit (800) in this way increases the reliability of the control linkage and maintains the continuity of alarm processing even when communication quality deteriorates.

[0101] Referring to FIG. 6, the external sensor unit (900) includes a weather sensor (910), a marine sensor (930), a navigation sensor (950), and a sensor processor (970).

[0102] The weather sensor (910) measures weather elements such as wind speed, atmospheric pressure, and visibility, the sea sensor (930) measures sea conditions such as wave height, current, and water temperature, and the route sensor (950) provides data related to the route, position, and course.

[0103] The sensor processor (970) normalizes and fuses the sensor data to generate dynamic information (121) and provides it to the dynamic weighter (120) of the control unit (100), and if necessary, stores it in the environmental information (730) and operation information (750) of the database (700).

[0104] This configuration has the effect of allowing the main warning judgment device (140) to make a decision appropriate to the situation by reflecting changes in the sailing section, for example, coastal, open sea, ice area, etc., or sudden weather changes in real time.

[0105] The components of FIGS. 2 to 6 operate organically with one another. Specifically, when the signal processing unit (300) provides regular information (351), the control unit (100) calculates the risk level (131) by reflecting static information (111) and dynamic information (121), generates main alarm information (151) / derived alarm information (153), and provides it to the user display unit (500).

[0106] When the user (U) recognizes the main alarm through the recognition input device (550), the recognition processor (160) automatically recognizes the related derivative alarm, and the resolution processor (170) generates resolution information (171) and transmits it to the command transmitter (370) to control the navigation equipment (E).

[0107] The communication unit (800) transmits integrated communication information (811) to the control server (S) and receives and reflects external command information (831), and the external sensor unit (900) continuously provides dynamic information (121) so that the main alarm re-selection loop by the re-distributor (180) is performed in a timely manner.

[0108] Thus, the present invention effectively prevents a surge in alarms and improves operational safety through two key features: automation that recognizes and resolves related derivative alarms collectively with a single recognition of the main alarm, and situation-adaptive main alarm selection based on static and dynamic weights.

[0109] Referring to FIG. 7, when a raw alarm occurs in the navigation equipment (E), the alarm receiver (310) receives it in real time in response to multiple protocols, such as NMEA (National Marine Electronics Association), serial, Ethernet, digital I / O (Input / Output), etc., assigns a timestamp, and loads it into an input queue.

[0110] The alarm receiver (310) can be designed to perform noise removal and bounce filtering, and to apply hysteresis and redundancy suppression policies for short interval repetitions of the same alarm, thereby primarily mitigating unnecessary signal bursts.

[0111] The raw signal output from the alarm receiver (310) is transmitted to the equipment identifier (330), and the equipment identifier (330) identifies the source of the alarm and assigns an equipment ID using metadata such as the port, channel, frame header, and equipment serial.

[0112] The equipment identifier (330) performs frame checks, such as Cyclic Redundancy Check (CRC) and sequence number checks, to determine whether data has been tampered with or lost, and branches unconfirmed signals to a pending queue to prevent misjudgment in subsequent steps.

[0113] The result of the equipment identifier (330) is transmitted to the signal regularizer (350), and the signal regularizer (350) generates regular information (351) by mapping different alarm codes and severity notations by manufacturer or equipment to a common system.

[0114] The standard information (351) can be structured to include at least an equipment ID, a standardized alarm code, a time of occurrence, a status, and a duplicate suppression flag, and can be defined to include additional parameters specific to the equipment, such as an integrity quality indicator, radar tracking reliability, etc., as extension fields if necessary.

[0115] The signal normalizer (350) also includes time order guarantee and delayed packet processing logic so that normal information (351) is provided to the control unit (100) even in the event of disturbance or communication congestion.

[0116] The generated regular information (351) is transmitted to the control unit (100) via a message bus or shared memory interface, and the control unit (100) performs risk calculation and determines the main alarm and derived alarm based on the regular information (351).

[0117] When the control unit (100) completes the determination of recognition or resolution of the main alarm, the resolution processing result is generated as resolution information (171) and returned to the signal processing unit (300).

[0118] The resolution information (171) can be defined to include an identifier of the target alarm, a type of command, for example, buzzer suppression, alarm reset, operation stop, restart, safe mode switching, etc., an application time, and a validity period.

[0119] When the command transmitter (370) receives the resolution information (171), it converts it into a low-level control frame in accordance with the control protocol of the navigation equipment (E) and ensures sequential or mutually exclusive execution according to the safety state machine.

[0120] For example, if a restart command overlaps while a stop operation command is being executed, the command transmitter (370) checks the priority policy and equipment status to prevent a conflict.

[0121] Additionally, the command transmitter (370) ensures the reliability of the execution of the resolution information (171) even in an unstable link, including transmission confirmation, retry, timeout, and rollback rules, and sends the results of the command execution success and failure to the control unit (100) so that they are reflected in subsequent judgments.

[0122] If it is determined that the navigation equipment (E) is in a state where it cannot accept a command, the command transmitter (370) may selectively perform fail-safe alternatives such as switching to a safe mode or limiting the alarm sound.

[0123] Through the configuration of the signal processing unit (300) as described above, the normalization pipeline centered on the signal normalizer (350) eliminates equipment heterogeneity and variability of the raw signal, thereby enabling the control unit (100) to stably perform risk calculation and structurally suppress alarm surges by integrating multiple alarms derived from the same cause into a single main alarm.

[0124] In addition, by the command transmitter (370) confirming and executing the resolution information (171) as a control command for each piece of equipment, the alarm sound suppression and reset of related derivative alarms are applied collectively at the equipment level with only one recognition of the main alarm by the user, and the result is reflected as feedback to the state judgment of the control unit (100), thereby enabling rapid extinguishing of the remaining alarms.

[0125] Consequently, the signal processing unit (300) performs the dual roles of reliable normalization of heterogeneous alarms and safe and accurate execution of resolution commands.

[0126] Referring to FIG. 8, the control unit (100) is structured such that a static weight (110), a dynamic weight (120), a risk assessor (130), and a main alarm judgment unit (140) operate sequentially based on regular information (351) input from the signal processing unit (300).

[0127] Additionally, the database (700) provides environmental information (730) and navigation information (750) necessary to calculate static information (111) and dynamic information (121) to the static weight (110) and dynamic weight (120), respectively.

[0128] The static weight (110) retrieves static information (111) from the database (700) that includes static attributes such as the importance of the equipment, whether it is redundant, the installation location, and the maintenance grade.

[0129] The static weight (110) calculates the basic risk level of each piece of equipment or alarm based on this static information (111), and assigns different weights depending on the importance of the equipment or the class of the vessel even if the same regular information (351) is input.

[0130] For example, warnings related to the steering gear and propeller are set to have a higher priority than general navigation systems.

[0131] Since this static weighting reflects the intrinsic risk contribution of the equipment, it has the effect of clearly distinguishing the priority between the equipment when the control unit (100) determines the main alarm in the subsequent stage.

[0132] The dynamic weight (120) receives environmental information (730) and operation information (750) from the database (700) and generates dynamic information (121) that takes into account real-time changing operation conditions.

[0133] Environmental information (730) includes data such as wind speed, wave height, current, visibility, and water temperature obtained from a weather sensor (910) and a marine sensor (930), and navigation information (750) includes route risk, navigation section, and navigation mode provided by a route sensor (950), such as automatic navigation and manual steering, and includes the ship's position, etc.

[0134] The dynamic weight (120) analyzes this data and corrects the situational risk of each alarm.

[0135] For example, when navigating a narrow channel with short visibility and high waves, the weight of radar warnings or collision warnings is set to increase automatically.

[0136] Conversely, in stable environments such as open-ocean voyages, a relatively lower dynamic weight is assigned to the same warning.

[0137] Thus, the dynamic weight (120) enables real-time responsive risk assessment by reflecting the operating environment that changes according to time and place.

[0138] The static information (111) and dynamic information (121) generated as a result of the static weight (110) and dynamic weight (120) are input into the risk assessor (130).

[0139] The risk assessor (130) combines two sets of information to quantitatively calculate the risk level of each alarm. At this time, the risk assessor (130) considers not just a simple weighted sum, but also duration, recurrence frequency, and interdependence between alarms.

[0140] Specifically, the risk level of each alarm is calculated by summing static and dynamic factors, applying a logarithmic time weight to alarms that persist for a certain period, and applying a correlation correction factor when multiple alarms derived from the same cause occur simultaneously.

[0141] In addition, the risk assessor (130) can be configured to adjust the ratio of static and dynamic elements according to the characteristics of each navigation section, prioritize collision and grounding risks in coastal navigation, and emphasize navigation reliability and communication-related risks in open ocean navigation.

[0142] The risk level (131) calculated as a result of the risk assessor (130) is normalized to a value between 0 and 100 and used as a comparison standard in other modules within the control unit (100).

[0143] The risk level (131) calculated in this way is input into the main alarm judgment unit (140). The main alarm judgment unit (140) compares the risk levels of all alarms within a certain time window and selects the alarm with the highest value as the main alarm candidate.

[0144] Subsequently, the final main warning is determined by applying thresholds set according to the operation profile, such as the operation section, route conditions, and vessel type.

[0145] For example, during coastal navigation, the thresholds for collision warnings and grounding warnings are set low to allow for a more sensitive response, and during open ocean navigation, the thresholds for navigation reliability degradation or communication failure warnings are lowered to allow for early detection of long-term risks.

[0146] The item confirmed as the main alarm is separated from the derived alarm in the subsequent alarm classifier (150) and transmitted to the user display unit (500), and then passes through the recognition processor (160) and the resolution processor (170) to finally suppress the alarm overload of the system.

[0147] The risk level (131) is a value that quantitatively represents the actual severity of the alarm and is an indicator that reflects the actual risk appropriate to the situation rather than the number of alarm occurrences or types.

[0148] For example, when navigating a narrow channel with visibility of 500 meters or less and strong currents, if three warnings occur—radar tracking instability, increased track deviation, and deterioration of GNSS (Global Navigation Satellite System) integrity—the static weighter (110) assigns 30 points for radar, 30 points for track control, and 20 points for GNSS according to the importance of each piece of equipment, and the dynamic weighter (120) assigns 25 points, 27 points, and 12 points respectively according to environmental risk.

[0149] The risk assessor (130) combines this to calculate the risk of radar 82, track control 86, and GNSS 52.

[0150] The main alarm judgment unit (140) determines the track control alarm as the main alarm and classifies the other two alarms as derived alarms, thereby increasing the concentration and judgment efficiency of the alarms. On the other hand, in open ocean navigation situations, even if the same three alarms occur, the GNSS integrity degradation alarm is evaluated as having the highest risk and can be designated as the main alarm.

[0151] Additionally, if there are any alarms remaining that are not the main alarm or the derivative alarm after the main alarm and the derivative alarm have been selected by the main alarm judgment unit (140), the main alarm judgment unit can repeat the process of generating the main alarm and the derivative alarm again for the remaining alarms so that all alarms can be designated as the main alarm and the derivative alarm.

[0152] Referring to FIG. 9, the procedure illustrates receiving a risk level (131) as input within the control unit (100), determining the main alarm and the derivative alarm, and then generating the resolution information (171) through user recognition and equipment control.

[0153] The risk level (131) is a value calculated based on regular information (351) through a static weight (110), a dynamic weight (120), and a risk assessor (130).

[0154] The main alarm judgment device (140) selects the alarm that has the greatest impact on ship safety at the current time as a main alarm candidate based on the magnitude of the risk level (131) and a threshold value tailored to the operation profile.

[0155] The main alarm judgment device (140) can be designed to determine a single main alarm by sequentially applying temporal precedence, equipment importance, and recurrence frequency when there are multiple alarms with the same risk level, and this process has the effect of allowing the user to focus on one main alarm even when multiple alarms overlap.

[0156] When the main alarm is confirmed, the alarm classifier (150) operates to analyze the causal relationship and simultaneous occurrence pattern between the main alarm and other alarms and generates main alarm information (151) and derived alarm information (153).

[0157] The alarm classifier (150) uses a correlation table based on a predefined cause-and-effect rule and a history.

[0158] For example, in a situation where GNSS integrity degradation is dominant in risk (131) and confirmed as the main warning, the increase in automatic navigation track deviation and radar tracking instability are grouped into derived warning information (153) dependent on the same cause.

[0159] The main alarm information (151) and derived alarm information (153) configured in this way are transmitted to the user display unit (500), and the user display unit (500) visually places the main alarm information (151) as the highest priority and allows auditory alarms only to the main alarm to suppress the surge of auditory stimuli.

[0160] The derived warning information (153) is visually distinguished and displayed, but the auditory warning is limited, so the cognitive burden on the navigator is significantly reduced.

[0161] When the user checks the main alarm through the user display unit (500), the recognition confirmation information (551) is generated in the recognition input device (550) and transmitted to the recognition processor (160) of the control unit (100).

[0162] The recognition processor (160) compares the recognition confirmation information (551) with the connection information of the main alarm and the derivative alarm managed by the alarm classifier (150) and converts the main alarm and all derivative alarms dependent thereon into a collective recognition state.

[0163] The cognitive processor (160) also verifies the sender and time of the cognitive confirmation information (551) to prevent data integrity and manipulation errors, suppresses duplicate cognition, and triggers to record the cognition result in the database (700) as an alarm information log (571).

[0164] In this way, since multiple derivative alarms are simultaneously recognized and processed with a single operation for a single main alarm, it has the effect of reducing operation time in emergency situations.

[0165] When batch recognition is completed in the recognition processor (160), the resolution processor (170) operates to check the resolution conditions and generate resolution information (171).

[0166] The resolution processor (170) applies a policy that if the main alarm corresponds to the root cause and is resolved, the derivative alarm should also be automatically extinguished, and according to the policy, the resolution information (171) includes specific commands such as suppressing the equipment buzzer, resetting the alarm, stopping or restarting the equipment operation, and switching to safe mode.

[0167] The resolution information (171) is transmitted to the command transmitter (370) of the signal processing unit (300) and is actually executed in the navigation equipment (E). The result of the execution is returned to the control unit (100) and reflected in the log, and if a failure or delay occurs, the resolution processor (170) activates a retry policy or prioritizes the application of a safe mode switch to minimize residual risk.

[0168] Due to the presence of the resolution processor (170), practical measures at the equipment level are quickly performed collectively after user recognition, thereby realizing the effect of quickly normalizing the alarm state.

[0169] The re-evaluation unit (180) continuously monitors the integrated ship information (710) accumulated in the database (700) and detects whether there are sudden changes in the environment, changes in the operation mode, or remaining unresolved alarms.

[0170] The integrated ship information (710) includes ship operation parameters such as steering mode, course change, and propeller status, and the re-determiner (180) triggers the main alarm judgment unit (140) to resume judgment when these parameters change.

[0171] For example, if the risk level (131) remains above a threshold for a certain period of time despite the execution of the main alarm resolution information (171), the re-evaluation unit (180) instructs the main alarm to be re-selected, and the alarm classifier (150) recalculates new main alarm information (151) and derived alarm information (153).

[0172] This process has the effect of ensuring dynamic adaptability by preventing judgments from becoming fixed in response to changes in the situation.

[0173] Starting from the risk level (131), it follows the main alarm judgment unit (140), alarm classifier (150), user display unit (500), recognition processor (160), and resolution processor (170), forming a closed-loop structure in which the integrated ship information (710) and re-evaluation unit (180) of the database (700) perform constant monitoring.

[0174] With this closed-loop structure, a derivative alarm is automatically recognized with a single recognition of the main alarm, and the resolution information (171) is actually executed at the equipment level, and a re-evaluation is made immediately when a change in the situation is detected.

[0175] Consequently, the present invention integrates and manages multiple alarms through simple user operation centered on the main alarm, and enables rapid resolution linked to equipment control, thereby structurally suppressing auditory alarm surges, significantly reducing the cognitive burden on navigators, and improving the safety and reliability of ship operation.

[0176] Referring to FIG. 10, the user display unit (500) includes a main alarm indicator (510), a derivative indicator (530), a recognition input device (550), and a record output device (570), and supports the user (U) in quickly distinguishing between the main alarm and the derivative alarm and recognizing them, and generating necessary recognition confirmation information (551).

[0177] Each module is designed to receive main alarm information (151) and derived alarm information (153) provided by the control unit (100), apply screen layout, visual emphasis, and auditory notification policies, convert user (U) operations into recognition confirmation information (551), and transmit them to the recognition processor (160) of the control unit (100).

[0178] In addition, the alarm information log (571) can be viewed and exported from the record output device (570) to support auditing and post-analysis.

[0179] When the main alarm indicator (510) receives the main alarm information (151), it places it on the top layer of the screen and the viewing area to prioritize guiding the user's (U) gaze.

[0180] The main alarm indicator (510) hierarchically expresses the importance of the alarm by combining visual elements such as color contrast, flashing cycle, size, and accent border, and applies a policy so that auditory notifications are activated only for the main alarm.

[0181] At this time, the auditory notification may include a history-based suppression logic that suppresses noise surges by limiting the volume upper limit and repetition interval, and automatically suppresses the sound of the recurrence signal for the main alarm that has already been recognized.

[0182] The main alarm indicator (510) can be implemented to present guidance messages and recommended measures, such as recommendations for switching to manual steering or deceleration, by referring to the risk level (131) or operation profile included in the main alarm information (151), and when the user (U) expands the details, the list of cause alarm candidates and related derivative alarms is displayed in conjunction.

[0183] This behavior provides the effect of reducing cognitive burden by allowing the user (U) to focus on a single main alarm without scattering judgment among multiple alarms.

[0184] When the derivative indicator (530) receives derivative alarm information (153), it is placed in a visual style that is clearly distinguishable from the main alarm indicator (510).

[0185] The derivative indicator (530) displays multiple derivative alarms dependent on the same cause as cluster cards to prevent the list length from increasing excessively, and within the cluster, auxiliary indicators such as the order of occurrence, duration, and repetition frequency are displayed as small badges.

[0186] The auditory notification of the derivative indicator (530) is disabled by default, and only specific derivative alarm groups may be allowed short sound effects in a limited manner by mandatory safety policies.

[0187] When the main alarm is recognized or resolved, the derivative indicator (530) automatically updates the state of the cluster to remove visual emphasis and leave only the remaining items, thereby maintaining the visibility of the alarm panel.

[0188] This configuration can reduce the level of information noise on the panel and increase the speed at which the user (U) understands the situation, even in situations where a large number of derived alerts are generated.

[0189] The cognitive input device (550) detects the operation of the user (U) and generates cognitive confirmation information (551).

[0190] The cognitive input device (550) provides a verification flow including long press, double check, authorization verification, attachment of user (U) identifier, and timestamp assignment to prevent errors.

[0191] When the recognition operation for the main alarm is completed, the recognition input device (550) configures recognition confirmation information (551) including the identifier of the main alarm, the user (U) identifier, the input time, and the identifier of the derived alarm set connected to the main alarm, and transmits it to the recognition processor (160) of the control unit (100).

[0192] At this time, the recognition input device (550) maintains a list of recently recognized main alarms in a local cache to prevent recognition duplication, and if repeated input occurs within a certain period of time for the same main alarm, it displays a warning message and restricts transmission to only once.

[0193] In addition, to prevent loss of the recognition confirmation information (551) in abnormal situations such as communication failure or power fluctuations, it may include fault-tolerant logic that stores it in a temporary storage and automatically retransmits it when communication is restored.

[0194] Through this processing, derivative alarms connected to a single operation for a single main alarm are collectively recognized, and subsequently, the resolution information (171) generated by the resolution processor (170) can be quickly led to the equipment control stage.

[0195] The record output device (570) provides the alarm information log (571) to the user (U). The record output device (570) can provide two modes: a time-axis-based timeline view and a table view, and expresses the interrelationships of the main alarm, derived alarm, awareness confirmation information (551), and resolution information (171) as a linear sequence and a link icon.

[0196] The alarm information log (571) allows for the extraction of only the operation history of specific equipment, specific route sections, and specific users (U) through filtering and search functions, thereby reducing the time required for auditing and cause analysis.

[0197] In addition, the record output device (570) supports standard format export for linkage with an external storage device or control server (S), and can be used for automatic report generation or fleet-level analysis after operation ends.

[0198] If necessary, personal information items can be masked according to access rights, and configured to apply automatic retention and deletion schedules in accordance with the statutory retention period or company policy.

[0199] The four modules of the user display unit (500) operate in combination with each other. When the main alarm information (151) is input, the main alarm indicator (510) immediately performs a highlighting display, and when the derived alarm information (153) is input together, the derived indicator (530) groups it into cluster cards and places them in the lower area of ​​the screen.

[0200] When the user (U) executes the recognition button provided by the main alarm indicator (510), the recognition input device (550) generates recognition confirmation information (551) and transmits it to the control unit (100), and the record output device (570) updates the alarm information log (571) at the same time to clearly record who recognized it and when.

[0201] When the status is updated after the recognition processing and resolution processing are performed in the control unit (100), the user display unit (500) changes the status display of the main alarm and derivative alarm, and if necessary, automatically terminates the auditory notification of the main alarm indicator (510).

[0202] In this iteration process, the user display unit (500) can improve usability in a marine environment by applying feasible UI policies such as a layout strategy that reduces screen occupancy and eye movement distance, a palette that considers color vision deficiencies, a low-light night mode, and a large operation area that can be operated even while wearing gloves.

[0203] Referring to FIG. 11, the communication unit (800) is composed of an information transmitter (810), a command receiver (830), and a network verifier (850), and collects main alarm information (151), awareness confirmation information (551), resolution information (171), etc. generated or managed by the control unit (100) and exchanges them with the control server (S).

[0204] In addition, the context of the communication message is reinforced by referring to the integrated ship information (710) accumulated in the database (700), and the connection status calculated by the network verifier (850) is provided to the control connector (590) of the user display unit (500) along with the external verification command (851), so that the user (U) can immediately determine the communication availability.

[0205] The information transmitter (810) receives the main alarm information (151), awareness confirmation information (551), and resolution information (171) that are updated in real time from the control unit (100) and forms integrated communication information (811).

[0206] The integrated communication information (811) includes at least the alarm identifier and current status, whether the user is aware and the time, and the execution result of the resolution information (171) regarding equipment control, and if necessary, a summary item of the integrated ship information (710) is attached so that the control server (S) can interpret the context of ship operation together.

[0207] The information transmitter (810) receives the network quality at the time of transmission from the network verifier (850) and determines the transmission policy.

[0208] For example, if the delay and loss rates exceed the threshold, only high-priority events are transmitted immediately, while the rest are stored in a buffer and transmitted in batches at regular intervals.

[0209] In sections where the link is broken, batch transmission is performed using timestamps and sequence numbers to ensure the order is guaranteed at the time of reconnection after saving.

[0210] To prevent duplicate reception of the same message, the information transmitter (810) assigns a message-specific identifier and retransmits only the unaccepted items by comparing them with the acceptance response received from the control server (S).

[0211] Through this, the integrated communication information (811) reaches the control server (S) without loss even with changes in the wireless environment, and the control side can track the entire process from the occurrence and recognition of the main alarm to its resolution in chronological order.

[0212] The command receiver (830) is responsible for external command information (831) received from the control server (S).

[0213] The external command information (831) may include items such as, for example, a request for remote recognition confirmation, generation of a test signal for a specific alarm, temporary adjustment of a display policy, and release of equipment control restrictions.

[0214] The command receiver (830) verifies the integrity and authentication of the message and checks the alignment with the integrated ship information (710) to determine whether the command can be applied in the current ship state.

[0215] Refer to the latest connection status provided by the network verifier (850) to check if the transmission path is stable, and if necessary, generate an external verification command (851) to perform retransmission or path switching.

[0216] Applicable external command information (831) is transmitted to the control unit (100) and reflected in the policy of the cognitive processor (160), the resolution processor (170), or the main alarm judgment unit (140).

[0217] If a command is received that conflicts with current operational safety standards, the command receiver (830) suspends the command and sends a rejection response to the control server (S) along with the reason. This ensures that the efficiency of remote measures is maintained without conflicting with safety policies at the ship's site.

[0218] The network verifier (850) continuously calculates quality indicators such as connection status, delay time, loss rate, retransmission rate, and link switching history as a base function of the communication unit (800).

[0219] In a multi-line environment, the priority path and secondary path are managed, and if the path quality drops below a threshold, the line is automatically switched, and the transmission speed and bundle size of the information transmitter (810) are dynamically adjusted to prevent loss during the switching process.

[0220] The status information calculated by the network checker (850) is provided to the control connector (590) of the user display unit (500) to intuitively display to the user (U) whether current control linkage is possible.

[0221] In addition, to verify the execution of a command received from the outside, a verification external command (851) is generated to measure the round-trip delay, and if necessary, session renewal or time synchronization with the control server (S) is performed.

[0222] This process provides the effect of preventing message loss and order distortion even in sections with communication failures.

[0223] The control unit (100) continuously generates main alarm information (151), awareness confirmation information (551), and resolution information (171), and the information transmitter (810) converts this into integrated communication information (811) and transmits it to the control server (S).

[0224] The control server (S) identifies the integrated status of the vessel and issues external command information (831) when necessary. The command receiver (830) checks the validity of the external command information (831) and hands it over to the control unit (100), and at the same time, the network verifier (850) diagnoses the connection quality and transmits the verified external command (851) and status information to the control connector (590) of the user display unit (500) to notify the user (U) of the communication status.

[0225] The database (700) provides context for communication messages through integrated ship information (710), and all transmission and reception records are recorded in the control unit (100) and the database (700) and used for post-audit and cause analysis.

[0226] With this structure, the communication unit (800) increases the reliability of control linkage and connects field measures centered on the main alarm with the reflection of external policies without delay, thereby ensuring the continuity and transparency of alarm processing.

[0227] Referring to FIG. 12, the external sensor unit (900) is a module that detects the environment and navigation conditions around the ship in real time, generates environmental information (730) and navigation information (750) in a common system format, loads this into a database (700), and immediately utilizes it for the judgment of the control unit (100).

[0228] The information provided by the external sensor unit (900) serves as a dynamic basis for reference by the dynamic weighter (120) and the re-judgmenter (180) inside the control unit (100), so the sensitivity and threshold of the main alarm selection and derived alarm classification are automatically adjusted to the actual situation.

[0229] The weather sensor (910) measures weather elements such as wind speed and direction, air pressure and temperature, humidity and visibility, precipitation and thunder and lightning according to the instrument specifications.

[0230] Each measurement is assigned a quality flag indicating whether the sensor is faulty and its reliability, and when there are cases where different sensors measure the same item redundantly, the sensor processor (970) performs cross-verification and a weighted average.

[0231] The marine sensor (930) provides sea conditions such as wave height and wave period, current and surface velocity, water temperature and salinity, and roll and pitch indicating hull motion. Since sea condition indicators directly affect the risk of collision and grounding, the dynamic weighter (120) is used to lower or raise the threshold of the main warning judgment device (140).

[0232] The route sensor (950) is linked with the navigation device to generate route-related data such as the ship's position, course, speed, deviation from the planned route, whether it is an accident-prone area, and surrounding traffic density.

[0233] The information provided by the navigation sensor (950) is used as a basis for increasing alarm sensitivity in sections where steering margin is limited, such as narrow waterways, bridge passages, and pilotage areas.

[0234] The sensor processor (970) is a central processing unit of the external sensor unit (900) that aligns heterogeneous data collected from the weather sensor (910), the marine sensor (930), and the navigation sensor (950) with the system common coordinates and time axis, and unifies the units and resolution.

[0235] The sensor processor (970) assigns a timestamp synchronized with GPS time or onboard reference time, applies filtering such as a moving average or Kalman filter to reduce inter-sample noise, and performs outlier detection to determine abnormal spikes and disconnection conditions.

[0236] When the same item is received from two or more sensors, the sensor with the highest recent reliability is prioritized; however, resilience against single sensor failure is ensured by using adaptive fusion logic that automatically adjusts weighting values ​​if the difference increases within a specific range.

[0237] In extreme situations such as temporary communication interruption or freezing, a short-term interpolation is provided by combining the last reliable sample with linear extrapolation, and immediately upon recovery, it is replaced with the actual measurement value. The interpolation interval is marked with a quality flag to ensure conservative handling in subsequent decisions.

[0238] The results of such preprocessing and fusion are organized into two streams: environmental information (730) and navigation information (750).

[0239] Environmental information (730) includes current and trend values, variability indicators, and quality flags for external environments such as wind, pressure, visibility, wave height, and current. Navigation information (750) contains navigation context such as the vessel's position and course, speed and acceleration, deviation from the planned route, steering mode, danger zone classification, and the nearest approach distance to surrounding vessels.

[0240] The sensor processor (970) continuously stores the two information flows in the database (700) so that they can be used for post-analysis and auditing, and simultaneously streams them to the dynamic weight (120) of the control unit (100) so that they are immediately reflected in the risk level (131) calculated by the risk assessor (130).

[0241] When accumulated in the database (700), the ship identifier, time window, route segment, and quality flag are stored together and subsequently used as a basis for the re-determiner (180) to detect sudden environmental changes or changes in the operation mode.

[0242] The external sensor unit (900) includes a protection design that takes into account the uncertainty of the field environment. Since the sensitivity of the weather sensor (910) and the marine sensor (930) may decrease due to freezing or salt deposition, when the sensor processor (970) detects a specific pattern, it sets an automatic check flag and replaces it with a duplicate sensor value.

[0243] In the event that the position and speed information provided by the navigation sensor (950) spikes momentarily, unrealistic samples are removed using the physical possible range of recent observations and a ship motion model.

[0244] When part of the sensor network is disconnected, environmental information (730) and navigation information (750) are maintained using only the minimum set obtainable from the remaining sensors, and the control unit (100) and user display unit (500) are not overconfident through the quality flag.

[0245] Additionally, the external sensor unit (900) can be designed to have channel redundancy and a power backup path so that it can be restored without data loss even if there is a momentary power drop or wiring disconnection during navigation.

[0246] This operation of the external sensor unit (900) contributes to securing the core dynamism of the main alarm-centered integrated alarm management system.

[0247] For example, in a situation where visibility rapidly deteriorates, waves rise, and the vessel enters a narrow channel, the environmental information (730) and navigation information (750) change immediately, causing the dynamic weighter (120) to increase the weight of the collision and grounding warnings and lower the threshold.

[0248] As a result, even if the main warning judgment device (140) has the same set of warnings, it more easily selects items such as track deviation or radar tracking instability as the main warning in coastal narrow water conditions, and naturally switches to a judgment that prioritizes reduced navigation reliability when the environment is gentle, such as in open ocean navigation.

[0249] Conversely, in sections where blue levels decrease and visibility recovers, the weighting is automatically relaxed to suppress unnecessary increases in alarm sensitivity.

[0250] The external sensor unit (900), composed of a weather sensor (910), a marine sensor (930), a navigation sensor (950), and a sensor processor (970), precisely quantifies the environment surrounding the ship and the navigation context, structures it into environmental information (730) and operational information (750), accumulates this information in a database (700), and simultaneously provides it to the control unit (100) in real time.

[0251] This increases the accuracy of the risk level (131) calculated by the risk assessment device (130) and refines the monitoring function of the re-evaluation device (180), thereby supporting the stable implementation of the alarm control system (1) even under various maritime conditions.

[0253] Although the present invention has been described above with reference to the embodiment(s) illustrated in the drawings, this is merely illustrative, and those skilled in the art will understand that various modifications may be made therefrom, and that all or part of the described embodiment(s) may be optionally combined. Accordingly, the true technical scope of protection of the present invention should be determined by the technical spirit of the appended claims. Explanation of the symbols
