Monitoring system, monitored terminal, notification control method, and program

Abstract

In the case of security alarms, it was difficult to distinguish between false alarms caused by user error and genuine emergencies, making it difficult for parents to appropriately assess the urgency of the situation and take initial action. [Solution] A monitoring system including a monitored terminal, a management server, and a guardian terminal. The monitored terminal determines whether the alarm sounding of the security buzzer was stopped by an intentional operation by the user, such as pushing back a pin, or whether it was stopped automatically after a predetermined time had elapsed. This determination result, the stop type information, is transmitted to the management server. Based on the stop type information, the management server generates a low-urgency notification if the alarm was stopped intentionally by the user, and a high-urgency notification if it was stopped automatically. The guardian terminal receives and displays the notification information, whose content and display style have been changed according to the urgency level. This allows the guardian to intuitively grasp the level of urgency and take appropriate action.

Modes for Carrying Out the Invention

[0009] 1. System Overview 1.1 Basic Concept In addition to the conventional position notification function, the monitoring system 1 of the present invention has a mechanism for evaluating the authenticity of an emergency by combining an automatic discrimination function for the buzzer stop mode. When a child intentionally stops the buzzer (high possibility of false alarm) and when it stops automatically over time (high possibility of a real emergency) are automatically identified, and the notification level to the protector is adaptively controlled.

[0010] As an example of utilization on the elementary school commuting route, when a child encounters a suspicious person, the buzzer is sounded. In a real dangerous situation, since the child has no time to perform a buzzer stop operation, it stops automatically, and the system determines that it is a high emergency level and immediately reports to the protector, school, and police. On the other hand, in the case of mischief or misoperation, since the child himself / herself presses the pin back to stop, the system determines that it is a low emergency level and only sends a gentle confirmation notice to the protector.

[0011] 1.2 Term Definitions [[ID=*10]]The definitions of the main terms used in this specification are shown below. "Stop mode" is an inclusive concept that includes all information related to the stop of the alarm sound, including the type of stop method, the elapsed time until stop, the details of the stop operation, the environmental and biometric information at the time of stop, etc. "Emergency level" is an index expressing the degree of urgency, and means a stepwise or continuous urgency evaluation regardless of the expression form such as discrete values (0, 1, 2, etc.), continuous values (0 - 100, etc.), category values (high, medium, low, etc.), or other expression forms.

[0012] "First stop means" is a general term for stop functions executed by the intentional and active operation of the user, including stop operations accompanied by the explicit intention of the user, such as physical operations (buttons, pins, touches), voice operations, gesture operations, biometric authentication operations, composite operations, etc. "Second stop means" is a general term for stop functions not accompanied by the active operation of the user, including automatic stop due to elapsed time, automatic stop due to battery depletion, remote stop by system control, safety stop by abnormality detection, etc.

[0013] "Management server" is a general term for processing entities responsible for the control functions of the monitoring system, and does not depend on the physical implementation form, such as independent server devices, distributed processing systems, or layered implementations of cloud, edge, and terminals. "Notification control unit" is a functional entity that performs stepwise notification control according to the urgency level, and does not depend on the implementation method, such as a processing unit within a single device, a distributed processing function spanning multiple devices, or a cooperative control system. "Distributed processing architecture" refers to a system configuration in which system functions are distributed among multiple processing entities, and the overall function is realized through cooperative operation.

[0014] 2. System Configuration 2.1 Overall Structure As shown in Figure 1, the monitoring system 1 consists of a monitored terminal 10, a guardian terminal 20, a management server 30, and a network 40. The monitored terminal 10 is carried by the person being monitored (mainly a child), the guardian terminal 20 is the guardian's smartphone or tablet, and the management server 30 is implemented as a group of servers on the cloud.

[0015] 2.2 Role of Each Device The monitored terminal 10 is responsible for acquiring GPS location information, controlling buzzer activation, determining the type of stoppage, and evaluating the urgency level. The guardian terminal 20 supports the guardian in making appropriate decisions by displaying differentiated UI according to the urgency level. The management server 30 aggregates information from multiple monitored terminals and provides notification control, history management, and statistical analysis functions. However, this functional arrangement is just one example, and it is also possible to distribute the notification control function of the management server 30 between the monitored terminal 10 and the guardian terminal 20. In this case, the monitored terminal 10 is responsible for the notification determination function, and the guardian terminal 20 is responsible for the notification execution function, and the cooperation between the two achieves functionality equivalent to a centralized server.

[0016] 2.3 Communication Architecture The monitored terminal 10 is constantly connected to the management server 30 via an LTE line, enabling real-time information transmission in emergencies. The guardian terminal 20 receives push notifications from the management server 30 and displays differentiated information according to the urgency level. WebSocket and HTTPS communication protocols are used, prioritizing low latency.

[0017] It should be noted that the arrangement and implementation of each component in the monitoring system of the present invention are not limited to the embodiments described above. The functions of the management server 30 can be implemented in a physically independent server device, or they can be distributed and implemented on the monitored terminal 10 and the guardian terminal 20. For example, a distributed system configuration in which the notification control unit functions of the management server 30 are divided and implemented in a local control unit 10a in the monitored terminal 10 and a receiving control unit 20a in the guardian terminal 20, and direct communication is performed between the two terminals, is also within the scope of the present invention.

[0018] As a concrete example of a distributed implementation, the monitored terminal 10 determines the type of shutdown and the urgency level, then transmits this information to the guardian terminal 20 via direct communication means such as 5G communication, Wi-Fi Direct, or Bluetooth. The receiving control function within the guardian terminal 20 then modifies the notification content according to the urgency level. In this case, the local control function within the monitored terminal 10 and the receiving control function within the guardian terminal 20 cooperate to achieve notification control functionality equivalent to that of a centralized management server. The important thing is that urgency determination based on the shutdown type and stepwise notification control according to the result are realized, regardless of the physical arrangement of these functions.

[0019] 3. Hardware Configuration 3.1 Hardware configuration of the monitored terminal As shown in Figure 2, the monitored terminal 10 includes a CPU 11, memory 12, storage device 13, GPS receiver 14, communication interface 15, alarm unit 16, operation unit 17, and battery 18.

[0020] The CPU 11 is a low-power ARM Cortex-M microprocessor, responsible for executing the urgency assessment algorithm and controlling each function. The memory 12 is an SRAM area of ​​512KB or more, used as a working area during program execution. The storage device 13 is a flash memory of 16MB or more, which non-volatilely stores control programs, configuration information, and history data.

[0021] The GPS receiver 14 receives satellite signals from the Global Positioning System (GPS) and obtains the latitude and longitude coordinates of the current location. To improve positional accuracy, the GPS receiver 14 also supports the Quasi-Zenith Satellite System (QZSS), improving positioning accuracy in urban areas and near indoors. The acquired location information is used by the emergency assessment unit 114 to determine safe areas and dangerous areas.

[0022] The alarm unit 16 includes a loud buzzer with a volume of 120 dB or more and a volume control circuit. The volume control is adjusted in stages according to the surrounding environment, suppressing the volume in quiet environments such as schools and libraries, and increasing the volume on busy roads. The operation unit 17 is equipped with a pull pin for activating the buzzer, a push button for stopping it, and a small display.

[0023] Battery 18, powered by a lithium-ion battery, provides over a week of continuous operation. Its power-saving design optimizes battery life by operating in sleep mode under normal circumstances and only switching to active mode when the buzzer sounds.

[0024] The communication interface 15 provides communication with the management server 30 using an LTE line, as well as short-range Bluetooth communication functionality. For LTE communication, the Cat-M1 or NB-IoT standard is adopted to achieve long-distance communication with low power consumption.

[0025] The monitored terminal 10 is equipped with a set of enhanced sensors for high-precision situation recognition, in addition to its basic configuration. The microphone 19 constantly monitors the ambient noise level and detects abnormal environmental sounds (screams, collisions, explosions, etc.). A small, high-sensitivity microphone implemented using MEMS technology analyzes broadband acoustics from 20Hz to 20kHz, which is used in the environmental considerations assessment by the emergency severity assessment unit 114.

[0026] The biosensor 21 is a multimodal biometric information acquisition device that integrates a heart rate sensor, a body temperature sensor, and a 3-axis accelerometer. The heart rate sensor monitors heart rate in the range of 60-180 bpm using the photoplethysmography (PPG) method, and the body temperature sensor measures surface temperature with an accuracy of ±0.1°C using the infrared method. The accelerometer detects terminal movement in the range of ±16G and recognizes physical danger conditions such as falls, impacts, and abnormal vibrations. This biometric and physical information, combined with information on the type of stoppage, contributes to improving the accuracy of emergency determination.

[0027] Security module 22 includes an AES256 encryption engine, an elliptic curve cryptography (ECC) processing unit, a random number generator, and a secure key management area. All communication data is encrypted by this module to prevent eavesdropping and tampering by third parties. In particular, highly confidential data such as shutdown information and urgency levels are protected by end-to-end encryption, maintaining security even during distributed processing.

[0028] (Exterior configuration) As shown in Figure 11, a ring-shaped pull tab 170a is provided at one end (top) of the housing 174 of the monitored terminal 10, which activates a security buzzer when pulled. A touch-sensitive display 17b is located on the first surface (front) of the housing. Operation buttons 17a used for recording and other operations are provided on the side of the housing, positioned so that users can naturally press them with their thumbs while gripping the housing, even when it is fixed to the shoulder strap of a school bag. Furthermore, a speaker 16a and an adjacent microphone 19a are located above the display 17b on the first surface, enabling efficient sound output and voice input. An LED 23 is provided near the display for notifications such as message reception. Charging can be performed via a charging port (Type-C). This configuration achieves both (i) a clear layout of the control system and (ii) quick gripping and operation in emergencies, and (iii) improved visibility and audibility of display and audio input / output.

[0029] The display 17b is implemented as part of the operation unit 17 (see Figure 2) and is used for displaying the terminal status and detecting touch input. The ring-shaped pull tab, thumb operation via shoulder strap fixation, and Type-C charging shown in Figure 11 are implementation examples that align with the requirements of the monitored terminal 10. For the basic ringing time, an implementation with an initial value of 30 seconds is envisioned for operational purposes.

[0030] Figure 13 is a reference diagram showing the mounting state of the monitoring terminal 10 according to this embodiment. The monitoring terminal 10 is primarily intended to be used by being fixed to the shoulder strap of a school bag. As shown in Figure 13, the terminal is ergonomically positioned so that the user's thumb can reach the operation button 17a on the side of the casing when the user naturally holds the terminal. This allows the user to perform operations such as recording voice messages without stress. Even in this mounting state, the ring-shaped pull tab 170a is kept in a position that allows for immediate access in an emergency.

[0031] 3.2 Hardware configuration of the management server As shown in Figure 3, the management server 30 includes a CPU 31, memory 32, storage device 33, and communication interface 34. The CPU 31 is a multi-core processor that enables parallel processing and supports simultaneous access from multiple monitored terminals. The memory 32 supports high-speed data processing with large-capacity RAM, and the storage device 33 acts as a database storage, persistently storing history information and configuration data of monitored terminals. The management server may further include a load balancer 35, an AI processing engine 36, an external collaboration interface 37, and an edge processing delegation function 38.

[0032] 3.3 Pull-type buzzer mechanism and alternative implementations As shown in Figure 9, the pull-type buzzer mechanism has a cross-sectional configuration as its basic mechanism and takes on three operating states: normal state (state A), sounding state (state B), and stopped state (state C). The state change of the microswitch 173 in each state clearly distinguishes between the first and second stopping means. Furthermore, as shown in the same figure, various stopping operation means such as button type, touch type, voice type, gesture type, and biometric type can be used as alternative implementation examples, and it can also be applied to different wearing forms such as wristwatch type, pendant type, and shoe type. As shown in Figure 9, an example of a pull-type buzzer mechanism consists of a pin 170, a pin holder 171, a spring 172, a microswitch 173, and a housing 174. In the normal state (state A), the pin 170 is inserted and the microswitch 173 is in the ON state. When the user pulls the pin 170 (state B), the microswitch 173 transitions to the OFF state, and the alarm unit 16 detects this and sounds an alarm. Subsequently, if the user intentionally pushes the pin 170 back to its original position (state C), the microswitch 173 returns to the ON state and the alarm stops. This stop due to explicit operation by the user corresponds to the "first stopping means". On the other hand, if a predetermined time has elapsed without the pin 170 being pushed back, the alarm automatically stops due to the timer function of the alarm control unit 111. This automatic stop due to the passage of time corresponds to the "second stopping means". The stopping method determination unit 113 determines which means were used to stop the alarm based on the state transition of the microswitch and the state of the timer.

[0033] In this specification, "first stopping means" is a general term for means of stopping the alarm sound through intentional operation by the user, and does not specify the concrete implementation form. Typical implementation examples of the first stopping means include stopping operations that combine a pull-back operation of a pin, a button-type press operation, a touch operation on a touch-type device, a voice command instruction using a voice-type device, a gesture operation using a gesture-type device, and a biometric authentication operation using a biometric device, as shown in Figure 9.

[0034] Furthermore, the first stopping means is not limited to a single operating means, but may be a complex stopping means that combines multiple operations. For example, various operating systems can be adopted that ensure reliable intentional stopping while preventing accidental operation, such as a two-step operation of pressing and holding a button for 3 seconds or more followed by pushing the pin back, a touch operation in a specific pattern, or a button operation simultaneously with speaking a pre-registered voice password.

[0035] 4. Functional Configuration 4.1 Functional Block Configuration of the Monitoring Terminal As shown in Figure 4, the functional configuration of the monitored terminal 10 includes an alarm control unit 111, a location information acquisition unit 112, a stop type determination unit 113, an emergency level evaluation unit 114, and a communication control unit 115. In addition to these basic functional blocks, it can be equipped with enhanced functional blocks such as a local notification determination unit 116, an environment recognition unit 117, a situation prediction unit 118, and a security control unit 119. These functional blocks are implemented as program modules executed on the CPU 11.

[0036] The alarm control unit 111 is responsible for controlling the start and stop of the alarm sound, controlling the volume level, and managing the alarm duration. For volume control, it is automatically adjusted in three stages according to the environmental characteristics of the current location, for example, 70 dB in schools, 90 dB in residential areas, and 120 dB on busy roads.

[0037] The location information acquisition unit 112 performs periodic acquisition of GPS coordinates, evaluation of positioning accuracy, and management of location history. Normally, location acquisition is performed at 5-minute intervals, but when the buzzer sounds, it switches to continuous positioning at 1-second intervals to record detailed movement trajectories in emergencies.

[0038] The assessment of urgency is not limited to post-event determination after the buzzer stops. Assessment is possible at any point in time, such as pre-event prediction before the buzzer sounds, continuous evaluation while the buzzer is sounding, and post-event analysis after it stops. In a pre-predictive system, the urgency is assessed in advance by detecting signs of a dangerous situation, and the buzzer output level and notification content are controlled based on the results. In this case as well, the essential technological concept of the present invention, which is stepwise control based on situation assessment, is realized.

[0039] Figure 5 shows a detailed flowchart of the urgency determination process in this embodiment. This process is a series of determination, evaluation, and notification control processes executed by the CPU 11 of the monitored terminal 10.

[0040] Step S101: Buzzer starts sounding When the user presses the emergency button or pulls out the pin, the alarm unit 12 starts outputting a buzzer sound. At the same time, the GPS receiver 14 starts positioning and various sensors start continuous monitoring.

[0041] Step S102: User operation detection and determination (Branch A) The stop mode determination unit 113 monitors for explicit stop operations by the user (button press, pin insertion, touch panel operation, etc.) while the buzzer is sounding. If an operation is detected (YES), the system proceeds to the explicit stop route using the second stop means; if no operation is detected (NO), the system proceeds to the time elapsed determination (branch B).

[0042] Step S103: Second stopping means determination (explicit stopping) If an explicit stop operation by the user is detected, the stop type determination unit 113 records the type of operation (button, pin, touch, etc.), the time of the operation, and the duration of the alarm. This information is transmitted to the urgency evaluation unit 114 as stop type information.

[0043] Step S104: Determination of elapsed time (Branch B) If no explicit operation is detected, the system monitors for a predetermined time T. If the predetermined time has elapsed (YES), the system proceeds to the automatic stop route by the first stop means; otherwise, monitoring continues. The predetermined time T is set variably based on location information, time of day, past behavior patterns, etc.

[0044] Step S105: First stopping means determination (automatic stop) If the system automatically stops after a predetermined period of time, the stop type determination unit 113 records the time of the automatic stop, the duration of the alarm, and environmental information at the time of the stop. An automatic stop suggests that the user may be in a situation where operation is difficult, and therefore serves as evidence of a high level of urgency.

[0045] Step S106: Urgency assessment process The urgency assessment unit 114 uses the stopping method information as the main factor and performs the following correction processing: (1) Calculation of base score: Set a base score of 70 points for the first stopping method (automatic stop) and a base score of 30 points for the second stopping method (explicit stop); (2) Position correction: +20 points for dangerous areas and -10 points for safe areas; (3) Time correction: +15 points for nighttime and during school commuting hours; (4) History correction: -5 to +10 points depending on the frequency of past false alarms.

[0046] Step S107: Final Judgment The urgency level is determined based on the corrected overall score. A score of 80 or higher indicates high urgency (Level 2), 50-79 points indicates moderate urgency (Level 1), and 49 points or lower indicates low urgency (Level 0). Continuous values ​​(0-100) can also be output.

[0047] Step S108: Notification Control Based on the determined urgency level, the notification method is selected. In the centralized system, integrated notification distribution is performed via the management server 30, while in the distributed system, direct notifications are sent from the monitored terminal 10 to the guardian terminal 20. The selection of the notification method is dynamically determined based on the communication status, urgency level, and pre-configured settings. This workflow automatically determines whether an emergency has occurred based on objective facts such as how the buzzer stopped, enabling appropriate initial response.

[0048] The stop mode determination unit 113 is a core function of the present invention, and it analyzes the situation when the alarm sound stops and generates stop mode information. Specifically, it distinguishes between an explicit stop operation by the user (first stop means) and an automatic stop due to the passage of time (second stop means), and records in detail the circumstances leading to the stop.

[0049] The determination of the stopping method in the stopping method determination unit 113 is achieved by one of the following multiple implementation methods. In the first implementation method, the alarm start time and stopping time are recorded, and if the stopping time has reached a predetermined time (e.g., 5 minutes), it is determined to be the second stopping method, and if it has not yet reached the predetermined time, it is determined to be the first stopping method. In the second implementation method, the presence or absence of a stopping operation is directly detected, and the stopping method is determined based on the presence or absence of a detection signal for a stopping operation by the user. In the third implementation method, the change pattern of the sensor state (accelerometer, contact sensor, position sensor, etc.) at the time of stopping is analyzed, and the difference between an active stopping operation and a passive stopping operation is determined.

[0050] More specifically, the stop type determination unit 113 executes the following determination flow when a stop event occurs. First, it checks the elapsed time since the alarm started, and if the preset automatic stop time has been reached, it determines that the stop was performed by the second stop means. If the elapsed time has not reached the automatic stop time, it checks for the presence or absence of an input signal from an operation detection sensor (button, touch panel, pull-type pin, etc.), and if an input signal is detected, it determines that the stop was performed by the first stop means. This determination result is recorded as stop type information along with a timestamp and transmitted to the urgency evaluation unit 114.

[0051] Furthermore, the generation of stopping method information is not limited to the direct determination of the stopping method. The duration of the alarm sound from the start of output to the stop is also important information that indirectly indicates the stopping method. Specifically, if the alarm stops before a predetermined time has elapsed, it is highly likely that the alarm was stopped by the first stopping means, and if the alarm continues to sound until the predetermined time has elapsed, it can be estimated that the alarm was stopped by the second stopping means. Therefore, measuring, recording, and evaluating the duration of the alarm sound is also included as one embodiment of stopping method determination in this invention.

[0052] The local notification determination unit 116 performs a determination in the distributed processing system regarding when the monitored terminal 10 should directly notify the guardian terminal 20. If communication with the management server 30 is unstable or if the urgency is extremely high, it performs direct notification control using the P2P communication path.

[0053] The environmental recognition unit 117 integrates noise level information acquired from the microphone 19 with heart rate, body temperature, and acceleration information from the biosensor 21 to analyze the environmental background of the emergency situation. This environmental information is used in the correction process by the urgency assessment unit 114.

[0054] The situation prediction unit 118 performs a pre-risk assessment function, detecting signs before the buzzer sounds. Through a combined analysis of location history, behavior patterns, time of day, etc., it pre-evaluates the likelihood of an emergency occurring and pre-adjusts the alarm control.

[0055] The security control unit 119 provides security functions that integrate the encryption engine, authentication processing, and secure key management. In particular, highly confidential data such as shutdown type information and urgency levels are protected by AES256 encryption, ensuring end-to-end confidentiality even during distributed processing.

[0056] (Variable setting for predetermined time) As shown in Figure 12, the second stopping means (automatic stopping) of this embodiment uses a predetermined time T that is variable depending on the situation, rather than a fixed value. The processor (CPU 11 of the monitoring terminal 10) acquires the following input information: (a) current location information (GPS receiver 14), (b) behavior pattern information (movement history based on location history table 710), (c) time period information, and (d) area information DB (classification of school / public facility / dangerous area).

[0057] The processor makes the following decisions based on the input information: (1) Area determination: If within a dangerous area, the time is extended; if within a school or public facility, the time is shortened. (2) Behavioral pattern determination: If the degree of deviation from the normal behavioral pattern exceeds a threshold, the time is extended. (3) Time of day determination: If it is nighttime or a holiday, the time is extended. Based on these determination results, the final predetermined time T is determined by adding or subtracting from the basic alarm time T0 (e.g., 30 seconds) using the following formula: T = clamp(T0 + Δ Area + Δ Pattern + Δ Time of Day, Tmin, Tmax). Here, specific examples of each correction value are as follows. • Δ Area: +60 seconds inside dangerous areas, -15 seconds inside schools, -10 seconds inside public facilities • Δ Pattern: High degree of behavioral deviation +30 seconds, within normal range ±0 seconds • Time zone: Nighttime (10pm-6am) +45 seconds, Holidays +20 seconds, Weekday daytime ±0 seconds Tmin and Tmax are the lower and upper limits, respectively (e.g., 10 seconds to 300 seconds). This variable control allows the alarm duration, which is normally 30 seconds, to be dynamically adjusted within a range of 10 to 300 seconds depending on the situation.

[0058] The above variable settings embody the technical concepts described in claims 4, 8 to 11 (variable settings according to location, behavior, and time of day; extension in dangerous areas; shortening in schools / public facilities; extension in case of behavioral deviation; extension at night / holidays), and contribute to the appropriateness of notifications, reduction of false alarms, and improvement of safety.

[0059] The urgency assessment unit 114 determines the urgency level (3 levels from 0 to 2) through a multidimensional evaluation using stoppage pattern information as the primary factor and location information, time information, and history information as secondary factors. The weighting of the evaluation algorithm is optimized through statistical analysis based on the operational experience of a large-scale monitoring system. For example, the weighting is set at 70% for stoppage pattern, 15% for location information, 10% for time information, and 5% for history information. However, these weighting coefficients can be dynamically adjusted according to the user's age, behavioral patterns, regional characteristics, etc.

[0060] The specific method for determining the weighting coefficients is explained below. The weighting of the stopping method (70%) is based on the finding from statistical analysis of past emergency cases that in true emergencies, more than 90% of cases end with the second stopping method (automatic stopping), and in false alarms, more than 80% end with the first stopping method (explicit stopping). The weighting of location information (15%) adjusts the urgency by +20% in dangerous areas (construction sites, busy areas, etc.) and by -10% in safe areas (schools, homes, etc.). The weighting of time information (10%) adjusts the urgency by +15% when an event occurs at night (10pm-6am) or during school commuting hours. The weighting of history information (5%) adjusts the urgency within a range of -5% to +10% depending on the frequency of false alarms in the past week.

[0061] The specific criteria for determining the urgency level are as follows: A total score of 80 points or higher is classified as high urgency (level 2), 50-79 points as moderate urgency (level 1), and 49 points or lower as low urgency (level 0). The base score for the second stopping measure is 70 points, and for the first stopping measure it is 30 points. Various correction coefficients are added to these to calculate the final score. This judgment algorithm is continuously improved through machine learning and optimized for each region and user group.

[0062] The communication control unit 115 sends notification information, including the determined urgency level, to the management server 30. In communication control, the transmission priority is changed according to the urgency level; for high urgency, transmission is performed immediately, and for low urgency, transmission is performed after other processing is completed.

[0063] The specific data structure of the stop type information includes a stop method identifier (AUTO_STOP, MANUAL_STOP, etc.), stop time, type of stop operation (BUTTON_PRESS, PIN_PUSH, TOUCH_OPERATION, etc.), elapsed time until stop, and terminal status information at the time of stop (location, acceleration, battery level, etc.). This information is structured in JSON or XML format and used for multidimensional analysis in the urgency assessment unit 114.

[0064] The local notification determination unit 116 is a control module that performs notification determination within the monitored terminal 10 in a distributed system configuration. Based on the urgency level received from the urgency assessment unit 114, it determines whether direct communication with the guardian terminal 20 is necessary, the priority of the transmitted data, the encryption level, and the retransmission control parameters.

[0065] The environmental recognition unit 117 integrates and processes information from the microphone 19 and biosensor 21 to comprehensively recognize the environmental conditions around the terminal. In acoustic analysis, it analyzes the frequency spectrum using FFT processing to classify and identify human voices, vehicle sounds, etc. In bioinformation analysis, it evaluates the psychological stress state using heart rate variability (HRV) analysis.

[0066] The situation prediction unit 118 performs advance prediction of dangerous situations using a machine learning algorithm. It uses past location history, behavior patterns, time information, and environmental data as features to perform time-series prediction using an LSTM (Long Short-Term Memory) network. The prediction results are used to determine whether to activate the pre-warning mode.

[0067] The security control unit 119 works in conjunction with the security module 22 to centrally manage the security policy for the entire system. It performs tasks such as controlling the encryption and decryption of communication data, generating and verifying digital signatures, authentication processing, and session management.

[0068] 4.2 Details of the urgency assessment algorithm As shown in Figure 10, the urgency assessment engine 800 performs a multidimensional assessment that takes into account the following auxiliary information in addition to the basic stop type information 802.

[0069] Location information 803 determines whether the current location is a safe area such as a school or home, or a dangerous area such as a busy commercial district or construction site. Automatic stopping in a dangerous area is given a higher urgency rating. Time information 804 considers the temporal context, such as school commuting hours, nighttime, and holidays, and events occurring during high-risk times are given a higher urgency rating.

[0070] Historical information 805 is used to analyze past false alarm patterns, normal routes, and duration of stay using machine learning, and the urgency level is adjusted according to the degree of deviation from the normal pattern. Furthermore, extended input elements such as ambient sound information 806, biometric information 807, movement information 808, and communication information 809 are also taken into consideration, and the AI ​​judgment support 801 determines the overall urgency level 810.

[0071] A detailed implementation example of time-based judgment is described below. In this modified example, the stop type determination unit 113 continuously monitors the elapsed time since the alarm started and applies the following determination logic: Stop within 1 minute of the alarm starting: 30 points of urgency, stop between 1 and 3 minutes: 50 points of urgency, stop between 3 and 5 minutes: 70 points of urgency, automatic stop after 5 minutes: 90 points of urgency. This time-based evaluation is also a form of stop type determination that distinguishes between intentional stops by the user (short duration) and continuous alarms due to circumstances (long duration).

[0072] The integrated processing algorithm adds weighted correction values ​​from each extension element to the base judgment score (70% weighted based on the type of stop). Final score = Base score + (Position correction × 0.15) + (Time correction × 0.10) + (History correction × 0.05) + (Ambient sound correction × 0.05) + (Biological correction × 0.08) + (Movement correction × 0.04) + (Communication correction × 0.03). A final determination is made based on this integrated score: high urgency if 80 or higher, medium urgency if 50-79, and low urgency if 49 or lower.

[0073] 5. Data Structure 5.1 Database Design As shown in Figure 7, the system consists of five main tables: terminal information table 700, location history table 710, emergency log table 720, stop type details table 730, and AI learning data table 740.

[0074] The terminal information table 700 manages the basic information, current location, battery level, and latest urgency level of each monitored terminal. The location history table 710 stores historical data on time, location coordinates, movement speed, and duration of stay. The emergency log table 720 records the time of buzzer sounding, the type of stoppage, the assessed urgency, and the response result.

[0075] The terminal ID is a 16-digit alphanumeric unique identifier, and the location coordinates are recorded in WGS84 format as latitude and longitude, up to 6 decimal places. The urgency level is stored as an integer value from 0 to 2, and the timestamp is standardized in UTC format.

[0076] The Stop Mode Details Table 730 stores detailed stop-related information in a structured format. The Stop Type field records classification codes such as "AUTO_TIMEOUT" and "MANUAL_BUTTON," and the Duration field stores the ringing time in seconds. The Operation Type field records specific operation methods such as "Press and hold for 3 seconds."

[0077] The AI ​​learning data table 740 manages the dataset for the continuous improvement of the machine learning model. The feature field stores information such as the type of stoppage, location, and time in a normalized vector format, while the training data field records the presence or absence of an actual emergency (0: false alarm, 1: true emergency).

[0078] 6. User Interface 6.1 Example of screen display on parent / guardian device As shown in Figures 6A to 6D, the display screen of the parent terminal 20 is differentiated according to the urgency level. In the normal screen 610 of Figure 6A, the map display 611 and the current location icon 612 are displayed with a green background. In the low-urgency screen 620 of Figure 6B, a warning message 621 and a status confirmation button 623 are displayed with a yellow background. In the high-urgency screen 630 of Figure 6C, an emergency warning message 631 and an emergency contact button 633 are displayed in large font with a red background. In addition, as shown in Figure 6D, the urgency level can also be displayed as a continuous value progress bar 641 or a numerical value 643.

[0079] Figures 14A and 14B show specific examples of notification content displayed on the parent terminal 20 depending on how the buzzer stops. As shown in Figure 14A, if the buzzer stops automatically after a predetermined time has elapsed (second stopping method), the system determines that there is a high probability that the user is unable to operate the device. In this case, along with a strong warning message 631 such as "Possible Emergency," the system clearly states that the buzzer has "automatically stopped" and displays UI elements such as an emergency contact button 633 to encourage immediate action. On the other hand, as shown in Figure 14B, if the buzzer is stopped by user operation (first stopping method), the system determines that there is a high probability of user error. In this case, along with a milder warning message 621 such as "Operation Confirmation," the system notifies that the buzzer has been "stopped" by operation and displays UI elements such as a status confirmation button 623 to encourage confirmation. By clearly distinguishing the notification content according to the stopping method in this way, parents can intuitively grasp the urgency of the situation and take appropriate initial action.

[0080] 6.2 Audio and Visual Feedback The type and volume of notification sounds are differentiated according to the urgency level. A light chime is used for low urgency, a warning sound for medium urgency, and a continuous alarm sound for high urgency. In addition, screen brightness and vibration intensity are adjusted in conjunction with the urgency level.

[0081] 6.3 Specific Examples of Implementation Screens As shown in Figure 15, the application implementation on the parent terminal 20 includes a function to visually display the results of the stop method determination. On the map screen, the movement history of the monitored terminal is displayed with timestamps (e.g., 17:50, 17:45, 17:43), and the stop method is clearly indicated for each location marker. For example, a green "manual stop" label is displayed for stops made by the first stop method, and an orange "automatic stop" label is displayed for stops made by the second stop method.

[0082] The user status panel at the bottom of the screen displays the battery level along with the latest stop method information. "First stop method" indicates stopping the device through intentional operation by the user, while "Second stop method" indicates automatic stopping due to the passage of time. The legend area in the lower right corner of the screen provides color-coded explanations (green: manual, orange: automatic) and supplementary explanations, designed to allow parents to intuitively understand the situation.

[0083] This implementation allows parents to see at a glance how their child stopped the buzzer on a map, enabling them to visually grasp important information that forms the basis for determining the level of urgency. In particular, being able to view the stopping history at multiple locations in chronological order allows for a comprehensive assessment of the relationship between behavioral patterns and emergencies.

[0084] 7. Processing Sequence 7.1 Handling Flow in the Event of an Emergency As shown in Figures 8A and 8B, there are two patterns for emergency processing sequences: centralized and distributed. In the centralized type shown in Figure 8A, the monitored terminal 10, the management server 30, and the guardian terminal 20 work together to process the data, as shown in steps M1-M10. In the distributed processing (P2P) type shown in Figure 8B, the local control unit 10a of the monitored terminal 10 and the receiving control unit 20a of the guardian terminal 20 work in coordination, as shown in steps P1-P5.

[0085] 7.2 Notification Delivery Process Steps M5-M7: The notification control unit of the management server 30 determines the notification recipient and content according to the urgency level and delivers the notification to the parent terminal 20. In the case of high urgency, in addition to immediate notification to the parent terminal, an automatic notification is also sent to pre-configured emergency contacts.

[0086] In distributed processing (P2P), as shown in steps P1-P5, the local control unit 10a of the monitored terminal 10 and the receiving control unit 20a of the guardian terminal 20 work in coordination. In the P1 (direct communication establishment) phase, a stable communication path is dynamically selected between the two terminals. In the P2 (direct transmission of urgency information) phase, the urgency information is transmitted directly as structured data.

[0087] In P3 (Local Control Execution), transmission priority control, etc., is applied within the monitored terminal 10. In P4 (Reception Control Execution), the guardian terminal 20 performs decoding, verification, and generation of UI display instructions for the received data. In P5 (Response Confirmation), the guardian terminal 20 sends a confirmation of receipt and response status back to the monitored terminal 10.

[0088] 8. Extensions and Variations The above embodiments are examples for illustrating the present invention, and the present invention is not limited to these embodiments. Within the scope of the present invention, it is possible to combine the components of each embodiment as appropriate or to replace some of them with other components. Furthermore, for example, the following variations are conceivable, and it is possible to combine the components of these variations as appropriate.

[0089] (Example 1: Estimation of stopping behavior information) In this embodiment, a configuration has been described in which the monitored terminal 10 generates information that clearly identifies the stopping method and transmits it to the management server 30, but the embodiment is not limited to this. For example, the monitored terminal 10 may transmit only the buzzer start time and stop time to the management server 30. In this case, the management server 30 can calculate the elapsed time from the start of sounding to the stop and estimate (determine) whether the stop was performed by the first stopping means or the second stopping means based on whether the elapsed time matches a predetermined time (for example, a variablely set automatic stop time T*). Thus, the information indicating the stopping method includes not only information explicitly generated on the terminal side, but also information indirectly derived or estimated from other information on the server side.

[0090] (Variation 2: Change of the entity responsible for urgency assessment) In this embodiment, a configuration in which the monitored terminal 10 determines the urgency level has been mainly described, but the processing entity for urgency evaluation can be flexibly changed. For example, the monitored terminal 10 may transmit only raw data such as stop status information and location information to the management server 30, and the management server 30 may perform all functions equivalent to the urgency evaluation unit 114. This configuration has the advantage of reducing the processing load on the terminal side and allowing more advanced and complex evaluation algorithms to be executed on the server side. Conversely, a completely distributed configuration in which all urgency evaluation and notification content determination are performed within the monitored terminal 10 and directly notified to the guardian terminal 20 is also within the scope of the present invention.

[0091] (Example 3: Gradual refinement of notification information) In this embodiment, a configuration has been described in which the notification content is changed according to the urgency level, but notifications are not limited to being completed in one go. For example, when the second stop means (automatic stop) is detected, the highest level of emergency notification ("Emergency!") is first sent to the guardian terminal 20. After that, the management server 30 analyzes the surrounding audio data and vital data collected by the microphone 19 and biosensor 21 of the monitored terminal 10, and may then send additional information indicating a more detailed situation, such as "Screaming detected nearby" or "Heart rate is rapidly increasing," in stages. This allows the guardian to understand the progression of the situation in more detail.

[0092] (Example 4: Continuous improvement through machine learning) The management server 30 statistically analyzes historical data from multiple monitored terminals to learn the relationship between the type of shutdown and actual emergencies. For example, it provides a function for parents to input feedback such as "it was a false alarm" in response to a notification, and this feedback data is used as training data. Based on these learning results, the parameters of the emergency assessment algorithm (for example, the weighting coefficient of the assessment score and the initial value T0 of a predetermined time) can be dynamically adjusted to continuously improve the accuracy of the assessment for each user or region.

[0093] Operation buttons can be physical buttons independently positioned on the sides or surface of the casing, or they can be implemented as touch-sensitive buttons integrated with the display. In the case of display-integrated buttons, they function as soft buttons displayed in a specific area of ​​the display, providing a haptic feedback function that gives the user the feeling of pressing a physical button while maintaining the same feel as touch operation. This ensures reliable operation even in emergencies, while achieving both miniaturization and usability of the device.

[0094] The notification system includes multiple recipients, including parents' devices, school officials, police stations, fire departments, security companies, and other public or emergency response organizations. This allows for simultaneous notification to multiple relevant organizations capable of rapid rescue and response in high-urgency situations, not just parents. Conversely, in low-urgency situations, notifications are limited to parents, reducing unnecessary burdens on relevant organizations and enabling an efficient emergency response system.

[0095] The display of notification information on the parent's device includes not only text messages but also a visual display that plots the location of the buzzer sound on a map. As shown in Figure 6E, the map display on the parent's device clearly shows the location of the emergency with a black pin and the current location of the person being monitored with a white pin. This allows parents to intuitively understand the relationship between the location of the emergency and their current location, enabling them to take swift rescue action. In addition, quick action buttons such as "Go to the scene," "Contact school," and "Call police" are placed in conjunction with the map display, allowing parents to immediately select the appropriate response according to the situation.

[0096] As shown in Figure 16, the automatic stop time setting screen may provide a function that allows users to directly set arbitrary values. Two setting methods are available: setting a uniform time for all areas and setting individual times for each location. In location-specific settings, it is possible to set times according to the situation, such as schools / safe areas (30 seconds), school routes / public roads (3 minutes), dangerous areas (10 minutes), nighttime / holidays (7 minutes), etc. Furthermore, a custom setting function allows users to add and register their own unique combinations of locations and times. The setting priority is set with user manual settings having the highest priority, and a hierarchical control system is adopted in which location-specific automatic settings are applied only when no manual settings are made.

[0097] The widespread adoption of this system is expected to have social benefits such as reducing public anxiety regarding child safety, alleviating the psychological burden on parents, and improving safety awareness throughout the community. Furthermore, it may contribute to preventing serious accidents and crimes through rapid response in emergencies.

[0098] This invention aims to clarify the technical differences between the present invention and the prior art. The conventional system described in Patent Document 1 simply transmits location information when the buzzer sounds and does not have a function to determine the degree of urgency based on how the buzzer is stopped. The system in Patent Document 2 is designed on the premise of active input operation and does not anticipate a situation in which the user is unable to operate the system in a true emergency. In contrast, the present invention provides a groundbreaking discrimination system based on the reverse idea that a true emergency is a situation in which the user is unable to intentionally perform a stop operation. This technological concept represents a major paradigm shift from reliance on conventional active operation to passive situational judgment and possesses remarkable inventiveness.

[0099] [General tasks] One of the purposes of this disclosure is to enable appropriate notification control to parents depending on how the buzzer stops. One of the purposes of this disclosure is to provide a highly convenient monitoring technology while balancing user safety with the impact of alarm devices on the surrounding environment.
