Description

School accident detection and prevention system using radar for biosignal analysis and method of operation thereof

[0001] The present disclosure relates to a system for detecting and preventing accidents within a school and a method of operating the same. More specifically, the present disclosure relates to a system for detecting and preventing accidents within a school using a radar for biosignal analysis and a method of operating the same.

[0002] Recently, as social awareness regarding various incidents occurring within schools, such as school violence, emergencies, and theft, has increased, there is a growing need for systems capable of detecting and responding to students' situations in real time.

[0003] To address this, the conventional method of installing CCTVs is sometimes used; however, considering that incidents within schools, such as school violence, primarily occur in hidden areas, there are inevitably blind spots where such incidents cannot be detected. In particular, due to privacy concerns, there are restrictions on installing CCTVs in specific locations where school violence frequently occurs, such as restrooms, which creates a problem where existing methods are unable to adequately respond to incidents within schools.

[0004] Furthermore, regarding emergencies caused by students' health issues or theft incidents that frequently occur within schools, in addition to school violence, existing surveillance systems have a problem in that they operate only in limited situations or provide only static monitoring, making them unable to adequately respond to incidents within the school.

[0005] Ultimately, there was a demand for a school accident recognition and prevention system capable of responding appropriately in real-time to various accident situations that may occur within the school; however, conventional technology was unable to provide this, and the present disclosure aims to solve this problem.

[0006] The present disclosure is intended to provide a school accident detection and prevention system and a method of operation thereof that can respond appropriately in real time to various accident situations that may occur within a school.

[0007] Another objective of the present disclosure is to provide a school accident detection and prevention system using a radar for biosignal analysis and a method of operation thereof.

[0008] Another objective of the present disclosure is to provide an accident detection and prevention system within a school using a mobile camera capable of moving to the scene of an incident, and a method of operation thereof.

[0009] The purposes of the present disclosure are not limited to those mentioned above, and other purposes and advantages of the present disclosure not mentioned may be understood from the following description and will be more clearly understood by the embodiments of the present disclosure.

[0035] To clarify the technical concept of the present disclosure, embodiments of the present disclosure will be described in detail with reference to the attached drawings. In describing the present disclosure, detailed descriptions of related known functions or components will be omitted if it is determined that such detailed descriptions would unnecessarily obscure the essence of the present disclosure. Components having substantially the same functional configuration among the drawings have been assigned the same reference numerals and symbols as much as possible, even if they are shown in different drawings. For convenience of explanation, devices and methods will be described together where necessary. Each operation of the present disclosure does not necessarily have to be performed in the order described and may be performed in parallel, selectively, or individually.

[0036] The terms used in the embodiments of this disclosure have been selected to be as widely used and general as possible, taking into account the functions of this disclosure; however, these terms may vary depending on the intent of those skilled in the art, case law, the emergence of new technologies, etc. Additionally, in specific cases, terms have been selected at the applicant's discretion, and in such cases, their meanings will be described in detail in the description of the relevant embodiments. Therefore, terms used in this specification should be defined not merely by their names, but based on their meanings and the overall content of this disclosure.

[0037] Throughout this disclosure, singular expressions may include plural expressions unless the context clearly indicates otherwise. Terms such as "comprising" or "having" are intended to specify the existence of features, numbers, steps, actions, components, parts, or combinations thereof, and should be understood as not precluding the existence or addition of one or more other features, numbers, steps, actions, components, parts, or combinations thereof. That is, throughout this disclosure, when a part is described as "comprising" a certain component, it means that, unless specifically stated otherwise, it does not exclude other components but may include additional components.

[0038] Expressions such as "at least one" modify the entire list of components and do not modify the components of the list individually. For example, "at least one of A, B, and C" and "at least one of A, B, or C" refer to only A, only B, only C, both A and B, both B and C, both A and C, all of A, B, and C, or any combination thereof.

[0039] Additionally, terms such as "...part," "...module," etc., as described in this disclosure refer to a unit that processes at least one function or operation, and may be implemented in hardware or software, or a combination of hardware and software.

[0040] Throughout the entire disclosure, when a part is described as being "connected" to another part, this includes not only cases where they are "directly connected," but also cases where they are "electrically connected" with other elements interposed between them. Furthermore, when a part is described as "including" a certain component, this means that, unless specifically stated otherwise, it does not exclude other components but may include additional components.

[0041] Throughout this disclosure, the expression “configured to” may be replaced, depending on the context, with, for example, “suitable for,” “having the capacity to,” “designed to,” “adapted to,” “made to,” or “capable of.” The term “configured to” may not necessarily mean only “specifically designed to” in hardware. Instead, in some situations, the expression “system configured to” may mean that the system is “capable of” in conjunction with other devices or components. For example, the phrase “processor configured to perform A, B, and C” may mean a dedicated processor for performing the said operations (e.g., an embedded processor) or a generic-purpose processor (e.g., a CPU or an application processor) capable of performing said operations by executing one or more software programs stored in memory.

[0042] Throughout this disclosure, terms including ordinal numbers, such as first, second, etc., may be used to describe various components, but the components are not limited by the terms. The terms are used solely for the purpose of distinguishing one component from another. For example, without departing from the scope of this disclosure, the first component may be named the second component, and similarly, the second component may be named the first component. The term “and / or” includes a combination of multiple related items or any one of the multiple related items.

[0043] Throughout the entire disclosure, a terminal or terminal may include a UE (User Equipment), MS (Mobile Station), cellular phone, smartphone, computer, smart watch, Bluetooth earphone, or a multimedia system capable of performing communication functions. Of course, it is not limited to the above examples.

[0044] Throughout the entire disclosure, the first location information is location information regarding a detected biosignal, and may be the place where the biosignal is detected or its coordinates. Alternatively, it may be the installation location of the first radar unit that detected the biosignal. For example, if a first radar unit installed in a hallway detects a biosignal in Classroom A, the first location information regarding the biosignal may be the coordinates of Classroom A or the hallway. This is not limited to the examples described above and can be configured in various ways. However, for the sake of convenience of explanation, the present disclosure describes the case where the first location information is the coordinates of the biosignal as an example.

[0045] Throughout the entire disclosure, a management terminal is a terminal used in a control room or by an administrator, and may include an output unit that outputs a notification when connected to a school safety server and receives a notification.

[0046] FIG. 1 is a drawing illustrating an accident detection and prevention system within a school according to one embodiment of the present disclosure.

[0047] Referring to FIG. 1, an accident detection and prevention system (10) in a school according to one embodiment of the present disclosure may include a first radar unit (100), a camera unit (200), and a school safety server (300). However, not all of the accident detection and prevention system in a school shown in FIG. 1 are essential components, and it may be implemented by more components than those shown in FIG. 1, or by fewer components.

[0048] In one embodiment, each component may be connected via a private communication network or via a private communication network and at least one external communication network. Here, the external communication network refers to a connection structure capable of exchanging information between each node, such as a plurality of terminals and servers, and may be a communications network. The communications network may include at least one of a computer network, the Internet, a wireless network, or a wired telephone network. For example, the wireless network may include a 3G, 4G, 5G, or 6G mobile telephone network. In one embodiment, the first radar unit (100), the imaging unit (200), and the school safety server (300) may be connected via a private communication network.

[0049] An accident detection and prevention system (10) within a school according to one embodiment of the present disclosure may further include a gateway (400). Referring to FIG. 1, the first radar unit (100) and the imaging unit (200) are connected via a private communication network, and the school safety server uses an external communication network, and a gateway (400) may be used to connect the two different communication networks. Additionally, the role of the gateway (400) may be performed by a proxy server or a school safety server (300). That is, the gateway (400) is an example of a system based on a private communication network and may be omitted or configured in various forms.

[0050] One embodiment of the present disclosure can enhance the reliability and stability of data transmission, as well as security, by using a private communication network.

[0051] For convenience of explanation, the gateway (400) is omitted below, and the school safety server (300) communicates directly.

[0052] In one embodiment, the first radar unit (100) is installed at each facility of the school to detect biosignals. This will be described in more detail later with reference to FIG. 2.

[0053] In one embodiment, the shooting unit (200) is installed to be movable within the school so that it can move to the scene and take pictures when an abnormal situation occurs. For example, the shooting unit (200) can be installed to be movable within the school using a rail (290). This will be described in more detail later with reference to FIG. 3.

[0054] In one embodiment, when an abnormal situation occurs, the school safety server (300) can send a notification to the control room (310) or a pre-registered management terminal (350). This will be described in more detail later with reference to FIG. 4.

[0055] FIG. 2 is a block diagram illustrating the configuration of a first radar unit according to one embodiment of the present disclosure.

[0056] Referring to FIG. 2, a first radar unit (100) according to one embodiment of the present disclosure may include a first radar module (110), a first communication module (120), and a control module (130).

[0057] In one embodiment, the first radar module (110) can transmit a radar signal to a surrounding area and receive a reflected signal. For example, the first radar module (110) may use a UWB (Ultra-wide band) radar, a CW (Continuous wave) radar, an FMCW (Frequency modulated continuous wave) radar, etc. However, this is exemplary and the type of the first radar module (110) used to detect a biosignal is not limited thereto.

[0058] In one embodiment, the first radar module (110) can measure the movement of the human body or detect biosignals using radar signals. For example, the first radar module (110) can measure the movement or posture of the human body using radar signals. Additionally, the first radar module (110) can detect the movement of the thoracic cavity during breathing or detect the heartbeat using radar signals. That is, the first radar module (110) can measure biosignals such as the human body's respiration or heart rate.

[0059] In one embodiment, the first communication module (120) may be connected to the imaging unit (200) and / or the school management server (300) through the self-communication network and / or external communication network described above with reference to FIG. 1, respectively. For example, the first communication module (120) may transmit information detected by the first radar module (110) to the imaging unit (200) and / or the school management server (300), and receive control commands from the imaging unit (200) and / or the school management server (300).

[0060] In one embodiment, the control module (130) can control the operation of the various components of the first radar unit (100). For example, the control module (130) may include at least one processor, and the at least one processor may be any form for data processing, data analysis, and / or deep learning, such as a Central Processing Unit (CPU), a General Purpose Graphics Processing Unit (GPGPU), or a Tensor Processing Unit (TPU), but is not limited thereto. In addition, even without separate explanation, the operation of the first radar unit (100) described below may be understood as being performed by the control of the control module (130).

[0061] In one embodiment, the control module (130) can analyze the signal received by the first radar module (110) to extract and detect the movement of the human body or the biosignals of the human body. For example, the control module (130) can detect whether the human body has fallen or biosignals such as the human body's respiration and heart rate.

[0062] In one embodiment, the control module (130) can transmit the detected biosignal and first location information regarding the biosignal to the school safety server (300), which will be described later with reference to FIG. 4, via the communication module (120). For example, if the first radar unit is installed in a restroom, the biosignal is not detected if there is no person, such as a student or faculty member, so a signal indicating that the biosignal is not detected may be transmitted, or no data may be transmitted. When a person enters and the biosignal is detected, the biosignal and the first location information regarding the biosignal may be transmitted to the school safety server until the person leaves. Here, the first location information may be coordinate information according to a predetermined coordinate system (e.g., a coordinate system with a certain location within the school as the origin). As another example, the first location information may be zone information according to predetermined zones (e.g., dividing the school into zones A through Z).

[0063] In one embodiment, the control module (130) can determine whether an abnormal situation has occurred by analyzing the detected biosignal. At this time, if an abnormal situation has occurred, the control module (130) can determine the type of event of the abnormal situation. For example, the types of events may include 'health abnormality', 'school violence', 'occupancy detection', etc. Subsequently, the control module (130) can generate an event occurrence signal containing the detected and analyzed biosignal, first location information regarding the biosignal, and information regarding the type of event, and transmit it to the camera unit (200) and / or the school safety server (300) via the communication module (120).

[0064] For example, when a person enters a restroom equipped with the first radar unit, the first radar unit can detect the person's vital signs and analyze them in real time. Furthermore, if the person who entered the restroom collapses due to difficulty breathing, the first radar unit can detect a sudden change in the respiratory rate, determine that 'difficulty breathing' has occurred, and then transmit an event occurrence signal containing the relevant information (difficulty breathing), vital signs, and restroom coordinates to the camera unit and / or the school safety server described later.

[0065] In another embodiment, the control module (130) transmits the detected biosignal and first location information regarding the biosignal to the school safety server (300), and the school safety server (300) can analyze the transmitted biosignal to determine whether an abnormal situation has occurred. In one embodiment, if an abnormal situation occurs, the control module (130) can determine the type of event of the abnormal situation. For example, the types of events may include 'health abnormality', 'school violence', 'occupancy detection', etc. Subsequently, the control module (130) can generate an event occurrence signal containing the detected and analyzed biosignal, first location information regarding the biosignal, and information regarding the type of event, and transmit it to the camera unit (200) and / or the school safety server (300) via the communication module (120).

[0066] FIG. 3 is a block diagram illustrating the configuration of a photographing unit according to one embodiment of the present disclosure, and FIG. 4 is a perspective view of a photographing unit according to one embodiment of the present disclosure.

[0067] Referring to FIG. 3, a shooting unit (200) according to one embodiment of the present disclosure may include a moving module (210), a camera (220), a second communication module (230), and a shooting control module (240).

[0068] In the following description, any description of the second communication module (230) that overlaps with the communication module (120) is omitted. Any description of the shooting control module (240) that overlaps with the control module (130) is omitted.

[0069] In one embodiment, the movement module (210) is configured to allow the imaging unit (200) to move, and may be configured to move within the school, particularly to an area where the first radar unit (100) cannot detect. For example, as shown in FIG. 4, the movement module (210) may be configured so that the imaging unit (200) can move along a rail (290) installed on the ceiling. At this time, it goes without saying that the movement module (210) can be configured in various ways to obtain similar functions and effects.

[0070] In one embodiment, the camera (220) can capture an abnormal situation and generate image data.

[0071] In one embodiment, the second communication module (230) may be connected to the first radar unit (100) and / or the school management server (300), etc., through the aforementioned private communication network and / or external communication network with reference to FIG. 1.

[0072] In one embodiment, the second control module (240) can perform control for the operation of the various components of the shooting unit (200), and even without separate explanation, the operation of the shooting unit (200) described below can be understood as being performed by the control of the second control module (240).

[0073] In one embodiment, when the second control module (240) receives an event occurrence signal, it can cause the imaging unit (200) to move to a first location included in the event occurrence signal. For example, if a student collapses in a restroom due to difficulty breathing, when the imaging unit receives the event occurrence signal, it can move to the restroom coordinates where the student was detected.

[0074] In one embodiment, the recording unit (200) may further include a warning module (250) that outputs a warning message generated based on the type of incident while moving to a first location in order to urgently notify of the escalation of an accident or the situation. For example, assuming a case where a student has collapsed, the recording unit may move to the location and, while doing so, inform students who are unaware of the situation to guide them to the location where the patient is, or request help from nearby people and guide them on the correct response method so that the golden time is not missed. Alternatively, if students remain on campus after a certain period of time has elapsed, it may notify them that the exit time has passed.

[0075] In one embodiment, the imaging unit (200) may further include a second radar module (260) to resolve situations where proper imaging is difficult, such as when an abnormal situation moves over time. For example, the second radar module (260) can track the current location of the abnormal situation by detecting a biosignal while the imaging unit (200) is moving to a first location or at the first location. Additionally, while moving to the first location, the second radar module (260) can track the biosignal using a radar signal to identify the current location of the abnormal situation as a second location and cause the imaging unit (200) to move to the second location. Furthermore, the imaging unit (200) can be controlled to perform various operations to further improve the quality of image data, such as adjusting the shooting angle, based on the biosignal detected by the second radar module (260).

[0076] In one embodiment, assuming a case where school violence occurs in a hallway and the victim is dragged to a restroom, the recording unit (200) will move to the hallway, which is the first location initially guided, but at the time of arrival, no situation may be unfolding at that location. At this time, through the second radar module (260), the recording unit (200) can detect biosignals occurring in the surrounding area, move to the restroom, which is the location where the incident is currently taking place, and record the situation.

[0077] FIG. 5 is a block diagram illustrating the configuration of an in-school safety server according to one embodiment of the present disclosure.

[0078] Referring to FIG. 5, a school safety server (300) according to one embodiment of the present disclosure may include a storage module (310), a server communication module (320), and a server control module (330).

[0079] In the following description, any description of the server communication module (320) that overlaps with the communication module (120) is omitted. Any description of the server control module (330) that overlaps with the control module (130) is omitted.

[0080] In one embodiment, the storage module (310) may include volatile memory and non-volatile memory. For example, it may be configured to include flash memory, a hard disk, an SSD, a card-type memory (e.g., SD or XD memory, etc.), ROM, RAM, EEROM, EPROM, EEPROM, etc. Alternatively, the storage module (310) may include a file system, a database, or an embedded database. The description of the storage module (310) described above is merely an example and the present disclosure is not limited thereto.

[0081] In one embodiment, the storage module (310) can store image data when the school safety server (300) receives the image data recording the aforementioned abnormal situation. By doing so, the corresponding image data can be utilized in the future when an accurate record of that time is required (e.g., the occurrence of a legal dispute).

[0082] In one embodiment, the storage module (310) can store various data necessary for the school safety server (300) to perform the operation described below. For example, the storage module (310) can store data such as registered management terminals (301) that have the authority to receive notifications in the event of an abnormal situation.

[0083] In one embodiment, the server communication module (320) may be connected to the first radar unit (100), the shooting unit (200), or a pre-registered management terminal (301), etc., through the self-communication network and / or external communication network described above with reference to FIG. 1.

[0084] In one embodiment, the server control module (330) can perform control for the operation of the various components of the school safety server (300), and even without separate explanation, the operation of the school safety server (300) described below can be understood as being performed by the control of the server control module (330).

[0085] In one embodiment, the server control module (330) can transmit a notification to the management terminal (301) through the server communication module (320). At this time, the notification may include a biosignal, a first location (or information), an event type, and image data.

[0086] In one embodiment, the server control module (330) can analyze the biosignal received from the first radar unit (100) and determine whether an abnormal situation has occurred based on the analysis. At this time, if it is determined that an abnormal situation has occurred, the type of abnormal situation can be determined. By having the school safety server (300) perform complex biosignal analysis, the computational burden on the radar unit (100) can be reduced and costs can be saved.

[0087] Subsequently, the server control module (330) can generate an event occurrence signal including first location information and transmit it to the shooting unit (200). Furthermore, in one embodiment, the event occurrence signal transmitted from the server control module (330) to the shooting unit (200) may further include an event type. Through this, the shooting unit (200), which further includes a warning module (250), can output a warning message based on the event type.
