Description

Technical Field

[0001] The technical idea of the present disclosure relates to a method for transmitting an emergency rescue signal, and more particularly, to a method for transmitting an emergency rescue signal by an auxiliary device that communicates wirelessly with a user terminal.

Background Art

[0002] Recently, smartphones have become widely popular, and smartphones equipped with a function to generate an emergency rescue signal have been developed, and the demand for services related to the emergency rescue system has been steadily increasing. The emergency rescue signal is generated by physically pressing a function button provided on the smartphone directly, and the generated emergency rescue signal may be provided at a public security management center through a communication company server.

[0003] However, since the conventional emergency rescue signal has only a very limited function, there is a lack of linkage with other applications. In addition, it is very difficult for an individual in an emergency situation to secure his / her own smartphone and operate it calmly.

[0004] The function button provided on the smartphone is formed in a very small size considering psychological factors, and since many operations are involved to prevent malfunction, there is also a side that a request signal cannot be generated even in an emergency situation.

[0005] That is, in a situation where a separate device for generating an emergency rescue signal is required, or when the size of the button for generating the signal is large and it is necessary to prevent malfunction caused by accidental pressing of the button, there is a situation where a separate device manufactured in a size and weight with excellent portability is lacking. In addition, there is also a situation where a signal transmission method that stably generates an emergency rescue signal by such a separate device and has security for personal information is lacking.

[0025] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.

[0026] FIG. 1 is a block diagram showing components of an emergency assistance request system 1 according to an embodiment of the present disclosure.

[0027] Referring to FIG. 1, the emergency rescue request system 1 may include an auxiliary device 10, a user terminal 20, and a management server 30. The user terminal 20 can be connected to and communicate with the auxiliary device 10 and the management server 30, and can send an emergency rescue signal to the management server 30 by receiving a trigger signal from the auxiliary device 10.

[0028] According to one embodiment, the auxiliary device 10 and the user terminal 20 may be connected through short-range wireless communication, and one auxiliary device 10 can perform wireless communication with one user terminal 20. On the contrary, one user terminal 20 may be communicatively connected to a plurality of auxiliary devices 10, and a list of the auxiliary devices 10 communicatively connected through an application installed on the user terminal 20 can be checked.

[0029] The management server 30 can receive an emergency rescue signal from the user terminal 20. The generated emergency rescue signal can include encrypted user status data, and the user status data can include image data and / or audio data obtained by the user terminal 20. The image data and / or audio data can be obtained by executing the camera application and / or the recording application of the user terminal 20.

[0030] In order for the user terminal 20 to obtain image data and audio data, the control authority for the applications that can obtain the image data and audio data in the emergency rescue application that can send and receive signals in conjunction with the auxiliary device 10 must be granted. That is, in order for the user terminal 20 to generate an emergency rescue signal, the control authority for the camera application and the recording application must be granted to the emergency rescue application in advance. In addition, the user terminal 20 may also grant the control authority for the application that can obtain GPS to the emergency rescue application in order to obtain the terminal position information in the user status data.

[0031] According to an embodiment, at the stage of initial setting for the emergency rescue application, the user terminal 20 can request the user to select whether to grant control authority to any application, and the control authority for the selected application can be granted to the emergency rescue application.

[0032] Exemplarily, when the user terminal 20 grants only the control authority for the camera application to the emergency rescue application through the user's selection input, only the image data captured by the camera application can be generated as the user status data. On the contrary, when the user terminal 20 grants the control authority for the camera application and the recording application to the emergency rescue application through the user's selection input, the image data captured by the camera application and the audio data recorded by the recording application can be generated as the user status data. The user terminal 20 can generate an emergency rescue signal based on the generated user status data and provide the emergency rescue signal to the management server 30. The data obtained by the user terminal 20 will be described in detail later through FIG. 6.

[0033] According to an embodiment, the management server 30 can identify the protector terminal 40 that has requested pairing with the user terminal 20, and the management server 30 or the user terminal 20 can approve the pairing of the protector terminal 40 with the user terminal 20. When the management server 30 receives an emergency rescue signal from the user terminal 20, it can send the emergency rescue signal to the paired protector terminal 40. At this time, the management server 30 can decrypt the user status data included in the emergency rescue signal and provide it to the protector terminal 40, but the embodiments of the present disclosure are not limited thereto, and only the alarm information indicating that the emergency rescue signal has been sent to the management server 30 may be provided.

[0034] FIG. 2 is a block diagram showing the components of the auxiliary device 10 according to an embodiment.

[0035] The auxiliary device 10 can be a terminal auxiliary device 10 that can be attached to and detached from the user terminal 20, or it may be a stationary auxiliary device 10 that can be attached to and detached from an object instead of the user terminal 20. The auxiliary device 10 can be a device with portability so that the user can carry it when the auxiliary device 10 is detached from the user terminal 20 or the object.

[0036] Referring to FIG. 2, the auxiliary device 10 can include a switch 110, a processor 120, and a communication module 130, and can be mounted on a single substrate. The switch 110 can be connected to an externally exposed button, and for example, when the user presses the button, a path through which power is supplied from a battery or a power supply device to the processor 120 and / or the communication module 130 can be connected. The processor 120 and the communication module 130 that receive power supply can generate a trigger signal under certain conditions and transmit it to the user terminal 20.

[0037] The specific configuration in which the switch 110 of the auxiliary device 10 is connected through an externally arranged button to generate and transmit a trigger signal will be described later with reference to FIGS. 7 to 12.

[0038] The communication method of the communication module 130 can be at least one of short-range wireless communication methods such as Bluetooth, ZigBee, Beacon, RFID (Radio Frequency Identification), UWB (Ultra Wideband), or infrared communication. That is, the auxiliary device 10 can be connected to the user terminal 20 by a short-range wireless communication method and transmit a trigger signal.

[0039] According to an embodiment, when the operations requested by the user terminal 20 are performed by the auxiliary device 10 when connected by a short-range wireless communication method, the user terminal 20 and the auxiliary device 10 can be paired, and the emergency rescue application installed in the user terminal 20 can be given access rights to the auxiliary device 10. The access rights can be the rights to receive the provision of a trigger signal, and when the access rights to the target auxiliary device 10 are given to the user terminal 20, the user terminal 20 can control the camera application and / or the recording application in response.

[0040] At this time, the user terminal 20 can request a specific operation for user confirmation of the target auxiliary device 10 in the emergency rescue application. For example, the user terminal 20 can request the operation of pressing the button of the target auxiliary device 10 three times. When the user presses the target auxiliary device 10 three times, the user terminal 20 can be given access rights to the target auxiliary device 10.

[0041] That is, the pairing between the user terminal 20 and the auxiliary device 10 is made unilaterally by the user terminal 20 for the request and confirmation of pairing, and it may occur that the auxiliary device 10 is paired with the wrong user terminal 20 unintentionally. Along with this, even if the user terminal 20 and the target auxiliary device 10 are paired at the communication module 130 side, when the user terminal 20 does not have access rights to the target auxiliary device 10 at the application layer side, the corresponding user terminal 20 can be recognized as a wrongly connected terminal, so as to prevent the fraud of the user state data by the auxiliary device 10.

[0042] FIG. 3 is a block diagram showing the components of the user terminal 20 according to an embodiment.

[0043] Referring to FIG. 3, the user terminal 20 can include a processor 210, a RAM (Random Access Memory) 220, a storage 230, and a communication module 240.

[0044] The processor 210 can control the overall operation of the user terminal 20. The processor 210 can include a CPU (Central Processing Unit) that includes one processor core (Single Core) or multiple processor cores (Multi-Core). The user terminal 20 can include one or more processors 210.

[0045] The processor 210 can process or execute programs, data, or instructions stored in the storage 230. For example, the processor 210 can acquire image data and / or audio data by executing a program stored in the storage 230, and can process the acquired data to generate user state data. Further, the processor 210 can use the generated user state data to generate an emergency rescue signal according to a communication protocol and provide it to the management server 30.

[0046] The RAM 220 can temporarily store programs, data, or instructions. For example, the programs and / or data stored in the storage 230 can be temporarily stored in the RAM 220 under the control of the processor 210 or the booting code. For example, the RAM 220 includes DRAM (Dynamic RAM), SRAM (Static RAM), SDRAM (Synchronous DRAM), etc.

[0047] Storage 230 is a storage location for storing data, and can store an OS (Operating System), various programs, and various data. Storage 230 includes ROM (Read Only Memory), flash memory, PRAM (Phase-change RAM), MRAM (Magnetic RAM), RRAM (Resistive RAM), FRAM (Ferroelectric RAM), etc. In an embodiment, storage 230 can be implemented by an HDD (Hard Disk Drive), an SSD (Solid State Drive), etc.

[0048] The communication module 240 can transmit and / or receive data of the user terminal 20. For example, the communication module 240 can transmit and receive data by various communication methods. For example, the communication module 240 can perform communication by, for example, 3G, LTE, Wi-Fi, Bluetooth, BLE (Bluetooth Low Energy), Zigbee, NFC (Near Field Communication), a communication method through ultrasonic waves, etc., and can include all of wired communication, wireless communication, short-distance communication, and long-distance communication.

[0049] According to an embodiment, the user terminal 20 can transmit and receive data / information with the auxiliary device 10 using short-distance wireless communication, and can transmit and receive data / information with the management server 30 using long-distance wireless communication.

[0050] Therefore, the user terminal 20 of the present disclosure can perform operations with the above configuration, temporarily store data or instructions, and perform data transmission and / or reception with other user terminals 20.

[0051] The user terminal 20 can be applied to a smart TV, a smartphone, a mobile device, a video display device, a measurement device, an IoT (Internet of Things) device, etc., and can also be applied to and implemented as one of various types of electronic devices.

[0052] The user terminal 20 can include various types of IP blocks. For example, although not shown in FIG. 3, the user terminal 20 can further include other general components such as input / output devices, a neural network processor, an MFC (Multi-Format Codec), a video module (e.g., a camera interface, a JPEG (Joint Photographic Experts Group) processor, a video processor, or a mixer, etc.), a 3D graphics core, an audio system, a display driver, a GPU (Graphic Processing Unit), a DSP (Digital Signal Processor), and the like.

[0053] In an embodiment, at least some of the components of the user terminal 20 can be implemented with one semiconductor chip. For example, the user terminal 20 can be implemented as a system-on-chip (SoC). However, it is not limited thereto, and the user terminal 20 can be implemented with a plurality of semiconductor chips. In one embodiment, the user terminal 20 can be implemented with an application processor mounted on a mobile device.

[0054] FIG. 4 is a flowchart illustrating a method for generating an emergency rescue signal according to an embodiment.

[0055] Referring to FIG. 4, when a trigger signal is generated from the auxiliary device 10 and provided to the user terminal 20, an emergency rescue signal can be generated and provided to the management server 30. When the emergency rescue application is running as a background application, the trigger signal can be a user terminal 20 control signal that causes the camera application / recording application that has undergone a normal access authentication process to operate in the emergency rescue application.

[0056] In step (S110), when a push input is applied to the switch of the auxiliary device 10, the auxiliary device 10 can provide a trigger signal to the user terminal 20. Exemplarily, the trigger signal can be a communication signal that follows the protocol of Bluetooth communication, and can be a signal transmitted to the user terminal 20 paired through Bluetooth communication.

[0057] In step (S120), when the user terminal 20 receives a trigger signal from the auxiliary device 10, at least one of image data and audio data related to the user state can be generated based on the trigger signal. When the user terminal 20 is paired with a plurality of auxiliary devices 10, when receiving a trigger signal from at least one of the plurality of auxiliary devices 10, at least one of image data and audio data can be generated.

[0058] The image data can be image data that is captured automatically under the control of the emergency rescue application without user operation when the camera application is executed. As soon as the user terminal 20 receives the trigger signal, all the cameras provided in the user terminal 20 can be activated, and all the images around the user captured by the cameras can be taken.

[0059] The audio data can be audio data that is recorded automatically under the control of the emergency rescue application without user operation when the recording application is executed. At this time, the user terminal 20 can generate first audio data that records the surrounding audio during the first time interval, and can determine the length of the time interval of the audio data generated successively according to whether the transmission of the first audio data to the management server 30 is successful.

[0060] According to an embodiment, the user terminal 20 generates first audio data by recording ambient audio during a first time interval based on a trigger signal, and can generate second audio data by recording ambient audio during a second time interval longer than the first time interval after generating the first audio data. Exemplarily, the first time interval can be 10 seconds and the second time interval can be 30 seconds. The first time interval can be the minimum time interval for the user terminal 20 or the management server 30 to determine the surrounding situation, and the second time interval can be the minimum time interval required for evidence collection. When generating an emergency rescue signal, the determination of the surrounding situation may be given higher priority compared to evidence collection. Accordingly, audio data of a first time interval shorter than the second time interval can be collected and transmitted to the management server 30.

[0061] The user terminal 20 of the present disclosure can transmit the first audio data to the management server 30 before generating the second audio data. If the transmission of the first audio data is successful, the second audio data can be generated. On the contrary, if the user terminal 20 fails to transmit the first audio data, it can generate third audio data by recording ambient audio during a third time interval shorter than the first time interval. When the transmission of the first audio data fails, it may be the case where the size of the data of the emergency rescue signal generated based on the first audio data is larger than the quality of the data communication, and a communication failure between the management server 30 and the user terminal 20 may become a problem. Therefore, the user terminal 20 can generate the third audio data with a size smaller than that of the first audio data, and can transmit the emergency rescue signal to the management server 30 again based on the generated third audio data.

[0062] At this time, the third time interval of the generated third audio data can be determined based on whether the transmission of the continuous emergency rescue signal is successful, or can be determined based on the type / signal strength of the communication with the management server 30. Exemplarily, the user terminal 20 may determine the length of the third time interval according to whether it is communicating with the management server 30 via WIFI or LTE.

[0063] In step (S130), the user terminal 20 can encrypt the data collected through the camera application or the recording application into user status data. Exemplarily, the user terminal 20 can encrypt the user status data through a personal encryption key, and the public encryption key paired with the personal encryption key is stored in the management server 30, and the management server 30 can decrypt the encrypted user status data. In addition, the user terminal 20 can use various types of encryption methods to encrypt the image data and audio data into user status data, and there is a corresponding decryption key in the management server 30 to decrypt the user status data into image data and audio data.

[0064] In step (S140), the user terminal 20 can provide the encrypted user status data to the management server 30 as an emergency rescue signal. The user terminal 20 can generate data packets according to the protocol that matches the corresponding communication according to the communication type connected to the management server 30. At this time, the user status data can be included in the data packets and provided to the management server 30.

[0065] According to an embodiment, when the management server 30 receives an emergency rescue signal more than a preset number of times, it can search for the public security management center around the location of the user terminal 20, and provide the user's information and the location of the user terminal 20 to the searched public security management center. Accordingly, the management server 30 can notify the public security management center that the user is in an emergency rescue situation automatically without taking separate measures.

[0066] FIG. 5 is a flowchart illustrating a method of providing an emergency rescue signal to the management server 30 by generating / transmitting a series of signals from the auxiliary device 10 to the management server 30 according to an embodiment.

[0067] Referring to FIG. 5, while sequentially transmitting a series of signals from the auxiliary device 10 to the management server 30, the emergency situation of the user can be notified to the management server 30. At stage (S1100), the auxiliary device 10 can generate a trigger signal, and at stage (S1200), the auxiliary device 10 can provide the trigger signal generated at the user terminal 20 to the user terminal 20. At this time, the auxiliary device 10 can provide the trigger signal to the user terminal 20 through short-range wireless communication.

[0068] At stage (S1300), the user terminal 20 can generate at least one of image data and audio data, and at stage (S1400), the user terminal 20 can encrypt at least one of the image data and audio data into user status data. At this time, when the user terminal 20 has secured all of the image data and audio data, it can combine them and encrypt them into user status data.

[0069] At stage (S1500), the user terminal 20 can provide the encrypted user status data to the management server 30 as an emergency rescue signal. The user terminal 20 can provide the emergency rescue signal to the management server 30 through long-range wireless communication.

[0070] FIG. 6 is a drawing illustrating a method of generating user status data from data generated by the user terminal 20 according to an embodiment.

[0071] Referring to FIG. 6, data for checking the user status can be collected through a plurality of functional devices provided in the user terminal 20, and the collected data can be merged and generated as user status data. At this time, the user status data can be data obtained by merging and encrypting multiple types of data. The multiple types of data can include image data, audio data, and terminal position data. When the user terminal 20 is equipped with a first camera and a second camera, the first image data and the second image data simultaneously captured from each camera can be used to generate the user status data.

[0072] According to an embodiment, the combination of data collected may vary depending on the control authority granted to the emergency rescue application of the user terminal 20 and the types of functional devices provided in the user terminal 20. When the emergency rescue application is granted the control authority of the camera application and the recording application, the user terminal 20 can secure image data and audio data. In addition, when the user terminal 20 obtains the control authority for an application that can obtain GPS in order to acquire terminal location information as user status data, it can secure terminal location data.

[0073] In addition, the user terminal 20 can obtain connection strength data with the auxiliary device 10 that has sent the trigger signal. When the user terminal 20 communicates with the auxiliary device 10 through Bluetooth communication, an RSSI (Signal Strength Indicator) value can be obtained through the trigger signal, and connection strength data can be generated based on the RSSI value.

[0074] When the management server 30 obtains the connection strength data by decrypting the user status data, the distance between the auxiliary device 10 and the user terminal 20 can be inferred from the connection strength data, and the user status based on the distance inferred by the guardian terminal 40 or the user terminal 20 can be notified.

[0075] Exemplarily, when the distance inferred from the connection strength data by the management server 30 is far, the management server 30 can display through the application of the user terminal 20 or the guardian terminal 40 that the user having the auxiliary device 10 is located far from the user terminal 20. That is, it may mean that in a situation where an emergency rescue signal is being transmitted while being far away from the user terminal 20, there is a high possibility that the guardian who has confirmed this cannot connect with the user even if contacting the user.

[0076] On the contrary, when the distance inferred from the connection strength data is short, the management server 30 can display, through the applications of the user terminal 20 or the guardian terminal 40, that the user having the auxiliary device 10 is located close to the user terminal 20. That is, since an emergency rescue signal is being transmitted in a situation where the user is located close to the user terminal 20, it may also mean a state where there is a high possibility of connection when the guardian who has confirmed this contacts the user.

[0077] Accordingly, when the management server 30 determines that the user terminal 20 and the auxiliary device 10 are located far apart, it can assign a higher urgency level than when it determines that they are located close. The management server 30 can determine whether the user terminal 20 and the auxiliary device 10 are located far apart based on whether the RSSI value is greater than a reference value.

[0078] FIGS. 7A to 10 are drawings illustrating the components of the auxiliary device 10a according to the first embodiment.

[0079] The auxiliary device 10a according to the first embodiment may be an auxiliary device 10a configured to be detachable from the user terminal 20. The auxiliary device 10a may include an annular member 150, and the annular member 150 may be rotated by a hinge member 140, and the hinge member 140 may be fixed in a rotated state. Exemplarily, the hinge member 140 may be configured such that a circular pin is inserted into an elliptical hole instead of a circular hole, and a frictional force is ensured during press-fitting, and an additional frictional force may be applied during rotation. The hinge member 140 is not limited thereto, and all types of members that can fix the annular member 150 when it is rotated at an angle desired by the user, such as a spring pin, may be used.

[0080] According to one embodiment, the housing of the auxiliary device 10a may be configured to accommodate a magnetic body, and the magnetic body may be disposed in an outward direction along the outer peripheral surface of the auxiliary device 10a. The auxiliary device 10a may be attached to and detached from the user terminal 20 through the magnetic body, and may be configured to be rotated along the outer peripheral surface of the auxiliary device 10a while being attached to the user terminal 20.

[0081] The auxiliary device 10a that is attached to and detached from the user terminal 20 must be designed to have a low height in consideration of the user's portability, and components such as the battery 180, the switch 110, the button 160, and the magnetic body must be mounted. That is, it may be important to arrange the components as efficiently as possible in the limited space and stably couple them to the housing.

[0082] The auxiliary device 10a may have a button 160 that can press the switch 110 exposed outside the housing. The button 160 may be disposed on the upper portion of the substrate 170 on which the switch 110 is mounted, and the processor 120 and the communication module 130 may be mounted on the substrate 170 around the switch 110. Accordingly, it can be said that the support member 165 that supports the button 160 in the housing must be disposed limitedly while occupying as little space on the substrate 170 as possible.

[0083] Exemplarily, the support member 165 may not be directly connected to the substrate 170 but may be connected to the upper plate 11 of the auxiliary device 10a. The support member 165 of the button 160 may extend in the outer direction from the space where the button 160 is exposed to the outside, and the support member 165 may be connected to the upper plate 11 through screw fastening.

[0084] A battery 180 can be mounted below the substrate 170, and a battery fixing member 190 for accommodating the battery 180 and supplying power to the substrate 170 can be arranged. The battery fixing member 190 can be formed in a size corresponding to the size of the battery 180, and the substrate 170 can be placed and arranged on the battery fixing member 190. The battery fixing member 190 can be connected to the external housing through screw fastening or hook fastening. Exemplarily, a fastening groove capable of screw fastening is formed on the first side of the battery fixing member 190, and a hook that can be applied to the housing may be formed on the other second side. The substrate 170 and the battery fixing member 190 may have fastening grooves formed at corresponding positions, and the substrate 170 and the battery fixing member 190 can be connected to the upper plate plate 11 through the fastening grooves.

[0085] That is, a battery 180, a battery fixing member 190, a substrate 170, and a button 160 can be arranged between the upper plate plate 11 and the lower plate plate 12 of the auxiliary device 10a, and the battery fixing member 190, the substrate 170, the button 160, and the upper plate plate 11 can be sequentially stacked and assembled from the lower plate plate 12 constituting the housing.

[0086] According to an embodiment, the button 160 that can be pressed by a user can be composed of a plurality of parts, and a switch 110 having contacts formed corresponding to each of the plurality of parts can be mounted on the substrate 170. At this time, the auxiliary device 10a can generate a trigger signal in response when all of the plurality of switches 110 are pressed.

[0087] Exemplarily, when the button 160 is configured by dividing into two parts, two switches 110 corresponding to each part can be arranged on the substrate 170. The auxiliary device 10a can generate a trigger signal in response when all of the two switches 110 are pressed by each part.

[0088] The auxiliary device 10a of the present disclosure is a device carried by a user, and can be used in an environment where the button 160 is frequently accidentally pressed by other elements during carrying. Since the button 160 of the auxiliary device 10a is located at a position lower than the upper plate 11, there is a frequent tendency for it to malfunction because any one point of the button 160 is more likely to be pressed than the entire button 160 being accidentally pressed.

[0089] The button 160 of the auxiliary device 10a of the present disclosure is composed of a plurality of parts, and the auxiliary device 10a can generate a trigger signal only when all the switches 110 that come into contact with each part are pressurized. Therefore, it is possible to prevent a situation where only one point of the button 160 is pressed and a trigger signal is sent.

[0090] More specifically, when the button 160 is composed of the first part 160a and the second part 160b, a malfunction of the button 160 may occur when only one of the first part 160a and the second part 160b is pressed. Accordingly, the auxiliary device 10a of the present disclosure can generate a trigger signal only when the user presses all of the first part 160a and the second part 160b, thereby maximizing the prevention of malfunctions of the button 160.

[0091] Figs. 11 to 12 are drawings showing the components of the auxiliary device 10 according to the second embodiment.

[0092] The auxiliary device 10 according to the second embodiment can be configured to be portable by a user. A battery, a battery fixing member, a substrate, and buttons can be arranged between the upper plate and the lower plate of the auxiliary device 10, and the battery fixing member, the substrate, the buttons, and the upper plate can be sequentially stacked and assembled from the lower plate that constitutes the housing.

[0093] Also, a magnetic body can be arranged along the outer peripheral surface of the lower plate of the auxiliary device 10, and the auxiliary device 10 can be attached to a metal body by the magnetic body of the auxiliary device 10.
