Description

Emergency determination device

The present invention relates to an emergency situation determination device capable of determining whether an emergency has occurred to a person by detecting a human biosignal and a human hand motion.

As healthcare technology advances, various devices for improving the quality of life are being developed. In addition, electronic devices including sensors capable of measuring a human biosignal have been developed. As such, a user who uses the electronic device may measure information related to the body and determine his / her physical state using the electronic device. Such a device may use sensors to measure various biosignals such as heart rate, oxygen saturation, stress, and blood pressure of a user. The electronic device may measure various bio-signals of the user using the sensing information acquired through the sensor.

An emergency situation can occur in a person's body while a person is sleeping or resting on a bed. When a person lives alone indoors, there is a problem that even when an emergency occurs, no one can help the emergency person.

The technical problem of the present invention is to provide an emergency situation determination device that automatically detects an emergency situation by detecting a state of a person in real time.

Technical problem of the present invention is to determine whether the symptoms detected by analyzing the bio-signal is an abnormal symptom or an emergency situation, and an emergency situation determination device that can determine that the person is in an emergency situation by analyzing the biological signal and the operation of the hand To provide.

Provided is an emergency situation determination apparatus according to an embodiment of the present invention. The emergency situation determination device analyzes a sensor for detecting a human biosignal and a human hand within a predetermined range and the biosignal recognized by the sensor, and additionally performs a hand motion according to a result of analyzing the biosignal. The analysis unit includes a determination unit to determine whether an emergency has occurred.

As an example, when the determination unit determines that there are abnormal signs in the human body as a result of analyzing the biosignal detected by the sensor, whether the emergency occurred by analyzing the motion of the hand detected by the sensor Judge.

According to an example, the sensor detects the motion of the hand within the first and second detection ranges, and the sensor detects the movement of the hand of the person within the first detection range more than a preset number of times. In this case, the determination unit determines that an emergency has occurred, and the first detection range is narrower than the second detection range.

As an example, when the sensor detects a human hand moving more than a preset number of times from the second sensing range to the first sensing range within a preset time, the determination unit determines that an emergency has occurred.

As an example, when the sensor continuously detects a human hand within the first detection range for a preset time, the determination unit determines that an emergency has occurred.

In one example, the determination unit includes a storage unit for storing a variety of information about the symptoms occurring in the body of the person, the information is divided into information about the abnormal symptoms and information about the emergency situation.

As an example, when the bio-signals measured by the sensor match the information on the abnormality indication, the determination unit determines whether an emergency has occurred by detecting the motion of the hand.

For example, when the sensor does not detect the motion of the hand that matches the set condition during the first time, the sensor repeatedly measures the bio-signal.

By way of example, when the repeatedly measured bio-signal consistently matches the information on the abnormal signs and the sensor does not detect the motion of the hand that matches the set condition for a second time, the determination unit is an emergency It is determined that a situation has occurred, and the second time is a time longer than the first time.

As an example, when the bio-signal measured by the sensor is consistent with the information on the emergency, the determination unit determines that an emergency has occurred even though the hand motion is not detected.

By way of example, the information about the emergency includes sleep apnea symptoms of a person.

For example, when the determination unit determines that the emergency situation includes a communication unit for transmitting a message indicating that an emergency situation occurred to a predetermined emergency center or emergency center.

By way of example, after determining that the determination unit is in an emergency situation, the communication unit transmits the information about the biometric signal of a person in real time to the predetermined emergency center or the emergency center.

Provided is an emergency situation determination apparatus according to an embodiment of the present invention. The emergency determination device may be configured to determine whether an emergency has occurred as a result of analyzing a sensor for recognizing a human biosignal and a human hand motion, the biosignal or the hand motion within a predetermined range, and the determination unit. If it is determined that the additional emergency situation, and includes a communication unit for outputting a message to the outside, the determination unit analyzes the operation of the hand when it is determined that the abnormal signs occurred in the human body as a result of analyzing the biological signal.

By way of example, the determination unit includes a storage unit for storing a variety of information about the symptoms that occur in the body of the person, the data is divided into information about the abnormal signs and information about the emergency situation, for the emergency situation Information means that a greater problem has occurred in the human body than the information on the abnormal signs.

As an example, when the bio-signals measured by the sensor match the information on the abnormal symptoms, the determination unit determines whether an emergency has occurred by detecting the motion of the hand, and the sensor measured by the sensor If the biological signal is consistent with the information on the emergency, it is determined that an emergency has occurred even if the motion of the hand is not detected.

According to an example, the sensor detects the motion of the hand within the first and second detection ranges, and the sensor detects the movement of the hand of the person within the first detection range more than a preset number of times. In this case, the determination unit determines that an emergency has occurred, and the first detection range is narrower than the second detection range.

As an example, when the sensor detects a human hand moving more than a preset number of times from the second sensing range to the first sensing range within a preset time, the determination unit determines that an emergency has occurred.

By way of example, when the sensor detects the motion of the hand within the first and second detection range, the sensor continuously detects the human hand within the first detection range within a predetermined time. The determination unit determines that an emergency situation has occurred. It further includes an emergency button to notify the outside that an emergency has occurred,

By way of example, the emergency button is activated when the determination unit determines that an abnormal symptom occurs in a person.

1 is a view showing an emergency situation determination apparatus according to an embodiment of the present invention, Figure 2 is a block diagram showing an emergency situation determination apparatus according to an embodiment of the present invention.

1 and 2, the emergency situation determination device 1 may include a sensor 100, a determination unit 200, a storage unit 300, and a communication unit 400. The emergency situation determination device 1 may be a configuration or an algorithm included in the housing 10. The housing 10 may be provided with an emergency button 50 and a sensor 100. The emergency button 50 may be configured to output a message informing of an emergency through a touch operation when an emergency occurs in a human body. That is, when a person physically presses the emergency button 50, the emergency situation determination device 1 may send a message to an emergency center or an emergency center or connect a wired call with an emergency center or an emergency center. The emergency button may be activated only when the determination unit 200 determines that a person has an abnormal symptom. In this case, the emergency center may include a medical institution or an emergency room, and the emergency center may include a fire department and a police station. The housing 10 in which the emergency situation determination device 1 is embedded may be generally disposed adjacent to a place where a person takes a sleep. The sensor 100 installed in the housing 10 may determine a state of a person sleeping.

The sensor 100 may detect a biosignal of a person and an operation of the hand of the person 20 within a predetermined range. For example, the sensor 100 may be any one of an ultra-wideband communication (IR-UWB) sensor, a lidar, a frequency modulated continuous wave radar (FMCW RADAR), and a Doppler radar. Ultra-wideband communication (UWB) refers to radio technology that uses a frequency band above 500 MHz or has a value defined as non-bandwidth of 25% or more. Non-bandwidth means the bandwidth of the signal relative to the center frequency. Ultra-wideband (UWB) is a radio technology that uses a wide range of frequencies, and has various advantages such as high distance resolution, transmission, strong immunity to narrowband noise, and coexistence with other devices that share frequency. For example, the UWB has an advantage of detecting a fine movement of an object in an ultra-precision distance resolution characteristic of 1 cm or less.

IR-UWB (Impulse-Radio Ultra WideBand) radar (hereinafter referred to as UWB radar) technology is a system that combines this ultra-wideband communication (UWB) technology with radar, which has a very short duration with wide-band characteristics in the frequency domain. It refers to a radar technology that transmits an impulse signal and receives a signal reflected from an object and a person to recognize a surrounding situation. The UWB radar system generates an impulse signal having a time width of several nano-fico seconds at the signal generator and emits a wide or narrow band angle through a transmission antenna. The emitted signal is reflected by various objects or people in the environment, and the reflected signal may be converted into a digital signal through a receiving antenna and an analog-to-digital converter (ADC).

The rider may emit a laser pulse and receive the laser pulse reflected from the surrounding object to measure the distance from the lidar to the object. The lidar can sense not only the distance to the object but also the speed of the object, the shape of the object, and can be used to generate a three-dimensional image of the surrounding.

The biosignal may include at least one of a human heart rate, movement, or breathing. The sensor 100 may receive a signal reflected by a person to detect a movement of a person's chest or stomach, and thereby detect a person's heart rate or breath. In addition, the sensor 100 may detect whether or not the sleep apnea state through the human breath and the movement of the heart. Information about a person's breathing and heart movement appearing to a person in a sleep apnea state may be stored in the storage unit 300.

The sensor 100 may detect a motion of a person located within a predetermined range and a motion of the hand 20 of the person. The sensor 100 may receive a signal reflected in real time and detect a motion of a person and a motion of the hand 20 of the person. The operation of the hand 20 may include the specific shape of the hand 20 and the movement of the hand 20.

For example, the sensor 100 may detect the movement of the hand 20 moving within the detection range of the sensor 100. In this case, the movement of the hand 20 may include a change in distance between the sensor 100 and the hand 20 and a specific motion that may be represented by the hand 20.

As another example, the sensor 100 may detect a hand 20 of a person located within a detection range of the sensor 100. The sensor 100 may detect the hand 20 located within the detection range to determine a time for which the hand 20 stays within the detection range.

The determination unit 200 may determine whether an emergency has occurred by analyzing at least one or more of an operation or a biosignal of the hand 20 recognized by the sensor 100. When the determination unit 200 determines that there are abnormal signs on the body of the person as a result of analyzing the biosignal detected by the sensor 100, an emergency situation may be analyzed by analyzing the operation of the hand 20 detected by the sensor 100. It can be determined whether or not it has occurred. The determination unit 200 may determine what state a person is currently based on the information stored in the storage unit 300. The storage unit 300 may store various information about symptoms occurring in a human body. The information stored by the storage unit 300 may be divided into information on abnormal signs and information on emergency situations. That is, the information on the abnormal symptoms may include information on the abnormal symptoms and information on the emergency situation. Information about an emergency situation may mean that a greater problem has occurred in a person's body than information about abnormal symptoms. For example, the information on the emergency may include information indicating a symptom of a person not breathing, a symptom of choking during sleep, a symptom of sleep apnea, and a symptom of a poor heartbeat. That is, the information about the emergency situation may mean that a serious problem occurred in a person's body and a situation in which an emergency center and an emergency center should be contacted. For example, the information on the abnormal symptoms may include information indicating a symptom of a sudden change in the heart rate of a person, an unstable breath during sleep, and the like. That is, the information about the abnormal symptoms may mean that a problem has occurred in a person's body, but it is not necessary to contact an emergency center and an emergency center right now. Therefore, when the sensor 100 detects a symptom coinciding with the information on the abnormal symptom, the determination unit 200 may additionally detect the motion of the hand 20 of the person. When the sensor 100 detects a symptom coinciding with the information on the emergency situation, the determination unit 200 may determine that the emergency situation has occurred even without detecting the motion of the hand 20 of the person. The emergency button 50 may be activated when the bio signal detected by the sensor 100 is matched with information about an abnormal indication stored in the storage 300.

If the sensor 100 detects a bio-signal that matches the information on the abnormal signs but does not detect the motion of the hand 20 that matches the set condition within the first time, the determination unit 200 does not cause an emergency. You can judge that it is not. The setting condition may mean information on the operation of the hand 20 stored in the storage 300. That is, the setting condition may mean operations of the hand 20 that a person in an emergency situation can take. For example, the setting condition is that the hand is positioned within a detection range of the sensor 100 for a specific time or to take a specific operation through the hand 20 within the detection range of the sensor 100 or the detection range of the sensor 100. It may include moving the hand 20 a predetermined number of times at the boundary of. When the sensor 100 does not detect the motion of the hand 20 that matches the set condition within the first time, the sensor 100 may repeatedly measure the biosignal of the person. If the repeatedly measured bio-signal consistently matches the information on the abnormal symptoms and the sensor 100 does not detect the motion of the hand 20 that matches the set condition within the second time, the determination unit 200 is an emergency It can be determined that the situation has occurred. The second time may mean a time longer than the first time. If the biosignal detected by the sensor 100 matches the information on the abnormal signs, but the abnormal signs are generated in the person for a long time, serious damage may occur to the human body. In contrast, if the abnormal symptoms are detected only for a short time, serious problems may not occur in the human body. Therefore, the determination unit 200 may determine that an emergency situation has occurred when the biological signal of the person continuously measured for the second time is consistent with the information on the abnormal symptom.

The storage unit 300 may store various information about symptoms occurring in a human body. The information stored by the storage unit 300 may be divided into information on abnormal signs and information on emergency situations. In addition, the storage unit 300 may set and store conditions recognizable as an emergency among the operations of the hand 20 that a person may take. In addition, the storage unit 300 may store specific operations of the hand 20 and a specific shape of the hand 20 as setting conditions.

When determining that the determination unit 200 is an emergency, the communication unit 400 may transmit a message indicating that an emergency has occurred to a predetermined emergency center or emergency center. In addition, the communication unit 400 may connect a wired call to a predetermined emergency center or emergency center. After determining that the determination unit 200 is in an emergency situation, the communication unit 400 may transmit information about a human biosignal to a predetermined emergency center or emergency center in real time. Through this, the status of a person in an emergency situation can be transmitted to the emergency center, emergency center or rescue personnel in real time.

According to an embodiment of the present invention, the emergency situation determination device 1 may determine the current emergency situation by detecting the current state of a person. The emergency situation determination device 1 may distinguish between a case where a person can directly send a rescue signal or perform a rescue call and a case where a person cannot directly send a rescue signal or perform a rescue call. Through this, the emergency situation determination device 1 may contact the emergency center or emergency center on behalf of the person in an emergency situation.

In addition, according to an embodiment of the present invention, the emergency situation determination device 1 may detect various symptoms that may occur in a person to distinguish whether the currently detected symptom is a symptom for an abnormal symptom or an emergency situation. Through this, it can be prevented to send the rescue request to the emergency center or emergency center indiscriminately.

In addition, according to the embodiment of the present invention, the emergency situation determination device 1 may automatically contact the emergency center or emergency center by detecting an emergency situation occurring during sleep of a person.

3 is a block diagram illustrating a storage unit according to an exemplary embodiment of the present invention. Duplicate descriptions are omitted for simplicity of explanation.

1 to 3, the storage unit 300 may store various information on symptoms occurring in a human body and setting conditions indicating an emergency situation. The various pieces of information may include information about an abnormal symptom that may occur to a person and information about an emergency situation.

For example, the storage unit 300 may include first information 300a, second information 300b, n-th information 300n-1, and n-th information. The first information 300a may include one information of the information on the abnormal symptom, the second information 300b may include one information of the information on the emergency situation, and the n-1 information ( 300n-1 may include a specific operation of the hand 20 of the person meaning an emergency, and the nth information 300n may include a movement of the hand 20 of the person meaning an emergency. .

The determination unit 200 may determine that among the information stored in the storage unit 300, the bio signal detected by the sensor 100 and information corresponding to the operation of the hand 20 are determined. The determination unit 200 may determine the current state of the person based on information corresponding to the biosignal and the operation of the hand 20.

4 is a block diagram illustrating a communication form of a communication unit according to an embodiment of the present invention.

2 and 4, the communication unit 400 may transmit a message indicating that an emergency situation has occurred directly to the emergency center 600 or connect a wired call. The communication unit 400 may transmit a message or connect a wired call to the emergency center 600 without a separate intermediate server. The communication unit 400 may transmit information on the biosignal, which may know the current state of the person, to the emergency center 600.

In addition, the communication unit 400 may transmit a message indicating that an emergency situation has occurred or connect a wired call to the emergency center 600 through the server 500. In this case, the server 500 may transmit a result of analyzing the biosignal detected by the sensor 100 and personal information of the person to the emergency center 600.

5 is a view for explaining an example of detecting a human hand motion according to an embodiment of the present invention. Duplicate descriptions are omitted for simplicity of explanation.

2 and 5, the sensor 100 may detect the movement of the hand 20 located within the detection range. The determination unit 200 may analyze the operation of the hand 20 when the biosignal corresponding to the information on the abnormal indication is detected by the sensor 100. The sensing range of the sensor 100 may include a first sensing range D1 and a second sensing range D2. The first sensing range D1 and the second sensing range D2 may not overlap. The hand 20 may move between the first sensing range D1 and the second sensing range D2. A person in an emergency may stir hand 20 toward sensor 100. In this case, the hand 20 may be located in the first detection range D1 of the sensor 100, and may also be located in the second detection range D2.

For example, the determination unit 200 may determine that an emergency has occurred when the movement of the hand 20 is detected by the sensor 100 more than a predetermined number of times in the first detection range D1. The hand 20 may be located within the first sensing range D1 and move out of the first sensing range D1. That is, the sensor 100 may measure the number of times the hand 20 is detected within the first detection range D1 for a specific time as the person performs the action of swiping the hand 20. When the hand 20 is detected within the first detection range D1 for a predetermined number of times or more during a specific time, the determination unit 200 may determine that an emergency has occurred to a person.

As another example, the determination unit 200 detects that the sensor 100 moves the human hand 20 more than a predetermined number of times from the second detection range D2 to the first detection range D1 within a preset time. In this case, the determination unit 200 may determine that an emergency has occurred. That is, the sensor 100 may measure the number of times the hand 20 moves from the second sensing range D2 to the first sensing range D1 for a specific time by an action of a person swiping the hand 20. .

Operations of the hand 20 described in the above examples may be stored in the storage unit 300 as a set condition.

6 is a view for explaining another example of detecting a human hand motion according to an embodiment of the present invention. Duplicate descriptions are omitted for simplicity of explanation.

2 and 6, the sensor 100 may detect whether the hand 20 is within a sensing range of the first sensing range D1 or the second sensing range D2. For example, the determination unit 200 may determine that an emergency has occurred when the sensor 100 continuously detects the hand 20 within the first detection range D1 for a preset time. When an emergency situation occurs, a person may reach out toward the sensor 100. When the hand is extended toward the sensor 100, the hand 20 may be detected within the first detection range D1. The first detection range D1 may refer to a range in which a person intentionally extends the hand 20 toward the sensor 100 to be detected by the sensor 100. In addition, the preset time may refer to a time when the hand 20 of the human being is hard to be continuously detected in everyday life. Accordingly, the determination unit 200 may recognize that an abnormal situation occurs when the hand 20 is detected for a preset time within the first detection range D1. The determination unit 200 may analyze the operation of the hand 20 when the biosignal corresponding to the information on the abnormal indication is detected by the sensor 100.

7 is a flowchart illustrating a method of determining an emergency situation according to an embodiment of the present invention. Duplicate descriptions are omitted for simplicity of explanation.

Referring to FIG. 7, the sensor may detect a biosignal of a person. The sensor may be disposed in a place adjacent to a person, and preferably, may be installed adjacent to a place where a person takes a sleep (S100).

The determination unit may determine the human state by analyzing the biosignal detected by the sensor. The determination unit may match information on various symptoms that may occur to the person stored in the storage unit with the biosignal detected by the sensor. Through this, the determination unit may determine what the biosignals sensed by the sensor mean, and analyze the biosignals to determine whether a symptom generated in a person relates to an abnormal symptom or an emergency situation (S200).

The determination unit may determine whether the bio-signals match information on abnormality information or information on emergency situations. If the biological signal does not match the information on the abnormal symptoms and information on the emergency situation, the determination unit may determine that the state of the person is a stable state (S300).

When the biological signal matches the information on the abnormality sign, the determination unit may analyze the motion of the hand (S400 and S500).

However, when the biological signal does not match the information on the abnormal signs, the biological signal is consistent with the information on the emergency situation, so the determination unit may determine that the human condition is in an emergency. In this case, the communication unit may notify the outside that an emergency situation has occurred (S700).

When the biosignal coincides with the information on the abnormal symptom, the determination unit may determine whether the hand operation matches the setting condition. The setting condition may include information about the operation of the hand of the person who can recognize the emergency situation. That is, the determination unit may determine whether a person wants a rescue request by analyzing the motion of the hand. If the motion of the hand does not match the set condition, the sensor may repeatedly detect a human biosignal. The sensor may detect a human bio signal in real time, and the determination unit may analyze the bio signal in real time. However, even when the operation of the hand does not match the set condition, if the detection of the bio-signal matching the information on the abnormal signs in the person for a predetermined time or more, the determination unit may determine that the emergency has occurred in the person (S600).

When the determination unit determines that an emergency situation has occurred, the communication unit may notify the outside that an emergency situation has occurred (S700).
