As shown in FIG. 2, the monitoring terminal 100 according to an embodiment of the present invention may include a biosignal measuring unit 110, a behavior pattern measuring unit 120, an emergency state determination unit 130, a control unit 140, The wireless communication unit 150 and the GPS unit 160 is included. Here, the monitoring terminal 100 is a portable terminal, but a configuration for supplying power by using a battery is mounted. However, these matters are well known in the art, and thus will not be described in detail.

In FIG. 2, the biosignal measuring unit 110 according to an exemplary embodiment of the present invention includes a touch sensor 111, an oxygen saturation sensor 112, a temperature sensor 113, and the like. In addition, FIG. 2 shows that the behavior pattern measurer 120 according to the embodiment of the present invention includes an acceleration sensor 121 and a behavior pattern information generator 122.

As shown in FIG. 2, the biosignal measuring unit 110 measures the biosignal measured from a plurality of sensors (ie, a touch sensor, an oxygen saturation sensor, a temperature sensor, etc.) for measuring a biosignal of a subject. Send to 130.

In this case, the touch sensor 111 generates an effective signal (for example, a high signal of a digital signal) when the monitoring terminal 100 is in close contact with the body of the subject and comes into contact with the skin of the subject. Transmit to the determination unit 130. That is, the touch sensor 111 is a sensor that detects whether or not the subject wears the monitoring terminal 100.

The oxygen saturation sensor 112 is a photoplethysmography (PPG) sensor, and the PPG sensor measures light intensity reflected or transmitted after the light source is incident on the skin of the subject (in particular, the ankle skin of the subject in the embodiment of the present invention). Measure

The temperature sensor 113 measures the body temperature of the subject to be transmitted to the emergency state determination unit 130.

The behavior pattern measuring unit 120 measures the activity of the subject. To this end, the behavior pattern measurer 120 includes an acceleration sensor 121 and a behavior pattern information generator 122, and the movement state and / or movement of the subject using the result measured by the acceleration sensor 121. Generates behavior pattern information to determine the speed, and transmits the generated behavior pattern information to the emergency state determination unit 130.

Specifically, the acceleration sensor 121 measures the force (for example, gravity, movement, etc.) acting on the monitoring terminal 100 according to the movement of the subject over time to the behavior pattern information generation unit 122. send.

In the embodiment of the present invention, the acceleration sensor 121 of the behavior pattern measuring unit 120, as shown in Figure 3 (b), using the coordinate values of the three coordinate axes that are perpendicular to the movement of the subject It was shown that it is a three-axis acceleration sensor that can measure.

At this time, (b) of Figure 3, when the monitoring terminal 100, that is, the main body 100a according to an embodiment of the present invention, as shown in Figure 3 (b), when mounted on the ankle of the subject, the acceleration sensor ( The force applied to the subject's up / down (i.e., up / down) through the Y axis of 121) and the force applied to the front / rear (i.e., front / rear) of the subject through the X-axis. , Z-axis to measure the force applied to the left / right (ie right / left) of the subject.

The behavior pattern information generation unit 122 analyzes the movement state and the movement speed of the subject based on the force acting on each coordinate axis measured by the acceleration sensor 121, and sets a reference time based on the analyzed information. Behavior pattern information indicating the movement state and the movement speed in units of (30 seconds, 1 minute, etc.) is generated and transmitted to the emergency state determination unit 130.

Specifically, the behavior pattern information generation unit 122 is based on the change in the coordinate values (up and down values) of the Y-axis of the acceleration sensor 121, that is, the stationary state (eg, standing state, sitting) Measure the presence, lying state, and movement state (eg, walking state, running state, etc.) and / or speed of movement.

An example of the output of the acceleration sensor 121 input to the behavior pattern information generator 122 is illustrated in FIG. 4.

In FIG. 4, (a) the graph shows coordinate values of three axes of the acceleration sensor 121 in a state where the subject stands, and (b) the graph shows three axes of the acceleration sensor 121 in a sitting stationary state. The coordinate values are shown over time, and (c) the graph shows the coordinate values of three axes of the acceleration sensor 121 over time while the subject is walking.

As shown in FIG. 5, the behavior pattern information generator 122 obtains peak data on the Y-axis with respect to the output of the acceleration sensor 121 input as shown in FIG. 4. That is, the behavior pattern information generation unit 122 detects the peak value through the derivative as shown in FIG. 5B with respect to the Y-axis data input as shown in FIG. 5A.

If only the peak value is detected in this manner, the interval d between the peak value and the peak value can be obtained as shown in FIG.

The behavior pattern information generation unit 122 that obtains a graph of the peak value generates an behavior pattern based on a predetermined reference time (for example, 30 seconds, 1 minute, etc.) and provides the behavior pattern to the emergency state determination unit 130.

The emergency state determination unit 130 receives the information provided from the biosignal measurement unit 110 and the behavior pattern information generation unit 122, and analyzes the output of each sensor and analyzes the monitoring information of the central management server 200. To provide. In addition, the emergency state determination unit 130 determines an emergency state or a transient state by analyzing the output of each sensor and performs an operation corresponding to the emergency state or the transient state.

The emergency state determination unit 130 generates an emergency state notification message and transmits the generated emergency state notification message to the controller 140 when an emergency state occurs. For reference, the emergency status notification message includes at least one information of the biosignal information and the behavior pattern information and the emergency status identifier. In this case, the biosignal information includes at least one of the most recently measured oxygen saturation information, heart rate information, and body temperature information, and the behavior pattern information includes information on the current movement state of the subject and / or the movement speed information. .

The emergency state determination unit 130 determines whether to be worn by the output of the touch sensor 111, and calculates the body temperature by the output of the temperature sensor 112.

The emergency state determination unit 130 compares the output of the oxygen saturation sensor 112 (that is, the oxygen saturation degree) with a set reference value to determine whether to breathe and counts the breathing to calculate the heart rate. The body temperature and heart rate are compared with each reference value (hereinafter, referred to as an “emergency reference value”) to determine whether there is an emergency state. That is, the emergency state determination unit 130 indicates that an emergency condition occurs when the currently measured oxygen saturation has a value less than the preset reference oxygen saturation, and the heart rate has a value greater than or less than the preset reference heart rate. To judge. In addition, the emergency state determination unit 130 determines that an emergency condition occurs when the body temperature of the subject received through the temperature sensor 113 has a value above or below the preset reference body temperature.

For reference, the reference oxygen saturation, reference heart rate, and reference body temperature may be set based on the normal normal oxygen saturation of the subject, heart rate, body temperature, and medical safety standard.

In addition, the emergency state determination unit 130 analyzes the behavior pattern output from the behavior pattern information generation unit 122 to determine the state of the subject and the transient state. The emergency state determination unit 130 stores the basic pattern and the transient state threshold value for each state of the subject tested on the subject in order to determine the state of the fitz sperm and the transient state.

The condition of the subject is as follows.

Emergency state determination unit 130 as shown in the graph (a), (b), (c) of Figure 4 the value of the force acting on the Y axis of the acceleration sensor 121 (that is, the peak value of the Y-axis coordinates) According to the classification, the stationary state or moving state.

Stationary states are standing, sitting, and lying down.

The stationary state is a state in which the value of each axis has little change over time.

However, the standing or sitting state causes the Y axis to face down, ie downward. In this case, 1 g (gravity value) of gravity is applied to the Y axis (eg, Y axis value = -1 g). In the lying state, however, gravity is not applied to the Y axis (eg Y axis value = 0).

Therefore, when the coordinate value of the Y axis does not change over time, the emergency state determination unit 130 determines that the subject is standing or sitting, and determines that it is lying when there is no value. Of course, if you are standing, you are moving forward or backward, so the initial change in the waveform of the X-axis occurs, and the sitting force moves downward while standing, so there is little difference in the waveform of the X-axis. Almost the same except for these initial changes.

On the other hand, the moving state includes a walking state and a running state.

In the graph of FIG. 4C, the 3-axis coordinate values of the acceleration sensor 121 are shown as time passes when the subject is walking or running. In this case, as shown in the graph (c) of FIG. 4, when the Y-axis coordinate value of the acceleration sensor 121 changes with time, the emergency state determination unit 130 determines the state of the subject as an operation state.

In addition, the emergency state determination unit 130 determines whether the subject is walking or running by using the interval d between the peak value of the Y axis and the peak value of the acceleration sensor 121. The peak value is the gravitational force acting on the subject, that is, the degree of force exerted by the subject, and the interval d means stride length.

Here, the emergency state determination unit 130 stores basic pattern information about the peak value of the Y-axis and the interval d during normal stride (walking) obtained by experimenting with the subject.

Therefore, the emergency state determination unit 130 compares the peak value in the behavior pattern provided by the behavior pattern information generation unit 122 with the peak value of the basic pattern information, and determines the interval d within the set time in the received behavior pattern. The number of times is compared with the number of intervals within the set time in the basic pattern information. Here, the number of intervals d within the set time may be converted into a speed.

If it is larger than the peak value of the basic pattern and the number of intervals is large, the emergency state determination unit 130 determines that the subject is running.

On the other hand, the emergency state determination unit 130 measures the amount of activity.

Activity measurements are based on peak values of behavior patterns. The emergency state determination unit 130 accumulates and calculates a peak value of the behavior pattern, and when the measured activity amount is greater than or equal to the transient state threshold, it is called a transient state. For example, compared with the amount of activity in the state where the subject is running and the amount of activity in the state of walking, the state of running is greater than the state in which the peak is walking and the number of peaks appears within the set time, so that the state of walking is It is higher than the amount of activity.

The transient state is a situation in which the subject is working excessively and is in a physical state that is difficult for the subject to endure.

Here, the emergency state determination unit 130 uses the peak value in the continuous walking or running situation in calculating the amount of activity. That is, the emergency state determination unit 130 does not accumulate the peak value any more when the behavior pattern becomes a standing state such as standing, sitting or lying down, while calculating and calculating the peak value. That is, stop. When the subject runs or walks again, the previously calculated activity is reset and new activity is calculated. Of course, the emergency state determination unit 130 checks the duration of the subject's stationary state (ie, standing, sitting, lying down), and the total peak previously calculated when the subject exceeds the reference time determined to be sufficiently rested. The value is reset, and if not, the total peak value is calculated by accumulating the peak value of the new running or walking state on the previously calculated total peak value.

Emergency state determination unit 130 provides the total peak value as the monitoring information to the central management server (200).

In the above, it has been described that the emergency state determination unit 130 determines the emergency state for each of the biological signals, that is, parameters such as oxygen saturation, heart rate, and body temperature. At this time, the emergency state determination unit 130 according to an embodiment of the present invention when it is determined that at least one of the bio-signals of each of the bio-signals has a value other than a predetermined reference range value or all of the bio-signals When it is determined to have a value other than the set reference range value, it may be determined that an emergency condition has occurred.

For reference, the emergency state determination unit 130 determines that the measurement of the biosignal is started when the valid signal is received through the touch sensor 111 of the biosignal measurement unit 110 and then uses the received biosignals to provide an emergency. Determination processing for the occurrence of a state can be started.

Meanwhile, the emergency state determination unit 130 determines the emergency warning situation by using the behavioral signal information received through the biosignal and the behavioral pattern measurement unit 120 measured by the biosignal measurement unit 110. In addition, when it is determined that an emergency warning situation occurs, the emergency state determination unit 130 generates an emergency warning notification message and transmits it to the control unit 140. For reference, the emergency alert notification message includes at least one of the biosignal information and the behavior pattern information and the emergency alert identifier. At this time, the emergency warning situation is a step for warning the subject to be aware of the current state as a situation distinguished from the emergency condition.

In detail, the emergency state determination unit 130 compares each biosignal received from the biosignal measurement unit 110 with respective reference values (hereinafter, referred to as “alert reference values”). For reference, the warning reference value is a reference value different from the emergency reference value, and the warning reference value is a level of the degree of concern (that is, transient state) that an emergency condition is concerned based on the usual normal biosignal and behavior pattern of the subject. It can be set to a value.

In this case, the emergency state determination unit 130 determines that at least one of the bio-signals has a value outside the warning reference value range, or that each of the bio-signals is outside the range of the preset warning reference value. When it is determined to have an emergency warning situation can be determined. That is, if the oxygen saturation and heart rate of the subject are measured to a level that is concerned about the occurrence of an emergency condition, it is determined as an emergency warning situation.

In addition, the emergency state determination unit 130 compares the movement speed received from the behavior pattern measurement unit 120 with a predetermined reference speed. In addition, the emergency state determination unit 130 determines that an emergency warning situation occurs when a movement speed received within a predetermined time exceeds the reference speed or when the received movement speed exceeds the reference speed and continues for a preset reference period. do. That is, it is determined as an emergency warning situation in which an emergency condition may occur when the subject runs or walks above the reference speed, or walks or runs above the reference speed by more than the reference time.

Emergency state determination unit 130 according to an embodiment of the present invention is when the at least one bio-signal or all of the bio-signals of each of the bio-signal has a value outside the range of the emergency warning value and the behavior pattern corresponds to the emergency warning situation Can be determined to have an emergency warning situation.

Meanwhile, the emergency state determination unit 130 generates a health monitoring information message periodically and transmits the generated health monitoring information message to the control unit 140 in an emergency state or an emergency warning state (that is, a normal situation). For reference, the health monitoring information message includes at least one of the measured biosignal information and behavior pattern information, a monitoring identifier, and the like.

The controller 140 receives an emergency status notification message, an emergency warning notification message, and a health monitoring information message, and checks an identifier included in the corresponding message. Then, the controller 140 adds the subject identification information to each message and transmits it to the central management server 200 through the wireless communication unit 150. For reference, the subject identification information may be an identification number donated to the subject or a terminal identification number donated to the monitoring terminal 100.

In addition, the controller 140 outputs an emergency alert through a display screen (not shown) and a speaker (not shown) provided in the monitoring terminal 100 itself when the identifier checked in the received message is an emergency alert identifier. For reference, the controller 140 may output the emergency warning text on a liquid crystal screen (not shown) as a text or as an alarm sound through a speaker (not shown).

The wireless communication unit 150 connects to a wireless communication network such as a mobile communication network or a local area network according to a control signal of the control unit 140 to transmit an emergency status notification message, an emergency warning notification message or a health monitoring information message to an external device such as the central management server 200. To send.

The GPS unit 160 grasps the current position of the monitoring terminal 100 and provides the control unit 140 to be included in the monitoring information message or emergency status notification message and transient status notification message provided to the central management server 200. do.

On the other hand, it has been described above that the monitoring terminal 100 according to an embodiment of the present invention generates an emergency status notification message and an emergency warning notification message by determining an emergency condition and an emergency warning situation by itself.

However, the monitoring terminal 100 according to another embodiment of the present invention measures the biosignal and behavior pattern of the subject to generate and wirelessly transmit a health monitoring information message, and transmits an emergency from an external (for example, central management server). It is also possible to receive status notification messages or emergency alert situation messages wirelessly.
