1 is a block diagram of a user emergency notification apparatus based on a biosignal according to an embodiment of the present invention.

Referring to FIG. 1, the user emergency notification device 100 based on a biosignal according to an embodiment of the present invention may include a biosensor 110, a microcontroller 120, a microphone 130, and an antenna unit 140. It may include.

First, the biosensor 110 detects a user's biosignal. Here, the biological signal may include brain waves, heart rate, blood pressure, body temperature, or muscle tension contraction force.

In order to detect these biosignals, the biosensor 110 may include an EEG sensor, a heart rate sensor, an electrocardiogram sensor, a blood pressure sensor, a body temperature sensor, and the like. In particular, by applying the PCC (Personal Car Communication) function applied to the vehicle key of the Volvo car recently to the heart rate sensor, it is also possible to remotely detect the heart rate or to check the presence of strangers other than the user. In addition, an electromyograph (EMG) can also be used to measure tension contraction of muscles. The command to contract muscles is transmitted from the brain to the muscles through the spinal cord and peripheral motor nerves, which are composed of electrical signals, and the body's combination of signals causes the muscles to contract and move in harmony. The EMG can detect and plot the electrical signals as the muscles move.

The biosensor 110 may be configured to be attached in a manner of contacting the user's body, particularly the skin, in order to detect the user's biosignal.

The present invention transmits the sensing data sensed through the biosensor 110 to the microcontroller, which transmits the sensing data to the microcontroller 120 in real time, or to the microcontroller 120 at regular time intervals, Only when there is a change in the user's sensing data can be transmitted to the microcontroller 120, which can of course be variously applied according to the user's settings.

On the other hand, the microphone 130 receives the ambient voice signal according to the command of the microcontroller 120, converts it into a digital signal and transmits it to the antenna unit 140. The microphone 130 may be connected to an analog-to-digital converter to convert ambient voice signals into digital signals.

In addition, when the micro controller 120 receives the sensing data sensed and transmitted from the biosensor 110, and the sensing data having a value equal to or greater than a specific threshold set by the user is transmitted from the biosensor 110. The operation command signal is transmitted to the microphone 130 and the antenna unit 140, respectively.

This is because, when the user is in an emergency situation, a sudden change in the biosignal occurs, so that the sensing data value corresponding to the biosignal having a value greater than or equal to the specific threshold is detected from the biosensor 110 and thus the microcontroller 120. The microcontroller 120 determines that this is an emergency situation and transmits an operation command to the microphone 130 and the antenna unit 140. The microcontroller 120 may transmit a location signal and a surrounding voice signal for a user to an external access point (AP) when the measured value of the biosignal exceeds a predetermined threshold.

In FIG. 1, an external user terminal 190 may be an AP or another user's mobile phone, PDA, notebook computer, or the like.

When the microphone 130 and the antenna unit 140 are always set in an operating state, the power supply unit 150 always supplies power to the microphone 130 and the antenna unit 140, and thus the power supply unit 150. ) Life will be shortened.

On the other hand, if the microphone 130 and the antenna unit 140 is always set to an operating state, although the user's location and voice may be transmitted in real time to the terminal 190 of the external user monitoring the emergency situation of the user, When configured in this way, an external user may not immediately grasp whether or not an emergency situation of the user occurs.

Therefore, when the sensing data value corresponding to the biosignal having a value equal to or greater than the specific threshold value is detected from the biosensor 110 and received by the microcontroller 120, the microcontroller 120 includes the microphone 130 and the antenna. The unit 140 is operated, and an external user can grasp the voice signal and the location of the user transmitted from the antenna, determine whether the user has an emergency situation, and track the occurrence point of the situation from the location. .

Meanwhile, the microcontroller 120 may be preset based on the average sensing data of the user in order to set a specific threshold value of the sensing data of the biosensor, and when the sensing data value of the biosensor is received at a predetermined cycle. The threshold value may be set based on a difference value with the sensing data received immediately before.

The power supply unit 150 supplies power to the microcontroller and also supplies power to the microphone and the antenna unit according to a command of the microcontroller. The power supply unit 150 may include a rechargeable battery in consideration of portability.

On the other hand, the user emergency situation notification device 100 based on the bio-signal is connected to the navigation kit and a Bluetooth signal existing in a specific distance from the user and the terminal of the external user to perform a predetermined monitoring of the terminal information of the navigation kit It may further include a Bluetooth module for transmitting to the terminal 190.

In fact, when the user is in an emergency situation such as kidnapping or abduction, the user emergency situation notification device 100 based on the biosignal according to an embodiment of the present invention, with reference to statistical information that the criminal uses a transportation means such as a car. The built-in Bluetooth module allows to transmit the traffic information of the offender to the terminal 190 of the external user that serves as a pre-scheduled monitoring.

In this regard, since most of the means of transportation including a vehicle includes a navigation kit, and the navigation kit supports most of Bluetooth functions, a Bluetooth module is provided to the user emergency notification device 100 based on a biosignal according to the present invention. By providing a Bluetooth connection with the navigation kit existing in a certain distance from the user in danger, by sending the terminal information of the Bluetooth connected navigation kit to the terminal 190 of a predetermined external user to track the identity of the criminal do.

That is, when not in a dangerous situation, even if a Bluetooth connection is established, the microcontroller 120 does not command operation to the microphone and the antenna unit, so that the terminal information of the navigation kit is not transmitted, and unnecessary information is not transmitted to the external user. Will not.

For reference, in order to be able to send and receive calls or data to and from each other using a Bluetooth device, a connection process is required between devices, and this connection process is largely an Inquiry step, a paging step, and a Connection step. This is done.

The enquiry step searches for a Bluetooth device (connection target device) located within a wireless communication range of the Bluetooth device (user Bluetooth device), that is, within a radio wave coverage range, and obtains various information from each connection target device, that is, each connection target. The name and address of the device are collected to output a list of connection target devices found through the display unit of the user's Bluetooth device, for example, an LCD (Liquid Crystal Display).

In the paging step, when the user Bluetooth device selects a desired device from among the connection target devices searched through the inquiring step and attempts to connect, the user Bluetooth device transmits a paging packet including the address of the selected connection target device. The connection target device receiving the packet responds by transmitting a paging response packet to the device and performs a connection between the two devices. At this time, verify that the device is available and authenticate to connect.

The connection phase is then connected between the two devices to perform functions, such as communication and transmission and reception of various data.

On the other hand, the user emergency situation notification device 100 based on the bio-signal according to the present invention may further include an active type RFID tag electrically connected to the power supply.

The active type RFID tag can transmit the location signal of the user to the mobile phone when the mobile phone is operating, and can transmit and receive the location signal of the user through an external RFID reader when the mobile phone is not operating. have.

To this end, the RFID reader can be installed based on the main activity radius in the user's actual living environment, and the passive RFID tag has a short operating distance, so the active type RFID tag is notified to the user emergency based on the biosignal according to the present invention. It may be provided in the device 100.

In implementing the real-time location information service, it is possible to utilize the 2.4GHz-based frequency band, the infrastructure for detecting the signal may include an AP. In addition, in the case of embedding the RFID tag in the user emergency notification device 100, the infrastructure for detecting a signal is arranged for each zone to actively read the information of the RFID tag embedded in the user emergency notification device 100. It may include an RFID reader. In some cases, a combination of the AP and the RFID reader may be used.

The AP receives a location signal transmitted by the user emergency notification device 100 and calculates a location of the user emergency notification device 100 therefrom. The location signal may include unique identifier information of the user emergency notification device 100. The AP may exchange information by being connected to another user's terminal by wire or wireless. The AP may be a form in which a location tracking function according to the present invention is added to an WiFi access point or a WiBro base station. Like the mobile communication base station, the AP is preferably installed in a predetermined area unit.

As a method of locating the user emergency notification device 100, a Received Signal Strength Intensity (RSSI) method using a received signal strength and a Time of Arrival (TOA) method using a time taken for a signal to be transmitted between devices, By using the TDOA (Time Difference of Arrival) method using the difference in flight time of high radio waves, the Angle of Arrival (AOA) method using the arrival angle of radio waves, or the Phase of Arrival (POA) method using the arrival phase of radio waves, etc. It can be compatible with hardware infrastructures that provide the same approach.

Among these, in particular, a distance measuring method using RSSI is used by measuring the signal strength of a wireless mobile device or a tag received from an AP, and the signal is moved by a power loss or a path loss of a signal between the tag and the AP. It's a way to connect with a distance. In addition, the distance measuring method using the TOA is to measure the time it takes for the signal to be transmitted between the tag and the AP, converts it into a distance and uses it for position estimation. The distance measuring method using TDOA measures the time difference between signal transmission between a tag and an AP, converts it to a distance, and uses it for position estimation. That is, the position of the tag is calculated by using points where the flight time difference between the two APs and the tag is constant.
