Abstract

An emergency notification system and server are provided. The emergency notification system includes a wearable device that senses biosignals of a user wearing the wearable device and captures environment data; and a mobile device that periodically receives at least one of the biosignals and the environment data from the wearable device, determines a distance between the mobile device and the wearable device, periodically transmits the at least one of the biosignals and the environment data to a server, requests the wearable device to provide the at least one of the biosignals and the environment data, and transmits the received at least one of the biosignals and the environment data to the server.

Claims

1. An emergency notification system comprising:

a wearable device that senses biosignals of a user wearing the wearable device and captures environment data; and

a mobile device, which is wirelessly connected to the wearable device, that periodically receives at least one of the biosignals and the environment data from the wearable device, determines a distance between the mobile device and the wearable device based on an intensity of an adjacent signal received from the wearable device, periodically transmits the at least one of the biosignals and the environment data to a server, requests the wearable device to provide the at least one of the biosignals and the environment data, and transmits global positioning system (GPS) information and the received at least one of the biosignals and the environment data to the server when the intensity of the adjacent signal is less than or equal to a preset value or when an emergency signal is received from the server,

wherein the environment data comprises at least one of an image and a sound.

2. The system of claim 1, wherein the wearable device comprises:

a biosensor unit that senses the biosignals of the user;

an adjacent signal transmission unit that generates the adjacent signal;

a data communication unit that wirelessly transmits the biosignals and the environment data to the mobile device; and

a control unit that activates the biosensor unit, when a request for the biosignals is received from the mobile device.

3. The system of claim 2, wherein the wearable device further comprises a GPS reception unit that receives a GPS signal from a satellite.

4. The system of claim 3, wherein the wearable device generates GPS information of a current position, based on the received GPS signal, and periodically transmits the GPS information to the mobile device.

5. The system of claim 2, wherein the wearable device further comprises a speaker that outputs a help request signal, when the emergency signal is received from the mobile device.

6. The system of claim 2, wherein the biosensor unit measures at least one of an electrocardiogram, blood pressure, body temperature, and respiration volume.

7. The system of claim 1, wherein the wearable device periodically transmits the at least one of the biosignals and the data to the mobile device.

8. The system of claim 1, wherein the wearable device comprises at least one of an imaging device that captures the image, and a microphone that senses the sound.

9. The system of claim 1, wherein the mobile device receives the biosignals and determines whether an emergency situation has occurred, based on the received biosignals.

10. The system of claim 9, wherein the mobile device transmits an emergency notification message to a second mobile device, when the emergency situation has occurred.

11. The system of claim 1, wherein the mobile device provides the at least one of the biosignals and the environment data to a second mobile device.

12. An emergency notification server comprising:

a transceiver that periodically receives, from a first mobile device, biosignals and an intensity of an adjacent signal between the first mobile device and a wearable device that senses the biosignals; and

a controller that determines whether an emergency situation has occurred based on the received biosignals, generates an emergency signal requesting the first mobile device to provide data comprising a most recently received sound, an image, and global positioning system (GPS) information when the intensity of the adjacent signal is less than or equal to a preset value or when the emergency situation has occurred, and controls the transceiver to transmit the emergency signal to the first mobile device or to transmit the emergency signal and the data to a second mobile device.

13. The server of claim 12, further comprising a receiver database (DB) that stores information about a receiver group for receiving the emergency signal.

14. A mobile device that is wirelessly connected to a wearable device, the mobile device comprising:

a transceiver that periodically receives, from the wearable device, at least one of biosignals sensed by the wearable device and environment data captured by the wearable device, and that periodically transmits the received at least one of the biosignals and the environment data to a server; and

a controller that requests the wearable device to provide the at least one of the biosignals and the environment data, determines whether an emergency situation has occurred, based on the received at least one of the biosignals and the environment data, transmits global positioning system (GPS) information to a server when an intensity of an adjacent signal received from the wearable device is less than or equal to a preset value or when an emergency signal is received from the server, and controls the transceiver to transmit an emergency signal to the wearable device, when the emergency situation has occurred,

wherein the environment data comprises at least one of an image and a sound of a current environment of the wearable device.

15. The mobile device of claim 14, further comprising an adjacent signal reception unit that determines a distance between the mobile device and the wearable device based on an intensity of the adjacent signal generated by the wearable device.

16. The mobile device of claim 15, wherein the controller controls the transceiver to transmit the received at least one of the biosignals and the environment data to the server, when the intensity of the adjacent signal is less than or equal to a preset value or when the emergency signal is received from the server.

17. The mobile device of claim 14, wherein the controller controls the transceiver to transmit an emergency notification to a receiver group, when the emergency situation has occurred.

18. The mobile device of claim 17, wherein the receiver group comprises at least one of a guardian of a user wearing the wearable device and an emergency agency.
