1. An emergency alert system comprising:
- an alert device for generating a first alert signal including identification information stored in advance when a signal-generating-button click signal is sensed, and transmitting the first alert signal by using a local wireless communication protocol;
a relay device for receiving the first alert signal, extracting the identification information from the first alert signal, generating a second alert signal including the identification information and location information of the relay device, and transmitting the second alert signal by a predetermined dedicated wireless protocol in which a common channel of a specific frequency band assigned to transmit and receive urgent wireless signals to and from an emergency services organization is set; and
a security device for receiving the second alert signal from the relay device by using the dedicated wireless protocol,wherein the relay device is positioned at a region where it is capable of communication with the alert device by using the local wireless communication protocol.

Abstract
An emergency alert system includes an alert device, a relay device, and a security device. When a signal-generating-button click signal is sensed, the alert device generates a first alert signal including identification information stored in advance, and transmits the first alert signal to the relay device by using a local wireless communication protocol. The relay device receives the first alert signal from the alert device, extracts the identification information, generates a second alert signal including the identification information and location information of the relay device, and transmits the second alert signal to the security device by using a preset dedicated wireless protocol.

7. An emergency alert method comprising:
-
receiving, by a relay device, a first alert signal, wherein the relay device is positioned at a region where it is capable of communication with an alert device by using a local wireless communication protocol and generates the first alert signal including identification information stored in advance when a signal-generating-button click signal is sensed; and extracting, by the relay device, the identification information from the first alert signal and generating a second alert signal including the identification information and location information of the relay device; and transmitting, by the relay device, the second alert signal to a terminal of a security device installed in an emergency services organization or installed in a terminal or a vehicle of an emergency rescue worker by a preset dedicated wireless protocol in which a common channel of a specific frequency band assigned to transmit and receive urgent wireless signals to and from the emergency services organization is set. - View Dependent Claims (8, 9, 10)
