The present invention relates to a method and system for automatic emergency notification.

In the event of an accident on the road, in general, when the accident party or witness informs the relevant organizations of the accident and the location of the accident, such as a police station, a hospital, or a fire department, the relevant agency accompanies a rescue vehicle to the accident location. Dispatch the apprentice. However, when the accident is severe or there are no witnesses, it is delayed to inform the authorities about the accident and the location of the accident. As a result, the parties involved in the accident may be severely affected by delays in notification. In order to solve this problem, a method of detecting an occurrence of an accident and automatically notifying a related position of the accident through a mobile communication network has been sought. As an example of such a scheme, Korean Patent Registration No. 0171496 and Korean Patent Application Publication No. 2001-0049792 are disclosed. Republic of Korea Patent No. 0171496 (hereinafter referred to as the first conventional technology) relates to a device for transmitting and receiving rescue signals for automobiles and will be described schematically with reference to Figure 1, Republic of Korea Patent Publication No. 2001-0049792 (hereinafter, referred to as the second conventional) Technology) relates to a method for providing a location tracking service for an accident vehicle equipped with a sensor, and will be described with reference to FIG. 2.

1 is a block diagram of an apparatus for transmitting and receiving a rescue signal generated in a vehicle according to the first prior art.

Referring to FIG. 1, the distress signal transceiving device includes a shock sensor 105, a controller 101, a transmitter 103, a keyset switch 107, a frequency generator 109, and an antenna 111. The shock sensor 105 detects a shock due to an accident and generates a shock detection signal. The controller 101 generates a control signal based on the shock detection signal received from the shock sensor 105. The transmitter 103 and the frequency generator 109 oscillate a radio frequency in order to wirelessly transmit the control signal generated by the controller 101. The oscillated radio frequency is transmitted to the outside through the antenna 111. Looking at the operation of the structure signal transmission and reception device having the configuration as described above are as follows.

When an accident occurs while driving a vehicle, the shock sensor 105 generates a shock detection signal by detecting a shock and outputs it to the controller 101. The controller 101 generates a control signal based on the input shock detection signal and outputs the control signal to the transmitter 103. The control signal is oscillated at a radio frequency by the transmitter 103 and the frequency generator 109 and is transmitted through the antenna 111. The transmitted radio frequency is received by the receiving antenna and the receiver of another vehicle operating in a position close to the accident position and output to the position indicator. The occupant of another vehicle may take emergency measures by easily determining the accident location based on the radio frequency output to the location indicator.

The sensor 201 generates a shock detection signal by detecting a shock according to an accident and outputs the shock detection signal to the control device 203. The control device 203 detects the shock level based on the shock detection signal and notifies the service provider 209 through the short message service using the mobile communication terminal 205. The service provider 209 notified of the accident requests the wireless location center 207 to confirm the location of the vehicle.
