The present invention relates to a disaster alert method and apparatus, and a disaster alert system using the same. In particular, the present invention relates to a disaster alert system in a simple manner by broadcasting a preset disaster alert message in response to a disaster alert signal including a disaster code. The present invention relates to a disaster alert method and apparatus, and a disaster alert system using the same.

Natural disasters such as typhoons, floods, torrential rains, storms, tsunamis, heavy snowfall, earthquakes, tsunamis, landslides, fires, collapses, explosions, forest fires, NBC accidents, and environmental pollution accidents are impossible to completely prevent. However, damages can be minimized if R & D and effective disaster prevention procedures for disaster prevention, emergency measures and recovery are established in advance.

As economic and cultural levels improve, efforts are being made to prevent and prevent disasters and disasters, and research and development of related technologies are being actively conducted. However, due to changes in global weather and social structure, disasters and disasters are becoming more diversified, and the scale of damage is also increasing. Accordingly, a faster and more effective disaster prevention system is urgently needed.

The current disaster prevention system is mainly a disaster warning system operated by disaster prevention departments or flood control centers of central or local governments. The procedures for operating such a disaster alert system are as follows.

There are a variety of disaster factor stations that look at the causes of disasters and disasters. Weather stations monitor weather factors such as temperature, rainfall, humidity, and wind speed, while hydrological stations use river levels, rainfall, and tides. Earthquake stations and forest fire stations monitor earthquakes and wildfire-related disasters.

The disaster alert system collects and analyzes the observed data from various disaster factor stations, and uses the results to determine the likelihood and extent of disasters. And if it is necessary to alert, etc., the disaster alert system announces it through the media such as newspapers and broadcasting.

However, in case of a disaster that requires rapid evacuation such as flood, tsunami, or earthquake, such a general disaster warning system cannot use the media such as broadcasting to obtain a practical warning effect considering the urgent need of the matter. There is a problem inevitably enormous damage to people and property damage. That is, such a general disaster alert system takes a long time to issue an alarm for an area where an emergency disaster or disaster occurs or is predicted, and thus does not function properly as a preventive system.

With the development of mobile communication technology, a number of methods using a mobile communication terminal have been proposed to solve this problem. The method using a mobile communication terminal generally utilizes a short message service. Representatively, there is a method of transmitting a disaster alert through a short message service by using a mobile communication terminal as part of a disaster alert system.

However, there are many cases where the user cannot check the short message information in certain situations such as when the user vibrates the terminal or when the terminal is turned off, and the user does not immediately check the message information. Therefore, the method of using the short message service of the mobile communication terminal also has a problem that does not properly serve as a precautionary system.

Patent Publication No. 2003-84859 discloses disaster information collected and analyzed by an operator computer and a disaster factor station, and when a disaster or disaster is predicted, a short message service provides an emergency situation to a wireless terminal in a disaster or disaster prediction area. A method of transmitting is disclosed. As a method of transmitting to a wireless terminal, a broadcast type SMS method, which is one of general message transmission formats, or a method of transmitting an emergency situation in a 1: 1 transmission format using mobile communication switching network information of a corresponding region.

However, this method is a method of automatically notifying the alarm situation through the mobile communication text information using a general mobile communication wireless terminal, the user has a problem that does not recognize the message reception in the commonly used wireless mobile terminal as it is However, some users may not be able to recognize the emergency situation in case of a disaster and may not be able to receive it.

On the other hand, the broadcast SMS method is made to be used for general purposes, such as transmitting news by text in mobile communication, in order to use this as an emergency alert to apply a separate transmission format for the alert is used for general purposes. It should be possible to prevent the user from confusion by using a separate case, but since the transmission format is not distinguished, there is a problem that the user is recognized as a daily message reception even when using the broadcast type SMS method.

As such, the conventional methods have already been utilized for disaster prediction for a long time, or used mobile terminals to quickly and accurately communicate the situation of disaster occurrence to everyone, but the general terminal disaster without the addition of a function for alarm processing As it is applied to an alarm system, it has a fundamental problem in accordance with general terminal use habits. Therefore, there is a need to build an alarm system capable of overcoming the fundamental problems caused by the user's usage habits and to effectively alert each user.

The technical problem to be achieved by the present invention is to broadcast a disaster notification message which is set in advance in response to a disaster notification signal including a disaster code, a method and apparatus for a disaster alert in a simple manner even in a standby state, and a disaster alert using the same To provide a system.
