Description

TECHNICAL FIELD [0001] The present invention relates to a multi-seismic information processing apparatus and a multi-seismic information processing apparatus for real-

The present invention relates to an apparatus and method for processing multiple seismic information for a real-time seismic alert, and more particularly, to an apparatus and method for multi-seismic information processing for real-time seismic alert, An earthquake early warning and earthquake information from a remote system, and multiple information such as a predicted maximum ground acceleration and a predicted instrument progress information of an installation area, and issuing an alarm on a screen or a sound.

As a realistic alternative to mitigation of disasters due to earthquakes at the current technology level, where short-term predictions of earthquakes are impossible, prompt response based on earthquake early warning and rapid damage assessment is required. The earthquake early warning system uses the speed difference between the P wave and the S wave that are propagated at the same time as the earthquake to generate an alarm in the area before reaching the S wave that can cause damage and provide time for driving a predetermined response system . On the other hand, rapid response refers to the follow-up measures to recover the direct damage caused by the earthquake and to minimize the secondary damage, and it should be prioritized to assess the damage caused by the earthquake, extent and extent.

In the case of earthquakes over a certain size, the state agency announces the time, location, and scale (these are called the three elements of earthquake occurrence time, location and size) through broadcasting media, the Internet, and SNS. However, Considering the propagation speed, it can be judged that it provides a level of fact information. In other words, since it takes about 1-2 minutes to analyze and propagate the seismic element, there is a problem that it can not cope with the direct vibration due to the earthquake when the propagation speed of the seismic wave is considered.

To compensate for this, an earthquake early warning system using only P-wave information is operated to shorten the analysis time of seismic elements. An earthquake early warning was posted on the homepage of the Korea Meteorological Administration within one minute from the time of earthquake occurrence, and an earthquake breaking news was posted after one minute and an earthquake notification after four minutes was posted. In general, if an earthquake of a certain magnitude (5.0) or more is expected to cause earthquake damage, early warning of earthquake, breaking of earthquake, and finally earthquake information are announced. However, the information provided is limited to seismic elements, which are wide-area information, and do not provide sufficient information for earthquake response of individual institutions and individuals. In addition, it takes a long time to propagate to individual institutions and individuals due to limitations of information propagation media, and there is a limit that can not receive any information for a few minutes after sensing the earthquake.

On the other hand, the earthquake early warning system obtains data from the seismograph installed scattered throughout the country, selects the P wave of each observation station, analyzes it, and issues an early warning. According to the operation method of the earthquake early warning system, it takes time until seismic waves propagate to several or more stations after earthquake and P wave is selected. At the moment of early warning after analysis, . This is called the shadow zone of the early warning earthquake, which depends on the distribution and operation of the observatory and the conditions of the observation environment. In the case of the racing earthquake, the radius is calculated to be about 50 km.

In order to reduce these shadows, an earthquake early warning system using on-site alarm system is proposed. However, there is a problem that the information provision method at the national level can predict the time when information is transmitted to individual institutions and individuals, which are the subject of the earthquake response, and can not provide concrete information about the area or building necessary for actual response.

1 and 2, an apparatus for processing multiple seismic information for real-time seismic alert of the present invention includes a site data processing unit 100, a multiple seismic information processing unit 200, a control server 300, .

First, the site data processing unit 100 detects an earthquake vibration in an installed area. The field data processing unit 100 determines whether the detected earthquake vibration exceeds a threshold value, and generates a local alarm including the earthquake information. That is, the field data processing unit 100 generates the maximum ground acceleration information in a quasi-real-time and real-time using an acceleration sensor, and this information is used to generate the instrument progress information of 1 Km X 1 Km level which is more detailed than the wide- . By using this information, it is possible to provide information necessary for prompt response by individuals and individual organizations receiving earthquake-related alarms by selectively receiving data around the current installation position and producing and alarming the gauge from the maximum ground acceleration.

The multiple earthquake information processing unit 200 receives multiple earthquake information including the earthquake early warning, earthquake early warning, earthquake information, predicted maximum ground acceleration, and predictive instrument vibration information from the remote system 10 and determines the received multiple earthquake information When the threshold value is exceeded, a wide-area alarm including earthquake-multiplexed information is generated. At this time, the threshold value can be set in the range of 3 degrees to 5 degrees according to the setting, and a wide area alarm can be generated when the threshold value is exceeded.

The remote system 10 may be a weather station or other system that provides earthquake information. On the other hand, the threshold value for judging multiple earthquake information may be an intensity of 3 or more, preferably an intensity of 4 to 5 or more.

The announcement of the level-specific alarm is transmitted in a selected mode of broadcasting and unicasting. Preferably, a broadcasting scheme is used in which a message is transmitted in a different manner for each selected region.

The seismic message may indicate receipt by one vibration, and the emergency evacuation message may be configured to generate two consecutive short vibrations to recognize that it is an emergency message. In the case of a station outside the risk radius of the nuclear power plant in the S region, only an earthquake warning is issued and a corresponding message is transmitted.
