Description

{SYSTEM FOR BROADCASTING EARTHQUAKE WARNING}

An embodiment of the present invention relates to an earthquake warning broadcasting system.

An earthquake is a phenomenon in which sudden earthquake fluctuations occur in the earth, and waves (seismic waves) generated by the impact are transmitted to the earth's surface and shake the ground. The magnitude of such an earthquake ranges from a very small earthquake To large-scale earthquakes that cause damage.

An earthquake of 7.6 magnitude or more occurred in all over the world in recent 50 years, reaching about 500 times. In December 2004, a magnitude 7.6 earthquake occurred in the coast of Sumatra, Indonesia, causing an earthquake of 280,000 people. , The earthquake of 4.8 magnitude occurred in Pyeongchang on January 20, 2007 and the earthquake of 5.1 magnitude and 5.8 magnitude occurred in 9 km southwest Southwest of Gyeongju Province on September 12, 2016, .

If an earthquake occurs as described above, it will guide earthquake occurrence information at the National Emergency Management Agency, the National Disaster Safety Portal, and the National Security Agency based on information obtained from seismographs installed nationwide, universities or research institutes across the country. It is recommended that broadcasts and media be broadcasted (breaking news).

Therefore, in case of an earthquake, individuals or households can identify and respond to earthquakes through disaster letters transmitted from television, radio or internet and disaster management center. Users can check earthquake occurrence information through television, radio, The user can not confirm the occurrence of the earthquake, so that it is difficult to evacuate quickly. Furthermore, even if the user confirms the earthquake occurrence information and evacuates, he / Even if they know it, there is a problem that they are embarrassed and unable to evacuate safely or take much time to evacuate.

Therefore, in case of an earthquake, automatically obtain earthquake information from the Disaster Management Center or the Korea Meteorological Agency and automatically alert the residents to the effects of the earthquake, or obtain earthquake information from the earthquake accelerometer to evacuate residents safely and quickly. It is required to develop an automatic earthquake warning broadcasting system.

[ For this purpose, the alarm broadcast signal output unit 120 can perform a pre-set seismic warning broadcast according to the earthquake intensity or magnitude of the seismic data. In addition, the alarm broadcast signal output unit 120 may recognize the seismic data received from the first wireless transceiver unit 112 as an earthquake occurrence signal and output a collective earthquake warning broadcast signal corresponding thereto . That is, instead of outputting an alarm broadcast signal according to the magnitude and magnitude of an earthquake, it is possible to recognize only the fact of occurrence of an earthquake and to carry out consistent alarm broadcast accordingly.

The alarm broadcasting signal transmitting unit 130 may be installed in a management center 20 for managing a plurality of buildings 10 and may receive earthquake data from the earthquake sensing unit 110 and wirelessly receive earthquake data The alarm broadcast signal output unit 120 can transmit an alarm broadcast signal set in advance.

In addition, a temperature-compensated crystal oscillator (TCXO) may be applied to enhance the temperature characteristic of the second wireless transceiver unit 131 at an operating temperature of -20 ° C to 85 ° C. Also, the communication speed (radio portion) of the second wireless transmitting / receiving unit 131 can be changed, and a universal asynchronous receiver / transmitter (UART) can be applied and the communication speed is 4800 BPS / 9600 BPS / 19200 BPS Is 19200 BPS). Also, the second wireless transceiver 131 can operate in the relay mode, and the relay mode can relay in seven stages. Also, the second wireless transmission / reception unit 131 can install 37 channels in the 2 MHz band.

When the earthquake data is received from the first wireless transmitting / receiving unit 112 through the second wireless transceiver unit 131, the alarm broadcasting apparatus unit 132 detects the magnitude of the earthquake based on the voltage level information of the received earthquake data The scale can be judged. In addition, the alarm broadcasting unit 132 can transmit an alarm broadcasting signal to the alarm broadcasting signal output unit 120 according to the magnitude and magnitude of the determined earthquake. In this case, the alarm broadcasting unit 132 may be connected to the alarm broadcasting signal output unit 120 through wired communication using a communication line, as shown in FIG. 2, to transmit the alarm broadcasting signal.

The manual broadcast transmitting unit 132a is a means for manually transmitting an alarm broadcasting signal using the upbringing of an administrator. The manager of the managing center 20 uses a microphone (not shown) So that the alarm broadcast signal can be sent to each building 10 manually.

The automatic broadcasting transmitting unit 132b can automatically transmit an alarm broadcasting signal set in advance according to the seismic data. More specifically, different or some similar alarm broadcasts recorded in advance according to the magnitude and magnitude of the earthquake summarized in Table 1 below can be automatically transmitted. Alarm broadcasts may include various information such as the status report according to the magnitude and magnitude of the earthquake and the evacuation tips and countermeasures accordingly.
