Description

Early earthquake early warning system and early warning method

Technical Field

The invention relates to a communication technology, in particular to a communication technology related to earthquake alarming.

Background

With the improvement of human civilization and the development and progress of scientific technology, the influence of many natural disasters on human beings is greatly controlled. However, since the occurrence of natural phenomena such as the vendang earthquake cannot be predicted completely and accurately, it is urgent and necessary to establish an early earthquake early warning system which facilitates the warning of general residents in an earthquake area to win as much escape time as possible in a timely manner so as to minimize the loss and casualties caused by the earthquake.

Japan has the most advanced earthquake early warning system in the world. In 10.2007, japan has just developed an earthquake early warning system for warning an earthquake by multimedia. In this system, an earthquake warning is transmitted to residents in a seismic area through, for example, a network or a television, thereby achieving the purpose of issuing an earthquake warning on a large scale. However, people who are not near the television or computer still cannot be warned of the earthquake in a timely manner.

Drawings

The various aspects of the present invention will become more apparent to the reader after reading the detailed description of the invention with reference to the attached drawings. Wherein,

fig. 1 shows a block diagram of the construction of an early seismic early warning system according to the present invention.

Detailed Description

Embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

Fig. 1 shows a block diagram of an early seismic warning system of the present invention. The following description will be made in the case where the system includes a plurality of seismic sensing units, an arbitration unit, a mobile communication server, and an alarm issuing unit. But not limited to only one arbitration unit, one mobile communication server and one alert issuing unit. In the present embodiment, the dangerous seismic signal is transmitted by GSM, but it should be understood by those skilled in the art that the present invention is not limited to GSM, but may be implemented by other methods such as ETSI, 3G communication technology. For a detailed description of GSM, ETSI, and 3G technologies, reference may be made to the relevant communication protocol standards, and these technical documents are incorporated herein by reference in their entirety and fall within the scope of the present invention.

As shown in fig. 1, the early earthquake early warning system includes: anearthquake detection unit 101, anarbitration unit 102, amobile communication server 103, and analarm issuing unit 104. Each of which is described in detail below.

Theseismic acquisition unit 101 includes at least one P-wave sensor and a raw seismic signal transmitter. In general, when an earthquake starts, the earthquake starts with a shorter wavelength, i.e., P-wave. The earthquake at this time generally cannot cause damage, and the human body cannot feel the vibration. After a few seconds, the S-wave vibration starts. The S-wave vibration has a longer wavelength, and the damage caused by the vibration is also large, such as the collapse of a building. And the seconds are enough to make the escape possible for the residents in the earthquake area.

Based on this principle, it is first necessary to arrange as many P-wave sensors as possible in the area to be detected. The more P-wave sensors, the more raw seismic signals are returned. More or less original seismic signals directly affect the accuracy and precision of prediction of epicenter position and seismic intensity.

After the P-wave sensor detects the raw seismic signal, the detected raw seismic signal is sent to thearbitration unit 102 by a raw signal transmitter within theseismic detection unit 101.

Thearbitration unit 102 is provided therein with an original seismic signal receiver, an arbitrator, and a dangerous seismic signal transmitter. Wherein the original seismic signal receiver is used for receiving the seismic signal emitted by the seismic detection unit (101) and transmitting the original seismic signal to the arbitrator.

The resolver first needs to receive a large number of different raw seismic signals. These seismic signals may be fromseismic detection units 101 disposed at many different locations. Based on these seismic signals, the resolver further processes the analysis and then makes a determination as to which of the original seismic signals are predictive of a future destructive earthquake and which of the original seismic signals are indicative of a non-destructive earthquake.

When the resolver decides that there is a destructive earthquake, thearbitration unit 102 immediately transmits a dangerous seismic signal to themobile communication server 103 through a dangerous seismic signal transmitter.

After receiving the dangerous earthquake signal, themobile communication server 103 transmits the signal to each base station in the earthquake area through the GSM communication protocol, and then the base station transmits the dangerous earthquake signal to all thewarning emission units 104 located in the coverage area.

The communication method between thearbitration unit 102 and theseismic detection unit 101, and between thearbitration unit 102 and themobile communication server 103 may be wireless or wired.

The warning issuingunit 104 may take various forms.

First, the warning issuing unit may be a mobile phone. At this time, the mobile phone first needs to activate a Cell Broadcast (CB), also called short message service-cell broadcast (SMS-CB) function. Cell broadcast is a one-to-many geographically focused information service designed to simultaneously transmit information to multiple users in a particular area. CB is a mobile feature defined by the GSM committee of ETSI and is part of the GSM standard. Cell broadcast information is also generally supported by UMTS, and is also defined by 3 GPP. After the cell broadcasting function is turned on, the mobile phone can receive dangerous earthquake signals sent by the base station. The user of the mobile phone can take refuge measures in time after receiving the warning message. Of course, the base station may also notify the user of the mobile phone by means of a voice call to thereby issue a warning.

Secondly, the warning sending unit can also be other light-emitting and sound-producing devices such as an air defense alarm, a siren, a loudspeaker, a warning lamp and the like which are integrated with a receiving module of the mobile communication terminal. This type of warning issuing unit can be located in a building, on a square, or in other ways flexibly in crowded areas. The alarm issuing unit, upon receiving a dangerous seismic signal from a base station through a mobile communication receiving module embedded therein, immediately issues an alarm to a crowd located near the alarm issuing unit by sounding an air defense alarm, whistling, or other means. The warning unit further comprises a power plug and a spare battery.

Hereinbefore, specific embodiments of the present invention are described with reference to the drawings. However, those skilled in the art will appreciate that various modifications and substitutions can be made to the specific steps and types of instant messaging messages in the specific embodiments of the present invention without departing from the spirit and scope of the present invention. Such modifications and substitutions are intended to be included within the scope of the present invention as defined by the appended claims.
