s4) performing earthquake early warning for the main administrative area.

In the embodiment of the invention, the earthquake early warning receiving end is a device for early warning a user, and the device can have the functions of data calculation and instruction processing and can also have the function of outputting acousto-optic signals and the like for early warning and warning information. The seismic warning receiving end may have a processor and a memory having stored thereon instructions executable by the processor to implement the foregoing method when executed by the processor. The multi-target earthquake early warning method can be executed by an earthquake early warning receiving end, or the multi-target earthquake early warning method can also be applied to an earthquake early warning center. In some exemplary applications, the server of the earthquake early warning center performs steps S2) to S3), the earthquake early warning center may transmit the identifier obtained by the screening to the earthquake early warning receiver, in which case, step S4 may be performed by the earthquake early warning receiver), and the earthquake early warning receiver may not need to perform steps S1) to S3), so that flexibility is provided.

In some embodiments, the earthquake early warning receiving end may include a mobile device such as a mobile phone and a tablet computer, a personal computer, a television, a server, and the like, which are installed with an application program, and may also include a device for special early warning broadcast, a control device, and the like. The earthquake early warning receiving end provides information for users. The earthquake early warning receiving end can broadcast the early warning information at least in a picture or audio frequency mode.

In some main application scenarios, the earthquake early warning receiving end may provide required information to users such as emergency management departments and other related departments at the location of the earthquake early warning receiving end, or enterprises with requirements, for example, the earthquake early warning receiving end may include a server, the server may be connected to a central control screen to present an operating state in real time, meanwhile, the earthquake early warning receiving end may also include a mobile phone, the mobile phone is installed with an application program, the application program may perform data synchronization (web page or other message application programs) with the server through a designated interface, or the application program may have a function of implementing the foregoing method when being executed by a processor, so as to implement real-time pushing to related platforms or personnel at each department.

In the embodiment of the present invention, in step S1), the basic parameters (or called seismic information) of the seismic early warning may include: the earthquake-starting time, the earthquake-center position (including longitude and latitude information), the early warning earthquake magnitude and the like. It is understood that an administrative area is an area with certain latitude and longitude information.

In the embodiment of the invention, when an earthquake occurs, the earthquake early warning receiving end can measure the influence of the earthquake on each administrative area by combining the numerical value of the earthquake early warning basic parameter and the longitude and latitude information of the administrative area, and screen and early warn the administrative area; or the server of the earthquake early warning center measures the influence of the earthquake on each administrative area by combining the numerical value of the earthquake early warning basic parameter and the longitude and latitude information of the administrative area, the identifiers of the main administrative area are sent to an earthquake early warning receiving terminal after screening, and the earthquake early warning receiving terminal carries out early warning on the main administrative area. In view of this, the server and the earthquake early warning receiving terminal of the earthquake early warning center can be used to jointly complete the early warning, and when the multi-target earthquake early warning method is applied to the server and the earthquake early warning receiving terminal of the earthquake early warning center, the method specifically includes:

executing, by a server of a seismic early warning center: screening identifiers of administrative areas based on the earthquake early warning basic parameters;

executing, by a server of a seismic early warning center: determining a main administrative region corresponding to the identifier obtained by screening and/or the designated identifier;

executing by an earthquake early warning receiving end: receiving an identifier set or list of the main administrative areas and early warning information of each administrative area in the main administrative areas, which are issued by an earthquake early warning center;

executing by an earthquake early warning receiving end: performing earthquake early warning for the main administrative area;

at this time, the earthquake early warning receiving end may not perform the step S2) and the step S3) for screening and determining, respectively.

Further, step S2) may include:

s2001) measuring the influence degree of an administrative region based on the earthquake early warning basic parameters;

s2002) screening the identifier of the administrative area based on the degree of influence.

The degree of influence may include, among other things, a degree of influence and/or a range of influenced values and/or an influenced value. The identifier of the administrative area may include any of the name of the administrative area (e.g., Changning county, Sichuan, Changning or Changning, Sichuan), a single word abbreviation (e.g., Sichuan, Changning), a serial number or code (e.g., Kangdu Gaoxin district, 510102), a numeric code (e.g., Sichuan, 51), and an arbitrarily-designated unique string. The data of each administrative region may be formed based on the identifier by a table and/or a database, etc., so as to record relevant information about the administrative region affected by the earthquake, which can be understood in the embodiment of the present invention.

In some embodiments of the present disclosure, the degree of influence may be measured numerically, and step S2001) may include:

based on the earthquake early warning basic parameters, calculating early warning metric values of the administrative region by combining a longitude and latitude database of the administrative region, wherein the early warning metric values comprise at least one of the following values: the epicenter distance, the early warning time and the pre-estimated intensity.

Specifically, at least one of the following may be included:

s2101) determining the longitude and latitude of a designated point corresponding to the identifier of the current administrative area from the longitude and latitude database of the administrative area, and calculating the epicenter distance corresponding to the identifier of the current administrative area according to the longitude and latitude of the designated point and the longitude and latitude of the epicenter position;

s2102) calculating early warning time corresponding to the identifier of the current administrative area according to the epicenter distance and the earthquake starting time;

s2103) calculating the estimated intensity corresponding to the identifier of the current administrative area according to the earthquake early warning basic parameter early warning earthquake magnitude and the earthquake center distance. The estimated intensity represents an estimated damage degree caused when destructive seismic waves of an earthquake are transmitted to the current administrative area.

In the embodiment of the present invention, the epicenter position may be a monitored position point, and the position point may be a point located by latitude and longitude information. The identifier of the current administrative area represents an identifier of a certain administrative area on which the calculation is being performed, instead of an identifier of the administrative area at the location of the seismic warning receiving end. In an example, the longitude and latitude information of the boundary of the current administrative area may be determined from the longitude and latitude database of the administrative area, and a plurality of location points on the boundary may be taken as a plurality of designated points, where the calculated epicenter distance may be a numerical range, for example, the closest distance and the farthest distance from the plurality of designated points in the current administrative area to the epicenter position form a distance numerical range, i.e., the epicenter distance; in another example, a typical location point in the current administrative area can be determined from the longitude and latitude database of the administrative area, and the location point is used as a designated point, such as a landmark building location point in an urban administrative area, a special production location point needing special attention, and the like.

It should be noted that the selection of the aforementioned designated points is only used as an example, not a limited and unique implementation, and can be adjusted and changed according to the test or the use effect. The aforementioned administrative area longitude and latitude database may be configured in the earthquake early warning receiving terminal, or the aforementioned administrative area longitude and latitude database may be configured in a server of the earthquake early warning center and may be queried by the earthquake early warning receiving terminal. The database prestores the place name, the administrative grade and the latitude and longitude information. For example, the database may include longitude and latitude information records such as an identifier of a district a, longitude and latitude (north latitude NA °, east longitude EA °) and a longitude and latitude boundary array 1, an identifier of a county b, longitude and latitude (north latitude NB °, east longitude EB °) and a longitude and latitude boundary array 2, an identifier of city c, longitude and latitude (north latitude NC °, east longitude EC °) and a longitude and latitude boundary array 3, and may also be specifically recorded as an identifier of a district e in city d, longitude and latitude (north latitude ND °, east longitude ED °) and a longitude and latitude boundary array 4, where NA-ND and EA-ED both refer to numbers. Each latitude and longitude boundary array may be a column of latitude and longitude values, respectively. The region granularity can be one or more of provincial level, city level, county level/partition level, town level, village level, street level and the like, and can be adjusted, increased, decreased or designated position points according to specific requirements, test and use effects.

The early warning time, namely the earthquake early warning time, is the time when destructive earthquake waves reach an earthquake early warning receiving end or an area where a user is located. The early warning time can be calculated by using the destructive seismic wave velocity in combination with the origin time and the epicenter distance, wherein the velocity can be the seismic wave shear wave velocity.

This early warning time is very important for users to take earthquake risk avoidance strategies and emergency measures, for example, the early warning time for Changning earthquake survival is 61 seconds, and users can take emergency risk avoidance or evacuate by using the time.

After the degree of influence is measured, a screen may be performed. In some embodiments of the present disclosure, the server or the earthquake early warning receiver of the earthquake early warning center may have one or more optional screening (working) modes. Various optional screening modes can be simultaneously started in a server or an earthquake early warning receiving end of the earthquake early warning center, and various screening modes can be executed according to a configuration mode and a sequence, namely, other screening modes can be started on the basis of starting some screening modes. Alternatively, an enabled screening mode may be selected, which obtains the identifier of the administrative area not understood as one identifier, but as the entire identifier derived from one screening mode. It will be appreciated that it is also possible to directly enable only one screening mode. The specifically enabled screening mode may be adapted to the characteristics of each region based on test and historical data, enabling the appropriate screening mode.

In the first screening mode, step S2002) may include:

ranking identifiers for the administrative regions based on the early warning metric values. Specifically, the method may include:

s2201) sequentially determining the arrangement serial numbers of the identifiers of the administrative regions according to the size arrangement mode of the epicenter distances; or

S2202) sequentially determining the arrangement serial numbers of the identifiers of the administrative regions according to the arrangement mode of the early warning time; or

S2203) sequentially determining the arrangement serial numbers of the identifiers of the administrative regions according to the arrangement mode of the pre-estimated intensity.

In the first filtering mode, identifiers of each administrative region may be arranged from small to large using the numerical value of the closest distance in each epicenter distance (i.e., the arrangement number of the identifiers arranged in the front may be a relatively small number, and the numerical value of the corresponding closest distance is also relatively small); similarly, the identifiers of the various administrative regions can be arranged from small to large and from large to small, respectively, using the values of the warning time (values small before) and the predicted intensity (values large before). The results of arranging by adopting the early warning time or the estimated intensity are basically not different from the results of arranging by adopting the epicenter distance, and the calculation process and the arrangement basis are different because the different early warning measurement values have associated change relations, namely, the smaller the epicenter distance is, the shorter the early warning time is, the larger the estimated intensity is, therefore, if one type of early warning measurement value is used, the other types of early warning measurement values can not be calculated, so that the time is saved. For example, for arranged data processing, the precaution metric values of the respective administration areas (i.e., precaution metric values corresponding to identifiers of the respective administration areas) may be placed in a table or set for caching, and then the arrangement may be performed.

In addition, in some exemplary few applications, steps S2201) to S2203) may all be used, for example, the epicenter distance, the early warning time and the predicted intensity are normalized and weighted and summed, and the identifiers of the administrative regions are arranged by using the weighted and summed values. Therefore, at least one of the steps S2201) to S2203) may be performed.

In this first screening mode, after alignment, screening can be completed. The aforementioned step S2002) may further include any one of:

s2204) selecting at least N identifiers from the arranged identifiers, wherein the arrangement numbers of the selected at least N identifiers belong to a configured numerical range, and N is a positive integer;

s2205) selecting at least K identifiers from the arranged identifiers, wherein K is a positive integer and the value of K is in positive correlation with the early warning magnitude in the earthquake early warning basic parameters;

s2206) selecting an affected administrative region whose pre-warning metric value reaches a pre-warning metric threshold.

In step S2204), N identifiers with smaller (top) rank numbers are screened. In an exemplary embodiment of the disclosure, N may be 4, and when 4 identifiers are selected, information of corresponding 4 administrative areas will be highlighted and collectively presented on an interface at a receiving end of the earthquake early warning, which will greatly contribute to the orderliness and identifiability of the interface information.

In step S2205), K identifiers with smaller rank numbers are screened. The value of K matched with the early warning magnitude can be specified by the positive correlation, and the method is particularly beneficial to early warning of the affected area in time when an earthquake with serious influence occurs.

When any one of the early warning metric values in the step S2206) reaches the early warning metric threshold, the identifier of the administrative region corresponding to the any one of the early warning metric values may be obtained by screening, for example, the estimated intensity is greater than the estimated intensity threshold, or the early warning time is less than the early warning time threshold, or the epicenter distance is less than the epicenter distance threshold.

In some applications, one or two or three of steps S2204) to S2206) may be performed, and when two or more of the steps are performed, the union of the identifiers obtained in the respective steps may be used as the identifier (set) obtained by the filtering. That is, at least one of the administrative areas corresponding to the at least N identifiers, the administrative areas corresponding to the at least K identifiers, and the affected administrative areas is set as a main administrative area. The main administrative region and database records such as longitude and latitude information of the main administrative region can be determined through a lookup table/database according to the identifier set obtained by screening. Wherein, at this time, the primary administration may be a set/list of measured administrations that will be affected by the earthquake. The administrative areas in these sets/lists of administrative areas that will have obvious senses of earthquakes (and will have slight senses of earthquakes) may be obtained by the specific processing of the foregoing steps S2) to S3), and are taken as a plurality of targets to be pre-warned. It should be noted that the main administrative area is not only obtained in the first screening mode, but may be obtained in the following screening modes.

In the second screening mode, the degree of influence may be measured in a numerical range, and step S2) may include:

s2211) determining the circle center based on the longitude and latitude information of the epicenter position in the earthquake early warning basic parameters;

s2212) forming an estimated influence range by taking the epicenter distance threshold as a radius;

s2213) obtaining the identifier of the administrative region within the estimated influence range; wherein the content of the first and second substances,

In the mode, the earthquake early warning receiving end takes the earthquake center position as the center of a circle, the earthquake center distance threshold value can be used as the radius, for example, 300km to 500km is used as the radius, and the radius can be determined according to the early warning magnitude, wherein the higher the early warning magnitude is, the longer the radius is; in some illustrative examples, according to the positive correlation, the epicenter threshold and the early warning magnitude value table can be formed by combining the characteristics of each administrative region during testing and use, and the epicenter threshold is generated adaptively based on the table. Then, the identifiers of all administrative areas within the predicted influence range are obtained.

In this second screening mode, for some exemplary applications, step S2) may further include:

s2214) judging whether the number of administrative areas within the estimated influence area range exceeds an area number threshold value or not;

s2215) if the number of the administrative areas is not exceeded, acquiring identifiers of administrative areas within the predicted influence area range;

s2216) if yes, shortening the radius of the estimated influence area, and performing S2217);

s2217) determining whether the number of administrative regions within the predicted influence region range after the radius is shortened exceeds the region number threshold, if not, obtaining the identifier of the administrative region within the predicted influence region range after the radius is shortened, and if still, returning to step S2216. The number threshold of the regions may be 4.

In some examples, the size of each shortening radius may be taken to be 20km, 30km, etc. In this mode, the main administrative areas can be obtained by screening without calculating all the administrative areas. The public values such as the area number threshold value and the radius shortening value each time are not limited numerical values, and can be set according to the actual use and test effects, for example, the area number threshold value and the early warning magnitude can have a positive correlation numerical value matching relationship, the radius shortening value each time can be set based on the total number of administrative areas, and the like.

The first screening mode and the second screening mode are matched, and the influence degree can be measured in a numerical range and a numerical value. In some exemplary embodiments, may include:

A1) obtaining identifiers of a plurality of administrative areas within the predicted influence range in the second screening mode;

A2) calculating early warning measurement values of the administrative areas;

A3) the identifiers of the administrative areas are specifically arranged in a first screening mode based on the early warning metric.

Wherein, a and S both represent step marks. In some exemplary embodiments, the earthquake early warning receiving end draws a circle with the epicenter position as a center and 300km-500km as a radius (specifically, the radius is longer as the early warning magnitude is determined according to the early warning magnitude), obtains the longitude and latitude of all cities, counties and/or regions in the circle, calculates the epicenter distances (distances from the epicenter positions) of all cities, counties and/or regions in the circle, and arranges all cities, counties and/or regions in the circle from short to long according to the epicenter distances, so that the system operation speed can be improved.

The identifiers of a plurality of administrative areas are obtained by using the second screening mode, the early warning measurement values of the identifiers are calculated, and then the identifiers of the administrative areas are screened by using the first screening mode, so that the early warning measurement values of all the administrative areas can be prevented from being calculated in a traversing mode, and the calculation time of the administrative areas which are not affected by the earthquake and have no or almost no earthquake is shortened.

In the third filtering mode, step S2) may include:

s2221) positioning and identifying a provincial administrative region of the epicenter position based on longitude and latitude information of the epicenter position in the earthquake early warning basic parameters;

s2222) calculating the closest distance between the provincial administrative area and the epicenter position based on the boundary longitude and latitude information of the provincial administrative area and the longitude and latitude information of the epicenter position;

s2223) determining that the closest distance exceeds a epicenter distance threshold, and obtaining an identifier of the provincial administrative region.

The longitude and latitude information of the boundary of the provincial administrative region can be used for calculation according to the specified point mode; the location points of provincial administration in the geographic cardinal directions, such as those in the east, north, south, etc., may also be used, and the closest distance between these location points and the epicenter location may be calculated. In step S2223), the epicenter distance threshold (which may be a numerical range) and the early warning magnitude are also in a positive correlation and have a corresponding numerical match, and the epicenter distance threshold may be set to 300km to 500 km. And if the fact that the distance between the provincial administrative region boundary and the epicenter position is closest to the epicenter position is larger than the epicenter distance threshold value is recognized, removing data of other provinces, and only keeping the identifier of the provincial administrative region.

In the third screening mode, step S2) may further include:

s2224) determining that the closest distance does not exceed a configured epicenter distance threshold, and obtaining an identifier of the provincial administrative region;

s2225) adding identifiers and longitude and latitude information of administrative areas within the remaining provincial administrative areas, wherein the administrative areas within the remaining provincial administrative areas are within a range determined by the epicenter position and the epicenter distance threshold.

Wherein the rest provincial administration areas may be administration areas adjacent to the provincial administration area. For the judgment of the epicenter distance threshold in the third screening mode, compared with the arrangement of the first screening mode, the calculation speed can be improved, and the longitude and latitude information of all administrative areas does not need to be calculated. In the third screening mode, whether the earthquake mainly affects the current provincial administrative region or not is determined, whether other adjacent provincial administrative regions are also used as the main administrative regions or not is determined, the reasonability of the adopted emergency measures and the allocated resources is improved, and the rescue force and the rescue goods and materials can be effectively organized and coordinated.

On the basis of the various screening modes, user-defined screening modes can be added. The user can set a concerned place in the earthquake early warning receiving end, such as an area or a city where earthquakes occur frequently, a place where important facilities such as a potential earthquake-influenced major hazard source and the like are located, and the like. The place set by the user to be concerned can be a specific longitude and latitude point, or can be a city, a county or a part of a region in the region, such as the Channing county in Yibin City, and the specified identifier can be the name of the county-level region, namely the Channing county, and the identifier obtained by screening can jointly determine a main administrative region. In some application scenarios, the identifier obtained by the filtering may be empty, and at this time, there is also an administrative area corresponding to the designated identifier, which may be used as the current main administrative area. Therefore, in the embodiment of the present invention, the main administrative area may further include an administrative area and/or a location point that the user needs to pay close attention to, and the administrative area and/or the location point may be a local location of the earthquake early warning receiving end device, or a location where an emergency management department is located, or an area/a location point that the user is interested in.

Before executing the early warning, in one example disclosed in the present invention, when an earthquake occurs, a plurality of earthquake monitoring terminals (e.g. stations) near the epicenter monitor the earthquake waves and form monitoring data to be sent to a server of an earthquake early warning center, the server of the earthquake early warning center calculates to obtain earthquake information and sends the earthquake information to each earthquake early warning receiving terminal of a user position, and each earthquake early warning receiving terminal combines a longitude and latitude database of an administrative area and the earthquake information to calculate to obtain the earthquake early warning information, so that the (earthquake) early warning information can be determined.

It should be noted that the main administrative areas in the present embodiment include the administrative area where the epicenter is located and other affected administrative areas. The warning information in the present embodiment is also obtained based on the basic parameters of the earthquake warning, and may be obtained after the determination of the main administrative area and before the execution of the earthquake warning. The warning information may include an identifier of an administrative region where the epicenter location is located (e.g., a county or the same level), a seismic time, the epicenter location, a warning earthquake level, identifiers of other administrative regions in the main administrative region, predicted intensity (or earthquake influence degree), warning time, earthquake distance, and the like.

For step S4), there may also be multiple warning modes, various selectable warning modes may be enabled in the server or the earthquake warning receiving end of the earthquake warning center at the same time, and multiple warning modes may be executed in a configuration manner and in sequence, that is, on the basis of enabling some warning modes, another warning mode may be enabled. It will be appreciated that only one alert mode may be enabled. The specifically enabled early warning mode can adapt to the characteristics of each region and the characteristics of the user based on test and historical data, and the appropriate early warning mode is enabled. In the embodiment of the present invention, the screening mode and the warning mode may be both operation modes of the device.

In the first warning mode, step S4) may include:

s4401) determining that the main administrative region corresponding to the designated identifier does not belong to the main administrative region corresponding to the identifier obtained through screening, and presenting early warning information of the identifier obtained through screening and the main administrative region corresponding to the designated identifier; alternatively, the first and second electrodes may be,

s4402) determining that the main administrative region corresponding to the designated identifier belongs to the main administrative region corresponding to the identifier obtained through screening, combining the designated identifier and the identifier obtained through screening, and presenting early warning information of the main administrative region corresponding to the combined identifier.

Wherein the merging may be to take the union of the assigned identifier (set) and the identifier (set) obtained by the screening. The user can set a plurality of concerned places, and when an earthquake occurs, the earthquake early warning receiving end can additionally display the early warning information of the areas/places which the user needs to pay attention to except for a plurality of administrative areas which are closest to the position of the earthquake center according to the earthquake center distance. In some applications, if the user includes a plurality of interested areas/location points, the plurality of interested areas/location points are arranged according to the epicenter distance from short to long and the corresponding early warning information is presented.

In the second warning mode, step S4) may include: and executing voice broadcasting and/or presenting an early warning picture based on the determined early warning information of the main administrative area. And in the presented early warning picture, the early warning information of the main administrative area is presented at the same time. The early warning method can be determined according to specific hardware of an earthquake early warning receiving end, and is an early warning method of voice broadcast and/or picture countdown. Aiming at an earthquake early warning receiving end with a screen and a loudspeaker (the loudspeaker of the equipment or an external loudspeaker), voice broadcasting and picture presentation can be carried out simultaneously; aiming at an earthquake early warning receiving end with only a screen and no loudspeaker, the early warning information can be released only through picture presentation; for the earthquake early warning receiving end only provided with the loudspeaker, the early warning information can be issued only through voice broadcasting, for example, the broadcasted characters can be 'an earthquake occurs nearby a place'.

The voice broadcast may include:

broadcasting the earthquake early warning basic parameters and/or broadcasting early warning information of one of the most valuable early warning metric values in the main administrative area; or broadcasting the earthquake early warning basic parameters, and/or broadcasting the early warning information of each administrative region in the main administrative regions according to the sequence of identifiers or the numerical value of early warning measurement values.

Specifically, the voice broadcast may include:

s4411) broadcasting the earthquake early warning basic parameters and/or broadcasting early warning information of one of the main administrative area, the maximum earthquake distance (or early warning time) value and the minimum estimated intensity value (namely the administrative area); or

S4412) broadcasting the earthquake early warning basic parameters and/or broadcasting early warning information of one of the main administrative regions with the minimum earthquake distance (or early warning time) value or the maximum estimated intensity value (namely the administrative region); or

S4413) broadcasting the earthquake early warning basic parameters and/or broadcasting the early warning information of each administrative area in the main administrative areas according to the sequence of identifiers; the identifier sequence may be the identifier sequence formed by the above sequence numbers, or the identifier sequence formed by using the epicenter distance or the early warning time or the estimated intensity at this time.

In this second warning mode, in some exemplary embodiments, step S4) may further include:

s4414) determining that the early warning time difference value between administrative areas corresponding to adjacent identifiers in the arranged identifiers is smaller than the early warning time difference value threshold value, and only broadcasting the early warning information of the administrative areas with short early warning time; or

S4415) determining that the early warning time difference value between administrative areas corresponding to adjacent identifiers in the arranged identifiers is smaller than the early warning time difference value threshold value, and only broadcasting the early warning information of the administrative areas with long early warning time. Wherein, in the names (sets/tables) of the main administrative areas, any two adjacent areas can be broadcasted according to step S4414) or step S4415).

In an exemplary first broadcast example disclosed in the present invention, the earthquake early warning receiving end has a display screen and a speaker. The pre-warning area i is an administrative area corresponding to the ith identifier in the main administrative area, i is any one of 1 to N, and may be an identifier of an area (for example, name characters, a city, a county, a district, and the like) in practical application, the pre-warning information of each pre-warning area may already be obtained, and an identifier of an administrative area at a epicenter position (for example, name characters, a city, a county, a district, and the like) may also be obtained. At this time, for example, N is 4, and the main administrative areas may include a pre-warning area 1, a pre-warning area 2, a pre-warning area 3, and a pre-warning area 4. According to the sequence of the identifiers, the early warning areas and the early warning information thereof are as follows: the earthquake center distance D1, the early warning time T1 and the estimated intensity I1 of the early warning region 1, the earthquake center distance D2, the early warning time T2 and the estimated intensity I2 of the early warning region 2, the earthquake center distance D3, the early warning time T3, the estimated intensity I3 of the early warning region 3, the earthquake center distance D4, the early warning time T4 and the estimated intensity I4 of the early warning region 4, the existence of D1, D2, D3, D4 (the unit can be kilometers), T1, T2, T3, T4 (the unit can be seconds) and I1, I2, I3 and I4 (the unit can be degrees), D1-D4 and T1-T4 can be all positive integers, and I1-I4 can be floating points which reserve 1 decimal point.

The early warning information of the early warning area 1 is used as the main broadcast information, and the early warning area 1 is the smallest one of the earthquake center distance (or early warning time) values. The early warning time T1, T2, T3, T4 in the following broadcast operation are all actual early warning time, and the executed broadcast operation may include:

mono broadcast, for example,

"ding dong, T1, T1-1, … …, 1, whining.

The broadcast operation performed may further include:

two-channel broadcasting is performed, for example,

channel 1, "ding dong, T1, T1-1, … …, 1, whining;

channel 2, "Y.Y level earthquake occurred in county of a certain province". The identifier of the administrative region of a county of a province as the epicenter position, Y.Y, is the seismic series, usually in the form of a number retaining a decimal number, i.e., Y.Y level earthquake.

The purpose of adopting the nearest early warning area for early warning is to prompt a user to know that an earthquake occurs and take emergency measures through information displayed on a display screen.

In the exemplary second broadcast example disclosed by the present invention, on the basis of the first broadcast example, the warning information in the warning area 4 may be used as the main broadcast information, and the warning area 4 is the one with the largest value of the epicenter distance (or warning time). The early warning time T1, T2, T3, T4 in the following broadcast operation are all actual early warning time, and the executed broadcast operation may include:

mono broadcast, for example,

"dingdong, T4, T4-2, … …, 10, 9, … …, 2, 1, whining" u;

as yet another example of an implementation of the method,

"Ding-dong, Y.Y-grade earthquake, T4-5, T4-7, … …, 10, 9, … …, 2, 1, Wu-in a certain province and county. The broadcasted characters take 4 seconds.

The broadcast operation performed may further include:

two-channel broadcasting is performed, for example,

channel 1, "dingdong, T4, T4-2, … …, 10, 9, … …, 2, 1, whining;

channel 2, "Y.Y level earthquake occurred in county of a certain province".

It is worth noting that compared with the first broadcast example, the countdown timing interval of the second broadcast example covers the countdown intervals of the early warning areas 1 to 3, so that voice broadcast countdown voice prompt can be synchronous with the presentation of early warning time change in the early warning picture in the whole early warning execution process.

In the third exemplary broadcast example disclosed by the invention, on the basis of the first broadcast example, the early warning information of each early warning area can be used as the main broadcast information, and the broadcast can be started by using the early warning information of the early warning area with the shortest early warning time. The early warning time T1, T2, T3, T4 in the following broadcast operation are all actual early warning time, and the executed broadcast operation may include:

mono broadcast, for example,

"a ding-dong sound is generated,

warning area 1, T1, T1-1, … …, 1,

early warning areas 2, T2-T1, T2-T1-1, … …, 1,

early warning areas 3, T3-T2, T3-T2-1, … …, 1,

the early warning area 4 is T4-T3, T4-T3-1, … …, 1 and whining.

The broadcast operation performed may further include:

two-channel broadcasting is performed, for example,

the sound channel 1, the ding-dong,

warning area 1, T1, T1-1, … …, 1,

early warning areas 2, T2-T1, T2-T1-1, … …, 1,

early warning areas 3, T3-T2, T3-T2-1, … …, 1,

an early warning area 4, T4-T3, T4-T3-1, … …, 1, whining;

channel 2, "Y.Y level earthquake occurred in county of a certain province".

It is worth noting that the third broadcast instance and the second broadcast instance can both enable the countdown voice prompt of the voice broadcast to be presented with the early warning time change in the early warning picture, and are synchronous in the whole early warning execution process, and meanwhile, the third broadcast instance can also enable the voice prompt to mention the names of the areas affected by the earthquake.

In an exemplary fourth broadcast example disclosed by the present invention, on the basis of the first broadcast example, if the warning time difference threshold is 5 seconds and T4-T3 is less than 5 seconds, the performing broadcast operation may include:

mono broadcast, for example,

"a ding-dong sound is generated,

warning area 1, T1, T1-1, … …, 1,

early warning areas 2, T2-T1, T2-T1-1, … …, 1,

the early warning area 4, T4-T2, T4-T2-1, … …, 10, 9, … …, 1, Wu ".

Two-channel broadcasting is performed, for example,

the sound channel 1, the ding-dong,

warning area 1, T1, T1-1, … …, 1,

early warning areas 2, T2-T1, T2-T1-1, … …, 1,

an early warning area 4, T4-T2, T4-T2-1, … …, 10, 9, … …, 1, whining;

channel 2, "Y.Y level earthquake occurred in county of a certain province".

It is worth noting that the fourth broadcast example also enables the voice broadcast countdown sound prompt to be synchronous with the presentation of the early warning time change in the early warning picture, and meanwhile, the fourth broadcast example can avoid the too fast broadcast jump of the early warning area with the too close early warning time when being broadcast, because two early warning areas with small early warning time difference may not have enough time to complete the whole early warning information broadcast of the two early warning areas.

It should be noted that, in each of the above broadcast examples, no matter whether mono broadcast or binaural broadcast is performed, the early warning frames displayed on the screen of the earthquake early warning receiving end are the early warning information of the multi-target early warning area, and the broadcasted countdown sound prompt is synchronized with the change of each early warning time in the early warning frames. The broadcasting mode of broadcasting two or more early warning areas can be called voice cut-in broadcasting, the voice cut-in broadcasting can be preferably performed on the voice broadcasting with long early warning time, for example, the early warning time T3 or T4 is longer than 20 seconds, and the voice cut-in broadcasting can achieve broadcasting adaptivity and has the characteristic of automation. In the embodiment of the present invention, the above-mentioned each early warning mode and the broadcast instance in the early warning mode may be enabled by default on the earthquake early warning receiving end according to the test and use effects, and may also be selected by the user.

The embodiment of the invention provides an earthquake early warning system. The multi-target earthquake early warning method in the embodiment of the invention also comprises the execution step of an earthquake early warning center, wherein the earthquake early warning center can be the earthquake early warning center. The multi-target earthquake early warning method can further comprise the following steps:

J1) receiving earthquake monitoring key information transmitted by an earthquake monitoring end;

J2) determining earthquake early warning basic parameters based on the earthquake monitoring key information;

J3) and pushing the earthquake early warning basic parameters to an earthquake early warning receiving end in real time.

The multi-target earthquake early warning method in the embodiment of the invention also comprises the step of executing the earthquake monitoring end, wherein the earthquake monitoring end can be the earthquake monitoring end. The multi-target earthquake early warning method can further comprise the following steps:

K1) processing earthquake wave information to obtain earthquake monitoring key information;

K2) and sending the earthquake monitoring key information to an earthquake early warning center.

It should be added that, in the above example, the designated identifier may be set by the user when the earthquake early warning receiving terminal is turned on and used, or the server of the earthquake early warning center issues the designated identifier to the earthquake early warning receiving terminal. The main administrative areas and the early warning information of the main administrative areas can be determined on a server of an earthquake early warning center or an earthquake early warning receiving terminal, according to the characteristics of the different screening modes, the early warning information of all the administrative areas can be determined in a traversal mode to be used immediately after screening is completed, and the early warning information of the main administrative areas can also be determined after the screening step is completed.

For earthquake early warning receiving ends in two areas, namely a main administrative area and a non-main administrative area, voice broadcasting and early warning picture presentation can be executed on the earthquake early warning receiving ends in the two areas when an earthquake happens actually, because emergency management departments need information of each administrative area, which is influenced by the earthquake, so as to carry out emergency decision and resource scheduling. On the basis that the user has further needs or based on the consideration of test and use effect, on the earthquake early warning receiving end in the non-main administrative area, for example, the early warning screen presentation and the voice broadcast are not executed, which is not a limited implementation manner in the embodiment of the present invention.

The invention can avoid that the area which is not affected by the earthquake is not reported to emergency management departments and other users, determines the main administrative area which is affected by the earthquake by screening the identifier of the administrative area, does not need to use the positioning position information of the earthquake early warning receiving end in each administrative area, achieves the purpose of reporting the early warning information of each area and position point which are covered with the earthquake sensation and the strong earthquake sensation, realizes the multi-target early warning of the areas/position points in the main administrative area, improves the rationality of the taken emergency measures and the allocated resources, and can effectively organize and coordinate the rescue force and the rescue goods and materials.

The earthquake early warning system can form simultaneous early warning of a plurality of target areas/position points aiming at an earthquake, and simultaneously perform early warning time countdown prompting, broadcasting and the like; the invention supports different early warning issuing strategies, namely reasonable collocation of voice prompt and screen display for earthquake early warning.
