Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Aiming at the technical problem, the embodiment of the invention provides a method for effectively carrying out earthquake early warning within the earthquake early warning time by broadcasting a voice broadcast packet with voice description, compared with the traditional early warning method of warning sound or countdown, the early warning method is simpler and clearer, whether the public is popular or not can clearly know that the earthquake early warning is currently used, the earthquake occurrence condition and the estimation influence before the earthquake wave is clearly known, and reasonable risk avoiding measures are taken after the early warning is received, so that the disaster reduction effect of the earthquake early warning can be effectively improved.

It should be noted that, in implementation, because the broadcasting time of the voice broadcasting packet needs to be controlled and the content is uncertain, how to ensure that the voice broadcasting packet can be accurately, clearly and completely broadcasted within the valuable earthquake early warning time of several seconds to tens of seconds is a difficulty in implementation of the present invention, compared with the existing single warning tone alarm and countdown alarm modes. How this difficulty is overcome by embodiments of the present invention will be described in detail in the following.

For convenience of understanding, before specifically describing the earthquake early warning method according to the embodiment of the present invention, the earthquake early warning system according to the embodiment of the present invention will be described.

Referring to fig. 1, a schematic structural diagram of a seismic early warning system according to an embodiment of the present invention is shown, which may include: the system comprises a plurality of earthquake monitoring terminals 101, an earthquake early warning server 102 and at least 1 earthquake early warning terminal 103; wherein the content of the first and second substances,

the earthquake monitoring terminal is connected with the earthquake early warning server and used for generating earthquake key information when the earthquake waves are monitored and sending the earthquake key information to the earthquake early warning server;

In the embodiment of the invention, the earthquake monitoring terminal is preset near the epicenter to monitor earthquake waves, and when the earthquake waves are monitored, the earthquake monitoring terminal sends the earthquake key information obtained after the earthquake waves are analyzed to the earthquake early warning server.

The earthquake early warning server analyzes the earthquake key information to obtain earthquake information and an earthquake disaster area, wherein the earthquake information comprises an earthquake starting moment, an earthquake center position, an early warning earthquake magnitude and an earthquake source depth, the earthquake center position at least comprises longitude and latitude, and the earthquake center position can also comprise an earthquake center place name. The earthquake affected area can be determined according to a preset earthquake center distance or the condition affected by the earthquake, for example, the earthquake affected area is defined by taking the earthquake center position as the center of a circle and the preset earthquake center distance as the radius; for example, the area with high earthquake influence is defined as earthquake affected area. The earthquake early warning server can send the earthquake information to each earthquake early warning terminal in the earthquake stricken area through multiple channels, or the earthquake early warning server calculates according to the earthquake information and the receiving position to obtain the earthquake early warning information, and then the earthquake early warning server sends the earthquake early warning information to each earthquake early warning terminal in the earthquake stricken area through multiple channels.

Earthquake early warning terminal can indicate the intelligent terminal who installs a calamity early warning voice broadcast software that has the voice playing instrument, and this intelligent terminal can be smart mobile phone, smart television, panel computer, intelligent audio amplifier, family thing networking device, intelligent wrist-watch and intelligent wearable equipment etc.. Referring to fig. 2, a schematic structural diagram of an earthquake early warning terminal according to an embodiment of the present invention is shown, including a receiving unit, an information processing unit, and a disaster voice early warning unit; the receiving unit receives earthquake information sent by the earthquake early warning server and sends the earthquake information to the information processing unit; the information processing unit processes the earthquake information to obtain earthquake early warning information and sends the earthquake early warning information to the disaster voice early warning unit; and the disaster voice early warning unit carries out earthquake early warning broadcast according to the earthquake early warning information. It should be noted that the receiving unit can also receive earthquake early warning information sent by the earthquake early warning server and send the earthquake early warning information to the disaster voice early warning unit; and the disaster voice early warning unit carries out earthquake early warning broadcast according to the earthquake early warning information.

Referring to fig. 3, a flowchart illustrating steps of a seismic early warning method according to an embodiment of the present invention is shown, where the method may specifically include the following steps:

step S301, acquiring earthquake early warning information, wherein the earthquake early warning information comprises earthquake early warning time and earthquake influence degree;

the earthquake early warning information can be obtained by calculating the earthquake information and the receiving position when the earthquake early warning terminal receives the earthquake information, and can also be obtained by calculating the earthquake information and the receiving position after the earthquake early warning server analyzes the earthquake key information to obtain the earthquake information.

It should be noted that the earthquake early warning information includes earthquake early warning time and earthquake influence degree, and also includes earthquake information. Before calculating the earthquake early warning time and the earthquake influence degree, firstly, calculating the distance between the longitude and latitude of the receiving place (the position where the earthquake early warning terminal is located) and the longitude and latitude of the earthquake center position to obtain the earthquake center distance. The earthquake early warning time can be obtained by calculating according to the earthquake center distance, the information receiving time and the earthquake-initiating time. The earthquake influence degree can be represented by the estimated intensity, wherein the estimated intensity can be calculated according to the following modes: and calculating to obtain the estimated intensity according to the earthquake-in-mid distance and the earthquake magnitude. For the same earthquake, the earthquake center is taken as the center, the influence and the damage degree are weaker and weaker along with the distance between the earthquake centers, and people in different areas feel different on the same earthquake.

Step S302, determining broadcast contents according to at least one of earthquake early warning time and earthquake influence degree, wherein the broadcast contents comprise voice broadcast packets;

in an embodiment of the present invention, the voice broadcast packet includes at least one of a broadcast content template and broadcast material, and the broadcast material includes a tremolo description. The broadcast content template refers to a sentence with a formatted sample, and may be a fixed sentence pattern, such as "earthquake, please avoid danger" or "earthquake occurs around the periphery, please avoid danger", and the fixed sentence pattern may be a pre-stored audio material, or may be a sentence pattern that needs to be filled with broadcast materials, such as "broadcast material a1+ nearby earthquake, local + broadcast material a 2" or "broadcast material a3+ arrives after an earthquake transverse wave arrives, please avoid danger". The voice broadcast duration of different broadcast content templates is different, if the voice broadcast duration of "earthquake, please keep away the danger" is 2 seconds, "broadcast material a1+ nearby earthquake, local will + broadcast material a 2" voice broadcast duration is 5 seconds.

Through adding the broadcast content template containing 'earthquake' voice when earthquake early warning, the public can quickly respond to the earthquake early warning as soon as hearing the broadcast of the voice broadcast packet. Even if only the broadcast material including the earthquake sensation description is broadcast, the description vocabulary with the earthquake sensation already indicates that the earthquake early warning is earthquake early warning, and the user can directly know the earthquake sensation and quickly make reasonable risk avoidance measures.

The broadcast material is determined according to the actual earthquake occurrence condition and the influence condition of the earthquake, and belongs to a variable, and the seismographic description belongs to one of the broadcast materials. The earthquake influence degrees of different earthquakes are different, the earthquake influence degrees of different earthquake intermediate distances of the same earthquake are different, and the corresponding earthquake feeling descriptions are also different. Referring to table 1, a corresponding relationship between the estimated intensity and the seismic sensation description is shown in the embodiment of the invention when the estimated intensity is used for representing the seismic influence degree.

TABLE 1

Prediction of intensity	Description of the sense of vibration
		Estimated intensity of less than 3.0 DEG	Slight vibration "
The estimated intensity is less than 5.0 degrees and less than or equal to 3.0 degrees	Strong sense of vibration "
		Estimated intensity is more than or equal to 5.0 DEG	Strong sense of vibration "

The estimated intensity is divided into a plurality of different levels, and corresponding seismic description is broadcasted according to the level of the estimated intensity of the location of the receiving position. The advantages are that: at present, the public generally knows the earthquake magnitude and is strange to the estimated intensity, and the public can judge the earthquake intensity of the location without the unknown estimated intensity and directly determine the intensity of the earthquake intensity, so that the public can make a reasonable risk avoidance decision in time, and the uncertainty of the user on the degree to be influenced is reduced.

For the same earthquake, the earthquake early warning time and the earthquake influence degree obtained by the earthquake early warning terminals with different earthquake center distances are different, so that the determined voice broadcast packets are different, namely the broadcast voice broadcast packets can only be broadcast content templates and can also only describe materials for earthquake senses, and of course, the broadcast materials can also be combined with the broadcast content templates. In the embodiment of the present invention, step S302 may include the following sub-steps:

step S302-01, selecting a target broadcast content template from a broadcast template library according to the earthquake early warning time;

substeps S302-02, and/or selecting a target seismographic description material of a corresponding seismographic description level from a broadcast material library according to the grade of the seismic influence degree;

step S302-03, when the target broadcast content template is in an audio format, taking the target broadcast content template as a voice broadcast packet;

step S302-04, when the target earthquake sensation description material is in an audio format, taking the target earthquake sensation description material as a voice broadcast packet;

and substeps 302-05, when the target broadcast content template and the target earthquake sensation description material are in a text format, filling the target earthquake sensation description material into the target broadcast content template, and converting the target earthquake sensation description material into an audio format to generate the voice broadcast packet.

The embodiment of the invention selects the target playing content template which can be completely played in the earthquake early warning time, and needs to transmit the most key and effective information to the user in a short time. If the earthquake early warning time is 60 seconds, a target broadcast content template with the voice broadcast time length of 5-7 seconds can be selected, and the target broadcast content template can be played repeatedly in the 60 seconds in a circulating mode; if the earthquake early warning time is 5 seconds, a target broadcast content template with the voice broadcast time length of 2-4 seconds can be selected. Referring to table 1, the earthquake sensation description level corresponds to the estimated intensity level, and if the estimated intensity of an earthquake is 6.0 degrees, the determined target earthquake sensation description material is "strong earthquake sensation".

In order to facilitate management of various broadcast content templates and broadcast materials, the broadcast template library and the broadcast material library are created in the embodiment of the invention, and in the respective libraries, the broadcast content templates and the earthquake sensation description materials can be prestored in an audio format or a text format. When the broadcast content template is prestored in an audio format, the selected target broadcast content template can be directly extracted from the broadcast template library as a voice broadcast packet for broadcasting according to the earthquake early warning time, and the broadcast content template is a fixed sentence pattern, such as 'earthquake, please avoid danger' or 'surrounding earthquake, please pay attention to avoid danger'. When the seismograph description material is prestored in an audio format, according to the earthquake influence degree grade of the current earthquake, the selected target seismograph description material can also be directly extracted from the broadcast material library to be used as a voice broadcast packet to broadcast, if the voice broadcast packet is 'strong seismograph' or 'slight seismograph'. When the broadcast content template and the earthquake sensation description material are prestored in a character format, the target broadcast content template generally selects a sentence pattern needing to be filled with the broadcast material, then the target earthquake sensation description material is filled into the target broadcast content template as the broadcast material to obtain a broadcast text, if the target earthquake sensation description material is filled into the target broadcast content template in a slight earthquake occurrence mode, the broadcast text is locally broadcasted in the + broadcast material', the broadcast text in the earthquake occurrence mode is locally broadcasted, the + earthquake sensation in the local broadcast text is slightly broadcasted, the broadcast text is converted into an audio format, and a voice broadcast packet is generated, so that a user can know the influence degree of the earthquake most directly and clearly.

When a site earthquake occurs, the voice broadcast packet to be broadcast can be determined according to at least one of earthquake early warning time and earthquake influence degree. If only broadcasting the voice broadcast packet of 'earthquake, please avoid danger', or only broadcasting the voice broadcast packet of 'strong earthquake feeling', or alternatively broadcasting the two voice broadcast packets of 'earthquake, please avoid danger' and 'strong earthquake feeling' within the earthquake early warning time, or only broadcasting the voice broadcast packet after combining the broadcast content template and the earthquake feeling description material. If the earthquake comes, the earthquake is slight, so that the public can quickly know the earthquake and the influence degree, and the public can be guided to quickly avoid the danger.

In the embodiment of the invention, in order to enable a user to know the earthquake condition more clearly, the broadcast material library further comprises an earthquake-initiating time material, an earthquake-center position description material, a pre-warning earthquake-level description material and a receiving position description material, wherein the earthquake-initiating time material and the pre-warning earthquake-level description material are directly extracted from earthquake information and are stored in the broadcast material library. The epicenter position description material and the receiving position description material are obtained by processing the original description of the epicenter position and the original description of the receiving place position, and the method comprises the following steps:

obtaining an original description of the epicenter position and an original description of the recipient position;

extracting keywords in the original description of the epicenter position to obtain a epicenter position description material;

and extracting keywords in the original description of the receiving place position to obtain the receiving place position description material.

In the embodiment of the invention, the original description of the epicenter position can be calculated, analyzed and determined by the earthquake early-warning server according to the longitude and latitude of the epicenter position and then sent to the earthquake early-warning terminal, or can be directly calculated and determined by the earthquake early-warning terminal according to the longitude and latitude of the epicenter position, and belongs to an administrative region name, such as an administrative region name of province, city and county. The original description of the receiving place position can be obtained by calculating the longitude and latitude of the current positioning by the earthquake early warning terminal, can also be obtained by dividing the longitude and latitude of the position where the earthquake early warning terminal is manually input by an installer, and can also be directly determined by the earthquake early warning server based on the longitude and latitude of the position where the earthquake early warning terminal is located and then sent to the earthquake early warning terminal, wherein the earthquake early warning terminal also belongs to an administrative region name, such as the administrative region name of province, city and county.

Based on the core idea that the most important early warning information needs to be provided for a user as quickly as possible within a short early warning time, in order to enable the user to quickly identify and know the earthquake early warning information within the shortest time and ensure the simplicity and clarity of the earthquake center position information, the earthquake center position description material (key words of the original description of the earthquake center position) is called short place name rather than full place name because the full place name is longer, for example, the city of the autonomous state of the dehong Dai nationality of Jingpo nationality of Yunnan province. In an embodiment of the present invention, the keyword in the original description of the epicenter location is "provincial place name plus short name of prefecture and county place name", such as "Sichuan Changning", "inner Mongolian Xinghe and". That is, the keywords to be extracted in the embodiment of the present invention do not include the words "national autonomous region" and "province", because the words such as "province" and "national autonomous region" are broadcasted to increase the length of the speech words of the speech broadcast packet, which may result in an increase in the time for the user to acquire the key information. Similarly, the keywords in the district-level place name to be extracted in the embodiment of the present invention do not include words such as "city", "county-level city", "county", self-government flag, forest region ", and" city "," self-government ", self-government flag", "forest region", and "special district" in the special district, and certainly, except for a special example, the word "pei county" may be broadcast in pei county.

Because the disaster information received by the user at the receiving place can be quickly acquired only by the district-level place name of the place, and the district-level place name is more familiar to the user, in order to reduce the number of unnecessary words for voice broadcast, the receiving place position is different from the epicenter position, the receiving place position description material can only broadcast the city-level place name and the district-level place name or only broadcast the district-level place name without the provincial place name, namely, the keyword in the original description of the receiving place position is 'short for the district-level place name'. In addition, no matter which way the receiving location is obtained, the location can be known in advance, so that the receiving location can be processed in advance and stored as receiving location description material. Of course, the receiving location may also be directly replaced with a fixed word, e.g., "local".

For the broadcast materials, the embodiment of the present invention may obtain at least one of the earthquake-initiating time material, the earthquake location description material, the early warning earthquake level description material, and the receiving location description material from the broadcast material library, and generate the following voice broadcast packet:

(1) and filling at least one of the earthquake-initiating moment material, the earthquake-center position description material, the early warning earthquake level description material and the receiving position description material into a target broadcast content template, converting the template into an audio format, and generating a voice broadcast packet. In an example, the voice broadcast packet is a "sichuan 5.8-level earthquake", wherein the "sichuan" is a description material of the earthquake center position, the "sichuan" is a template of the target broadcast content, and the "5.8-level" is a description material of the early warning earthquake level. For example, the voice broadcast packet is "that the seismic transverse wave is about to reach the XX area", where "that the seismic transverse wave is about to reach" is a target broadcast content template, and "XX area" is a receiving location description material. In an example, the voice broadcast packet is "22 hours, 55 minutes, that is, a sichuan earthquake occurs", wherein the "x earthquake occurs" is a target broadcast content template, the "sichuan earthquake" is a epicenter position description material, and the "22 points, 55 minutes", is an earthquake occurrence time material.

(2) And filling at least one of the earthquake-initiating moment material, the earthquake-center position description material, the early warning earthquake level description material and the receiving position description material and the target earthquake feeling description material into a target broadcast content template, and converting the target earthquake feeling description material into an audio format to generate a voice broadcast packet. In an example, the voice broadcast packet is "21 hours and 47 minutes", the yunnan skilful house generates 5.0-level earthquake, the XX zone is slight in earthquake sense, and attention is avoided ", wherein the" yunnan skilful house "is a seismic center position description material, the XX zone" is a receiving position description material, the "slight in earthquake sense" is a target earthquake sense description material, the "{ hour } minute" is an earthquake generation time material, and the "} level" is an early warning earthquake level description material.

It should be noted that when a large magnitude earthquake occurs, the voice broadcast packet should not contain the description material of the early warning magnitude, because the large magnitude is easily broadcast to make the public think of the extremely strong destructive power and the extremely high casualties generated by the large earthquakes such as 8.0 level Wenchuan earthquake, etc., so that the public may generate a panic and a mess, which affects the public to avoid danger. In an optional embodiment of the present invention, the following method is further included:

comparing the early warning magnitude in the seismic information with a preset magnitude threshold;

and when the early warning magnitude in the earthquake information is greater than or equal to a preset magnitude threshold, the generated voice broadcast packet does not contain early warning magnitude description materials. In an example, when the magnitude is greater than 6.0, the voice broadcast packet does not include a pre-warning magnitude description material, and is described by adopting a strong earthquake.

In an optional embodiment of the invention, in order to facilitate a user to clearly know earthquake early warning time, the broadcast content further includes a countdown prompt, the countdown prompt includes at least one of an influence prompt tone and a digital countdown, and the influence prompt tone and the digital countdown are prestored in an audio format in a countdown prompt library; in the embodiment of the present invention, step S302 may include the following sub-steps:

step S302-11, determining a target digital countdown time with a corresponding broadcast length from a countdown prompt library according to the earthquake early warning time;

and a substep S302-12, determining target influence prompt tones of corresponding prompt levels from a countdown prompt library according to the earthquake influence degree grade of the earthquake influence degree.

In the embodiment of the invention, the digital countdown is used for broadcasting the time of the arrival of the seismic waves to users, so that the countdown is carried out on the time of the arrival of the seismic waves, particularly the transverse waves, in the disaster area when earthquake early warning is carried out. The countdown prompting library is prestored with complete digital countdown, such as 100-second digital countdown, and according to the received earthquake early warning time, the target digital countdown with the corresponding broadcast length is pointed from the complete digital countdown in the countdown prompting library for broadcasting. For example, the earthquake warning time is 16 seconds, and the selected target digital countdown is broadcast starting from 16 seconds, for example, "16, 15, 14, 13, 12, 11, 10, 9, 8, 7, 6, 5, 4, 3, 2, 1". Or the countdown prompt library is pre-stored with 1-10 seconds of digital countdown, and digital countdown voice synthesis is carried out according to the received earthquake early warning time, for example, 28 is synthesized by 2 and 8, and 18 is synthesized by 10 and 8, so that the size of the voice file of digital countdown pre-stored in the countdown prompt library can be greatly reduced.

It should be noted that, because countdown broadcasting needs to read the second broadcasting in real time, the broadcast digit countdown adopts roman digits, and roman digits greater than 9 are two digits, so that when voice broadcasting is performed, the broadcasting time length of each two digits is greater than that of each one digit. Preferably, when the broadcast is greater than 10, the broadcast is performed every second, for example: when the two-digit broadcast digit countdown is performed, the difference value between every two Roman digits is 2.0 seconds, so that the method has the advantages that the phenomenon that each Roman digit needs to be broadcast urgently is avoided, further, the digit countdown broadcast can be performed at a slow speed, a user can hear clearly, and the user can feel less nervous about coming. Also, it is advantageous that the impact tones can be added at every second interval. When the broadcast single digit numbers are counted down, the difference value between every two Roman digits is 1.0 second because the early warning time is short. For example, the target number is down to "16, 14, 12, 10, 9, 8, 7, 6, 5, 4, 3, 2, 1".

The influence prompt tones are also pre-stored in the countdown prompt library in various types, each type has a corresponding prompt level, the earthquake influence degrees of different earthquakes are different, and the corresponding influence prompt tones are also different, and a table 2 is referred to show the corresponding relation between the estimated intensity and the influence prompt tone when the estimated intensity is adopted to represent the earthquake influence degree in one embodiment of the invention.

TABLE 2

The influence prompt tone is combined with digital countdown, if the estimated intensity is estimated intensity a, the influence prompt tone is influence prompt tone a, and the countdown prompt specifically comprises the following steps: ding-dong, 29, 27, 25 … to end; the predicted intensity is predicted intensity b, the influence prompt tone is influence prompt tone b, and the countdown prompt specifically comprises the following steps: ding-dong, 29, tic, 27, tic, 25 … to end; the estimated intensity is estimated intensity c, the influence prompt tone is influence prompt tone c, and the countdown prompt specifically comprises the following steps: ding-dong, 29, tic, 27, tic, 25 …. Clearly, the "tic" is more dramatic and has a stronger cue effect than the "tic" and does not add the "tic" sound to the digital countdown, significantly alerting the user to the more strongly affected earthquake. Wherein, ding-dong means that an earthquake occurs and early warning information is received.

And step S303, broadcasting the broadcast content within the earthquake early warning time.

During specific implementation, voice broadcasting packets and countdown prompts can be combined and broadcasted according to certain broadcasting conditions according to earthquake early warning time, so that the broadcasting contents are clear, accurate, simple and clear. The broadcast condition can be determined by the following modes:

firstly, according to the sum of preset inter-cut interval duration and voice broadcast duration of the voice broadcast packet, or according to the voice broadcast duration of the voice broadcast packet, determining inflection point duration.

In the embodiment of the invention, the inflection point time length is the minimum time length which ensures that the voice broadcast packet can be normally broadcast in the earthquake early warning time. As described above, the voice broadcast packet in the embodiment of the present invention may be a pre-stored audio file, or may be temporarily generated from a text to audio file. When the voice broadcast packet is a pre-stored audio file, the pre-stored target broadcast content template or the target broadcast content template is directly extracted from the corresponding library to be broadcast, and the time length of the turning point can be determined at least according to the time length of the voice broadcast packet. For example, when the voice broadcast packet is a pre-stored audio file, the time length is not generated, the voice broadcast time length of the voice broadcast packet is 5 seconds, and the inflection point time length is at least 5 seconds. When the voice broadcast packet is temporarily generated by converting text into audio, the temporarily generated voice broadcast packet has a generation time, and the voice broadcast packet can be generated in the first inter-cut interval time or the last inter-cut interval time, for example, the inter-cut interval time is 3 seconds, the voice broadcast time of the voice broadcast packet is 6 seconds, and the inflection point time is 9 seconds.

The inter-cut interval duration can be preset, the preset setting comprises self-adaptive setting and fixed setting, the self-adaptive setting means that the self-adaptive setting can be in self-adaptive correlation with the voice broadcast duration, for example, the self-adaptive setting is 40% -200% of the voice broadcast duration, namely, the first type, the inter-cut interval duration can be the same as the voice broadcast duration, and the inter-cut interval duration can be changed along with the change of the voice broadcast duration of the voice broadcast packet; second, the inter-cut interval duration is different from the voice broadcast duration, for example, the inter-cut interval duration is 0.4 times, 0.6 times, 0.8 times, 1.2 times, 1.4 times, 1.6 times, 1.8 times, or 2.0 times the voice broadcast duration. The fixed setting means that the inter-cut interval duration may be set to a fixed value, for example, one of 4 seconds, 6 seconds, 8 seconds, and 10 seconds in length.

It should be noted that, in the specific implementation, if the earthquake influence degree is small, the receiving area is not damaged, and meanwhile, when the earthquake early warning time is long, the user does not need to acquire information about earthquake early warning in the voice inter-cut, and the inter-cut interval duration can be set to be long. Otherwise, the voice broadcast packet can be broadcast firstly or the inter-cut time length can be reduced under the condition of ensuring the normal generation of the voice broadcast packet.

And secondly, comparing the earthquake early warning time with the inflection point duration.

The embodiment of the invention can compare the current earthquake early warning time with the inflection point time according to a certain period (such as every second or every inflection point time), and when the earthquake early warning time is longer than the inflection point time, the voice broadcast packet can be continuously broadcast, otherwise, the voice broadcast packet cannot be continuously broadcast. Therefore, step S303 of the embodiment of the present invention may include the following sub-steps:

step S303-01, when the earthquake early warning time is longer than the inflection point duration, broadcasting the voice broadcast packet at least once within the earthquake early warning time, or broadcasting the countdown prompt and broadcasting the voice broadcast packet at least once;

the earthquake early warning time is at least one, it is long with at least one to insert the interval time the voice broadcast is long to set up in turn, at least one it is long to insert the interval time the voice broadcast is long to be right in the interval time the count down suggestion is broadcast, at least one it is long to be right in the voice broadcast is broadcast the packet is broadcast or is right in the voice broadcast the interval time the count down suggestion with the voice broadcast packet is broadcast, works as when the voice broadcast packet is for interim the generation, at first in the interval time of inserting or the last interval time of inserting, generate the voice broadcast packet.

Under the condition that the voice broadcast packet is temporarily generated by converting characters into audio, the temporarily generated voice broadcast packet has a generation time, so that in the early warning process of the same earthquake, when the voice broadcast packet is unchanged, the voice broadcast packet can be generated within the time of a first inter-cut interval, and then the voice broadcast packet is repeatedly broadcast in turn without generating the same voice broadcast packet within the time of each inter-cut interval, thereby being beneficial to reducing the workload of an equipment system and saving resources.

In addition, in the early warning process of the same earthquake, the voice broadcast packet is broadcast in a changeable mode, and different voice broadcast packets can be generated in the first inter-cut interval duration before being broadcast. The same, different voice broadcast package only generates once, set up different voice broadcast package in the system and report constantly at corresponding broadcasting can, so generate different voice broadcast package and can save the number of times that the generation time and system generated, reduce system load.

When the earthquake early warning information is obtained, the earthquake early warning time is a specific determined numerical value, when the earthquake early warning time is larger than the inflection point time, the broadcasting times of the voice broadcasting packets can be judged according to the alternately set inter-cut interval time and the voice broadcasting time, and the corresponding broadcasting time node of at least one voice broadcasting packet in the earthquake early warning time is judged. Under the condition that the earthquake early warning time is determined, judgment before each voice broadcast packet is broadcast is not needed, the judgment times can be reduced, the system workload is reduced, and the load is reduced.

In the embodiment of the present invention, the existence of the inter-cut interval duration means: the countdown prompt is broadcasted in the inter-cut interval duration and is used for informing the user of the earthquake wave and the required duration of the location in real time, so that the user is reminded of avoiding risks quickly, meanwhile, the voice broadcast packet can be generated for the first time in the inter-cut interval duration and then broadcasted, and the sufficient time for converting the character format of the voice broadcast packet into the audio format is guaranteed.

In addition, also can be according to the length is long in the voice broadcast of voice broadcast package, and length is long when confirming the flex point, does not need the text format to convert audio format condition into in the voice broadcast package, and length is long can regard as length when the flex point is long in the voice broadcast, or before the voice broadcast packet is reported the inter cut interval has been generated during long, need not to regenerate the voice broadcast package, length can be according to length is long when confirming the voice broadcast of voice broadcast package.

When the target broadcast content template is in an audio format or the target earthquake sensation description material is in an audio format and serves as a voice broadcast packet, the voice broadcast packet can be broadcast firstly, then the countdown prompt is broadcast within the inter-cut interval duration, or the countdown prompt is broadcast within the inter-cut interval duration firstly, and then the voice broadcast packet is broadcast.

And when the target broadcast content template and the target earthquake sensation description material are in a character format, filling the target earthquake sensation description material into the target broadcast content template, converting the target earthquake sensation description material into an audio format, and generating the voice broadcast packet. At this moment, because the characters are converted into the audio format, a generating time length is needed, the countdown prompt is broadcasted in the first inter-cut interval time length firstly, meanwhile, the character format of the voice broadcast packet is converted into the audio format, and the generated voice broadcast packet is broadcasted after the first inter-cut interval time length.

And substeps 303-02, when the earthquake early warning time is less than or equal to the inflection point duration, broadcasting the countdown prompt within the earthquake early warning time.

For the above substeps, exemplified are: the earthquake early warning time is 61 seconds, namely the digital countdown of the countdown prompt is 61 seconds, the preset inter-cut time length is 6 seconds, the voice broadcast time length of the voice broadcast packet is 6 seconds, and the determined inflection point time length is 12 seconds. Firstly, broadcasting countdown prompts 61, 59 and 57 … … in a first inter-cut interval duration (voice broadcasting packets are generated in the interval duration), namely, the countdown prompts are broadcasted for at least 6 seconds, and after the countdown prompts are broadcasted, broadcasting a first voice broadcasting packet in the first voice broadcasting duration (6 seconds) is started; after this voice broadcast packet reports, report 6 seconds's countdown suggestion again in second inter cut interval duration, report above-mentioned voice broadcast packet (6 seconds) … … again so recirculation to present earthquake early warning time less than or equal to this voice broadcast packet broadcast during long (6 seconds), stop the report of broadcasting of voice broadcast packet, remaining time has continued completely not enough to report next voice broadcast packet this moment, report countdown suggestion instead, if 6, 5, 4, 3, 2, 1.

The following are exemplified: the earthquake early warning time is 30 seconds, the voice broadcast time of the voice broadcast packet 'earthquake comes and please pay attention to risk avoidance' is 5 seconds, the voice broadcast time is prestored as an audio file and does not need to be generated, and the determined inflection point time is 5 seconds. The voice broadcast packet of 'earthquake coming and please pay attention to risk avoidance' can be repeatedly broadcast within the 30 seconds, and the voice broadcast packet and the countdown prompt can be broadcast alternately. When the countdown prompt is broadcast first, the countdown prompt with the countdown prompt is started from 30 seconds, and when the countdown prompt is broadcast first, the countdown prompt with the preset inter-cut interval duration of 6 seconds can be broadcast, for example, the countdown prompt of "30, tic, 28, tic … …" of 6 seconds is broadcast first, and then the voice broadcast packet of 5 seconds "comes to an earthquake and please pay attention to avoid the danger" is broadcast. At the moment, the current earthquake early warning time is changed into 19 seconds, the duration is still more than 5 seconds of the inflection point, the voice broadcast packet can be selected to be repeatedly broadcast within the current earthquake early warning time (19 seconds) ' earthquake comes and please pay attention to risk avoidance ', or the voice broadcast packet ' earthquake comes and please pay attention to risk avoidance ' and countdown prompt are selected to be alternately broadcast within the current earthquake early warning time (19 seconds) '.

When the current earthquake early warning time is changed into 19 seconds, if the voice broadcast packet 'strong earthquake feeling' (the voice broadcast packet is generated in the first inter-cut interval time or is pre-stored) with the voice broadcast time length of 3 seconds is considered to be replaced, the time length of the determined inflection point is 3 seconds, the voice broadcast packet 'strong earthquake feeling' and the broadcast countdown prompt … … with the preset inter-cut interval time length (such as 6 seconds) can be broadcast alternately in the earthquake early warning time of 19 seconds until the earthquake early warning time is less than the last determined inflection point time length, the broadcasting of the voice broadcast packet is stopped, and only the countdown prompt is broadcast instead, such as '3, 2 and 1'.

The above two examples are only two optional examples of the embodiment of the present invention, and for reasons of space, the present invention does not describe the combination manner of each broadcast content.

In practice, the countdown prompting and the voice broadcasting packet can be respectively broadcasted by two audio tracks, and one audio track can alternatively broadcast between the countdown prompting and the voice broadcasting packet. In an optional embodiment of the present invention, when the countdown prompt and the voice broadcast packet are broadcast at least once respectively in two audio tracks; it is right the countdown suggestion report with when the voice broadcast package was reported at least once, can include following two kinds of modes:

(1) when the voice broadcast packet is broadcast through the first audio track, the second audio track stops broadcasting the countdown prompt; when the countdown prompt is broadcasted through the second audio track, the first audio track stops broadcasting the voice broadcast packet;

(2) when broadcasting the voice broadcast packet through the first audio track, broadcasting the countdown prompt through the second audio track, and adjusting the volume of the countdown prompt to be smaller than that of the voice broadcast packet.

When the double-track is adopted, in order to enable the auditory sense of a user to be clearer to the content of the voice insertion, the countdown prompt is prevented from generating larger interference to the voice insertion when two sounds are broadcast simultaneously, the countdown prompt can be stopped being broadcast or the volume of the countdown prompt is reduced in the period of broadcasting the voice broadcast packet. For example, in the time period of broadcasting the voice broadcast packet, the volume of the countdown prompt is adjusted to 20-80% of the volume of the voice broadcast packet.
