Description

Technical Field

[0001] This invention relates to the field of earthquake early warning technology, and more specifically to an optimized disaster early warning method, an optimized disaster early warning device, and an optimized disaster early warning equipment. Background Technology

[0002] Existing earthquake early warning systems will issue warnings only when earthquakes reach certain threshold conditions. However, the existing earthquake early warning thresholds are all fixed thresholds. When an earthquake occurs or an aftershock occurs, especially when there are multiple earthquakes or swarms, i.e., multiple earthquakes occur in similar or different areas within a certain period of time, multiple warnings will be issued to users.

[0003] However, users in areas with different seismic intensities have different needs for earthquake early warning. Users who are close to the epicenter and will experience significant damage need timely early warnings to improve their user experience. Users who are some distance from the epicenter and will not experience significant damage need early warnings, especially at night, to avoid disturbing their sleep and improve their user experience. Existing earthquake early warning methods based on fixed thresholds result in a poor user experience for all users.

[0004] In summary, existing earthquake early warning methods based on fixed thresholds cannot meet the needs of users in areas with different earthquake intensities, resulting in a poor user experience. Summary of the Invention

[0005] In view of this, the present invention aims to propose an optimized disaster early warning method, apparatus and equipment to at least solve the problem of poor user experience of existing earthquake early warning methods.

[0019] Other features and advantages of the present invention will be described in detail in the following detailed description section. Attached Figure Description

[0020] The accompanying drawings, which form part of this invention, are used to provide a further understanding of the invention. The illustrative embodiments of the invention and their descriptions are used to explain the invention and do not constitute an undue limitation of the invention. In the drawings:

[0021] Figure 1 This is a flowchart illustrating an optimized disaster early warning method provided by one embodiment of the present invention;

[0022] Figure 2 This is a schematic diagram of the structure of an optimized disaster early warning device provided in one embodiment of the present invention. Detailed Implementation

[0023] It should be noted that, unless otherwise specified, the embodiments and features described in this invention can be combined with each other.

[0024] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0025] Figure 1 This is a flowchart illustrating an optimized disaster early warning method provided by one embodiment of the present invention. Figure 1 As shown, an optimized disaster early warning method includes:

[0026] S01. Obtain the rapid earthquake intensity report result of the first earthquake, wherein the rapid earthquake intensity report result includes a first mapping relationship between geographical location and earthquake intensity.

[0027] Earthquake intensity rapid reporting refers to the rapid calculation of the earthquake impact at each observation point after an earthquake occurs, based on the observation of ground motion records by earthquake monitoring instruments. The earthquake impact can be expressed by instrument intensity and / or ground motion parameters, thereby providing a complete earthquake impact field and rapidly releasing it, providing a basis for casualty estimation, economic loss assessment, earthquake emergency rescue decision-making, and engineering emergency repair decision-making.

[0028] After an earthquake occurs, a rapid earthquake intensity report will be generated within minutes. The rapid earthquake intensity report includes earthquake intensity data and can also be displayed in the form of an earthquake intensity map. The central server can also calculate the intensity value of the user terminal at its current location based on the earthquake intensity report and send it to the user terminal.

[0029] The first mapping relationship is represented in the form of intensity contour lines in the earthquake intensity rapid report. The earthquake intensity rapid report will also define the geographical range of intensity. Alternatively, the first mapping relationship can be represented in the form of intensity value point distribution map in the earthquake intensity rapid report map.

[0030] S02. Based on the first mapping relationship and the preset mapping relationship between earthquake intensity and earthquake early warning threshold, determine the second mapping relationship between geographical location and earthquake early warning threshold.

[0031] The first mapping relationship reflects the relationship between different geographical locations and earthquake intensity for a certain earthquake. Combining the relationship between earthquake intensity and earthquake early warning threshold, the earthquake intensity in the first mapping relationship is mapped to the earthquake early warning threshold, thus obtaining the mapping relationship between geographical location and earthquake early warning threshold. In this implementation, it is referred to as the second mapping relationship.

[0032] S03. Determine the target earthquake early warning threshold corresponding to the current location based on the current location and the second mapping relationship.

[0033] In this embodiment, the current location is preferably the location of the early warning device or the early warning server.

[0034] Early warning devices or servers deployed in different locations obtain the corresponding target earthquake early warning threshold based on their own location and the second mapping relationship, and then issue earthquake early warnings based on the target earthquake early warning threshold.

[0035] The current location here may also be the selected location. The user selects the location they are interested in on the early warning device, and the early warning device returns the corresponding target earthquake early warning threshold to the user who submitted the query based on the second mapping relationship.

[0036] The early warning device can be a user's own terminal, television, tablet computer, or other device, or it can be a professional terminal for emergency personnel. Through the above implementation methods, different adjustment strategies can be adopted for users in areas with different earthquake intensities when an earthquake occurs, thereby improving the user experience in earthquake early warning.

[0037] In some embodiments of the present invention, the method further includes: if the current location is in a key alert area, and the distance between the epicenter of the second earthquake that triggers the target earthquake early warning threshold and the epicenter of the first earthquake is within a first preset distance range, and the time interval between the occurrence time of the second earthquake and the occurrence time of the first earthquake is within a preset time range, then the target earthquake early warning threshold is adjusted.

[0038] In some earthquake early warning scenarios, emergency personnel need to understand the occurrence and impact of earthquakes within their jurisdiction in order to prepare for potential aftershocks or swarms. Furthermore, government emergency personnel may be located far from the epicenter, making intensity thresholds insufficient as a warning criterion. A method for delineating key alert areas is provided below. Within these key alert areas, if the distance between the epicenter of the second earthquake that triggers the target earthquake early warning threshold and the epicenter of the first earthquake is within a first preset distance range, and the time interval between the occurrence times of the second earthquake and the first earthquake is within a preset time range, then the target earthquake early warning threshold determined in step S03 needs further adjustment to adapt to the early warning requirements of the key alert areas.

[0039] In some embodiments of the present invention, the key reminder area is obtained through the following steps: generating area lists for different service areas respectively; obtaining a selection instruction for the area list, and generating an area containing the location of the first earthquake epicenter that matches the selected service area as the key reminder area.

[0040] The regional list here can be set by administrative division, providing a list of townships, counties, cities, and provinces including the epicenter of the first earthquake for users to select. Users can select the important areas they need to focus on based on their service area, generating township-level areas, county-level areas, or areas from the list that include the epicenter of the first earthquake as key alert areas. For example, if the jurisdiction of provincial emergency personnel covers the entire province, then the entire province will be the key alert area. If the jurisdiction of regional emergency personnel is a specific area or region within the province, such as Ma'erkang City, then they can select from the city-level list.

[0041] In some embodiments of the present invention, the key reminder area is obtained by the following steps: determining the reference point of the key reminder area based on the location of the first earthquake epicenter;

[0042] The scope of the key warning area is determined based on the magnitude of the first earthquake;

[0043] The key reminder area is obtained based on the reference point and the range.

[0044] Earthquake early warning systems designate key alert areas. These areas can be the administrative region where the epicenter is located, or a region with a radius of XX kilometers centered on the epicenter. The radius of this area is determined by the magnitude of the previous earthquake; for example, a magnitude 5-6 earthquake has a radius of 50 kilometers, a magnitude 6-7 earthquake has a radius of 100 kilometers, and a magnitude 7-8 earthquake has a radius of 200 kilometers. The duration of the key alert area designation can be 6 hours, 12 hours, 18 hours, 24 hours, or even longer. Of course, the designation of key alert areas can be done manually by emergency personnel, or it can be adjusted and revised by emergency personnel based on the key alert areas automatically designated by the system.

[0045] In some embodiments of the present invention, the method further includes: modifying the generated key reminder area according to the user's modification instructions; the modification instructions include at least one of: modifying the area size, modifying the area center, and reselecting the area.

[0046] In the previous embodiment, the system generated the reference points and ranges according to preset rules. However, since the setting of the key reminder area needs to be determined according to different scenarios, it has great flexibility. Therefore, this embodiment provides a variety of modification commands. Among them, modifying the area size is used to modify the range of the aforementioned key reminder area, modifying the area center is used to modify the reference point of the aforementioned key reminder area, and reselecting the area is used to directly reselect the key reminder area.

[0047] In some embodiments of the present invention, the reselection of the area includes: reselecting the area based on the input area name or location name; or reselecting the area based on the input latitude and longitude information; or reselecting the area based on an area selection operation. For example, the specific steps include: after the earthquake early warning ends, the system prompts the user whether to enter the swarm / aftershock observation mode. If the emergency personnel click "yes," the system further prompts the emergency personnel whether to designate XX City (the area where the epicenter is located) as a key alert area. If the emergency personnel click "yes," XX City is designated as a key alert area. Afterwards, the emergency personnel can manually add or delete key alert areas, and can also modify the duration of the key alert area. If the emergency personnel select "no," they need to manually add key alert areas. Manually adding key alert areas can be done by inputting the name of the area / location, by adding latitude and longitude information, or by adding them based on the user's area selection operation.

[0048] In another example, specifically after an earthquake warning ends, the system prompts the user whether to enter swarm / aftershock observation mode. If the emergency responder clicks "yes," the system further prompts the user whether to designate an area within a radius of XX kilometers centered on a latitude and longitude point (XXX.XX, XXX.XX) as a key alert area. If the emergency responder clicks "yes," this area is designated as a key alert area. The emergency responder can then manually add or delete key alert areas and modify the duration of the key alert area. If the emergency responder selects "no," they need to manually add key alert areas. Key alert areas can be added manually by entering the name of the area / location, by using latitude and longitude information, or by selecting an area based on the user's location.

[0049] In some embodiments of the present invention, after obtaining the key reminder area, the method further includes: prompting the user if a previous key reminder area exists; and updating or merging multiple key reminder areas according to the obtained operation instructions.

[0050] In some extreme scenarios, such as in multi-earthquake scenarios where multiple large earthquakes affect a certain area simultaneously or sequentially, the designated key alert areas may be two or more regions. Provincial emergency personnel need to monitor all key alert areas simultaneously. In the aforementioned steps of designating key alert areas, the system can sequentially prompt the user to designate key alert areas, for example, asking whether to designate City XX1 (the area where the epicenter of earthquake 1) as a key alert area, then asking whether to designate City XX2 (the area where the epicenter of earthquake 2) as a key alert area, and so on, until all key alert areas for all earthquakes occurring in the multi-earthquake scenario have been designated. In this implementation, after City XX2 is subsequently designated as a key alert area, the previously designated key alert area for City XX1 is retained; the key alert area at this point is the union of the two.

[0051] When a user selects to update, the previously designated XX1 city will not be retained once XX2 city is set as a priority alert area.

[0052] The above application scenarios can be selected according to user needs and user operation instructions. Of course, it is also possible to directly designate the key alert areas for all earthquakes in a multi-earthquake scenario at once, and modify the prompt content to ask whether to designate City XX1 (the area where the epicenter of earthquake 1 is located), City XX2 (the area where the epicenter of earthquake 2 is located) ... City XXn (the area where the epicenter of earthquake n is located) as key alert areas.

[0053] In some embodiments provided by the present invention, the method further includes: acquiring a prompting mode and a prompting intensity, wherein the prompting mode includes at least one of a visual prompt, an audio prompt, and a vibration prompt, and the prompting intensity includes a strong prompt and a weak prompt; determining, based on the received seismic information of the second earthquake, a first comparison result of the epicentral distance of the current location from the epicenter of the second earthquake to a second preset distance range, a second comparison result of the magnitude of the second earthquake to a magnitude threshold in the target earthquake early warning threshold, and a third comparison result of the estimated intensity of the current location to an intensity threshold in the target earthquake early warning threshold; and selecting multiple combinations or one of the prompting modes and the prompting intensity to issue an early warning based on at least one of the first comparison result, the second comparison result, and the third comparison result.

[0054] Specifically, based on at least one of the prompting methods (visual prompts, sound prompts, and vibration prompts) and at least one of the prompting intensities (strong prompts and weak prompts), a corresponding prompting strategy is obtained from the seismic information of the second earthquake, among possible combinations of prompting methods and prompting intensities.

[0055] When determining the prompting method, the specific options include the following:

[0056] Option 1: Based on the first, second, and third comparison results, select one or more combinations of visual, audio, and vibration alerts for early warning. For example, when the epicentral distance is less than the minimum of the second preset distance range, the magnitude of the second earthquake is greater than the magnitude threshold, and the estimated intensity at the current location is greater than the intensity threshold, issue an early warning using simultaneous visual, audio, and vibration responses. When the epicentral distance is within the second preset distance range, the magnitude of the second earthquake is greater than the magnitude threshold, and the estimated intensity at the current location is less than the intensity threshold, only a visual response is issued, which can be a pop-up window or a visual alert. When the epicentral distance is within the second preset distance range, the magnitude of the second earthquake is less than the magnitude threshold, and the estimated intensity at the current location is greater than the intensity threshold, both visual and vibration responses are issued, with the visual response method being a pop-up window or a visual alert. Vibration can be indicated using short or long vibrations. When the epicentral distance is greater than the second preset distance range, the magnitude of the second earthquake is less than the magnitude threshold, and the estimated intensity at the current location is less than the intensity threshold, no alert is issued, and only early warning information is received.

[0057] Option 2: Based on two of the first comparison result, the second comparison result, and the third comparison result, select one or more combinations of visual prompts, sound prompts, and vibration prompts to issue a warning; it can be the first comparison result and the second comparison result, the first comparison result and the third comparison result, or the second comparison result and the third comparison result.

[0058] Based on the second and third comparison results, one or more combinations of visual, audio, and vibration alerts are selected for early warning. For example: when the magnitude of the second earthquake is greater than the magnitude threshold and the estimated intensity at the current location is greater than the intensity threshold, a simultaneous visual, audio, and vibration alert is issued; when the magnitude of the second earthquake is greater than the magnitude threshold and the estimated intensity at the current location is less than the intensity threshold, only a visual response is issued, which can be a pop-up window or a visual alert; when the magnitude of the second earthquake is less than the magnitude threshold and the estimated intensity at the current location is greater than the intensity threshold, both visual and vibration responses are issued, with the visual response appearing as a pop-up window or a visual alert; vibration alerts can be provided using short or long vibration patterns; when the magnitude of the second earthquake is less than the magnitude threshold and the estimated intensity at the current location is less than the intensity threshold, no alert is issued, and only early warning information is received.

[0059] Option 3: Based on any one of the first, second, and third comparison results, select one or more combinations of visual, audio, and vibration prompts to issue a warning; for example, if the estimated intensity of the current location is greater than the intensity threshold, issue a warning by responding with visual, audio, and vibration simultaneously; if the estimated intensity of the current location is less than the intensity threshold, do not issue a prompt, and only receive the warning information.

[0060] The specific methods included in determining the intensity of the warning are as follows:

[0061] Option 1: Based on the first, second, and third comparison results, select either a strong or weak warning method for early warning; for example, if the epicentral distance is less than the minimum value of the second preset distance range, the magnitude of the second earthquake is greater than the magnitude threshold, and the estimated intensity at the current location is greater than the intensity threshold, use a strong warning method; if the epicentral distance is within the second preset distance range, the magnitude of the second earthquake is greater than the magnitude threshold, and the estimated intensity at the current location is less than the intensity threshold, use a weak warning method; if the epicentral distance is within the second preset distance range, the magnitude of the second earthquake is less than the magnitude threshold, and the estimated intensity at the current location is less than the intensity threshold, no warning is issued.

[0062] Option 2: Based on two of the first, second, and third comparison results, select either a strong or weak warning to issue an alert; it could be the first and second comparison results, the first and third comparison results, or the second and third comparison results.

[0063] Based on the first and third comparison results, a warning is issued by selecting either a strong warning or a weak warning. For example, when the epicentral distance is less than the minimum value of the second preset distance range and the estimated intensity at the current location is greater than the intensity threshold, a strong warning is issued; when the epicentral distance is within the second preset distance range and the estimated intensity at the current location is greater than the intensity threshold, a weak warning is issued; and when the epicentral distance is greater than the maximum value of the second preset distance range and the estimated intensity at the current location is less than the intensity threshold, no warning is issued.

[0064] Based on the second and third comparison results, a warning is issued by selecting either a strong or weak warning. For example, if the magnitude of the second earthquake is greater than the magnitude threshold and the estimated intensity at the current location is greater than the intensity threshold, a strong warning is issued. If the magnitude of the second earthquake is greater than the magnitude threshold and the estimated intensity at the current location is less than the intensity threshold, a weak warning is issued. If the magnitude of the second earthquake is less than the magnitude threshold and the estimated intensity at the current location is less than the intensity threshold, no warning is issued.

[0065] Based on the first and second comparison results, a warning is issued by selecting either a strong or weak warning. For example, a strong warning is issued when the epicentral distance is less than the minimum value of the second preset distance range and the magnitude of the second earthquake is greater than the magnitude threshold; a weak warning is issued when the epicentral distance is within the second preset distance range and the magnitude of the second earthquake is greater than the magnitude threshold; and no warning is issued when the epicentral distance is greater than the maximum value of the second preset distance range and the magnitude of the second earthquake is less than the magnitude threshold. In other words, a strong warning is issued for major earthquakes that have a significant impact on the target area, or for major earthquakes that have a relatively minor impact on the target area but are located in the surrounding area; for example, a strong warning is issued when the epicentral distance is less than 100 km and the magnitude is greater than 6.0.

[0066] For large earthquakes occurring at a distance with minimal impact on the target area, and for small earthquakes occurring in the vicinity of the target area with minimal impact, a weak alert will be issued; for example, a weak alert will be issued when the epicentral distance is greater than 100km but less than 200km and the magnitude is greater than 6.0. For large earthquakes occurring at a distance exceeding the epicentral distance threshold, no alert will be issued; for example, earthquakes with an epicentral distance greater than 200km will not be alerted.

[0067] Option 3: Based on any one of the first, second, or third comparison results, select either a strong or weak alert for warning. For example, if the estimated intensity at the current location is greater than the intensity threshold, a strong alert is used; if the estimated intensity at the current location is less than the intensity threshold, a weak alert is used. The aforementioned strong and weak alerts vary depending on the type of warning terminal. For example, a strong alert on a mobile phone includes: a strong pop-up window (a pop-up window in the center of the screen) and temporarily stopping other applications, increasing the volume of the earthquake warning; simultaneously, intermittent short vibrations occur during the countdown, and a long vibration is used to alert the user when the seismic wave arrives; a weak alert on a mobile phone includes: a pop-up window in the center of the screen, without vibration or voice prompts, and the user can close the pop-up window during the warning process.

[0068] For example, on television: Strong alerts include a strong pop-up (a pop-up in the center of the screen), which lowers the volume of the television program and increases the sound of the earthquake warning; False alerts include a false pop-up (a small pop-up in the lower right corner), which identifies the current television volume. If the current volume is below 50%, it is raised to 50% before the warning is broadcast; if the current volume is above 50%, the warning is broadcast at the current volume. Users can also manually disable the warning.

[0069] In some embodiments of the present invention, the method further includes: if it is determined that the warning intensity of the user terminal is a strong warning, identifying the parameter value of the user terminal parameter at the current moment, wherein the user terminal parameter includes at least one of volume, brightness, and vibration; if the parameter value of the user terminal parameter is lower than a first preset percentage value of the maximum parameter value, increasing the parameter value of the user terminal parameter to the first preset percentage value of the maximum parameter value; if the parameter value of the user terminal parameter is higher than the first preset percentage value of the maximum parameter value, increasing the parameter value of the user terminal parameter by a second preset percentage value of the maximum parameter value based on the parameter value of the user terminal parameter, wherein the second preset percentage value is less than the first preset percentage value.

[0070] When the warning intensity of the user terminal is determined to be a strong warning, the warning method of the user terminal is determined according to the warning method. If the warning method includes a screen prompt, the brightness parameter of the user terminal is determined. The brightness value of the user terminal at the current moment is identified. If the brightness value is lower than a first preset percentage value of the maximum brightness value, wherein the first preset percentage value can be any percentage not less than 50%, the brightness value is increased to the first preset percentage value of the maximum brightness value. If the brightness value is higher than the first preset percentage value of the maximum brightness value, the second preset percentage value of the maximum brightness value is increased based on the brightness value at the current moment. The second preset percentage value is less than the first preset percentage value, wherein the second preset percentage value is any percentage less than 50%.

[0071] For example, when the user terminal is a mobile phone and the warning intensity is set to "strong," the system specifically identifies the phone's current volume. If the current volume is below 50%, the volume is increased to 50% before the earthquake warning is broadcast; if the current volume is above 50%, the volume is increased by three increments before the earthquake warning is broadcast. Similarly, when the user terminal is a television and the warning intensity is set to "strong," the system identifies the current volume. If the current volume is below 50%, the volume is increased to 50% before the warning is broadcast; if the current volume is above 50%, the volume is increased by three increments before the earthquake warning is broadcast. Three increments represent 30% of the maximum volume value.

[0072] When the warning intensity of the user terminal is determined to be a strong warning, the warning method of the user terminal is determined according to the warning method. If the warning method includes an audio warning, the user terminal parameter is determined to be volume. The volume value of the user terminal at the current moment is identified. If the volume value is lower than a first preset percentage value of the maximum volume value, wherein the first preset percentage value can be any percentage value not less than 50%, then the volume value is increased to the first preset percentage value of the maximum volume value. If the volume value is higher than the first preset percentage value of the maximum volume value, then the volume value at the current moment is increased by a second preset percentage value of the maximum volume value. The second preset percentage value is less than the first preset percentage value, wherein the second preset percentage value is any percentage less than 50%.

[0073] When the warning intensity of the user terminal is determined to be a strong warning, the warning method of the user terminal is determined according to the warning method. If the warning method includes vibration warning, the user terminal parameter is determined to be vibration warning. The vibration intensity of the user terminal at the current moment is identified. If the vibration intensity is lower than a first set percentage value of the maximum vibration intensity, wherein the first set percentage value can be any percentage value not less than 50%, the vibration intensity is increased to the first set percentage value of the maximum vibration intensity. If the vibration intensity is higher than the first set percentage value of the maximum vibration intensity, the second set percentage value of the maximum vibration intensity is increased based on the vibration intensity at the current moment. The second set percentage value is less than the first set percentage value, and the second set percentage value is any percentage less than 50%.

[0074] Therefore, the above embodiments provided by the present invention can set different earthquake early warning thresholds according to the user terminal's personalized settings, and use them to provide earthquake early warning, thus meeting the user's personalized needs.

[0075] Based on the same inventive concept, some embodiments of the present invention also provide an optimized disaster early warning device. Figure 2 This is a schematic diagram of the structure of an optimized disaster early warning device provided in one embodiment of the present invention. Figure 2As shown, the device includes: a first mapping module for acquiring the earthquake intensity rapid report result of a first earthquake, wherein the earthquake intensity rapid report result includes a first mapping relationship between geographical location and earthquake intensity; a second mapping module for determining a second mapping relationship between geographical location and earthquake early warning threshold based on the first mapping relationship and a preset mapping relationship between earthquake intensity and earthquake early warning threshold; and an early warning threshold determination module for determining the target earthquake early warning threshold corresponding to the current location based on the current location and the second mapping relationship.
