Description

Technical Field

[0001] The present application relates to the field of earthquake early warning technology, and in particular, to a testing method and program product for an earthquake early warning system. Background Art

[0002] Earthquake early warning is one of the most effective technical means to mitigate earthquake disasters. Based on dense observation stations and using data processing technology, earthquake early warning can issue earthquake wave warnings before destructive earthquake waves reach the target area, giving the public a few seconds to tens of seconds of precious time to escape and avoid danger. It can enable important projects and facilities such as nuclear power plants, high-speed railways, hazardous chemical companies, lifeline projects, and precision instrument manufacturing to take earthquake emergency response measures in a timely manner, thereby greatly reducing casualties and social property losses.

[0003] Earthquake early warning systems usually have functions such as earthquake monitoring data processing, early warning magnitude calculation, early warning positioning, early warning intensity estimation, and early warning information release. Users can learn about earthquake information through these functions and take appropriate risk avoidance measures when an earthquake occurs. However, once the earthquake early warning system makes mistakes or fails, such as false or missed earthquake early warning information, it may also cause relatively large economic losses and even threaten human life safety. Therefore, software testing for earthquake early warning systems is extremely important and necessary, and the requirements for the accuracy and real-time nature of earthquake early warning systems are also more stringent.

[0004] At present, there is no special software testing technology and testing process for the software testing of earthquake early warning systems. The relevant software testing of earthquake early warning systems has the technical problem of non-standard test data and cannot meet the testing requirements of earthquake early warning systems. Summary of the invention

[0005] In view of this, the purpose of the embodiments of the present application is to provide a testing method and program product for an earthquake early warning system to solve the above-mentioned technical problems.

[0006] In a first aspect, an embodiment of the present application provides a method for testing an earthquake early warning system, the method comprising:

[0007] Outputting test earthquake event data to an earthquake early warning system; wherein the test earthquake event data includes seismic wave data of different stations that vary with time;

[0008] Obtaining system warning data of an earthquake early warning system for the test earthquake event data;

[0009] The test result of the earthquake early warning system is determined according to the system early warning data and the expected early warning data of the test earthquake event data.

[0010] In the above implementation process, the test method of the earthquake early warning system includes: outputting test earthquake event data to the earthquake early warning system; wherein the test earthquake event data includes seismic wave data that varies with time at different stations; obtaining system warning data of the earthquake early warning system for the test earthquake event data; and determining the test result of the earthquake early warning system according to the system warning data and the expected warning data of the test earthquake event data. The test method outputs test earthquake event data including seismic wave data that varies with time at different stations to the earthquake early warning system; so as to simulate the operation and response of the earthquake early warning system to real earthquake events during the test process; and then more accurately determines the test result of the earthquake early warning system according to the system warning data and the expected warning data of the test earthquake event data. It is convenient for relevant personnel to adjust the earthquake early warning system according to the test results, and improve the accuracy and reliability of the earthquake early warning system. The technical problem that the test data of the relevant software test of the existing earthquake early warning system is not standardized is solved, and the test requirements of the earthquake early warning system can be met. In addition, the test method based on the above earthquake early warning system can help determine the warning time of the earthquake early warning system when an actual earthquake occurs; help evaluate the warning coverage of the earthquake early warning system, and identify the warning blind area.

[0011] Optionally, in an embodiment of the present application, the test seismic event data specifically includes seismic wave data of different stations at the same test time point.

[0012] In the above implementation process, since the test earthquake event data includes seismic wave data of different stations at the same test time point, the seismic wave data for testing can be output to the earthquake early warning system in sequence based on the test time point, thereby reducing the difficulty of data transmission and further reducing the difficulty of testing the earthquake early warning system.

[0013] Optionally, in an embodiment of the present application, the method for obtaining the test earthquake event data includes: obtaining real earthquake data based on historical earthquake events; when the real earthquake data includes the real station data of the station at a historical set time point, determining the real station data of the historical set time point as the seismic wave data of the station at the corresponding test time point; when the real earthquake data does not include the real station data of the station at the historical set time point, interpolating the real station data of the station at different historical time points to obtain the interpolated station data of the station at the historical set time point, and determining the interpolated station data of the historical set time point as the seismic wave data of the station at the corresponding test time point; wherein the time interval between two adjacent historical set time points is consistent with the time interval between two adjacent test time points.

[0014] In the above implementation process, real earthquake data is obtained based on historical earthquake events, and when the real earthquake data includes the real station data of the station at the historical set time point, the seismic wave data at the corresponding test time point is determined according to the real station data. By interpolating the real station data of the station at different historical time points when the real earthquake data does not include the real station data of the station at the historical set time point, the interpolated station data (fitting the real earthquake data) of the station at the historical set time point can be obtained. Based on the interpolated station data and the real earthquake data that fit the real earthquake data, the operation and response of the earthquake early warning system to the real earthquake event can be more realistically simulated during the test process, so as to further improve the effectiveness of the test results of the earthquake early warning system.

[0016] In the above implementation process, by adjusting the time parameters, station parameters, instrument parameters and / or seismic wave amplitude parameters of the seismic wave data corresponding to some stations in the test seismic event data, the adjusted test seismic event data that meets the actual test requirements (for example, boundary case testing) can be obtained; based on the adjusted test seismic event data, the early warning performance test of the earthquake early warning system can be more comprehensively implemented. In addition, by adjusting the time parameters, station parameters, instrument parameters and / or seismic wave amplitude parameters of the seismic wave data corresponding to some stations in the test seismic event data, some interference data can be added to the adjusted test seismic event data to improve the reliability of the test results of the earthquake early warning system; it is convenient to find and repair system problems early and reduce the cost of later maintenance.

[0018] In the above implementation process, the real-time data stream service can be used to convert the test earthquake event data into a simulated real-time earthquake data stream; and based on the simulated real-time earthquake data stream, the occurrence of a real earthquake event can be simulated; thus, the operation and response of the simulated earthquake early warning system to a real earthquake event can be realized during the test. In addition, the use of real-time data stream services can improve the stability and speed of data transmission, reduce the impact of data transmission efficiency on test results, and provide protection for the test process.

[0019] Optionally, in an embodiment of the present application, the system warning data includes warning data of multiple warning times corresponding to the test earthquake event data; determining the test result of the earthquake warning system based on the system warning data and the expected warning data of the test earthquake event data includes: determining the test result of the earthquake warning system based on the warning data of each warning time, the warning weight corresponding to each warning time and the expected warning data.

[0020] In the above implementation process, the requirements of earthquake for the timeliness of warning are fully taken into consideration. By using the warning data of each warning alert, the warning weight corresponding to each warning alert, and the expected warning data, the warning performance of the earthquake early warning system can be determined more accurately.

[0021] Optionally, in an embodiment of the present application, the test result includes an early warning accuracy index; the test result of the earthquake early warning system is determined based on the system early warning data and the expected early warning data of the test earthquake event data, including: determining the early warning information false alarm rate of the earthquake early warning system based on the number of false warning cases and the expected number of warning cases of the earthquake early warning system; and / or determining the early warning information omission rate of the earthquake early warning system based on the number of effective warning cases and the expected number of warning cases of the earthquake early warning system; and / or determining the early warning magnitude deviation of the earthquake early warning system based on the system early warning magnitude and the expected warning magnitude of the earthquake early warning system; And / or determine the warning positioning deviation of the earthquake early warning system based on the earthquake warning positioning and the expected warning positioning of the earthquake early warning system; and / or determine the intensity prediction deviation of the earthquake early warning system based on the system predicted intensity and the expected predicted intensity of the earthquake early warning system; and / or determine the warning earthquake occurrence time deviation of the earthquake early warning system based on the system warning earthquake occurrence time and the expected warning earthquake occurrence time of the earthquake early warning system; determine the warning accuracy index based on the warning information false alarm rate, the warning information omission rate, the warning magnitude deviation, the warning positioning deviation, the intensity prediction deviation and / or the warning earthquake occurrence time deviation.

[0036] The following embodiments of the technical solution of the present application are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present application, and are therefore only used as examples, and cannot be used to limit the scope of protection of the present application.

[0037] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by technicians in the technical field to which this application belongs; the terms used herein are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0038] In the description of the embodiments of the present application, the technical terms "first", "second", etc. are only used to distinguish different objects, and cannot be understood as indicating or implying relative importance or implicitly indicating the number, specific order or primary and secondary relationship of the indicated technical features. In the description of the embodiments of the present application, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0039] See also Figure 1 The flowchart of a method for testing an earthquake early warning system provided by an embodiment of the present application is shown. The method for testing an earthquake early warning system may include the following steps:

[0040] S101, outputting test earthquake event data to an earthquake early warning system; wherein the test earthquake event data includes seismic wave data of different stations that vary with time;

[0041] S102, obtaining system warning data of an earthquake early warning system for the test earthquake event data;

[0042] S103: Determine the test result of the earthquake early warning system according to the system early warning data and the expected early warning data of the test earthquake event data.

[0043] Among them, in step S101, the software test of the earthquake early warning system can be implemented based on the preset test case. Each test case may include multiple test earthquake cases, and each test earthquake case may be a set of test earthquake event data. The test earthquake event data may include earthquake waveform data that changes continuously over time at different stations; it may also include earthquake wave data at different stations at multiple test time points. By outputting earthquake wave data that changes over time to different stations, the operation and response of the earthquake early warning system to real earthquake events can be simulated during the test process.

[0044] In step S102, the system warning data may include: system warning magnitude, system warning location, system warning intensity or system warning earthquake occurrence time, etc. The system warning data corresponding to different earthquake warning systems may be different.

[0045] Among them, in step S103, the expected warning data may include the expected warning magnitude, the expected warning location, the expected warning intensity or the expected warning earthquake time, etc. Exemplarily, the test result of the warning magnitude may be determined according to the difference between the system warning magnitude and the expected warning magnitude; the test result of the warning location may be determined according to the distance between the system warning location and the expected warning location.

[0046] It can be seen from this that the test method of the earthquake early warning system provided by the embodiment of the present application can be output to the earthquake early warning system including the test earthquake event data of the seismic wave data that varies over time at different stations; to simulate the operation and response of the earthquake early warning system to the real earthquake event during the test. Then, according to the expected warning data of the system early warning data and the test earthquake event data, the test result of the earthquake early warning system is more accurately determined. It is convenient for relevant personnel to adjust the earthquake early warning system according to the test results, and the accuracy and reliability of the earthquake early warning system are improved. The technical problem that the relevant software test of the existing earthquake early warning system has irregular test data is solved, and the test requirements for the earthquake early warning system can be met.

[0047] In some optional embodiments, the test seismic event data specifically includes seismic wave data of different stations at the same test time point.

[0048] Among them, the test time points may include: a starting test time point, multiple intermediate test time points and an ending test time point. The test time intervals between multiple intermediate test time points, the test time intervals between the starting test time point and adjacent intermediate test time points, and the test time intervals between the ending test time point and adjacent intermediate test time points may be equal. And the specific test time intervals and the data of the test time points may be adjusted according to actual test requirements. Since the test earthquake event data includes the seismic wave data of different stations at the same test time point, the seismic wave data for testing can be output to the earthquake early warning system in sequence based on the test time points, which reduces the difficulty of data transmission, thereby reducing the difficulty of testing the earthquake early warning system.

[0049] Please refer to Figure 2 , Figure 2 A schematic diagram of the flow of a method for acquiring test earthquake event data provided in an embodiment of the present application.

[0050] In some optional embodiments, the method for obtaining the test earthquake event data includes: S201, obtaining real earthquake data based on historical earthquake events; S202, when the real earthquake data includes the real station data of the station at the historical set time point, determining the real station data of the historical set time point as the seismic wave data of the station at the corresponding test time point; S203, when the real earthquake data does not include the real station data of the station at the historical set time point, interpolating the real station data of the station at different historical time points to obtain the interpolated station data of the station at the historical set time point, and determining the interpolated station data of the historical set time point as the seismic wave data of the station at the corresponding test time point; wherein the time interval between two adjacent historical set time points is consistent with the time interval between two adjacent test time points.

[0051] Among them, as described above, a test earthquake case can be constructed based on the real earthquake data obtained from the historical earthquake event, and each test earthquake case can include a set of test earthquake event data. In the case where the test earthquake event data includes seismic wave data of different stations at the same test time point, the seismic wave data can be output to different stations in sequence according to the set test time point to achieve the backtracking of the real earthquake case (that is, the playback of historical earthquake data), so as to obtain the software test results of the earthquake early warning system more accurately based on the system early warning data of the earthquake early warning system in the process of earthquake case backtracking. The seismic wave data in the test process of the earthquake early warning system can be determined according to the real seismic data of a single historical earthquake event; the seismic wave data in the test process of the earthquake early warning system can also be determined according to the superposition data of the real seismic data of multiple historical earthquake events. The real station data of the station at different historical time points can be interpolated based on the interpolation algorithm (for example, a linear interpolation algorithm or a polynomial interpolation algorithm) to obtain the interpolated station data of the station at the historical set time point. The interpolated station data of the station at the historical set time point can also be obtained based on the least squares method, polynomial fitting or curve fitting. By acquiring real earthquake data based on historical earthquake events, and in the case where the real earthquake data includes the real station data of the station at the historical set time point, the seismic wave data at the corresponding test time point is determined according to the real station data. By interpolating the real station data of the station at different historical time points when the real earthquake data does not include the real station data of the station at the historical set time point, the interpolated station data (fitting the real earthquake data) of the station at the historical set time point can be obtained. Based on the interpolated station data and the real earthquake data that fit the real earthquake data, the operation and response of the earthquake early warning system to the real earthquake event can be more realistically simulated during the test process, so as to further improve the effectiveness of the test results of the earthquake early warning system.

[0052] In some optional embodiments, before outputting the test earthquake event data to the earthquake early warning system, the method further includes: adjusting, according to test requirements, time parameters, station parameters, instrument parameters and / or seismic wave amplitude parameters of the seismic wave data corresponding to some stations in the test earthquake event data to obtain adjusted test earthquake event data; outputting the test earthquake event data to the earthquake early warning system includes: outputting the adjusted test earthquake event data to the earthquake early warning system.

[0053] Among them, adjusting the time parameters of the seismic wave data corresponding to some stations can change the time interval between historical earthquake events, and adjust the historical earthquake events occurring at different times to occur at adjacent times or at the same time; adjusting the station parameters of the seismic wave data corresponding to some stations can change the parameters such as the epicenter position and earthquake direction of the historical earthquake events; adjusting the seismic wave amplitude parameters of the seismic wave data corresponding to some stations can change the parameters such as the magnitude and intensity of the historical earthquake events; adjusting the instrument parameters of the seismic wave data corresponding to some stations can change the parameters such as the sensitivity or response time of some instruments of the corresponding stations. It is also possible to obtain more abundant test earthquake cases by adjusting the relevant parameters of the simulated earthquake event (the earthquake event obtained by adjusting the relevant parameters of the historical earthquake event). By adjusting the time parameters, station parameters, instrument parameters and / or seismic wave amplitude parameters of the seismic wave data corresponding to some stations in the test earthquake event data, test earthquake cases in various regions or times can be artificially constructed; and then based on the constructed test earthquake cases, the early warning performance test of the earthquake early warning system is more fully and comprehensively realized.

[0054] Among them, the time alignment between different earthquake events can be achieved based on the time of the earthquake event, and the test earthquake cases of some special scenarios can be constructed by using methods such as waveform translation, waveform superposition, waveform combination and waveform deletion; for example, special earthquake cases such as double earthquakes in different places, multiple earthquakes in different places, foreshocks and foreshocks. By adjusting the seismic wave data time parameters, station parameters, instrument parameters or seismic wave amplitude parameters corresponding to some stations, the station distribution of any earthquake, the event distribution of the earthquake, the event size of the earthquake and the earthquake events of different focal mechanisms can be set, and then the early warning speed and intensity prediction accuracy of the system can be better tested based on the test earthquake case. Processing capabilities such as. Exemplarily, taking the earthquake events of locations A and B with different earthquake occurrence times as an example, the earthquake event file (earthquake event file A at location A and earthquake event file B at location B) including real earthquake data can be obtained according to historical earthquake events, and the earthquake test earthquake case at location A and the earthquake test earthquake case at location B are generated based on the earthquake event files A and B respectively; and then a new test earthquake case is generated by waveform superposition. Specifically, the earthquake event file of location A within a certain time period (which can be 120s, 100s, 180s or other reasonable values) can be intercepted first, and the intercepted event file can be moved from the earthquake occurrence time of the earthquake event at location A to the earthquake occurrence time of the earthquake at location B. Based on the superimposed test earthquake case, the test earthquake event data is output to different stations, and the test results of the earthquake early warning system are determined based on the system early warning data and the expected early warning data. Taking the earthquake occurrence time of the earthquake event at location B as t1 as an example, the test results of the earthquake early warning system can be determined based on the early warning data of the superimposed test earthquake case by the earthquake early warning system (specifically, the test results of the earthquake early warning system can be evaluated from aspects such as whether it is possible to warn of two earthquakes, the early warning time of the two earthquakes, and the prediction of the occurrence time of the two earthquakes).

[0055] In some optional embodiments, S101, outputting test earthquake event data to an earthquake early warning system, includes: utilizing a real-time data stream service to convert the test earthquake event data into a simulated real-time earthquake data stream; and outputting the simulated real-time earthquake data stream to the earthquake early warning system.

[0056] Among them, the streaming media server can be used to store and manage the constructed test earthquake cases (including at least one set of test earthquake event data), and the real-time data stream service can be used to output the test earthquake event data to different stations. The real-time data stream service can be used to convert the test earthquake event data into a simulated real-time earthquake data stream; and based on the simulated real-time earthquake data stream, the occurrence of real earthquake events can be simulated; thereby realizing the operation and response of the earthquake early warning system to real earthquake events during the test. In addition, the use of real-time data stream services can improve the stability and speed of data transmission, reduce the impact of data transmission efficiency on test results, and provide protection for the test process. Please refer to Figure 3, Figure 3 A schematic diagram of an earthquake case backtracking process provided for an embodiment of the present application. Test earthquake cases constructed based on historical earthquake events can be stored in an earthquake case database, and the required test earthquake cases can be queried and downloaded from the earthquake case database according to actual test requirements; earthquake case identification is performed on the downloaded required test earthquake cases, and at least one playback earthquake case file is generated. The test parameters can also be configured in the parameter configuration interface to obtain a test strategy file, and the time-varying seismic wave data of different stations included in the test earthquake case file can be converted into a real-time data stream based on the relevant tools of the stream service. And based on the original test data obtained by the test earthquake case conversion, or based on time shift, waveform superposition, waveform combination or waveform deletion (adjusting the time parameters, station parameters, instrument parameters and / or seismic wave amplitude parameters corresponding to the seismic wave data), the earthquake early warning system is tested.

[0057] In some optional embodiments, the system warning data includes warning data of multiple warning times corresponding to the test earthquake event data; and determining the test result of the earthquake warning system based on the system warning data and the expected warning data of the test earthquake event data includes: determining the test result of the earthquake warning system based on the warning data of each warning time, the warning weight corresponding to each warning time and the expected warning data.

[0058] Among them, the system warning data may include primary warning data and secondary warning data; in this case, the warning weight corresponding to the primary warning data may be 0.7, and the warning weight corresponding to the secondary warning data may be 0.3. The system warning data may also include primary warning data, secondary warning data, and tertiary warning data; in this case, the warning weight corresponding to the primary warning data may be 0.55, the warning weight corresponding to the secondary warning data may be 0.35, and the warning weight corresponding to the tertiary warning data may be 0.1. The effective warning times and the warning weights of different warning times can be adjusted according to actual conditions. By fully considering the requirements of earthquakes for warning timeliness, and based on the warning data of each warning time, the warning weight corresponding to each warning time, and the expected warning data, the warning performance of the earthquake early warning system can be more accurately determined.

[0059] In some optional embodiments, the test result includes an early warning accuracy index; the test result of the earthquake early warning system is determined based on the system early warning data and the expected early warning data of the test earthquake event data, including: determining the early warning information false alarm rate of the earthquake early warning system based on the number of false warning cases and the expected number of warning cases of the earthquake early warning system; and / or determining the early warning information omission rate of the earthquake early warning system based on the number of effective warning cases and the expected number of warning cases of the earthquake early warning system; and / or determining the early warning magnitude deviation of the earthquake early warning system based on the system warning magnitude and the expected warning magnitude of the earthquake early warning system; and / or determine the warning positioning deviation of the earthquake early warning system based on the earthquake warning positioning and the expected warning positioning of the earthquake early warning system; and / or determine the intensity prediction deviation of the earthquake early warning system based on the system predicted intensity and the expected predicted intensity of the earthquake early warning system; and / or determine the warning earthquake occurrence time deviation of the earthquake early warning system based on the system warning earthquake occurrence time and the expected warning earthquake occurrence time of the earthquake early warning system; determine the warning accuracy index based on the warning information false alarm rate, the warning information omission rate, the warning magnitude deviation, the warning positioning deviation, the intensity prediction deviation and / or the warning earthquake occurrence time deviation.

According to the system warning earthquake time ΔT eew , Expected warning earthquake time ΔT ag and ΔT error =ΔT eew -ΔT ag , determine the deviation of the warning earthquake time ΔT error The test result of the earthquake early warning system's early warning accuracy index can be comprehensively determined based on the early warning information false alarm rate, early warning information omission rate, early warning magnitude deviation, early warning location deviation, intensity prediction deviation and / or early warning earthquake occurrence time deviation. Determine the evaluation end time T of the earthquake early warning system's early warning accuracy index end ; When the test earthquake is an earthquake within the network, E is 0; when the test earthquake is not an earthquake within the network, E is equal to the travel time of the first triggering station; M ag represents the expected warning magnitude. For example, the false alarm rate F of the warning information can be error ≠0 or the warning information underreporting rate I error When the accuracy is ≥15%, the earthquake early warning system is considered to have a warning accuracy of 0.

[0068] Table 1 Comprehensive test results corresponding to different values ​​of early warning performance indicators

[0069] As shown in Table 1, when the value of the comprehensive test index (or functional completeness index / early warning accuracy index / early warning timeliness index) of the earthquake early warning system is in the numerical interval of [0.95, 1.0], the comprehensive test result of the earthquake early warning system is determined to be excellent. When the value of the comprehensive test index (or functional completeness index / early warning accuracy index / early warning timeliness index) of the earthquake early warning system is in the numerical interval of [0.90, 0.95), the comprehensive test result of the earthquake early warning system is determined to be good. When the value of the comprehensive test index (or functional completeness index / early warning accuracy index / early warning timeliness index) of the earthquake early warning system is in the numerical interval of [0.85, 0.90), the comprehensive test result of the earthquake early warning system is determined to be qualified. When the value of the comprehensive test index (or functional completeness index / early warning accuracy index / early warning timeliness index) of the earthquake early warning system is in the numerical interval of [0, 0.85), the comprehensive test result of the earthquake early warning system is determined to be poor.

[0070] In an optional embodiment, it is also possible to V3=RT , respectively determine the early warning accuracy index V2 and the early warning timeliness index V3.

[0071] For example, when the system early warning data includes early warning data of a plurality of early warning times corresponding to the test earthquake event data, the system early warning data may be based on Calculate the measurement value corresponding to the warning positioning deviation; where W i represents the weight value corresponding to the i-th early warning, L n Indicates the warning location deviation corresponding to the nth warning. Calculate the measured value R corresponding to the warning magnitude deviation M ; Among them, M errorn It indicates the warning magnitude deviation corresponding to the nth warning. Calculate the measured value corresponding to the intensity prediction deviation; where δ errorn It represents the intensity prediction deviation corresponding to the nth warning. Calculate the measured value corresponding to the deviation of the warning earthquake time; where ΔT errorn It indicates the deviation of the warning earthquake time corresponding to the nth warning. Calculate the measured value corresponding to the warning timeliness deviation; where T errorn It represents the warning timeliness deviation corresponding to the nth warning. By fully considering the requirements of earthquake on warning timeliness, and according to the warning data of each warning, the warning weight corresponding to each warning, and the expected warning data, the warning performance of the earthquake early warning system can be determined more accurately. Table 2 shows the warning weight corresponding to one of the different warning times.
