[0046] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0047] It should be noted that the user information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data for display, data for analysis, etc.) involved in this application are all information and data authorized by the user or fully authorized by all parties; correspondingly, this application also provides a corresponding user authorization entrance for users to choose to authorize or refuse.

[0048] In one embodiment, Figure 1 As shown, a method for monitoring earthquake damage of a pillar insulator is provided. This embodiment uses the method applied to a terminal as an example for illustration. It can be understood that the method can also be applied to a server, and can also be applied to a system including a terminal and a server, and is implemented through the interaction between the terminal and the server. In this embodiment, the method includes the following steps:

[0049] Step 101, obtaining initial acceleration data of the post insulator collected under earthquake action; the initial acceleration data includes a plurality of characteristic acceleration sets corresponding to each time point in a target time period; the acceleration values ​​in each characteristic acceleration set have the same coordinate axis component information;

[0050] Among them, the target time period can be a specified monitoring time period under the action of an earthquake. For example, 0-45 seconds under the action of an earthquake can be preset as the monitoring time period, and the collected 0-45 seconds acceleration data can be used as initial acceleration data for data analysis. The monitoring time period can be determined through preliminary experiments.

[0051] As an example, the characteristic acceleration set may be acceleration data corresponding to the same coordinate axis component information, such as each time point may have acceleration data corresponding to the X-axis, acceleration data corresponding to the Y-axis, and acceleration data corresponding to the Z-axis.

[0052] In practical applications, the response of the post insulators can be monitored under actual earthquake action by acquiring the initial acceleration data of the post insulators collected under the earthquake action. The initial acceleration data can include multiple characteristic acceleration sets corresponding to each time point in the target time period, and the acceleration values ​​in each characteristic acceleration set have the same coordinate axis component information.

[0053] For example, under the action of a near-field earthquake, acceleration recording data (i.e., initial acceleration data) collected by a preset acceleration sensor can be obtained. The preset acceleration sensor can be a three-axis acceleration sensor, and the collected acceleration recording data can be expressed in the following manner:

[0054]

[0055] Among them, X it , Y it , Z it , i=1, ...10, which can respectively represent the acceleration data collected by each triaxial acceleration sensor at time t under the action of an earthquake. For example, when time t is 45 seconds, the data collected by triaxial acceleration sensor 1 are X1, Y1, and Z1.

[0056] In one example, the following may be used: Figure 2 The monitoring device shown is used to monitor and assess the damage of post insulators under actual earthquake action. Figure 2 1 is a sensor, which may include a plurality of preset acceleration sensors, such as a three-axis acceleration sensor, Figure 2 2 is an acquisition card, which can transmit the collected sensor data to the industrial computer 3. Figure 2 3 is an industrial computer, which can be used to analyze and calculate the initial acceleration data collected under the action of earthquake. Figure 2 4 is a UPS (Uninterruptible Power Supply) unit with a battery.

[0057] Step 102, for each time point, respectively determine the first characteristic acceleration value from each characteristic acceleration set corresponding to the time point, and obtain a plurality of first characteristic acceleration values ​​corresponding to the time point;

[0058] After obtaining the initial acceleration data, for each time point, each characteristic acceleration set corresponding to the time point can be sorted by absolute value, and the first characteristic acceleration value can be determined from each characteristic acceleration set. Then, the first characteristic acceleration value corresponding to each characteristic acceleration set can be used as multiple first characteristic acceleration values ​​corresponding to the time point.

[0059] Specifically, the acceleration data corresponding to the X-axis, the acceleration data corresponding to the Y-axis, and the acceleration data corresponding to the Z-axis at the same time can be sorted by absolute values, and the maximum absolute value can be selected, while the original positive and negative signs of the maximum absolute value can be retained, thereby obtaining the following data:

[0060]

[0061] Among them, X re , Y re , Z re (i.e., multiple first characteristic acceleration values) are respectively the maximum absolute values ​​selected at time t. For example, when time t is 45 seconds, the acceleration data corresponding to the X-axis (i.e., the characteristic acceleration set) are sorted by absolute values, and the maximum absolute value 1.53E-1 (i.e., the first characteristic acceleration value) can be obtained.

[0062] Step 103, amplifying the multiple first characteristic acceleration values ​​corresponding to each of the time points according to a preset amplification coefficient table, to obtain multiple second characteristic acceleration values ​​corresponding to each of the time points;

[0063] In a specific implementation, a preset amplification factor table can be obtained. Based on the preset specified amplification factors for each first characteristic acceleration value corresponding to different time points in the amplification factor table, the multiple first characteristic acceleration values ​​corresponding to each time point can be amplified respectively, and then the multiple second characteristic acceleration values ​​corresponding to each time point can be obtained.

[0064] For example, when time t is 45 seconds, X re Corresponding to the preset magnification factor a, Y re Corresponding to the preset magnification factor b, Z re There is a preset magnification factor c, which can be calculated based on the magnification factor a and X re , we get X when time t is 45 seconds re-new , or according to the magnification factor b and Y re , we get Y when time t is 45 seconds re-new, or according to the magnification coefficients c and Z re , we get Z at time t of 45 seconds re-new , X re-new , Y re-new , Z re-new That is, the multiple second characteristic acceleration values ​​corresponding to the time t (ie, the time point) being 45 seconds.

[0065] Step 104, constructing a plurality of acceleration response spectra based on the plurality of second characteristic acceleration values ​​corresponding to each of the time points and the preset reference spectrum lines, and determining the seismic damage of the post insulator according to the spectrum line comparison results of each of the acceleration response spectra; each acceleration response spectrum corresponds to specified coordinate axis component information.

[0066] Among them, the multiple acceleration response spectra may include an X-axis acceleration response spectrum, a Y-axis acceleration response spectrum, and a Z-axis acceleration response spectrum. Each acceleration response spectrum may have a design spectrum (i.e., a preset reference spectrum line) and a response spectrum obtained according to the second characteristic acceleration value corresponding to each time point.

[0067] In practical applications, according to the multiple second characteristic acceleration values ​​corresponding to each time point and the specified coordinate axis component information, the response spectra corresponding to different coordinate axis components can be obtained, such as the response spectrum in the X-axis acceleration response spectrum, the response spectrum of the Y-axis acceleration response spectrum, and the response spectrum of the Z-axis acceleration response spectrum. Then, based on the preset reference spectrum line, such as the design spectrum, multiple acceleration response spectra can be constructed, and then the seismic damage of the post insulator can be determined according to the spectrum line comparison results of each acceleration response spectrum.

[0068] Specifically, the spectral line comparison results of the design spectrum and the response spectrum in the X-, Y-, and Z-axis acceleration response spectra can characterize whether the post insulator is damaged under the earthquake. When the spectral line comparison results of the X-, Y-, and Z-axis acceleration response spectra are all undamaged, it can be determined that the post insulator is not damaged under the earthquake.

[0069] In the above-mentioned post insulator earthquake damage monitoring method, by obtaining the initial acceleration data of the post insulator collected under the action of an earthquake, and then for each time point, respectively determining the first characteristic acceleration value from each characteristic acceleration set corresponding to the time point, obtaining multiple first characteristic acceleration values ​​corresponding to the time point, and amplifying the multiple first characteristic acceleration values ​​corresponding to each time point according to a preset amplification coefficient table, respectively obtaining multiple second characteristic acceleration values ​​corresponding to each time point, and then constructing multiple acceleration response spectra based on the multiple second characteristic acceleration values ​​corresponding to each time point and the preset reference spectrum line, and determining the earthquake damage of the post insulator according to the spectrum line comparison results of each acceleration response spectrum, thereby realizing the monitoring and damage assessment of the post insulator under the actual earthquake action, and evaluating the damage of the post insulator according to the collected triaxial acceleration data by monitoring the response of the post insulator under the earthquake action, which can be applied to the DC converter station in the earthquake zone, and improve the safe operation level of the converter station.

[0070] In one embodiment, the obtaining of the initial acceleration data of the post insulator collected under earthquake action may include the following steps:

[0071] Determine a target time period under earthquake action; obtain initial acceleration data of the post insulator collected under earthquake action according to the target time period; the initial acceleration data is collected by a plurality of preset acceleration sensors arranged at the bottom of the post insulator.

[0072] In practical applications, the target time period can be determined according to the specified monitoring time period under the action of an earthquake, and then based on the target time period, the initial acceleration data of the post insulator collected under the action of an earthquake can be obtained by configuring a plurality of preset acceleration sensors at the bottom of the post insulator. For example, the target time period can be 0-45 seconds under the action of an earthquake, or it can be preset to other time periods, which is not specifically limited in this embodiment.

[0073] In one example, the post insulator to be monitored is 12278 mm long and is a composite insulator. Multiple triaxial acceleration sensors can be installed at equal distances at the bottom of the post insulator to collect initial acceleration data under earthquake action, such as arranging 10 triaxial acceleration sensors at equal distances in a ring at the bottom of the post insulator.

[0074] In this embodiment, by determining the target time period under the action of the earthquake, and then obtaining the initial acceleration data of the post insulator collected under the action of the earthquake based on the target time period, the collected initial acceleration data can be obtained according to the specified monitoring time period under the action of the earthquake, thereby providing data support for the subsequent damage assessment of the post insulator.

[0075] In one embodiment, for each time point, determining the first characteristic acceleration value from each characteristic acceleration set corresponding to the time point, and obtaining multiple first characteristic acceleration values ​​corresponding to the time point may include the following steps:

[0076] For each time point, the characteristic acceleration sets corresponding to the time point are sorted by absolute value, and the maximum absolute value in the characteristic acceleration sets is used as the first characteristic acceleration value; and multiple first characteristic acceleration values ​​corresponding to the time point are determined.

[0077] In practical applications, for each time point in the initial acceleration data, the characteristic acceleration sets corresponding to the time point can be sorted by absolute value, and the maximum absolute value in each characteristic acceleration set can be used as the first characteristic acceleration value, and then multiple first characteristic acceleration values ​​corresponding to each time point can be obtained. For example, each time t can correspond to X re , Y re , Z re , and can retain X re , Y re , Z re The original sign of .

[0078] In this embodiment, by sorting the characteristic acceleration sets corresponding to each time point by absolute value, taking the maximum absolute value in each characteristic acceleration set as the first characteristic acceleration value, and then determining multiple first characteristic acceleration values ​​corresponding to the time point, the initial acceleration data can be preliminarily processed, and the maximum absolute value can be selected based on absolute value sorting, providing data support for further data analysis.

[0079] In one embodiment, the time points may include integer time points, and the amplification process is performed on the multiple first characteristic acceleration values ​​corresponding to each of the time points according to a preset amplification coefficient table to obtain the multiple second characteristic acceleration values ​​corresponding to each of the time points, which may include the following steps:

[0080] According to the multiple first characteristic acceleration values ​​corresponding to the integer time points, a target amplification factor table is determined from multiple preset amplification factor tables; each amplification factor table has a matching first characteristic acceleration value; the amplification factor table includes multiple specified amplification factors corresponding to each of the integer time points; based on the target amplification factor table, the multiple first characteristic acceleration values ​​corresponding to each of the time points are amplified respectively to obtain multiple second characteristic acceleration values ​​corresponding to each of the time points.

[0081] In practical applications, the time points may include integer time points. By obtaining multiple preset amplification factor tables, since each amplification factor table has a matching first characteristic acceleration value, a target amplification factor table can be determined from multiple preset amplification factor tables based on the multiple first characteristic acceleration values ​​corresponding to the integer time points. Then, based on the target amplification factor table, the multiple first characteristic acceleration values ​​corresponding to each time point can be amplified respectively to obtain multiple second characteristic acceleration values ​​corresponding to each time point.

[0082] In one example, according to X re Match the target magnification coefficient table, by obtaining the X corresponding to each time point re , Y re , Z re Then, based on the X corresponding to the integer time point re , in X re When the preset matching conditions in Table 2 are met, Table 2 can be determined as a target magnification coefficient table, and Table 2 can be expressed as follows:

[0083]

[0084]

[0085] Among them, max|x re |∈[0.1, 0.15) is the preset matching condition in Table 2, Ka, b, c are the preset specified magnification coefficients corresponding to each integer time point, such as K1-a is the X corresponding to integer time point 1 re The specified magnification factor, K1-b is the Y corresponding to the integer time point 1 re The specified magnification factor, K1-c is the Z corresponding to the integer time point 1 re The specified magnification factor is calculated by re , Y re , Z re Multiply by K iN , i=1, 2, …, 45, N=a, b, c, data amplification processing can be performed.

[0086] In this embodiment, a target amplification factor table is determined from multiple preset amplification factor tables based on multiple first characteristic acceleration values ​​corresponding to integer time points, and then based on the target amplification factor table, multiple first characteristic acceleration values ​​corresponding to each time point are amplified respectively to obtain multiple second characteristic acceleration values ​​corresponding to each time point. The target amplification factor table can be matched based on the first characteristic acceleration values ​​corresponding to the integer time points, so that the corresponding amplification factors can be accurately obtained.

[0087] In one embodiment, the time points may include non-integer time points, and the amplifying process is performed on the multiple first characteristic acceleration values ​​corresponding to each of the time points based on the target amplification coefficient table to obtain the multiple second characteristic acceleration values ​​corresponding to each of the time points, which may include the following steps:

[0088] For each integer time point, amplifying the multiple first characteristic acceleration values ​​corresponding to the integer time point according to the multiple specified amplification coefficients, to obtain multiple second characteristic acceleration values ​​corresponding to the integer time point;

[0089] In one example, as shown in Table 2, X of each integer second (ie, integer time point) may be re , Y re , Z re (i.e., multiple first characteristic acceleration values) are multiplied by K iN (i.e., multiple specified magnification factors), i = 1, 2, ..., 45, N = a, b, c, through data magnification processing, we can get the X of each integer second re-new , Y re-new , Z re-new (ie, multiple second characteristic acceleration values).

[0090] For each non-integer time point, a target integer time point corresponding to the non-integer time point is determined; and according to a plurality of specified amplification coefficients corresponding to the target integer time point, a plurality of first characteristic acceleration values ​​corresponding to the non-integer time point are amplified respectively to obtain a plurality of second characteristic acceleration values ​​corresponding to the non-integer time point.

[0091] In one example, when time t is a non-integer time point, such as non-integer time points 0.02 and 0.04 within 0-1 seconds, the integer second 1 can be used as the target integer time point corresponding to the non-integer time point within 0-1 seconds, and then the X corresponding to the non-integer time point within 0-1 seconds can be magnified according to the multiple specified magnification factors corresponding to the integer second 1. re , Y re , Z re Amplify the data to get the value of X for each non-integer second. re-new , Y re-new , Z re-new (ie, multiple second characteristic acceleration values).

[0092] For example, the multiple second characteristic acceleration values ​​corresponding to each time point may be represented in the following manner:

[0093]

[0094] In this embodiment, for each integer time point, according to multiple specified amplification coefficients, multiple first characteristic acceleration values ​​corresponding to the integer time point are respectively amplified to obtain multiple second characteristic acceleration values ​​corresponding to the integer time point, and for each non-integer time point, the target integer time point corresponding to the non-integer time point is determined, and then according to multiple specified amplification coefficients corresponding to the target integer time point, multiple first characteristic acceleration values ​​corresponding to the non-integer time point are respectively amplified to obtain multiple second characteristic acceleration values ​​corresponding to the non-integer time point. Based on a conforming amplification coefficient table, the first characteristic acceleration values ​​corresponding to the integer time point and the non-integer time point can be amplified using the specified amplification coefficient, thereby providing data support for constructing an acceleration response spectrum.

[0095] In one embodiment, determining the earthquake damage of the post insulator according to the spectral line comparison results of each acceleration response spectrum may include the following steps:

[0096] For each acceleration response spectrum, based on the spectrum line comparison result at the target position in the acceleration response spectrum, damage assessment information corresponding to the acceleration response spectrum is determined; and according to the damage assessment information corresponding to each acceleration response spectrum, the seismic damage condition of the post insulator is determined.

[0097] As an example, the target position may be a horizontal position in the acceleration response spectrum, that is, damage assessment information corresponding to the acceleration response spectrum may be determined based on the comparison results of the spectrum lines at the horizontal position in the acceleration response spectrum, such as whether the post insulator is damaged under the action of an earthquake.

[0098] In practical applications, for the X-axis acceleration response spectrum, the Y-axis acceleration response spectrum, and the Z-axis acceleration response spectrum, the damage assessment information corresponding to the acceleration response spectrum can be determined based on the spectrum line comparison results at the horizontal position in the acceleration response spectrum, such as Figure 3a The X-axis acceleration response spectrum is shown. Figure 3b The Y-axis acceleration response spectrum is shown. Figure 3c The Z-axis acceleration response spectrum is shown, where the dotted line is the design spectrum and the solid line is the response spectrum. According to the positional relationship between the design spectrum and the response spectrum at the horizontal position, if the response spectrum is above the design spectrum, it indicates that there is no damage. The damage assessment information corresponding to each acceleration response spectrum can be determined. Furthermore, when the spectral line comparison results of the X-, Y-, and Z-axis acceleration response spectra are all undamaged (i.e., damage assessment information), it can be determined that the post insulator is not damaged under the action of the earthquake (i.e., earthquake damage situation).

[0099] In an optional embodiment, the earthquake damage of the monitored post insulator can be verified through power outage detection. For example, it is monitored that the post insulator is not damaged by the earthquake. During the annual power outage, it is detected that the post insulator has no loose screws or bottom cracks. In addition, no abnormalities are found through on-site inspection of the natural frequency and damping ratio. The power outage detection situation can be expressed in the following way:

[0100] On-site investigation of X-axis natural frequency and damping ratio

[0101]

[0102] On-site investigation of Y-axis natural frequency and damping ratio

[0103]

[0104] On-site investigation of Z-axis natural frequency and damping ratio

[0105]

[0106] Power outage detection can also be Figure 4a , Figure 4b , Figure 4c shown.

[0107] In this embodiment, for each acceleration response spectrum, based on the spectrum line comparison result at the target position in the acceleration response spectrum, the damage assessment information corresponding to the acceleration response spectrum is determined, and then according to the damage assessment information corresponding to each acceleration response spectrum, the seismic damage condition of the post insulator is determined, so that the damage condition of the monitored post insulator under the action of earthquake can be accurately assessed.

[0108] In one embodiment, Figure 5 As shown, a flow chart of another method for monitoring earthquake damage of a post insulator is provided. In this embodiment, the method comprises the following steps:

[0109] In step 501, the initial acceleration data of the post insulator collected under the action of earthquake is obtained; the initial acceleration data includes multiple characteristic acceleration sets corresponding to each time point in the target time period; the acceleration values ​​in each characteristic acceleration set have the same coordinate axis component information. In step 502, for each time point, the characteristic acceleration sets corresponding to the time point are sorted by absolute value, and the maximum absolute value in each characteristic acceleration set is used as the first characteristic acceleration value. In step 503, multiple first characteristic acceleration values ​​corresponding to the time point are determined. In step 504, the time point includes integer time points, and according to the multiple first characteristic acceleration values ​​corresponding to the integer time points, a target amplification factor table is determined from multiple preset amplification factor tables; each amplification factor table has a matching first characteristic acceleration value; the amplification factor table includes multiple specified amplification factors corresponding to each integer time point. In step 505, for each integer time point, according to the multiple specified amplification factors, the multiple first characteristic acceleration values ​​corresponding to the integer time point are amplified respectively to obtain multiple second characteristic acceleration values ​​corresponding to the integer time point. In step 506, the time points include non-integer time points, and for each non-integer time point, the target integer time point corresponding to the non-integer time point is determined. In step 507, the multiple first characteristic acceleration values ​​corresponding to the non-integer time point are amplified respectively according to the multiple specified amplification coefficients corresponding to the target integer time point to obtain the multiple second characteristic acceleration values ​​corresponding to the non-integer time point. In step 508, based on the multiple second characteristic acceleration values ​​corresponding to each of the time points and the preset reference spectrum lines, multiple acceleration response spectra are constructed, and the seismic damage of the post insulator is determined according to the spectrum line comparison results of each of the acceleration response spectra; each acceleration response spectrum corresponds to the specified coordinate axis component information. It should be noted that the specific definition of the above steps can refer to the specific definition of a post insulator seismic damage monitoring method mentioned above, which will not be repeated here.
