Description

Technical Field

[0001] The present application relates to the technical field of transmission tower displacement measurement, and in particular to a method, device, computer equipment, computer-readable storage medium and computer program product for determining transmission tower displacement. Background Art

[0002] As a key component of the power system, the structural stability of the transmission tower is directly related to the safety and reliability of power supply. However, due to being outdoors for a long time, the transmission tower must withstand the influence of factors such as wind, snowfall, and earthquakes, which may cause the transmission tower to tilt, causing the positions of the transmission tower to be displaced compared to the original position, resulting in reduced structural stability and safety of the transmission tower. If the displacement of the transmission tower is too large, it may cause the wires connected to the transmission tower to break, or even cause accidents such as the collapse of the transmission tower, affecting the safe and stable operation of the power system.

[0003] Based on this, in traditional technology, manual inspection is usually used to regularly detect the displacement of transmission towers. However, manual inspection is inefficient and has large errors. It is also difficult to carry out in bad weather, and it is impossible to monitor the displacement changes of transmission towers in real time.

[0058] 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.

[0059] The method for determining the displacement of a transmission tower provided in an embodiment of the present application can be applied in an application environment as shown in FIG1 . Among them, the server 102 can be connected to the inclination sensor 104 installed on the transmission tower so as to obtain at least two inclinations measured by the inclination sensor 104 installed on each segment of the transmission tower. The data storage system can store the data that the server 102 needs to process. The data storage system can be integrated on the server 102, or it can be placed on the cloud or other network servers. Specifically, the server 102 can divide the transmission tower into multiple segments according to the received instructions, for example, segment a transmission tower with a known total length according to the division rules indicated by the instruction (internal operation of the computer). Furthermore, for each segment, the server 102 may first obtain the segment length of the segment, and determine the inclination sensor 104 installed on the segment from the multiple inclination sensors 104 actually installed on the transmission tower, thereby obtaining at least two inclination angles measured by the inclination sensor 104 by communicating with the inclination sensor 104 actually installed on the segment, wherein the inclination angle is the displacement direction of the highest point of the central axis of the segment in the longitudinal section of the transmission tower, and the angle between the vertical axis direction of the coordinate system corresponding to the segment, and the longitudinal sections corresponding to different inclination angles are perpendicular to each other. Furthermore, the server 102 may determine the lateral displacement of the highest point of the central axis of the segment based on the segment length and at least two inclination angles, wherein the lateral displacement refers to the displacement of the highest point of the central axis of the segment relative to the lowest point of the central axis of the segment in the horizontal plane, thereby accumulating the lateral displacements of multiple segments to obtain the lateral displacement of the top of the transmission tower. The server 102 may be an independent physical server, a server cluster or a distributed system composed of multiple physical servers, or a cloud server providing cloud computing services. The inclination sensor 104 may be used to measure the angle between the displacement direction (acceleration direction) and the gravity direction of an object in different planes in a preset coordinate system.

[0060] In an exemplary embodiment, as shown in FIG2 , a method for determining the displacement of a transmission tower is provided, and the method is described by taking the application of the method to the server 102 in FIG1 as an example, including the following steps 202 to 208. Among them:

[0061] Step 202, dividing the transmission tower into a plurality of sections.

[0062] The longer the segment lengths are, the more accurate the subsequent calculation results will be, but this will also increase the amount of calculation and the cost of setting up the inclination sensor. In this embodiment, the transmission tower is segmented according to the actual structure of the transmission tower.

[0063] Optionally, the server may divide the transmission tower into multiple sections according to the received instructions. For example, according to the received instructions, the transmission tower with a known total length is divided into sections according to the distribution positions of the crossarms on the transmission tower (internal operation of the computer). After the transmission tower to be tested is divided into sections, each section has a crossarm assigned to the section, and the highest point of the central axis of the section is on the line connecting the two crossarm points on the crossarm. The crossarm is a bracket extending from both sides of the transmission tower, which can be used to support overhead wires, and the vertices on both sides of the crossarm are the crossarm points.

[0064] Exemplarily, the server may pre-store relevant data of the transmission tower to be tested, such as the distribution position of the crossarms on the transmission tower and the total length of the transmission tower. Based on this, as shown in FIG3 (only some crossarm points are marked in FIG3), a schematic diagram of the transmission tower to be tested after segmentation is provided. In FIG3, when the total length L of the transmission tower is known and the distribution position of the crossarms on the transmission tower is known, the server may divide the transmission tower in FIG3 into four segments with lengths of L1, L2, L3, and L4, respectively, and use the crossarms as the dividing line between each segment, that is, the line between two crossarm points belonging to the same crossarm is used as the dividing line. After the transmission tower in FIG3 is segmented, crossarm 1 is divided into segments with a length of L1, crossarm 2 is divided into segments with a length of L2, crossarm 3 is divided into segments with a length of L3, and crossarm 4 is divided into segments with a length of L4.

[0065] Step 204, for each segment, obtain the segment length of the segment and at least two inclinations measured by the inclination sensor installed on the segment; the inclination is the angle between the displacement direction of the highest point of the central axis of the segment in the longitudinal section of the transmission tower and the vertical axis direction of the coordinate system corresponding to the segment, and the longitudinal sections corresponding to different inclinations are perpendicular to each other.

[0066] Among them, an inclination sensor is installed on at least one crossarm point of the crossarm in each section (due to the structural particularity of the transmission tower, the deformation of the bottom of the transmission tower is usually small and can be ignored. Therefore, there is no need to install an inclination sensor at the bottom of the transmission tower).

[0067] Optionally, for each segment, the server may first obtain the segment length of the segment, and obtain at least two inclinations measured by the inclination sensor by communicating with the inclination sensor installed in the segment.

[0068] For example, taking the segmented transmission tower in FIG3 as an example, a tilt sensor can be installed on at least one cross arm point of each of cross arm 1, cross arm 2, cross arm 3, and cross arm 4. As shown in FIG4, a schematic diagram of the installation position of the tilt sensor on the transmission tower is provided, wherein the tilt sensor 1 is installed on a cross arm point of cross arm 1 (belonging to the first segment with a length of L1), the tilt sensor 2 is installed on a cross arm point of cross arm 2 (belonging to the second segment with a length of L2), the tilt sensor 3 is installed on a cross arm point of cross arm 3 (belonging to the third segment with a length of L3), and the tilt sensor 4 is installed on a cross arm point of cross arm 4 (belonging to the fourth segment with a length of L4).

[0069] Step 206, based on the segment length and at least two inclination angles, determine the lateral displacement of the highest point of the central axis of the segment; the lateral displacement refers to: the displacement of the highest point of the central axis of the segment relative to the lowest point of the central axis of the segment in the horizontal plane.

[0070] Optionally, for each segment, the server can determine the lateral displacement of the highest point of the central axis of the segment efficiently, accurately and in real time based on the segment length and at least two inclinations measured in real time by an inclination sensor installed on the segment without manual measurement.

[0071] Step 208, accumulating the lateral displacements of the multiple segments to obtain the lateral displacement of the top of the transmission tower.

[0072] It should be noted that due to the particularity of the transmission tower structure, the deformation of each segment of the transmission tower is mainly the lateral displacement or deformation caused by deflection. The axial elongation of each segment is relatively small in actual deformation and can be ignored relative to its segment length. Therefore, when calculating the overall deformation of the transmission tower structure, the influence of the axial elongation is not considered. In addition, the point with the largest displacement in the transmission tower is usually the top of the tower. Therefore, in this embodiment, it is necessary to determine the lateral displacement of the top of the transmission tower to evaluate the displacement (degree of inclination) of the transmission tower and then evaluate the risk of the transmission tower. Based on this, the server can accumulate the lateral displacements of multiple segments, and efficiently, accurately and in real time obtain the lateral displacement of the top of the transmission tower, providing strong data support for the risk assessment of the transmission tower.

[0073] The above-mentioned method for determining the displacement of a transmission tower first divides the transmission tower into multiple sections. For each section, first obtain the section length of the section and at least two inclination angles measured by the inclination sensor installed on the section, wherein the inclination angle is the angle between the displacement direction of the highest point of the central axis of the section in the longitudinal section of the transmission tower and the vertical axis direction of the coordinate system corresponding to the section, and the longitudinal sections corresponding to different inclination angles are perpendicular to each other. Further, based on the section length and at least two inclination angles, the lateral displacement of the highest point of the central axis of the section is determined, wherein the lateral displacement refers to the displacement of the highest point of the central axis of the section relative to the lowest point of the central axis of the section in the horizontal plane, so that the lateral displacement of the top of the transmission tower can be obtained by accumulating the lateral displacements of multiple sections. During the whole process, no manual inspection is required, and the displacement of the transmission tower can be efficiently, accurately and in real time monitored by the at least two inclination angles corresponding to each section measured in real time by the inclination sensor.

[0074] In an exemplary embodiment, for each segment, a coordinate system is configured in the inclination sensor installed in the segment; the coordinate system is constructed based on the highest point of the central axis of the segment when the transmission tower is not tilted;

[0075] One of the longitudinal sections corresponding to different inclination angles passes through the cross arm point of the transmission tower, and the intersection line of the longitudinal sections corresponding to different inclination angles is the central axis of the transmission tower when it is not tilted;

[0076] For each segment, the coordinate system installed in the inclination sensor of the segment is constructed in the following way: the highest point of the central axis of the segment when the transmission tower is not tilted is taken as the origin of the coordinate system, the direction of gravity is taken as the vertical axis direction, the direction parallel to the first longitudinal section passing through the cross arm point is taken as the longitudinal axis direction, the second longitudinal section perpendicular to the first longitudinal section is determined, and the direction parallel to the second longitudinal section is taken as the horizontal axis direction to construct the coordinate system.

[0077] Exemplarily, for each segment, the inclination angle measured in real time by the inclination sensor installed on the segment includes: a first inclination angle and a second inclination angle. The first inclination angle refers to the angle between the displacement direction of the highest point of the central axis of the segment in the first longitudinal section of the transmission tower and the vertical axis direction of the coordinate system corresponding to the segment; the second inclination angle refers to the angle between the displacement direction of the highest point of the central axis of the segment in the second longitudinal section of the transmission tower and the vertical axis direction of the coordinate system corresponding to the segment.

[0078] Based on this, as shown in Figure 5, a schematic diagram of the first inclination and the second inclination measured by the inclination sensor is provided. Taking the first segment with a length of L1 in the transmission tower shown in Figure 3 as an example, assuming that the highest point of the central axis of the first segment is at O1 when the transmission tower is not tilted, based on the above-mentioned coordinate system construction rules, O1 can be used as the origin of the coordinate system of the inclination sensor 1 installed on the first segment, and the direction of gravity can be used as the vertical axis direction (determine the Z-axis direction). The ZO1Y plane of the coordinate system is the first longitudinal section passing through all the cross arm points of the transmission tower, and the ZO1X plane of the coordinate system is the second longitudinal section. The second longitudinal section is perpendicular to the first longitudinal section, and the intersection line of the first longitudinal section and the second longitudinal section is the central axis of the transmission tower when it is not tilted (the central axis of the transmission tower is parallel to the gravity direction when it is not tilted). Based on this, if the highest point of the central axis of the first section of the transmission tower is at O1' after the tilt, the displacement direction caused by the tilt is O1→O1', and the first inclination angle α1 refers to: the angle between the projection of the displacement direction (O1→O1') on the first longitudinal section (ZO1Y plane) and the Z axis, and the second inclination angle β1 refers to: the angle between the projection of the displacement direction (O1→O1') on the second longitudinal section (ZO1X plane) and the Z axis. Among them, during the tilting process of the first segment, the inclination sensor 1 can measure the displacement direction (acceleration direction) of the cross arm point on the first segment in the ZO1Y plane, and use the angle between the acceleration direction and the gravity direction in the ZO1Y plane as the first inclination angle α1 of the cross arm point where the inclination sensor 1 is located in the tilting process. Since the cross arm point where the inclination sensor 1 is located and the highest point of the central axis of the first segment are both in the first segment (all points in the same segment can be regarded as one), the first inclination angle α1 is also the first inclination angle α1 of the highest point of the central axis of the first segment in the tilting process. Similarly, during the tilting process of the first segment, the inclination sensor 1 can measure the displacement direction (acceleration direction) of the cross arm point on the first segment in the ZO1X plane, and use the angle between the acceleration direction and the gravity direction in the ZO1X plane as the second inclination angle β1 of the cross arm point where the inclination sensor 1 is located during the tilting process. Since the cross arm point where the inclination sensor 1 is located and the highest point of the central axis of the first segment are both in the first segment (all points in the same segment can be regarded as one), the second inclination angle β1 is also the second inclination angle β1 of the highest point of the central axis of the first segment during the tilting process.

[0079] It should be noted that, in this embodiment, for each segment, the inclination sensor installed on the segment can measure the first inclination and the second inclination of the highest point of the central axis of the segment caused by the inclination of the transmission tower.

[0080] In this embodiment, a coordinate system can be set up respectively for the inclination sensor installed on each segment so that the inclination sensor can measure in real time the first inclination angle and the second inclination angle between the highest point of the central axis of the corresponding segment in the longitudinal section of the transmission tower and the vertical axis direction of the coordinate system corresponding to the segment.

[0081] In some embodiments, determining the lateral displacement of the highest point of the central axis of the segment based on the segment length and the at least two inclination angles includes:

[0082] Based on at least two inclination angles, determine a first angle between the displacement direction of the highest point of the central axis of the segment and the vertical axis direction of the coordinate system corresponding to the segment;

[0083] Obtain the straight-line distance between the highest point of the central axis of the segment and the lowest point of the central axis of the transmission tower, and the total length of the transmission tower, and determine the height of the highest point of the central axis of the segment according to the straight-line distance, the first angle, and the total length;

[0084] Determine the second angle between the segmented central axis and the horizontal plane based on the straight-line distance and the height of the highest point of the central axis;

[0085] According to the segment length and the second angle of the segment, the lateral displacement of the highest point of the central axis of the segment is determined.

[0086] Optionally, for each segment, the server may first obtain the first inclination angle and the second inclination angle measured by the inclination sensor installed on the segment, and then calculate the first angle between the displacement direction of the highest point of the central axis of the segment and the vertical axis direction of the coordinate system corresponding to the segment based on the first inclination angle and the second inclination angle. Further, the server may determine the straight-line distance between the highest point of the central axis of the segment and the lowest point of the central axis of the transmission tower based on the length of each segment, and then determine the height difference of the highest point of the central axis of the segment before and after tilting based on the straight-line distance and the first angle, and then determine the real-time height of the highest point of the central axis of the segment after tilting based on the straight-line distance between the highest point of the central axis of the segment and the lowest point of the central axis of the transmission tower and the height difference of the highest point of the central axis of the segment before and after tilting. Furthermore, the server can determine the second angle between the central axis of the segment and the horizontal plane based on the straight-line distance between the highest point of the central axis of the segment and the lowest point of the central axis of the transmission tower and the real-time height of the highest point of the central axis of the segment after tilting, and then determine the lateral displacement of the highest point of the central axis of the segment according to the segment length and the second angle.

[0087] For example, as shown in FIG6 , taking the i-th segment as an example, a schematic diagram of determining the lateral displacement based on the first inclination angle and the second inclination angle measured by the inclination sensor is provided. i is the highest point of the central axis of the ith segment before tilting, O i+1 is the lowest point of the central axis of the ith segment before tilting, O i+1 That is, the highest point of the central axis of the i+1th segment before tilting occurs, and O i ' is the highest point of the central axis of the i-th segment after tilting, O i+1' is the lowest point of the central axis of the i-th segment after tilting, O i+1 ', that is, the highest point of the central axis of the i+1th segment after the tilt occurs. A is the lowest point of the central axis of the transmission tower before the tilt occurs (regarded as the ground), and B is i 'Projected point on the Z axis, CO i+1 'For BO i ', CO i ' is the lateral displacement of the i-th segment to be calculated. Based on this, the server can calculate the lateral displacement CO through the following process i ':

[0088] 1. For the i-th segment, the server can first obtain the first inclination angle α measured by the inclination sensor i installed in the i-th segment i and the second inclination angle β i , thus calculating the displacement direction of the highest point of the central axis of the i-th segment (O i →O i The first angle γ between ') and the Y axis i Specifically, if in the coordinate system configured in the inclination sensor i, i 'The coordinates are (x, y, z), then based on the Pythagorean theorem of triangles, the following formula is satisfied:

[0089] (1)

[0090] (2)

[0091] (3)

[0092] Based on formulas (1) to (3), the displacement direction of the highest point of the central axis of the i-th segment (O i →O i The first angle between ') and the Y axis Among them, the first inclination angle α i and the second inclination angle β i is the known number measured by inclination sensor i.

[0093] 2. Although there are slight differences in the degree of inclination of each segment in the transmission tower (the higher the segment, the more serious the inclination), for the entire transmission tower (usually the lateral displacement of the top of the transmission tower is extremely small relative to the total length of the entire transmission tower), the distance from a certain point on the transmission tower to the bottom of the tower (the lowest point of the central axis of the transmission tower) before and after the inclination can be considered the same. Therefore, for the i-th segment, the straight-line distance from the highest point of the central axis to the lowest point of the central axis of the transmission tower before and after the inclination is the same, that is, AO in Figure 6 i '≈AO iBased on this, the server can accumulate the lengths of multiple segments below the i-th segment based on the known lengths of each segment to obtain the straight-line distance AO between the highest point of the central axis of the i-th segment and the lowest point of the central axis of the transmission tower. i ', that is, AO i , and obtain the total length L of the transmission tower. Further, the server can calculate the total length L of the transmission tower according to the straight-line distance AO. i '(also known as AO i ), the first angle γ i And the total length L, determine the real-time height AB of the highest point of the central axis of the i-th segment after tilting. The specific process is as follows:

[0094] First, based on formula (4), determine the height difference BO of the highest point of the central axis of the i-th segment before and after tilting: i :

[0095] (4)

[0096] Among them, due to the macroscopic AO i With AO i 'Approximately equal length, triangle AO i O i ' can be regarded as an isosceles triangle, then , AO i and AO i ' is the known straight line distance, the first angle γ i It has been calculated based on formulas (1) to (3).

[0097] Furthermore, based on formula (5), taking the lowest point A of the central axis of the transmission tower as the ground, the real-time height AB of the highest point of the central axis of the i-th segment after tilting can be calculated:

[0098] AB=AO i -BO i (5)

[0099] Among them, AO i is the known straight-line distance, BO i It has also been calculated based on formula (4).

[0100] 3. The server can calculate the straight-line distance AO based on the highest point of the central axis of the i-th segment and the lowest point of the central axis of the transmission tower. i ', and the height AB of the highest point of the central axis of the segment after tilting, determine the second angle ε between the central axis of the segment and the horizontal plane i , and then based on the segment length L of the i-th segment i (That is, O i 'O i+1 ') and the second angle εi , determine the lateral displacement CO of the highest point of the central axis of the i-th segment i ', the specific process is as follows:

[0101] First based on O i+1 'Make BO i 'The vertical line CO i+1 ', because sin(ε i )=AB / AO i ', that is, the second angle ε can be calculated by formula (6) i :

[0102] (6)

[0103] Among them, AB has been calculated based on formula (5), AO i ' is the known straight-line distance, so the lateral displacement CO of the highest point of the central axis of the i-th segment can be calculated by formula (7). i ':

[0104] (7)

[0105] Among them, ε i Based on formula (6), L i is the known segment length of the i-th segment.

[0106] Based on the above formulas (1) to (7), the server can calculate the lateral displacement corresponding to the i-th segment, that is, the displacement of the highest point of the central axis of the i-th segment relative to the lowest point of the central axis of the i-th segment in the horizontal plane.

[0107] In this embodiment, for each segment, based on the first inclination angle and the second inclination angle measured in real time by the inclination sensor installed on the segment, the horizontal displacement of the highest point of the central axis of the segment after tilting relative to the lowest point of the central axis of the segment after tilting can be calculated efficiently (faster than manual patrol measurement), accurately (more accurate than manual patrol measurement), and in real time.

[0108] In a possible implementation, the method for determining the displacement of a transmission tower further includes:

[0109] Obtain multiple climate factors, and determine the climate risk assessment value corresponding to each climate factor based on the climate data corresponding to each climate factor in the environment where the transmission tower is located;

[0110] Determine a tilt risk assessment value corresponding to the lateral displacement of the tower top, and determine a target risk assessment value of the transmission tower based on the tilt risk assessment value and a plurality of climate risk assessment values;

[0111] Determine the risk level of the transmission tower based on the target risk assessment value.

[0112] Among them, various climate factors include but are not limited to: wind speed, ice thickness, snow thickness, rainfall, earthquake intensity, etc.

[0113] Optionally, the server may first obtain a variety of climate factors (which may be imported into the server by the operation and maintenance personnel of the power transmission system), and obtain the climate data corresponding to each climate factor in the environment where the power transmission tower is located through various meteorological monitors deployed in the power transmission system, such as wind speed monitors, ice thickness monitors, snow thickness monitors, rainfall monitors, earthquake intensity monitors, etc. Further, the server may determine the climate risk assessment value corresponding to each climate factor according to the climate data corresponding to each climate factor in the environment where the power transmission tower is located according to the preset climate risk assessment rules, and determine the tilt risk assessment value corresponding to the lateral displacement of the tower top according to the preset tower tilt risk assessment rules, thereby determining the target risk assessment value of the power transmission tower based on the tilt risk assessment value and multiple climate risk assessment values, and finally, determine the risk level of the power transmission tower according to the preset risk level assessment rules and the target risk assessment value.

[0114] Exemplarily, the preset climate risk assessment rules can specifically be: according to the mapping relationship between climate data and climate risk assessment values, determine the climate risk assessment value corresponding to the climate data. Taking the climate data monitored by the wind speed monitor and the ice thickness monitor as an example, some of the mapping relationships between climate data and climate risk assessment values ​​can be specifically shown in Table 1:

[0115] Table 1 Partial mapping relationship between climate data and climate risk assessment values

[0116]

[0117] Among them, the specific climate risk assessment value corresponding to the specific value of each climate data can be calculated by the server according to the preset calculation rules, or determined manually by referring to the mapping relationship according to the empirical method.

[0118] For example, the preset tower tilt risk assessment rule can specifically be: according to the mapping relationship between the tower top lateral displacement and the tilt risk assessment value, determine the tilt risk assessment value corresponding to the tower top lateral displacement. Among them, the partial mapping relationship between the tower top lateral displacement and the tilt risk assessment value can be specifically shown in Table 2:

[0119] Table 2 Partial mapping relationship between tower top lateral displacement and tilt risk assessment value

[0120]

[0121] Among them, the specific tilt risk assessment value corresponding to the specific value of the tower top lateral displacement can be calculated by the server according to a preset calculation rule, or determined manually by referring to the mapping relationship based on an empirical method.

[0122] In this embodiment, taking into account the displacement of the tower top, wind speed, ice or snow covering the transmission tower, or earthquake, all of which may increase the inclination of the transmission tower and thus increase the risk of the transmission tower toppling, the target risk assessment value of the transmission tower can be determined in combination with the lateral displacement of the tower top and various climatic factors, so as to conduct a more comprehensive risk assessment of the transmission tower, so that the operation and maintenance personnel of the power system can take operation and maintenance measures for the transmission towers with high risk levels in a timely manner by referring to the risk levels obtained by the assessment.

[0123] In one embodiment, determining a target risk assessment value of a transmission tower based on a tilt risk assessment value and a plurality of climate risk assessment values ​​comprises:

[0124] Obtaining the assessment weight corresponding to the tilt risk assessment value and the assessment weight corresponding to each climate risk assessment value;

[0125] Based on the assessment weight corresponding to the tilt risk assessment value and the assessment weight corresponding to each climate risk assessment value, the tilt risk assessment value and multiple climate risk assessment values ​​are accumulated to obtain a target risk assessment value of the transmission tower.

[0126] Among them, the assessment weight corresponding to the tilt risk assessment value and the assessment weight corresponding to each climate risk assessment value can be set by the operation and maintenance personnel of the power system based on the empirical method.

[0127] Optionally, the server may first obtain the assessment weights corresponding to each tilt risk assessment value and the assessment weights corresponding to each climate risk assessment value, and then based on the assessment weights corresponding to the tilt risk assessment values ​​and the assessment weights corresponding to each climate risk assessment value, accumulate the tilt risk assessment values ​​and multiple climate risk assessment values ​​to obtain the target risk assessment value of the transmission tower.

[0128] For example, the tilt risk assessment value and each climate risk assessment value can be used as a state quantity for reference. If there are n state quantities, there are also n corresponding assessment weights. The target risk assessment value P of the transmission tower can be determined in the following way:

[0129] (8)

[0130] Among them, Z j is the jth state variable, μ j is the evaluation weight of the j-th state quantity.

[0131] Further, after determining the target risk assessment value P of the transmission tower, the server may determine the risk level of the transmission tower according to the target risk assessment value according to a preset risk level assessment rule, wherein the risk level assessment rule may be specifically as shown in Table 3:

[0132] Table 3 Risk level assessment rules

[0133]

[0134] In this embodiment, the risk level of the transmission tower can be judged based on the tilt risk assessment value and multiple climate risk assessment values ​​calculated in real time, and an early warning can be issued based on the judgment result to provide theoretical guidance for the operation and maintenance personnel of the power system.

[0135] In a detailed embodiment, based on the above embodiments, as shown in FIG7 , a flow chart of a method for real-time prediction of risk level of a transmission tower is provided, which mainly includes the following steps:

[0136] Step 702, dividing the transmission tower into multiple sections.

[0137] Step 704: for each segment, obtain the segment length of the segment and at least two inclination angles measured in real time by an inclination sensor installed on the segment.

[0138] The inclination angle is the angle between the displacement direction of the highest point of the central axis of the segment in the longitudinal section of the transmission tower and the vertical axis direction of the coordinate system corresponding to the segment, and the longitudinal sections corresponding to different inclination angles are perpendicular to each other. One of the longitudinal sections corresponding to different inclination angles passes through the cross arm point of the transmission tower, and the intersection line of the longitudinal sections corresponding to different inclination angles is the central axis of the transmission tower when it is not tilted.

[0139] Wherein, for each segment, a coordinate system is configured in the inclination sensor installed in the segment, and the coordinate system is constructed based on the highest point of the central axis of the segment when the transmission tower is not tilted. For each segment, the coordinate system installed in the inclination sensor of the segment is constructed in the following manner: the highest point of the central axis of the segment when the transmission tower is not tilted is used as the origin of the coordinate system, the direction of gravity is used as the vertical axis direction, the direction parallel to the first longitudinal section passing through the cross arm point is used as the longitudinal axis direction, a second longitudinal section perpendicular to the first longitudinal section is determined, and the direction parallel to the second longitudinal section is used as the horizontal axis direction to construct the coordinate system.

[0140] Step 706: Based on at least two inclination angles, determine a first angle between the displacement direction of the highest point of the central axis of the segment and the vertical axis direction of the coordinate system corresponding to the segment.

[0141] Step 708, obtain the straight-line distance between the highest point of the central axis of the segment and the lowest point of the central axis of the transmission tower, and the total length of the transmission tower, and determine the height of the highest point of the central axis of the segment based on the straight-line distance, the first angle and the total length.

[0142] Step 710, determining a second angle between the central axis of the segment and the horizontal plane based on the straight-line distance and the height of the highest point of the central axis.

[0143] Step 712, determining the lateral displacement of the highest point of the central axis of the segment according to the segment length and the second angle of the segment.

[0144] The lateral displacement refers to the displacement of the highest point of the central axis of the segment relative to the lowest point of the central axis of the segment in the horizontal plane.

[0145] Step 714, accumulating the lateral displacements of the multiple segments to obtain the lateral displacement of the top of the transmission tower, and determining the tilt risk assessment value corresponding to the lateral displacement of the top of the tower.

[0146] Step 716, obtaining multiple climate factors, and determining the climate risk assessment value corresponding to each climate factor according to the real-time climate data corresponding to each climate factor in the environment where the transmission tower is located.

[0147] Step 718, obtaining the assessment weight corresponding to the tilt risk assessment value and the assessment weight corresponding to each climate risk assessment value.

[0148] Step 720, based on the assessment weight corresponding to the tilt risk assessment value and the assessment weight corresponding to each climate risk assessment value, the tilt risk assessment value and multiple climate risk assessment values ​​are accumulated to obtain a target risk assessment value of the transmission tower.

[0149] Step 722, determining the risk level of the transmission tower according to the target risk assessment value.

[0152] The analysis module is used to calculate the real-time lateral displacement corresponding to each segment based on the first inclination angle and the second inclination angle detected by the inclination sensor of each segment, thereby calculating the real-time lateral displacement of the top of the transmission tower, and then determining the inclination risk assessment value; based on the climate data corresponding to each climate factor, calculate the climate risk assessment value corresponding to each climate factor; based on the inclination risk assessment value and multiple climate risk assessment values, determine the target risk assessment value and risk level of the transmission tower; according to the risk level of the transmission tower, determine whether it is necessary to feedback early warning information;

[0153] The early warning module is used to feedback early warning information when the analysis module determines that early warning information needs to be fed back.
