Description

Technical Field

[0001] The present disclosure relates to the field of electrical detection technology, and in particular to a method and device, equipment, and storage medium for detecting hidden dangers between outdoor objects and power transmission lines. Background Art

[0002] With the rapid development of society and the growing demand for electricity, the safe operation of transmission lines is crucial to ensuring the stability of the social economy. However, in the operation of transmission lines, super-high objects near transmission lines have become a common safety hazard. For example, high-speed growing branches may touch high-voltage wires and form tree barriers, which will increase the risk of insulation failure and short circuit of the wires and pose a threat to the safe operation of the system. Alternatively, if trees are not pruned and maintained in time, overly high trees may collapse in severe weather or emergencies, directly affecting the stability and reliability of transmission lines. Especially under severe meteorological conditions such as storms, ice and snow, the transmission line route is easily blown by the wind and contacted with super-high objects near it. This contact may cause line short circuit and grounding fault. For example, when branches touch power lines, current will flow directly through the branches, causing damage to wires and equipment; when wires touch buildings or other metal poles, current may flow through the grounding path, causing danger. Therefore, it is necessary to monitor the situation of super-high objects near transmission lines in real time.

[0003] At present, in the power sector, manual inspections are mainly used to timely discover and eliminate hidden dangers between objects and transmission lines. Through manual field visits to transmission line towers, infrared ranging tools are used to remotely measure the height of trees next to the transmission lines, and then calculate whether the distance from the trees to the lines exceeds the safe distance. However, manual inspections are inefficient, costly, and timeliness cannot be guaranteed. To solve this problem, drone patrols have been used to replace manual inspections. The data collected by drones need to be calculated through complex algorithms in the later stage. The measurement cost is high, the calculation is complex, and uninterrupted real-time patrols cannot be achieved. In the end, some personnel still need to go to the site for measurement, which is also inefficient and timeliness cannot be guaranteed. Summary of the invention

[0004] In order to overcome the problems existing in the related art, the present disclosure provides a method and device, equipment, and storage medium for detecting hidden dangers between outdoor objects and transmission lines. The height of the object is identified by satellite images, and the height of the object is combined with the height of the transmission line to detect safety hazards between the object and the transmission line. The detection process is simple and fast, and real-time detection can be achieved, which solves the problems of low efficiency, high cost, and lack of timeliness in the prior art for detecting hidden dangers between outdoor objects and transmission lines.

[0005] According to a first aspect of an embodiment of the present disclosure, a method for detecting hidden dangers between an outdoor object and a power transmission line is provided, comprising:

[0006] Identify the height of the target object in the target area based on the image including the target area taken by the satellite;

[0007] Determine the types of transmission lines within the target area;

[0008] According to the height of the target object, the type of the transmission line and the height of the transmission line, the potential safety hazard between the target object and the transmission line is detected.

[0009] In this embodiment, the height of the target object is identified using satellite images, and the safety hazard between the target object and the transmission line is detected based on the height of the target object, the type of transmission line and the height of the transmission line. The detection process is simple and fast, and non-contact detection can be achieved without manual labor, and real-time detection can be achieved.

[0010] In one embodiment, the detecting of potential safety hazards between the target object and the transmission line according to the height of the target object, the type of the transmission line and the height of the transmission line includes:

[0011] If the type of the power transmission line in the target area is a high-voltage power transmission line, determining whether the top height of the target object is lower than the high-voltage power transmission line in the target area;

[0012] If the top height of the target object is lower than the high-voltage transmission line in the target area, a first height difference between the transmission line in the target area and the top of the target object is calculated, and it is determined whether the first height difference is greater than a preset first threshold;

[0013] If the top height of the target object is not lower than the high-voltage transmission line in the target area, or if the first height difference is not greater than a first threshold, it is determined that there is a safety hazard between the target object and the transmission line.

[0014] In this embodiment, when the transmission line is a high-voltage transmission line, it is only necessary to compare the top height of the target object and the height of the high-voltage transmission line, and when the top height of the target object is lower than the high-voltage transmission line in the target area, it is determined whether the first height difference between the high-voltage transmission line and the top of the target object is greater than a preset threshold, so that the existence of a safety hazard between the target object and the transmission line can be detected. The detection process does not require complex algorithms, the detection process is fast, and contactless detection can be achieved without manual labor.

[0015] In one embodiment, the detecting of potential safety hazards between the target object and the transmission line according to the height of the target object, the type of the transmission line and the height of the transmission line further includes:

[0016] If the type of the power transmission line in the target area is a civil power transmission line, dispatching a drone to the target area to detect whether the target object is a tree or a building;

[0017] If the target object is a tree, the height of the target object identified based on the satellite image is used as the top height of the tree crown, and the drone is dispatched to detect the bottom height of the tree crown;

[0018] Determining whether the top height of the tree canopy is lower than the civil power transmission line in the target area;

[0019] If the top height of the tree crown is lower than the civil power transmission line in the target area, calculating a second height difference between the top height of the tree crown and the civil power transmission line in the target area, and determining whether the second height difference is greater than a preset second threshold;

[0020] If the top height of the tree crown is not lower than the civil power transmission line in the target area, determining whether the bottom height of the tree crown is higher than the civil power transmission line in the target area;

[0021] If the bottom height of the tree crown is higher than the civil power transmission line in the target area, a third height difference between the bottom of the tree crown and the civil power transmission line in the target area is calculated, and it is determined whether the third height difference is greater than a preset third threshold;

[0022] If the second height difference is not greater than the second threshold, or if the top height of the tree crown is not lower than the civil power transmission lines in the target area and the bottom height of the tree crown is not higher than the civil power transmission lines in the target area, or if the third height difference is not greater than the third threshold, it is determined whether there is a safety hazard between the target object and the transmission line.

[0023] In this embodiment, when the transmission line is a civil transmission line and the target object is a tree, it is only necessary to compare the top height and bottom height of the tree crown and the height of the civil transmission line. According to the height comparison result and the distance between the top of the tree crown and the transmission line or the distance between the bottom of the tree crown and the transmission line, it is possible to detect whether there is a safety hazard between the target object and the transmission line. The detection process does not require complex algorithms and the detection process is fast. Contactless detection can be achieved without manual labor.

[0024] In one embodiment, after dispatching the drone to the target area to detect whether the target object is a tree or a building, the method further includes:

[0025] If the target object is a building, determining whether the height of the building is higher than the civil power transmission lines in the target area;

[0026] If the height of the building is higher than the civil power transmission line in the target area, dispatching a drone to the target area to detect the lateral distance between the side of the building and the civil power transmission line;

[0027] Determining whether a lateral distance between the side of the building and the civil power transmission line is greater than a preset fourth threshold;

[0028] If the height of the building is higher than the civil power transmission line in the target area and the lateral distance between the side of the building and the civil power transmission line is not greater than a fourth threshold, it is determined that there is a safety hazard between the target object and the power transmission line.

[0029] In this embodiment, in this embodiment, when the transmission line is a civil transmission line and the target object is a building, it is only necessary to compare the height of the building and the height of the civil transmission line. According to the height comparison result, when the top of the building is higher than the transmission line, combined with the lateral distance between the side of the building and the transmission line, it is possible to detect whether there is a safety hazard between the target object and the transmission line. The detection process does not require complex algorithms, the detection process is fast, and contactless detection can be achieved without manual labor.

[0030] In one embodiment, determining the type of power transmission line in the target area includes:

[0031] According to an image including a target area taken by a satellite, identifying transmission line towers in the image and obtaining geographic coordinates of each identified transmission line tower;

[0032] According to the geographical coordinates of the transmission line towers, adjacent transmission line towers are connected to obtain the geographical coordinates of the transmission line between the adjacent transmission line towers;

[0033] The transmission lines in the target area are determined according to the geographical coordinates of the transmission lines and the pre-stored correspondence between the geographical coordinates of the transmission lines in the power system and the types of the transmission lines.

[0034] In this embodiment, by identifying the geographic coordinates of the transmission lines in the target area through satellite images, the transmission lines near the target object can be automatically determined without manual data entry, and the transmission lines far away from the target object and without safety hazards can be quickly filtered out, further reducing the number of comparison calculations and improving the efficiency of hazard detection.

[0035] In one embodiment, identifying a target object in the target area and determining the height of the target object based on an image of the target area taken by a satellite includes:

[0036] Acquire a first image taken by an optical multispectral satellite within a preset shooting date, and identify the first image to identify the top of the target object; wherein the first image includes a preset target area, and the target area includes the target object whose height is to be measured;

[0037] Get the geographic coordinate range of the top area of ​​the target object;

[0038] Acquire a second image captured by a twilight orbit satellite on the capture date and associated with the first image; wherein the association means that the second image includes a preset target area, and the time interval between the capture time of the second image and the capture time of the first image does not exceed a preset time threshold;

[0039] According to the geographic coordinate range of the top area of ​​the target object, embed the top area of ​​the target object in the second image, determine a shadow area outside the top area of ​​the target object in the second image, and determine the geographic coordinate range of the shadow area;

[0040] The height of the target object is determined according to the shooting angle when the second image is taken by the twilight orbit satellite, the solar altitude angle, and the geographical coordinate range of the shadow area.

[0041] In this embodiment, by identifying the top area of ​​the object in the first image taken by the optical multispectral satellite, and by embedding the top area of ​​the object in the first image in the second image taken by the dusk-dawn orbit satellite associated with it, the shadow area outside the top area of ​​the target object can be simply and quickly determined, thereby determining the height of the target object according to the shooting angle of the second image, the solar altitude angle, and the geographic coordinate range of the shadow area. By scheduling two different satellites, especially using the dusk-dawn orbit satellite, the shadow area can be quickly and accurately positioned, which is conducive to the rapid calculation of the height of the object.

[0042] In one embodiment, before acquiring the first image captured by the optical multispectral satellite within a preset capture date, the method further includes:

[0043] Determine the geographic location of the target area including the target object to be measured in height;

[0044] Determine, relative to a preset target area, a first moment when the sun is at its highest altitude and a second moment when the shadow of the target object is the longest within a preset shooting date;

[0045] The optical multi-spectral satellite closest to the target area at a first moment is used as the target optical multi-spectral satellite, and the dawn-dusk orbit satellite closest to the target area at a second moment is used as the target dawn-dusk orbit satellite;

[0046] Sending photography instructions to the target optical multispectral satellite and the target dawn-dusk orbit satellite;

[0047] A first image sent from a target optical multispectral satellite and a second image sent from a target dawn-dusk orbit satellite are received.

[0048] In this embodiment, the first moment when the sun is at its highest altitude and the second moment when the shadow of the target object is the longest within a preset shooting date are determined. The optical multispectral satellite and the target dawn-dusk orbit satellite closest to the target area at these two moments can be determined through the first moment and the second time. The satellite corresponding to the image required for later determination of the shadow area is accurately located, and there is no need to calculate the images of all satellites that can capture the target area. This can significantly reduce the amount of calculation in the entire method process and improve the efficiency of measuring the height of the target object.

[0052] The hidden danger detection module is used to detect the hidden danger between the target object and the transmission line according to the height of the target object, the type of the transmission line and the height of the transmission line.

[0066] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0067] Figure 1 is a flow chart of a method for detecting hidden dangers between an outdoor object and a power transmission line according to an exemplary embodiment. Figure 1As shown, the method includes the following steps S1-S3:

[0068] S1: Identify the height of the target object in the target area based on the image of the target area taken by the satellite.

[0069] Figure 2 FIG. 1 is a flow chart showing the height of a target object in a target area according to an image taken by a satellite according to an exemplary embodiment. Figure 2 As shown, the method may include the following steps S11-S15:

[0070] S11: Acquire a first image taken by an optical multispectral satellite within a preset shooting date, and identify the first image to identify the top of the target object.

[0071] Wherein, the first image includes a preset target area, and the target area includes a target object whose height is to be measured.

[0072] In this embodiment, the first image taken by the optical multispectral satellite is identified to identify the top of the object, such as the crown of a tree, the roof of a building, etc.

[0073] Since images taken by optical multispectral satellites usually contain several to dozens of bands, each band corresponds to a different spectral range, and richer spectral information of ground objects can be obtained. For example: in images taken by optical multispectral satellites, the crowns of trees have unique spectral characteristics, and the spectral responses to different bands are different. Preferably, by measuring and analyzing the spectral information of multiple different bands in the first image, the characteristic spectral lines of the target object in the first image are obtained, and the top of the target object is identified in combination with the shape, size, and texture features of the target object in the first image.

[0074] Furthermore, when the identified target object is a tree, the height of the target object is the top height of the tree canopy; when the identified target object is a building, the height of the target object is the top height of the building.

[0075] S12: Obtain the geographic coordinate range of the top area of ​​the target object.

[0076] In this embodiment, the regional distribution of the top edge of the target object is obtained from the first image data, that is, the geographic coordinate range (vector range) covered by the top area of ​​the target object. Specifically, the pixel coordinates of the edge of the top area of ​​the target object in the first image are determined. The first image data includes the geographic coordinates of the image point (0,0), so the geographic coordinates of the top edge of the target object can be determined.

[0077] S13: Acquire a second image associated with the first image, which is taken by a twilight orbit satellite on the shooting date.

[0078] The correlation means that the second image includes a preset target area, and the time interval between the shooting time of the second image and the shooting time of the first image does not exceed a preset time threshold.

[0079] In this embodiment, based on the shooting time and photographing area of ​​the first image of the optical multispectral satellite, a second image of the twilight orbit satellite that is shot at a similar time to the first image and captures the target area is acquired.

[0080] S14: According to the geographic coordinate range of the top area of ​​the target object, the top area of ​​the target object is nested in the second image, a shadow area outside the top area of ​​the target object in the second image is determined, and the geographic coordinate range of the shadow area is determined.

[0081] In this embodiment, the top area of ​​the determined target object is embedded in the second image, or in other words, according to the geographic coordinates of the top edge of the target object determined in S12, the top edge of the target object is located in the second image according to the geographic coordinates, so as to obtain the top area of ​​the regional target object in the second image; then the shadow area outside the top area of ​​the target object in the second image is determined, and the geographic coordinate range of the shadow distribution is determined. The image of the dawn-dusk orbit satellite is a full-color band image, also called dawn-dusk twilight data. The use of full-color band images can more accurately identify the shadow of the object.

[0082] S15: Determine the height of the target object according to the shooting angle when the second image is shot by the twilight orbit satellite, the solar altitude angle, and the geographical coordinate range of the shadow area.

[0083] In this embodiment, the algorithm for calculating the height of the object according to the shooting angle, the solar altitude angle, and the geographic coordinate range of the shadow area when the twilight orbit satellite takes the second image is a related algorithm in the prior art, which will not be repeated here. It is worth noting that if the target object is a tree and there is a row of trees on the roadside, the height of the target object determined in S15 is the height of the row of trees. If it is a group of trees, then the height of the edge trees of the group of trees is calculated.

[0084] Figure 2In the illustrated embodiment, by identifying the top area of ​​the object in the first image taken by the optical multispectral satellite, the top area of ​​the object in the first image is embedded in the second image taken by the dusk-dawn orbit satellite associated with it, so that the shadow area outside the top area of ​​the target object can be simply and quickly determined, thereby determining the height of the target object according to the shooting angle of the second image, the solar altitude angle, and the geographic coordinate range of the shadow area. By scheduling two different satellites, especially using the dusk-dawn orbit satellite, the shadow area can be quickly and accurately positioned, which is conducive to the rapid calculation of the height of the object.

[0085] Furthermore, before step S11, the following steps A1-A5 may also be included:

[0086] Step A1: determining the geographical location of the target area to which the target object to be measured in terms of height belongs;

[0087] In this embodiment, it is necessary to predetermine a target area (area to be photographed) including a target object whose height is to be measured. Specifically, the geographic coordinate range of the target area can be manually set.

[0088] Step A2: Determine the first moment when the sun is at its highest altitude and the second moment when the shadow of the target object is the longest within the preset shooting date relative to the preset target area.

[0089] Step A3: The optical multispectral satellite that is closest to the target area at the first moment is used as the target optical multispectral satellite, and the dawn-dusk orbit satellite that is closest to the target area at the second moment is used as the target dawn-dusk orbit satellite.

[0090] In this embodiment, the target optical multispectral satellite used to capture the first image and the target twilight orbit satellite used to capture the second image are determined by the first moment and the second moment. In the subsequent process, only the images captured by the target optical multispectral satellite and the target twilight orbit satellite need to be processed.

[0091] Step A4: Sending a photo-taking instruction to the target optical multispectral satellite and the target dawn-dusk orbit satellite.

[0092] In this embodiment, a photographing instruction may be sent to the target optical multispectral satellite and the target twilight orbit satellite at a pre-specified time within a preset photographing date, for example, a photographing instruction may be sent to the target optical multispectral satellite and the target twilight orbit satellite at 12 noon on June 1, 2024. Alternatively, a photographing instruction may be sent to the target optical multispectral satellite and the target twilight orbit satellite when the process of this method is executed for the first time, and then a number of images may be received from the target optical multispectral satellite and the target twilight orbit satellite according to their own photographing frequency.

[0093] Step A5: Receive a first image sent from a target optical multispectral satellite and a second image sent from a target dawn-dusk orbit satellite.

[0094] In this embodiment, if the target optical multispectral satellite and the target twilight orbit satellite send many images according to their own shooting frequencies, the first image taken by the target optical multispectral satellite at any time or specified time within the preset shooting date can be obtained in S11.

[0095] In this embodiment, the first moment when the sun is at its highest altitude and the second moment when the shadow of the target object is the longest within a preset shooting date are determined. The optical multispectral satellite and the target dawn-dusk orbit satellite closest to the target area at these two moments can be determined through the first moment and the second time. The satellite corresponding to the image required to be used to determine the shadow area later is accurately located, and there is no need to calculate the images of all satellites that can capture the target area. This can significantly reduce the amount of calculation in the entire method process and improve the efficiency of measuring the height of the target object.

[0096] S2: Determine the type of transmission lines within the target area.

[0097] In this embodiment, each time a new transmission line is constructed, the information of the transmission line will be stored in the power system, including but not limited to the geographical coordinates, type (types include: high-voltage transmission line, civil transmission line) and height information of the transmission line, then step S2 can match the type of the corresponding transmission line in the pre-stored information of the transmission line in the power system according to the geographical coordinates of the transmission line in the target area directly input by the user. Further, for the target area where the user does not directly input the geographical coordinates of the transmission line, the transmission line towers in the image of the target area can be identified based on the image of the target area taken by the satellite, and the geographical coordinates of each identified transmission line tower can be obtained; then, according to the geographical coordinates of the transmission line towers, the adjacent transmission line towers are connected to obtain the geographical coordinates of the transmission line between the adjacent transmission line towers; finally, according to the geographical coordinates of the transmission line, the type of the corresponding transmission line is matched in the pre-stored information of the transmission line in the power system.

[0098] For example, the user can enter the correspondence between the geographical coordinates, type and height of each transmission line in the system in advance. For example, the geographical coordinate range of a certain place can be entered in the system in advance as follows: 110°~112°25′ east longitude, 31°50′25″~32° north latitude. The type of transmission line in this area is a civil transmission line, and the installation height is 7 meters. The entered data is then stored in the system. Then, in S2, the transmission lines and their types and heights in the target area are determined according to the preset geographical coordinate range of the target area and the data of the transmission lines stored in the system.

[0099] S3: Detecting potential safety hazards between the target object and the transmission line according to the height of the target object, the type of the transmission line, and the height of the transmission line.

[0100] In the embodiment of the present invention, the height of the object is identified using satellite images, and the height of the object is combined with the height of the power transmission line to detect potential safety hazards. The specific implementation process of step S3 is described in detail below.

[0101] Figure 3 The flowchart of the implementation method of S3 when the type of the transmission line in the target area is a high-voltage transmission line specifically includes the following steps S301-S304:

[0102] S301: If the type of the transmission line in the target area is a high-voltage transmission line, determine whether the top height of the target object is lower than the high-voltage transmission line in the target area; if so, execute S302; otherwise, execute S304;

[0103] S302: Calculating a first height difference between the power transmission line in the target area and the top of the target object;

[0104] S303: Determine whether the first height difference is greater than a preset first threshold; if not, execute S304;

[0105] S304: Determine that there is a safety hazard between the target object and the power transmission line.

[0106] In this embodiment, if the transmission line in the target area is a high-voltage transmission line, the distance between the top height of the target object and the transmission line is compared with a preset first threshold. It is safe only when the top height of the object is not higher than the transmission line and the distance between the two is greater than the first threshold. Otherwise, there is a safety hazard.

[0107] Figure 4 This is a flow chart of the implementation method of S3 when the type of the power transmission line in the target area is a civil power transmission line, which specifically includes the following steps S401-S407:

[0108] S401: If the type of the power transmission line in the target area is a civil power transmission line, dispatch a drone to the target area to detect whether the target object is a tree or a building; if the target object is a tree, execute S402; if the target object is a building, execute S409;

[0109] S402: taking the height of the target object identified according to the satellite image as the top height of the tree crown, and dispatching the drone to detect the bottom height of the tree crown;

[0110] S403: Determine whether the top height of the tree canopy is lower than the civil power transmission line in the target area; if so, execute S404; otherwise, execute S406;

[0111] S404: Calculating a second height difference between the top of the tree canopy and the civil power transmission line in the target area;

[0112] S405: Determine whether the second height difference is greater than a preset second threshold, if not, execute S412;

[0113] S406: Determine whether the bottom height of the tree crown is higher than the civil power transmission line in the target area; if so, execute S407, otherwise execute S412;

[0114] S407: Calculating a third height difference between the bottom of the tree canopy and the civil power transmission line in the target area;

[0115] S408: Determine whether the third height difference is greater than a preset third threshold, if not, execute S412;

[0116] S409: Determine whether the height of the building is higher than the civil power transmission line in the target area; if so, execute S410;

[0117] S410: dispatching a drone to the target area to detect the lateral distance between the side of the building and the civil power transmission line;

[0118] S411: Determine whether the lateral distance between the side of the building and the civil power transmission line is greater than a preset fourth threshold, if not, execute S412;
