Therefore, it is necessary to monitor the operating status and on-site environment of the overhead transmission line to give timely warnings before an accident occurs. One of the threat factors that may cause an accident is construction machinery, because construction machinery can extend into the channel of the overhead transmission line and may touch the high-voltage transmission line, which may lead to a tripping accident.

[0003] However, the current method of monitoring construction machinery at transmission lines can only distinguish the position of construction machinery in a two-dimensional image, but cannot measure whether the construction machinery poses a threat to the transmission lines, resulting in frequent false alarms in actual applications and increasing manual troubleshooting costs. Summary of the invention

[0012] The identification module is configured to: when it is determined that there is a construction machine in the monitored area, obtain the current highest point image coordinates of the highest point in the construction machine according to the image data;

[0013] The acquisition module is configured to: acquire a grid warning map matching the weather information from a pre-stored map library according to the currently collected weather information of the monitored area; the grid warning map is a grid map of the area where the protection channel is located, and the grid warning map is marked with a warning area; the minimum height of the warning area in different grid warning maps is different;

[0014] The warning module is configured to issue a warning message when the current highest point image coordinates are in the warning area in the grid warning map.

[0017] Compared with the prior art, the present invention has at least the following beneficial effects:

[0018] The embodiments of the present invention provide an early warning method, device, equipment and storage medium for construction machinery at a transmission line. On the one hand, by monitoring the position of the construction machinery in the monitored area and locating it to the highest point of the construction machinery, the most threatening part of the construction machinery to the transmission line can be accurately located; on the other hand, by obtaining the corresponding grid early warning map according to the weather conditions in the monitored area, and the minimum heights of the early warning areas in different grid early warning maps are different, it can be seen that the grid early warning map is matched with the weather; then, by combining the most threatening part of the construction machinery with the grid early warning map under the current weather, it is determined that when the most threatening part of the construction machinery is in the early warning area of ​​the grid early warning map under the current weather, an alarm is issued.

[0026] In order to at least solve the technical problem of low alarm accuracy of construction machinery at transmission lines in related technologies, an embodiment of the present invention provides an early warning method for construction machinery at transmission lines. The basic inventive concept is: on the one hand, by monitoring the position of construction machinery in the monitored area and locating it to the highest point of the construction machinery, the most threatening part of the construction machinery to the transmission line can be accurately located; on the other hand, by obtaining the corresponding grid early warning map according to the weather conditions in the monitored area, and the minimum height of the warning area in different grid early warning maps is different, it can be seen that the grid early warning map is matched with the weather; then, by combining the most threatening part of the construction machinery and the grid early warning map under the current weather, it is determined that when the most threatening part of the construction machinery is in the warning area of ​​the grid early warning map under the current weather, an alarm is issued. Therefore, through the grid warning map and the highest point of the construction machinery, it is possible to accurately judge whether the construction machinery poses a threat to the transmission line. In actual applications, false alarms will not occur frequently. Moreover, by combining weather information to select a matching grid warning map to judge the dangerous situation of the construction machinery, it is possible to make a more accurate judgment on the threat level of the construction machinery. This can avoid using the same judgment standard to judge the threat level of the construction machinery in different weather conditions, which may lead to safety accidents caused by the judgment result of no threat when the construction machinery has actually posed a threat to the transmission line, and it is also impossible to issue timely warnings for safety accidents that have occurred.

[0027] The following is a more specific description of the early warning method for construction machinery at a transmission line according to an embodiment of the present invention, but the present invention should not be limited thereto.

[0028] The early warning method for construction machinery at the transmission line provided by the embodiment of the present invention can be applied to a video surveillance device, which can be deployed in an electric power scenario to monitor the area where the protection channel of the transmission line is located and process the images collected under monitoring to monitor the threat level of the construction machinery, and when it is determined that the construction machinery has a high threat risk, timely send an alarm message to the monitoring center or related user terminals to achieve a safety early warning. Of course, the early warning method for construction machinery at the transmission line provided by the embodiment of the present invention can also be applied to a monitoring center that is separated from the video surveillance device but has a communication connection. The monitoring center can receive the image data sent by the video surveillance device, and by executing the early warning method for construction machinery at the transmission line provided by the embodiment of the present invention, process the image data to monitor the threat level of the construction machinery, and when it is determined that the construction machinery has a high threat risk, timely send an alarm or send the alarm message to the related user terminal to achieve a safety early warning.

[0029] See also Figure 1 , Figure 1 The present invention is a flowchart of an early warning method for construction machinery at a transmission line according to an exemplary embodiment of the present invention; the early warning method for construction machinery at a transmission line comprises:

[0030] In step S100, based on the currently collected image data of the monitored area, it is determined whether there is a construction machine in the monitored area; the monitored area includes the area where the protection channel of the transmission line is located;

[0031] In step S200, when it is determined that there is a construction machine in the monitored area, the current highest point image coordinates of the highest point in the construction machine are obtained according to the image data;

[0032] In step S300, according to the currently collected weather information of the monitored area, a grid warning map matching the weather information is obtained from a pre-stored map library; the grid warning map is a grid map of the area where the protection channel is located, and the grid warning map is marked with a warning area; the minimum height of the warning area in different grid warning maps is different;

[0033] In step S400, when the current highest point image coordinates are in the warning area in the grid warning map, an alarm message is issued.

[0034] In the power scenario, the image data of the monitored area can be obtained in a scheduled or real-time manner through the video surveillance equipment deployed at the transmission line. The monitored area may refer to the area within the visible range of the video surveillance equipment, which includes the area where the protection channel of the transmission line is located. For the relevant definition of the protection channel of the transmission line, please refer to the relevant technology. In this way, the image data of the monitored area can be obtained. Subsequently, step S100 can be executed to determine whether there is construction machinery in the monitored area based on the currently collected image data, wherein the AI ​​intelligent algorithm in the relevant technology can be used to identify whether there is construction machinery in the monitored area based on the image data. It will not be explained in detail here. The construction machinery may include but is not limited to: cranes, tower cranes, excavators, bulldozers, loaders, concrete mixers, aerial work vehicles, live work vehicles, wire racks, etc.

[0035] When it is determined through step S100 that there is no construction machinery in the monitored area, it is considered that there is no threat to the transmission line caused by the construction machinery, and there is no need to issue an alarm message. However, when it is determined that there is construction machinery in the monitored area, step S200 will be executed to further process the image data. For example, the edge information of the construction machinery can be extracted by using the AI ​​intelligent algorithm in the relevant technology, and then the highest point of the construction machinery can be found from the height direction, and the image coordinates at the highest point are obtained, that is, the image coordinates of the current highest point are obtained.

[0036] Regardless of the execution order of step S200, when it is determined that there is construction machinery in the monitored area, step S300 will also be executed to further obtain the current weather information of the monitored area through weather sensors deployed in the monitored area, such as rain sensors, wind speed sensors, fog sensors, etc., and then obtain a grid warning map matching the current weather information from a pre-stored map library. In some embodiments, a grid warning map corresponding to the safety distance can be constructed based on the characteristic that the safety distance between the construction machinery and the transmission line changes at any time under different weather conditions. The safety distance can be understood as the safety distance between the highest point of the construction machinery and the transmission line. Therefore, the minimum height of the warning area in the grid warning map under different weather conditions can be adjusted according to the safety distance.

[0037] In order to further improve the effectiveness of the grid warning map, the safety of the transmission line, and the timeliness of the warning, in some embodiments, the warning method for construction machinery at the transmission line provided by the embodiment of the present invention also provides a solution for building a map library. Based on this, the embodiment of the present invention first divides different weather conditions to configure the threat level that matches the weather information for the subsequent grid warning map. In the embodiment of the present invention, the weather information is divided into three levels, that is, the weather information includes the first weather information used to characterize the current weather as rainy, foggy, snowy, or hail, the second weather information used to characterize the current weather as strong wind, thunder, high temperature, or low temperature, and the third weather information used to characterize the current weather as other weather other than the weather represented by the first weather information and the second weather information. Based on this, the construction process of the map library includes:

[0038] In step S011, a bounding box of the area where the protection channel of the power transmission line is located is generated according to the image data of the monitored area;

[0039] In step S012, the enclosing frame is divided into a plurality of sub-areas with different heights by moving a first plane parallel to the transmission line along the height direction of the enclosing frame, thereby obtaining a protection channel map;

[0040] In step S013, a sub-area of ​​the first set height range in the protection channel map is used as a warning area to obtain a grid warning map corresponding to the first weather information;

[0041] In step S014, a sub-area of ​​the second set height range in the protection channel is used as a warning area to obtain a grid warning map corresponding to the second weather information;

[0042] In step S015, a sub-area of ​​the third set height range in the protection channel is used as a warning area, and a grid warning map corresponding to the third weather information is obtained;

[0043] In step S016, all grid warning maps and the corresponding relationship between all grid warning maps and weather information are stored in a database to obtain the map library;

[0044] The lowest height of the second set height range is lower than the lowest height of the first set height range and higher than the highest height of the third set height range.

[0045] Therefore, through steps S011 to S016, the threat level between construction machinery and power transmission lines can be graded according to the severity of the weather. Because, from the definition of the above weather information, it can be seen that the severity of the above three weather information is as follows: the first weather information is higher than the second weather information, and the second weather information is higher than the third weather information. In the grid warning map constructed based on the above three types of weather information, the lowest height of the warning area in the grid warning map corresponding to the first weather information is lower than the lowest height of the warning area in the grid warning map corresponding to the second weather information, and the lowest height of the warning area in the grid warning map corresponding to the second weather information is lower than the lowest height of the warning area in the grid warning map corresponding to the third weather information. It can be seen that in the grid warning map corresponding to the first weather information, the height that the highest point of the construction machinery can reach without triggering the alarm is the lowest, and the second weather information follows. In this way, the timeliness and accuracy of the alarm in different weather conditions can be guaranteed.

[0046] The above-mentioned various set height ranges can be set based on experience or experiments.

[0047] On the basis of any of the above embodiments, in order to further improve the effectiveness of the warning and reduce the possibility of accidents, in some embodiments, the warning area can be further divided into multiple warning sub-areas, so as to use multiple warning sub-areas to further determine the threat level of the construction machinery, that is, the warning area includes multiple warning sub-areas with different heights, and different warning sub-areas correspond to different warning frequencies, and the warning frequency is positively correlated with the height corresponding to the warning area. Accordingly, in step S400, when the current highest point image coordinates are in the warning area in the grid warning map, the step of issuing the warning information may include:

[0048] In step S410, when the current highest point image coordinates are in the warning area in the grid warning map, determining the target warning sub-area where the current highest point image coordinates are located;

[0049] In step S420, an alarm message is issued within a first set time period at a first target warning frequency corresponding to the target warning sub-area.

[0050] Therefore, when the construction machinery is in a higher warning sub-area, the alarm will be issued at a higher frequency. This alarm method can strengthen the alarm intensity when the threat level is higher, so that relevant personnel can pay more attention to the threat of construction machinery to the transmission line, which is conducive to reducing the possibility of safety accidents.

[0051] In addition, in some other embodiments, the warning area can be further divided into multiple warning sub-areas according to the type of construction machinery to avoid invalid alarms, which is conducive to reducing the cost of manpower investigation. At this time, the warning area can also include multiple warning sub-areas of different heights, and different warning sub-areas correspond to different types of machinery; the machinery types include a first type of construction machinery with insulating materials at the highest point, and a second type of construction machinery with conductive materials at the highest point; the lowest height of the warning sub-area corresponding to the first type is greater than the lowest height of the warning sub-area corresponding to the second type.

[0052] Accordingly, before step S400, that is, when the current highest point image coordinates are in the warning area in the grid warning map, before the step of issuing an alarm message, the early warning method for construction machinery at a power transmission line provided by an embodiment of the present invention may further include:

[0053] In step S0411, the target machine type at the highest point of the construction machine is determined according to the image data;

[0054] In step S0412, the lowest height value of the warning sub-area corresponding to the target machine type is obtained from the grid warning map;

[0055] In step S0413, when the height value of the current highest point image coordinates is greater than or equal to the minimum height value, it is determined that the current highest point image coordinates are in the warning area in the grid warning map.

[0056] It is understandable that step S0411 can be performed separately from step S200, or they can be performed together. For example, when using an AI algorithm to identify the highest point in a construction machine, in addition to outputting the current highest point image coordinates of the highest point, the highest point can also be identified by type to identify whether the material of the highest point is an insulating material or a conductive material. Since the shapes or colors of conductive materials and insulating materials may be different, when training the relevant AI algorithm, the shape contour or color features of the highest point can be marked so that the AI ​​algorithm can distinguish the type of the highest point. In addition, the type of construction machinery can also be directly identified, because some construction machinery generally has an insulating layer or a conductive layer at its highest point due to design standards. Therefore, when training the relevant AI algorithm, the type of construction machinery can be marked to identify whether the construction machinery is the first type or the second type mentioned above.

[0057] Therefore, through steps S0411 to S0413, even if the highest point of the construction machinery falls into the warning area, there will be no direct alarm. Instead, the type of the construction machinery is first determined, and then based on the type of the construction machinery and the image coordinates at the highest point, it is determined whether the construction machinery poses a threat to the transmission line. In short, only when the highest point of the construction machinery is higher than or equal to the lowest height of the warning sub-area corresponding to the type of construction machinery, the construction machinery is considered to be a threat, and the current highest point image coordinates are determined to be in the warning area in the grid warning map, and then step S400 is executed to issue an alarm message.

[0058] On the contrary, when the highest point of the construction machinery is lower than the lowest height of the warning sub-area corresponding to the type of the construction machinery, it is considered that the construction machinery does not pose a threat, and it is determined that the current highest point image coordinates are not in the warning area of ​​the grid warning map, and step S400 is not executed, and no alarm is required. That is, based on the above embodiment, before step S400, the early warning method for construction machinery at the transmission line provided by the embodiment of the present invention may also include:

[0059] In step S044, when the height value of the current highest point image coordinate is less than the minimum height value, it is determined that the current highest point image coordinate is not in the warning area in the grid warning map.

[0060] In addition, in practice, although the highest point of the construction machinery is in the warning area, it may not continue to rise, but descend. If an alarm is also sounded at this time, interference may occur. Therefore, in order to solve this technical problem, in some embodiments, the embodiments of the present invention also make corresponding adjustments to the alarm logic, that is, before step S400, the early warning method for construction machinery at the transmission line provided by the embodiments of the present invention may also include:

[0061] In step S0421, a height change curve of the highest point in the construction machinery is constructed based on a plurality of historical highest point image coordinates within a second set time period before the current time and the current highest point image coordinates;

[0062] In step S0422, the movement trend and movement speed of the highest point in the construction machinery are determined according to the height change curve;

[0063] Accordingly, in the above step S400, when the current highest point image coordinates are in the warning area in the grid warning map, the step of issuing a warning message is adjusted to:

[0064] When the image coordinates of the current highest point are in the warning area of ​​the grid warning map and the movement trend indicates that the height of the highest point in the construction machinery is on an upward trend, the warning frequency corresponding to the movement speed is obtained from the pre-stored mapping relationship, and an alarm message is issued at the warning frequency within a first set time period.

[0065] That is to say, before executing step S400, the movement of the highest point in the construction machinery can be determined through steps S0421 and S0422. In step S0421, time can be used as an independent variable, and multiple historical highest point image coordinates and current highest point image coordinates can be used as dependent variables. The corresponding height change curve can be obtained by fitting based on time points and coordinate points in chronological order. The curve fitting principle can be found in the relevant technology. Then, the movement trend and movement speed of the highest point can be determined based on the height change curve. The determination principle of the movement trend and movement speed can be found in the relevant technology, which will not be described in detail here.

[0066] After obtaining the movement trend and movement speed of the highest point of the construction machinery, the adjusted step S400 can be executed, that is, when the current highest point image coordinates are in the warning area in the grid warning map, and the movement trend indicates that the height of the highest point in the construction machinery is on an upward trend, the warning frequency corresponding to the movement speed is obtained from the pre-stored mapping relationship, and an alarm message is issued at the warning frequency within the first set time period.

[0067] When the solution in the previous embodiment is applied to the embodiment shown in the above steps S410 to S420, there will be a conflict between the two warning frequencies. To resolve this conflict, in some embodiments, the embodiment of the present invention makes corresponding adjustments to step S410, that is, when the current highest point image coordinates are in the warning area in the grid warning map, the step of determining the target warning sub-area where the current highest point image coordinates are located is adjusted to:

[0068] When the current highest point image coordinates are in the warning area in the grid warning map, and the movement trend indicates that the height of the highest point in the construction machinery is on the rise, the target warning sub-area where the current highest point image coordinates are located is determined, and the second target warning frequency corresponding to the movement speed is obtained from the pre-stored mapping relationship, and the target warning frequency is calculated based on the first target warning frequency and the second target warning frequency. The first target warning frequency and the second target warning frequency can be averaged or weighted averaged to obtain the target warning frequency.

[0069] Accordingly, step S420 is adjusted to: the step of issuing an alarm message within a first set time period at the first target warning frequency corresponding to the target warning sub-area is adjusted to:

[0070] An alarm message is issued within a first set time period at the target warning frequency.

[0071] In the above-mentioned related embodiments, the mapping relationship stores the warning frequencies corresponding to different motion speed ranges. The mapping relationship can be set according to experience or experiments, and the first set duration can also be set according to experience or experiments.

[0072] It is worth noting that the embodiments or technical features of the early warning method for construction machinery at the transmission line provided by the present invention can be combined with each other to form a new technical solution as long as there is no combination contradiction.

[0073] Corresponding to the above-mentioned embodiment of the early warning method for construction machinery at a transmission line, the embodiment of the present invention further provides an early warning device for construction machinery at a transmission line, such as Figure 2 As shown, Figure 2 1 is a structural block diagram of an early warning device for construction machinery at a power transmission line according to an exemplary embodiment of the present invention. The early warning device 200 for construction machinery at a power transmission line may include:

[0074] The determination module 210 is configured to: determine whether there is a construction machine in the monitored area according to the currently collected image data of the monitored area; the monitored area includes the area where the protection channel of the transmission line is located;

[0075] The identification module 220 is configured to: when it is determined that there is a construction machine in the monitored area, obtain the current highest point image coordinates of the highest point in the construction machine according to the image data;

[0076] The acquisition module 230 is configured to: acquire a grid warning map matching the weather information from a pre-stored map library according to the currently collected weather information of the monitored area; the grid warning map is a grid map of the area where the protection channel is located, and the grid warning map is marked with a warning area; the minimum height of the warning area in different grid warning maps is different;

[0077] The warning module 240 is configured to issue a warning message when the current highest point image coordinates are in the warning area in the grid warning map.

[0078] In some embodiments, the weather information includes first weather information for characterizing that the current weather is rainy, foggy, snowy, or hail-like, second weather information for characterizing that the current weather is strong wind, thunder and lightning, high temperature, or low temperature, and third weather information for characterizing that the current weather is other weather other than the weather represented by the first weather information and the second weather information.

[0079] Accordingly, the early warning device 200 for construction machinery at the power transmission line may also include:

[0080] A construction module is configured to: generate a bounding box of the area where the protection channel of the transmission line is located according to the image data of the monitored area;

[0081] By moving a first plane parallel to the transmission line along the height direction of the enclosing frame, the enclosing frame is divided into a plurality of sub-areas with different heights, thereby obtaining a protection channel map;

[0082] Taking the sub-area of ​​the first set height range in the protection channel map as the warning area, and obtaining a grid warning map corresponding to the first weather information;

[0083] Taking the sub-area of ​​the second set height range in the protection channel as the warning area, and obtaining a grid warning map corresponding to the second weather information;

[0084] Taking a sub-area of ​​a third set height range in the protection channel as a warning area, and obtaining a grid warning map corresponding to the third weather information;

[0085] storing all grid warning maps and the corresponding relationship between all grid warning maps and weather information in a database to obtain the map library;

[0086] The lowest height of the second set height range is lower than the lowest height of the first set height range and higher than the highest height of the third set height range.

[0087] In some embodiments, the warning area includes a plurality of warning sub-areas of different heights, and different warning sub-areas correspond to different warning frequencies, and the warning frequency is positively correlated with the height corresponding to the warning area. Accordingly, when the current highest point image coordinates are in the warning area in the grid warning map, the process of issuing the warning information by the alarm module 240 is configured as follows:

[0088] When the current highest point image coordinates are in the warning area in the grid warning map, determining the target warning sub-area where the current highest point image coordinates are located;

[0089] An alarm message is issued within a first set time period at a first target warning frequency corresponding to the target warning sub-area.

[0090] In some embodiments, the warning area includes multiple warning sub-areas of different heights, and different warning sub-areas correspond to different machine types; the machine types include a first type in which the highest point of the construction machinery is an insulating material, and a second type in which the highest point of the construction machinery is a conductive material; the lowest height of the warning sub-area corresponding to the first type is greater than the lowest height of the warning sub-area corresponding to the second type.

[0091] Correspondingly, when the current highest point image coordinates are in the warning area in the grid warning map, the warning module 240 is further configured to:

[0092] determining the target machine type at the highest point of the construction machine according to the image data;

[0093] Acquire the lowest altitude value of the warning sub-area corresponding to the target machine type from the grid warning map;

[0094] When the height value of the current highest point image coordinate is greater than or equal to the minimum height value, it is determined that the current highest point image coordinate is in the warning area in the grid warning map.

[0095] In some embodiments, when the current highest point image coordinates are in the warning area in the grid warning map, the warning module 240 is further configured to:
