Description

Technical Field

[0001] This application relates to the field of remote monitoring technology, specifically to a method, device, medium, and electronic equipment for remote monitoring of tower cranes. Background Technology

[0002] A tower crane, also known as a tower hoist, originated in Western Europe and is a rotating crane with its boom mounted on a tall tower. It offers a large working space and is primarily used in building construction for the vertical and horizontal transport of materials and the installation of building components. With the rapid development of internet technology and the emergence of high-precision cameras, monitoring personnel can remotely monitor the operation of tower cranes by viewing split-screen videos of various monitored parts on a monitoring display screen. This allows for better monitoring of tower crane operations and helps prevent safety accidents.

[0003] However, when there are many video monitoring sections for tower cranes and many monitoring videos displayed on the monitoring screen, it is difficult for personnel to quickly identify potential safety hazards in tower cranes from among the numerous monitoring videos, which increases the probability of safety accidents involving tower cranes. Summary of the Invention

[0004] To make it easier for personnel to identify potential safety hazards in tower cranes from numerous surveillance videos, this application provides a method, device, medium, and electronic equipment for remote monitoring of tower cranes.

[0005] The first aspect of this application provides a method for remote monitoring of a tower crane, specifically including:

[0006] The real-time monitoring videos of each monitored part of the tower crane are acquired when the tower crane is in operation, and each real-time monitoring video is displayed on the monitoring screen in a split screen.

[0007] Obtain the influencing factors of the safe operation of the tower crane, and determine the monitored parts associated with the influencing factors;

[0008] Based on the aforementioned influencing factors, the real-time monitoring video corresponding to the associated monitored location is displayed in full screen to enable monitoring personnel to identify potential safety hazards of the tower crane.

[0009] By adopting the above technical solution, real-time monitoring videos of various monitored parts of the tower crane are acquired during operation. Then, the influencing factors affecting the safe operation of the tower crane, i.e., unsafe factors, are identified. Based on these influencing factors, the associated monitored parts of the tower crane are determined. After determining the influencing factors and associated monitored parts, the real-time monitoring videos of the associated monitored parts are retrieved from the real-time monitoring videos of each monitored part of the tower crane. The display of these videos on the monitoring screen is adjusted, prioritizing full-screen display of these videos for a preset duration before reverting to the normal split-screen display state. This allows personnel to intuitively determine whether there are safety hazards in the corresponding parts of the tower crane during the full-screen display phase of the real-time monitoring videos corresponding to unsafe factors. This makes it easier for personnel to identify potential safety hazards in the tower crane from numerous monitoring videos, reducing the probability of tower crane accidents.

[0010] Optionally, obtaining the influencing factors of the safe operation of the tower crane and determining the monitored parts associated with the influencing factors includes:

[0011] The number of non-standard operations by the operator of the tower crane within a first preset time period is obtained;

[0012] The number of non-standard operations is compared with a threshold number. If the number of non-standard operations is less than the threshold number, the next influencing factor for the safe operation of the tower crane is obtained.

[0013] If the number of non-standard operations is not less than the number threshold, then the non-standard operation is determined to be an influencing factor on the safe operation of the tower crane, and the operator's cab of the tower crane is determined to be the monitored part associated with the influencing factor.

[0014] Based on the aforementioned influencing factor, the real-time monitoring video corresponding to the associated monitored area is displayed in full screen, including:

[0015] Based on the aforementioned influencing factor, the real-time monitoring video corresponding to the operator's cab of the tower crane is displayed in full screen for a second preset time.

[0016] After the second preset time, each of the real-time monitoring videos is displayed in a split-screen format.

[0017] By employing the aforementioned technical solution, the number of non-standard operations by the tower crane operator within a first preset time period is compared with a threshold. If the number of non-standard operations is greater than or equal to the threshold, it indicates a high number of non-standard operations by the operator within the first preset time period, suggesting a higher probability of operator error. The operator's non-standard operations are then identified as an influencing factor, and the tower crane's cab is designated as the associated monitored area. Finally, the real-time monitoring video of the tower crane's cab is displayed in full screen for a second preset time period, allowing personnel to intuitively and accurately determine the existence of safety hazards through the full-screen display. After the second preset time, normal operation resumes with split-screen display of the various real-time monitoring videos, making it easier for personnel to identify potential safety hazards in the tower crane from among numerous real-time monitoring videos.

[0018] Optionally, obtaining the influencing factors of the safe operation of the tower crane and determining the monitored parts associated with the influencing factors includes:

[0019] The slewing angle of the tower crane is obtained through a preset slewing sensor;

[0020] If the rotation angle is not greater than the angle threshold, then continue to obtain the next influencing factor for the safe operation of the tower crane;

[0021] If the slewing angle is greater than the angle threshold, then the slewing angle is determined to be an influencing factor for the safe operation of the tower crane, and the slewing table of the tower crane is determined to be the monitored part associated with the influencing factor.

[0022] Based on the aforementioned influencing factor, the real-time monitoring video corresponding to the associated monitored area is displayed in full screen, including:

[0023] Based on the aforementioned influencing factor, the real-time monitoring video corresponding to the slewing platform of the tower crane is displayed in full screen for a third preset time.

[0024] After the third preset time, each of the real-time monitoring videos is displayed in a split-screen format.

[0025] By adopting the above technical solution, the obtained slewing angle of the tower crane is compared with the angle threshold. If the slewing angle is greater than the angle threshold, it indicates that the slewing angle of the tower crane is too large, and the tower crane is prone to cable twisting and damage. Therefore, the slewing angle is determined as an influencing factor, and the slewing platform of the tower crane is regarded as the associated monitored part. Finally, the real-time monitoring video of the tower crane's slewing platform is prioritized for full-screen display for a third preset time, so that personnel can intuitively and accurately determine whether there are any safety hazards through the full-screen display of real-time monitoring video. After the third preset time, normal split-screen display of each real-time monitoring video is restored, making it easier for personnel to identify the safety hazards of the tower crane from a large number of real-time monitoring videos.

[0026] Optionally, obtaining the influencing factors of the safe operation of the tower crane and determining the monitored parts associated with the influencing factors includes:

[0027] The visibility of the tower crane within a preset range is obtained using a visibility sensor;

[0028] If the visibility is greater than the visibility threshold, then continue to obtain the next influencing factor for the safe operation of the tower crane;

[0029] If the visibility is not greater than the visibility threshold, then the visibility is determined to be an influencing factor for the safe operation of the tower crane, and the hook of the tower crane is determined to be the monitored part associated with the influencing factor.

[0030] Based on the aforementioned influencing factor, the real-time monitoring video corresponding to the associated monitored area is displayed in full screen, including:

[0031] Based on the aforementioned influencing factor, the real-time monitoring video corresponding to the hook of the tower crane is displayed in full screen for a fourth preset time.

[0032] After the fourth preset time, each of the real-time monitoring videos is displayed in a split-screen format.

[0033] By adopting the above technical solution, the visibility within the preset range of the tower crane is compared with the visibility threshold. If the visibility is greater than the visibility threshold, it indicates that the visibility of the tower crane's operating environment is relatively high and will not affect the safe operation of the tower crane. If the visibility is less than or equal to the visibility threshold, it indicates that the visibility of the tower crane's operating environment is low, which may affect the operator's field of vision. Then, visibility is determined as an influencing factor for the safe operation of the tower crane, and the hook of the tower crane is regarded as the associated monitored part. Finally, the real-time monitoring video of the tower crane's hook is prioritized for full-screen display for a fourth preset time, so that personnel can intuitively and accurately determine whether there are any safety hazards during the operation of the hook through the full-screen real-time monitoring video. After the fourth preset time, the real-time monitoring videos are displayed in split screens, making it easier for personnel to identify the safety hazards of the tower crane from a large number of real-time monitoring videos.

[0034] Optionally, the step of displaying the real-time monitoring video corresponding to the associated monitored part in full screen according to the influencing factor, so as to enable monitoring personnel to identify the safety hazards of the tower crane, includes:

[0035] The impact factors are assessed for risk levels to obtain their levels.

[0036] Based on the impact factor level, the full-screen display time of the real-time monitoring video corresponding to the associated monitored part is determined. The higher the impact factor level, the longer the full-screen display time.

[0037] After the real-time monitoring video corresponding to the associated monitored part is displayed in full screen, each of the real-time monitoring videos is displayed in split screen so that the monitoring personnel can identify the safety hazards of the tower crane.

[0038] By adopting the above technical solution, after determining the influencing factors for the safe operation of tower cranes, a risk level assessment is performed on these factors. The safety risk posed by each factor to the tower crane is quantified, resulting in an influencing factor level. A higher influencing factor level indicates a greater safety risk to the tower crane. Next, based on the influencing factor level, the full-screen display time of the real-time monitoring video of the associated monitored area is determined. A higher influencing factor level indicates a greater safety risk to the tower crane, requiring personnel to observe the monitoring video for an extended period to determine if any safety hazards exist in the associated monitored areas. Therefore, the longer the real-time monitoring video of the associated monitored area is displayed in full screen on the monitoring screen, the better. After full-screen display, the real-time monitoring video of each monitored area is displayed in split-screen mode, making it easier for personnel to identify potential safety hazards in the tower crane from numerous real-time monitoring videos.

[0039] Optionally, after determining the full-screen display time of the real-time monitoring video corresponding to the associated monitored area based on the influence factor level, the method further includes:

[0040] Determine whether there are multiple impact factor levels. If there are multiple impact factor levels, determine the order in which the real-time monitoring videos are displayed in full screen according to each impact factor level. The higher the impact factor level, the earlier the real-time monitoring videos are displayed in full screen.

[0041] By adopting the above technical solution, if there are multiple identified impact factor levels, it means that there are also multiple impact factors on the safe operation of tower cranes. The real-time monitoring video of the monitored part associated with each impact factor is given priority for full-screen display. Then, the order of full-screen display of the real-time monitoring video of the monitored part associated with each impact factor is determined according to the size of each impact factor level. The larger the impact factor level, the longer the full-screen display is given priority, so that the safety hazards corresponding to the impact factors with higher safety risks are not easily missed.

[0042] Optionally, the method further includes:

[0043] Count the frequency of occurrence of the influencing factors within a preset time period before the current moment;

[0044] Based on the frequency of occurrence, the position of the real-time monitoring video corresponding to the monitored part associated with the influencing factor in the split-screen display is adjusted so that the monitoring personnel can identify the safety hazards of the tower crane. The higher the frequency of occurrence, the closer the position in the split-screen display is to the central area.

[0045] By adopting the above technical solution, after determining the influencing factors for the safe operation of tower cranes, the frequency of occurrence of these influencing factors within a preset time period before the current time is used. The higher the frequency of occurrence, the greater the probability of the safety hazard corresponding to this influencing factor. Therefore, the real-time monitoring video of the monitored part associated with this influencing factor is focused on monitoring, and the position of this real-time monitoring video in the split-screen display is adjusted to a position closer to the center area, which conforms to the viewing habits of personnel watching the monitoring display screen, thereby making it easier for personnel to identify safety hazards of tower cranes.

[0046] A second aspect of this application provides a remote monitoring device for tower cranes, specifically comprising:

[0047] The monitoring video acquisition module is used to acquire real-time monitoring videos of each monitored part when the tower crane is in operation, and each real-time monitoring video is displayed on the monitoring display screen in a split screen.

[0048] The influencing factor acquisition module is used to acquire the influencing factors of the safe operation of the tower crane and determine the monitored parts associated with the influencing factors.

[0049] The monitoring display adjustment module is used to display the real-time monitoring video corresponding to the associated monitored part in full screen according to the influencing factor, so that the monitoring personnel can identify the safety hazards of the tower crane.

[0050] By adopting the above technical solution, the monitoring video acquisition module acquires real-time monitoring videos of each monitored part when the tower crane is in operation. Then, the influence factor acquisition module acquires the influence factors of the safe operation of the tower crane and determines the associated monitored parts based on the acquired influence factors. Finally, the monitoring display adjustment module prioritizes full-screen display of the real-time monitoring videos of the monitored parts associated with the influence factors on the tower crane. After full-screen display, the split-screen display of each real-time monitoring video is restored, thereby enabling personnel to identify safety hazards of the tower crane from numerous real-time monitoring videos.

[0051] In summary, this application includes at least one of the following beneficial technical effects:

[0052] After identifying the influencing factors and associated monitored parts of the tower crane's safe operation, the associated real-time monitoring videos are retrieved from the real-time monitoring videos of each monitored part of the tower crane. The display of these videos on the monitoring screen is then adjusted, prioritizing full-screen display of these videos for a specific duration before reverting to the normal split-screen display of all real-time monitoring videos. This allows personnel to intuitively determine whether there are safety hazards in the corresponding parts of the tower crane during the full-screen display phase of the real-time monitoring videos corresponding to unsafe factors. Consequently, it makes it easier for personnel to identify potential safety hazards in the tower crane from numerous monitoring videos, reducing the probability of safety accidents involving the tower crane.

[0060] To enable those skilled in the art to better understand the technical solutions in this specification, the technical solutions in the embodiments of this specification will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0061] In the description of the embodiments in this application, words such as "illustrative," "for example," or "for example" are used to indicate examples, illustrations, or explanations. Any embodiment or design described as "illustrative," "for example," or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or designs. Rather, the use of words such as "illustrative," "for example," or "for example" is intended to present the relevant concepts in a specific manner.

[0062] In the description of the embodiments of this application, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, B existing alone, or A and B existing simultaneously. Furthermore, unless otherwise stated, the term "multiple" means two or more. For example, multiple systems refer to two or more systems, and multiple screen terminals refer to two or more screen terminals. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the indicated technical features. Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. The terms "comprising," "including," "having," and their variations all mean "including but not limited to," unless otherwise specifically emphasized.

[0063] See Figure 1 This application discloses a flowchart of a remote monitoring method for tower cranes, which can be implemented using a computer program or run on a remote monitoring device for tower cranes based on the von Neumann architecture. The computer program can be integrated into an application or run as a standalone utility application, specifically including:

[0064] S101: Acquire real-time monitoring videos of each monitored part when the tower crane is in operation, and display each real-time monitoring video in a split screen on the monitoring display screen.

[0065] Specifically, "tower crane in working state" refers to the tower crane operator using the tower crane to vertically transport materials and install components during the construction of multi-story and high-rise buildings. "Monitored parts" refers to the parts of the tower crane equipped with cameras for video monitoring. In this embodiment, the monitored parts may be the tower crane's cab, slewing platform, hook, etc.; in other embodiments, they may be the tower crane's boom.

[0066] Real-time monitoring videos of each monitored part of the tower crane are acquired by cameras installed at various monitored locations. These videos are then displayed in a split-screen format on a monitoring screen in the control room, allowing personnel to better monitor the tower crane's operational status through these individual videos. The monitoring screen can be an LCD monitor; in other embodiments, an LCD video wall can also be used. Split-screen display of real-time monitoring videos refers to displaying multiple real-time monitoring videos simultaneously on a single monitoring screen. The implementation is briefly described below: A typical monitoring screen system consists of three parts: a front-end monitoring unit responsible for capturing images; a back-end monitoring screen responsible for outputting and displaying the images; and a central control system responsible for processing the images transmitted from the front end and switching them to the monitoring screen for display. Decoders and image processors are commonly used to achieve the function of displaying multiple images simultaneously on a single monitoring screen. These are existing technologies and will not be elaborated further.

[0067] It should be noted that the monitored part of the tower crane and the real-time monitoring video have a one-to-one correspondence. In other embodiments, the monitored part and the real-time monitoring video can also have a one-to-many relationship. For example, if two cameras (with different shooting angles) are installed on the monitored part A, then there are two real-time monitoring videos displayed on the monitoring screen that correspond to the monitored part A.

[0068] S102: Obtain the influencing factors of the safe operation of tower cranes and determine the monitored parts associated with the influencing factors.

[0069] Specifically, influencing factors can be understood as factors that cause safety hazards in tower cranes, leading to their unsafe operation. These factors can exist within the tower crane itself or be related to natural factors. It's important to note that influencing factors are not the same as safety hazards, but rather factors that induce safety hazards in tower cranes. Visibility within a preset range for the tower crane can be obtained using visibility sensors. If visibility is below a visibility threshold, it indicates that the current environmental visibility is lower than normal, potentially affecting the operator's hook operation and causing safety hazards during tower crane operation. Therefore, visibility is identified as an influencing factor for the safe operation of tower cranes, and the tower crane hook is designated as the monitored component associated with this influencing factor. The monitored component associated with the influencing factor refers to the monitored component of the tower crane where the influencing factor causes a safety hazard among the various monitored components.

[0070] The specific method for determining the associated monitored parts is as follows: a pre-set impact factor association table can be retrieved to match the associated monitored parts corresponding to the impact factors. The impact factor association table includes multiple impact factors and their corresponding associated monitored parts.

[0071] It should be noted that the monitored part associated with the influence factor can be a single part, while in other embodiments, the monitored part associated with the influence factor can be multiple parts.

[0072] S103: Based on the influencing factor, display the real-time monitoring video corresponding to the associated monitored part in full screen so that the monitoring personnel can identify the safety hazards of the tower crane.

[0073] Specifically, after the influencing factors for the safe operation of tower cranes are determined, the corresponding influencing factor levels are matched according to a pre-set influencing factor level table. This table includes the influencing factors and their corresponding levels. A higher influencing factor level indicates a greater safety hazard, and the longer the real-time monitoring video of the monitored area associated with that influencing factor is displayed in full screen, the easier it is for personnel to identify potential safety hazards in the tower crane by viewing the video for an extended period.

[0074] After the impact factor level is determined, a preset display time matching table is retrieved to match the display time corresponding to the impact factor level. This display time matching table includes the shadow factor level and its corresponding display time. Finally, the real-time monitoring video of the associated monitored area is prioritized for display, then the system returns to normal, and the real-time monitoring video of each monitored area is displayed in a split-screen format.

[0075] In one feasible implementation, the monitored locations associated with an influencing factor can be multiple. The number of monitored locations associated with each influencing factor is counted; the higher the number, the more monitored locations affected by the factor, and thus the higher the influencing factor level. Based on the number of associated monitored locations, multiple monitored locations associated with the same influencing factor are prioritized for split-screen display (the display time is determined by the influencing factor level), and then the split-screen display of real-time monitoring videos of each monitored location of the tower crane is restored.

[0076] See Figure 2 This application discloses a flowchart of another method for remote monitoring of tower cranes, which can be implemented using a computer program or run on a tower crane remote monitoring device based on the von Neumann architecture. The computer program can be integrated into an application or run as a standalone utility application, specifically including:

[0077] S201: Acquire real-time monitoring videos of each monitored part of the tower crane when it is in operation, and display each real-time monitoring video on the monitoring screen in a split screen.

[0078] For details, please refer to step S101, which will not be repeated here.

[0079] S202: Obtain the slewing angle of the tower crane through a preset slewing sensor.

[0080] Specifically, the slewing sensor is a high-tech digital slewing monitoring device designed for the safety of tower cranes. It can collect the rotation angle of the tower crane. Tilting angle and GPS positioning functions can also be selected, allowing simultaneous collection of the tower crane's slewing and tilt angle (3D XYZ) and equipment positioning information. The slewing sensor can be the EP-HZ01 model; in other embodiments, the EP-HZ03 model can also be used. The slewing angle of the tower crane is obtained by the slewing sensor installed on the slewing gear ring of the tower crane.

[0081] S203: If the slewing angle is not greater than the angle threshold, then continue to obtain the next influencing factor for the safe operation of the tower crane.

[0082] S204: If the slewing angle is greater than the angle threshold, the slewing angle is determined to be an influencing factor for the safe operation of the tower crane, and the slewing table of the tower crane is determined to be the monitored part associated with the influencing factor.

[0083] Specifically, the slewing angle is the angle by which the tower crane rotates continuously to the left or right. The angle threshold is the maximum angle the tower crane can rotate. To prevent excessive slewing angles from causing the cables on the tower crane to twist and knot, resulting in cable damage, a slewing limiter is installed on the slewing gear ring of the tower crane to restrict its rotation, thus creating an angle threshold. Generally, the slewing angle should not exceed 1.5 revolutions to the left or right continuously, i.e., the slewing angle should not exceed 540 degrees, and the angle threshold is 540 degrees. In other embodiments, the angle threshold can also be set to 360 degrees.

[0084] If the slewing angle is not greater than the angle threshold, it indicates that the tower crane's slewing is normal and there is no safety hazard of cable damage. Then, the next influencing factor for the safe operation of the tower crane is obtained. It should be noted that in other embodiments, multiple slewing angles can be obtained within a preset time period, such as 10 minutes. If all multiple slewing angles are not greater than the angle threshold, it indicates that the tower crane's slewing is normal. If any of the multiple slewing angles exceeds the angle threshold, it indicates that the tower crane's slewing is abnormal.

[0085] If the slewing angle exceeds a threshold value, it indicates an abnormality in the tower crane's slewing. Therefore, the slewing angle is determined as an influencing factor for the safe operation of the tower crane. Further, based on a pre-set influencing factor association table, the associated monitored component is matched to the slewing angle (influence factor). This associated monitored component is the tower crane's slewing platform, i.e., the slewing mechanism, which includes the slewing gear ring. It should be noted that the tower crane's slewing platform functions as a working device to enable the jib to rotate left and right around the tower crane's centerline.

[0086] S205: Based on the influencing factor, the real-time monitoring video corresponding to the slewing table of the tower crane is displayed in full screen for the third preset time.

[0087] S206: After the third preset time, each real-time monitoring video will be displayed in a split screen.

[0088] Specifically, if the slewing angle is determined to be an influencing factor for the safe operation of the tower crane, after acquiring real-time monitoring videos of each monitored part, the server will prioritize and display the real-time monitoring videos captured by the cameras on the slewing platform of the tower crane on a separate display screen in the monitoring room. The display duration is a third preset time, which can be obtained through a preset time matching table. The preset time matching table includes the influencing factor and its corresponding preset time. The third preset time corresponding to the slewing angle (influence factor) can be obtained by matching the preset time matching table.

[0089] After the real-time monitoring video of the rotary table is first displayed on the monitoring screen for a third preset time, a pre-set decoder automatically splits the real-time monitoring video of each monitored location acquired by the server into multiple screens on the monitoring screen. The number of screens on the monitoring screen is equal to the number of real-time monitoring videos of each monitored location. This is existing technology and will not be elaborated further.

[0090] In one feasible implementation, the number of non-standard operations by the tower crane operator within a first preset time period is obtained.

[0091] The number of non-standard operations is compared with the threshold number. If the number of non-standard operations is less than the threshold number, the next influencing factor for the safe operation of the tower crane is obtained.

[0092] If the number of non-standard operations is not less than the threshold number, then non-standard operations are determined to be an influencing factor on the safe operation of the tower crane, and the operator's cab of the tower crane is determined to be the monitored part associated with the influencing factor.

[0093] Based on the influencing factor, the real-time monitoring video corresponding to the operator's cab of the tower crane is displayed in full screen for the second preset time.

[0094] After the second preset time, the real-time monitoring videos are displayed in split screen.

[0095] Specifically, the first preset time is 10 minutes. In other embodiments, the first preset time can also be 15 minutes. The method for obtaining the number of non-standard operations by the tower crane operator within the first preset time is as follows: personnel can observe the monitoring video of the tower crane's cab, count the number of non-standard operations, and then the server receives the number of non-standard operations input by the personnel. The threshold number is the critical number of times the operator will perform non-standard operations. If the number of non-standard operations is less than the threshold number, it indicates that the number of non-standard operations by the operator is small and will not lead to safety hazards. Therefore, it is not necessary to identify non-standard operations as an influencing factor and continue to obtain the next influencing factor.

[0096] If the number of non-standard operations exceeds or equals the threshold, it indicates a high frequency of non-standard operations, which is highly likely to lead to safety hazards. Therefore, non-standard operations are identified as an influencing factor. Based on the influencing factor, the associated monitoring location (cab) and the priority full-screen display time (second preset time) are further determined. After the second preset time, the real-time monitoring video of the tower crane's cab is displayed in full screen for the second preset time, and then the real-time monitoring video of each monitored location is displayed in split screen.

[0097] In another feasible implementation, the visibility of the tower crane within a preset range is obtained using a visibility sensor;

[0098] If the visibility is greater than the visibility threshold, then continue to obtain the next influencing factor for the safe operation of the tower crane;

[0099] If the visibility is not greater than the visibility threshold, then visibility is determined as an influencing factor for the safe operation of the tower crane, and the hook of the tower crane is determined as the monitored part associated with the influencing factor.

[0100] Based on the influencing factors, the real-time monitoring video corresponding to the hook of the tower crane is displayed in full screen for the fourth preset time.

[0101] After the fourth preset time, the real-time monitoring videos are displayed in split screen.

[0102] Specifically, visibility within a preset range for the tower crane is obtained using a pre-set visibility sensor. This preset range can be the working distance range of the tower crane or a range greater than the working distance range. The visibility threshold is the minimum visibility that affects the operator's field of vision. If the obtained visibility is greater than or equal to the visibility threshold, it indicates that the environmental visibility will affect the operator's operation of the tower crane; therefore, visibility is determined as an influencing factor. Next, based on the influencing factor, the associated monitoring location (hook) and the priority full-screen display time (fourth preset time) are further determined. After the fourth preset time, the real-time monitoring video of the tower crane hook is displayed in full screen, and then the real-time monitoring video of each monitored location is displayed in split screen.

[0103] See Figure 3 This application discloses a flowchart of another method for remote monitoring of tower cranes, which can be implemented using a computer program or run on a tower crane remote monitoring device based on the von Neumann architecture. The computer program can be integrated into an application or run as a standalone utility application, specifically including:

[0104] S301: Acquire real-time monitoring videos of each monitored part of the tower crane when it is in operation, and display each real-time monitoring video on the monitoring screen in a split screen.

[0105] S302: Obtain the influencing factors of the safe operation of tower cranes and determine the monitored parts associated with the influencing factors.

[0106] For details, please refer to steps S101-S102, which will not be repeated here.

[0107] S303: Assess the risk level of the impact factors to obtain the impact factor level.

[0108] Specifically, after determining the influencing factors for the safe operation of tower cranes, a risk level assessment is performed on these factors using a pre-set influencing factor level table. This involves matching the influencing factor level table to obtain its level. The influencing factor level table has been discussed in detail in step S103 and will not be repeated here. For example, the table includes the following influencing factors: visibility (level 5); slewing angle (level 4); and tilt angle (level 6). The influencing factor levels range from 1 to 10. If the determined influencing factor is slewing angle, the risk level assessment yields a level 4. It should be noted that a higher influencing factor level indicates a greater safety hazard caused by that factor.

[0109] S304: Based on the impact factor level, determine the full-screen display time of the real-time monitoring video corresponding to the associated monitored part. The higher the impact factor level, the longer the full-screen display time.

[0110] For details, please refer to step S103, which will not be repeated here.

[0111] S305: Determine whether there are multiple impact factor levels. If there are multiple impact factor levels, determine the order in which the real-time monitoring videos are displayed in full screen according to each impact factor level. The higher the impact factor level, the earlier the real-time monitoring videos are displayed in full screen.

[0112] S306: After the real-time monitoring video corresponding to the associated monitored part is displayed in full screen, each real-time monitoring video is displayed in split screen so that the monitoring personnel can identify the safety hazards of the tower crane.

[0113] Specifically, if there are multiple factors influencing the safe operation of a tower crane, meaning there are multiple levels of these factors, then the real-time monitoring videos of the monitored parts associated with each of these factors need to be displayed in full screen individually. Next, the factors are sorted from highest to lowest level, and the monitored parts associated with each factor are displayed in full screen sequentially according to this order. Finally, after displaying each part in full screen in order of its display time, the monitored parts of the tower crane are processed into a split-screen display using a pre-set decoder and displayed on a monitoring screen, facilitating monitoring of the overall operating status of the tower crane.

[0114] In one feasible implementation, step S302 further includes: counting the frequency of occurrence of influencing factors within a preset time period before the current moment.

[0115] Based on the frequency of occurrence, the position of the real-time monitoring video corresponding to the monitored part associated with the influencing factor in the split-screen display is adjusted so that monitoring personnel can identify safety hazards of tower cranes. The higher the frequency of occurrence, the closer the position in the split-screen display is to the central area.

[0116] Specifically, after determining the influencing factors for the safe operation of tower cranes, the historical records of these factors within a preset time period prior to the current moment are retrieved. The frequency of each influencing factor within that preset time period is calculated. A higher frequency indicates a greater probability of safety hazards in the monitored area associated with that factor, requiring closer monitoring. The influencing factors are then sorted from highest to lowest frequency. Finally, after splitting the screen using a preset decoder, the real-time monitoring video of the monitored area associated with the highest-ranked (most frequent) influencing factor is adjusted to the center of the screen (closest to the center of the monitoring display in the split-screen display).

[0117] The implementation principle of the remote monitoring method for tower cranes in this application embodiment is as follows: Real-time monitoring videos of each monitored part of the tower crane are acquired when it is in operation. Then, the influencing factors for the safe operation of the tower crane are determined. The monitored parts associated with the influencing factors are matched using an influencing factor association table. The real-time monitoring videos of the associated monitored parts are retrieved and displayed full-screen on the monitoring display screen. The full-screen display time is determined according to the magnitude of the influencing factor's influence level. After the full-screen display, the split-screen display of the real-time monitoring videos of each monitored part of the tower crane is restored.
