[0002] As an important engineering facility, cranes can move and transport large materials vertically and horizontally through actions such as lifting, luffing, and slewing. They can be widely used in construction sites and other scenarios. Traditional cranes require an operator in the control room to operate them, which depends on the operator's skills and experience and has a low level of intelligence.
[0003] To improve the intelligence level of hoisting equipment, existing tracking and monitoring of intelligent cranes relies on cameras and sensors installed on the crane boom and other locations to track and monitor the operation process, status parameters, and environmental parameters.

[0076] Lifting decisions are planned based on the second eigenvalue and the digital twin model.
[0077] In detail, the present invention provides a modeling method for lifting operations to address the shortcomings of existing lifting operation monitoring systems that cannot meet operational needs and pose safety hazards. By collecting data from multiple dimensions through a data acquisition terminal 30 and a drone 20, the method achieves full coverage of the operational area 40, avoiding blind spots in monitoring. Furthermore, it formulates lifting strategies based on the monitored data to meet the lifting operation needs in different scenarios.
[0078] In some possible embodiments of the present invention, the step of obtaining the first feature value of the corresponding target object specifically includes:
[0079] Obtain the first feature parameter and the second feature parameter of the corresponding target object, wherein the first feature parameter is the image parameter acquired by the UAV 20, and the second feature parameter is the depth parameter acquired by the UAV 20;
[0080] The first feature value is generated based on the first feature parameter and the second feature parameter.
[0081] Specifically, this embodiment provides an implementation method for obtaining the first feature value of the corresponding target object. The first feature value is generated based on the first feature parameters and the second feature parameters collected by the UAV 20, which provides a basis for the construction of a virtual model of the lifting equipment and the surrounding working environment.
[0082] It should be noted that the first feature parameter collected by the UAV 20 includes the image parameters of the lifting equipment and the target object, and the second feature parameter includes the depth parameters of the lifting equipment and the target object.
[0083] In some possible embodiments of the present invention, the step of obtaining the second feature value of the corresponding target object specifically includes:
[0084] The third and fourth feature parameters of the corresponding target object are obtained. The third feature parameter is the image parameter acquired by the acquisition terminal 30, and the fourth feature parameter is the depth parameter acquired by the acquisition terminal 30. The acquisition direction of the acquisition terminal 30 and the acquisition direction of the UAV 20 form an acquisition angle.
[0085] The second feature value is generated based on the third and fourth feature parameters.
[0086] Specifically, this embodiment provides an implementation method for obtaining the second feature value of the corresponding target object. The second feature value is generated based on the third and fourth feature parameters collected by the acquisition terminal 30, which provides a basis for the construction of a virtual model of the lifting equipment and the surrounding working environment.
[0087] It should be noted that the third feature parameter collected by the acquisition terminal 30 includes the image parameters of the lifting equipment and the target object, and the fourth feature parameter includes the depth parameters of the lifting equipment and the target object.
[0088] In some possible embodiments of the present invention, the step of constructing a digital twin model based on a first feature value specifically includes:
[0089] The first feature vector and the second feature vector collected by the UAV 20 are obtained. The first feature vector points to the regional features of the lifting equipment, and the second feature vector points to the regional features of the target object.
[0090] A first lifting equipment model is generated based on the first feature vector, and a prefabricated lifting equipment model is obtained based on the first lifting equipment model.
[0091] The first lifting equipment model is coupled with the prefabricated lifting equipment model to generate the second lifting equipment model;
[0092] Generate a regional environment model based on the second feature vector;
[0093] A digital twin model was constructed based on the second lifting equipment model and the regional environment model.
[0094] Specifically, this embodiment provides an implementation method for constructing a digital twin model based on a first feature value. By generating a first lifting equipment model based on the first feature value collected by the UAV 20 and coupling it with a prefabricated lifting equipment model, the accuracy of the digital twin model is improved.
[0095] In a possible implementation, the first crane model generated by collecting the first feature value through the drone 20 has poor accuracy and is difficult to meet the simulation requirements of the digital twin model. The pre-built crane model is a model of the actual crane constructed at a proportional scale in the digital twin space. Digital twin refers to the establishment of a model corresponding to reality in a digital space scene. The positional relationship, connection relationship, motion relationship and shape parameters of the actual physical parts can be accurately displayed through the digital twin model.
[0096] In some possible embodiments of the present invention, the steps of generating a first lifting equipment model based on a first feature vector and obtaining a prefabricated lifting equipment model based on the first lifting equipment model specifically include:
[0097] Obtain the coordinate parameters, contour parameters, and model parameters of the lifting equipment;
[0098] Generate the first crane model based on coordinate parameters, contour parameters, and model parameters;
[0099] The corresponding prefabricated lifting equipment model is determined based on the coordinate parameters, contour parameters, and model parameters.
[0100] Specifically, this embodiment provides an implementation method for obtaining a prefabricated lifting equipment model based on a first lifting equipment model. By obtaining the coordinate parameters, contour parameters, and model parameters of the lifting equipment, it is convenient to establish the first lifting equipment model and determine the prefabricated lifting equipment model, thus providing support for improving the accuracy of the first lifting equipment model through the prefabricated lifting equipment model.
[0101] In some possible embodiments of the present invention, the step of generating a regional environment model based on the second feature vector specifically includes:
[0102] Acquire the first region morphological parameters and the second region morphological parameters collected by the UAV 20, wherein the first region morphological parameters correspond to the hoisting start position parameters of the target object, and the second region morphological parameters correspond to the hoisting end position parameters of the target object;
[0103] Acquire hoisting environment parameters, and generate a regional environment model based on the hoisting environment parameters, the first region morphology parameters, and the second region morphology parameters. The hoisting environment parameters include at least the wind speed, wind level, wind pressure, and obstacles within the work area 40.
[0104] Specifically, this embodiment provides an implementation method for generating a regional environment model based on a second feature vector. The starting and ending points of the target object within the work area 40 are determined by the hoisting start position parameters and hoisting end position parameters. The regional environment model is generated in conjunction with the hoisting environment parameters, thereby improving the safety and accuracy of the hoisting operation.
[0105] In a possible implementation, the first region morphological parameter and the second region morphological parameter are position parameters that are manually input.
[0106] In a possible implementation, the first region morphological parameter and the second region morphological parameter are pre-marked working area 40 parameters.
[0107] In a possible implementation, the morphological parameters of the first and second regions are input into the digital twin model by marking the corresponding coordinates, thereby realizing the planning of the corresponding hoisting decisions.
[0108] In a possible implementation, by loading hoisting environment parameters, including wind speed, wind level, and wind pressure within the work area 40, into the area environment model, the area environment model can more realistically simulate the environment of the work area 40.
[0109] In a possible implementation, the hoisting environment parameters can be obtained by loading the average value within a continuous data collection time point to ensure the accuracy of the environmental simulation.
[0110] In a possible implementation, the acquisition of hoisting environment parameters can be updated in real time based on the collected data to ensure the immediacy of the environmental simulation.
[0111] In a possible implementation, the acquisition of hoisting environment parameters can be achieved by setting corresponding parameters, i.e., simulating a regional environment model under specific conditions, such as extreme environments like strong winds, heavy rain, and snow. This simulation of specific environments is beneficial for providing data support for planning hoisting strategies under extreme conditions.
[0112] In some possible embodiments of the present invention, the step of planning hoisting decisions based on the second feature value and the digital twin model specifically includes:
[0113] The third feature vector and the fourth feature vector collected by the acquisition terminal 30 are obtained. The third feature vector points to the action features of the lifting equipment, and the fourth feature vector points to the regional features of the target object.
[0114] The digital twin model is driven in real time based on the third and fourth feature vectors to display the actions of the lifting equipment in the corresponding actual environment in real time in the digital twin space.
[0115] Specifically, this embodiment provides an implementation method for planning hoisting decisions based on a second feature value and a digital twin model. By using the second feature value collected by the acquisition terminal 30 to drive the digital twin model in real time, hoisting decision planning is realized.
[0116] In a possible implementation, real-time driving means that the model's movements in the digital twin space are consistent with the crane's movements in the actual scene, and the motion relationships, positional relationships, and connection relationships between the crane model components in the digital twin space are adjusted in real time based on the detected data.
[0117] In a possible implementation, if the boom is detected to rotate 10° in the actual scene by the sensor, the corresponding boom rotation of 10° will also be detected in the corresponding digital twin space. If the crane is detected to rotate 5°, the corresponding crane model in the twin space will also rotate 5°. If the crane is detected to travel 10m, the corresponding crane model in the digital twin space will travel 10m. If the hook is detected to rise 15m, the corresponding hook in the twin space will also rise 15m.
[0118] In a possible implementation, the data acquisition terminal 30 includes an angle sensor, a temperature sensor, and a wind speed sensor, etc., to realize the acquisition angle, acquisition position, adjustment of the acquisition angle, and measurement of wind speed.
[0119] In a possible implementation, the digital twin model uses spatial markers in the planning of lifting strategies. These spatial markers are divided into work coordination points and path smoothing points. Work coordination points are locations where the crane needs to wait for coordination instructions after the hook's automated operation arrives. Path smoothing points are path intervention points where obstacles are considered to need to be avoided during work planning. The work planning simulation currently only considers the coordinated movement of the crane, boom, cable, and hook along the planned path.
[0120] In some possible embodiments of the present invention, after the step of driving the digital twin model in real time based on the third feature vector and the fourth feature vector to display the actions of the lifting equipment in the corresponding actual environment in real time in the digital twin space, the invention further includes:

[0125] Generate a mimicry hoisting trajectory for the target object based on the morphological parameters of the first and second regions.
[0126] Generate environmental digital modes based on hoisting environment parameters;
[0127] Based on the preset hoisting points, the mimicry hoisting trajectory, and the digital modality of the environment, a mimicry hoisting decision is generated for the corresponding target object, and the mimicry hoisting decision is executed.
[0128] Once the mimicry hoisting decision is completed and the hoisting of the target object meets the preset hoisting conditions, the hoisting decision is sent to the hoisting equipment.
[0129] Specifically, this embodiment provides an implementation method after planning the hoisting decision based on the second feature value and the digital twin model. By executing the mimicry hoisting decision, the hoisting decision is simulated before execution, ensuring the safety of the hoisting. Problems can also be discovered and resolved in a timely manner during the simulation, improving hoisting efficiency and reducing the existence of hoisting errors and the occurrence of accidents.
[0130] In some possible embodiments of the present invention, after the step of planning the hoisting decision based on the second feature value and the digital twin model, the specific steps include:
[0131] Within a continuous time acquisition node, the motion trajectory characteristics of the target object are obtained;
[0132] The instantaneous hoisting trajectory of the target object is generated based on the motion trajectory characteristics, and a judgment is made based on the instantaneous hoisting trajectory and the simulated hoisting trajectory.
[0133] An alarm is issued if the deviation rate between the real-time hoisting trajectory and the simulated hoisting trajectory is greater than the deviation threshold.
[0134] Specifically, this embodiment provides another implementation method after planning the hoisting decision based on the second feature value and the digital twin model. By acquiring the motion trajectory characteristics of the target object, the real-time hoisting trajectory of the target object is generated, thereby realizing the monitoring of the hoisting decision of the target object and improving the safety of the hoisting operation.
[0135] In a possible implementation, multiple instantaneous nodes of the motion trajectory features of the target object are extracted, and an instantaneous hoisting trajectory of the target object is generated based on the multiple instantaneous nodes.
[0136] In some specific embodiments of the present invention, such as Figures 1 to 3 As shown, this solution provides a modeling system for lifting operations, which uses the above-mentioned modeling method for lifting operations.
[0137] In some specific embodiments of the present invention, this solution provides a remote operating system, which further includes a remote control platform 50. The remote control platform 50 is connected to the server 10, the lifting equipment, the drone 20 and the data acquisition terminal 30 respectively, so as to realize remote planning and hoisting decisions.
[0138] The server 10 contains the aforementioned modeling system for lifting operations.
[0139] Specifically, this embodiment provides an implementation of a remote control platform 50, which performs remote control operations by cooperating with the digital twin space of the server 10.
[0140] In a possible implementation, a display is also included, showing the digital twin space on server 10, graphics and scenes captured in real time by a camera.
[0141] In a possible implementation, the remote control platform 50 controls the crane by connecting to onboard motion controllers, such as a boom controller (which controls the movement of the boom) or a chassis controller (which controls the movement of the chassis).
[0142] In a possible implementation, the remote control platform 50 includes remote control software for crawler cranes and multi-channel video playback software, etc.
[0143] In a possible implementation, the data acquisition terminal 30 is a data acquisition device installed on the crane, such as a camera, radar, or various sensors.
[0144] In some possible embodiments of the present invention, it further includes: a cloud control platform 60, which is connected to multiple work areas 40 to realize the planning and collaborative operation of multiple hoisting decisions; wherein each work area 40 has a remote control platform 50, a server 10, hoisting equipment, a drone 20 and a data acquisition terminal 30.
[0145] Specifically, this embodiment provides an implementation method for a cloud control platform 60. By setting up the cloud control platform 60, the configuration management of permissions and rules for drivers, vehicles, and remote operation platforms can be realized, as well as the comprehensive scheduling and monitoring of many-to-many relationships.
[0146] In a possible implementation, the crane's movements in the actual scene can be controlled via a cloud control platform 60, or via a remote control platform 50.
[0147] In a possible implementation, the cloud control platform 60 has greater management authority than the remote control platform 50.
[0148] In a possible implementation, the cloud control platform 60 is equivalent to a platform with access control functions. For example, multiple drivers can drive vehicles through multiple remote control platforms 50. Different drivers have different permissions. For example, the driver with the highest driving permission can operate multiple vehicles, while the driver with a lower level can only operate one or a few vehicles. Taking a crane as an example, different types of cranes generally refer to cranes with different lifting capacities. The higher the level, the larger the crane can be operated, while the lower the level cannot.
[0149] In one application scenario, the modeling system for lifting operations is generally divided into two main parts: the vehicle-side (tracked crane) and the remote-side (command center). A digital twin system is used to construct a digital twin of the tracked crane and its operating environment. The tracked crane is pre-modeled and parameter-bound, while the operating environment is constructed using a UAV for on-site surveying and mapping. The digital twin content is presented using real-time 3D rendering.
