[0032] Figure 1 A flow chart of a tower crane layout method in a construction site provided in Embodiment 1 of the present invention. This embodiment can be applied to the situation of automatically determining the tower crane layout in a construction site. The method can be executed by a tower crane layout device in a construction site. The tower crane layout device in the construction site can be implemented in the form of hardware and / or software and specifically configured in an electronic device, such as a server.

[0033] See also Figure 1 The tower crane layout method in the construction site shown includes:

[0034] S101. Obtain spatial information of a construction site, spatial information of at least one building to be constructed in the construction site, meteorological information at the construction site during at least one construction period, spatial information of a tower crane, and material parameter information of the tower crane, as well as obtain at least one candidate tower crane position in the construction site and ground parameter information at each candidate tower crane position.

[0035] In this embodiment, the spatial information of the construction site may refer to the three-dimensional spatial information of the construction site, which may include but is not limited to the real location of the construction site, the length of the construction site, the width of the construction site, and the ground height distribution in the construction site. The building to be built may be a building to be built in the construction site; the spatial information of the building to be built is the three-dimensional spatial information of the building to be built, which may include the construction location, height and length of the building to be built. The spatial information of the tower crane may be the three-dimensional spatial information obtained by the candidate tower crane, which may include but is not limited to the minimum length of the crane arm, the maximum length of the crane arm, the minimum height of the tower crane and the maximum height of the tower crane; the construction time period may be the time period in the construction site when the tower crane is required for construction; the meteorological information may include but is not limited to temperature, humidity and wind speed. The material parameter information may be the parameter information of the constituent materials of the tower crane; for example, if the mechanical arm of the tower crane is a steel mechanical arm, the material parameter information may include the physical parameters of the steel. The ground parameter information may include but is not limited to the dry density, water content, cohesion, effective stress and gravity of the ground soil.

[0036] S102. For each candidate tower crane position, based on the meteorological information in each construction time period, the ground parameter information at the candidate tower crane position, the spatial information of the tower crane and the material parameter information of the tower crane, respectively predict the sway distance of the tower crane boom at the candidate tower crane position in each construction time period.

[0037] In this embodiment, the sway distance of the tower crane arm can be the maximum distance that the tower crane arm can reach when swaying. Specifically, a certain algorithm is used to predict the sway distance of the tower crane arm at the candidate tower crane position in each construction time period according to the meteorological information in each construction time period, the ground parameter information at the candidate tower crane position, the spatial information of the tower crane, and the material parameter information of the tower crane for each candidate tower crane position.

[0038] In this embodiment, the tower crane installation position may be a position where the tower crane is installed in a construction site. Specifically, a certain algorithm may be used to determine at least one tower crane installation position in the construction site according to the construction site spatial information, the tower crane spatial information, and the spatial information of each building to be built.

[0039] S103. For each construction time period, based on the spatial information of the tower crane, the positions of each candidate tower crane, the spatial information of each building to be built and the swaying distance of the tower crane boom at each candidate tower crane position within the construction time period, verify whether the tower crane at each candidate tower crane position can safely build the building to be built within the construction time period, and obtain the target verification result of each candidate tower crane position within the construction time period.

[0040] Specifically, a certain algorithm is adopted to verify, for each construction time period, whether the tower crane at each candidate tower crane position can safely build the building to be constructed within the construction time period based on the spatial information of the tower crane, the positions of each candidate tower crane, the spatial information of each building to be constructed and the swaying distance of the tower crane boom at each candidate tower crane position within the construction time period, so as to obtain the target verification result of each candidate tower crane position within the construction time period.

[0041] S104. Allocate tower cranes to candidate tower crane positions whose target verification results in each construction time period are all verified.

[0042] Optionally, for each tower crane installation position to be assigned, a reference building is determined based on the tower crane installation position, the tower crane spatial information and the spatial information of each building to be built; the spatial information and meteorological information of the reference building are input into a trained fatigue detection model to obtain the predicted tower crane fatigue type within the construction time period; based on the predicted tower crane fatigue type and the fatigue type of each candidate tower crane, a target tower crane at the tower crane installation position is determined from each candidate tower crane.

[0043] In this embodiment, the reference building is a building to be built by the tower crane at the tower crane installation location; the fatigue detection model can be used to predict the fatigue type of the tower crane; wherein the fatigue detection model can be a deep learning model. Predicting the fatigue type of the tower crane is to predict the type of fatigue that may occur in the tower crane at the tower crane installation location during the construction period. The target tower crane can be a candidate tower crane to be installed at the final tower crane installation location.

[0044] Specifically, for each tower crane installation position, the tower crane operation area at the tower crane installation position can be determined according to the tower crane installation position and the tower crane spatial information; for each building to be built, the building coverage area of ​​the building to be built can be determined according to the spatial information of the building to be built; the building to be built whose building coverage area is within the tower crane operation area at the tower crane installation position is determined as the reference building; the spatial information of each reference building and the meteorological information during the construction time period are input into the trained fatigue detection model to obtain the predicted tower crane fatigue type during the construction time period; according to the fatigue type of each candidate tower crane, a reference tower crane with a fatigue type different from the predicted tower crane fatigue type is screened out from the candidate tower cranes; and the target tower crane at the tower crane installation position is determined from the reference tower cranes.

[0045] In an optional embodiment, the fatigue detection model can be trained by using spatial information of historical buildings in historical construction operations, meteorological information during the construction period of historical construction operations, and actual fatigue types of tower cranes in historical construction operations.

[0046] It can be understood that by adopting the above-mentioned technical scheme, it is possible to determine the predicted fatigue type at the tower crane installation location during the construction period through meteorological information, tower crane spatial information and spatial information of the building to be built, thereby allocating candidate tower cranes to each tower crane installation location according to the fatigue type of each candidate tower crane and the predicted fatigue type at the tower crane installation location. When realizing the automatic allocation of tower cranes, it is possible to avoid the predicted fatigue type at the tower crane installation location affecting the safe operation of the target tower crane, thereby ensuring that the target tower crane installed at the tower crane installation location can operate safely during the construction period, thereby improving the safety of construction operations in the construction site.

[0047] In an optional embodiment, after allocating a target crane to each crane installation position, it also includes: generating a crane identifier for each target crane; sending the spatial information of the construction site, the spatial information of each building to be built, each crane installation position and the crane identifier of the target crane corresponding to each crane installation position to a browser compatible with WebGL; the browser initializes the three-dimensional scene, and initializes the size of the canvas node by detecting the window ratio of the browser; sets rendering, and implements an animation loop through the requestAnimation method; creates a perspectiveCamera perspective camera, adds an OrbitControls controller to the created perspective camera, and adds it to the three-dimensional scene. A three-dimensional site model of a construction site including the buildings to be built is created through the spatial information of the construction site and the spatial information of each building to be built, and the texture of the three-dimensional site model is set; according to the crane identifier of the target crane, the corresponding target crane model is loaded; through EventEmitter, the addEventListener event listening method and the dispatch event throwing method are created; addEventListener listens to user click events and subscribes to user click events at the same time, and publishes this event when the model is loaded; the dispatch method is used for event driving between different three-dimensional model processing modules, and each module only contains the code of the module function, which does not conflict with each other and is used for decoupling purposes. During the internal construction operation of the construction site, the browser side will obtain real-time meteorological data and the operating parameters of the target crane, such as the rotation angle and the tilt angle, etc. According to the real-time meteorological data, the model size and operating parameters of the three-dimensional model of each target crane, and the trained logistic regression model, the real-time dangerous state of each target crane is predicted; and the real-time dangerous state and real-time meteorological data are displayed in the browser interface.

[0048] The embodiment of the present invention obtains spatial information of a construction site, spatial information of at least one building to be built in the construction site, meteorological information at the construction site in at least one construction time period, spatial information of a tower crane and material parameter information of the tower crane, and obtains at least one candidate tower crane position in the construction site, and ground parameter information at each candidate tower crane position; for each candidate tower crane position, the tower crane boom sway distance is predicted at the candidate tower crane position in each construction time period according to the meteorological information in each construction time period, the ground parameter information at the candidate tower crane position, the tower crane spatial information and the tower crane material parameter information; for each construction time period, the tower crane spatial information, the tower crane spatial information and the tower crane material parameter information are respectively predicted. The spatial information of each building to be constructed and the swaying distance of the tower crane boom at each candidate tower crane position within the construction time period are used to verify whether the tower crane at each candidate tower crane position can safely construct the building to be constructed within the construction time period, and obtain the target verification result of each candidate tower crane position within the construction time period; tower cranes are allocated to the candidate tower crane positions whose target verification results within each construction time period are all verified, and the swaying distance of the tower crane within the construction time period can be automatically predicted according to the spatial information of the building to be constructed, the spatial information of the tower crane, the meteorological information and the material parameter information of the tower crane, and whether the tower crane position is safe based on the swaying distance, thereby improving the efficiency of the tower crane layout in the construction site and improving the safety of the tower crane layout.

[0091] It should be noted that, for the parts not described in detail in the embodiments of the present invention, reference may be made to the descriptions in the aforementioned embodiments.

[0092] See also Figure 3 The tower crane layout method in the construction site shown includes:

[0093] S301. Obtain spatial information of a construction site, spatial information of at least one building to be built in the construction site, meteorological information at the construction site during at least one construction time period, spatial information of a tower crane, and material parameter information of the tower crane, as well as obtain at least one candidate tower crane position in the construction site and ground parameter information at each candidate tower crane position.

[0094] S302. For each candidate tower crane position, based on the meteorological information in each construction time period, the ground parameter information at the candidate tower crane position, the spatial information of the tower crane and the material parameter information of the tower crane, respectively predict the sway distance of the tower crane boom at the candidate tower crane position in each construction time period.

[0095] S303. For each construction time period, for each candidate tower crane position within the construction time period, based on the candidate tower crane position and the tower crane boom swaying distance at the candidate tower crane position, as well as other tower crane positions and the tower crane boom swaying distances at other tower crane positions, verify whether there is a collision risk between the tower crane at the candidate tower crane position and the tower cranes at other tower crane positions, and obtain a first verification result; wherein the other tower crane positions are candidate tower crane positions other than the candidate tower crane position.

[0096] In this embodiment, the first verification result can be used to characterize whether there is a collision risk between the tower crane at the candidate tower crane position and the tower cranes at other tower crane positions. If the first verification result is a passed verification, it means that there is no collision risk between the tower crane at the candidate tower crane position and the tower cranes at other tower crane positions; if the first verification result is a failed verification, it means that there is a collision risk between the tower crane at the candidate tower crane position and the tower cranes at other tower crane positions.

[0097] Specifically, a certain algorithm is adopted to verify whether there is a collision risk between the tower crane at the candidate tower crane position and the tower crane at other tower crane positions based on the candidate tower crane position and the tower crane arm swaying distance at the candidate tower crane position, as well as the tower crane arm swaying distances at other tower crane positions and other tower crane positions, to obtain a first verification result.

[0098] Optionally, based on the candidate tower crane position and the tower crane boom sway distance at the candidate tower crane position, as well as the tower crane boom sway distances at other tower crane positions and other tower crane positions, it is verified whether there is a collision risk between the tower crane at the candidate tower crane position and the tower cranes at other tower crane positions to obtain a first verification result, including: for each other tower crane position, determining the tower crane distance between the candidate tower crane position and the other tower crane positions; determining the boom distance between the candidate tower crane position and the other tower crane positions based on the tower crane boom sway distance at the candidate tower crane position and the tower crane boom sway distance at other tower crane positions; verifying whether the candidate tower crane at the candidate tower crane position can operate safely based on the boom distance and the crane distance to obtain a first verification result.

[0099] The distance between the booms can be the minimum distance between the booms of two tower cranes. Specifically, for each other tower crane position, determine the shortest line segment connecting the candidate tower crane position and the other tower crane position, and determine the distance of the shortest line segment as the distance between the tower cranes; based on the boom swing distance of the tower crane at the candidate tower crane position, determine the farthest end position of the boom of the tower crane at the candidate position in the direction of the shortest line segment; and based on the boom swing distance of the tower crane at the other tower crane position, determine the farthest end position of the boom of the tower crane at the other position in the direction of the shortest line segment; based on the farthest end position of the boom of the tower crane at the candidate position and the farthest end position of the boom of the tower crane at the other position end positions, determine the distance between the crane arms; if the distance between the crane arms is a negative number, for example, in the direction of the shortest line segment, the farthest end position of the crane arm of the tower crane on one side is between the farthest end position of the crane arm of the tower crane on the other side and the position of the tower crane on the other side, then determine that the first verification result is failed; if the distance between the crane arms is not a negative number, multiply the preset safety factor by the distance between the cranes to obtain the minimum safety distance; compare the minimum safety distance and the distance between the crane arms; if the minimum safety distance is greater than the distance between the crane arms, then the first verification result is that the verification is passed; otherwise, the first verification result is that the verification is failed.

[0100] It can be understood that by adopting the above technical scheme, for each other tower crane position, the tower crane distance between the candidate tower crane position and other tower crane positions is determined; based on the tower crane arm sway distance of the candidate tower crane position and the tower crane arm sway distance of other tower crane positions, the boom distance between the candidate tower crane position and other tower crane positions is determined; based on the boom distance and the tower crane distance, it is verified whether the candidate tower crane at the candidate tower crane position can operate safely, to obtain a first verification result, thereby improving the accuracy of the first verification result.

[0101] Optionally, based on the candidate tower crane position, the spatial information of the tower crane and the spatial information of each building to be built, it is verified whether the tower crane at the candidate tower crane position can complete the operation on the building to be built during the construction time period to obtain a second verification result, including: for each building to be built, based on the candidate tower crane position and the spatial information of the building to be built, determining the maximum distance between the candidate tower crane position and the boundary of the building to be built; comparing the maximum length of the crane arm with the maximum distance to the building to be built to obtain a comparison result; verifying whether there is a comparison result in which the maximum length of the crane arm is greater than or equal to the maximum distance to the building to be built to obtain a second verification result.

[0102] S304. Verify, based on the candidate crane positions, the crane's spatial information and the spatial information of each building to be constructed, whether the crane at the candidate crane position can perform complete operations on the building to be constructed during the construction period, and obtain a second verification result.

[0103] In this embodiment, the second verification result can indicate whether the tower crane at the candidate tower crane position can perform complete operations on the building to be constructed during the construction period. If the second verification result is a verification pass, it indicates that the tower crane at the candidate tower crane position can perform complete operations on the building to be constructed during the construction period. If the second verification result is a verification fail, it indicates that the tower crane at the candidate tower crane position cannot perform complete operations on the building to be constructed during the construction period.

[0104] Specifically, a certain algorithm is adopted to verify whether the tower crane at the candidate tower crane position can complete the operation on the building to be constructed within the construction period according to the candidate tower crane position, the spatial information of the tower crane and the spatial information of each building to be constructed, so as to obtain a second verification result.

[0105] Optionally, the spatial information of the tower crane includes the maximum length of the boom; for each building to be built, based on the candidate tower crane position, the spatial information of the tower crane and the spatial information of each building to be built, verify whether the tower crane at the candidate tower crane position can complete the operation on the building to be built within the construction time period, and obtain a second verification result, including: for each building to be built, based on the candidate tower crane position and the spatial information of the building to be built, determine the farthest distance between the candidate tower crane position and the boundary of the building to be built; compare the maximum length of the boom with the farthest distance to the building to be built to obtain a comparison result; verify whether there is a comparison result in which the maximum length of the boom is greater than or equal to the farthest distance to the building to be built, and obtain a second verification result.

[0106] Specifically, for each building to be built, the boundary of the building to be built is determined according to the spatial information of the building to be built; the farthest distance between the candidate tower crane position and the boundary of the building to be built is determined; the maximum length of the crane arm and the farthest distance corresponding to the building to be built are compared to obtain a comparison result between the candidate tower crane position and the farthest distance of the building to be built; it is checked whether there is a comparison result in which the maximum length of the crane arm is greater than or equal to the farthest distance of the building to be built among the comparison results between the candidate tower crane position and the farthest distances of each building to be built; if so, the second verification result is determined to be a passed verification; otherwise, the second verification result is determined to be a failed verification.

[0107] In an optional embodiment, the spatial information of the building to be built may include the location of the building to be built, the width of the building to be built and the length of the building to be built; the boundary shape of the building to be built may be determined based on the width of the building to be built and the length of the building to be built; and a boundary with the location of the building to be built as the center and the shape of the boundary may be determined as the boundary of the building to be built.

[0108] It can be understood that by adopting the above-mentioned technical scheme, by comparing whether the maximum length of the crane arm is with the farthest distance of each building to be built, it can be determined whether there is a complete building to be built within the maximum operating range of the candidate tower crane, thereby determining whether the candidate tower crane at the candidate tower crane position can complete the operation of the building to be built, thereby improving the accuracy of the second verification result.

[0109] S305. Determine a target verification result for the candidate tower crane position according to the first verification result and the second verification result.

[0110] Specifically, if both the first verification result and the second verification result are verification passed, then it is determined that the target verification result of the candidate tower crane position is verification passed; otherwise, the target verification result of the candidate tower crane position is verification failed.

[0111] S306. Allocate tower cranes to the candidate tower crane positions whose target verification results in each construction time period are all verified.

[0112] Optionally, the spatial information of the construction site includes the length and width of the construction site; the candidate tower crane positions are determined in the following manner, including: calculating the rectangular area of ​​the construction site based on the length and width of the construction site; calculating the coverage area of ​​a single candidate tower crane based on the spatial information of the tower crane; determining the maximum number of tower cranes on the construction site based on the rectangular area and the coverage area; determining the candidate tower crane positions in the construction site based on the maximum number of tower cranes; the number of candidate tower crane positions is the same as the maximum number of tower cranes.

[0113] The coverage area may be the ground area covered by the boom of the candidate tower crane. Specifically, the product of the length of the construction site and the width of the construction site is determined as the rectangular area of ​​the construction site; the coverage area of ​​a single candidate tower crane is calculated based on the spatial information of the tower crane; the ratio of the rectangular area to the coverage area is determined, and the obtained ratio is rounded up, that is, the smallest integer greater than or equal to the ratio is determined to obtain the maximum number of tower cranes on the construction site; and the candidate tower crane positions with the same number as the maximum number of tower cranes are generated in the construction site. Exemplarily, the maximum number of tower cranes can be determined by the following formula and the maximum length of the boom:

[0114] ;

[0115] Among them, N represents the maximum number of tower cranes; L represents the length of the construction site; W represents the width of the construction site; and R represents the maximum length of the crane arm.

[0116] It can be understood that by adopting the above-mentioned technical scheme, the maximum number of tower cranes on the construction site can be determined according to the rectangular area of ​​the construction site and the coverage area of ​​the candidate tower cranes, which can avoid the existence of too many tower cranes in the construction site and the duplication of operating areas between multiple tower cranes, resulting in waste of tower crane resources. It can also limit the distance between each tower crane and improve the safety of construction operations on the construction site.

[0117] The embodiment of the present invention verifies, for each candidate tower crane position, whether there is a risk of collision between the tower crane at the candidate tower crane position and the tower crane boom swing distance at the candidate tower crane position, as well as the tower crane boom swing distances at other tower crane positions and other tower crane positions, to obtain a first verification result; wherein the other tower crane positions are candidate tower crane positions other than the candidate tower crane position; based on the candidate tower crane position, the spatial information of the tower crane and the spatial information of each building to be constructed, it is verified whether the tower crane at the candidate tower crane position can complete the operation on the building to be constructed within the construction time period, to obtain a second verification result; based on the first verification result and the second verification result, a target verification result for the candidate tower crane position is determined, thereby improving the accuracy of the target verification result, thereby ensuring that candidate tower crane positions that can complete the construction of the building and operate safely are screened out.
