Description

Technical Field

[0001] The present invention belongs to the technical field of crane operation safety monitoring, and in particular, relates to an intelligent crane operation safety intelligent monitoring, analysis and early warning system based on intelligence. Background Art

[0002] In recent years, with the rapid development of the real estate industry, tower cranes, as the main body of construction machinery in construction projects, have been widely used because of their advantages such as sufficient lifting height, large working space and high work efficiency. At the same time, the safety issues of tower cranes have also received widespread attention. Since the height of tower cranes is constantly adjusted and increased with the construction height of houses, the difficulty of monitoring the operation safety of tower cranes is also increasing. Failure to monitor any safety issues will increase the incidence of safety accidents, thereby affecting the development of the entire construction project.

[0003] The existing technology for safety monitoring of tower cranes has the following disadvantages:

[0004] (1) In the prior art, the safety monitoring of tower cranes is mostly done manually. Due to the high height of tower cranes, manual monitoring inevitably involves the risk of working at high altitudes, which in turn increases the incidence of safety accidents. For monitoring personnel, not only are they faced with extremely high work difficulty, but they also place a great workload on their bodies. At the same time, due to blind spots in their line of sight, it is difficult for monitoring personnel to detect subtle safety issues of tower cranes, resulting in low monitoring efficiency and poor real-time performance.

[0005] (2) Most existing technologies only focus on safety monitoring of the load-bearing capacity of tower cranes, but lack safety monitoring of the base appearance, tower frame and boom of tower cranes, resulting in a one-sided monitoring dimension and an inability to provide a reliable basis for the safety assessment of tower crane operations. At the same time, existing technologies focus on safety monitoring of the external environment in the area where the tower cranes are located, mainly on wind speed, but lack safety monitoring of precipitation, and are therefore unable to effectively ensure the safety of tower crane operations.

[0056] The tower crane self-safety monitoring module is used to perform self-safety monitoring on the tower crane and evaluate the self-safety factor of the tower crane.

[0057] Reference Figure 3 As shown, the tower crane's own safety monitoring module includes a base safety monitoring unit, a tower safety monitoring unit, a boom safety monitoring unit and a tie rod safety monitoring unit;

[0058] Specifically, the base safety monitoring unit is used to perform safety monitoring on the base of the tower crane, and the specific process is as follows:

[0059] A1: The high-definition camera installed in the inspection drone is used to collect the three-dimensional appearance image of the tower crane, thereby obtaining the three-dimensional appearance image of the tower crane, and extracting the three-dimensional appearance image corresponding to the base of the tower crane from it;

[0060] A2: Compare the three-dimensional appearance image corresponding to the tower crane base with the three-dimensional appearance image of the standard base of the tower crane stored in the data cloud platform, and then extract the appearance defect areas corresponding to the tower crane base, and number them as 1, 2, ..., i, ..., k, and then extract the appearance defect type and appearance defect area of ​​each appearance defect area;

[0061] A3: Match the appearance defect type of each appearance defect area of ​​the tower crane base with the preset risk impact factor per unit area of ​​each appearance defect type, and obtain the risk impact factor per unit area of ​​the appearance defect type of each appearance defect area of ​​the tower crane base, and then calculate the appearance safety factor of the tower crane base based on it. The calculation formula is: δ represents the appearance safety factor of the tower crane base, D i and χ i ″ respectively represent the appearance defect area of ​​the tower crane base corresponding to the i-th appearance defect area and the risk impact factor per unit area of ​​the appearance defect type.

[0062] In a specific embodiment of the present invention, the above-mentioned types of appearance defects include peeling and cracks, etc. The purpose of conducting safety monitoring on the appearance of the base of the tower crane is to consider that the base is the load-bearing foundation of the tower crane, and the safety condition of the base will affect the overall operating stability of the tower crane.

[0063] Specifically, the tower safety monitoring unit is used to perform safety monitoring on the tower of the tower crane, and the specific process is as follows:

[0064] B1: Identify the location of each tower node from the three-dimensional appearance image of the tower crane, and number the identified tower nodes as 1, 2, ..., m, ..., v respectively;

[0065] B2: constructing a three-dimensional rectangular coordinate system for the tower according to a preset three-dimensional rectangular coordinate system construction method, and then obtaining the three-dimensional coordinates corresponding to the position of each tower node based on the constructed three-dimensional rectangular coordinate system;

[0066] B3: Compare the three-dimensional coordinates corresponding to the positions of each tower node with the initial three-dimensional coordinates corresponding to the positions of each tower node stored in the data cloud platform, and calculate the tower node safety factor of the tower crane. The calculation formula is: Where α is the tower node safety factor of the tower crane, x m0 ,y m0 and z m0 They are respectively represented as the initial three-dimensional coordinate values ​​of the mth tower node position of the tower crane on the x-axis, y-axis and z-axis, m ,y m and z m They are respectively represented as the three-dimensional coordinate values ​​on the x-axis, y-axis and z-axis corresponding to the position of the m-th tower node of the tower crane;

[0067] It should be noted that, in the above-mentioned calculation formula for the safety factor of the tower node of the tower crane, the smaller the difference between the three-dimensional coordinate values ​​on the x-axis, y-axis and z-axis corresponding to a certain tower node position of the tower crane and the initial three-dimensional coordinate values ​​on the x-axis, y-axis and z-axis corresponding to the tower node position, the greater the safety factor of the tower node of the tower crane, indicating that the tower node of the tower crane meets the safety standards more.

[0068] In a specific embodiment of the present invention, safety monitoring and analysis is performed on the tower nodes of the tower crane. The purpose is that the position changes of the tower nodes can reflect the structural stability of the tower crane. If the position offset of a tower node is too large, the overall structure of the tower crane will be at risk of loosening, thereby affecting the overall operational stability.

[0069] B4: extracting the angle between the tower and the base of the tower crane from the three-dimensional appearance image of the tower crane, and recording it as the tower placement angle of the tower crane;

[0070] B5: Compare the tower crane's tower placement angle with the tower crane's tower standard placement angle in the data cloud platform to calculate the tower crane's tower placement safety factor. The calculation formula is: Where β is the safety factor of the tower crane, θ″ is the angle of the tower crane, and θ 0 It is expressed as the standard placement angle of the tower of a tower crane;

[0071] It should be noted that, in the above-mentioned tower crane tower placement safety factor calculation formula, the smaller the difference between the tower crane tower placement angle and the tower crane tower standard placement angle, the greater the tower crane tower placement safety factor, indicating that the tower crane tower placement is more in line with safety standards.

[0072] In a specific embodiment of the present invention, a safety monitoring and analysis is performed on the tower placement of a tower crane. The purpose is to take into account that the tower placement can reflect the offset condition of the overall structure of the tower crane. If the difference between the tower placement angle of the tower crane and the standard tower placement angle of the tower crane is too large, the tower crane will be at risk of tilting and collapsing.

[0073] B6: The tower safety factor of the tower crane is calculated based on the tower node safety factor of the tower crane and the tower placement safety factor of the tower crane.

[0074] Specifically, the boom safety monitoring unit is used to perform safety monitoring on the boom of the tower crane, and the specific process is as follows:

[0075] C1: Take the ground where the tower crane is located as the reference horizontal plane, and then obtain the angle formed between the boom of the tower crane and the reference horizontal plane, and record it as the boom operating angle of the tower crane;

[0076] C2: Compare the boom operating angle of the tower crane with the maximum allowable operating angle of the tower crane boom in the data cloud platform to calculate the boom operating safety factor of the tower crane. The calculation formula is: Where λ is the safety factor of the tower crane’s boom operation, j 0 It represents the maximum allowable operating angle of the tower crane's boom, and j represents the operating angle of the tower crane's boom.

[0077] It should be noted that, in the above-mentioned calculation formula for the safety factor of the boom operation of the tower crane, the smaller the boom operation angle of the tower crane, the greater the boom operation safety factor of the tower crane, indicating that the boom operation of the tower crane is more in line with safety standards.

[0078] In a specific embodiment of the present invention, the operation of the boom of the tower crane is safety monitored and analyzed. The purpose is to take into account that the boom is the operating body of the tower crane, and its operating safety condition will affect the overall operating stability of the tower crane. If the operating angle of the boom of the tower crane is too large, the boom of the tower crane will be at risk of deviation and collapse, which will be detrimental to the progress of the overall operation.

[0079] Specifically, the tie rod safety monitoring unit is used to perform safety monitoring on the tie rod of the tower crane, and the specific process is as follows:

[0080] D1: Identify the position of each tie rod from the three-dimensional appearance image of the tower crane, and then number each tie rod of the tower crane as 1, ..., p, ..., u;

[0081] D2: Using a tension sensor to detect the tension borne by each tie rod of the tower crane, and then obtaining the tension borne by each tie rod of the tower crane;

[0082] D3: Compare the tension borne by each tie rod of the tower crane with the maximum tension that the tie rod of the tower crane can withstand stored in the data cloud platform, and calculate the load-bearing safety factor of the tie rod of the tower crane. The calculation formula is: in It is expressed as the safety factor of the tower crane’s tie rod load, F″ is expressed as the maximum tension that the tower crane’s tie rod can withstand, f p It is expressed as the tension borne by the pth tie rod of the tower crane;

[0083] It should be noted that, in the above-mentioned calculation formula for the safety factor of the tie rod load-bearing of the tower crane, the smaller the tension borne by a certain tie rod of the tower crane, the greater the safety factor of the tie rod load-bearing of the tower crane, indicating that the tie rod load-bearing of the tower crane is more in line with the safety standards.

[0084] D4: Based on the obtained tension on each tie rod of the tower crane, the maximum tension and minimum tension on the tie rod are extracted, and then the safety factor of the force distribution of the tie rod of the tower crane is calculated. The calculation formula is: Where η is the safety factor of the tower crane's tie rod force distribution, f max and f min They represent the maximum and minimum tensions that the rod can bear, respectively. 0 ' represents the maximum tension difference that the pull rod of the preset tower crane can withstand;

[0085] It should be noted that, in the above-mentioned calculation formula for the safety factor of the force distribution of the tie rod of the tower crane, the smaller the difference between the maximum tension and the minimum tension borne by the tie rod, the greater the safety factor of the force distribution of the tie rod of the tower crane, indicating that the force distribution of the tie rod of the tower crane is more in line with the safety standards.

[0086] In a specific embodiment of the present invention, a safety analysis is performed on the force distribution of the tie rod of the tower crane. The purpose is to take into account the negative impact of uneven force on the tower crane. If the difference between the maximum tension and the minimum tension borne by the tie rod is too large, the risk of tipping over of the tower crane will increase.

[0087] D5: Based on the safety factor of the tower crane's tie rod load and the safety factor of the tower crane's tie rod force distribution, the safety factor of the tower crane's tie rod is calculated using the following formula: in Expressed as the safety factor of the tower crane tie rod, a 1 and a 2 They respectively represent the safety weight factors corresponding to the preset tower crane's tie rod load-bearing and force distribution.

[0088] Furthermore, the calculation formula of the tower crane's own safety factor is: Where ξ is the inherent safety factor of the tower crane, b 1 、b 2 、b 3 and b 4They are the safety weight coefficients corresponding to the base, tower, boom and tie rod of the tower crane.

[0089] The tower crane external environment safety monitoring module is used to perform safety monitoring on the external environment of the tower crane and evaluate the external environment safety factor of the tower crane.

[0090] Reference Figure 4 As shown, the external environment safety monitoring module of the tower crane includes a precipitation safety monitoring unit and a wind speed safety monitoring unit;

[0092] E1: Monitor the precipitation of the external environment in the area where the tower crane is located by using a rain gauge, and then obtain the precipitation corresponding to the external environment in the area where the tower crane is located;

[0093] E2: Compare the precipitation corresponding to the external environment in the area where the tower crane is located with the safe precipitation stored in the data cloud platform, and calculate the precipitation safety factor in the area where the tower crane is located. The calculation formula is: Where μ represents the safety factor of precipitation in the area where the tower crane is located, SL″ represents the safe precipitation, and sl′ represents the precipitation corresponding to the external environment in the area where the tower crane is located.

[0094] It should be noted that in the above-mentioned calculation formula for the precipitation safety factor in the area where the tower crane is located, the smaller the precipitation corresponding to the external environment in the area where the tower crane is located, the greater the precipitation safety factor in the area where the tower crane is located, indicating that the precipitation in the area where the tower crane is located is more in line with the safety standards.

[0095] In a specific embodiment of the present invention, the precipitation includes rain, snow, hail, etc. If the precipitation is too large, it will cause impact or squeezing risks to the tower crane, thereby affecting the operating safety of the tower crane.

The calculation formula is: in Expressed as the wind speed safety factor in the area where the tower crane is located, FS max It represents the maximum wind speed that the tower crane can withstand, and fs″ represents the wind speed corresponding to the external environment in the area where the tower crane is located.

[0099] It should be noted that in the above-mentioned calculation formula for the wind speed safety factor in the area where the tower crane is located, the smaller the wind speed corresponding to the external environment in the area where the tower crane is located, the greater the wind speed safety factor in the area where the tower crane is located, indicating that the wind speed in the area where the tower crane is located is more in line with safety standards.

[0100] Furthermore, the calculation formula of the external environment safety factor of the tower crane is: Where σ represents the external environmental safety factor of the tower crane, c 1 and c 2 They are the safety weight values ​​corresponding to the precipitation and wind speed in the area where the tower crane is located.

[0101] In a specific embodiment of the present invention, by using multiple monitoring devices such as inspection drones, high-definition cameras and tension sensors, safety monitoring of the base appearance, tower, boom operation and pull rod bearing of the tower crane is achieved, thereby realizing multi-dimensional safety monitoring of the tower crane, improving the comprehensiveness of the safety monitoring of the tower crane, and providing a reliable basis for the safety assessment of the operation of the tower crane. At the same time, the present invention realizes safety monitoring of the wind speed and precipitation of the external environment in the area where the tower crane is located by using an anemometer and a rain gauge, thereby effectively ensuring the operation safety of the tower crane and improving the operation stability of the tower crane.

[0102] The comprehensive analysis platform is used to comprehensively analyze the operation safety factor of the tower crane based on the monitoring results of the tower crane's own safety monitoring module and the tower crane's external environment safety monitoring module;

[0103] Specifically, the calculation formula for the operation safety factor of the tower crane is: Where τ represents the operating safety factor of the tower crane, κ 1 and κ 2 They respectively represent the safety correction factors corresponding to the preset tower crane itself and the external environment.

[0104] The operation safety warning terminal is used to compare the operation safety factor of the tower crane with a preset standard operation safety factor. If the operation safety factor of the tower crane is lower than the standard operation safety factor, an operation safety warning is issued.
