Description

Technical Field

[0001] The invention belongs to the technical field of safety monitoring, and in particular is an Internet-based reservoir dam construction safety monitoring system. Background Art

[0002] As an important water conservancy infrastructure, the safety of reservoir dams is directly related to the safety of people's lives and property and economic and social stability. During the construction of reservoir dams, if the construction safety management is not in place, various safety accidents may occur, causing casualties and property losses. Therefore, ensuring the safety of reservoir dam construction is an important part of ensuring social harmony and stability.

[0003] The traditional reservoir dam construction safety monitoring system has the following problems: First, the traditional reservoir dam construction safety monitoring system cannot comprehensively collect the damage, cracks and displacement of the surface of the reservoir dam corresponding to the constructed main body during the reservoir dam construction process. It simply collects the current damage status of the reservoir dam through manual monitoring, relies on manual decision-making and manual operation, lacks sufficient intelligent support, is inefficient and prone to errors.

[0004] Second, lifting equipment plays an important role in the construction of reservoir dams. The construction safety of lifting equipment is directly related to whether the construction of reservoir dams can be completed smoothly. The traditional reservoir dam construction safety monitoring system does not collect data on lifting equipment during the lifting process, and does not evaluate the equipment safety of the lifting equipment itself and the safety of cargo placement. This is not conducive to the construction of reservoir dams and has great safety hazards.

[0005] Third, during the construction process of the reservoir dam, drainage operations are required to manage and control the water level and water pressure. The traditional reservoir dam construction safety monitoring system cannot provide drainage-related data and monitoring functions, and cannot meet the drainage needs during the construction process. When the reservoir dam is seriously flooded, it will cause partial damage to the reservoir dam and delay the construction progress of the reservoir dam. Summary of the invention

[0047] The damage degree analysis of the constructed main body of the reservoir dam is as follows: the 3D model of the constructed main body of the reservoir dam is compared with the 3D model corresponding to the design drawing of the reservoir dam, and all non-overlapping areas of the two are marked as damaged areas. The volume of all non-overlapping areas is obtained by measurement and recorded as θ g , g represents the number corresponding to the g-th damaged area, g = 1, 2, ..., t.

[0048] Obtain an image of the main surface of the reservoir dam corresponding to the construction, obtain the grayscale image of the main surface of the reservoir dam corresponding to the construction through grayscale processing technology, and obtain the area corresponding to each crack on the main surface of the reservoir dam corresponding to the construction, which is recorded as c j , j represents the number corresponding to the jth crack, j = 1, 2, ..., m, through the formula The damage degree φ of the reservoir dam corresponding to the constructed body is obtained, c0 represents the reference area corresponding to the surface cracks of the preset reservoir dam corresponding to the constructed body, θ0 represents the allowable damage volume of the preset reservoir dam corresponding to the constructed body, m represents the number of surface cracks of the reservoir dam corresponding to the constructed body, t represents the number of damaged areas on the surface of the reservoir dam corresponding to the constructed body, and e is a natural constant.

[0049] It should be noted that the area corresponding to each crack on the surface of the constructed main body of the reservoir dam is obtained by extracting each pixel point from the grayscale image of the constructed main body surface of the reservoir dam, and obtaining the grayscale value of each pixel point in the grayscale image of the constructed main body surface of the reservoir dam. If the grayscale value of each pixel point in the grayscale image of the constructed main body surface of the reservoir dam is less than the grayscale value threshold of the pixel point in the grayscale image corresponding to the surface of the reservoir dam, the pixel point is marked as an edge point, the position of each edge point is counted, and each edge point is connected with the edge point at its adjacent position to form each largest closed image contour, and each closed image contour is recorded as a crack, and the area of ​​each crack is obtained according to the number of pixels corresponding to each crack.

[0059] It should be noted that the number of times the lifting equipment shakes each time the cargo is lifted is obtained as follows: obtain the vertical offset angles of the lifting equipment in each video of the cargo lifting, compare the vertical offset angles of the lifting equipment in each video of the cargo lifting with the preset allowable offset angle, screen out the vertical offset angles of the lifting equipment in each video of the cargo lifting that are greater than the allowable offset angle, and record them as the reference offset angles of the lifting equipment in each video of the cargo lifting, count the time points corresponding to the images to which the reference offset angles in each video of the cargo lifting belong, sort the time points according to the sorted reference offset angles of the lifting equipment in each video of the cargo lifting, and use the time points of the sorted reference offset angles and the adjacent reference offset angle time points to form a video time period, count each video time period, and if there is an image with a vertical offset angle of 0 in a certain video time period, add 1 to the number of times the lifting equipment shakes in that lifting video, and then count the number of times the lifting equipment shakes in each lifting video.

[0062] It should be supplemented that, the present invention obtains the construction safety assessment coefficient of the lifting equipment and evaluates the construction safety status of the lifting equipment by analyzing the equipment posture data and cargo placement data of the lifting equipment, thereby improving the accuracy of construction safety monitoring, greatly reducing the safety hazards of the lifting equipment during use, and improving the safety of the lifted cargo. The safety monitoring of the lifting equipment can help discover and eliminate lifting equipment failures and avoid construction delays caused by lifting equipment failures.

[0069] It should be noted that the method for obtaining the tolerable pressure of each water level layer area corresponding to the constructed main body of the reservoir dam is as follows: the corresponding construction time of each water level layer area corresponding to the constructed main body of the reservoir dam is obtained through the corresponding construction time of each water level layer area, and the area of ​​each water level layer area is obtained according to the three-dimensional model of the constructed main body of the reservoir dam, and the area is obtained by multiplying it with the time required for the dam main body per unit area to reach the safety and solidity, and the time required for each water level layer area to reach the safety and solidity is obtained, and the formula is used to calculate the time required for each water level layer area to reach the safety and solidity. Get the solidity R of the reservoir dam corresponding to each water level height layer area of ​​the built main body h , R′ 安 It is expressed as the safety and solidity of the dam body per unit area, T h It is expressed as the construction time corresponding to the h-th water level layer area, T′ hIt is expressed as the time required for the hth water level layer area to reach a safe and solid level. By comparing the solidity of the reservoir dam corresponding to each water level layer area of ​​the constructed body with the preset reservoir dam corresponding to each solidity range's tolerable pressure, the tolerable pressure of the reservoir dam corresponding to each water level layer area of ​​the constructed body is screened out.

[0070] Get the water flow velocity V of each water level layer area of ​​the reservoir dam corresponding to the built main body h .

When the drainage demand coefficient of the reservoir dam corresponding to the constructed body is greater than or equal to the preset minimum drainage demand coefficient of the reservoir dam corresponding to the constructed body, the reservoir dam is drained.

[0078] It should be noted that when a reservoir dam is draining water, when the water level of the reservoir dam corresponding to the constructed main body is less than or equal to the water level for stopping drainage, the reservoir dam will stop draining water.

[0079] It should be noted that the method for obtaining the height of the water level for stopping drainage is: extracting from the database the maximum distance difference between the safe water level of the constructed body of the reservoir dam and the safe distance range of the height of the reservoir dam body, record it as H″, and obtain the height of the water level H1 for stopping drainage of the constructed body of the reservoir dam corresponding to the constructed body through the formula H1=HH″.

[0080] The database is used to store the initial position coordinates of each monitoring device deployed on the constructed body corresponding to the reservoir dam, store the standard angle between the lifting equipment and the horizontal ground, store the distance difference between the safe water level of the constructed body corresponding to the reservoir dam and the height of the reservoir dam body, and store the construction time and corresponding area of ​​each water level height layer area corresponding to the constructed body of the reservoir dam.
