Description

Technical Field

[0001] The present invention belongs to the technical field of water conservancy and hydropower engineering information system construction, and specifically relates to an engineering safety visualization monitoring method based on a monitoring instrument BIM model. Background Art

[0002] Engineering safety monitoring is an important measure to monitor and master the operating status of hydraulic structures in hydropower stations. By obtaining monitoring data information, timely processing and analysis, it provides a basis for mastering the operating status of the dam and evaluating whether the dam is safe. Dam safety monitoring includes inspections of the dam body and ancillary facilities, deformation monitoring, seepage and pressure monitoring, stress and strain, and environmental quality monitoring. According to the differences in the level and scale of the project, different monitoring sections and monitoring accuracies are set up and different numbers of monitoring instruments are installed and arranged.

[0003] Currently, most hydropower projects have implemented or completed the safety monitoring automation system. After obtaining the original monitoring data from the monitoring instruments, the technical personnel evaluate the safety status of the dam based on the calculated monitoring results. However, due to the complex structure of the dam project, the monitoring results involve many factors, the instruments buried inside the dam body are invisible, the monitoring layout diagram is highly professional and difficult to read, and it is not easy to find the patterns of monitoring results in complex engineering parts. Therefore, the professional requirements and experience requirements for engineering personnel are very high, the monitoring results analysis time is long, and omissions and misjudgments are prone to occur.

[0004] At present, the monitoring system of hydropower projects is based on the display of flat monitoring information. Managers cannot accurately and quickly query the basic situation of monitoring equipment, and cannot timely and clearly grasp all the information of relevant monitoring instruments or measuring points, such as spatial points, distribution status of surrounding monitoring instruments, load or deformation characteristic direction corresponding to monitoring data, installation and construction process information, etc. The Chinese patent, application number CN116304245A, solves the problems of abstract and non-intuitive monitoring results, difficult display of monitoring locations, and dependence of monitoring conclusions on personnel experience by integrating monitoring scene loading module, scene layout module, real-time monitoring data request module and monitoring results visualization module, effectively improving the efficiency and accuracy of complex engineering monitoring. However, it does not involve technical issues such as the creation of BIM models and spatial positioning of monitoring instruments. Summary of the invention

[0005] The purpose of the present invention is to address the problem of low efficiency and accuracy of safety engineering monitoring caused by the inability of existing hydropower engineering monitoring systems to timely and clearly grasp the relevant information of relevant monitoring instruments or measuring points. A method for visual monitoring of engineering safety based on the BIM model of monitoring instruments is proposed. By spatially locating the safety monitoring instrument model loaded into the model library, BIM model creation is realized. Based on the BIM model carrier of the safety monitoring instrument, attributes such as coding, production information, and construction information are given to build a safety monitoring instrument database. The construction of a visual three-dimensional model and its attached database from the spatial dimension can be realized, which can significantly improve the intuitive understanding of safety monitoring and data processing application capabilities of power station operation and maintenance personnel and monitoring data compilers.

[0075] Furthermore, Example 2 is an extension of Example 1, and is specifically as follows: Figure 1 As shown, including:

[0076] S1: Build a three-dimensional spatial installation model library of typical safety monitoring instruments as an online resource call.

[0077] S1-1: Safety monitoring instruments are classified according to their product size, shape, monitoring mode, monitoring object / content, etc., and can be divided into single-point safety monitoring instruments, surface safety monitoring instruments, and linear safety monitoring instruments; corresponding three-dimensional models of safety monitoring instruments are created by category; during the creation of the three-dimensional model of the safety monitoring instrument, variable associated parameters are set in combination with the appearance size; for example, the length of the multi-point displacement meter in the direction of action can be set as a variable associated parameter. When the value of the variable associated parameter is adjusted, the model length of the multi-point displacement meter changes automatically, realizing the parametric change of the instrument model size, length and other dimensions, and the model geometric accuracy meets the G2 accuracy requirements.

[0078] S1-2: Construct spatial positioning and layout parameters based on the three-dimensional model of the safety monitoring instrument. The spatial positioning and layout parameters are used to accurately position the three-dimensional model of the safety monitoring instrument within the three-dimensional model space to ensure that the position, working surface, working direction, etc. of the safety monitoring instrument are consistent with those actually installed on site.

[0079] like Figure 2 As shown, for single-point safety monitoring instruments, such as piezometers, thermometers, strain gauges, etc., the geometric center point, centroid point or bottom center point of the three-dimensional model of the safety monitoring instrument is used as the spatial positioning point (X0, Y0, Z0) of the three-dimensional model of the safety monitoring instrument.

[0080] like Figure 3 As shown, surface instruments, such as soil pressure gauges, concrete stress gauges, etc., use the working surface of the three-dimensional model of the safety monitoring instrument as the positioning plane (PM0), and the geometric center point or center of mass of the projection of the three-dimensional model of the safety monitoring instrument on the positioning plane as the spatial positioning point (X0, Y0, Z0).

[0081] like Figure 4 As shown, for linear instruments, such as multi-point displacement meters, sedimentation meters, inclinometers, etc., the plane formed by the length direction and Z direction (vertical upward) of the three-dimensional model of the safety monitoring instrument is used as the positioning plane (PM0); the angle between the length direction and the Z direction is used as the positioning angle (JD0, ∈ [0, 180]), the spatial positioning point (X0, Y0, Z0) is used as the origin, and the clockwise direction is positive; the action point of the three-dimensional model of the safety monitoring instrument (one side of the long rod) is used as the spatial positioning point (X0, Y0, Z0). The initial values ​​of the spatial positioning layout parameters of the three-dimensional model of the safety monitoring instrument are all 0 by default.

[0082] S1-3: Integrate the three-dimensional model of the safety monitoring instrument and the spatial positioning and layout parameters as the spatial installation model of the safety monitoring instrument and set it as an online shared resource.

[0083] S2: Spatial arrangement of safety monitoring instruments.

[0084] S2-1: Figure 5 As shown in the figure, a 3D model of a monitoring object, such as a dam or engineering slope, is constructed, and the model origin D0 is determined. The origin can be a feature point near the dam, such as the transverse joint of the middle dam section of the high surface of the dam foundation and the center point of the bottom surface of the engineering slope excavation. If there are multiple monitoring objects in a certain project, the dam origin is used as the overall model origin D0, and the reference points D1 and D2 of other engineering parts (spillway, underground powerhouse and other buildings) are preferably offset by integers (Δx1, Δy1, Δz1) and (Δx2, Δy2, Δz2) along the three directions in space from the overall model origin D0.

[0085] S2-2: At the installation and burial site of the safety monitoring instrument, according to the requirements for the layout of the monitoring instrument installation points, calculate and analyze the distances between the safety monitoring instrument layout position and the engineering site reference point D1 in three directions of space, which are calculated as (X1, Y1, Z1); select the working surface where the safety monitoring instrument is arranged as the positioning plane (PM1); when calculating the positioning angle (JD1) of the safety monitoring instrument, use the working surface where the safety monitoring instrument is arranged as the calculation plane, with the Z direction directly upward as 0°, (X1, Y1, Z1) as the origin, and calculate the positioning angle (JD1) in a clockwise direction.

[0086] S2-3: Load the spatial installation model of the safety monitoring instrument corresponding to the monitoring instrument buried on site into the three-dimensional model space. For different types of instruments, fill in the required spatial positioning point (X0, Y0, H0), positioning plane (PM0) and positioning angle (JD0) data respectively. Spatial positioning point (X0, Y0, H0) = (X1 + Δx1, Y1 + Δy1, H1 + Δz1); positioning plane (PM0) = (PM1); positioning angle (JD0) = (JD1); After the data is filled in, the three-dimensional model of the safety monitoring instrument automatically moves to the accurate spatial position, that is, the spatial layout of the three-dimensional model of the safety monitoring instrument is completed through the above data.

[0087] S3: Input the attribute information of the safety monitoring instrument.

[0088] S3-1: Comprehensively sort out the relevant information of safety monitoring instruments, including the data interface with the safety monitoring automation system (matching data source, data extraction, parsing and conversion procedures, etc.), procurement, production and installation information (manufacturer, model, instrument type, specifications, factory parameters, fixed parameters, installation unit, installation process photos, etc.), burial points (specific spatial coordinate point layout, burial location), etc., to form a standardized hierarchical format list.

[0089] S3-2: Construct the model code of the safety monitoring instrument (which can also be the same as the safety monitoring automation system code), according to the project name, for example, Three Gorges: SX; Xiluodu: XLD—sub-project name, for example, water retaining dam, spillway, diversion tunnel, etc.; Dam, Spillway, Diversion tunnel, etc.—monitoring project type, for example, temperature, seepage, stress-strain, deformation, etc.; Temperature, Seepage, Stress-strain, Deformation, etc.—monitoring instrument category, for example, differential resistance type, vibrating wire type, capacitance type, etc.; Differential resistance type, Vibrating wire type, Capacitance type—monitoring instrument code, as shown in Table 1, for example, external deformation observation pier, stress-free gauge, earth pressure gauge; TPi, Ni, Ei, here in accordance with industry rules—serial number classification, for example, 0001, 0002, 0003... for coding. The code generation and input of the safety monitoring instrument are completed by list selection.

[0090] Table 1 Codes of some typical safety monitoring instruments

[0091] Instrument Name Code External deformation observation pier TP Bypass hole R Strong motion instrument SM Five-way strain gauge set Si No stress gauge Ni Soil displacement meter string TY Earth pressure gauge E Osmometer P Pressure tube UP Liangshuiyan WE Tension line horizontal displacement meter H Multi-point displacement meter Mi Steel bar meter R Crack Meter K thermometer T

[0092] It can be understood that, as shown in Table 2, for example: Three Gorges—dam—temperature—differential resistance type—stress-free meter—0001; the corresponding English code is: SX—Dam—Temperature—Differential resistancetype—Ei—0001. After the Chinese code is generated, the English code is synchronously mapped.

[0093] Table 2 List of standardized hierarchical formats of auxiliary information of safety monitoring instruments

[0094]

[0095]

[0096] S3-3: Based on the three-dimensional model of the safety instruments arranged in the space of S2, the formatted form information of S3-1 and S3-2 is input as the model attribute to realize the association between the model and the data information. At the same time, the code and serial number of the safety monitoring instrument are displayed in the three-dimensional space.

[0097] S4: Construction of dynamic database of safety monitoring instruments.

[0098] S4-1: Lightweight the three-dimensional model of the monitored object and the safety monitoring instrument model to form a lightweight model, and export it together with its attribute information.

[0099] S4-2: According to the standard database construction method, with the lightweight model and attribute information of step S4-1 as the basic data, a dynamic database of safety monitoring instruments is constructed through conceptual design, logical design, physical design, database creation, data import, data operation and other steps.

[0100] S5: Construct a safety monitoring instrument database application platform that integrates BIM models.

[0101] Based on the dynamic database of safety monitoring instruments built by S4, we integrate tools such as 3D visualization engine, graphical forms, data interface, etc. to develop a WEB-side safety monitoring instrument database application platform. The main functions of the platform are as follows:

[0102] (1) Spatial display and query of monitoring points. Based on the three-dimensional entity model of the safety monitoring instrument and its coding information and attribute information, the display is realized within the spatial range. It supports the query of specific information based on the location, model and coverage of the input information, and supports the centering display of the queried safety monitoring instrument model and the display in a specific color.

[0103] (2) Supports the display of safety monitoring instrument models in a group within a specified range around the target safety monitoring instrument model being accessed or queried, such as 5.0m, 10m, 15m, etc., and supports hierarchical range based on this. For example, after screening out safety monitoring instruments within a range of 5.0m, continue to display monitoring instrument models within the ranges of 1.0-2.0m, 2.0-3.0m, 3.0-4.0m, and 4.0m-5.0m in groups; supports further grouping of monitoring items of the same type based on the grouping of safety monitoring instrument models within a specified range around.

[0104] (3) Supports real-time data access between the safety monitoring instrument model and the safety monitoring automated data acquisition and analysis system, supports process line display of monitoring data, supports (2) same-screen display of grouped filtered instrument data, and supports display of multiple process line data linked by grouped filtered instruments in the same chart.

[0105] (4) Combined with the finite element numerical simulation calculation results of the target hydraulic structure, the measurement range of the safety monitoring instrument, the safety monitoring data interval of similar projects, the safety monitoring data analysis and prediction results, etc., set a multi-level warning threshold to achieve a visual warning based on the three-dimensional solid model of the safety monitoring instrument. Warnings are issued through color changes of the monitoring instrument model (for example, turning yellow or red when the monitoring data is close to the threshold) or flashing.

[0106] (5) Supports graphical display of monitoring data. For example, five piezometers are buried along the foundation surface of a dam from upstream to downstream in a monitoring section. When the five piezometers are selected for grouping, the data can be displayed in a distributed manner on the monitoring section and connected into a curve.

The scope of the present invention includes but is not limited to the present specific embodiments. All equivalent changes made in accordance with the shape, structure, and method of the present invention are within the protection scope of the present invention.
