Description

Technical Field

[0001] The present invention relates to the technical field of digital modeling, and more specifically, to a sand-laying ship backfill monitoring system and method based on a BIM model. Background Art

[0002] BIM, or Building Information Model, is a digital technology used in the process of building design, construction and operation. Based on three-dimensional modeling, by integrating various information of construction projects, the management and coordination of the entire life cycle of the project can be achieved. With the improvement of computer technology processing capabilities and the enhancement of software functions, BIM technology has begun to expand to more complex construction projects and engineering fields, and has been applied in water conservancy projects, water transport projects and other fields. Sand-laying ship backfilling operation is an important construction content in the fields of water conservancy projects, water transport projects and other fields. Traditional backfilling operation monitoring methods often have problems such as insufficient accuracy and poor real-time performance, which makes it difficult to meet the needs of modern engineering for efficient and precise construction. Therefore, a sand-laying ship backfilling monitoring system and method based on the BIM model came into being, aiming to improve the monitoring accuracy and real-time performance of backfilling operations through digital means, and provide strong support for engineering construction.

[0003] The traditional sand-laying ship backfill monitoring system includes a data acquisition module, a data transmission module, a data processing and analysis module, a monitoring and management module, and a data storage and backup module. The data acquisition module is used to collect relevant data of the sand-dredging ship, the data transmission module is used to transmit the data collected by the data acquisition module to the monitoring center or relevant management department in real time, the data processing and analysis module is used to analyze and process the data and monitor the operation of the sand-dredging ship, the monitoring and management module is used to monitor the operation of the sand-dredging ship in real time, and provide a management interface for relevant personnel to view and operate, and the data storage and backup module is used to store all data generated by the system, and regularly back up to prevent data loss. The traditional sand-laying ship backfill monitoring system has a simple and intuitive operation process, which can track and record the backfill progress in real time, and provide basic data support for project management and quality control.

[0004] However, it still has some shortcomings in actual use, such as slow response speed. The traditional sand-laying ship backfill monitoring system has a slow response speed due to delays in manual monitoring and data processing, and is unable to respond to changes in the backfill process in a timely manner, resulting in inaccurate backfilling of the sand-laying ship; data collection is not comprehensive enough, and the traditional sand-laying ship backfill monitoring system is unable to fully cover the backfill area, resulting in certain key areas being missed, resulting in the inability to timely discover potential safety hazards and problems.

[0043] The data acquisition module is used to collect the key parameters of the sand paving ship backfill in real time, obtain the key information values ​​of the sand paving ship backfill, and pass the collected data to the BIM model construction module.

[0044] Furthermore, the key parameters of sand paving ship backfill include geographic location and positioning parameters, backfill material parameters, construction vibration parameters, equipment status parameters and environmental monitoring parameters. The collected key parameters of sand paving ship backfill are integrated, the integrated data are cleaned, and the data format is unified to obtain the basic characteristics and distribution of the key parameters of sand paving ship backfill, that is, the key information value of sand paving ship backfill.

[0045] What needs to be specifically explained in this embodiment is that the geographical location and positioning parameters specifically include the latitude and longitude data, elevation data, real-time positioning data and geographical feature data of the sand-laying ship in the backfill operation; the backfill material parameters specifically include the type of material used for backfilling, the particle size and distribution of the backfill material, the density of the backfill material, the moisture content of the backfill material, the compressive strength of the backfill material and the stability index of the backfill material; the construction vibration parameters specifically include the vibration amplitude, vibration frequency, vibration duration, vibration direction and vibration acceleration; the equipment status parameters specifically include the equipment operating time, equipment workload, equipment temperature and equipment energy consumption; the environmental monitoring parameters specifically include air quality parameters, noise intensity, water quality and soil parameters.

[0046] The BIM model building module constructs the BIM model of the sand paving ship backfill operation based on the key information values ​​of the sand paving ship backfill, dynamically updates the BIM model according to the real-time collected data, and passes the data to the construction simulation module.

[0047] Furthermore, constructing the BIM model of the sand-laying ship backfill operation requires establishing a seabed topographic map before the backfill construction, then conducting a digital elevation analysis of the seabed surface, selecting software suitable for constructing the BIM model of water conservancy projects or marine engineering projects, establishing a BIM model, generating a construction model, integrating the key information values ​​of the sand-laying ship backfill operation into the construction model, and dynamically updating the BIM model of the sand-laying ship backfill operation based on the data information collected in real time.

[0048] What needs to be specifically explained in this embodiment is that in order to establish a seabed topographic map before backfilling construction, it is necessary to first collect seabed topographic data, use sonar detection technology, determine the shape of the ocean bottom by sending sound wave signals and measuring the time and intensity of the echo, and ensure that the collected data has sufficiently high accuracy and resolution; perform denoising, data smoothing and data integration on the data; and use three-dimensional modeling technology to establish a three-dimensional model based on the processed seabed topographic data.

[0049] What needs to be specifically explained in this embodiment is that the digital elevation analysis of the seabed surface needs to obtain the elevation data of the seabed through remote sensing images, lidar and other technical means, and pre-process the data, including radiation correction, atmospheric correction and geometric correction, and use the acquired elevation data; generate the DEM of the entire area through the interpolation algorithm, and fully consider the characteristics of the seabed terrain and the data distribution; and perform elevation analysis based on the generated DEM.

[0050] The construction simulation module simulates the sand paving ship backfilling process based on the BIM model and the key information values ​​of the sand paving ship backfilling, obtains the key information values ​​of the sand paving ship construction simulation, and applies it to the actual construction process of the sand paving ship backfilling operation.

[0051] Furthermore, the sand paving ship backfilling process is simulated by performing construction animation simulation through the BIM model of the sand paving ship backfilling operation, and the key information of the sand paving ship backfilling operation process is simulated. During the simulation process, the sand paving ship related parameters are set according to the sand paving ship backfilling key information values, and the data of the construction site is monitored and obtained in real time to verify the correctness of the simulation results. According to the simulation results, the sand paving ship related parameters in the simulated sand paving ship backfilling operation process are adjusted in real time.

[0052] What needs to be specifically explained in this embodiment is that the key information in the simulation of the sand paving ship backfilling process includes key information such as the navigation track, sand unloading position and backfilling speed. In the simulation process, the relevant parameters of the sand paving ship should be set according to the key information value of the sand paving ship backfilling obtained by the data acquisition module. The relevant parameters of the sand paving ship should correspond to the key information value of the sand paving ship backfilling obtained to ensure that it can accurately simulate the sand paving ship backfilling process, guide the navigation and sand unloading operations of the sand paving ship, and ensure the smooth progress of the backfilling process. In addition, the data of the construction site is acquired in real time by combining big data technology, the BIM model of the sand paving ship backfilling operation is optimized, and the relevant parameters of the sand paving ship in the simulation of the sand paving ship backfilling operation are adjusted in real time to improve the accuracy and reliability of the simulation.

[0053] Furthermore, the key information values ​​of the sand-laying ship construction simulation include ship parameters, construction parameters and simulation parameters, among which the ship parameters include ship size, loading capacity and power performance; the construction parameters include sand unloading method, laying speed, sand unloading rate, laying width and thickness, laying uniformity, navigation speed, construction efficiency and sand solidification time; the simulation parameters include simulation accuracy, simulation range and simulation time.

[0054] What needs to be specifically explained in this embodiment is that the ship size in the ship parameters includes the length, width, and draft of the sand paving ship, the loading capacity refers to the loading capacity of the sand paving ship, that is, the amount of sand that can be loaded each time, and the power performance includes the engine power and speed of the sand paving ship; the sand solidification time in the construction parameters refers to the time required for the sand to solidify after laying in order to achieve the expected strength and stability. The solidification time needs to be determined according to the soil characteristics, construction conditions, and the needs of subsequent projects; the simulation accuracy in the simulation parameters includes time accuracy and space accuracy, the simulation range refers to the scope of the construction simulation, including the size of the construction area and the trajectory of the ship's navigation, and the simulation time refers to the time requirements of the construction simulation, including the start time and end time of the simulation.

[0055] The monitoring and analysis module is used to monitor the backfilling operation process of the sand paving ship in real time, obtain the key information value of the sand paving ship construction, and build a sand paving ship work quality analysis model. The sand paving ship work quality analysis model can be used to obtain the sand paving ship work quality evaluation value based on the key information of the sand paving ship construction.

[0056] Furthermore, constructing a sand-laying ship work quality analysis model includes collecting multiple groups of sand-laying ship backfill operation samples in different states for monitoring and collection, and integrating the key information values ​​of the sand-laying ship construction obtained by monitoring and collection into the system operation database. The key information values ​​of the sand-laying ship construction refer to the ship parameters, construction parameters and simulation parameters in the actual sand-laying ship backfill operation, and normalizing the data; performing data analysis and linear fitting on the processed sand-laying ship construction key information values, and obtaining the sand-laying ship work quality evaluation value calculation formula, and obtaining the sand-laying ship work quality evaluation value of the sand-laying ship backfill operation.

[0057] What needs to be specifically explained in this embodiment is that by constructing a sand paving ship work quality analysis model and calculating the sand paving ship work quality evaluation value through the sand paving ship work quality analysis model, the effect of the sand paving ship backfilling operation can be accurately and intuitively reflected. In the process of constructing the sand paving ship work quality analysis model, the selection of sand paving ship backfilling operation samples should cover a sufficient number of types, and the sand paving ship work quality evaluation value calculation formula is obtained through linear fitting, and the calculated sand paving ship work quality evaluation values ​​of different sand paving ship backfilling operation samples are associated with the corresponding sand paving ship backfilling operation effects, and uploaded to the system operation database, so as to facilitate the evaluation of the effect of the sand paving ship backfilling operation through the sand paving ship work quality evaluation value in the subsequent process.

[0058] The early warning module is used to build an early warning model. The standard value of the working quality of the sand paving ship is obtained through the early warning model. The working quality assessment value of the sand paving ship is compared with the standard value of the working quality of the sand paving ship to determine whether the working status of the sand paving ship is abnormal and pass it to the human-computer interaction module.

[0059] Furthermore, an early warning model is constructed by monitoring and analyzing different types of samples that are in a critical state of qualified work quality of sand-laying ship backfill operations, collecting the corresponding key information values ​​of the sand-laying ship construction, and calculating the sand-laying ship work quality assessment value under the critical state, which is the sand-laying ship work quality standard value, and uploading it to the system operation database.

[0060] What needs to be specifically explained in this embodiment is that in order to determine whether the working state of the sand paving ship is abnormal, it is necessary to compare the sand paving ship work quality evaluation value of the sand paving ship backfilling operation with the sand paving ship work quality standard value. When the sand paving ship work quality evaluation value is greater than the sand paving ship work quality standard value, it indicates that the sand paving ship working state is normal and there is no need to adjust the parameters of the sand paving ship backfilling operation. When the sand paving ship work quality evaluation value is less than the sand paving ship work quality standard value, it indicates that the sand paving ship working state is abnormal and it is necessary to adjust the parameters of the sand paving ship backfilling operation, and send an early warning message to the human-computer interaction module to remind relevant staff to take effective measures in time.

[0061] The human-computer interaction module is used to provide a visual interface, display the BIM model of the sand-laying ship backfilling operation in real time, display the relevant parameters and early warning information of the sand-laying ship backfilling operation in real time, and send it to the user information terminal synchronously.

[0062] Furthermore, the visualization interface should include a menu bar, a toolbar, a status bar and a work area, wherein the work area should display in real time the BIM model of the sand paving ship backfilling operation, the key information values ​​of the sand paving ship construction simulation and the key information values ​​of the sand paving ship construction; issue an alarm in time according to the warning information transmitted by the early warning module; and send the information to the user information terminal synchronously.

[0063] What needs to be specifically explained in this embodiment is that the menu bar of the visualization interface provides user navigation and setting options, including file operations, view control, and import and export of files; the toolbar includes commonly used tool buttons, such as zooming in, zooming out, panning, measuring, and marking, which are convenient for users to interact with the interface; the status bar should display the working status, time, and user information of the current sand paving ship backfill operation; the workspace is used to display the BIM model of the sand paving ship backfill operation, the key information values ​​of the sand paving ship construction simulation, and the key information values ​​of the sand paving ship construction, to help managers and operators monitor and evaluate the backfill operation in real time.
