Description

TECHNICAL FIELD

[0001] The application relates to the technical field of building construction, in particular to a visual construction management monitoring device and method based on BIM+AI. BACKGROUND

[0002] BIM is a building information modeling technology, which uses a three-dimensional digital model to represent the physical and functional characteristics of a building, infrastructure or environment. BIM technology allows information sharing, collaboration and decision support throughout the entire building life cycle from design, construction to operation and maintenance. AI, namely artificial intelligence, is an important driving force for the new round of technological revolution and industrial reform, and is a new technical science for researching and developing a new application system for simulating, extending and expanding human intelligence. In the cleaning process of the existing construction management monitoring device, the camera completes wiping by rotating the contact upper end of the fiber roller, and the flat camera device cannot completely contact the erected fiber roller, so that the fiber roller cannot fully contact the camera device, causing the wiping effect of the camera device to be reduced, affecting data collection, and affecting BIM model construction and subsequent AI calculation. At the same time, the existing device cannot intelligently identify safety hazards, quality problems and progress deviations in the construction process, and cannot monitor and manage in real time, thereby affecting the smooth progress of the project. SUMMARY

[0003] The purpose of the application is to provide a visual construction management monitoring device and method based on BIM+AI, which can make the fiber roller adhere to the camera device adjusted in rotation by driving the second motor, extending and retracting the hydraulic telescopic rod, and damping the shock absorber. One of the fiber rollers can independently rotate after being driven by the fourth motor, which can further improve the cleaning effect of the camera device. It can intelligently identify safety hazards, quality problems and progress deviations in the construction process, and monitor and manage in real time, providing a strong guarantee for the smooth progress of the project, and solving the problems raised in the above background technology.

[0007] Preferably, the lower ends of the connecting frames are welded with lower protection sheets on both sides, the outer wall of the camera device is provided with a third motor towards one of the lower protection sheets, and the outer wall of the camera device is rotationally connected with the other lower protection sheet through a second damping shaft.

[0008] Preferably, monitoring cavities are arranged on both sides between the two lower protection sheets.

[0009] Preferably, the upper end of the second motor is provided with a connecting rod.

[0010] Preferably, the inside of the connecting rod is provided with a first motor for output, and the output shaft of the first motor is fixedly connected with the connecting frame.

[0012] A visual construction management monitoring method based on BIM+AI, comprising the following steps:

[0013] S1: The position and orientation of the camera device are adjusted by starting the motor and the hydraulic telescopic rod, for omnidirectional acquisition of real-time pictures;

[0014] S2: The acquired real-time images are sent to the AI system platform and the BIM system platform through the data transmission module;

[0016] Compared with the prior art, the beneficial effects of the present application are as follows:

[0017] 1. The camera device of the present invention is driven to rotate by starting a third motor. After rotating around the second damping axis, the camera device will face the fiber roller and be parallel to the lower end of the fiber roller. After the camera device rotates, the extension and retraction of the hydraulic telescopic rod can actively push the fiber roller to fully contact the camera device. During the contact process between the fiber roller and the camera device, the shock absorber will dampen and adapt, reducing the damage to the camera device when cleaning dust. On the other hand, the second motor will start at the same time as the hydraulic telescopic rod extends, driving the fiber roller in contact with the camera device to rotate, further improving the cleaning effect of the camera device when adapted. Finally, among the five fiber rollers that are evenly distributed laterally inside the connecting frame, one fiber roller will be output and rotated by a fourth motor, which can further improve the cleaning effect of the camera device and avoid the problem of poor cleaning effect caused by the fixed fiber roller.

[0018] 2. This invention constructs a detailed 3D model of the project using BIM modeling, enabling accurate expression and visualization of project information. Simultaneously, by using sensors and cameras, combined with AI algorithms, it can intelligently identify safety hazards, quality issues, and schedule deviations during construction, allowing for real-time monitoring and management. Through data acquisition methods such as video surveillance systems and sensor networks, the equipment can collect various data from the construction site in real time, and use AI algorithms for data analysis and processing to generate visual reports, providing strong support for the smooth progress of the project and offering a completely new solution for building construction management.

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Please see Figures 1-4 This embodiment provides a BIM+AI-based visual construction management monitoring device, including a camera device 9 for monitoring. A connecting frame 5 is provided at the upper end of the camera device 9, and a second motor 8 is provided at the upper end of the connecting frame 5. The start of the second motor 8 drives the lower end of the connected hydraulic telescopic rod 10, shock absorber 11, connecting frame 12, and fiber roller 13 to rotate. The rotation of the fiber roller 13 actively brings it into contact with the camera device 9 to be cleaned, enabling efficient cleaning of the camera device 9. A hydraulic telescopic mechanism is provided at one end of the output shaft of the second motor 8. The hydraulic telescopic rod 10 can adjust the horizontal position of the shock absorber 11, the connecting frame 12, and the fiber roller 13 by extending and retracting, so that the fiber roller 13 can fully contact the camera device 9 after rotation, thereby improving the cleaning effect of the camera device 9. A shock absorber 11 is provided at one end of the hydraulic telescopic rod 10 to buffer the fiber roller 13 during the extension and retraction process. When the shock absorber 11 is used for shock absorption, it can prevent the fiber roller 13 from colliding with the camera device 9 and damaging the camera device 9 after the hydraulic telescopic rod 10 extends and retracts.

[0026] A connecting frame 12 is provided at one end of the shock absorber 11. Five fiber rollers 13 are evenly distributed horizontally inside the connecting frame 12. The connecting frame 12 can connect and support the five fiber rollers 13, so that the hydraulic telescopic rod 10 can synchronously drive the five fiber rollers 13 to adjust their horizontal positions. A fourth motor 16 is provided at one end of one of the fiber rollers 13. The fourth motor 16 is located on one side outside the connecting frame 12. The outer wall of the fourth motor 16 is fixedly connected to the outer wall of the connecting frame 12 by bolts. The fiber roller 13 can be driven to rotate independently when the second motor 8 and the hydraulic telescopic rod 10 are output.

[0027] Lower protective plates 6 are welded to both sides of the lower end of the connecting frame 5. A third motor 15 is installed on the outer wall of the camera device 9 facing one of the lower protective plates 6. The outer wall of the camera device 9 and the other lower protective plate 6 are rotatably connected by a second damping shaft 14. The output of the third motor 15 can make the camera device 9 rotate, so that the camera device 9 rotates around the second damping shaft 14 as the center, so that the camera device 9 adjusts its orientation so that it faces the fiber roller 13 and is contacted and cleaned.

[0028] Monitoring chambers 7 are provided on both sides between the two lower protective plates 6. Driven by the third motor 15, the camera device 9 can be directed toward the monitoring chamber 7, so that the camera device 9 can monitor the building being decorated in the direction of the monitoring chamber 7. The camera device 9 can identify and construct a detailed three-dimensional model of the project from the BIM model. Combined with AI technology, it can intelligently identify safety hazards, quality problems and schedule deviations in the construction process. The protruding monitoring chamber 7 can also restrict the liquid flowing outside the connecting frame 5, avoiding frequent contact of rainwater with the camera device 9.

[0029] The upper end of the second motor 8 is provided with a connecting rod 2, and the inside of the connecting rod 2 is provided with a first motor 4 for output. The output shaft of the first motor 4 is fixedly connected to the connecting frame 5. The camera device 9 suspended at the lower end can be rotated through the output shaft of the first motor 4, so that the camera device 9 rotates around the output shaft of the first motor 4 as the center, further adapting to monitoring in different directions.

[0030] One end of the connecting rod 2 is provided with a connecting piece 1. The four corners of the connecting piece 1 are reserved with through holes. Through the reserved through holes, the connecting piece 1 can be bolted through and installed on the wall. The connecting piece 1 and one end of the connecting rod 2 are rotatably connected by a first damping shaft 3. The connection of the first damping shaft 3 can be used to further adjust the connecting rod 2 and adjust the orientation of the camera device 9 suspended at the lower end to adapt to different installation positions of the camera device 9.

[0031] The camera device includes at least one camera and one central processing unit. The central processing unit is equipped with an image acquisition module and a data transmission module. The image acquisition module is used to acquire real-time monitoring images from the camera, and the data transmission module is used to send the acquired images to the AI ​​system platform and the BIM system platform. The AI ​​system platform is used to perform real-time analysis of the monitoring images to identify and warn of abnormal behavior, and the BIM system platform is used to construct a detailed three-dimensional model of the project to achieve accurate expression and visualization of project information.

[0032] Working principle: During use, the camera device 9 monitors the orientation position, and AI collects data and constructs a BIM model. The third motor 15 is activated, causing the camera device 9 to rotate around the second damping shaft 14, aligning it with the fiber roller 13. Once the AI ​​detects the camera device 9's rotation, the second motor 8 and the hydraulic telescopic rod 10 are activated simultaneously. The hydraulic telescopic rod 10 extends, bringing the fiber roller 13 into contact with the camera device 9. The activation of the second motor 8 causes the fiber roller 13 to move in the direction of its input. The output shaft rotates in a circle. During the cleaning process of the contact camera device 9, the fourth motor 16 will start and drive one of the fiber rollers 13 to rotate. The fiber roller 13 will rotate around the output shaft of the fourth motor 16 as a circle, which will further clean the camera device 9. After the camera device 9 is cleaned, the camera device 9 and the fiber roller 13 will be reset. By using the camera device 9 to monitor the project and combining it with AI technology, safety hazards, quality problems and progress deviations in the construction process can be identified.

[0033] To further illustrate this invention, a BIM+AI-based visual construction management and monitoring method is also provided, comprising the following steps:

[0034] S1: The position and orientation of the camera device 9 are adjusted by starting the motor and the hydraulic telescopic rod 10, so as to collect real-time images from all directions;

[0035] S2: The acquired real-time images are sent to the AI ​​system platform and the BIM system platform via the data transmission module;

[0036] S3: The AI ​​system platform performs real-time analysis of the monitoring screen to identify and warn of abnormal behaviors in the project. At the same time, the BIM system platform constructs a three-dimensional model of the project to achieve accurate expression and visualization of project information.

[0037] In summary, this invention, through the driving of a second motor, the extension and retraction of a hydraulic telescopic rod, and the damping of a shock absorber, allows the fiber roller to conform to and rotate the adjusted camera device, contacting and cleaning it. Simultaneously, one of the fiber rollers rotates independently via a fourth motor, further improving the cleaning effect of the camera device. By constructing a detailed 3D model of the project using BIM, accurate expression and visualization of project information are achieved. Furthermore, by using sensors and cameras, combined with AI algorithms, the device can intelligently identify safety hazards, quality issues, and schedule deviations during construction, enabling real-time monitoring and management. Through data acquisition methods such as video surveillance systems and sensor networks, the device can collect various data from the construction site in real time and use AI algorithms for data analysis and processing to generate visual reports, providing strong support for the smooth progress of the project and offering a novel solution for construction management.
