Description

Technical Field

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

[0002] BIM is a building information modeling technology that uses three-dimensional digital models to represent the physical and functional characteristics of buildings, infrastructure or environments. BIM technology allows information sharing, collaborative work and decision support throughout the entire building life cycle from design, construction to operation and maintenance. AI, or artificial intelligence, is an important driving force for the new round of scientific and technological revolution and industrial transformation. It is a new technical science that studies and develops theories, methods, technologies and application systems for simulating, extending and expanding human intelligence. During the cleaning process of the existing construction management monitoring equipment, the camera completes the wiping by rotating the fiber roller at the upper end, and the flat camera device cannot fully contact the installed fiber roller, which makes it easy for the fiber roller to not fully contact the camera device, resulting in a reduced wiping effect of the camera device, affecting data collection, and affecting the construction of the BIM model and subsequent AI calculations; at the same time, the existing equipment cannot intelligently identify safety hazards, quality problems and progress deviations during the construction process, and cannot monitor and manage in real time, thus affecting the smooth progress of the project. Summary of the invention

[0003] The purpose of the present invention is to provide a visual construction management and monitoring device and method based on BIM+AI. Through the drive of the second motor, the extension and retraction of the hydraulic telescopic rod and the damping of the shock absorber, the fiber roller can be fitted with the rotationally adjusted camera device. One of the fiber rollers can be driven by the fourth motor and rotated independently, 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, monitor and manage in real time, provide strong guarantees for the smooth progress of the project, and solve the problems raised in the above-mentioned background technology.

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

[0013] S1: The position and direction of the camera device are adjusted by starting the motor and the hydraulic telescopic rod to collect real-time images in all directions;

[0014] S2: The collected 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 present invention has the following beneficial effects:

[0017] 1. The camera device of the present invention is driven to rotate by starting the third motor. After the camera device is driven to rotate by the third motor and rotates with the second damping axis as the center, it will face the fiber roller and be parallel to the lower end of the fiber roller. After the camera device is rotated by setting and AI recognition, the extension and retraction of the hydraulic telescopic rod can actively push the fiber roller to fully contact the camera device. During the process of the fiber roller contacting the camera device, the shock absorber will perform shock absorption and adaptation, thereby reducing damage to the camera device when cleaning dust; on the other hand, the second motor will be started while the hydraulic telescopic rod is extended, driving the fiber roller contacting the camera device to rotate, thereby further improving the cleaning effect of the camera device under the condition of adaptation; finally, among the five fiber rollers uniformly distributed laterally inside the connecting frame, one of the fiber rollers will be output and rotated separately by the fourth motor, thereby further improving the cleaning effect of the camera device and avoiding the problem of poor cleaning effect of the camera device caused by the fixing of the fiber rollers.

The present invention constructs a detailed three-dimensional model of the project through the BIM model, realizes the accurate expression and visual display of the project information, and at the same time, through the use of sensors, cameras and other equipment, combined with AI algorithms, it can intelligently identify the safety hazards, quality problems and progress deviations in the construction process, and monitor and manage in real time. Through data acquisition methods such as video monitoring systems and sensor networks, the equipment can collect various data on the construction site in real time, and use AI algorithms to analyze and process the data to generate visual reports, which provides a strong guarantee for the smooth progress of the project and provides a new solution for construction management.
