Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to a concrete worker vibration monitoring device and a system thereof based on BIM technology. Background Art

[0002] The appearance quality of concrete is a direct window for the project to show itself to the outside world. A good appearance of concrete not only represents the project's ability to control quality, but is also a simple and direct way to implement the principle of "quality in the process, quality is paramount". However, in actual engineering projects, there are very few projects that can achieve the ultimate appearance of concrete, mainly because there are too many limitations on the appearance quality of concrete, including but not limited to the workability of concrete, the flatness of the formwork, and the quality of workers' vibration. Among them, the most difficult human factor to control is the quality of workers' vibration of concrete.

[0003] In the actual work of concrete construction, due to the limited number and energy of management personnel, the on-site concrete pouring process is often managed in a semi-free-range manner, or even partially handed over to employees with little experience, making it difficult to control the on-site workers. If the concrete vibration work can be managed in a cloud supervision manner, it will not only reduce the workload of on-site management personnel, but also greatly reduce the occurrence of concrete leakage, over-vibration, uneven vibration and other phenomena caused by human factors, which will greatly help improve the appearance of concrete. If the vibration quality of concrete can be reflected in a graphical way to assist on-site construction management, even novices can manage workers to vibrate the parts that are missed or under-vibrated, reducing the occurrence of concrete honeycombs, holes and other phenomena. Therefore, this application proposes a vibration monitoring device and system for concrete workers based on BIM technology. Summary of the invention

[0033] 1. This BIM-based concrete worker vibration monitoring system, during the construction of the standard floor, sets up multiple AI cameras and base stations in the object positioning system on the floor climbing frame, which mainly monitors the concrete pouring position, vibration position and vibration time. At the same time, a monitoring chip is installed on the ordinary concrete vibrator, and combined with the AI ​​camera and the object positioning base station, the real-time position and vibration frequency information of the concrete vibrator can be monitored. The structural model of the concrete is established using BIM technology, and then the concrete vibration situation is rendered in real time on the structural model through the collected concrete pouring position, concrete vibration position, and concrete vibration time information.

DETAILED DESCRIPTION

[0046] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0047] The embodiments of the present application provide a concrete worker vibration monitoring device and system based on BIM technology, thereby solving the problem that in actual concrete construction work, due to the limited number and energy of management personnel, the on-site concrete pouring process is often managed in a semi-free-range manner, which can easily lead to concrete vibration omission, over-vibration, and uneven vibration due to human factors.

[0048] During the construction of the standard floor, multiple AI cameras and base stations in the object positioning system are set up on the floor climbing frame. Their main function is to monitor the concrete pouring position, vibration position and vibration time. At the same time, a monitoring chip is installed on the ordinary concrete vibrator. Combined with the AI ​​camera and the object positioning base station, the real-time position and vibration frequency information of the concrete vibrator can be monitored. The structural model of the concrete is established using BIM technology, and then the concrete vibration situation is rendered in real time on the structural model through the collected concrete pouring position, concrete vibration position, and concrete vibration time information. At this time, it is convenient for managers to arrange workers to supplement the vibration of the positions that are not vibrated in place, and improve the quality of concrete pouring by reducing human factors. Through the camera mode, managers can monitor the pouring process at any location and guide workers to pour correctly.

[0049] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0050] The embodiment of the present invention discloses concrete worker vibration monitoring equipment and a system thereof based on BIM technology.

[0051] Based on BIM technology, the concrete worker vibration monitoring system is Figure 1 As shown, including:

[0052] An AI camera is installed on a floor climbing frame during standard floor construction, and the AI ​​camera can be used to record the vibrating process of concrete workers;

[0053] AI cameras are monitoring devices that integrate artificial intelligence technology and can intelligently analyze and process monitoring images through image recognition and deep learning technology. In the field of engineering construction, especially in complex operation scenes such as concrete pouring, AI cameras can play an important role in improving construction quality and efficiency by real-time monitoring and analyzing key information such as workers' working status and concrete pouring location.

[0054] Object positioning system, which uses UWB positioning technology in conjunction with AI cameras to monitor the concrete pouring location, vibration position and vibration time, and uses BIM technology to model the concrete construction and render the concrete vibration status in real time on the structural model;

[0055] UWB (Ultra-Wideband) positioning technology is a high-speed, low-power, high-capacity wireless communication technology that transmits data by sending and receiving extremely narrow pulses at or below the nanosecond level. Using UWB positioning technology, the system can accurately locate and monitor the concrete pouring site, vibration position, and vibration time.

[0056] BIM technology uses three-dimensional models to represent buildings, intuitively displaying the shape, spatial structure and internal structure of the building. The BIM model not only contains the geometric shape information of the building, but also contains the material, properties, cost and other information of each component of the building, as well as information on the design, construction and operation and maintenance stages of the building. After using BIM technology to model the concrete construction and rendering the concrete vibration status in real time on the structural model, it is more convenient to view the overall concrete pouring and vibration status.

[0057] An intelligent vibrating rod is equipped with a positioning and monitoring chip, which is combined with an object positioning system to monitor the accurate spatial position, vibration duration and vibration frequency parameters of the vibration.

[0058] The built-in positioning chip of the smart vibrator is based on UWB (ultra-wideband) positioning technology, which has the characteristics of high precision and strong anti-interference ability. By cooperating with the object positioning system, the accurate spatial position of the vibrator at the construction site can be obtained in real time to ensure that the vibration operation is carried out according to the design requirements.

[0059] The built-in monitoring chip of the smart vibrator is responsible for recording and analyzing the vibration duration and vibration frequency parameters of the vibrator. Through the built-in high-precision sensors and algorithms, it can monitor and feedback the key data of the vibration operation in real time.

[0060] Furthermore, the object positioning system includes:

[0061] Base station and tag, the base station communicates with the tag through UWB positioning signal, and the on-site construction personnel wear the tag, the tag transmits UWB signal and communicates with the base station, so that the tag itself is located;

[0062] Positioning engine: the base station sends the original data to the positioning engine in real time through the network, and the positioning engine runs the positioning algorithm to calculate the coordinate position of the positioning tag in real time;

[0063] A workstation presents the tag coordinates calculated by the positioning engine and displays a structural model constructed using BIM technology.

[0064] The workstation collects data from AI cameras and smart vibrators and inputs them into the workstation in real time through the base station for positioning objects. It makes analysis and judgment based on the collected video images and monitoring data. The structural model is rendered in real time using BIM technology, where the base station transmits real-time data and the intranet directly generates data to avoid delays caused by network instability. The final data is then uploaded through the network.

[0065] During the construction of the standard floor, multiple AI cameras and base stations in the object positioning system are set up on the floor climbing frame. Their main function is to monitor the concrete pouring position, vibration position and vibration time. At the same time, a monitoring chip is installed on the ordinary concrete vibrator. Combined with the AI ​​camera and the object positioning base station, the real-time position and vibration frequency information of the concrete vibrator can be monitored. The structural model of the concrete is established using BIM technology, and then the concrete vibration situation is rendered in real time on the structural model through the collected concrete pouring position, concrete vibration position, and concrete vibration time information. At this time, it is convenient for managers to arrange workers to supplement the vibration of the positions that are not vibrated in place, and improve the quality of concrete pouring by reducing human factors. Through the camera mode, managers can monitor the pouring process at any location and guide workers to pour correctly.

[0066] Furthermore, it is possible to use only AI cameras to synthesize the plane layout through multi-point camera shooting, display the positions of planes that are not vibrated into place, reduce the modeling process of BIM technology, and improve monitoring efficiency.

[0067] Based on BIM technology, concrete workers vibration monitoring equipment, according to the attached Figure 2-8 As shown, the AI ​​camera includes an imaging unit 1, an adjusting unit 2 and a clamping unit 3. The adjusting unit 2 is installed at the bottom of the imaging unit 1, and the end of the adjusting unit 2 is connected to the clamping unit 3. The imaging unit 1 can be installed on a floor climbing frame in standard floor construction through the adjusting unit 2 and the clamping unit 3.

[0068] The adjustment unit 2 comprises:

[0069] A mounting plate 21, the mounting plate 21 is mounted on the bottom of the camera unit 1, and an extension component 22 is fixedly mounted on the bottom of the mounting plate 21;

[0070] The rotating disk 23 has two sides connected to the extension assembly 22 and the clamping unit 3 respectively, and a rotating assembly 24 is installed between the rotating disk 23 and the extension assembly 22 .

[0071] During use, because it is necessary to carry out construction on different standard floors, the clamping unit 3 can be used to facilitate clamping it on the rod of the floor climbing frame, and it is also convenient to disassemble it and adjust its installation position. In addition, multiple AI cameras will be installed around the floor climbing frame during construction on the same standard floor, and the rods at different positions may be set as horizontal rods, vertical rods and diagonal rods. At this time, the adjustment unit 2 can be used to adjust the relative angle and spacing between the camera unit 1 and the clamping unit 3, so that the camera unit 1 can be conveniently set at different positions and be in a horizontal state, so as to facilitate monitoring of the construction process of concrete workers.

[0072] Furthermore, the camera unit 1 includes a camera head 11 , a body 12 and a base 13 , and the body 12 is disposed between the camera head 11 and the base 13 .

[0073] Specifically disclosed, the extension assembly 22 includes:

[0074] A square tube 221, an extension bar 222 is movably inserted inside the square tube 221, and the end of the extension bar 222 extends outward and is fixedly connected to the bottom of the mounting plate 21;

[0075] The extension groove 223 is opened through the outer side of the square tube 221 , and a positioning bolt is installed at the end of the extension bar 222 . The end of the positioning bolt extends outward through the extension groove 223 and is threadedly connected with a positioning nut, and the positioning nut is tightly against the outer side of the square tube 221 .

[0076] During use, the positioning nut is rotated to separate it from the outer side of the square tube 221. At this time, the extension bar 222 can be pulled to move, and the positioning bolt at its end moves accordingly, so that the distance between the clamping unit 3 and the camera unit 1 can be adjusted, and then the positioning nut is rotated to make it tightly against the outer side of the square tube 221, so that the position of the clamping unit 3 and the camera unit 1 can be fixed.

[0077] Specifically disclosed, the rotating assembly 24 includes:

[0078] A fixed seat 241, one side of the fixed seat 241 is fixedly connected to the end of the square tube 221, and the other side of the fixed seat 241 is rotatably connected to the rotating disk 23, and a plurality of fixed blocks 242 are installed on the outer side of the fixed seat 241;

[0079] The positioning ring 243 is fixedly mounted on the sides of the plurality of fixing blocks 242 , and the internal thread of the positioning ring 243 is connected with the rotating ring 244 .

[0080] Furthermore, a plurality of extrusion grooves 245 are formed inside the fixed block 242, a movable groove 246 is formed inside the positioning ring 243, and a plurality of connecting holes 247 are formed on a side of the positioning ring 243 close to the fixed block 242, and the plurality of extrusion grooves 245 are respectively connected to the movable groove 246 through the plurality of connecting holes 247.

[0082] When it is necessary to rotate the relative angle between the clamping unit 3 and the camera unit 1, first rotate the rotating ring 244. Since the rotating ring 244 is connected to the internal thread of the positioning ring 243, one side of the rotating ring 244 can push the extrusion ring 249 to move inside the positioning ring 243, so that the side of the extrusion ring 249 no longer squeezes the multiple extrusion blocks 248, and the multiple extrusion blocks 248 cannot fix the position of the rotating disk 23. At this time, the rotating disk 23 and the clamping unit 3 can be rotated until they are rotated to a suitable angle. At this time, the rotating ring 244 is rotated in the opposite direction, so that the side of the extrusion ring 249 pushes the ends of the multiple extrusion blocks 248 to tightly abut against the side of the rotating disk 23, thereby fixing the position of the rotating disk 23 and the clamping unit 3, and can be adjusted according to the rod at the installation position, which is more suitable for use on construction sites.
