Description

Technical Field

[0001] The present invention relates to the field of terrazzo quality detection, and in particular to an automatic detection device and method for terrazzo construction quality. Background Art

[0002] As an economical, durable, and easy-to-clean building material, terrazzo is widely used in educational buildings, office buildings, and other locations. However, due to non-standard construction methods, terrazzo floors often exhibit quality issues such as excessive porosity, numerous pinholes, poor glossiness, and unevenly exposed gratings. These issues not only affect the aesthetics but can also hinder normal use. To improve the construction quality of terrazzo floors and reduce inspection time and costs, a device that can accurately and efficiently inspect terrazzo construction quality is urgently needed to ensure that terrazzo floors meet relevant standards and requirements.

[0003] Existing terrazzo construction quality inspections rely primarily on manual labor, which is not only inefficient but also susceptible to human factors, resulting in inaccurate test results. Furthermore, existing inspection devices may not fully and objectively reflect the actual construction quality of terrazzo during measurement, making them more prone to errors and omissions, leading to low efficiency and further hindering project progress.

[0018] Furthermore, the driving mechanism includes a motor and a suspension rope wound around a rotating wheel of the motor, and the bottom of the suspension rope is fixedly connected to the horizontal portion of the connecting rod.

[0019] Accordingly, the present invention also provides a method for automatically detecting the construction quality of terrazzo using the automatic detection device for terrazzo construction quality, comprising the following steps:

[0020] Step 1: Set up an automated terrazzo construction quality inspection device. Set up a virtual inspection space corresponding to the terrazzo floor to be inspected in the back-end system. Set up a terrazzo layout diagram and a walking path for the walking cart in the virtual inspection space. The layout diagram includes m rows and n columns of terrazzo, and the walking path is set along the middle boundary between two columns of terrazzo.

[0022] Step 3: The main control module sends a command to the driving mechanism, causing the driving mechanism to drive the connecting rod to move downward along the sliding track, so that the hollow drum hammer strikes the terrazzo; the sound monitoring module monitors the sound data of the hollow drum hammer striking the terrazzo and transmits it to the main control module;

[0023] Step 4: The main control module determines whether the terrazzo is hollow based on the sound data sent by the sound monitoring module, and marks the corresponding virtual terrazzo block as hollow if it is hollow; the main control module sends an instruction to the driving mechanism, causing the driving mechanism to drive the connecting rod to move upward along the sliding track, so that the hollow hammer moves a distance away from the terrazzo;

[0024] Step 5: The main control module sends a command to the trolley control module to make the trolley move to the boundary of the next drainage grindstone and repeat steps 3 and 4;

[0025] Step 6. After the trolley moves to the boundary of the last row of terrazzo in the first and second columns and the detection device has completed the detection, the main control module sends an instruction to the trolley control module to make the trolley move horizontally to the boundary of the next column of terrazzo, and repeat steps 3 to 5 until all terrazzo have been detected.

Therefore, the terrazzo construction quality automatic detection device can quickly and accurately determine whether the terrazzo is hollow, and the movement of the trolley and the detection work of the monitoring system can be automated, thereby improving the accuracy of recognition and work efficiency. When the hollowing hammer is equipped with a first level monitoring device, the first level monitoring device can monitor the levelness of the upper surface of the hollowing hammer. The main control module can collect angle data from the first level monitoring device to determine whether the terrazzo is tilted. When the detection system also includes a displacement monitoring device, the displacement monitoring device can measure the vertical displacement data of the connecting rod. The main control module can use this displacement data to determine whether there is a height difference between the terrazzo on both sides of the traveling carriage.

[0044] The following is a detailed description of the automated terrazzo construction quality detection device and method provided by the present invention, with reference to the accompanying drawings and specific embodiments. The advantages and features of the present invention will become more apparent from the following description. It should be noted that the accompanying drawings are highly simplified and not to exact scale, and are intended solely to facilitate and clarify the purpose of illustrating the embodiments of the present invention.

[0045] Example 1

[0046] Combine Figures 1 to 3 As shown, this embodiment provides an automated terrazzo construction quality inspection device comprising a traveling carriage 10, a positioning device 20, a back-end system 30, a detection system 40, and a main control module 50. The positioning device 20 is capable of determining the position of the traveling carriage 10, the back-end system 30 is capable of planning the travel path 33 of the traveling carriage 10, and the detection system 40 is capable of inspecting the quality of the terrazzo on both sides of the traveling carriage 10 as it moves.

[0047] The trolley 10 is driven by a power system and controlled by a trolley control module 11 to follow a predetermined route. The trolley control module 11 is used to control the path of the trolley 10 and also has functions such as command execution and signal transmission. It can receive instructions from the main control module 50 and execute operations, while also feeding back information about the trolley 10 to the main control module 50. The trolley 10 is provided with an adjustable base 12, on which a mounting plate 13 is vertically mounted. Sliding tracks 14 are provided on both sides of the mounting plate 13. The mounting plate 13 and the sliding tracks 14 are used to install a detection system 40.

[0048] The positioning device 20 is used to accurately position the walking vehicle 10 in real time. The positioning device 20 can be implemented by using a positioning base station 22 and a positioning tag 21 (or a positioning chip). Of course, other technologies can also be used. For example, Figure 1 As shown, a positioning base station 22 is set at each corner of the terrazzo area to be inspected, and a positioning tag 21 is installed on the walking vehicle 10. The real-time positioning of the walking vehicle 10 can be achieved through the positioning base station 22 and the positioning tag 21.

[0049] The back-end system 30 can be an on-site server, processor, or control device, or a remote server, processor, or control device, used to present a virtual positioning space and locate and annotate abnormal information. A virtual detection space 31 corresponding to the terrazzo floor 1 to be inspected is provided in the back-end system 30. The virtual detection space 31 is marked with a dotted line with a layout diagram of virtual terrazzo blocks 32. The size and layout of the virtual terrazzo blocks 32 correspond to the size and layout of the terrazzo blocks on the terrazzo floor 1 to be inspected. The walking path 33 of the trolley is marked on the layout diagram of the virtual terrazzo blocks 32. Based on the coordinate information fed back by the positioning device 20, the precise position of the trolley 10 is simulated in the virtual detection space 31.

[0050] The detection system 40 includes a driving mechanism, a connecting rod 43, a universal joint 44, a hollow drum hammer 45 and a sound monitoring module 46. The connecting rods 43 are symmetrically arranged on the two sides of the top of the mounting plate 13, and the driving device is symmetrically arranged. The connecting rod 43 is L-shaped, and one end of the horizontal part is slidably connected to the sliding track 14. The bottom end of the vertical part of the connecting rod 43 is hingedly connected to the hollow drum hammer 45 through the universal joint 44. It can be driven by the driving device to move up and down along the sliding track 14, so that the hollow drum hammer 45 can hit the terrazzo; the sound monitoring module 46 is set on the side of the walking trolley 10 corresponding to the hollow drum hammer 45, to monitor the sound data of the hollow drum hammer 45 hitting the terrazzo. The bottom of the hollow drum hammer 45 is designed as a soft colloid, which is used to hit the terrazzo and make a sound without damaging the terrazzo surface. The sound monitoring module 46 has a sound monitoring function, which is used to collect sound signals when the hollow drum hammer 45 strikes the terrazzo. It also has command execution and signal transmission functions, and can receive instructions from the main control module 50 and execute operations, while also feeding back sound information to the main control module 50. The universal joint 44 ensures that the hollow drum hammer 45 can maintain contact with the terrazzo surface when in contact with the terrazzo.

[0051] The main control module 50 has the functions of receiving information, sending instructions, analyzing and judging, etc. It can collect data fed back by the sound monitoring module 46, the positioning device 20, etc. in real time, and can also send instructions to the trolley control module 11, the driving mechanism, the back-end system 30, etc. and receive their feedback information. The main control module 50 can send instructions to the trolley control module 11 based on the walking path in the back-end system 30, thereby controlling the travel of the walking trolley 10 through the trolley control module 11. The main control module 50 can collect the sound data of the sound monitoring module 46 and judge whether the terrazzo is hollow. When it is judged to be so, the corresponding virtual terrazzo block 32 is marked as hollow in the virtual detection space 31. When the main control module 50 judges whether it is hollow, it can be trained through a large model. When applied, the sound data is input into the large model and the judgment result is directly output to determine whether it is hollow.

[0052] The terrazzo construction quality automatic detection device provided in this embodiment has a virtual detection space 31, an arrangement diagram of virtual terrazzo blocks 32, and a travel path 33 of the trolley 10 set in the back-end system 30. The main control module 50 can send instructions to the trolley control module 11 based on the travel path of the trolley 10 to control the movement of the trolley 10, and the cooperative control drive mechanism drives the connecting rod 43 to move up and down along the sliding track 14, so that the hollowing hammer 45 hits the terrazzo. The sound monitoring module 46 collects sound data and sends it to the main control module 50. The main control module 50 determines whether the terrazzo is hollow based on the sound data. When it is hollow, the corresponding virtual terrazzo block 32 is marked as hollow in the virtual detection space 31. Therefore, the terrazzo construction quality automatic detection device can quickly and accurately determine whether the terrazzo is hollow, and the movement of the trolley 10 and the detection work of the detection system 40 can be automated, thereby improving the accuracy of recognition and work efficiency.

[0053] In a specific embodiment, the detection system 40 further includes a first level monitoring device 47, which is provided on the hollow drum hammer 45 to monitor the horizontality of the upper surface of the hollow drum hammer 45; the main control module 50 is capable of collecting angle data of the first level monitoring device 47 to determine whether the terrazzo is level. For example, the first level monitoring device 47 can be a gravity sensor or an inclinometer, which can measure the horizontal angle of the hollow drum hammer 45. The hollow drum hammer 45 is connected to the connecting rod 43 via a universal joint 44, so that the hollow drum hammer 45 can fit the terrazzo, that is, it can measure the horizontal angle of the terrazzo surface.

[0054] In a specific embodiment, the adjustable base 12 includes a base plate 121, a second horizontal monitoring device 124 and a plurality of telescopic cylinders 122. For example, four telescopic cylinders 122 are provided between the top of the traveling trolley 10 and the base plate 121. The telescopic cylinders 122 are equipped with a cylinder controller 123. The telescopic cylinders have a telescopic adjustment function. The cylinder controller 123 can control the extension and contraction of the telescopic cylinders and has functions such as command execution and signal transmission. It can receive instructions sent by the main control module 50 and perform operations, and at the same time feedback the extension information to the main control module 50. The second horizontal monitoring device 124 has functions such as real-time monitoring of the tilt angle and data feedback, and feeds back the monitoring data to the main control module 50. The second horizontal monitoring device 124 is provided at the center of the adjustable base 12 and can be a gravity sensor or an inclinometer. The main control module 50 can collect the angle data of the second level monitoring device, determine whether the base plate 121 is level, and send instructions to the cylinder controller 123 so that the cylinder controller 123 controls the telescopic cylinder 122 to make the base plate 121 in a horizontal state.

[0055] In a specific embodiment, the detection system 40 also includes a displacement monitoring device, which is used to measure the vertical displacement data of the connecting rod 43; the main control module 50 can collect the displacement data of the displacement monitoring device and determine whether there is a height difference between the terrazzo on both sides of the walking vehicle 10. The principle is: the adjustable base 12 is in a horizontal state, the connecting rod 43 is at the same height, and the hollow drum hammer 45 is at the same height. When the hollow drum hammer 45 moves downward and contacts the terrazzo, the displacement data recorded by the displacement monitoring devices on both sides should be the same. If they are different, there is a height difference between the two sides, and the height of the terrazzo block on the side with the smaller value is higher than the height of the terrazzo block on the side with the smaller value. The displacement monitoring device can use a distance measuring instrument. In this embodiment, the displacement monitoring device includes a pull rope 49 and a pull-wire displacement meter 48. The pull-wire displacement meter 48 is set on the adjustable base 12. The bottom of the pull rope 49 is connected to the pull-wire displacement meter 48, and the top is vertically connected to the horizontal part of the connecting rod 43.

[0056] In a specific embodiment, the driving mechanism includes a motor 41 and a suspension rope 42 wound around the rotating wheel of the motor 41, and the bottom of the suspension rope 42 is fixedly connected to the horizontal portion of the connecting rod 43. The motor 41 has a rotation function, which is used for winding and retracting the suspension rope 42 up and down, and has functions such as command execution and signal transmission. It can receive the instructions sent by the main control module 50 and perform operations, and feed back rotation information to the main control module 50. As an example, when the motor 41 rotates forward, the pull rope 49 is unfolded downward under the gravity of the hollow drum percussion hammer 45, so that the hollow drum percussion hammer 45 can percussion the terrazzo. When the motor 41 is reversed, the pull rope 49 is wound around the rotating wheel of the motor 41, so that the hollow drum percussion hammer 45 rises.

[0057] In a specific embodiment, combining Figure 1 and Figure 2 As shown, the terrazzo floor 1 to be inspected in a room includes 36 terrazzo pieces in 6 rows and 6 columns. The virtual inspection space 31 is also divided into 36 virtual terrazzo pieces 32, which are assumed to be numbered #1-1 to #1-6, #2-1 to #2-6, #3-1 to #3-6, #4-1 to #4-6, #5-1 to #5-6, and #6-1 to #6-6. Figure 2The walking path of the trolley is to walk longitudinally along the adjacent axes between #1-1 and #2-1 (numbered from low to high). During the movement, the positioning device 20 performs position positioning in real time. After each group of terrazzo (two terrazzos on the left and right sides of the adjacent axes are a group) detection blocks are moved, the back-end system 30 feedbacks the information that the trolley has arrived at the corresponding detection block to the main control module 50. After receiving the information, the main control module 50 sends an in-place stop instruction to the trolley control module 11. After receiving the instruction, the trolley control module 11 controls the walking trolley 10 to perform a stop operation. After the detection system 40 completes the corresponding detection, the main control module 50 issues an instruction to the trolley control module 11 to move to the next group of terrazzo detection blocks. The trolley control module 11 controls the walking trolley 10 to perform the corresponding operation. And so on, until it reaches the edge detection position (#1-6 / #2-6 center axis) and the detection system 40 completes the detection, the back-end system 30 feeds back the trolley arrival information to the main control module 50, and the main control module 50 sends the in-place lateral walking instruction to the trolley control module 11 after receiving the information, and the trolley control module 11 controls the walking trolley 10 to perform the lateral walking operation after receiving the instruction, until it reaches the adjacent axis between #2-6 / #3-6, and the back-end system 30 feeds back the walking trolley arrival information to the main control module 50, and the main control module 50 sends the in-place stop instruction to the trolley control module 11 after receiving the instruction, and the trolley control module 11 controls the walking trolley 10 to perform the stop operation, and enters the next group of detection areas after the detection system 40 completes the corresponding detection, and so on. The trolley 10's travel path 33 follows the adjacent axes #2-6 and #3-6 (numbered from highest to lowest) until it reaches the outermost detection position (the center axis of #2-1 / #3-1), whereupon it moves horizontally to the next row of detection blocks. This process repeats back and forth until all terrazzo detection blocks have been exhausted. During this process, the positioning device 20 acquires the trolley's 10 position in real time and associates it with the corresponding position in the virtual detection space 31. When the overall direction of the walking trolley 10 remains unchanged, the longitudinal and lateral sliding movement of the walking trolley 10 can be achieved by converting the longitudinal and lateral rollers. The hollow drum striking hammers 45 (assuming they are a and b) on the left and right sides of the walking trolley 10 always correspond to striking the adjacent terrazzo blocks on both sides. For example, #2-1 corresponds to a, #1-1 corresponds to b; #3-6 corresponds to a, #2-6 corresponds to b. At the same time, the components on the left side of the mounting plate 13 are numbered as group a, and the components on the right side are numbered as group b. For example, the hollow drum striking hammer 45 on the left side of the mounting plate 13 is numbered as hollow-a, and the sound monitoring module 46 is numbered as sound-a.During the inspection, the adjustable base 12 is in a horizontal state, the hollow drum striking hammers 45 on both sides of the walking trolley 10 are at the same height, and the driving mechanism drives the connecting rod 43 to move slowly downward along the sliding track 14 until the bottom hollow drum striking hammer 45 touches the terrazzo surface and makes a corresponding sound; after the sound monitoring module 46 at the bottom of the walking trolley 10 receives the corresponding sound data, it feeds back to the main control module 50, and the main control module 50 performs large model data analysis and identification based on the collected sound data to determine whether the terrazzo on this side is in a hollow state; if it is hollow, the main control module 50 issues a marking command to the back-end system 30, and the back-end system 30 automatically locates and identifies after receiving the command, and marks the virtual terrazzo block 32 with the corresponding number in the virtual detection space 31 as abnormal, and indicates that the abnormal type is "hollow", otherwise it is normal and enters the next detection item. After the hollowing status of the terrazzo blocks on both sides is detected, the first horizontal monitoring device 47 on the hollowing hammers 45 on both sides collects the horizontal status of the corresponding hollowing hammers 45 and feeds the data back to the main control module 50; if the tilt value is not "0", it means that the hollowing hammer 45 on the current side is in a tilted state and the terrazzo block on the corresponding side is tilted. The main control module 50 then issues a marking command to the back-end system 30. After receiving the command, the back-end system 30 automatically locates and identifies the virtual terrazzo block 32 with the corresponding number in the virtual detection space 31, and marks the abnormality as "tilted". If the tilt value on both sides is "0", the next detection item is entered. The displacement monitoring devices on both sides measure the distance traveled by the connecting rod 43 and feed this information back to the main control module 50. Upon receiving this displacement data, the main control module 50 determines whether the values on both sides are consistent. If the heights are unequal, indicating a height difference between the two terrazzo blocks, it issues a marking command to the back-end system 30. Upon receiving this command, the back-end system 30 automatically locates and identifies the terrazzo block 32 with the corresponding number within the virtual inspection space 31, marking it as abnormal and indicating the abnormality type as "height difference." Once all terrazzo blocks have been inspected, a diagram of the marked terrazzo block layout in the virtual inspection space 31 is sent to management personnel, allowing them to quickly identify abnormal terrazzo blocks and conduct rework and repair management.

[0058] Example 2

[0059] This embodiment provides a method for automatically detecting the quality of terrazzo construction using the aforementioned automatic detection device for terrazzo construction quality, comprising the following steps:

[0060] Step 1: Set up an automated terrazzo construction quality inspection device. Set up a virtual inspection space 31 corresponding to the terrazzo floor 1 to be inspected in the back-end system 30. Set up a terrazzo layout diagram and a travel path for the walking cart 10 in the virtual inspection space 31. The layout diagram includes m rows and n columns of terrazzo, and the travel path is set along the middle boundary between two columns of terrazzo. Simulate the position of the walking cart 10 in the virtual inspection space 31 based on the coordinate information fed back by the positioning device 20.

[0061] Step 2: The main control module 50 sends a command to the trolley control module 11 based on the terrazzo arrangement diagram in the backend system 30, the travel path of the trolley 10, and the position of the trolley 10, so that the trolley 10 moves to the boundary of the first group of terrazzo;

[0062] Step 3: The main control module 50 sends a command to the driving mechanism, causing the driving mechanism to drive the connecting rod 43 to move downward along the sliding track 14, so that the hollow drum hammer 45 strikes the terrazzo; the sound monitoring module 46 monitors the sound data of the hollow drum hammer 45 striking the terrazzo and transmits it to the main control module 50;

[0063] Step 4: The main control module 50 determines whether the terrazzo is hollow based on the sound data sent by the sound monitoring module 46, and marks the corresponding terrazzo as hollow if it is hollow; the main control module 50 sends an instruction to the driving mechanism, causing the driving mechanism to drive the connecting rod 43 to move upward along the sliding track 14, so that the hollow hammer 45 is away from the terrazzo for a distance;

[0064] Step 5: The main control module 50 sends a command to the trolley control module 11 to make the trolley 10 move to the boundary of the next group of terrazzo and repeat steps 3 and 4;

[0065] Step 6.
