In industrial production, improving production efficiency and creating intelligent and unmanned production lines have become the current development trend. At the same time, creating intelligent production lines requires a large number of highly reliable sensors to cooperate;

[0003] The lidar can perform 2D 360-degree scanning, realizing functions such as static target detection within a space, point cloud data output, high-precision three-dimensional imaging, target recognition, spatial scanning imaging, volume and weight calculation output, etc. It can be applied in scenarios such as intelligent transportation, warehousing and logistics, and working condition monitoring for volume detection, weight assessment, contour scanning, etc., to achieve industrial intelligence and digitization, providing technical support for subsequent creation of intelligent production. The method of scanning goods by the lidar is also called inventory.

[0004] However, when installing the scanning lidar used for material inventory, multiple clamps are required for fixation, the operation is relatively inconvenient, and it is not convenient to disassemble after the clamps are installed; therefore, it does not meet the existing requirements.

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0021] As Figures 1 to 4 shown, an intelligent inventory device using lidar three-dimensional imaging, a plurality of scanning lidars 2 are arranged at equal intervals below the support crossbeam 1, a support plate 4 is fixed on the upper surface of the scanning lidar 2, the support plate 4 fits the bottom surface of the support crossbeam 1, a reinforcement block 7 is installed above the support plate 4, connecting straps 5 are fixed on both sides of the support plate 4, docking buckles 10 are fixed at the top ends of the connecting straps 5, docking grooves 9 are provided on both sides of the reinforcement block 7, and the docking buckles 10 are inserted into the inner sides of the docking grooves 9. A buffer rod 3 is slidably installed at the bottom of the reinforcement block 7, and a pressure plate 6 is fixed at the bottom end of the buffer rod 3. The support plate 4 is fitted to the bottom surface of the support crossbeam 1, the pressure plate 6 is fitted to the top surface of the support crossbeam 1, and then the docking buckle 10 at the top end of the connecting strap 5 is inserted into the docking groove 9 on the side of the reinforcement block 7. The support plate 4 and the reinforcement block 7 are connected and fixed by the connecting strap 5 and the docking buckle 10, so as to realize the installation of the scanning lidar 2. After installation, the scanning lidar 2 can be disassembled by simply pulling out the docking buckle 10 from the docking groove 9. The operation is simple, fast, the installation difficulty is low, and it is convenient to replace the scanning lidar 2.

[0022] An annular protrusion is provided on the outer side of the top end of the buffer rod 3 and is slidably inserted into the support crossbeam 1. A reinforcement spring 8 is fixed between the top end of the buffer rod 3 and the reinforcement block 7. The buffer rod 3 and the reinforcement block 7 are elastically supported by the reinforcement spring 8, so that the pressure plate 6 is pressed tightly against the top of the support crossbeam 1 by the elastic force of the reinforcement spring 8, and the reinforcement block 7 is pushed upward, so that the connecting strap 5 generates a pulling force on the support plate 4, so that the support plate 4 is closely attached to the bottom of the support crossbeam 1, fixing the scanning lidar 2 to prevent the scanning lidar 2 from shifting or vibrating.

[0023] The inner side of the docking buckle 10 is provided with a U-shaped groove. The docking buckle 10 is made of plastic material. When the docking buckle 10 with a U-shaped groove on the inner side is simultaneously squeezed from the upper and lower sides, it can bend and deform towards the middle, ensuring that the docking buckle 10 can smoothly enter and exit the docking groove 9, realizing the connection or separation of the connecting strap 5 and the reinforcement block 7.

[0024] Both the upper and lower surfaces of the docking buckle 10 are provided with arc-shaped grooves. The inner wall of the docking groove 9 is provided with two anti-slip arc-shaped strips 11 that are symmetric up and down. The anti-slip arc-shaped strips 11 are clamped in the arc-shaped grooves, increasing the frictional resistance between the docking buckle 10 and the docking groove 9, ensuring that the docking buckle 10 cannot be separated from the docking groove 9 without human intervention, and ensuring the stability after the connection of the connecting strap 5 and the reinforcement block 7.

[0025] Both sides of the support plate 4 slope upward at an angle of 45 degrees. The surface of the support plate 4 is provided with a circular arc-shaped groove. The support plate 4 is made of rubber material, and the center of the groove is the same as the center of the support cross beam 1. When the rubber support plate 4 is subjected to an upward pulling force from the connecting strap 5 on the side, the side of the support plate 4 bends upward and fits the outer surface of the support cross beam 1, increasing the frictional resistance between the support plate 4 and the support cross beam 1, ensuring that the support plate 4 will not slide or deflect at the bottom of the support cross beam 1, and ensuring the stability after the installation of the scanning lidar 2.

[0026] In this embodiment, the antenna beam angle of the scanning lidar 2 is extremely narrow. Through 360-degree rotation in two-dimensional axial directions, the final 3D scanning imaging effect is achieved. Users can perform inventory checking, target recognition, and volume measurement according to the effect presented by the scanning lidar 2.

[0027] The scanning lidar 2 is installed on the top of the warehouse and hoisted above the material level; if the on-site warehouse is large, multiple radars can also be installed, and the final data is summarized to the platform for integration and splicing work.

[0028] The best installation position of the scanning lidar 2 is directly above the material pile. The installation height of the radar is related to the effective scanning area. If the area of the material pile exceeds the effective scanning area of the radar, two or more radars need to be installed for splicing to achieve a full-coverage effect.

[0029] If the large area of the measured material pile is a plane, it is advisable that the effective incident angle of the radar irradiating the material pile < 60 degrees. The corresponding table of the radar installation height and the effective detection range is as follows.

[0030] The corresponding table of the radar installation height and the effective detection area is as follows:

[0031] Radar installation height Effective detection range (radius) 10m 17m 12m 20m 14m 24m 16m 27m 18m 31m 20m 34m 25m 43m 30m 50m

[0032] If the measured target is an irregular stockpile and there are multiple peaks and valleys blocking the radar beams from each other, multiple radars need to scan from different perspectives and finally be stitched together to achieve the effect of accurate imaging. The specific number of radars used needs to be determined according to the actual situation on site. It is advisable to install the radar directly above the stockpile without the blind area of the radar view blocked by the stockpile.

[0033] Working principle: When installing the scanning lidar 2, first connect the connecting strap 5 on one side of the support plate 4 to the reinforcement block 7. Slide the docking buckle 10 at the end of this connecting strap 5 into the docking groove 9 on one side of the reinforcement block 7, so that the docking buckle 10 completely enters the interior of the docking groove 9. Then, fit the support plate 4 to the bottom of the support crossbeam 1, and fit the pressure plate 6 below the reinforcement block 7 to the top of the support crossbeam 1. Next, insert the docking buckle 10 at the top of another connecting strap 5 into the docking groove 9 on the other side of the reinforcement block 7 until the docking buckle 10 at the end of the connecting strap 5 completely enters the inner side of the docking groove 9, and the anti-slip arc strip 11 inside the docking buckle 10 is clamped in the arc grooves on the upper and lower surfaces of the docking buckle 10. At this time, release the reinforcement block 7, and the reinforcement spring 8 between the buffer rod 3 and the reinforcement block 7 elastically stretches. After stretching, the reinforcement spring 8 exerts a downward force on the buffer rod 3 and the pressure plate 6, so that the pressure plate 6 is tightly pressed against the top of the support crossbeam 1. At the same time, the reinforcement spring 8 pushes the reinforcement block 7 upward, so that the reinforcement block 7 generates an upward pulling force on the connecting strap 5, causing the connecting strap 5 to pull the side of the support plate 4 upward. The support plate 4 bends upward and fits the outer surface of the support crossbeam 1, realizing the rapid installation of the scanning lidar 2. Moreover, the operation is relatively simple and the operation difficulty is low. At the same time, by using the pulling force of the connecting strap 5 on the support plate 4 and the pressure of the reinforcement spring 8 on the pressure plate 6, the support plate 4 and the pressure plate 6 are tightly attached to the support crossbeam 1, ensuring that the scanning lidar 2 will not move or shift in position after installation.
