Technical Field

[0001] This invention relates to the field of simulation testing technology, and in particular to a database-based device and method for simulating and analyzing mechanical injury accidents. Background Technology

[0002] Construction sites and workshops often require various types of machinery and equipment, which can pose a risk of injury to operators, presenting multiple potential hazards. Existing technologies primarily use fixed and predictable simulation devices, making it difficult to simulate real-life hazards. Furthermore, simulations require manual operation, which is extremely dangerous without proper protection.

[0003] Therefore, there is an urgent need for a mechanical injury accident simulation and analysis device that can be both variable and fixed. Summary of the Invention

A drive wheel is fixedly mounted on the output end of the motor. The drive wheel is rotatably mounted on the protective shell. One end of the conveyor belt is sleeved on the drive wheel, and the other end of the conveyor belt is sleeved on the driven wheel.

[0008] In the first technical solution, the upper part of the limiting post is cylindrical, the middle part is semi-circular, and the lower part is thin cylindrical.

[0009] In the first technical solution, the shape of the limiting hole is half similar to the middle part of the limiting post, and a protrusion is provided on the lower side to limit the lower part of the limiting post. The other end of the limiting hole is semi-circular to limit the movement of the lower part of the post.

[0010] In the first technical solution, the support mechanism further includes a support wall one, on which three sliding platforms are slidably installed. A movable platform is fixedly installed on each sliding platform, and a gear assembly, a pulley assembly, and a cam assembly are fixedly installed on each movable platform.

A camera and a support wall two are also fixedly installed on the support wall one.

[0011] In the second technical solution, a database-based mechanical injury accident simulation and analysis method is provided, using a database-based mechanical injury accident simulation and analysis device as described in any one of the first technical solutions.

A drive assembly is mounted on the third motor 415. The drive assembly cooperates with the support mechanism 3 to control the movement of the support mechanism 3. The rotation of the second motor 401 drives the drive disk 402 to rotate, which in turn drives the moving rod 403 to move. The movement of the moving rod 403 drives the telescopic rod 404 to move, and the movement of the telescopic rod 404 drives the connecting rod assembly to move.

[0049] like Figure 10 , Figure 11 , Figure 12 As shown, a protrusion 420 is provided on the drive disk 402, and the moving rod 403 cooperates with the drive disk 402.

[0050] like Figure 10 , Figure 11As shown, the drive assembly includes: a drive worm gear 413, one end of which is fixedly mounted on a motor 415, the other end of which is rotatably connected to a limiting rod 414; driven worm gears 412 meshing on both sides of the drive worm gear 413; a worm shaft 419 fixedly mounted on the driven worm gear 412; the worm shaft 419 rotatably mounted on a support wall 308; a connecting plate 411 fixedly mounted on the worm shaft 419; a sliding plate 410 slidably mounted on the connecting plate 411; one end of a plurality of springs 418 fixedly mounted on the bottom of the sliding plate 410; the other end of the springs 418 fixedly connected to the connecting plate 411; and one end of a connecting post 409 fixedly mounted on the top of the sliding plate 410; the other end of the connecting post 409... A limiting rod 414 is fixedly connected to a sliding table 306 and fixedly installed on a support wall 308. A rack 416 is slidably mounted on the limiting rod 414. One end of a connecting short plate 417 is fixedly mounted on the rack 416, and the other end of the connecting short plate 417 is fixedly connected to the sliding table 306. The rack 416 meshes with a drive worm gear 413. The rotation of the motor 3 415 drives the drive worm gear 413 to rotate. The rotation of the drive worm gear 413 drives the driven turbines 412 on both sides to rotate. The rotation of the driven turbines 412 drives the connecting long plate 411 to move. The movement of the connecting long plate 411 drives the sliding plate 410 to move and contract or extend. The contraction or extension of the sliding plate 410 drives the spring 418 to contract or extend. The movement of the sliding plate 410 drives the connecting column 409 to move. The rotation of the drive worm gear 413 drives the rack 416 to move. The movement of the rack 416 moves the connecting short plate 417.

[0051] like Figure 13 As shown, the linkage assembly includes a second hinge platform 408, which is fixedly mounted on a movable platform 305. One end of a second hinge rod 407 is hinged to the second hinge platform 408, and one end of a first hinge rod 406 is hinged to the other end of the second hinge rod 407. The other end of the first hinge rod 406 is hinged to the first hinge platform 405. The first hinge platform 405 near the limiting rod 414 is slidably connected to the limiting rod 414. The remaining first hinge platforms 405 are slidably mounted on the second support wall 308. The other end of a telescopic rod 404 is sleeved at the hinge point between the first hinge rod 406 and the second hinge platform 408. The movement of the telescopic rod 404 causes the first hinge rod 406 and the second hinge platform 408 to move, which in turn causes the second hinge platform 408 to move, and the movement of the second hinge platform 408 causes the movable platform 305 to move.

[0052] like Figure 1 , Figure 2 , Figure 4 , Figure 5As shown, the transport mechanism 2 includes a motor 203, which is fixedly mounted on a support wall 307. A drive wheel 202 is fixedly mounted on the output end of the motor 203. The drive wheel 202 is rotatably mounted on a protective housing 201. One end of a conveyor belt 204 is fitted onto the drive wheel 202, and the other end of the conveyor belt 204 is fitted onto a driven wheel 207. The two ends of the driven wheel 207 are rotatably connected to the protective housing 201 and the support mechanism 3, respectively. The conveyor belt 204 is provided with multiple limiting holes 210, and cleaning components are installed on the limiting holes 210. The rotation of the motor 203 drives the drive wheel 202 to rotate, which in turn drives the conveyor belt 204 to rotate, and the rotation of the conveyor belt 204 drives the driven wheel 207 to rotate.

[0053] like Figure 1 , Figure 2 , Figure 3 , Figure 5 As shown, the cleaning component package includes a friction plate 206. Both ends of the friction plate 206 are slidably connected to the protective shell 201 and the support wall 307, respectively. Multiple limiting posts 208 are installed on the friction plate 206, and each limiting post 208 is fixedly installed on the connecting plate 205. Multiple soft bristles 209 are fixedly installed on the connecting plate 205.

[0054] like Figure 3 As shown, the upper part of the limiting column 208 is cylindrical, the middle part is semi-circular, and the lower part is thin cylindrical.

[0055] like Figure 3 , Figure 4 As shown, the shape of the limiting hole 210 is similar to the middle part of the limiting post 208, and a protrusion is provided on the lower side to limit the lower part of the limiting post 208. The other end of the limiting hole 210 is semi-circular to limit the movement of the lower part of the post 208.

[0056] like Figure 2 , Figure 4 As shown, a gap is provided between the conveyor belt 204 and the supporting wall 307 to facilitate the falling of damaged objects.

[0057] like Figure 1 , Figure 6 As shown, the support mechanism 3 includes a support wall 307, on which three sliding platforms 306 are slidably installed. Each sliding platform 306 is fixedly installed with a moving platform 305. Each moving platform 305 is fixedly installed with a gear assembly, a pulley assembly, and a cam assembly. The moving platform 305 is fixedly connected to the other end of the adjacent connecting column 409 or connecting short plate 417. A camera 301 and a support wall 308 are also fixedly installed on the support wall 307.

[0058] like Figure 7 , Figure 8, Figure 9 As shown, the gear assembly, pulley assembly, and cam assembly can all be disassembled and replaced with other mechanical components, and each has an independent power source, such as being replaced with sprockets, worm gears, and bevel gears.

[0059] like Figure 7 As shown, the gear assembly includes a driving gear 303 that meshes with a driven gear 309, and both the driving gear 303 and the driven gear 309 are rotatably mounted on a movable stage 305.

[0060] like Figure 9 As shown, the pulley assembly includes a small pulley 310, on which one end of a plurality of belts 311 are fitted. The other end of the belts 311 is fitted on a large pulley 302. The small pulley 310 and the large pulley 302 are both rotatably mounted on a movable table 305.

[0061] like Figure 8 As shown, the cam assembly includes a cam 304, which is rotatably mounted on a movable stage 305.

[0062] like Figure 1 As shown, multiple character models 1 can be set, such as standing, moving, working, male, female, etc. Character models 1 are fixedly installed on conveyor belt 204 and can be detached.

[0063] like Figure 6 As shown, camera 301 corresponds to a camera device in a database-based mechanical injury accident simulation analysis method. The captured content is analyzed and processed using a database-based mechanical injury accident simulation analysis method.

[0064] Working principle: In the following content, gear assembly, pulley assembly and cam assembly are collectively referred to as mechanical components.

[0065] Option 1: Place the mannequin model 1 to be tested on the conveyor belt 204, then start the power source of the mechanical components to make them work. Select the initial positions of the three sliding platforms 306 according to the practical situation, then start motor 1 203. Motor 1 203 rotates, driving the drive wheel 202, which in turn rotates the conveyor belt 204, which in turn rotates the driven wheel 207, causing the mannequin model 1 to move. When the mannequin model 1 moves to the mechanical components to be tested, start motor 2 401. Motor 2 401 rotates, driving the drive disc 402, which in turn moves the moving rod 403, which in turn moves the telescopic rod 404, which in turn moves the hinge rod 1 406 and the hinge platform 2 408, which in turn moves the hinge platform 2 408. The movement of the articulated platform 408 drives the movement of the moving platform 305. The movement of the moving platform 305 moves the mechanical components on the moving platform 305 to contact or reach the limit distance of the human model 1. The camera 301 detects and records this, obtaining mechanical operation data. Based on the above method, the mechanical operation data is used to predict whether a mechanical injury accident will occur at the mechanical operation point. If a mechanical injury accident is determined to occur, point cloud information is generated based on the mechanical operation data. The point cloud information and mechanical operation data can also be retrieved from the database. The point cloud information and mechanical operation data are optimized. Based on the point cloud information, a simulated accident injury animation is generated. The mechanical operation data and point cloud information are stored in the database.

[0066] Option 2: Place the required experimental figure model 1 on the conveyor belt 204, then start the power source of the mechanical components to make the gear mechanical components work. Then, select the initial positions of the three sliding tables 306 according to the practical situation, and then start the motor 3 415. The rotation of the motor 3 415 drives the drive worm 413 to rotate. The rotation of the drive worm 413 drives the driven worms 412 on both sides to rotate. The rotation of the driven worms 412 drives the connecting plate 411 to move. The movement of the connecting plate 411 drives the sliding plate 410 to move and retract or extend. The retraction or extension of the sliding plate 410 drives the spring 418 to retract or extend. The movement of the sliding plate 410 drives the connecting column 409 to move. The movement of the connecting column 409 drives the sliding table 306 on the connecting column 409 to move. The movement of the sliding table 306 drives the sliding table 306 to move. The movable stage 305 moves, causing the mechanical components on the movable stage 305 to move, driving the worm gear 413 to rotate and causing the rack 416 to move. The rack 416 moves, causing the connecting short plate 417 to move. The connecting short plate 417 moves, causing the sliding stage 306 on the connecting short plate 417 to move. The sliding stage 306 moves, causing the movable stage 305 on the sliding stage 306 to move. The movable stage 305 moves, causing the mechanical components and the second hinge stage 408 on the movable stage 305 to move. The second hinge stage 408 moves, causing the second hinge rod 407 to move. The second hinge rod 407 moves, causing the first hinge rod 406 to move. The first hinge rod 406 moves, connecting to the first hinge stage 405. The movement of hinge rod 406 and hinge rod 407 causes the telescopic rod 404 to retract or extend. Simultaneously, motor 401 is activated, rotating the drive disc 402, which in turn moves the moving rod 403. This movement then moves the telescopic rod 404, which in turn moves hinge rod 406 and hinge platform 408. This movement then moves hinge platform 408, which in turn moves the moving platform 305. Finally, motor 203 is activated, rotating the drive wheel 202, which in turn rotates the conveyor belt 204. The conveyor belt 204 then rotates the driven wheel 207. The rotation causes the character model 1 to move, and the movement of the moving platform 305 causes the mechanical components on the moving platform 305 to move to contact with or to the limit distance of the character model 1, making the position and time of the mechanical components appear random. The camera 301 detects and records the data, obtaining the mechanical operation data. Based on the above method, the mechanical operation data is used to predict whether a mechanical injury accident will occur at the mechanical operation point. If a mechanical injury accident is determined to occur, point cloud information is generated based on the mechanical operation data. The point cloud information and mechanical operation data can also be retrieved from the database. The point cloud information and mechanical operation data are optimized. Based on the point cloud information, a simulated accident injury animation is generated. The mechanical operation data and point cloud information are stored in the database.

[0067] Cleaning: When motor 203 starts, its rotation drives the drive wheel 202 to rotate, which in turn drives the conveyor belt 204 to rotate. The conveyor belt 204 then drives the driven wheel 207 to rotate, which in turn moves the limiting post 208. The movement of the limiting post 208 then moves the friction plate 206. During the return stroke, the friction plate 206 overcomes friction and moves the limiting post 208. Since there is no obstruction on the moving side of the limiting post 208, it tilts. This tilting causes the connecting plate 205 to tilt, which in turn moves the transport mechanism 290, preventing the soft bristles 209 from contacting the protective shell 201. During forward movement, the friction plate 206 overcomes friction and moves the limiting post 208. Because the limiting post 208 is restricted by the protrusion on the limiting hole 210 on the moving side, it remains stationary, allowing the soft bristles 209 to contact the protective shell 201 and perform cleaning during the movement.

[0068] Example 2

[0069] Based on the database-based mechanical injury accident simulation and analysis device in Embodiment 1, this embodiment proposes a database-based mechanical injury accident simulation and analysis method. The "machinery" in this embodiment refers to the database-based mechanical injury accident simulation and analysis device in Embodiment 1.

[0070] like Figure 14 As shown, a database-based method for simulating and analyzing mechanical injury accidents is described, wherein the support mechanism 3 is equipped with a camera device and a processing system.

[0071] S101: Obtain monitoring video of the monitoring site; the monitoring video is captured by a camera device.

[0072] S102: Obtain data on the operation of machinery based on monitoring video.

[0073] S103: Predict whether mechanical injury accidents will occur at mechanical operation points based on mechanical operation data.

[0074] S104: If a mechanical injury accident is determined to have occurred, point cloud information is generated based on the mechanical operation data.

[0075] S105: Generate simulated accident injury animation based on point cloud information; store mechanical operation data and point cloud information in the database.

[0076] Retrieve point cloud information and machine operation data from the database. Optimize the point cloud information and machine operation data. Specifically, this includes repairing, adding, deleting, and modifying the point cloud data.

[0077] Optionally, based on the monitoring video, data on the mechanical operation status can be obtained, including:

[0078] The operation trajectory information of the mechanical operation points in the monitoring video is extracted based on the target tracking algorithm, and the operation trajectory information is used as mechanical operation data. In this embodiment of the invention, the target tracking algorithm may employ background subtraction, frame difference, optical flow, Gaussian mixture model, or convolutional neural network (CNN).

[0079] Among them, the operation trajectory information represents the motion trajectory of the machine.

[0080] Optionally, predicting whether a mechanical injury accident will occur at a mechanical operation point based on the aforementioned mechanical operation data includes:

[0081] Retrieve pre-stored mechanical standard operation motion information from the database. This information represents the mechanical trajectory under standard operation and normal mechanical conditions.

[0082] The standard deviation between the operation trajectory information and the standard mechanical operation motion information is obtained. If the standard deviation is greater than a set value, it is determined that a mechanical injury accident will occur at the mechanical operation point. In this embodiment of the invention, the set value can be 0.1, 0.2, or 0.5.

[0083] Optionally, the standard deviation between the operation trajectory information and the standard mechanical operation motion information is obtained, including: the operation trajectory information includes multiple mechanical operation position information; the standard mechanical operation motion information includes multiple standard operation position information; and the standard deviation between the multiple mechanical operation position information and the multiple standard operation position information is used as the standard deviation between the operation trajectory information and the standard mechanical operation motion information.

[0084] By adopting the above scheme, data on mechanical operation obtained from monitoring images can be conveniently and promptly grasped, improving the accuracy of the obtained data. Based on this data, the likelihood of mechanical injury accidents at operation points can be predicted, offering convenience, speed, timeliness, and high accuracy, providing crucial information for further safety precautions. If a mechanical injury accident is confirmed, point cloud information is generated based on the mechanical operation data; based on this point cloud information, a simulated accident injury animation is generated. This achieves high accuracy and safety in generating simulated accident animations based on actual mechanical operation conditions.

[0085] Example 3

[0086] This invention also provides an electronic device, such as...
