Description

Technical Field

[0001] This utility model relates to the field of vehicle accident detection technology, specifically a vehicle accident identification device based on motion detection. Background Technology

[0002] When two vehicles collide on the road, the process of getting out of the car, calling the police, and the traffic police determining liability, assessing damage, processing claims, and leaving the scene can cause traffic congestion. Installing cameras on the road allows for real-time monitoring of vehicle speed and position changes during accidents. Once a collision occurs and the vehicle's speed drops to zero, the "event" is reported to the management department, triggering a mechanism to upload video footage. Traffic police can then handle the situation online without going to the scene. The hardware consists of cameras that use motion detection technology to monitor vehicle speed and position changes in real time, accurately identifying single / multi-vehicle collisions, abnormal stationary situations, and other accident scenarios (including excluding license plate obstruction and congestion-related false alarms). A network of cameras with a range of 100 meters covers the entire road segment. It achieves second-level accident alerts (pushing license plate, location, and time), adapting to urban main roads, highways, and other scenarios. Compared to traditional systems, it offers improved detection accuracy (distinguishing between congestion and accidents), faster response speed (automatic triggering of warnings), and more flexible deployment (hybrid camera network), solving the problems of "difficult detection and high false alarm rates" of road accidents. It provides traffic management departments with real-time monitoring and rapid response capabilities, typically requiring cameras to be deployed across various road segments.

[0003] Typical cameras are installed at a high position, mounted on the upper part of the road via a fixed crossbar, to capture and detect road conditions. To ensure stability, these cameras are usually fixed directly to the surface of the crossbar with bolts, which makes them difficult to disassemble and reassemble quickly for maintenance, thus causing some inconvenience in actual use.

[0004] Therefore, we propose a vehicle accident identification device based on motion detection to address the aforementioned problems. Utility Model Content

[0005] The purpose of this utility model is to provide a vehicle accident recognition device based on motion detection, in order to solve the problem mentioned in the background art that the general camera is set at a high position and is set at the upper end of the road by a fixed crossbar for capturing and detecting road conditions. In order to ensure the stability of the installation, the camera is usually fixed directly to the surface of the crossbar with bolts, etc., which cannot be quickly disassembled and assembled when maintenance is needed, so there are certain inconveniences in actual use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a system for rapidly identifying vehicle accidents based on motion detection technology, comprising a fixed rod and a mounting block fixedly installed at the lower end of the fixed rod. Cameras are mounted at both ends of the mounting block, and baffles are fixedly installed on both sides of the mounting block. A sliding groove is formed on the mounting block, and connecting components are slidably installed on both sides of the sliding groove. Each connecting component includes a connecting block slidably installed within the sliding groove. A connecting plate is fixedly installed on one side of the connecting block. Mounting grooves are formed on both sides of the connecting block, and locking blocks are slidably installed within each mounting groove. A spring is fixedly installed between the side wall of the locking block and the inner wall of the mounting groove. Locking slots are formed on both side walls of the mounting block, and the locking blocks are slidably connected within the locking slots.

[0007] Preferably, connecting rods are fixedly installed on both sides of the connecting plate, and the camera is rotatably installed between the two connecting rods.

[0008] Preferably, both side walls of the mounting block are provided with release components, and the release components include a fixing frame fixedly installed on the outer side wall of the mounting block.

[0009] Preferably, the fixed frame has a movable groove, which is directly opposite the slot, and a slider is slidably installed in each movable groove.

[0010] Preferably, each slider is fixedly mounted with a limiting block, and a spring is fixedly mounted between the side wall of the limiting block and the inner wall of the movable groove.

[0011] Preferably, one end of the slider is slidably connected to the cab slider in the slot, which is in contact with the card block, and the inner side of the card block is an arc-shaped surface.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. When the device needs to be disassembled and repaired, the two side locking blocks can be pressed inward to push the inside of the connecting block, and the connecting block can be pulled outward to complete the overall disassembly of the connecting component and the camera. After the repair is completed, the connecting block is slid against the inner wall of the mounting block's groove. When the connecting block moves to the mounting slots on both sides and is aligned with the locking slots, the connecting component and the camera can be fixedly installed under the action of the spring. When the system based on motion detection technology for quickly identifying vehicle accidents needs to be repaired, the fixing limit of the connecting component and the camera can be released by pushing the locking blocks into the mounting slots, and the whole thing can be removed for easy repair. After the repair is completed, the whole thing can be pushed back to complete the fixation. The operation is simple and convenient.

[0014] 2. With the cooperation of the fixed frame, movable groove, slider, limit block and spring 2, the device can fix and limit the connecting component through the release component set on the side wall when disassembling. This can prevent external dust from entering the inside of the slot during daily use and affecting disassembly and assembly. The setting of the release component can prevent dust from entering the slot and make disassembly more convenient. When it is necessary to install the connecting component under the mounting block, the connecting block can be pushed along the slide groove to squeeze and slide the card block into the inside of the connecting block without manual pressing.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1: Please refer to Figures 1-3A system for rapidly identifying vehicle accidents based on motion detection technology includes a fixed rod 1 and a mounting block 2 fixedly installed at the lower end of the fixed rod 1. Cameras 3 are installed at both ends of the mounting block 2, and baffles 5 are fixedly installed on both sides of the mounting block 2. A sliding groove 21 is provided on the mounting block 2, and a connecting component 4 is slidably installed on both sides of the sliding groove 21. The connecting component 4 includes a connecting block 41 slidably installed in the sliding groove 21, a connecting plate 42 fixedly installed on one side of the connecting block 41, and mounting grooves 43 are provided on both sides of the connecting block 41. A locking block 44 is slidably installed in each mounting groove 43. A spring 45 is fixedly installed between the side wall of the locking block 44 and the inner wall of the mounting groove 43. A locking groove 22 is provided on both side walls of the mounting block 2, and the locking block 44 is slidably connected in the locking groove 22.

[0022] In this embodiment: when the device needs to be disassembled and repaired, the two locking blocks 44 on both sides can be pressed inward. When the locking blocks 44 are pressed, they slide along the locking groove 22 into the mounting groove 43. At this time, the locking blocks 44 slide to the connecting block 41. Inside the mounting block 2, the connecting block 41 can be pulled outward. When the connecting block 41 is pulled outward, the locking block 44 is pressed against the inner wall of the slide groove 21 by the spring 45. When the connecting block 41 is pulled out of the slide groove 21, the overall disassembly of the connecting component 4 and the camera 3 is completed. After the maintenance is completed, the connecting block 41 can be slid against the inner wall of the slide groove 21 of the mounting block 2. When sliding, the locking blocks 44 on both sides are pressed into the mounting groove 43 again. When the connecting block 41 moves to the mounting groove 43 on both sides and the locking groove 22, the connecting component 4 and the camera 3 can be fixedly installed under the action of the spring 45. When the system based on motion detection technology for quickly identifying vehicle accidents needs maintenance, the fixing limit of the connecting component 4 and the camera 3 can be released by pushing the locking block 44 into the mounting groove 43, and the whole can be removed for maintenance. After the maintenance is completed, the whole can be pushed back to complete the fixation. The operation is simple and convenient.

[0023] Example 2: This example is an improvement on Example 1. For details, please refer to [link / reference]. Figures 2-4 Connecting rods 46 are fixedly installed on both sides of the connecting plate 42. The camera 3 is rotatably installed between the two connecting rods 46, and the angle of the camera 3 can be adjusted by the connecting rods 46.

[0024] Both sides of the mounting block 2 are provided with release components 6, and the release components 6 include a fixing frame 61 that is fixedly installed on the outer side wall of the mounting block 2.

[0025] The fixed frame 61 has a movable groove 62, which is directly opposite the slot 22. A slider 63 is slidably installed in each movable groove 22.

[0026] Limiting blocks 64 are fixedly installed on each slider 63, and springs 65 are fixedly installed between the side wall of the limiting block 64 and the inner wall of the movable groove 62.

[0027] One end of the slider 63 is slidably connected in the slot 22. The slider 63 in the cab contacts the block 44, and the inner side of the block 44 is an arc-shaped surface.

[0028] In this embodiment: when the device needs to be inspected and disassembled, the sliders 63 on both sides can be pushed inward. When the sliders 63 slide into the movable groove 62, they can drive the limiting block 64 to move along its inner wall. During the movement, the sliders 63 press against the spring 65. The sliders 63 move to contact the internal locking block 44. Continuing to push will push the locking block 44 into the interior of the connecting block 41. At this time, the connecting block 41 can be pulled out along the slide groove 21 to remove the connecting component 4 and the camera 3 for inspection. After the inspection is completed, the connecting block 41 is pushed back along the slide groove 21 to the lower end of the mounting block 2. When pushing, the two sides of the locking block 44 are pressed by the slide groove 21 and can automatically slide. Move the connecting block 41 into the mounting slot 43 and continue pushing the connecting block 41 into the slot 22 on both sides to complete the fixing and limiting of the connecting component 4 and the camera 3. When disassembling the device, the connecting component 4 can be fixed and limited by the release component 6 set on the side wall. This can prevent external dust from entering the slot 22 during daily use and affecting disassembly and assembly. The release component 6 sets up a dustproof function for the slot 22 and makes disassembly more convenient. When it is necessary to install the connecting component 4 under the mounting block 2, simply push the connecting block 41 along the slide 21 and the slot 44 will be squeezed and slid into the interior of the connecting block 41 through the slide 21 without manual pressing.

[0029] The vehicle accident recognition device based on motion detection described in this utility model can realize real-time monitoring of vehicle speed and position changes, and accurately identify accident scenarios such as multi-vehicle / single-vehicle collisions and abnormal stationary conditions (including license plate obstruction and misjudgment of congestion). Through a network of cameras with a range of 100 meters to cover the entire road section, it can achieve second-level accident alarm (pushing license plate, location, and time).

[0030] In addition, this device can be adapted to urban main roads, highways and other scenarios. Compared with traditional recognition device systems, this device has higher detection accuracy (able to distinguish between congestion and accidents), faster response speed (automatically triggers alarms), and more flexible deployment (hybrid camera networking). It can effectively solve the problems of "difficulty in detecting and high false alarm rate" of road accidents, and provide traffic management departments with timely monitoring and rapid response capabilities.

[0031] This device can accurately capture accident characteristics such as stationary vehicles (speed of 0) and abnormal collisions on the road through motion detection technology (such as real-time monitoring of vehicle speed and position changes), and quickly identify accident scenarios, including but not limited to complex situations such as single / multi-vehicle collisions, license plate obstruction, and elimination of congestion misjudgments.
