Description

Technical Field

[0001] This invention belongs to the field of access control gates, and particularly relates to a collision-resistant, high-stability gate with a lifting arm. Background Technology

[0002] As a key piece of equipment for managing vehicle passage, barrier gates are widely used in parking lots, toll stations, and residential community entrances. Their basic function is to use a motor to drive the gate arm to raise and lower, thereby allowing or blocking vehicles. In this process, the smoothness and accuracy of the gate arm's operation, as well as the long-term reliability of the entire system, are the core indicators for evaluating the quality of a barrier gate.

[0003] To achieve high stability, existing technologies primarily optimize both the mechanical structure and control logic. In terms of mechanical structure, common methods include enhancing the overall rigidity of the chassis, using high-strength aluminum alloy gate arms, equipping them with precision geared motors, and optimizing lever balance design. These measures aim to ensure smooth operation of the gate arm during frequent starts and stops, resisting wind loads and reducing vibration. In terms of control logic, improvements are often made to the motor's start-stop curves and the addition of soft-start and soft-stop functions to reduce mechanical shock, thereby enhancing operational stability and component durability.

[0004] However, the stability and safety of such barrier gates face severe challenges in extreme conditions such as accidental or malicious vehicle collisions. Existing anti-collision technologies mostly rely on simple mechanical release devices, which separate the gate arm from the actuator after a certain impact force. However, this is a passive, reactive protection that cannot prevent damage to the core mechanism. Therefore, a collision-resistant, high-stability barrier gate with a lifting arm is proposed to address the aforementioned problems. Summary of the Invention

[0005] The purpose of this invention is to provide a collision-resistant, highly stable barrier gate with a lifting arm, thereby addressing the problems mentioned in the background section.

[0006] This invention is implemented as follows: a collision-resistant, high-stability barrier gate includes a gate body, a horizontally mounted gate arm on the gate body, and the gate arm is driven by a control mechanism inside the gate body. It also includes: The swing base is located at the bottom of the gate body and buried in the foundation. The swing base can drive the gate body to swing in the direction of the gate arm being raised. Two information collection terminals are installed on both sides of the gate body, facing the exit and the entrance respectively; When a vehicle enters or exits, the information collection terminal is used to collect multimodal environmental data and upload it to the control system for analysis. When a collision risk is determined, the gate body is swung by the swing base, and the gate arm is lifted by the control mechanism.

[0007] Preferably, the information acquisition terminal includes a support mounted on a foundation, with a multimedia chassis integrating a sensor array fixedly connected to the top of the support; the step of acquiring multimodal environmental data and uploading it to the control system for analysis specifically includes: Multimodal environmental data is collected through an information collection terminal. The multimodal environmental data includes video sequences representing vehicle passage, mechanical vibration signals transmitted by the barrier gate structure, and sound signals representing environmental sounds. Visual motion features are obtained by image analysis of video sequences, spectral energy features are obtained by time-frequency analysis of vibration signals, and voiceprint features are obtained by acoustic analysis of sound signals. Based on the pre-set threat assessment model, visual motion features, spectral energy features, and voiceprint features are aligned and coupled in time series for correlation analysis. When at least two features are detected exceeding their respective safety thresholds within the same time window, a collision risk is identified, and a coordinated start command is generated to control the gate arm lifting and the swing base starting.

[0008] Preferably, the sensor array includes a camera mounted on the top of the multimedia chassis, a vibration sensor installed inside the multimedia chassis, and a directional microphone; the step of acquiring multimodal environmental data through the information acquisition terminal specifically includes: The camera monitors a preset remote monitoring area. When a vehicle enters the area, a synchronous trigger signal is generated. The camera is in a low frame rate energy-saving monitoring mode and runs a lightweight moving target detection algorithm in real time. Based on the synchronous trigger signal, a start command is generated and sent that can switch the camera to a high frame rate and high resolution analysis mode, and a wake-up command is sent to the vibration sensor and directional microphone simultaneously. A hardware timestamp is added to the synchronization trigger signal, and the data sequence is aligned with reference to the first data sample collected by the camera, vibration sensor and directional microphone. The microphone gain and the sampling frequency of the vibration sensor are adjusted based on the vehicle distance and speed information obtained from the moving target detection algorithm.

[0009] Preferably, the multimedia enclosure is provided with a display screen for displaying vehicle information.

[0010] Preferably, the swing base includes a box located at the bottom of the gate body, a rectangular groove is provided on the top of the box, a counterweight roller is rotatably arranged inside the box, a connecting block that cooperates with the rectangular groove and is connected to the bottom of the gate body is fixed on the counterweight roller, and a drive locking component that can drive the counterweight roller to rotate is provided inside the box.

[0011] Preferably, the drive locking component includes two guide rails fixedly connected to the bottom of the housing and spaced apart. A toothed strip is slidably arranged in the guide rails. The surface of the counterweight roller is provided with a toothed structure that cooperates with the toothed strip. The two guide rails are connected by a connecting frame. A drive component is installed on one side of the bottom of the housing. The drive component is connected to the connecting frame through a screw structure. The drive component drives the two toothed strips to move synchronously through the screw structure.

[0012] Preferably, the top of the housing is provided with an elastic protective cover that connects to the bottom edge of the gate body, and the rectangular groove and the connecting block are both located inside the elastic protective cover.

[0013] The anti-collision lifting-arm high-stability barrier gate provided in this embodiment of the invention has the following advantages: The basic structure of this barrier gate is basically the same as that of existing barrier gates. Its key feature is the inclusion of a pre-embedded swing mechanism in the foundation. When a vehicle is detected colliding with the barrier gate, the gate arm is raised to prevent damage. However, existing barrier gates are too slow to respond to sudden collisions. This barrier gate, without altering the main structure, uses the swing mechanism to control the gate body to swing in a manner similar to raising the gate arm. Even if the gate arm movement is not rapid, controlling the swing of the gate body accelerates the raising of the gate arm, allowing it to move away from the danger zone more quickly and avoid being struck. In summary, this barrier gate accelerates the gate arm movement by controlling the swing of the gate body during emergency avoidance, resulting in a faster raising of the gate arm and better protecting the struck gate arm.

[0016] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0017] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0018] like Figure 1 As shown, an embodiment of the present invention provides a high-stability anti-collision barrier gate with a raised arm, including a gate body 1, a horizontally mounted gate arm 2 on the gate body 1, and the gate arm 2 being driven by a control mechanism inside the gate body 1, and further including: The swing base 3 is located at the bottom of the gate body 1 and buried in the foundation 10. The swing base 3 can drive the gate body 1 to swing in the direction of lifting the gate arm 2. Two information collection terminals 4 are installed on both sides of the gate body 1, facing the exit and the entrance respectively; When a vehicle enters or exits, the information acquisition terminal 4 is used to collect multimodal environmental data and upload it to the control system for analysis. When it is determined that there is a risk of collision, the swing base 3 drives the gate body 1 to swing, and the control mechanism drives the gate arm 2 to perform a lifting action.

[0019] In one embodiment of the present invention, the basic structure of this barrier gate is basically the same as that of existing barrier gates. The feature is that a swing base 3 is embedded in the foundation 10. When a vehicle is detected to be impacting the barrier gate, the gate arm 2 will be driven to lift in order to avoid damage to it. However, because the vehicle impact is very urgent, the response speed of existing barrier gates is insufficient. However, without changing the main structure, this barrier gate can control the gate body 1 to swing in a manner similar to lifting the gate arm 2 through the swing base 3. Even if the gate arm 2 does not move quickly, controlling the swing of the gate body 1 can accelerate the lifting action of the gate arm 2, allowing the gate arm 2 to leave the danger zone more quickly and thus avoid being impacted. In summary, when the gate arm 2 is raised for emergency avoidance, this barrier gate accelerates the action of the gate arm 2 by controlling the swing of the gate body 1, thereby making the lifting action of the gate arm 2 faster and thus protecting the impacted gate arm 2.

[0020] In one example of the present invention, such as Figure 1 As shown, the information acquisition terminal 4 includes a support 401 installed on the foundation 10. A multimedia housing 402 with an integrated sensor array is fixedly connected to the top of the support 401. For the control method of the coordinated lifting action of the swing base 3 and the gate arm 2, the information acquisition terminal 4 needs to collect multimodal environmental data and upload it to the control system for analysis. Figure 5 As shown, the specific steps include: S100, collect multimodal environmental data through information collection terminal 4. The multimodal environmental data includes video sequences representing vehicle passage, mechanical vibration signals transmitted by the barrier gate structure, and sound signals representing environmental sounds. S200 performs image analysis on video sequences to obtain visual motion features, performs time-frequency analysis on vibration signals to obtain spectral energy features, and performs acoustic analysis on sound signals to obtain voiceprint features. S300, based on a pre-defined threat assessment model, performs time-series alignment and coupling correlation analysis on visual motion features, spectral energy features, and voiceprint features; S400: When at least two features are detected to exceed their respective safety thresholds within the same time window, it is determined that there is a collision risk, and a coordinated start command is generated to control the lifting of the gate arm 2 and the start of the swing base 3.

[0021] In summary, this invention constructs a highly robust collision threat identification system by integrating visual, vibration, and acoustic perception data. Based on continuous multi-dimensional monitoring of vehicle traffic behavior, it can achieve early and accurate judgment of collision intent. When the system confirms a risk through cross-modal coupling analysis, it employs a defense mechanism involving the coordinated lifting of the gate arm 2 and the swinging of the entire machine. The swinging base 3 drives the movement of the gate body 1, effectively compensating for the response lag of the traditional purely mechanical action of the gate arm 2, significantly shortening the overall time window for hazard avoidance, allowing the gate arm 2 to escape the impact trajectory more quickly. This enables active obstacle avoidance in a very short time, ensuring the safety of the main structure and key components of the barrier gate under extreme collision conditions while maintaining high stability and reliability in daily operation, achieving an effective unity of active defense and normal stable operation. Furthermore, as... Figure 1 As shown, the multimedia chassis 402 is equipped with a display screen 6 for displaying vehicle information. In addition to displaying information such as vehicle license plate and entry / exit time, the display screen 6 can also display the results of the above system analysis.

[0022] like Figure 6 As shown, in a preferred embodiment of the present invention, the sensor array includes a camera 5 disposed on the top of the multimedia chassis 402, a vibration sensor and a directional microphone installed inside the multimedia chassis 402; the step of collecting multimodal environmental data through the information acquisition terminal 4 specifically includes: S101, the camera 5 is used to monitor a preset remote monitoring area. When a vehicle enters the area, a synchronous trigger signal is generated. The camera 5 is in a low frame rate energy-saving monitoring mode and runs a lightweight moving target detection algorithm in real time. S102, based on the synchronous trigger signal, generates and sends a start command that can switch the camera 5 to a high frame rate and high resolution analysis mode, and simultaneously sends a wake-up command to the vibration sensor and the directional microphone; S103, add a hardware timestamp to the synchronization trigger signal, and align the data sequence with reference to the first data sample collected by the camera 5, vibration sensor and directional microphone; S104, adjust the microphone gain and the vibration sensor sampling frequency based on the vehicle distance and speed information obtained from the moving target detection algorithm.

[0023] In one embodiment, the system uses camera 5 in low-power monitoring mode to initially screen moving targets. Once a vehicle enters the remote monitoring area (an area far from the barrier gate), a synchronous trigger signal is generated, simultaneously activating the three sensors and switching to high-performance operating mode. Then, by adding a hardware timestamp to the trigger signal, precise time-series alignment of multi-source data is achieved, constructing a unified analysis timeline. Furthermore, the microphone gain and vibration sensor sampling frequency are dynamically adjusted based on the real-time acquired vehicle motion parameters, forming an adaptive perception optimization oriented towards threat characteristics. This intelligent acquisition strategy not only solves the power consumption problem caused by traditional continuous high-performance acquisition, but also ensures the spatiotemporal consistency and signal quality of visual, vibration, and acoustic signature data through precise synchronization and parameter optimization. This provides a reliable data foundation for subsequent multimodal fusion analysis, ultimately enabling the system to maintain low-power normal operation while possessing rapid response and high-precision identification capabilities for sudden collision threats.

[0024] like Figure 2 , Figure 3 and Figure 4 As shown, in a preferred embodiment of the present invention, the swing base 3 includes a housing 301 located at the bottom of the gate body 1. A rectangular groove 302 is provided on the top of the housing 301. A counterweight roller 303 is rotatably arranged inside the housing 301. A connecting block 304 that cooperates with the rectangular groove 302 and is connected to the bottom of the gate body 1 is fixed on the counterweight roller 303. A drive locking component 7 that can drive the counterweight roller 303 to rotate is provided inside the housing 301.

[0025] In one embodiment, the drive locking component 7 includes two guide rails 701 fixedly connected to the bottom of the housing 301 and spaced apart. A toothed rack 702 is slidably disposed within each guide rail 701. A toothed structure 703 cooperating with the toothed rack 702 is provided on the surface of the counterweight roller 303. The two guide rails 701 are connected by a connecting frame 704. A drive component 705 is installed on one side of the bottom of the housing 301. The drive component 705 is connected to the connecting frame 704 via a lead screw structure 706. The drive component 705 drives the two toothed racks 702 to move synchronously via the lead screw structure 706. The drive component 705 can be in the form of an electric motor, or a hydraulic motor, capable of moving synchronously via a lead screw. The lever structure drives the toothed rack 702 to move. The transmission system formed by the counterweight roller 303 and the toothed rack 702 converts linear drive into precise angular swing, enabling the gate body 1 to quickly deflect along the lifting direction of the gate arm 2. The symmetrical drive structure composed of the double guide rails 701 and the connecting frame 704 ensures the synchronous movement of the toothed racks 702 on both sides, effectively preventing jamming and asynchrony problems and improving the reliability of the system. The drive locking component 7 not only provides stable driving force but also has mechanical self-locking capability at any position, allowing the gate body 1 to be immediately fixed after swinging to any angle. This meets the rapid displacement requirements during emergency collision avoidance and ensures structural stability during daily operation. This compact structural design, which integrates drive and locking, achieves coordinated control of the lifting of the gate arm 2 and the swing of the whole machine within a limited installation space. Through innovative optimization of the mechanical structure, it significantly improves the active anti-collision capability and overall reliability of the barrier gate system. The top of the housing 301 is provided with an elastic protective cover 8 that connects to the bottom edge of the gate body 1. The rectangular groove 302 and the connecting block 304 are both located within the elastic protective cover 8. The elastic protective cover 8 can provide isolation and protection without affecting the swing of the gate body 1. Additionally, as... Figure 2 As shown, a cover plate 9 is provided on one side of the top of the foundation pit (the space required to install the swing base 3). The cover plate 9 can fill the pit and will not obstruct the passage of pedestrians. A detachable structure is provided on the area of ​​the box 301 corresponding to the cover plate 9, which can facilitate the maintenance and repair of the internal mechanical structure of the box.
