Description

Technical Field

[0001] This utility model relates to the field of intelligent new energy traffic detection technology, specifically to a vehicle outer contour detection and alarm device for multi-source power supply adaptive angle adjustment toll station. Background Technology

[0002] At each toll station area, high-precision camera structures or detection instruments are used to capture information about passing vehicles, such as high-intensity industrial cameras and laser detectors. Considering the complexity of their application scenarios, the following explanation is provided: 1. Conventional instruments of this type are mostly set up with fixed installation, fixed angle, and one-time calibration. For example, single-line or multi-line lidar scans vehicles in the lane at a fixed scanning angle to obtain the vehicle's outer contour by stitching together the point cloud data, and then integrates and analyzes multiple sets of data, which indirectly increases the overall system's computing load. 2. The outdoor operating environment of toll stations is complex and changeable, with many uncontrollable sources of environmental interference. These include backlighting, poor adaptability to severe weather, and permanent blind spots in fixed areas. 3. It should also be noted that there are significant differences in vehicle specifications. For example, the outline of a family sedan can be displayed in the video acquisition area. Conversely, for a large freight vehicle, the outline cannot be fully displayed in the acquisition area, and the outline capture is discontinuous and incomplete. 4. Finally, it should be added that: many current video acquisition structures can be equipped with angle deflection structures, but their rotation direction is mostly on the same plane, making it difficult to achieve wide-area adjustment capability. In addition, when adjusting the acquisition angle, attention should be paid to image issues and the stability of laser emission / reception.

[0003] Based on the above, a solution is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a vehicle outer contour detection and alarm device for multi-source power supply adaptive angle adjustment toll stations, in order to solve the technical problems in the prior art.

[0005] The objective of this utility model can be achieved through the following technical solutions: A multi-source power supply adaptive angle-adjusting toll station vehicle outer contour detection and alarm device includes a fixed support, a built-in control component and multiple monocular cameras. A drive micro motor is installed on the fixed support at the position corresponding to the monocular camera, and a camera bracket is installed along the output shaft of the drive micro motor. The center point of the camera bracket, the output shaft of the drive micro motor, and the center point of the monocular camera are located on the same axis, and a double-headed ball bar is provided between the center point of the camera bracket and the monocular camera. Two electromagnetic actuators are symmetrically mounted on the upper edge of the camera bracket with a double-ended ball joint. A top ball joint is slidably mounted on one of the electromagnetic actuators. A directional groove corresponding to the top ball joint is opened on one side of the monocular camera.

[0006] Furthermore, the top ball stick and the camera bracket are vertically distributed, and the directional groove is curved along the setting direction of the two top ball sticks.

[0007] Furthermore, the two ends of the double-headed cue are spherical structures, and it remains embedded in and freely movable with the camera bracket and the monocular camera.

[0008] Furthermore, the double-ended cue is provided with an outer sleeve and an inner sleeve on the outer wall between the camera bracket and the monocular camera, respectively. The outer sleeve and the inner sleeve are rotatably connected to the double-ended cue, and the outer sleeve and the inner sleeve are also rotatably connected to each other.

[0009] Furthermore, a coiled spring is provided between the outer sleeve and the inner sleeve, and the two ends of the coiled spring are fixedly connected to the inner wall of the outer sleeve and the outer wall of the inner sleeve, respectively.

[0010] Furthermore, the outer sleeve and inner sleeve are equipped with eccentric rods arranged in a circular array along the outer wall of the double-ended club. The eccentric rods are arranged along a triangular position, and the weight of each eccentric rod is not equal.

[0011] Furthermore, the weight-bearing rods are distributed at an angle along the vertical plane on the outer and inner sleeves, with opposite directions of inclination and equal angles of inclination; the weight of a single weight-bearing rod increases radially along the double-ended club, and the weight-bearing rods on the outer and inner sleeves are in opposite directions.

[0012] Furthermore, the built-in control component integrates a vehicle external dimension over-limit detection module and a barrier gate linkage control interface. It can accurately obtain vehicle external parameters such as height, width, and length based on real-time stitching and calculation of multi-view acquired images. When the detected parameters exceed the preset control threshold, it can actively output switch quantity or communication control signal to link the barrier gate equipment to perform a no-lifting-barrier operation. The equipment is equipped with a three-source dual-redundant power supply system of AC power + solar power + battery, which has the functions of seamless switching between multiple power sources, intelligent charging and discharging management, voltage stabilization and distribution, and overload protection, and is suitable for various complex power supply scenarios.

[0013] This utility model has the following beneficial effects: 1. First, a micro-motor is used in conjunction with a camera bracket to achieve a large-scale coarse adjustment of the monocular camera in the horizontal circumference. Then, relying on symmetrically arranged electromagnetic actuators, a top-position ball joint, and a double-headed ball joint with a universal connection structure, multi-dimensional stepless fine adjustment of the camera's pitch and lateral tilt is achieved through differential drive, forming a wide-area adaptive viewing angle adjustment system that links coarse and fine adjustments. The equipment can dynamically adapt the acquisition angle according to different vehicle models, vehicle dimensions, and vehicle lane positions, comprehensively covering the complete outer contours of various small vehicles and large freight vehicles, completely eliminating the permanent blind spots present in traditional fixed-view equipment. Simultaneously, it can actively adjust the viewing angle using a built-in light detection module to avoid environmental interference such as backlight, strong light, and specular reflection. Combined with overload detection and barrier gate linkage mechanisms, it achieves proactive interception and control of overloaded vehicles, significantly improving the accuracy of vehicle outer contour recognition, environmental adaptability, and intelligent control level.

[0014] 2. Secondly, by integrating an outer sleeve, inner sleeve, coiled spring, and reverse unequal weight counterweight on the outer side of the double-ended ball club, angle buffering and anti-shake functions, attitude balance correction, and passive automatic reset are achieved in one integrated system. The coiled spring provides uniform buffering damping during angle adjustment, preventing image jumps and defocusing caused by excessively rapid adjustments. It also effectively absorbs image disturbances caused by outdoor wind vibrations, road vibrations, and equipment shaking, ensuring consistently clear and stable captured images. The reverse gradient weight counterweight generates an adaptive balancing torque, offsetting the center of gravity shift caused by camera angle deflection, preventing issues such as angle drooping, calibration misalignment, and structural looseness that may occur during long-term operation. After the vehicle leaves, passive automatic reset is achieved through the release of energy stored in the coiled spring, requiring no additional drive structure; the structure is simple and highly stable. The supporting three-source dual-redundant power supply system enables seamless millisecond-level switching between multiple power sources, ensuring 24 / 7 uninterrupted operation under conditions such as abnormal mains power and prolonged rainy weather, significantly reducing equipment maintenance frequency and costs, and improving adaptability and operational reliability in complex outdoor scenarios.

[0018] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] Example 1: Refer to Figure 1 It is mainly used to represent the structural diagram of the product, including the general outline of the detector and information signs, while Figure 2 It is mainly used to represent the general structural block diagram of a monocular camera, primarily for the subsequent transmission structure after feedback, thereby enabling... Figure 3 and Figure 4 The transmission structure following the monocular camera is analyzed and disassembled in detail, and then presented. The specific process can be found below: This identifier uses a fixed support 1 as the mounting base for the entire unit. A drive micro-motor 3 is fixedly mounted on the fixed support 1 at the mounting position of the monocular camera 2. The output shaft of the drive micro-motor 3 is fixedly connected to the camera bracket 4. The camera bracket 4 and the monocular camera 2 are connected by a double-headed ball joint 8, forming a universal joint structure. Two sets of electromagnetic actuators 6 are symmetrically mounted on the camera bracket 4. Each electromagnetic actuator 6 has a built-in sliding top ball joint 5, which matches the directional groove 7 on the side wall of the monocular camera 2 to form a fine angle adjustment mechanism. An outer sleeve 9 and an inner sleeve 10 are rotatably fitted onto the outer side of the double-headed ball joint 8, with a coiled spring 11 fixedly connected between them. Multiple sets of unequal-weight, counter-tilted offset rods 12 are mounted in a circular array on the outer wall, forming a posture stabilization and automatic reset mechanism. The built-in control components integrate vehicle type recognition, angle closed-loop control, over-limit size detection, and barrier gate linkage control functions. Combined with a three-source dual-redundant power supply system (mains power, solar power, and battery), it constitutes a complete intelligent identification and control equipment system.

[0020] The device drives the camera bracket 4 to rotate circumferentially via a micro motor 3, enabling coarse horizontal angle adjustment of the monocular camera 2. Two sets of electromagnetic actuators 6 differentially drive the top ball joint 5 to slide along the directional groove 7, using the double-headed ball joint 8 as a universal fulcrum to achieve fine angle adjustment in the camera's pitch and yaw dimensions. During angle adjustment, the coil spring 11 provides buffer damping and accumulates elastic potential energy, while the eccentric rod 12 balances the device's center of gravity in real time, ensuring stable posture. The built-in control component relies on an adaptive matching adjustment strategy based on pre-detection data. Upon detecting a vehicle exceeding the limit, it immediately triggers the barrier gate to enforce a prohibition operation. Furthermore, the video signal acquired by the monocular camera 2 is transmitted to the control terminal, where it undergoes corresponding video analysis algorithms to obtain relevant electrical signals. Commands are then sent to the alarm structure based on these electrical signals. Conventional alarm structures are primarily based on sound and light, such as conventional flashing lights, generating both optical and audible alarm signals. Such lights can be installed on the overall fixed support 1; specific specifications and structures are not limited in this document. The power supply system automatically switches the power supply path according to the mains power operation status, ensuring uninterrupted and stable operation of the equipment throughout the process.

[0021] This embodiment completely solves the problems of large blind spots and poor vehicle compatibility of traditional equipment by using a two-level linkage angle adjustment structure; relying on an integrated attitude stabilization and reset structure, it greatly improves the equipment's outdoor anti-interference capability and long-term calibration accuracy; combined with over-limit linkage control and multi-redundant power supply design, it realizes an integrated upgrade of detection, control and endurance, and can be fully adapted to various engineering scenarios such as highway overload control, highway inspection, and park height restriction control, with extremely strong versatility and practicality.

[0022] Example 2: This example is based on the technical solution of Example 1 above, and details the operation process of each component of the identifier. The fixed support 1 is fixedly installed on the gantry of the toll station lane or on the columns on both sides of the lane. The built-in control component is connected to the ground induction coil and the front radar triggering device of the toll station lane. It can receive the vehicle entry signal in real time and synchronously start the angle adjustment process. This part will not be described in detail: The horizontal circumferential coarse adjustment module consists of a drive micro motor 3 and a camera bracket 4, enabling the camera to rotate and position itself over a wide range horizontally. The pitch and deflection fine adjustment module consists of symmetrically arranged electromagnetic actuators 6, a top ball joint 5, an arc-shaped directional groove 7, and a universal double-headed ball joint 8, enabling multi-dimensional stepless fine adjustment. The built-in control components communicate with the lane inductive loop, front radar, and weighing platform signals, allowing for real-time collection of vehicle traffic status and vehicle model parameters, providing data support for adaptive angle adjustment.

[0023] The fixed support 1 is installed on the toll station gantry or the columns on both sides of the lane. When a vehicle enters the detection area and triggers the ground loop or front radar, the built-in control component synchronously acquires the front detection data such as vehicle type, vehicle length, vehicle height, and lane lateral position. Then, it sends a control signal to the drive micro motor 3. The output shaft of the drive micro motor 3 drives the camera bracket 4 to rotate circumferentially. Because the center of the camera bracket 4, the motor output shaft, and the center of the monocular camera 2 are coaxial, the center of acquisition is always kept coaxial with the lane reference during the rotation. This allows for a large-scale coarse adjustment in the horizontal direction, aligning the vehicle body in the lane and adapting to the lateral deviation of the vehicle.

[0024] After the circumferential coarse adjustment is completed, the built-in control component sends differential control signals to the two sets of electromagnetic actuators 6 according to the vehicle height and length parameters. After the electromagnetic actuators 6 are energized, they drive the top ball rod 5 to perform linear extension and retraction. The end of the top ball rod 5 is embedded in the arc-shaped directional groove 7 on the side wall of the monocular camera 2 and slides along the groove trajectory. When one side of the top ball rod 5 extends and the other side of the top ball rod 5 retracts synchronously, it pushes the monocular camera 2 to perform pitch or yaw movements with the double-headed ball rod 8 as the universal fulcrum. The ball structure at both ends of the double-headed ball rod 8 provides uninterrupted universal support to avoid mechanical interference and jamming. Through the differential coordination of two sets of electromagnetic actuators 6, stepless fine adjustment of pitch and yaw is achieved. For large freight vehicles, the viewing angle is raised to expand the acquisition range and fully cover the front, cargo box and rear of the vehicle; for small vehicles, the viewing angle is lowered to focus the acquisition and avoid image distortion; for vehicles traveling at an angle, automatic yaw compensation is provided to ensure complete outline without truncation; at the same time, the viewing angle can be actively yawed according to the light intensity feedback to avoid backlight, glare and specular reflection, without the need for manual recalibration.

[0025] This two-stage angle adjustment structure can realize full-dimensional, adaptive dynamic adjustment of the acquisition angle, completely eliminate the acquisition blind spots of traditional fixed recognition equipment, accurately adapt to all types of vehicle types such as cars, trucks, and special vehicles, and actively avoid environmental interference such as backlight, glare, and specular reflection. It does not require frequent manual calibration and debugging, and the recognition accuracy and working condition adaptability are greatly improved, fully meeting the compliance standards of various traffic overload detection. The attitude stabilization and reset mechanism consists of an outer sleeve 9, an inner sleeve 10, a coiled spring 11, and a reverse unequal weight offset rod 12, which has the functions of buffering and anti-shaking, center of gravity balancing, and elastic reset. The three-source dual-redundant power supply system consists of a mains power input unit, a solar photovoltaic charging unit, a battery energy storage unit, a seamless switching control unit, and an intelligent power management module, which has the functions of multi-mode power supply, automatic switching, and all-dimensional circuit protection.

[0026] During the entire angle adjustment process of the monocular camera 2, the outer sleeve 9 and inner sleeve 10 of the double-headed ball stick 8 rotate relative to each other as the camera moves, causing the coiled spring 11 between them to undergo elastic deformation. On the one hand, this provides uniform buffer damping for the adjustment action, preventing the electromagnetic action rod 6 from moving too fast and causing the image to jump or become out of focus, thus ensuring the continuity of the captured image during the adjustment process. On the other hand, the elastic characteristics of the coiled spring 11 can effectively absorb the disturbances transmitted by road vibration, wind load, and gantry sway, suppressing continuous image shaking and avoiding image blurring and ghosting. Meanwhile, the outer sleeve 9 and the inner sleeve 10 are arranged in a ring array with multiple sets of eccentric rods 12 in a triangular distribution. The weight of each eccentric rod 12 increases radially, and the eccentric rods 12 on the inner and outer sleeves are tilted in opposite directions and have opposite eccentric directions. When the monocular camera 2 deflects and the center of gravity shifts, the unequal weight eccentric rods 12 arranged in opposite directions automatically form a reverse balancing torque to counteract the deflection torque and prevent the angle from sagging. When the vehicle leaves the detection area, the electromagnetic actuation rod 6 is de-energized and released, and the elastic potential energy stored in the coil spring 11 is released, which drives the monocular camera 2 to automatically return to the initial calibration position without the need for an additional drive mechanism.

[0027] During operation, when the mains power is normal, it directly supplies power to the equipment. At the same time, the solar photovoltaic panels intelligently float charge the battery through the MPPT charging controller. When the mains power is interrupted or the voltage is abnormal, the switching control unit seamlessly switches to battery power in milliseconds, ensuring that the equipment does not stop, restart, or lose data. The battery capacity can meet the long-term battery life requirements of continuous cloudy and rainy days. The power management module provides full-dimensional protection against overcharge, over-discharge, overcurrent, short circuit, and reverse connection, and realizes branch voltage regulation and low-power standby control.
