Description

Technical Field

[0001] This invention relates to the field of barrier gate technology, specifically to a barrier gate for venue operation. Background Technology

[0002] Entry and exit gates are key equipment for controlling personnel access in venues. Existing gates typically consist of a support base, the gate body, a drive motor, and an information identification device. Their working principle is as follows: When a person approaches the gate, the information identification device (such as an ID card reader or QR code scanner) reads their personal information and confirms their access rights. Then, the controller starts the drive motor, which, through a reduction gearbox, slows down and increases torque, causing the gate body (such as a swing gate or wing gate) to open. After the person passes through, the gate body resets and closes, completing one access control cycle.

[0003] The existing access gates in venues share the following common defects:

[0004] 1. Insufficient impact resistance: Existing barrier gates often use a rigid connection between the main body of the swing gate and the transmission rod. When a pedestrian accidentally collides with the main body of the swing gate, the impact force is directly transmitted to the transmission structure, which can easily lead to damage to transmission components, such as deformation of the transmission rod or damage to the motor due to excessive load, making the barrier gate unable to function properly. For example, when a pedestrian carrying large luggage or pushing a stroller accidentally hits the swing gate, the rigidly connected transmission system is unable to buffer the impact, resulting in high maintenance costs and disruption to the normal passage order of the venue.

[0005] 2. Inadequate accuracy of access control: Existing gates are insufficient in preventing tailgating. Their detection accuracy is limited, making it difficult to accurately identify tailgating behavior, which leads to frequent fare evasion and poses safety hazards and economic losses to venue operations. Summary of the Invention

[0006] (a) Technical problems to be solved

[0007] To address the shortcomings of existing technologies, this invention provides an access gate for venue operations, which solves the problems mentioned in the background section.

[0008] (II) Technical Solution

[0009] To achieve the above objectives, the present invention provides the following technical solution: a venue operation access gate, comprising a support base, a left gate fixedly connected to the upper side wall of the support base near the left side, a right gate fixedly connected to the upper side wall of the support base near the right side, a row of piezoelectric ceramic sensors laid on the upper side wall of the support base in front of the left and right gates, and a transmission rod rotatably connected inside the left and right gates, with a swing gate body rotatably connected to the outer side wall of each transmission rod;

[0010] Each of the transmission rods has a drive wheel fixedly connected to its lower end. A timing belt is drivenly connected to the outer side wall of each drive wheel. A driven wheel is drivenly connected to the inner side of the timing belt away from the drive wheel. A support shaft is fixedly connected to the middle of the driven wheel. A drive helical gear is fixedly connected to the outer side wall of each support shaft. A transmission helical gear is meshed with the outer side wall of each drive helical gear. A transmission shaft is fixedly connected between the transmission helical gears.

[0011] Preferably, the left and right walls of the support base are fixedly connected with limit flanges to improve the stability of the connection between the support base and the ground. The support base is buried underground, and the upper side wall is 1-2 cm away from the ground.

[0012] Preferably, each swing gate body has a signal plate fixedly connected inside for easy labeling of prompts. The swing gate body and the rotating sleeve are fixedly connected, and the rotation of the rotating sleeve can drive the swing gate body to rotate.

[0013] Preferably, a support spring is installed between the rotating sleeve and the transmission rod. The support spring can buffer when a pedestrian collides with the main body of the swing gate, thereby improving the anti-collision effect of the main body of the swing gate.

[0014] Preferably, the left barrier gate is internally equipped with a drive motor and a gearbox. The output end of the drive motor is fixedly connected to the input end of the gearbox, and the output end of the gearbox is fixedly connected to the transmission rod. The drive motor can drive the transmission rod to rotate through the gearbox.

[0015] Preferably, the upper side wall of the left barrier is equipped with an information reading device for reading ID card information, and the upper side wall of the right barrier is equipped with a signal light and a speaker assembly.

[0016] Preferably, the right side wall of the left barrier gate and the left side wall of the right barrier gate are provided with matching inner grooves, each of which matches the swing gate body, making it convenient to store the swing gate body.

[0017] Preferably, the upper sidewall of the support base is equipped with an anti-slip pad, the upper sidewall of the anti-slip pad is provided with anti-slip texture, and the upper sidewall of the support base with the anti-slip pad is flush with the ground.

[0018] (III) Beneficial Effects

[0019] This invention provides an access gate for venue operation, which has the following beneficial effects:

[0020] 1. The swing gate body and the transmission rod of the barrier gate are connected by a rotating sleeve and a support spring. When a pedestrian accidentally collides with the swing gate body, the support spring can buffer the impact force and reduce the damage to the swing gate body and transmission structure. At the same time, after the collision, the elastic force of the support spring can help the swing gate body return to its original position, improving the impact resistance and reliability of the swing gate.

[0021] 2. The transmission structure employed in this invention includes components such as a transmission rod, a driving wheel, a synchronous belt, a driven wheel, a support shaft, a driving helical gear, a transmission helical gear, and a transmission shaft, which work together to realize the opening and closing actions of the swing gate body. This transmission method ensures that the swing gate body has sufficient torque and stability during movement, ensuring smooth and reliable swing gate operation. Simultaneously, the transmission structures inside the left and right gates work together to enable synchronous operation of the left and right swing gates, avoiding passage obstruction or safety hazards caused by asynchronous swing gates.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Example 1:

[0031] like Figure 1-5 As shown, this embodiment of the invention provides an access gate for venue operation, comprising: a support base 1, with limiting flanges 101 fixedly connected to its left and right sides. These limiting flanges 101 allow the support base 1 to be stably buried underground, while maintaining a 1-2 cm distance between its upper sidewall and the ground, ensuring the overall stability of the gate and not obstructing pedestrian passage. A left gate 2 is fixedly connected to the upper sidewall of the support base 1 near the left side, and a right gate 3 is fixedly connected to the upper sidewall of the support base 1. The left and right gates are located on opposite sides of the passage, forming an entrance and exit for controlling personnel passage.

[0032] A row of piezoelectric ceramic sensors 10 is laid on the upper side wall of the support base 1 and in front of the left barrier gate 2 and the right barrier gate 3. These piezoelectric ceramic sensors 10 form a pressure sensor array, which is arranged in a high-density grid pattern and covers 1-2m in front of the barrier gate. 2 The system can accurately detect the location of footsteps. The signal processing unit, connected to the controller, is responsible for collecting data from multiple sensors, performing noise reduction and filtering, converting analog signals into digital signals, and transmitting them to the controller. The controller uses an embedded MCU, such as an STM32, to run a specific algorithm and calculate the number and distribution of footsteps in real time, enabling the detection of people or objects. When a person or object steps on the pressure detection plate, the piezoelectric ceramic sensor 10 converts the sensed pressure signal into an electrical signal output. The signal processing unit performs preliminary processing on these electrical signals, including signal amplification and filtering, to improve signal quality and reliability. After receiving the processed pressure data, the controller analyzes and processes the data according to a preset algorithm to determine the number and distribution of footsteps.

[0033] Both the left and right barrier gates 2 and 3 are internally connected to a transmission rod 504. The lower end of the transmission rod 504 is fixedly connected to a drive wheel 503, which is connected to a driven wheel 802 via a synchronous belt 7. A support shaft 8 is fixedly connected to the middle of the driven wheel 802, and a drive helical gear 801 is fixedly connected to the support shaft 8. The drive helical gear 801 meshes with a transmission helical gear 601, which is fixedly connected to a transmission shaft 6. The transmission structures inside the left and right barrier gates work together. When the drive motor rotates the transmission rod 504, the drive wheel 503 rotates accordingly. Through the synchronous belt 7, it drives the driven wheel 802 to rotate, which in turn causes the drive helical gear 801 on the support shaft 8 to rotate. Through the meshing of the helical gears, it drives the transmission shaft 6 to rotate, ultimately transmitting power to the swing gate body 4 to achieve the opening and closing of the swing gate. This transmission method ensures that the swing gate body has sufficient torque and stability during movement, ensuring smooth and reliable swing gate operation.

[0034] The swing gate body 4 is fixedly connected to the rotating sleeve 502, and a support spring 505 is installed between the rotating sleeve 502 and the transmission rod 504. When a pedestrian accidentally collides with the swing gate body 4, the support spring 505 can buffer the impact force, reducing damage to the swing gate body and transmission structure. At the same time, after the collision, the elastic force of the support spring 505 can help the swing gate body return to its original position, improving the swing gate's impact resistance and reliability.

[0035] The left gate 2 houses a drive motor 5 and a gearbox 501. The output of the drive motor 5 is fixedly connected to the input of the gearbox 501, and the output of the gearbox 501 is fixedly connected to the transmission rod 504. The drive motor 5 drives the transmission rod 504 to rotate through the gearbox 501. The gearbox reduces the rotational speed and increases the torque, ensuring that the swing gate can open and close at an appropriate speed and force. An information reading device 202 is installed on the upper side wall of the left gate 2 to read information such as ID cards, enabling personnel identification. The upper side wall of the right gate 3 is equipped with a signal light 301 and a speaker assembly 302. The signal light emits different colored lights according to the gate's status and pedestrian traffic, while the speaker assembly plays voice prompts, facilitating communication between management personnel and pedestrians regarding the gate's operational status and passage requirements.

[0036] Example 2: Multimodal Fusion Sensing Device

[0037] This embodiment is an extension of Embodiment 1, such as... Figure 6As shown, infrared light curtains 9 are installed on both sides of the barrier gate, working in conjunction with a pressure detection plate. The pressure detection plate consists of piezoelectric ceramic sensors 10, laid on the upper side wall of the support base 1 and located in front of the left barrier gate 2 and the right barrier gate 3, used to detect the stepping position and force of personnel or objects. The infrared light curtains 9 emit and receive infrared light, forming an invisible light curtain. When personnel or objects pass through the light curtain, some infrared light is blocked, thus being detected. This combination of pressure detection plate and infrared light curtains 9 can more comprehensively and accurately detect the passage of personnel, effectively preventing tailgating and fare evasion. The infrared light curtains can detect the body contours and passage positions of personnel, assisting the pressure detection plate in counting personnel and detecting tailgating, improving the reliability and cost-effectiveness of the system.

[0038] The controller simultaneously receives signals from the pressure detection plate and the infrared light curtain 9, fusing these two different types of data. Through a specific algorithm, the pressure data and infrared light curtain data are comprehensively analyzed to determine information such as the passage status, direction, and number of people. For example, when the pressure detection plate detects a stepping signal and the infrared light curtain detects an object passing through it, the controller determines that a person or object is passing through, and then controls the opening or closing of the swing gate body 4. This multimodal data fusion method effectively improves the accuracy and reliability of detection, reducing the occurrence of false positives and false negatives.

[0039] Based on the multimodal fusion perception of the pressure detection board and the infrared light curtain 9, the barrier gate in this embodiment has a stronger anti-tailgating function. When pedestrians pass through normally, the pressure detection board and the infrared light curtain can accurately detect the pedestrian's passage signal and control the swing gate body 4 to close in time, preventing subsequent personnel or objects from tailgating in. If tailgating occurs, such as two people trying to pass through the barrier gate at the same time, the pressure detection board will detect abnormal pressure distribution, and the infrared light curtain will also detect additional objects passing through the light curtain. The controller judges these signals as tailgating behavior, immediately controls the swing gate body 4 to remain closed, and can issue an alarm prompt through the signal light 301 and the speaker component 302 to remind the management personnel to handle the situation, effectively preventing ticket evasion and ensuring the safety and order of venue operation.
