Description

Technical Field

[0001] The present invention relates to the field of intelligent transportation systems, and in particular to a barrier gate integrated machine and a roadblock machine system that combines license plate recognition technology and collision detection technology, and is particularly suitable for traffic management systems with high security, high reliability, and high efficiency. Background Art

[0002] The parking lot barrier gate is a key device for vehicle access management, and its core functions include license plate recognition, automatic release, toll management, and safety protection such as controllable roadblocks. With the acceleration of urbanization, the management requirements of parking lots are becoming increasingly complex, and intelligent barrier gate systems are gradually becoming the mainstream. Current technologies mainly rely on the collaborative work of modules such as camera license plate recognition, anti-collision radar for vehicle recognition, camera angle adjustment, and electronic payment. However, there are still the following technical bottlenecks and problems in practical applications.

[0003] 1. Problem of camera angle adjustment for license plate capture:

[0004] Traditional license plate recognition cameras are generally installed on one side of the barrier gate. The specific installation methods include installing above the barrier gate box, embedding in the barrier gate box, or installing on a single independent pole near the barrier gate. Regardless of which installation method, the following problems exist in scenarios such as narrow exits, inclined roads, and different vehicle types (such as the coexistence of sedans and trucks): When a large vehicle exits from the left side, the license plate cannot be normally captured due to the camera angle problem, and only vehicles departing from the right side can be normally captured. Fixed-angle cameras are difficult to accurately capture license plate information. Generally, a second license plate capture camera needs to be installed on the right side near the barrier rod to ensure that vehicles in both left and right directions can be recognized. However, this installation method may not be feasible due to space limitations, and it increases the material and construction costs. Some technologies adopt a camera structure with adjustable angles (such as gear transmission + motor drive). The patent "A Parking Lot Barrier Gate" (Patent No. CN221778346U) mentions a solution of installing the camera on the barrier rod and being able to move the camera and adjust the camera angle through a guide rail. This solution solves the problem of the camera shooting angle, but has the problems of complex mechanical structure, slow response speed, and high implementation cost, which is not conducive to engineering.

[0005] 2. Compatibility problem of anti-collision radar with pedestrians, animals, small cars, and large vehicles:

[0006] When using anti-smashing radar to detect vehicles of different sizes (such as small cars and large trucks) at the same time, large vehicles may interfere with radar detection due to physical obstruction or strong reflection signals. For example, the metal shell of a large vehicle reflects a signal that is too strong, which may limit the dynamic range of the radar receiver, causing the target to be lost or misjudged. The problem of false targets generated by some multipath interference can be solved by improving the algorithm and increasing the radar's angular resolution. Therefore, using only one radar sensor is not compatible with the scene where small cars and large cars exist at the same time. In addition, by installing multiple radars at different distances and heights before and after the gate, the compatibility problem of identifying small cars and large cars can be improved, which also increases the cost invisibly. In short, due to the limitations of radar detection, the recognition of special targets such as pedestrians and small animals still needs to be improved.

[0007] 3. Manual gate opening remote control is inconvenient to use:

[0008] Security personnel are required to manually open and close the gates, which may occur when the automatic identification system fails (such as license plate damage, network failure), special vehicles are released, vehicles without license plates are released, non-vehicle objects are released, etc. Existing remote controls for manual gate opening and closing have the following problems: 1) Most of them are one-way transmission, and the remote control side does not know whether the gate receives the signal. When the signal is interfered, it may take multiple presses to see the response; 2) The buttons are single, generally only two buttons for opening and closing the gate. When the gate needs to be opened frequently, a combination of long press and short press is required, which is very cumbersome. There is no indication whether the gate has entered the long opening mode. It may just enter the ordinary opening mode and will automatically close the gate when there is no vehicle; 3) Two different remote controls are used for opening and closing the gate, which is easy to confuse and difficult to manage.

[0009] 4. The roadblock machine starts slowly:

[0010] Traditional roadblock machines rely on motors or hydraulic devices to start, which have a slow start time and sometimes cannot meet the needs of quick opening. In most scenarios, roadblock machines are opened manually by personnel, which further increases the response time and may not achieve the expected explosion-proof effect.

[0011] In short, the existing parking lot gate system still has obvious shortcomings in terms of intelligence and adaptability, and needs further improvement to achieve more adaptable, efficient and safe vehicle management and stronger explosion-proof response capabilities. Summary of the invention

[0012] In order to solve the above problems, the present invention provides a new type of integrated barrier gate and roadblock system, which improves the barrier gate and license plate recognition technology and combines the collision detection function to provide effective license plate recognition, collision detection and anti-smashing functions, which is particularly suitable for narrow exits and special traffic scenarios, including but not limited to the following:

[0013] 1. A license plate recognition camera is installed inside the gate rod, which overcomes the license plate recognition problem caused by poor angle when installing a barrier gate at an entrance or exit with limited space.

[0014] 2. The anti-vehicle-smashing function is executed by changing the shooting angle of the camera, which solves the problem of compatibility in recognizing small cars and large trucks by traditional anti-vehicle-smashing radars.

[0015] 3. The automatic startup problem of the roadblock machine in scenarios where explosion protection is required is solved through anti-collision sensors.

[0016] 4. The problem of cumbersome operation, easy confusion in logic, and unclear indication during traditional manual opening and closing of the gate is solved through a new combined remote control with two-way communication and a display screen.

[0017] 5. Using one camera to switch the shooting angle when opening and closing the gate eliminates the installation of anti-vehicle-smashing radars, capture radars, and the second capture camera, reducing equipment costs and construction costs.

[0018] 6. The system of the present invention can include two parts: an integrated barrier gate machine and a roadblock machine. The integrated barrier gate machine includes functions such as gate rod control, license plate recognition, anti-smashing recognition, collision detection, and roadblock machine control. The license plate recognition camera is installed on the gate rod and close to the middle position of the gate rod. This position can ensure that vehicles approaching from both the left and right sides can be clearly photographed, solving the problem of license plate shooting at narrow exits.

[0037] Traditional license plate recognition cameras are generally installed on one side of the gate. Some are installed above the gate box, some are directly embedded in the gate box, and some are installed on a single pole near the gate. However, no matter which installation method is used, Figure 1 When large and medium-sized vehicles drive out from the left, the license plates cannot be normally photographed due to the camera angle problem. Only the vehicles driving away from the right can be normally captured. Generally, installing a second license plate capture camera near the right side of the gate pole can ensure that the license plates of vehicles driving out from both left and right can be recognized. However, installing the second license plate capture camera may not be achievable due to limited installation space, and it increases the material and construction costs.

[0038] The system designed here includes two major parts: the integrated gate machine and the roadblock machine. Among them, the integrated gate machine includes functions such as gate pole control, license plate recognition, square hitting recognition, collision detection, and roadblock machine control. The license plate recognition camera is installed on the gate pole and close to the middle position of the gate pole. Here, it has very good license plate shooting angles for vehicles coming from both left and right directions, solving the problem of license plate shooting at narrow exits.

[0039] A collision detection sensor is installed inside the barrier rod. When the barrier rod is hit, the turnstile can control the roadblock machine to rise quickly, thus playing an explosion-proof role. The collision sensor can be a combination of one or more sensors. One implementation uses an electronic compass. Assuming that the N pole of the installed electronic compass points to the vehicle departure direction, the direction will not change during normal lifting and lowering of the rod. Since one end of the barrier rod is fixed to the turnstile, when the barrier rod is hit, due to the lever effect, the tail of the barrier rod first deviates towards the vehicle departure direction. At this time, the compass can detect the direction change, and then the system can recognize that it has been accidentally or deliberately hit, and then quickly activate the roadblock machine to prevent the incident from escalating further. Another implementation uses an acceleration sensor. Assuming that the X-axis of the acceleration sensor points to the vehicle departure direction, the Y-axis is along the barrier rod direction, and the Z-axis points to the ground. During normal lifting and lowering of the barrier rod, accelerations will be generated on the Y and Z axes, while there will be no acceleration on the X-axis. When the barrier rod is hit hard, an acceleration will be generated in the X-axis direction, and this acceleration can be used to wake up the system and generate an alarm.

[0040] Figure 2 The camera view angle changes in the open gate and closed gate states.

[0041] In traditional barrier gate systems, to ensure that the barrier rod is not closed until the vehicle has completely left to prevent damage to the vehicle when the barrier rod falls, anti-collision sensors are used in the barrier gate systems. Typically, for example, coils are buried in the ground in front of and behind the barrier rod, and the presence of metal (the vehicle) is detected through the coil induction. This method cannot detect the human body, so there is a risk of the barrier rod hitting people. There are also those that use buried geomagnetic sensors, and there are also problems with not being able to identify the human body. Another example is to install infrared pair sensors at the root and tail positions near the barrier rod. When the infrared rays are blocked, it indicates the presence of a vehicle. When using a single-line infrared pair, it cannot be compatible with vehicles of different heights, such as vehicles with a relatively low tail and engineering vehicles with a high tail. Using a multi-line infrared pair has stronger compatibility, but the cost also increases accordingly, and the infrared pair is easily interfered by rain and snow. Another example is to use a radio frequency anti-collision radar sensor. This sensor can detect whether there is an object within a fan-shaped angle and can distinguish between vehicles and pedestrians through the characteristics of the reflected wave. By adjusting the sensitivity, the recognition distance can be controlled. Generally, the anti-collision radar is directly installed inside the turnstile. However, due to the detection height problem, for scenarios with large vehicles passing through, additional poles need to be installed with multiple radar sensors at different heights to achieve the recognition of large vehicles leaving, which invisibly increases the cost.

[0042] This solution uses a camera to replace the traditional anti-collision solution, and uses a license plate recognition camera for anti-collision recognition at the same time. It can not only identify vehicles, but also pedestrians and even small animals. Since a license plate recognition camera is used, the cost is not increased. Specifically, when the barrier gate is in the closed state, the horizontal angle of the camera faces the direction of the approaching vehicle, and the vertical direction is slightly downward by about 45 degrees. Assuming the viewing angle of the camera is 90 degrees, this angle can completely cover the license plate areas of different vehicle models. When the barrier gate is raised, the orientation of the camera becomes horizontal and directly below the barrier gate, and the vertical direction is 45 degrees downward. At this time, the image captured by the camera can just cover the equivalent areas in front of and behind the barrier gate. Through the algorithm, it is identified whether there are vehicles, pedestrians, animals, and foreign objects in the area where the pole drops, and then it is determined whether to automatically lower the pole (lower the barrier gate).

[0043] Figure 3 Schematic diagram of camera installation

[0044] The hemispherical transparent camera cover is installed at the bottom of the barrier gate, and the camera component is installed inside the camera cover. When the barrier gate is closed (in the horizontal state), the camera faces the direction of the approaching vehicle.

[0045] Figure 4 Camera component

[0046] The camera component includes two parts: the main body and the tail rod. The main body includes parts such as a lens, a camera, a circuit board, and a housing, and is connected to the main board in the turnstile through a flexible cable for power supply and communication. The tail rod includes two parts: a ball head and a connecting rod. The ball head and the connecting rod are fixed by threads. The tail rod is assembled with Figure 5 the camera cover. The ball head is fixed in the ball head bowl in the center. Since part of the spherical surface is reserved at the bottom of the ball head bowl, the ball head will not fall out of the ball head bowl and can rotate freely. See Figure 6 section A of the camera cover. The outside of the ball head bowl is a hemispherical movable spherical surface of the connecting rod. There is a hollowed-out inclined groove of the connecting rod on the movable spherical surface of the connecting rod. This inclined groove can just allow the connecting rod to pass through, and the connecting rod can move freely in the inclined groove of the connecting rod. The two ends of the inclined groove of the connecting rod correspond to the positions of the camera when the barrier gate is closed and opened (i.e., the license plate capture position and the anti-collision detection position).

[0047] Figure 7 Section B of the camera cover and Figure 8 section C of the camera cover show the ball head bowl and the movable spherical surface of the connecting rod at different angles. When the barrier gate is opened, the camera component slides automatically along the inclined groove of the connecting rod to the anti-collision detection position under the action of gravity, and when the barrier gate is closed, the camera component can slide to the license plate capture position. The gravity component of the camera component moving to the license plate capture position when the barrier gate is closed is slightly smaller, and an additional spring can be added to pull the camera component towards the tail of the barrier gate. By controlling the spring force, it will not affect the camera component moving to the anti-collision detection position.

[0048] Figure 9 Camera status when the barrier is closed and Figure 10 camera status when the barrier is opened, respectively showing the shooting angles of the camera assembly at two positions when the barrier rod is opened and closed, and the two positions are just suitable for license plate capture position and anti-collision detection position.

[0049] Figure 11 Circuit block diagram, showing the circuit block diagram of the turnstile system, including the main controller running license plate recognition algorithm, anti-collision recognition algorithm, and all sensing, calculation and control logic functions of the equipment. According to needs, multiple processors can also be used for the main controller, and each processor performs different tasks; the barrier rod drive is used to control the opening and closing of the barrier rod, as well as position detection, obstruction detection, etc.; the roadblock machine drive is used to drive the motor or hydraulic pump of the roadblock machine, and unlocking drive, etc.; Camera 2 is an optional item. When a single turnstile allows two-way passage, Camera 2 is used to capture the license plate of oncoming vehicles in the other direction; the collision detection sensor is used to monitor abnormal collisions of the barrier rod, and then generate alarms and control the roadblock machine; the system is configured with a two-way wireless transceiver circuit for connecting the remote control. Note that power management, storage, interfaces, and other general components are omitted in the block diagram.

[0050] Figure 12 Two-way communication remote control, which is manually controlled by security personnel in case of manual opening of the turnstile. The remote control can communicate with the turnstile host in both directions. The key commands are sent to the turnstile, and at the same time, the turnstile can respond whether the key commands are received and return the current barrier rod status. Typical statuses are: turnstile closed, turnstile open and (when there is no vehicle) automatically close the turnstile, turnstile open and remain open until a new command is received. At the same time, there are indicator lights on the barrier rod indicating different statuses, such as green flashing indicating that the turnstile is open and will automatically close the turnstile, green always on indicating that the turnstile is open and remains open, and red flashing indicating vehicle exit timeout, such as detecting an object under the barrier rod for a long time after opening the turnstile. The remote control is equipped with a low-power display screen for displaying the turnstile status. The key area of the remote control is divided into two areas for entry and exit, and each area contains 3 keys, namely open turnstile, keep turnstile open, and close turnstile. In this way, one remote control can control two turnstiles for entry and exit.

[0051] Traditional roadblock machines rely on motors or hydraulic devices for driving, and both closing and opening are directly driven by the driving device, with a relatively slow action time. Under normal working conditions, the roadblock machine needs to be quickly opened to achieve a fast response for better explosion-proof effect, but the requirement for closing speed is relatively low. Therefore, the roadblock machine is redesigned here. By introducing an opening spring, the roadblock can be quickly opened, while hydraulic drive is used for closing. As Figure 13 shown in the closed state of the roadblock machine, the opening spring is compressed, the roadblock fan is locked, and the hydraulic cylinder is in the extended state. When the roadblock needs to be opened, first unlock the roadblock fan. Since the hydraulic cylinder is in the extended state, it will not hinder the opening of the roadblock fan. Under the action of the elastic force of the opening spring, the roadblock fan quickly opens.

[0052] Figure 14 The open state display of the roadblock machine indicates the open state of the roadblock machine. At this time, the spring is extended and the hydraulic cylinder is in the extended state. When it is necessary to close the roadblock machine, first contract the hydraulic cylinder, pull back the roadblock fan surface, compress the spring, and lock the roadblock fan surface until it reaches the fully closed state, achieving Figure 15 the intermediate state shown during the closing process of the roadblock machine, and then extend the hydraulic cylinder to prepare for the next quick opening, that is, return to as Figure 13 the closed state of the roadblock machine.

[0053] Note that in the embodiment, hydraulic drive is used, but it can be controlled by a motor through partial structural changes.

[0054] While improving the license plate recognition angle, the system of the present invention can effectively reduce the installation and maintenance costs, and has advantages in collision detection, anti-smashing and pedestrian recognition. By combining the license plate recognition camera and the multi-functional sensor, efficient traffic management is achieved, including but not limited to the following:

[0055] 1. Design of the barrier gate integrated machine

[0056] o The license plate recognition camera is installed on the barrier gate rod, near the middle position, and can capture the license plates of vehicles approaching from the left and right directions, avoiding the perspective problems of traditional installation methods.

[0057] o The collision detection sensor is installed inside the barrier gate rod and is used to detect whether the barrier gate rod is collided. When a collision is detected, the system controls the roadblock machine to quickly rise, so as to achieve the explosion-proof effect.

[0058] o The implementation scheme of the collision sensor includes using an electronic compass and / or an acceleration sensor. The electronic compass judges whether a collision occurs by monitoring the direction change of the barrier gate rod when it is hit; the acceleration sensor triggers an alarm by detecting the lateral acceleration generated when the barrier gate rod is hit.

[0059] 2. Anti-smashing and license plate recognition functions

[0060] o Use the license plate recognition camera to replace the traditional anti-smashing radar sensor, and identify whether there are vehicles, pedestrians, animals or other foreign objects through algorithms to decide whether to automatically lower the barrier gate rod.

[0061] o When the barrier gate rod is in the closed state, the viewing angle of the camera will face the oncoming vehicle direction, with a slightly downward vertical angle, covering the license plate areas of different vehicle types. When the barrier gate rod rises, the viewing angle of the camera will be adjusted to the horizontal direction and 45 degrees downward to capture the areas in front of and behind the barrier gate rod for anti-smashing detection.

[0062] 3. Camera component design

[0063] The camera component consists of two parts, the main body and the tail rod. The tail rod is used in conjunction with the camera cover and has the ability to automatically adjust. The camera component automatically slides to an appropriate position for license plate capture or anti-collision detection according to the open or closed state of the barrier arm.

[0064] The camera cover is designed with a hemispherical transparent cover to ensure that the camera can flexibly capture images from different angles.

[0065] 4. Roadblock Machine Design

[0066] The roadblock machine adopts a new design scheme, combining an opening spring and hydraulic drive to achieve a faster response speed. It opens quickly through the spring force when opening and closes slowly using hydraulic drive when closing. This design provides better explosion-proof effects while maintaining the high efficiency of the system.

[0067] The embodiments of the present invention also include the following aspects, significantly improving the performance of the system and the user experience.

[0068] (1) A camera is installed on the barrier arm, and the shooting angle is automatically switched when the barrier arm opens and closes, and it is used for license plate recognition and anti-collision (vehicle, person) recognition at the same time

[0069] By cleverly installing a camera on the barrier arm and designing it to automatically switch the shooting angle when the barrier arm opens and closes, the dual functions of license plate recognition and anti-collision recognition are achieved. Specifically, when the barrier arm is in the closed state, the viewing angle of the camera is adjusted to an angle suitable for shooting the license plate to ensure that the license plate information of the vehicle can be clearly and accurately recognized; when the barrier arm opens, the viewing angle of the camera automatically switches to an angle suitable for detecting the area under the barrier arm, which is used to identify targets such as vehicles, pedestrians, and animals, thereby realizing the anti-collision function. This design not only avoids the complex structure of installing multiple cameras and radars in the traditional system, simplifies the system composition, reduces the equipment cost and construction difficulty, but also improves the reliability and stability of the system. At the same time, since the viewing angle switching of the camera is automatically completed without manual intervention, it is also more convenient in operation, effectively improving the intelligent level of the system. In addition, this design has strong adaptability and can be applied to different types of vehicles and various complex entrance and exit environments. Whether it is a narrow passage or an inclined road surface, it can ensure good recognition effects, providing strong technical support for entrance and exit management.

[0070] (2) A combined manual gate controller with two-way communication, status feedback, and status display

[0071] Traditional manual turnstile controllers usually have a single function, are inconvenient to operate, and cannot understand the status of the turnstile in real time, bringing many inconveniences to the operation of security personnel. The combined manual turnstile controller designed in the present invention, which has two-way communication, status feedback, and status display, effectively solves these problems. This controller can not only send control commands to the turnstile, but also receive the status feedback information of the turnstile and display it in real time through a low-power display screen, enabling security personnel to understand the working status of the turnstile at any time, such as whether the turnstile rod is in the open or closed state, and whether there are vehicles or pedestrians passing through. This function of two-way communication and status feedback greatly improves the accuracy and reliability of manual operation, avoiding misoperations and potential safety hazards caused by poor information communication. At the same time, the key area of the controller is divided into two areas for entry and exit, and each area contains three keys: open the turnstile, keep the turnstile open, and close the turnstile. The functions are clear and the operation is simple, so that security personnel can quickly get started and improve work efficiency. In addition, this controller also has the advantages of small size, easy to carry, and low power consumption, and is suitable for use in various environments, providing a more convenient and efficient control means for access management.

[0072] (3) Innovative roadblock machine design, introducing the combination of opening spring and hydraulic drive

[0073] In the design of the roadblock machine, by introducing the combination of the opening spring and hydraulic drive, the functions of rapid opening and stable closing are realized. Specifically, when it is necessary to open the roadblock, first unlock the roadblock fan. Since the hydraulic cylinder is in the extended state, it will not hinder the opening of the roadblock fan. Under the elastic force of the opening spring, the roadblock fan can be quickly opened to meet the rapid response requirements in explosion-proof scenarios. When it is necessary to close the roadblock machine, first contract the hydraulic cylinder, pull back the roadblock fan, compress the spring, and lock the roadblock fan until it is in the fully closed state, and then extend the hydraulic cylinder to prepare for the next rapid opening. This design not only improves the response speed of the roadblock machine, enabling it to quickly close the access in case of emergency to prevent illegal elements from breaking in, but also ensures the stability during closing, avoiding impacts and damages caused by rapid closing. At the same time, through the combination of hydraulic drive and spring, the failure rate and maintenance cost of the equipment are also reduced, improving the reliability and economy of the system. In addition, this design also has the advantages of simple structure, easy installation and maintenance, etc., and is suitable for use in various access environments, providing a strong guarantee for the safety management of access.

[0074] (4) Diversified design of collision detection sensors

[0075] In order to improve the accuracy and reliability of collision detection, the present invention diversifies the design of the collision detection sensor and adopts a combination of multiple sensors such as an electronic compass and an acceleration sensor. The electronic compass determines whether a collision has occurred by detecting changes in the direction of the barrier arm. When the barrier arm is collided, due to the lever effect, the tail of the barrier arm first deflects towards the vehicle exit direction, and the electronic compass can detect the direction change, so that the system can identify the collision and quickly activate the roadblock machine to prevent the event from escalating further. The acceleration sensor determines whether a collision has occurred by detecting changes in the acceleration of the barrier arm in various directions. When the barrier arm is severely collided, an acceleration will be generated in the X-axis direction, and this acceleration can be used to wake up the system and generate an alarm. This diversified design not only improves the sensitivity and accuracy of collision detection, but also enhances the anti-interference ability of the system, can effectively handle various complex collision situations, and provides strong technical support for the security management of the entrance and exit. At the same time, the installation and debugging of these sensors are relatively simple, the cost is low, and they have high practicability and economy.

[0076] (V) System Integration and Optimization

[0077] The present invention not only innovatively designs each component and function, but also integrates and optimizes the entire system, enabling the components to work together and exert the best performance. For example, through the coordination and management of the main controller, the organic combination of functions such as license plate recognition, anti-collision recognition, collision detection, and roadblock machine control is realized, ensuring the efficient operation of the system; through the reasonable design of the circuit framework, stable connection and communication between modules are achieved, improving the reliability and stability of the system; through the optimization of software algorithms, the accuracy of license plate recognition and anti-collision recognition is improved, enhancing the intelligent level of the system. This design concept of system integration and optimization not only improves the overall performance of the present invention, but also provides convenience for subsequent upgrades and expansions, enabling it to better adapt to the changing market demands and technological developments.

[0078] (VI) Sensor Replacement Solutions

[0079] In terms of collision detection sensors, in addition to electronic compasses and acceleration sensors, other types of sensors, such as pressure sensors and displacement sensors, can also be considered to further improve the accuracy and reliability of collision detection. Pressure sensors can directly detect the size of the external force on the gate rod. When the pressure exceeds the set threshold, it can be determined that a collision event has occurred, thereby triggering corresponding protective measures. This sensor has the characteristics of fast response speed and high accuracy, and can effectively avoid misjudgment caused by external force impact. Displacement sensors can determine whether a collision has occurred by detecting the displacement change of the gate rod. When the gate rod has an abnormal displacement, the system can respond in time and take corresponding protective measures. This sensor is very sensitive to the detection of tiny displacements and can effectively improve the sensitivity of collision detection. In addition, it is also possible to consider using a combination of multiple sensors, and through data fusion technology, further improve the accuracy and reliability of collision detection, and provide more powerful technical support for the safety management of entrances and exits.

[0080] (VII) Remote control function expansion

[0081] For two-way communication remote controllers, more functions can be considered, such as remote monitoring, fault alarm, and authority management, to meet the needs of different scenarios and improve the intelligence level of the system. The remote monitoring function allows security personnel to view the operating status and video surveillance images of the gate machine in real time away from the entrance and exit, so as to understand the situation on site in a timely manner and make corresponding decisions. The fault alarm function can send alarm information to security personnel in a timely manner when a system failure occurs, indicating the type and location of the fault, facilitating rapid maintenance and processing, and reducing system downtime. The authority management function can set different operating permissions for users of different levels to ensure the security and stability of the system and prevent safety hazards caused by unauthorized operations. In addition, it is also possible to consider adding functions such as voice prompts and gesture control to further improve the intelligence level and user experience of the remote controller, and provide a more convenient and efficient operation method for entrance and exit management.

[0082] (VIII) Driving mode of roadblock machine

[0083] In terms of the driving methods of road blockers, in addition to hydraulic drive and motor control, other driving methods can be explored, such as pneumatic drive, electromagnetic drive, etc., to further improve the response speed and reliability of road blockers. Pneumatic drive uses compressed air as the power source, with advantages such as fast response speed, low cost, and simple maintenance, and is suitable for scenarios with high requirements for response speed. Electromagnetic drive uses electromagnetic force to drive the movement of road blockers, with advantages such as high control precision, fast response speed, and low noise, and can achieve precise control of road blockers while ensuring fast response. In addition, a combination of multiple driving methods can also be considered, such as the combination of pneumatic drive and electromagnetic drive, to give play to their respective advantages and further improve the performance and reliability of road blockers. At the same time, with the continuous development of technology, the development trends of new driving technologies can also be concerned, such as ultrasonic drive, magnetorheological drive, etc., and introduce them into the design of road blockers in a timely manner to provide more advanced and reliable equipment support for the security management of entrances and exits.

An explosion-proof brake system, comprising: License plate recognition cameras, mounted on gate bars to capture vehicle license plates from multiple directions; Impact detection sensors, embedded in the gate bar, detect abnormal impacts and trigger a rapid response mechanism; and A roadblock system that quickly raises when unauthorized or forced passage is detected.

2. The system of claim 1, wherein the collision detection sensor comprises an electronic compass, which detects a change in direction and triggers the roadblock to rise when the gate bar is struck.

3. The system according to claim 1, wherein the collision detection sensor comprises an acceleration sensor, which detects the acceleration change in the direction of the vehicle when the gate rod is hit, and triggers an alarm or a protective response mechanism.

4. The system of claim 1, wherein the license plate recognition camera faces the direction of the oncoming vehicle to perform license plate recognition when the gate bar is in a closed state, and when the gate bar is raised, the camera is automatically repositioned to monitor whether there are obstacles in the area below the gate bar.

5. The system of claim 4, wherein the repositioning of the camera is achieved by a mechanical linkage mechanism that utilizes gravity and guide grooves to move the camera to different positions along with the gate bar.

6. The system according to claim 4, wherein the license plate recognition camera is also used for anti-smashing detection, identifying vehicles, pedestrians and small obstacles to determine whether it is safe to drop the pole.

7. The system according to claim 1, comprising a two-way communication wireless remote controller for manually controlling the gate and providing real-time feedback on the gate status.

8. The system according to claim 1, wherein the roadblock machine adopts a spring-assisted rapid opening mechanism, and its closing is controlled by hydraulic drive to achieve efficient explosion-proof response.

9. A method for explosion-proof brakes, comprising the following steps: Collect license plate recognition camera images and perform license plate recognition when the gate bar is in the closed state; Collect data from collision detection sensors and analyze whether there is an abnormal collision; When an abnormal collision is detected, the barrier is controlled to rise quickly to prevent unauthorized or forced passage; when no abnormality is detected, the barrier is controlled to rise according to the license plate recognition result or external command.

10. The method according to claim 9, wherein the method further comprises the following steps: The electronic compass is used to detect the change in the direction of the gate rod. If the direction deviation exceeds the set threshold, the explosion-proof response is triggered; Alternatively, the acceleration sensor can detect the acceleration change in the direction of the vehicle, and if it exceeds the set threshold, an explosion-proof response is triggered.
