Description

Technical Field

[0001] The present invention relates to the technical field of intelligent access control, and in particular to an intelligent access control system. Background Art

[0002] Smart access control machine is an intelligent access control management device based on artificial intelligence technology, which is used to achieve security control and record management of people entering and leaving various places. It is not only highly safe and practical, but also can improve the efficiency and convenience of access control management. The access control machine is the core control device of the access control system. It uses a large-capacity storage chip as a storage carrier. It has the advantages of reliable data storage, no data loss during power failure, and integrated management and automatic control. It is widely used in access control, attendance management, security alarm, parking lot management, elevator control, building automation, etc. in smart buildings or smart communities. It can also be linked with other systems to achieve a variety of control functions.

[0003] In vehicle management scenarios, access control machines and barriers are often integrated into the same system to form an access control system. The access control system usually consists of an access control machine, access control controller, barrier, barrier controller, license plate recognition camera, and management system. Data is processed and managed in the background management system, and personnel or vehicles are identified and authorized through hardware devices and software programs to achieve efficient and safe management of gates and vehicles entering and leaving roads.

[0004] At present, the existing access control system usually uses a motor to control the gate during use. The opening and closing of the gate is controlled by controlling the forward and reverse rotation of the motor. After the gate is opened or closed, there is no other braking device to lock and fix the gate. There is a risk of the gate being opened by external force after it is closed, and the risk of the gate suddenly falling and closing after it is opened, resulting in certain safety hazards in the access control system. Summary of the invention

[0005] The purpose of the present invention is to provide an intelligent access control system to lock and fix the barrier after it is opened or closed, so as to prevent the barrier from suddenly falling and closing when opened or being opened by external force when closed, thereby improving the security of the access control system.

When the driving member drives the transmission shaft to rotate, the transmission shaft can drive the gate rod to rotate synchronously. A clamp assembly is arranged on one side of the transmission shaft, and the clamping opening of the clamp assembly is driven to close or open by the driving member. The driving member is electrically connected to the driving member. When the gate rod needs to rotate, the driving member drives the clamping opening to open and release the transmission shaft. At the same time, the driving member drives the transmission shaft to rotate, and the gate rod is driven to rotate to open or close through the transmission shaft. When the gate rod needs to stop rotating, the driving member is closed and stops driving the transmission shaft. The transmission shaft stops rotating due to the loss of the rotational power provided by the driving member, so that the gate rod stops at a set fixed position; at the same time, the driving member drives the clamping opening to close, and clamps the transmission shaft through the clamp assembly, so that the transmission shaft cannot rotate freely due to the constraint of the clamp assembly, and then the gate rod cannot rotate freely, so that the gate rod can be stably maintained in a closed state or an open state, thereby preventing the gate rod from rotating and opening under the action of external force when in the closed state or suddenly falling and closing in the open state, thereby improving the safety of the access control system.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0056] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0057] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0058] See also Figure 1 The embodiment of the present invention provides an intelligent access control system, including a gate 1, a brake device 2 and a chassis 3. The gate 1 includes a gate rod 11, a transmission shaft 12 and a driving member 13. One end of the transmission shaft 12 is connected to the power output end of the driving member 13, and the other end of the transmission shaft 12 is connected to the gate rod 11. The driving member 13 is used to drive the transmission shaft 12 to rotate, and the gate rod 11 is driven to rotate by the transmission shaft 12. The gate rod 11 rotates to open or close, so as to realize the control of people or vehicles entering and exiting the door or the road; the brake device 2 is installed in the chassis 3, and the brake device 2 includes a clamp assembly The clamp assembly 21 has a clamping opening 212 that can be opened and closed. The clamp assembly 21 is arranged on one side of the transmission shaft 12, and the clamping opening 212 is opposite to the transmission shaft 12; the driving assembly 22 is connected to the clamp assembly 21 to drive the clamping opening 212 to close or open. When the clamping opening 212 is closed, the clamping opening 212 is clamped on the transmission shaft 12, so that the transmission shaft 12 cannot rotate; when the clamping opening 212 is opened, the clamping opening 212 releases the clamping and fixing of the transmission shaft 12, so that the transmission shaft 12 can rotate under the drive of the driving member 13.

[0059] The driving assembly 22 is electrically connected to the driving member 13. When the gate rod 11 needs to rotate, the driving assembly 22 drives the clamping mouth 212 to open and release the transmission shaft 12. At the same time, the driving member 13 is started to drive the transmission shaft 12 to rotate, and the gate rod 11 is driven by the transmission shaft 12 to rotate and open to allow people or vehicles to pass; or the gate rod 11 is driven to rotate and close to block the movement of people or vehicles. When the gate rod 11 needs to stop rotating, the driving member 13 is closed and the driving work on the transmission shaft 12 is stopped. The transmission shaft 12 stops rotating due to the loss of the rotational power provided by the driving member 13, so that the gate rod 11 stops at the set fixed position; at the same time, the driving component 22 drives the clamping mouth 212 to close, and clamps the transmission shaft 12 through the clamp component 21, so that the transmission shaft 12 cannot rotate freely due to the constraint of the clamp component 21, and then the gate rod 11 cannot rotate freely, so that the gate rod 11 can be stably maintained in the closed state or the open state, thereby preventing the gate rod 11 from rotating and opening under the action of external force when in the closed state or suddenly falling and closing in the open state, thereby improving the security of the access control system.

[0060] In some embodiments, the chassis 3 has a housing cavity, the driving member 13 and the brake device 2 are both disposed in the housing cavity of the chassis 3, the transmission shaft 12 is rotatably connected to the chassis 3, and the transmission shaft 12 at least partially extends out of the chassis 3 and is connected to the brake rod 11. The chassis 3 provides a mounting carrier and protection for the driving member 13, the brake device 2, and the transmission shaft 12, so as to prevent the driving member 13 and the brake device 2 from being exposed and damaged. Figure 1 The chassis 3 is a rectangular box that can be fixed on the ground.

[0061] In some embodiments, the intelligent access control system further includes an access control machine 31 and a controller, and the access control machine 31 and the driving member 13 are electrically connected to the controller respectively. The access control machine 31 can be installed on the chassis 3. The access control machine 31 identifies the passing vehicles. When the vehicle identification passes, the driving member 13 drives the gate rod 11 of the gate 1 to open to ensure the smooth passage of the vehicle; when the access control identification of the vehicle fails, the driving member 13 does not move, so that the gate rod 11 of the gate 1 remains in the closed state. It should be noted that the license plate recognition method of the access control machine 31 for the vehicle is a prior art, and the present invention will not be described in detail.

[0062] In some embodiments, the clamp assembly 21 includes two clamps 211, which are hinged to the chassis 3. One ends of the two clamps 211 are hinged to each other to form a hinged end 213 of the clamp assembly 21, and the other ends of the two clamps 211 are relatively spaced apart to form a clamping opening 212 of the clamp assembly 21. By operating the hinged ends 213 of the two clamp assemblies 21, the ends of the two clamps 211 away from the hinged ends 213 are brought closer to each other to achieve the closure of the clamping opening 212; or the ends of the two clamps 211 away from the hinged ends 213 are moved away from each other to achieve the opening of the clamping opening 212.

[0063] In order to drive the two clamps 211 to open and close relative to each other, in some embodiments, the driving assembly 22 includes a push rod 222 and a push rod driving member 223. The push rod 222 is arranged on one side of the transmission shaft 12, and one end of the push rod 222 is connected to the hinge end 213 of the clamp assembly 21; the push rod driving member 223 is connected to the end of the push rod 222 away from the clamp assembly 21, and the push rod driving member 223 drives the push rod 222 to perform linear reciprocating motion relative to the chassis 3, so that the clamping opening 212 is opened or closed. The movement direction of the push rod 222 is perpendicular to the central axis of the transmission shaft 12. The push rod 222 performs linear reciprocating motion to approach or move away from the transmission shaft 12. When the push rod driving member 223 drives the push rod 222 to move close to the transmission shaft 12, the push rod 222 drives the hinged end 213 of the clamp assembly 21 to move close to the transmission shaft 12. Since the clamp 211 is hinged to the chassis 3, when the hinged end 213 approaches the transmission shaft 12, it drives the end of the clamp 211 away from the hinged end 213 to swing, so that the clamping opening 212 formed by the two clamps 211 opens, and the constraint on the transmission shaft 12 is released. When the push rod driving member 223 drives the push rod 222 to move away from the transmission shaft 12, the push rod 222 drives the hinged end 213 of the clamp assembly 21 to move away from the transmission shaft 12 synchronously, so that the end of the clamp 211 away from the hinged end 213 swings in the opposite direction, and the clamping opening 212 is closed and clamped on the transmission shaft 12. A mounting frame 221 is fixedly provided in the chassis 3, the mounting frame 221 is provided on one side of the transmission shaft 12, the mounting frame 221 is fixed to the inner wall of the chassis 3, and each clamp 211 is hinged on the mounting frame 221. The mounting frame 221 provides mounting support for the clamp 211.

[0064] In some embodiments, the clamp 211 includes a first clamp arm 2111 and a second clamp arm 2112, the first clamp arm 2111 is hinged to the chassis 3, specifically, it can be hinged to the mounting frame 221, one end of the second clamp arm 2112 is hinged to the first clamp arm 2111, and the other end of the second clamp arm 2112 is hinged to the second clamp arm 2112 of another clamp 211, forming a hinged end 213 of the clamp assembly 21. When the hinged end 213 of the clamp assembly 21 moves, the second clamp arm 2112 swings, and the first clamp arm 2111 is driven to swing by the second clamp arm 2112, so that the clamping openings 212 of the two clamps 211 are opened or closed.

[0065] The push rod driving member 223 provides power for the linear reciprocating motion of the push rod 222. In some embodiments, the push rod driving member 223 includes an electromagnet 2231, a magnetic block 2232 and a first elastic member 2233. The electromagnet 2231 is fixed to the chassis 3, specifically, it can be fixed to the side of the mounting frame 221 away from the transmission shaft 12, and the electromagnet 2231 is connected in series with the driving member 13; the magnetic block 2232 is fixed to the end of the push rod 222 away from the clamp assembly 21; one end of the first elastic member 2233 is connected to the magnetic block 2232, and the other end of the first elastic member 2233 is connected to the chassis 3, specifically, connected to the mounting frame 221. The electromagnet 2231 is connected in series with the driving member 13, and the electromagnet 2231 and the driving member 13 are connected to the same power supply. When the driving member 13 is started, the power supply also supplies power to the electromagnet 2231. After being energized, the electromagnet 2231 attracts the magnetic block 2232, so that the magnetic block 2232 overcomes the elastic force of the first elastic member 2233 and moves toward the direction close to the electromagnet 2231. When the magnetic block 2232 moves, it drives the push rod 222 to move synchronously, so that the push rod 222 moves close to the transmission shaft 12, drives the clamping mouth 212 of the clamp assembly 21 to open and release the transmission shaft 12, so that the driving member 13 can drive the transmission shaft 12 to rotate, and drives the gate rod 11 to rotate through the transmission shaft 12. When the gate rod 11 needs to stop rotating, the driving member 13 is powered off and stops working, the electromagnet 2231 is powered off synchronously, the magnetic block 2232 loses the suction effect of the electromagnet 2231, and the magnetic block 2232 moves to a direction away from the electromagnet 2231 under the elastic force of the first elastic member 2233 to reset. When the magnetic block 2232 moves, it drives the push rod 222 to move synchronously, so that the push rod 222 moves away from the transmission shaft 12 to reset, and drives the clamping opening 212 of the clamp assembly 21 to close and clamp on the transmission shaft 12, so as to prevent the gate rod 11 from being turned to open by external force or the gate rod 11 from falling suddenly when it is opened, thereby improving the safety of the access control system. The first elastic member 2233 is a spring, which is sleeved on the push rod 222. When the spring is in a natural state, the magnetic block 2232 is away from the electromagnet 2231, the push rod 222 is away from the transmission shaft 12, and the clamping opening 212 of the clamp assembly 21 is closed and clamped on the transmission shaft 12. After the electromagnet 2231 is energized, the magnetic block 2232 moves close to the electromagnet 2231 to put the first elastic member 2233 in a compressed state, and has an elastic force to drive the magnetic block 2232 to move in the opposite direction and reset. The structural form of the push rod driver 223 is adopted, so that the push rod driver 223 and the driver 13 can work synchronously, so that the driver 13 drives the rotation of the transmission shaft 12 and the opening of the clamping opening 212 are synchronized, and the driver 13 drives the transmission shaft 12 to stop rotating and the clamping opening 212 is synchronized, so as to ensure that the clamp assembly 21 brakes the transmission shaft 12 in time, and improve the safety of the access control system.

[0066] It should be noted that, in other embodiments, the push rod driving member 223 may also be a power component such as a cylinder, an electric telescopic rod, etc. that can drive the push rod 222 to perform linear reciprocating motion.

[0067] In some embodiments, the barrier 1 further includes a connecting shaft 14 and a second elastic member 15, one end of the connecting shaft 14 is connected to the gate rod 11, and the other end is connected to the transmission shaft 12, and at least one end of the connecting shaft 14 is connected to be rotatably connected, and the rotation axis of the connecting shaft 14 and the rotation axis of the transmission shaft 12 are perpendicular to each other; one end of the second elastic member 15 is connected to the gate rod 11, and the other end of the second elastic member 15 is connected to the transmission shaft 12. The transmission shaft 12 is arranged parallel to the ground, and the transmission shaft 12 and the gate rod 11 are arranged vertically. The connecting shaft 14 is located outside the chassis 3 and is arranged vertically to the ground, and the connecting shaft 14 is perpendicular to the transmission shaft 12 and the gate rod 11. When the transmission shaft 12 rotates around its own axis, it drives the connecting shaft 14 and the gate rod 11 to rotate synchronously around the central axis of the transmission shaft 12, so that the gate rod 11 rotates in the vertical plane to open or close. When the gate rod 11 is in the closed state, and the driver of the vehicle fails to brake in time or the vehicle suddenly breaks down, causing the vehicle to move forward and collide with the gate rod 11, the gate rod 11 will overcome the elastic force of the second elastic member 15 and rotate around the connecting shaft 14 in a direction parallel to the ground by a certain angle to prevent the gate rod 11 from being broken by the vehicle, thereby improving the safety of the gate rod 11 to a certain extent. After the vehicle moves away from the gate rod 11, the gate rod 11 rotates in the opposite direction around the connecting shaft 14 under the elastic force of the second elastic member 15 to reset. The second elastic member 15 is a tension spring, located outside the chassis 3.

[0068] In some embodiments, the driving member 13 has a power output shaft 131, and the transmission shaft 12 is connected to the power output shaft 131 in a non-rotatable manner, so that the power output shaft 131 can drive the transmission shaft 12 to rotate synchronously, and the transmission shaft 12 can slide axially relative to the power output shaft 131, so that after the gate rod 11 is hit, the transmission shaft 12 can have a certain axial displacement relative to the power output shaft 131 of the driving member 13, so as to avoid the gate rod 11 being excessively hit and causing the transmission shaft 12 and the power output shaft 131 to break, further improving the safety of the gate 1. The driving member 13 is a motor, and the power output shaft 131 is a motor shaft. One end of the transmission shaft 12 close to the power output shaft 131 is a spline shaft, and the other end of the transmission shaft 12 is an optical axis, and one end of the optical axis of the transmission shaft 12 extends out of the chassis 3 and is rotatably connected to the chassis 3. The power output shaft 131 is a hollow shaft structure, and one end of the spline shaft of the transmission shaft 12 is slidably connected to the power output shaft 131 to achieve a non-rotating connection between the transmission shaft 12 and the power output shaft 131 and axial sliding relative to the power output shaft 131 .

[0069] In an emergency situation where the gate rod 11 needs to be opened quickly to release vehicles, for example, when a fire truck or an ambulance enters or exits, it fails to pass the access control identification of the access control machine 31 and cannot pass through the gate 1 quickly, which will affect subsequent rescue; or, the access control system is powered off and cannot control the opening and closing of the gate rod 11. In some embodiments, the intelligent access control system also includes a release device 4, which is arranged in the chassis 3, and the release device 4 includes a rotating member 41 and a moving member 42, and the rotating member 41 is coaxially fixedly sleeved on the transmission shaft 12, so that when the rotating member 41 rotates, the transmission shaft 12 can be driven to rotate synchronously; the moving member 42 is connected to the chassis 3, and the moving member 42 is arranged on one side of the rotating member 41, and has a joint portion for cooperating with the rotating member 41 and an abutting portion 421 for abutting with the push rod 222 or the magnetic block 2232, and the abutting portion 421 is arranged at one end of the moving member 42 away from the rotating member 41; the moving member 42 can perform linear reciprocating motion relative to the chassis 3 in a direction close to or away from the transmission shaft 12. During the moving stroke, the moving member 42 drives the clamp assembly 21 to open the clamping opening 212 and rotates the rotating member 41. The moving member 42 is movably arranged in the chassis 3. The moving direction of the moving member 42 is parallel to the moving direction of the push rod 222, and both are perpendicular to the central axis of the transmission shaft 12. The moving member 42 and the brake device 2 are located on the same side of the transmission shaft 12. During the movement of the moving member 42 toward the transmission shaft 12, the contact portion 421 of the moving member 42 can contact the push rod 222 or the magnetic block 2232, thereby driving the push rod 222 to move synchronously, so that the push rod 222 approaches the transmission shaft 12, until the moving member 42 contacts the rotating member 41. At this time, the push rod 222 drives the clamp assembly 21 to open the clamping opening 212 to release the transmission shaft 12. At the same time, the engaging portion of the moving member 42 cooperates with the rotating member 41 to drive the rotating member 41 to rotate, and the transmission shaft 12 is driven to rotate by the rotating member 41, so that the gate rod 11 rotates and opens, and fire trucks, ambulances, etc. are released. The release device 4 is linked with the brake device 2 to control, and when the release device 4 is operated, the brake device 2 releases the clamping and braking effect on the transmission shaft 12, ensuring that the gate rod 11 can be opened urgently through the release device 4.

[0070] After the vehicle is released in an emergency, the chassis 3 can be opened, and the push rod 222, the driving assembly 22, the moving part 42, etc. can be reset manually.

[0071] It should be pointed out that the abutment portion 421 of the moving member 42 can abut against the push rod 222 or the push rod driving member 223. The magnetic block 2232 is provided with a protrusion 22321 extending toward the moving member 42. The abutment portion 421 abuts against the protrusion 22321 during the movement of the moving member 42. The protrusion 22321 pushes the magnetic block 2232 to overcome the elastic force of the first elastic member 2233 and move close to the electromagnet 2231, driving the push rod 222 to move close to the transmission shaft 12. After the emergency release of the vehicle is completed, the moving member 42 is manually reset, and the protrusion 22321 loses the abutment effect of the abutment portion 421. Under the elastic force of the first elastic member 2233, the magnetic block 2232 and the protrusion 22321 move away from the electromagnet 2231 and reset.

[0072] In some embodiments, the release device 4 also includes a third elastic member 43, a slide rail 44, a mechanical trigger assembly and a stop member 45, one end of the third elastic member 43 is connected to the chassis 3, and the other end is connected to the moving member 42, specifically connected to the abutment 421 of the moving member 42; the slide rail 44 is fixed to the chassis 3, and the slide rail 44 is extended along the moving direction of the push rod 222, and the moving member 42 is slidably assembled on the slide rail 44; the mechanical trigger assembly is installed on the chassis 3, and the stop member 45 is connected to the mechanical trigger assembly, and the stop member 45 has a blocking state of blocking the abutment 421 and a avoiding state of avoiding the abutment 421. By operating the mechanical trigger assembly, the stopper 45 can be driven to switch between the stop state and the avoidance state. When the stopper 45 is in the stop state, the third elastic member 43 is in a stretched or compressed state, and the stopper 45 is in contact with the abutment portion 421, and the stopper 45 stops the abutment portion 421, so that the moving member 42 cannot move freely as a whole. When the stopper 45 is in the avoidance state, the stopper 45 is disconnected from the abutment portion 421, and the stopper 45 avoids the moving path of the moving member 42, so that the moving member 42 can move in the direction close to the transmission shaft 12 under the elastic force of the third elastic member 43. The third elastic member 43 is a compression spring. When the barrier 1 is in normal use, the stopping member 45 is located on the side of the abutment portion 421 close to the transmission shaft 12 and is in a stopping state. The abutment portion 421 remains stationary due to the stopping action of the stopping member 45, and the moving member 42 is in a stationary state. The moving member 42 will not drive the push rod 222 to move, nor will it drive the rotating member 41 to rotate. At this time, the third elastic member 43 is in a compressed state due to the pressing action of the moving member 42. In an emergency situation where the gate rod 11 needs to be opened, the mechanical trigger assembly is operated to switch the stopper 45 from the stop state to the avoidance state, and the stopper 45 no longer stops the abutting portion 421. The abutting portion 421 loses the stopper effect of the stopper 45 and can move freely. Under the elastic action of the third elastic member 43, the moving member 42 and the abutting portion 421 are driven to move in the direction close to the transmission shaft 12. During the movement, the abutting portion 421 abuts against the protrusion 22321 on the magnetic block 2232, driving the push rod 222 to move, releasing the clamping port 212, and driving the transmission shaft 12 to rotate through the moving member 42, driving the gate rod 11 to rotate and open, until the elastic force of the third elastic member 43 is completely released, the gate rod 11 rotates to the highest point, and the emergency opening of the gate rod 11 is completed. Due to the elastic force of the third elastic member 43, the moving member 42 remains stationary, and then the transmission shaft 12 remains stationary, the gate rod 11 remains in the open state and will not reset, thereby improving the stability of the gate rod 11. With the above-mentioned structure, the release device 4 can be operated outside the chassis 3, and the release device 4 is linked with the brake device 2 through mechanical structural components. Even in the case of power failure, the gate rod 11 can be opened smoothly to ensure the smooth passage of vehicles.

[0073] In some embodiments, the moving member 42 is a transmission rack, and the rotating member 41 is a gear ring, and the outer edge teeth of the gear ring can be matched and meshed with the teeth on the transmission rack. The transmission rack is arranged below the gear ring, and when the transmission rack is moved, the gear ring is driven to rotate by the teeth on the transmission rack and the gear ring, thereby driving the transmission shaft 12 to rotate. The meshing of the transmission rack and the gear ring provides a certain restraining force for the transmission shaft 12, and combined with the elastic force of the third elastic member 43, the gate rod 11 is kept in the open state without being reset, further improving the stability of the gate rod 11. The abutment portion 421 is a vertical rod fixed at one end of the moving member 42, and the third elastic member 43 is connected between the vertical rod and the inner wall of the chassis 3. The abutment portion 421 is set to the structural form of a vertical rod, and the vertical rod is perpendicular to the moving member 42. The vertical rod not only plays the role of abutting the protrusion 22321 on the magnetic block 2232, but also facilitates the installation of the third elastic member 43.

[0074] In some embodiments, one end of the stopper 45 is rotatably connected to the slide rail 44, and the stopper 45 has a stop state and an avoidance state in the rotation stroke. The mechanical trigger assembly includes a support frame 47, a pressing rod 46, a first wedge block 461 and a fourth elastic member 48. The support frame 47 is fixed to the inner wall of the chassis 3; the pressing rod 46 is slidably arranged on the side wall of the chassis 3, and one end thereof extends into the support frame 47; the first wedge block 461 is arranged in the support frame 47 and fixed to the end of the pressing rod 46 extending into the support frame 47; one end of the fourth elastic member 48 is connected to the end of the stopper 45 not connected to the slide rail 44, and the other end is fixed with a second wedge block 481 matched with the first wedge block 461, and the second wedge block 481 is movably arranged in the support frame 47 and located on the upper side of the first wedge block 461. When the pressing rod 46 is pressed, the pressing rod 46 drives the first wedge block 461 to move away from the inner wall of the chassis 3, and the first wedge block 461 abuts against the second wedge block 481. Under the cooperation of the inclined surfaces of the two wedge blocks, the first wedge block 461 pushes the second wedge block 481 to move upward, and the first wedge block 461 pushes the second wedge block 481 out of the support frame 47. Since the second wedge block 481 is connected to the fourth elastic member 48, after the second wedge block 481 is pushed out of the support frame 47, the restraining effect of the support frame 47 is lost, so that the fourth elastic member 48 and the second wedge block 481 are released, and the stopping member 45 loses the pulling effect of the fourth elastic member 48 and moves relative to the slide rail 44 to reset, switching from the stopping state to the avoidance state. After the vehicle is released in an emergency, the moving member 42 is reset, and the second wedge block 481 is put back into the support frame 47. The second wedge block 481 is stopped and limited by the support frame 47, so that the stopper 45 is again pulled by the fourth elastic member 48 and switched to the stopped state. The support frame 47 is an L-shaped structure, located above the slide rail 44, the horizontal part of the L-shaped structure is fixed to the inner wall of the chassis 3, and the vertical part of the L-shaped structure plays a stopping and restraining role on the second wedge block 481, so that the stopper 45 can be kept in the stopped state.

[0075] The stopper 45 is in the shape of a rod. One end of the stopper 45 is rotatably connected to one side of the slide rail 44, and the other end of the stopper 45 is connected to the fourth elastic member 48. The fourth elastic member 48 is a tension spring, and the stopper 45 is pulled by the fourth elastic member 48 to cross the slide rail 44, so that the stopper 45 is in a stopped state of stopping the abutting portion 421. After the second wedge block 481 and the fourth elastic member 48 are released, the stopper 45 loses the pulling effect of the fourth elastic member 48, rotates to one side of the slide rail 44 relative to the slide rail 44, and switches the stopper 45 to a avoiding state of avoiding the abutting portion 421, so that the abutting portion 421 can move on the slide rail 44.

[0076] In some embodiments, a fifth elastic member 462 is provided between one end of the pressing rod 46 located outside the chassis 3 and the outer wall of the chassis 3. When the pressing rod 46 is pressed toward the chassis 3, the fifth elastic member 462 is compressed, and the pressing rod 46 is released, so that the pressing rod 46 can be reset under the elastic force of the fifth elastic member 462. The fifth elastic member 462 is a compression spring.

[0077] In some embodiments, the outer wall of the chassis 3 is detachably provided with a protective cover 32, which is provided on the outer periphery of the pressing rod 46. The protective cover 32 protects the pressing rod 46 and prevents the pressing rod 46 from being accidentally touched. The protective cover 32 is a transparent cover body, which is convenient for observing the position of the pressing rod 46. The protective cover 32 and the outer wall of the chassis 3 can be connected by snapping, which is convenient for opening the protective cover 32. The protective cover 32 is made of a transparent acrylic plate.

[0078] The working process of the present invention is:

[0079] When the barrier 1 is in normal use, the access control machine 31 identifies the license plate of the passing vehicle. After the identification is passed, the driving member 13 is started, and at the same time, the electromagnet 2231 is energized to attract the magnetic block 2232 to move close to the electromagnet 2231, and the push rod 222 is driven by the magnetic block 2232 to move toward the transmission shaft 12, and the push rod 222 drives the clamping opening 212 of the clamp assembly 21 to open, releasing the transmission shaft 12, and the transmission shaft 12 is driven to rotate by the driving member 13, driving the gate rod 11 to rotate and open. At this time, the driving member 13 is closed to stop the transmission shaft 12 from rotating, and at the same time, the electromagnet 2231 is powered off, and the magnetic block 2232 drives the push rod 222 to move in the opposite direction and reset under the action of elastic force, and the push rod 222 drives the clamping opening 212 of the clamp assembly 21 to close and clamp on the transmission shaft 12, ensuring that the transmission shaft 12 is locked and fixed, preventing the gate rod 11 from suddenly falling and hitting the vehicle, so that the identified vehicle can pass through the gate rod 11 smoothly. After the vehicle passes the gate rod 11, the driving member 13 is started, and the electromagnet 2231 is energized again to attract the magnetic block 2232 to move close to the electromagnet 2231, and the clamping opening 212 of the clamp assembly 21 is driven to open through the push rod 222, releasing the transmission shaft 12, and the transmission shaft 12 is driven to rotate in the opposite direction through the driving member 13, driving the gate rod 11 to rotate in the opposite direction and close. After the gate rod 11 is fully closed, the driving member 13 is closed to stop the transmission shaft 12 from rotating, and the electromagnet 2231 is powered off. The magnetic block 2232 drives the push rod 222 to move in the opposite direction and reset under the action of elastic force, and the push rod 222 drives the clamping opening 212 of the clamp assembly 21 to close and clamp on the transmission shaft 12, ensuring that the transmission shaft 12 is locked and fixed, and preventing the gate rod 11 from opening under the action of external force.

[0080] In the event of an emergency such as a vehicle colliding with the gate rod 11, the gate rod 11 rotates in a horizontal plane relative to the transmission shaft 12 through the connecting shaft 14 to prevent the gate rod 11 from being broken by the vehicle. When a rescue vehicle such as a fire truck or an ambulance fails to be identified by the access control machine 31 and needs to quickly pass through the gate rod 11, the stopper rod 46 outside the chassis 3 is pressed to switch the stopper rod from the stop state to the avoidance state, so that the moving member 42 moves close to the transmission shaft 12 on the slide rail 44, and at the same time, the push rod 222 is driven to move close to the transmission shaft 12 through the abutment portion 421, and the clamping opening 212 of the clamp assembly 21 is driven to open and release the transmission shaft 12 through the push rod 222, and the rotating member 41 is driven to rotate through the moving member 42, driving the transmission shaft 12 to rotate, so that the gate rod 11 rotates and opens, and the rescue vehicle is released. After releasing the rescue vehicle, the chassis 3 is opened manually, and the moving member 42 is reset by manual external force. After the moving member 42 is reset, the second wedge block 481 is placed in the support frame 47 again to be constrained by the support frame 47, so that the stopper 45 is restored to the stop state. In the process of resetting the moving member 42, the rotating member 41 is driven to rotate in the opposite direction, driving the transmission shaft 12 to rotate in the opposite direction, so that the gate rod 11 rotates and closes. At the same time, the push rod 222 is reset under the elastic force of the first elastic member 2233, so that the clamping opening 212 is closed and clamped on the transmission shaft 12.

[0081] In summary, the embodiment of the present invention provides an intelligent access control system, which is provided with a clamp assembly 21 on one side of the transmission shaft 12, and the clamping opening 212 of the clamp assembly 21 is driven to close or open by the driving assembly 22. The driving assembly 22 is electrically connected to the driving member 13, and when the gate rod 11 needs to rotate, the driving assembly 22 drives the clamping opening 212 to open and release the transmission shaft 12. At the same time, the driving member 13 drives the transmission shaft 12 to rotate, and the gate rod 11 is driven to rotate and open or close through the transmission shaft 12. When the gate rod 11 needs to stop rotating, the driving member 13 stops driving the transmission shaft 12, and the transmission shaft 12 stops rotating due to the loss of the rotational power provided by the driving member 13, so that the gate rod 11 stops at the set fixed position; at the same time, the driving assembly 22 drives the clamping opening 212 to close, and clamps the transmission shaft 12 through the clamp assembly 21, so that the transmission shaft 12 cannot rotate freely due to the constraint of the clamp assembly 21, and then the gate rod 11 cannot rotate freely, so that the gate rod 11 can be stably maintained in the closed state or the open state, thereby preventing the gate rod 11 from rotating and opening under the action of external force when in the closed state or suddenly falling and closing in the open state, thereby improving the safety of the access control system. In addition, by rotating and connecting the gate rod 11 and the transmission shaft 12 through the connecting shaft 14, the gate rod 11 can rotate in a horizontal plane relative to the ground, and when the gate rod 11 is in the closed state, and the vehicle driver does not brake in time or the vehicle suddenly fails, the gate rod 11 can be prevented from being broken by the vehicle. Furthermore, in an emergency situation where a fire truck, an ambulance, etc. needs to quickly pass through the barrier 1, by providing a release device 4 and controlling the release device 4 in conjunction with the brake device 2, the gate rod 11 can be opened in an emergency to release the vehicle.

[0082] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
