Description

Technical Field

[0001] The present invention relates to the technical field of access control, and particularly to an access control device based on multi-sensors. Background Art

[0002] As a core facility for security control, the access control system is widely used in high-security-level places such as airports, venues, and financial institutions. Traditional access control devices mostly adopt mechanical turnstiles or revolving door structures, and achieve access control through single identity authentication (such as swiping cards, fingerprints). However, the existing technologies have the following significant defects:

[0003] Weak anti-tailgating ability: Conventional turnstiles rely on physical intervals to separate people, but cannot effectively detect tailgating or multiple people breaking in parallel. Especially during peak traffic hours, security loopholes are likely to occur.

[0004] Insufficient anti-impact performance: When encountering forced card punching, the traditional mechanical structure lacks a buffer protection mechanism, and is prone to shaft deformation or motor overload.

[0005] Single verification process: Most systems only rely on single identity verification at the entrance, and there are risks of credential fraud or misidentification.

[0006] Contradiction between traffic efficiency and security: The fixed channel width design cannot balance high-traffic access and strict control.

[0007] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and an access control device based on multi-sensors is proposed. Summary of the Invention

[0008] The purpose of the present invention is to provide an access control device based on multi-sensors to solve the problems raised in the above background art.

A first motor is provided at the outer end of the top of the annular passage, and a revolving door component is provided in the middle of the annular passage. The revolving door component includes a rotating rod, a driving rotating ring, a tooth groove, a second motor, a driving gear, a blocking door, a driven rotating ring, a pressure spring, a displacement seat, a thermal infrared sensor, a ranging radar, a sliding seat, and a ball. The outer end of the rotating rod is provided with a driving rotating ring, and a meshing tooth groove is provided inside the driving rotating ring. A second motor is arranged inside the rotating rod, and a driving gear is at the output end of the second motor. The outer end of the driving rotating ring is connected to a blocking door, and the outer end of the blocking door is connected to a driven rotating ring. Pressure springs are provided at both outer ends of the blocking door, and displacement seats are provided at the outer ends of the pressure springs. A thermal infrared sensor is arranged at the outer end of the right part of the displacement seat, and a ranging radar is arranged at the outer end of the left part of the displacement seat. Sliding seats are provided at the upper and lower ends of the displacement seat, and balls are arranged at the upper and lower ends of the displacement seat.

[0010] Further, an access door is provided at the front end of the annular passage, and an exit door is provided at the rear end of the annular passage. An identification component is provided inside the access door and the exit door. A sliding track is provided in the middle of the annular passage, and a magnetic attraction seat is provided inside the sliding track. A pressure sensor is provided at the inner side of the bottom of the annular passage.

[0011] Further, the identification component includes a security inspection door, an identification module, a camera, and an opening and closing door. An identification module is provided at the outer end of the front part of the security inspection door, a camera is arranged at the outer end of the top of the security inspection door, and an opening and closing door is provided at the outer end of the security inspection door.

[0012] Further, the annular passage is circular, and the access door is communicated with the exit door through the annular passage.

[0013] Further, the first motor drives the rotating rod to rotate, and the rotating rod is sleeved and connected with the driving rotating ring.

[0014] Further, the second motor drives the driving gear to rotate, and the driving gear meshes with the tooth groove inside the driving rotating ring.

[0015] Further, the driving rotating ring is welded to the blocking door, and the blocking door is welded to the driven rotating ring.

[0016] Further, the driven rotating ring is sleeved and connected with the rotating rod, and the driving rotating ring drives the driven rotating ring to rotate through the blocking door.

[0017] Further, the blocking door is elastically connected to the displacement seat through the pressure spring, and three groups of blocking doors are provided at the outer end of the driving rotating ring in total.

[0018] Further, the displacement seat slides inside the sliding track through the sliding seat, and the sliding seat is electromagnetically adsorbed and connected to the magnetic adsorption seat.

[0019] The present invention provides an access control device based on multi-sensors, having the following beneficial effects:

[0020] 1. When the identifier reaches the junction of the entrance door and the circular passage by opening or closing the door, the displacement seat synchronously moves to the left side of the opening of the circular passage. The left position of the displacement seat shields to form a right entrance for single-person passage only. Combining the opening direction with the rotation direction of the rotating rod being consistent, it guides the user to enter along the correct path. The ranging radar monitors the user's distance in real time, triggers the second motor to drive the driving gear, and drives the driving rotating ring and the connected blocking door to perform a follow-up circular displacement through the engagement of the tooth grooves, forming a dynamic anti-tailgating barrier. The rotation of the blocking door causes the previous door body to stop at the pressure sensor terminal, ensuring that the user must pass through the pressure detection area. Through the analysis of the pressure application points, the pressure sensor can effectively identify the phenomena of tailgating and multiple people walking side by side. The thermal infrared sensor configured at the left end of the displacement seat simultaneously detects the number of heat sources, forming a dual verification mechanism with the pressure sensor. When the blocking door completes the closed loop, the device can ensure that all personnel are within the effective detection range of the pressure sensor. This collaborative working mode can improve the anti-tailgating detection accuracy and reduce the false alarm rate, and is particularly suitable for the single-person passage control in high-security-level places.

[0021] 2. After the detection of tailgating and multiple people walking side by side is completed, the remaining two groups of blocking doors synchronously rotate to the equally spaced distribution positions along with the driving rotating ring. The first motor then drives the rotating rod to operate in coordination, guiding the user to move along the circular passage to the exit door. The exit door is internally provided with an independent identification component, and the user needs to verify the certificate and ticket for the second time. During this process, the revolving door component locks the passing permission of the rear personnel, realizing single-person sequential release. Through the dual identification mechanism of the entrance door and the exit door, combined with the dynamic blocking door adjustment function of the circular passage, the device can physically separate potential unlicensed tailgaters at the entrance from legitimate users, ensuring no risk of mixed passage during the exit detection. This design enables security personnel to accurately locate abnormal targets, and through the linkage of the pressure sensor, the thermal infrared sensor and the blocking door, form a closed-loop security system from detection, isolation to disposal, and finally realize the efficient control of the false alarm and abnormal handling time limit of the access control system.

[0022] 3. When a forced break-in occurs in the annular channel of the present invention, the magnetic seat in the sliding track positions the sliding seat of the displacement seat through electromagnetic adsorption lock, synchronously freezing the rotational displacement of the barrier door. Its linkage structure is designed by the socket connection of the active rotating ring, the driven rotating ring and the rotating rod, and cooperates with the buffer energy absorption mechanism of the pressure springs on both sides of the barrier door. When bearing an impact, it not only protects the rotating rod from damage, but also avoids overloading of the displacement seat and the track. At the same time, the barrier door on the non-contact side will automatically rotate and fold to compress the activity space of the break-in person. Combining the cooperative displacement ability of the three groups of barrier doors, the system can either form an emergency blockade area or form an unobstructed channel by shifting as a whole when rapid passage is required. This dual mode is dynamically switched by the gear set, taking into account the high security prevention and control and the large flow passage requirements, and realizing the reliable operation of the impact resistance strength and the mode switching time effect.

[0033] Please refer to Figures 1 to 9 , the present invention provides a technical solution: an access control device based on multi-sensors, including a ring-shaped channel 1, an identification component 4 and a revolving door component 6. An entrance door 2 is arranged at the front end of the ring-shaped channel 1, and an exit door 3 is arranged at the rear end of the ring-shaped channel 1. An identification component 4 is arranged inside the entrance door 2 and the exit door 3. A first motor 5 is arranged at the outer end of the top of the ring-shaped channel 1. A sliding track 7 is arranged in the middle of the inside of the ring-shaped channel 1, and a magnetic attraction seat 8 is arranged inside the sliding track 7. A pressure sensor 9 is arranged at the inner side of the bottom of the ring-shaped channel 1. The identification component 4 includes a security inspection door 401, an identification module 402, a camera 403 and an opening and closing door 404. An identification module 402 is arranged at the outer end of the front part of the security inspection door 401, and a camera 403 is arranged at the outer end of the top of the security inspection door 401. An opening and closing door 404 is arranged at the outer end of the security inspection door 401. The ring-shaped channel 1 is circular, and the entrance door 2 is communicated with the exit door 3 through the ring-shaped channel 1;

[0034] The specific operation is as follows. The device is installed at the position of the crossing where documents and tickets are required to pass. During the use of the device, only one person is allowed to pass through a single space separated by the blocking door 606 in the ring-shaped channel 1 at a time. After the device is started, when a person who needs to pass through the access control approaches the security inspection door 401 and brings recognizable items such as documents and tickets close to the identification module 402, the identification module 402 can identify the documents and tickets. At the same time, the camera 403 will identify and record the status of the person using the documents and tickets. After the identification is completed, the opening and closing door 404 is opened, and the person who has completed the identification can pass through the opening and closing door 404 and enter the inside of the ring-shaped channel 1 through the entrance door 2.

[0035] Please refer to Figures 1 to 9, a revolving door assembly 6 is provided at the inner middle end of the annular channel 1. The revolving door assembly 6 includes a rotating rod 601, a driving rotating ring 602, a tooth groove 603, a second motor 604, a driving gear 605, a barrier door 606, a driven rotating ring 607, a pressure spring 608, a displacement seat 609, a thermal infrared sensor 610, a ranging radar 611, a sliding seat 612 and a ball 613. A driving rotating ring 602 is provided at the outer end of the rotating rod 601, and a meshing tooth groove 603 is provided inside the driving rotating ring 602. A second motor 604 is installed inside the rotating rod 601, and a driving gear 605 is provided at the output end of the second motor 604. The outer end of the driving rotating ring 602 is connected to a barrier door 606, and the outer end of the barrier door 606 is connected to a driven rotating ring 607. Pressure springs 608 are provided at both outer ends of the barrier door 606, and a displacement seat 609 is provided at the outer end of the pressure spring 608. A thermal infrared sensor 610 is installed at the outer right end of the displacement seat 609, and a ranging radar 611 is installed at the outer left end of the displacement seat 609. Sliding seats 612 are provided at the upper and lower ends of the displacement seat 609, and balls 613 are installed at the upper and lower ends of the displacement seat 609. The first motor 5 drives the rotating rod 601 to rotate, and the rotating rod 601 is sleeved and connected with the driving rotating ring 602. The second motor 604 drives the driving gear 605 to rotate, and the driving gear 605 meshes with the tooth groove 603 inside the driving rotating ring 602. The driving rotating ring 602 is welded to the barrier door 606, and the barrier door 606 is welded to the driven rotating ring 607. The driven rotating ring 607 is sleeved and connected with the rotating rod 601, and the driving rotating ring 602 drives the driven rotating ring 607 to rotate through the barrier door 606. The barrier door 606 is elastically connected to the displacement seat 609 through the pressure spring 608, and three groups of barrier doors 606 are provided at the outer end of the driving rotating ring 602 in total. The displacement seat 609 slides inside the sliding track 7 through the sliding seat 612, and the sliding seat 612 is electromagnetically adsorbed and connected with the magnetic adsorption seat 8;

[0036] The specific operation is as follows. When the first motor 5 works, it can drive the rotating rod 601 to rotate, which enables the rotating rod 601 to drive the blocking door 606 to perform circumferential displacement inside the annular channel 1. During the displacement of the blocking door 606, it can drive the displacement seat 609 to slide inside the sliding track 7. There are ball bearings 613 at the contact between the displacement seat 609 and the sliding track 7, which can effectively reduce the sliding friction of the displacement seat 609 inside the sliding track 7. When the identifier can pass through the opening and closing door 404 and enter the junction of the entrance door 2 and the annular channel 1, the displacement seat 609 will just move to the left side position of the opening of the annular channel 1 and cover the left channel, which can give a psychological hint to the user to enter the inside of the annular channel 1 along the direction of the rotation of the rotating rod 601 from the right port. This can effectively prevent users who use it for the first time from entering the inside of the annular channel 1 in the reverse direction. In addition, when the displacement seat 609 is at this position, the annular channel 1 will present an opening with only one-person width. After the user enters the inside of the annular channel 1, the ranging radar 611 at the right end of the displacement seat 609 can judge the distance between the displacement seat 609 and the user. At this time, the second motor 604 drives the driving gear 605 to rotate, which can make the driving gear 605 drive the driving rotating ring 602 to rotate through the engagement with the tooth groove 603. Since the driving rotating ring 602 is connected to the blocking door 606, the blocking door 606 at the front end of the annular channel 1 can perform a separate circumferential displacement at this time. With the assistance of the ranging radar 611, the displacement seat 609 can always be close to the user entering the annular channel 1. Through this design, it can effectively prevent people behind from following the user into the inside of the annular channel 1. In addition, the implicit guidance of the displacement seat 609 enables the user to step on the top of the pressure sensor 9 immediately after entering the inside of the annular channel 1. The pressure sensor 9 can sense the pressure application site. By judging the pressure application site, it can effectively detect whether there is a phenomenon of following or multiple people entering the annular compartment of the annular channel 1 at the same time. Since the blocking door 606 at the front end of the annular channel 1 performs a separate circumferential displacement, the previous set of blocking doors 606 will be at the end position of the pressure sensor 9. Through this design, after the annular channel 1 is closed, all people entering the annular channel 1 will be within the detection range of the pressure sensor 9, which can improve the detection accuracy of the pressure sensor 9. In addition, a thermal infrared sensor 610 is provided at the left end of the displacement seat 609. The thermal infrared sensor 610 can judge the number of heat sources within the range. This enables the thermal infrared sensor 610 of the previous set of blocking doors 606 to cooperate with the pressure sensor 9 for double verification, which can improve the detection accuracy of the device. After the detection of following and multiple people walking side by side is completed, the other two sets of blocking doors 606 can rotate with the corresponding driving rotating rings 602 and adjust to the position where the three sets of blocking doors 606 are evenly distributed. After the position adjustment is completed, the first motor 5 drives the rotating rod 601 to rotate, and the users inside the annular channel 1 can enter the exit door 3 along the path of the annular channel 1 as the blocking door 606 displaces. Another set of identification components 4 is installed inside the exit door 3.At this time, after the user brings the certificate and ticket close to the recognition module 402 again, after the recognition module 402 completes the recognition, the opening and closing door 404 opens, and the user can pass through the access control. During the process of the recognition component 4 at the exit door 3 detecting the user, the revolving door component 6 will not release the user behind from the circular passage 1. By adopting the double recognition method, the probability of incorrect access control recognition can be reduced. In addition, when the recognition component 4 at the entrance door 2 is in use, there may be cases where people without certificates or tickets follow or walk side by side. However, through the detection of the circular passage 1, the followers and those walking side by side will be separated from the former, so that there will be no following phenomenon when the recognition component 4 at the exit door 3 detects. And the above design can also enable security personnel to effectively identify followers and those walking side by side, thus greatly improving the security of the access control. In addition, if the followers and those walking side by side in the circular passage 1 find something abnormal and try to force their way through the card, the magnetic seat 8 in the sliding track 7 will perform electromagnetic adsorption on the sliding seat 612 of the displacement seat 609. This makes the displacement seat 609 lock with the sliding track 7, and the rotational displacement of the barrier door 606 will be locked. Since the barrier door 606 is connected to the rotating rod 601 through the active rotating ring 602 and the driven rotating ring 607, and the active rotating ring 602, the driven rotating ring 607 and the rotating rod 601 are sleeved, when the followers and those walking side by side break through the card and push the barrier door 606, it will not cause damage to the rotating rod 601. And a pressure spring 608 is arranged between the barrier door 606 and the displacement seat 609. The pressure spring 608 can effectively absorb the force when the barrier door 606 is pushed, which can avoid damage to the displacement seat 609 and the sliding track 7. During this process, the barrier door 606 on the side not in contact with the card breaker will rotate and move closer to the locked barrier door 606, which can reduce the space where the card breaker is located to prevent it from causing greater damage to the equipment. In addition, the flexible rotation of the active rotating ring 602 driving the barrier door 606 enables the three groups of barrier doors 606 to move closer to the circular passage 1 unidirectionally when there are a large number of people or goods entering and leaving the area inside the access control without the need for access control inspection. This makes an unobstructed passage formed in the circular passage 1 for a large number of people and goods to enter and leave.,

[0037] In summary, for this access control device based on multiple sensors, when in use, first, the device is installed at the crossing position where certificates and tickets are required to pass. And during the use of the device, only one person is allowed to pass through a single space separated by the barrier door 606 in the circular passage 1 at a time. After the device is turned on, the person who needs to pass through the access control approaches the security door 401, and then brings recognizable items such as certificates and tickets close to the recognition module 402. The recognition module 402 can recognize the certificates and tickets. At the same time, the camera 403 will recognize and record the status of the person using the certificates and tickets. After the recognition is completed, the opening and closing door 404 opens, and the person who has completed the recognition can pass through the opening and closing door 404 and enter the inside of the circular passage 1 through the entrance door 2;

[0038] Then, when the first motor 5 operates, it can drive the rotating rod 601 to rotate. This enables the rotating rod 601 to drive the barrier door 606 to perform a circumferential displacement inside the annular channel 1. During the displacement of the barrier door 606, it can drive the displacement seat 609 to slide inside the sliding track 7. There are balls 613 at the contact between the displacement seat 609 and the sliding track 7, which can effectively reduce the sliding friction of the displacement seat 609 inside the sliding track 7. When the identifier can pass through the opening and closing door 404 and enter the junction of the access door 2 and the annular channel 1, the displacement seat 609 will exactly move to the left side position of the opening of the annular channel 1 and cover the left channel. This can give a psychological hint to the user to enter the interior of the annular channel 1 along the direction of the rotation of the rotating rod 601 from the right port, which can effectively prevent users who use it for the first time from entering the interior of the annular channel 1 in the reverse direction;

[0039] Then, when the displacement seat 609 is at this position, it will make the annular channel 1 present a passage opening with only one person's width. And after the user enters the interior of the annular channel 1, the ranging radar 611 at the right end of the displacement seat 609 can judge the distance between the displacement seat 609 and the user. At this time, the second motor 604 drives the driving gear 605 to rotate, which can make the driving gear 605 drive the driving rotating ring 602 to rotate through the engagement with the tooth groove 603. Since the driving rotating ring 602 is connected to the barrier door 606, this enables the barrier door 606 at the front end of the annular channel 1 to perform a separate circumferential displacement. With the assistance of the ranging radar 611, it can make the displacement seat 609 always close to the user entering the annular channel 1. Through this design, it can effectively prevent people behind from following the user into the interior of the annular channel 1. In addition, the implicit guidance of the displacement seat 609 can enable the user to step on the pressure sensor 9 at the first time after entering the interior of the annular channel 1. The pressure sensor 9 can sense the pressing position. By judging the pressing position, it can effectively detect whether there is a phenomenon of following or multiple people entering the annular compartment of the annular channel 1 at the same time. Since the barrier door 606 at the front end of the annular channel 1 performs a separate circumferential displacement, the previous set of barrier doors 606 will be at the end position of the pressure sensor 9 at this time. Through this design, after the annular channel 1 is closed, all people entering the annular channel 1 will be within the detection range of the pressure sensor 9, which can improve the detection accuracy of the pressure sensor 9. In addition, a thermal infrared sensor 610 is provided at the left end of the displacement seat 609, and the thermal infrared sensor 610 can judge the number of heat sources within the range. This enables the thermal infrared sensor 610 of the previous set of barrier doors 606 to cooperate with the pressure sensor 9 for double verification, which can improve the detection accuracy of the device;

[0040] Subsequently, after the detection of trailing and multi-person parallel walking is completed, the other two groups of barrier gates 606 can rotate with the active rotating rings 602 at the corresponding positions and be adjusted to the positions where the three groups of barrier gates 606 are evenly distributed. After the position adjustment is completed, the first motor 5 drives the rotating rod 601 to rotate, and the users in the annular channel 1 can enter the interior of the exit door 3 along the path of the annular channel 1 with the displacement of the barrier gate 606. Another group of identification components 4 are arranged inside the exit door 3. At this time, when the user brings the certificate and ticket close to the identification module 402 again, after the identification module 402 completes the identification, the opening and closing door 404 opens, and the user can pass through the access control. During the process of the user being detected by the identification component 4 of the exit door 3, the revolving door component 6 will not release the users behind from the annular channel 1. By adopting the double-identification method, the probability of incorrect access control identification can be reduced. In addition, when the identification component 4 at the entrance door 2 is in use, there may be cases where people without certificates or tickets trail or walk in parallel. However, through the detection in the annular channel 1, the trailing and parallel walkers will be separated from the former, which makes it impossible for there to be a trailing phenomenon when the identification component 4 at the exit door 3 conducts the detection. And the above design can also enable the security personnel to effectively identify the trailing and parallel walkers, thus greatly improving the security of the access control;

[0041] Finally, if the trailing and parallel walkers in the annular channel 1 find something abnormal and attempt to force their way through the card, the magnetic seat 8 in the sliding track 7 will electromagnetically adsorb the sliding seat 612 of the displacement seat 609. This causes the displacement seat 609 to be locked with the sliding track 7, which locks the rotational displacement of the barrier gate 606. Since the barrier gate 606 is connected to the rotating rod 601 through the active rotating ring 602 and the driven rotating ring 607, and the active rotating ring 602, the driven rotating ring 607 and the rotating rod 601 are sleeved, when the trailing and parallel walkers force their way through the card and push the barrier gate 606, it will not cause damage to the rotating rod 601. A pressure spring 608 is arranged between the barrier gate 606 and the displacement seat 609, and the pressure spring 608 can effectively absorb the force when the barrier gate 606 is pushed, which can prevent damage to the displacement seat 609 and the sliding track 7. During this process, the barrier gate 606 on the side not in contact with the card rusher will rotate and move closer to the locked barrier gate 606, which can reduce the space where the card rusher is located to prevent them from causing greater damage to the equipment. In addition, the active rotating ring 602 drives the barrier gate 606 to rotate flexibly. When there are a large number of people who do not need access control inspection or goods enter and exit the area inside the access control, the three groups of barrier gates 606 can move unidirectionally closer to the annular channel 1, forming an unobstructed channel in the annular channel 1 to facilitate the entry and exit of a large number of people and goods.
