Description

Technical Field

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

[0002] Access control systems are the core facilities for security control and are widely used in high-security places such as airports, stadiums, and financial institutions. Traditional access control devices mostly use mechanical gates or revolving door structures to achieve access control through a single identity authentication (such as card swiping, fingerprint). However, the existing technology has the following significant defects: Weak anti-tailgating capability: Conventional gates rely on physical separation to separate people, but cannot effectively detect tailgating or multiple people entering at the same time, which is prone to security loopholes, especially during busy traffic hours; Insufficient impact resistance: When encountering a forced entry, the traditional mechanical structure lacks a buffer protection mechanism, which can easily cause the shaft to deform or the motor to overload; Simplified verification process: Most systems rely on a single identity verification at the entrance, which may lead to the risk of credential fraud or misidentification. Conflict between traffic efficiency and safety: The fixed channel width design cannot take into account both large-volume traffic and strict control.

[0003] Therefore, in view of this, the existing structure and deficiencies are studied and improved, and a multi-sensor based access control device is proposed. Summary of the invention

[0004] The object of the present invention is to provide a multi-sensor based access control device to solve the problems raised in the above background technology.

[0006] Furthermore, an entry door is provided at the front end of the annular channel, and an exit door is provided at the rear end of the annular channel, identification components are provided inside the entry door and the exit door, a sliding track is provided at the middle end of the inner part of the annular channel, and a magnetic suction seat is provided inside the sliding track, and a pressure sensor is provided on the inner side of the bottom of the annular channel.

[0007] Furthermore, the identification component includes a security door, an identification module, a camera and an opening and closing door. The front outer end of the security door is provided with an identification module, and the top outer end of the security door is provided with a camera. The outer end of the security door is provided with an opening and closing door.

[0008] Furthermore, the annular channel is in a circular ring shape, and the entrance door is connected with the exit door through the annular channel.

[0009] Furthermore, the first motor drives the rotating rod to rotate, and the rotating rod is sleeve-connected with the active rotating ring.

[0010] Furthermore, the second motor drives the driving gear to rotate, and the driving gear is meshed with the tooth groove inside the driving rotating ring.

[0011] Furthermore, the active swivel is connected to the barrier door by welding, and the barrier door is connected to the driven swivel by welding.

[0012] Furthermore, the driven rotating ring is sleeve-connected with the rotating rod, and the active rotating ring drives the driven rotating ring to rotate through the blocking door.

[0013] Furthermore, the barrier door is elastically connected to the displacement seat through a pressure spring, and three groups of barrier doors are arranged at the outer end of the active swivel.

[0014] Furthermore, the displacement seat slides inside the sliding track through the sliding seat, and the sliding seat is connected to the magnetic seat by electromagnetic adsorption.

[0015] The present invention provides a multi-sensor access control device, which has the following beneficial effects: 1. When the identifier reaches the junction of the entrance door and the annular passage through the opening and closing door, the displacement seat synchronously moves to the left side of the annular passage opening, and the left position of the displacement seat shields the right entrance for only one person to pass through. Combined with the opening direction being consistent with the rotation direction of the rotating rod, the user is guided to enter along the correct path, and the ranging radar monitors the user's distance in real time, triggers the second motor to drive the active gear, and drives the active rotating ring and the connected barrier door to perform follow-up circular displacement through tooth-slot engagement to form a dynamic anti-tailgating barrier. The rotation of the barrier door causes the preceding door body to stop at the pressure sensor terminal to ensure that the user must pass through the pressure detection area. The pressure sensor can effectively identify tailgating and multi-person parallel phenomena through pressure site analysis. The thermal infrared sensor configured at the left end of the displacement seat synchronously detects the number of heat sources, forming a double verification mechanism with the pressure sensor. When the barrier door completes the closed loop, the equipment 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 single-person passage control in high-security places.

[0016] 2. After the present invention completes the tailgating and multi-person parallel detection, the remaining two groups of barrier doors rotate synchronously with the active rotating ring to equidistant distribution positions, and the first motor then drives the rotating rod to operate in coordination to guide the user to move along the circular channel to the exit door. The exit door has a built-in independent identification component, and the user needs to verify the certificate and ticket twice. During this process, the turnstile component will lock the access rights of the rear personnel and realize the release of a single person in sequence. Through the dual identification mechanism of the entrance door and the exit door, combined with the dynamic barrier door adjustment function of the circular channel, the equipment can physically separate potential unlicensed tailgaters from legal users at the entrance to ensure that there is no risk of mixing during exit detection. This design enables security personnel to accurately locate abnormal targets, and through the linkage of pressure sensors, thermal infrared sensors and barrier doors, a closed-loop security system from detection, isolation to disposal is formed, ultimately achieving efficient control of false alarms of the access control system and the timeliness of abnormal processing.

[0017] 3. In the present invention, when a person forcibly breaks into the annular channel, the magnetic seat in the sliding track locks the sliding seat of the displacement seat through electromagnetic adsorption, and simultaneously freezes the rotational displacement of the barrier door. The linkage structure is designed through the sleeve connection of the active swivel, the driven swivel and the rotating rod, and cooperates with the buffering energy absorption mechanism of the pressure springs on both sides of the barrier door. When subjected to 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 close to compress the activity space of the person who breaks into the card. Combined with the coordinated displacement capabilities of the three groups of barrier doors, the system can form an emergency blockade area, and can also shift sideways as a whole to form an unobstructed channel when quick passage is required. The dual mode is dynamically switched through the gear set, taking into account both high-security prevention and control and large-volume traffic requirements, and achieving reliable operation of impact resistance and mode switching time.

After the recognition is completed, the opening and closing door 404 is opened, and the person who has completed the recognition can pass through the opening and closing door 404 and enter the interior of the circular channel 1 through the entry door 2.

[0021] See also Figures 1 to 9The inner middle end of the annular channel 1 is provided with a revolving door assembly 6, which includes a rotating rod 601, an active rotating ring 602, a tooth groove 603, a second motor 604, a driving gear 605, a blocking 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. The outer end of the rotating rod 601 is provided with an active rotating ring 602, and the inner part of the active rotating ring 602 is provided with a meshing gear. The second motor 604 is arranged inside the rotating rod 601, and the output end of the second motor 604 is provided with a driving gear 605, the outer end of the driving rotating ring 602 is connected with a blocking door 606, and the outer end of the blocking door 606 is connected with a driven rotating ring 607, and the outer ends of the blocking door 606 are provided with pressure springs 608, and the outer end of the pressure spring 608 is provided with a displacement seat 609, and the right outer end of the displacement seat 609 is provided with a thermal infrared sensor 610, and the displacement seat 609 The left outer end of the displacement seat 609 is provided with a ranging radar 611, the upper and lower ends of the displacement seat 609 are provided with sliding seats 612, and the upper and lower ends of the displacement seat 609 are provided with ball bearings 613, the first motor 5 drives the rotating rod 601 to rotate, and the rotating rod 601 is sleeve-connected with the active rotating ring 602, the second motor 604 drives the active gear 605 to rotate, and the active gear 605 is meshed with the tooth groove 603 inside the active rotating ring 602, the active rotating ring 602 is welded to the blocking door 606, and the blocking door 606 is welded to the blocking door 606. The partition door 606 is welded to the driven rotating ring 607, the driven rotating ring 607 is sleeved to the rotating rod 601, and the active 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 the barrier door 606 is provided with three groups at the outer end of the active rotating ring 602, 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 to the magnetic seat 8; The specific operation is as follows: the first motor 5 works to drive the rotating rod 601 to rotate, so that the rotating rod 601 can drive the blocking door 606 to move in a circular manner inside the annular channel 1, and the blocking door 606 can drive the displacement seat 609 to slide and move inside the sliding track 7 during the displacement process. The contact between the displacement seat 609 and the sliding track 7 is provided with a ball 613, which can effectively reduce the sliding friction of the displacement seat 609 inside the sliding track 7. When the person who completes the identification can pass through the opening and closing door 404 and enter the junction of the entry door 2 and the annular channel 1, the displacement seat 609 will just move to the left side of the opening of the annular channel 1 and cover the channel on the left side, which can give the user a psychological hint that the user can move from the right end of the opening along the direction of rotation of the rotating rod 601 to the annular channel 1. This can effectively prevent the first-time user from entering the annular channel 1 in reverse. In addition, when the displacement seat 609 is located at this position, the annular channel 1 will present an opening with a width of only one person. After the user enters the annular channel 1, the distance-finding radar 611 at the right end of the displacement seat 609 can determine the distance between the displacement seat 609 and the user. At this time, the second motor 604 drives the active gear 605 to rotate, and the active gear 605 can drive the active rotating ring 602 to rotate by engaging with the tooth groove 603. Because the active rotating ring 602 is connected to the blocking door 606, the blocking door 606 located at the front end of the annular channel 1 can perform a separate circumferential displacement. With the assistance of the distance-finding radar 611, the displacement seat 609 can always be close to entering the annular channel. 1, through this design, it can effectively prevent the rear personnel from following the user into the annular channel 1. In addition, the implicit guidance of the displacement seat 609 can make the user step on the top of the pressure sensor 9 as soon as possible after entering the annular channel 1. The pressure sensor 9 can sense the pressure-applied position. By judging the pressure-applied position, it can effectively detect whether there is a phenomenon of following or multiple people entering the compartment of the annular channel 1 at the same time. Because the barrier door 606 located at the front end of the annular channel 1 performs a separate circumferential displacement, the barrier door 606 of the previous group will be located 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 are 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 arranged at the left end of the displacement seat 609. The thermal infrared sensor 610 can judge the number of heat sources within the range, so that the thermal infrared sensor 610 of the upper group of barrier doors 606 can cooperate with the pressure sensor 9 for double verification, which improves the detection accuracy of the equipment. After completing the detection of tailgating and multi-person parallel, the remaining two groups of barrier doors 606 can rotate with the active rotating ring 602 at the corresponding position and adjust to the position where the three groups of barrier doors 606 are equidistantly distributed. After completing the position adjustment, the first motor 5 drives the rotating rod 601 to rotate, and the user in the annular channel 1 can enter the exit door 3 along the path of the annular channel 1 with the displacement of the barrier door 606. Another group of identification components 4 is arranged inside the exit door 3.At this time, after the user brings the ID and ticket close to the identification module 402 again, the identification module 402 completes the identification, and the opening and closing door 404 opens, and the user can pass through the access control. During the detection of the identification component 4 of the user at the exit door 3, the turnstile component 6 will not let the user behind leave the annular channel 1. By adopting the double identification method, the probability of access control recognition errors can be reduced. In addition, when the identification component 4 at the entrance door 2 is used, there may be a situation where a person without an ID or ticket follows or runs parallel, but after the detection of the annular channel 1, the following and running parallel will be separated from the former, so that the following phenomenon will not occur when the identification component 4 at the exit door 3 detects, and the above design can also enable security personnel to effectively identify the following and running parallel, thereby greatly improving the security of the access control. In addition, if the following and running parallel in the annular channel 1 find an abnormality and try to force the card, the magnetic seat 8 in the sliding track 7 will electromagnetically absorb the sliding seat 612 of the displacement seat 609, so that the displacement seat 609 will be locked with the sliding track 7, which makes the blocking door 606 The rotation displacement will be locked, and because the blocking 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 and the driven rotating ring 607 are sleeved with the rotating rod 601, this makes it possible for the trailing and parallel people to break through the card and push the blocking door 606 without causing damage to the rotating rod 601, and a pressure spring 608 is arranged between the blocking door 606 and the displacement seat 609, and the pressure spring 608 can effectively absorb the force when the blocking door 606 is pushed, which can avoid damage to the displacement seat 609 and the sliding rail. In this process, the barrier door 606 on the side not in contact with the card intruder will rotate and move closer to the locked barrier door 606, which can reduce the space where the card intruder is located to prevent him from causing greater damage to the equipment. In addition, the active swivel 602 drives the flexible rotation of the barrier door 606. When there are a large number of people who do not need access control inspection or goods entering and leaving the access control area, the three groups of barrier doors 606 can move closer to the annular channel 1 in one direction, so that an unobstructed channel can be formed in the annular channel 1 to facilitate the entry and exit of a large number of people and goods.

[0022] In summary, when the multi-sensor-based access control device is used, the device is first deployed at the crossing position where the ID card and ticket are required to pass through, and during the use of the device, the single space separated by the barrier door 606 in the annular channel 1 only allows one person to pass through at a time. After the device is turned on, the person who needs to pass the access control approaches the security door 401, and brings the ID card, ticket and other identifiable items close to the recognition module 402. The recognition module 402 can recognize the ID card and ticket, and the camera 403 will recognize and record the status of the person using the ID card and ticket. After the recognition is completed, the opening and closing door 404 is opened, and the person who has completed the recognition can pass through the opening and closing door 404 and enter the interior of the annular channel 1 through the entry door 2; Then, the first motor 5 works to drive the rotating rod 601 to rotate, so that the rotating rod 601 can drive the barrier door 606 to move in a circular manner inside the annular channel 1. During the displacement process, the barrier door 606 can drive the displacement seat 609 to slide and move inside the sliding track 7. The contact between the displacement seat 609 and the sliding track 7 is provided with a ball 613, which can effectively reduce the sliding friction of the displacement seat 609 inside the sliding track 7. When the person who has completed the identification can pass through the opening and closing door 404 and enter the junction of the entry door 2 and the annular channel 1, the displacement seat 609 will just move to the left side of the opening of the annular channel 1 and cover the channel on the left side, which can give the user a psychological hint that the user can enter the inside of the annular channel 1 from the right end along the direction of rotation of the rotating rod 601, which can effectively prevent the first-time user from entering the inside of the annular channel 1 in reverse. Then, when the displacement seat 609 is located at this position, the annular channel 1 will present an opening with a width of only one person, and after the user enters the annular channel 1, the distance-finding radar 611 at the right end of the displacement seat 609 can determine the distance between the displacement seat 609 and the user. At this time, the second motor 604 drives the active gear 605 to rotate, and the active gear 605 can drive the active swivel 602 to rotate by engaging with the tooth groove 603. Because the active swivel 602 is connected with the barrier door 606, the barrier door 606 located at the front end of the annular channel 1 can perform a separate circular displacement. With the assistance of the distance-finding 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 the rear personnel from following the user into the annular channel 1. In addition, the implicit guidance of the displacement seat 609 can enable the user to enter the annular channel 1. Step on the top of the pressure sensor 9 as soon as possible. The pressure sensor 9 can sense the position of pressure application. By judging the position of pressure application, it can effectively detect whether there is a phenomenon of following or multiple people entering the compartment of the annular channel 1 at the same time. Because the barrier door 606 located at the front end of the annular channel 1 performs a separate circumferential displacement, the barrier door 606 of the previous group will be located 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 are located 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, which enables the thermal infrared sensor 610 of the previous group of barrier doors 606 to cooperate with the pressure sensor 9 for double verification, which improves the detection accuracy of the equipment. After the detection of tailgating and multiple people in parallel is completed, the remaining two groups of barrier doors 606 can rotate with the active rotating ring 602 at the corresponding position and adjust to the position where the three groups of barrier doors 606 are equidistantly distributed. After the position adjustment is completed, the first motor 5 drives the rotating rod 601 to rotate, and the user in the annular channel 1 can enter the exit door 3 along the path of the annular channel 1 along the displacement of the barrier door 606. Another group 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 identification module 402 again, the identification module 402 completes the identification, and the opening and closing door 404 opens, and the user can pass through the access control , and during the detection of the user at the exit door 3 by the identification component 4, the turnstile component 6 will not let the user behind leave the circular passage 1. By adopting the double identification method, the probability of access control recognition errors can be reduced. In addition, when the identification component 4 at the entry door 2 is used, there may be a situation where a person without a certificate or ticket follows or runs parallel, but after the detection of the circular passage 1, the person who follows and runs parallel will be separated from the former, so that the phenomenon of following will not occur when the identification component 4 at the exit door 3 detects. The above design can also enable security personnel to effectively identify the person who follows and runs parallel, thereby greatly improving the security of the access control; Finally, if the trailing and parallel travelers in the annular channel 1 find an abnormality and try to force their way through the card, the magnetic seat 8 in the sliding track 7 will electromagnetically absorb the sliding seat 612 of the displacement seat 609, so that the displacement seat 609 will be locked with the sliding track 7, which will lock the rotation displacement of the blocking door 606. Since the blocking 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 and the driven rotating ring 607 are sleeved with the rotating rod 601, when the trailing and parallel travelers push the blocking door 606 to break through the card, it will not cause damage to the rotating rod 601. A pressure barrier is set between the blocking 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 that is not in contact with the card intruder will rotate and move closer to the locked barrier door 606, which can reduce the space where the card intruder is located to prevent him from causing greater damage to the equipment. In addition, the active swivel 602 drives the flexible rotation of the barrier door 606. When there are a large number of people who do not need access control inspection or when there are goods entering and leaving the access control area, the three groups of barrier doors 606 can be displaced toward the annular channel 1 in one direction, which enables an unobstructed channel to be formed in the annular channel 1 to facilitate the entry and exit of a large number of people and goods.
