Description

Technical Field

[0001] The present invention belongs to the technical field of access control management, and particularly relates to a security alarm device for access control management. Background Technique

[0002] Access control systems are applicable to various confidential departments, such as banks, hotels, parking lot management, computer rooms, armories, confidential rooms, offices, intelligent communities, factories, etc. The access control systems in these places can identify registered personnel and let them pass, while rejecting unregistered personnel from entering.

[0003] The access control management system can control the entry and exit of personnel, and can also control the behavior of personnel in the building and sensitive areas and accurately record and statistically manage digital access control system data. It mainly solves the security problems of important places such as enterprises, institutions, schools, communities, offices, etc.; the existing network access control management system consists of access control devices, access control cards, card readers, access control management hosts, and access control management software, etc.; when in use, it needs to control the card reader to read the information stored in the access control card for identification, and after successful identification, control the access control device to open, and at this time, passage is allowed; however, in actual use, there is a situation where an access control card can be used to pass through the access control device infinitely many times, which has a certain impact on the actual access control security management. Summary of the Invention

[0004] The purpose of the present invention is to provide a security alarm device for access control management. Through the real-time data migration between database A and database B, accurate tracking of the entry and exit status of personnel is realized, preventing permission replication, and avoiding the use of an access control card to pass through the access control device infinitely many times, thus solving the problems raised in the existing background technique.

[0005] To solve the above technical problems, the present invention is realized through the following technical solutions:

[0006] The present invention is a security alarm device for access control management, including at least three turnstile main bodies. A passage is formed between two adjacent turnstile main bodies. A turnstile door assembly located in the passage is installed on the turnstile main body. An entry identity recognition component and an exit identity recognition component are provided on the turnstile main body on one side of any passage. Both the entry identity recognition component and the exit identity recognition component are connected to a turnstile controller, and the turnstile controller is connected to the turnstile door assembly and an alarm component;

[0007] A security alarm method for access control management includes:

[0008] Step 1: After the entry identity recognition component recognizes and obtains the identity information, determine whether the identity information exists in database A. If so, the turnstile door assembly is opened and step 2 is entered; otherwise, the alarm component performs a primary alarm action;

[0009] Step 2: When it is detected that a person passes through the passage, move the identity information in Step 1 from Database A to Database B, and close the turnstile door assembly.

[0010] Step 3: After the exit identity recognition component obtains the identity information, determine whether the identity information exists in Database B. If so, open the turnstile door assembly and proceed to Step 4; otherwise, the alarm component performs a first-level alarm action.

[0011] Step 4: When it is detected that a person passes through the passage, move the identity information in Step 3 from Database B to Database A, and close the turnstile door assembly.

[0012] Furthermore, the turnstile door assembly includes a power component, a rotating shaft, and a modular door.

[0013] The power component is arranged inside the turnstile main body and drives the rotating shaft to rotate, and the modular door is installed on the rotating shaft.

[0014] Furthermore, the entrance identity recognition component and the exit identity recognition component have the same structure, and both include a face capture camera and a sensing device. The sensing device is an NFC sensing device or a radio frequency identification sensing device; the identity information includes the first information collected by the sensing device and the second information collected by the face capture camera.

[0015] In Step 1, when the sensing device detects the first information, determine whether the first information is stored in Database A. If so, collect the second information through the face capture camera and associate it with the first information to form the identity information and store it in Database A; otherwise, give an alarm and collect the second information through the face capture camera and store it in Database C.

[0016] In Step 3, when the sensing device detects the first information, determine whether the first information is stored in Database B. If so, collect the second information through the face capture camera and determine whether the second information is stored in Database B.

[0017] When it is determined that the second information is stored in Database B, at this time, control the turnstile door assembly to open; otherwise, the alarm component performs a first-level alarm action.

[0018] When the first information is not stored in Database B, at this time, the alarm component performs a first-level alarm action.

[0019] In Step 4, when it is detected that a person passes through the passage, after permanently deleting the second information from the identity information, move the identity information in Step 3 from Database B to Database A.

[0020] Further, in step 3, when the person does not carry the identification plate that matches the induction device for identification and the turnstile door assembly needs to be controlled to open; at this time, the second information is first collected by the face collection camera corresponding to one channel, and then the second information is collected by any other face collection camera corresponding to a channel within a continuous time period of T. When it is determined that the second information collected twice is the same and stored in database B, the turnstile door assembly is opened at this time, and the alarm component performs a secondary alarm action; then in step 4, the identity information including the second information in step 3 is moved from database B to database A.

[0021] Further, in step 1, when the person does not carry the identification plate that matches the induction device for identification and the turnstile door assembly needs to be controlled to open; at this time, the face collection camera collects the second information. When it is determined that the collected second information is stored in database A, the turnstile door assembly is opened at this time, and the alarm component performs a secondary alarm action; otherwise, the alarm component performs a primary alarm action; then in step 2, the identity information including the second information in step 1 is moved from database A to database B.

[0022] Further, it also includes a passage detection unit for detecting whether there is a person passing through the passage, and the passage detection unit is connected to the turnstile controller; the passage detection unit includes two groups of passage detection modules; the two groups of passage detection modules are respectively arranged at both ends of the passage; the passage detection module includes an infrared emission module and an infrared reception module arranged opposite to each other.

[0023] Further, two installation cavities are opened on the side walls of the turnstile main body on both sides of the passage, and an infrared emission module or an infrared reception module is installed in any one of the installation cavities.

[0024] Further, the infrared emission module or the infrared reception module is respectively connected to the power supply through a power supply circuit for telecommunication, and a switch module for controlling its on-off is arranged on the power supply circuit; a driving structure for driving the switch module to switch is arranged on the rotating shaft; the switch module includes a mutually cooperating inner sleeve and outer sleeve, and fixing rings A and B are arranged on the inner wall of the inner sleeve; a first spring is connected between the fixing ring A and the outer sleeve; the upper surface of the fixing ring B is connected to a movable plate through a second spring, a first conductor is fixed on the bottom side of the movable plate, and a second conductor is arranged in the inner sleeve; a push rod for driving the movable plate to move is arranged on the inner top side of the outer sleeve;

[0025] When the turnstile door assembly is controlled to open, at this time the rotating shaft rotates, and then under the action of the driving structure, the outer sleeve is driven to move towards the inner sleeve side.

[0026] Further, the first conductor includes a first ceramic sleeve, and a first conductive column connected to a first wire is fixed inside the first ceramic sleeve; the second conductor includes a second ceramic sleeve, and a second conductive column connected to a second wire is fixed inside the second ceramic sleeve; an arc protection sleeve sleeving the outside of the second ceramic sleeve is fixed at the end of the first ceramic sleeve; the bottom side of the inner sleeve is connected to a mounting plate through a third spring, and the second ceramic sleeve is fixed on the mounting plate; both the first wire and the second wire penetrate and are fixed on the mounting plate and the inner sleeve.

[0027] Further, the driving structure includes a ring fixed on the rotating shaft, and two symmetrically arranged driving parts are provided on the outer side wall of the ring; extending from the middle of the driving part to both sides, the distance between the outer wall surface of the driving part and the inner wall surface of the ring gradually decreases.

[0028] The present invention has the following beneficial effects:

[0029] Through the real-time data migration of database A and database B, the present invention realizes the accurate tracking of the entry and exit status of personnel, prevents permission replication, avoids using one access control card to achieve unlimited access to access control devices, and forcibly associates NFC recognition with face information to ensure "one person, one card, one face", eliminating the risk of misappropriation.

[0030] Of course, it is not necessary for any product implementing the present invention to simultaneously achieve all the above-mentioned advantages. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] Embodiment 1

[0044] Please refer to Figure 1As shown in the figure, the present invention is a security alarm device for access control management, including three turnstile bodies 1 arranged in parallel with gaps, and a passage for personnel to pass through is formed between adjacent turnstile bodies 1. A gate mechanism for managing the passage through the passage is arranged in the passage. The gate mechanism includes two turnstile door assemblies respectively installed on the turnstile bodies 1 on both sides of the passage, and an entrance identity recognition assembly and an exit identity recognition assembly for controlling the opening of the turnstile door assemblies in the corresponding passage are arranged on the turnstile bodies 1. The entrance identity recognition assembly and the exit identity recognition assembly are both connected to the turnstile controller, and the turnstile controller is connected to the turnstile door assemblies. Furthermore, when in use, after the identity recognition is completed through the entrance identity recognition assembly and the exit identity recognition assembly, the turnstile door assemblies are controlled to open, and the turnstile door assemblies are closed after the personnel pass through the passage.

[0045] Specifically, the turnstile door assembly provided by the present invention includes a rotating shaft 10 power assembly arranged in the turnstile body 1, and a rotating shaft 10 connected to the power assembly and rotating under the drive of the power assembly. A module door 11 is installed on the rotating shaft 10. Furthermore, when in use, when controlling the turnstile door assembly to open, the rotating shaft 10 is controlled to rotate 90°; that is, when entering or exiting, the module door 11 is controlled to rotate 90° away from the personnel side.

[0046] As Figure 6 , based on the above settings, the security alarm method for access control management includes:

[0047] Step 1: After the entrance identity recognition assembly recognizes and obtains the identity information, it is judged whether the identity information exists in database A. If so, the turnstile door assembly is opened and step 2 is entered; otherwise, the alarm assembly performs a first-level alarm action.

[0048] Step 2: When it is detected that the personnel pass through the passage, the identity information in step 1 is moved from database A to database B, and the turnstile door assembly is closed.

[0049] Step 3: After the exit identity recognition assembly recognizes and obtains the identity information, it is judged whether the identity information exists in database B. If so, the turnstile door assembly is opened and step 4 is entered; otherwise, the alarm assembly performs a first-level alarm action.

[0050] Step 4: When it is detected that the personnel pass through the passage, the identity information in step 3 is moved from database B to database A, and the turnstile door assembly is closed.

[0051] Embodiment 2

[0052] Based on Embodiment 1, the entrance identity recognition component and the exit identity recognition component provided by the present invention have the same composition, both including a face collection camera 12 and a sensing device 13, and the sensing device 13 is an NFC sensing device. The identity information includes the first information collected by the sensing device 13 and the second information collected by the face collection camera 12.

[0053] Based on the settings of the face collection camera 12 and the sensing device 13, a security alarm method for access control management includes:

[0054] Step 1: Collect entry information through the entrance identity recognition component: When the sensing device 13 detects the first information, determine whether the first information is stored in Database A. If so, collect the second information through the face collection camera 12 and associate it with the first information to form identity information and store it in Database A; otherwise, give an alarm and collect the second information through the face collection camera 12 and store it in Database C.

[0055] Step 2: When it is detected that a person passes through the passage, move the identity information in Step 1 from Database A to Database B and close the gate component.

[0056] Step 3: Collect exit information through the exit identity recognition component: When the sensing device 13 detects the first information, determine whether the first information is stored in Database B. If so, collect the second information through the face collection camera 12 and determine whether the second information is stored in Database B.

[0057] When it is determined that the second information is stored in Database B, at this time, control the gate component to open; otherwise, the alarm component performs a first-level alarm action.

[0058] When the first information is not stored in Database B, at this time, the alarm component performs a first-level alarm action.

[0059] Step 4: When it is detected that a person passes through the passage, after permanently deleting the second information from the identity information, move the identity information in Step 3 from Database B to Database A.

[0060] It can be known that in Step 3 above, when it is necessary to control the gate component to open for going out, if the person does not carry an identification card that cooperates with the sensing device 13 at this time, then the person can collect the second information for the first time through the face collection camera 12 corresponding to one passage, and then collect the second information for the second time through the face collection camera 12 corresponding to any other passage within 20 seconds. Analyze the second information collected twice. When it is judged that they are the same and stored in Database B, at this time, open the gate component and the alarm component performs a second-level alarm action; then in Step 4, move the identity information including the second information in Step 3 from Database B to Database A.

[0061] When the person does not carry the identification plate for identification in cooperation with the induction device 13 and completes passing through the turnstile by collecting the second information twice as described above, when the person needs to pass through the turnstile again to enter, at this time, the face collection camera 12 collects the second information. When it is determined that the collected second information is stored in database A, the turnstile door assembly is opened at this time, and the alarm assembly performs a secondary alarm action; otherwise, the alarm assembly performs a primary alarm action; then, in step 2, the identity information including the second information in step 1 is moved from database A to database B.

[0062] Embodiment 3

[0063] Based on Embodiment 2, when the present invention is in use, a passage detection unit for detecting whether there is a person passing through the passage is further provided in any passage, and the passage detection unit is connected to the turnstile controller; through the setting of the passage detection unit, after the identity recognition is completed by the entry identity recognition component or the exit identity recognition component, the turnstile door assembly is controlled to open, and the turnstile door assembly is closed after the person passes through the passage, avoiding the situation that multiple people pass through when the turnstile door assembly is controlled to open once.

[0064] Specifically, the passage detection unit includes two groups of passage detection modules; the two groups of passage detection modules are respectively arranged at both ends of the passage, and the passage detection module includes an infrared emission module and an infrared reception module arranged opposite to each other; when a person passes through the passage, when the leg / waist / hip position of the person passes through the light path of the infrared light emitted by the infrared emission module and the infrared reception module, the light path of the infrared light emitted by the infrared emission module is blocked at this time, indicating that a person has passed through; when both passage detection modules detect that a person has passed through, it is determined that the person has passed through the passage.

[0065] Embodiment 4, on the basis of Embodiment 3, in order to facilitate the control of the activation of the infrared emission module and the infrared reception module, the infrared emission module or the infrared reception module provided by the present invention is respectively connected to the power supply through a power supply circuit, and a switch module 2 for controlling its on / off is arranged on the power supply circuit, and a driving structure 3 for driving the switch module 2 to switch is arranged on the rotating shaft 10; further, when the turnstile door assembly is controlled to open, at this time, the rotating shaft 10 rotates, and at this time, under the action of the driving structure 3, the switch module 2 is driven to close, and the power supply circuit is turned on; conversely, when the turnstile door assembly is controlled to close, at this time, the rotating shaft 10 rotates, and at this time, the switch module 2 is opened under its own action, and the power supply circuit is disconnected.

[0066] Specifically, as Figure 2, the switch module 2 includes a cooperating inner sleeve 21 and outer sleeve 20. The inner wall of the inner sleeve 21 is provided with a fixing ring A 211 and a fixing ring B 212; a first spring 22 is connected between the fixing ring A 211 and the outer sleeve 20; the upper surface of the fixing ring B 212 is connected to a movable plate 27 through a second spring 26. The bottom side of the movable plate 27 is fixed with a first conductor, and a second conductor is arranged inside the inner sleeve 21; the inner top side of the outer sleeve 20 is provided with a push rod 23 for driving the movable plate 27 to move. When the turnstile door assembly is controlled to open, at this time the rotating shaft 10 rotates, and then under the action of the driving structure 3, the outer sleeve 20 is driven to move towards the side close to the inner sleeve 21. Then under the action of the push rod 23, the movable plate 27 is driven to move towards the side close to the inner sleeve 21. Then at this time, the second conductor and the first conductor are controlled to be in contact, and the switch module 2 is in a closed state; when the turnstile door assembly is controlled to close, then under the action of the first spring 22 and the second spring 26, both the movable plate 27 and the outer sleeve 20 return to the initial state, that is, at this time the second conductor and the first conductor are separated, and the switch module 2 is in an open state.

[0067] The first conductor includes a first ceramic sleeve 28, and a first conductive column 281 connected to a first wire 282 is fixed inside the first ceramic sleeve 28; the second conductor includes a second ceramic sleeve 25, and a second conductive column 251 connected to a second wire 252 is fixed inside the second ceramic sleeve 25; an arc protection sleeve 280 sleeved outside the second ceramic sleeve 25 is fixed at the end of the first ceramic sleeve 28; the bottom side of the inner sleeve 21 is connected to a mounting plate 24 through a third spring 23, and the second ceramic sleeve 25 is fixed on the mounting plate 24; both the first wire 282 and the second wire 252 penetrate and are fixed on the mounting plate 24 and the inner sleeve 21.

[0068] Such as Figures 3 - 4 , the driving structure 3 includes a ring body 30 fixed on the rotating shaft 10, and two symmetrically arranged driving parts 31 are provided on the outer wall of the ring body 30; extending from the middle of the driving part 31 to both sides, the distance between the outer wall surface of the driving part 31 and the inner wall surface of the ring body 30 gradually decreases.

[0069] The design of the switch module 2 linked to the rotating shaft 10 realizes the mechanical linkage between the gate action and the infrared detection, reducing the false detection rate.

[0070] Embodiment 5, on the basis of implementing 1 - 2, the alarm component provided by the present invention includes a buzzer and a speaker, and then when in use, hierarchical alarm is realized through the combined use of the buzzer and the speaker.

[0071] For example, primary alarm is realized simply by using the buzzer, secondary alarm is realized by using the speaker, and tertiary alarm is realized by using the buzzer and the speaker.

[0072] Based on the above settings, the present invention is further provided with a detection component for detecting whether the turnstile door assembly is opened, and this detection component is connected to the turnstile controller; when it is detected by the detection component that the turnstile door assembly is opened, at this time, the power component is controlled to stop driving the rotation of the rotating shaft 10; at the same time, when it is detected by this detection component that the turnstile door assembly is closed, at this time, the power component is controlled to stop driving the rotation of the rotating shaft 10.

[0073] That is, the detection component provided by the present invention includes two first detection modules respectively arranged on the side walls of the turnstile main body 1 on both sides of the module door 11, and a second detection module cooperating with the first detection module is arranged on the module door 11, and a third detection module and a fourth detection module which are respectively arranged on the end faces of the two module doors 11 and cooperate with each other.

[0074] The second detection module and the third detection module have the same structure, and both are a magnetic ring;

[0075] Such as Figure 7 , the fourth detection module and the first detection module have the same structure, and both include a cylindrical housing 5. A fixing ring 51 is arranged on the inner wall of the housing 5. The fixing ring 51 is connected by a fourth spring 52 with a magnetic block 53 sliding along the inner wall of the housing 5. One side of the magnetic block 53 is connected with a contact rod 54, and the end of the contact rod 54 is connected with a contact head 55 made of rubber / foam material. A pressure sensor 57 is arranged on the bottom surface of the housing 5, and a sealing plate 56 is arranged at the port of the housing 5; thus, when in use, when the module door 11 is in a closed state, at this time, the third detection module and the fourth detection module cooperate, and by using the repulsive force between the magnetic block 53 and the magnetic ring, at this time, the magnetic block 53 is driven to slide along the inner wall of the housing 5, and then at this time, the contact head 55 abuts against the pressure sensor, and then the pressure sensor 57 corresponding to the fourth detection module generates a signal, indicating that the module door 11 is in a closed state; similarly, when the module door 11 is in an open state, the second detection module and the first detection module cooperate, and by using the repulsive force between the magnetic block 53 and the magnetic ring, at this time, the magnetic block 53 is driven to slide along the inner wall of the housing 5, and then at this time, the contact head 55 abuts against the pressure sensor, and then the pressure sensor 57 corresponding to the first detection module generates a signal, indicating that the module door 11 is in a closed state.

[0076] And as Figure 5 shown, the security alarm device for access control management provided by the present invention has a turnstile main body 1 installed at the entrance and exit position of the area. In order to facilitate actual installation, since the actual entrance and exit position is larger than the installation size of the turnstile main body 1, a guardrail 4 is installed on one side of the turnstile main body 1.
