Description

Technical Field

[0001] The present invention relates to the technical field of access control, and particularly to a detachable and upgradable access control reader head. Background Art

[0002] An access control system is an intelligent management system for managing personnel access. With the development of identification systems, the identification methods of access control systems are becoming more and more diverse. For example, currently common identification methods include: password identification, fingerprint identification, face recognition, radio frequency identification (access control card), etc.

[0003] However, in actual applications, access control does not need to have all the above identification methods at once. Different scenarios have different requirements for identification methods. When users change the usage scenarios, they may need new identification methods, and then they need to purchase new access control systems, resulting in insufficient flexibility of the access control system. Summary of the Invention

[0004] The main object of the present invention is to provide a detachable and upgradable access control reader head. Through the detachable design of the reader head and the access control main body, users can purchase different reader heads according to actual needs to adjust the identification method of the access control system and improve the flexibility of the access control system.

[0005] In some embodiments, the detachable and upgradable access control reader head includes:

[0006] An access control main body, including: a first housing, and a main controller, a first mechanical connection portion, and a first electrical connection portion provided on the housing. The main controller is communicatively connected to the first electrical connection portion;

[0007] A reader head, including: a second housing, and a detection member, a second mechanical connection portion, and a second electrical connection portion provided on the second housing. The detection member is communicatively connected to the second electrical connection portion;

[0008] Wherein, when the first mechanical connection portion and the second mechanical connection portion are in a connected state with each other, the first electrical connection portion and the second electrical connection portion are communicatively connected, so that the main controller is communicatively connected to the detection member.

[0009] In some embodiments, the first housing is provided with a sealing portion surrounding the first electrical connection portion. When the first mechanical connection portion and the second mechanical connection portion are in a connected state with each other, the sealing portion abuts against the second housing to form a sealed space for sealing the first electrical connection portion.

[0010] In some embodiments, the sealing portion is made of an elastic material. When the first mechanical connection portion and the second mechanical connection portion are in a connected state with each other, the sealing portion undergoes elastic deformation to form the sealed space.

[0011] In some embodiments, the detection component includes one or a combination of the following: a fingerprint recognition device, a face recognition device, a numeric keypad module, and a radio frequency identification device.

[0012] In some embodiments, the first electrical connection part and the second electrical connection part are spring pin connectors.

[0013] In some embodiments, the first electrical connection part and the second electrical connection part are USB interfaces.

[0014] In some embodiments, the reader further includes:

[0015] a backup power supply connected to the second electrical connection part;

[0016] a power supply circuit connected to the backup power supply. The power supply circuit is configured to supply power to the access control main body when it detects that the access control main body loses power, and to obtain a power supply from the access control main body to supply power to the backup power supply when the access control main body is powered on.

[0017] In some embodiments, the power supply circuit is connected to the detection component. The power supply circuit responds to a detection signal triggered by the detection component to control the backup power supply to supply power to the access control main body when it detects that the access control main body loses power; wherein, the detection signal indicates that the detection component has detected the identification information of an authorized person.

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0027] In addition, in the present invention, descriptions such as "first" and "second" are only for descriptive purposes, and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0028] It should be noted that the access control main body 10 and the access control reader 20 of the traditional access control system are integrally designed. That is to say, when a user purchases an access control system, it is necessary to confirm the identification method of the required access control system. When wanting to change the identification method of the access control system subsequently, it is necessary to purchase a new access control system again, which brings relatively high economic costs and installation time costs.

[0029] To solve the above technical problems, the present application proposes a detachable and upgradable access control reader 20. By detachably designing the access control main body 10 and the reader 20, when the user needs to upgrade the unlocking and identification method of the access control, the corresponding reader 20 can be replaced to achieve the replacement of the identification method. In addition, with the rapid development of identification methods, when a new identification method appears, the user can also purchase the reader 20 corresponding to the identification method to achieve the upgrade of the identification method.

[0030] Specifically, in some embodiments, the access control main body 10 of the above detachable and upgradable access control reader 20 includes: a first housing, and a main controller, a first mechanical connection part, and a first electrical connection part provided on the housing. The main controller is communicatively connected to the first electrical connection part;

[0031] The reader 20 of the above detachable and upgradable access control reader 20 includes: a second housing, and a detection part, a second mechanical connection part, and a second electrical connection part provided on the second housing. The detection part is communicatively connected to the second electrical connection part;

[0032] Wherein, when the first mechanical connection part and the second mechanical connection part are in a connected state with each other, the first electrical connection part and the second electrical connection part are communicatively connected, so that the main controller is communicatively connected to the detection part.

[0033] In this embodiment, the connection method of the first mechanical connection part and the second mechanical connection part is not limited, as long as the detachable connection and quick installation of the access control main body 10 and the reader 20 can be achieved.

[0034] For example, the first mechanical connection part and the second mechanical connection part are a lock structure, a screw locking structure, a plunger structure, a snap structure, etc. Exemplarily, in order to prevent the detachable reader 20 from being stolen, in practical applications, the access control main body 10 and the reader 20 can use a lock structure, and the unlocking of the lock structure can be achieved by a key or the detection part of the reader 20. The specific structure is relatively conventional and will not be elaborated here. Exemplarily, for the convenience of installation, a screw locking structure can be used, which can avoid the malicious disassembly by children and is convenient for the installation of the reader 20.

[0035] In this embodiment, when the first mechanical connection part and the second mechanical connection part are in a connected state with each other, the first electrical connection part and the second electrical connection part. Exemplarily, the first electrical connection part is a USB interface, and the second electrical connection part is a USB plug; Exemplarily, in order to simplify the installation, both the first electrical connection part and the second electrical connection part are USB interfaces in the form of pogopin (spring pin connector 21),

[0036] In this application, the access control main body 10 and the reader 20 of the access control system are detachably designed. When the user needs to upgrade the unlocking and identification method of the access control, the corresponding reader 20 can be replaced to achieve the replacement of the identification method. Specifically, by providing a first mechanical connection part and a first electrical connection part on the access control main body 10, and a second mechanical connection part and a second electrical connection part at the reader 20, when the first mechanical connection part and the second mechanical connection part are in a connected state, the first electrical connection part and the second electrical connection part are communicatively connected, so that the main controller is communicatively connected to the detection component. When the reader 20 needs to be replaced, only the mechanical connection between the first mechanical connection part and the second mechanical connection part needs to be disconnected, and then the reader 20 can be replaced, improving the flexibility of the access control system.

[0037] In some embodiments, the first housing is provided with a sealing part surrounding the first electrical connection part. When the first mechanical connection part and the second mechanical connection part are in a connected state, the sealing part abuts against the second housing to form a sealed space for sealing the first electrical connection part.

[0038] It should be noted that the access control system is often installed outdoors, and there may be scenarios such as rain or other situations where water can enter. To ensure the safety of the electronic components of the access control main body 10 and the reader 20, a sealing part is also provided in this embodiment to form a sealed space to seal the first electrical connection part and the second electrical connection part.

[0039] Exemplarily, if the first electrical connection part is a USB interface, the sealing part can be a sealing gasket surrounding the USB interface, and the height of the gasket can be such that after the USB interface and the USB plug are plugged in, they abut against the second housing to form a sealing part for sealing the USB interface and the USB plug.

[0040] In other embodiments, the first electrical connection part and the second electrical connection part are spring pin connectors 21, so that the connection height is lower, and the sealing gasket can better seal the two.

[0041] In some embodiments, the sealing part is made of an elastic material. When the first mechanical connection part and the second mechanical connection part are in a connected state, the sealing part undergoes elastic deformation to form the sealed space. For example, the sealing part is a silicone gasket.

[0042] In some embodiments, the detection component includes one or a combination of a fingerprint recognition device, a face recognition device, a numeric keypad module, and a radio frequency identification device.

[0043] In addition to the above categories, the detection component can also be other devices that can achieve identity recognition.

[0044] In practical applications, the access control system can have multiple first mechanical connection parts and first electrical connection parts to install multiple readers 20 to achieve multiple identification methods.

[0045] In practical applications, one reader 20 can be equipped with one type of detection component, or one reader 20 can also be equipped with multiple types of detection components. For example, one reader 20 includes a fingerprint recognition device and a numeric keypad module.

[0046] In some embodiments, the first electrical connection part and the second electrical connection part are spring pin connectors 21.

[0047] In some embodiments, all the first electrical connection parts and the second electrical connection part are USB interfaces.

[0048] In some embodiments, the reader 20 further includes:

[0049] A backup power supply connected to the second electrical connection part;

[0050] A power circuit connected to the backup power supply. The power circuit is used to supply power to the access control main body 10 when it is detected that the access control main body 10 loses power, and obtain a power supply from the access control main body 10 to supply power to the backup power supply when the access control main body 10 is powered on.

[0051] In practical applications, the battery of the backup power supply can be set to be small to reduce the cost of the reader 20.

[0052] It should be noted that under normal working conditions, the reader 20 of the present application is powered by the access control main body 10, and the access control main body 10 can be directly powered by the mains. Further, a battery can also be provided inside the access control main body 10 to supply power to the access control main body 10 and the reader 20 when the mains power is cut off to achieve unlocking of the access control system.

[0053] However, in some extreme working conditions, such as when both the mains power and the battery of the access control main body 10 are out of power, or when the battery of the access control main body 10 is damaged and the mains power is cut off, the access control system cannot be unlocked, which will cause very bad effects.

[0054] In the present application, by providing a backup power supply at the reader 20 and setting the backup power supply to be small, such as less than 1000 mAh, 500 mAh, 300 mAh, 200 mAh, 100 mAh, 50 mAh, it not only ensures the low cost of the reader 20, but also ensures that the access control system can be unlocked under the above extreme working conditions. Of course, when the access control main body 10 is powered on, the power of the access control main body 10 is preferentially used, and the logic of preferential power supply is relatively common and will not be elaborated here. For example, the voltage of the backup power supply is set slightly lower than the battery output voltage of the access control main body 10, or a switching tube is set to switch the power supply.

[0055] In some embodiments, the power supply circuit is connected to the detection component, and the power supply circuit responds to the detection signal triggered by the detection component to control the backup power supply to supply power to the access control main body 10 when it detects that the access control main body 10 is powered off; wherein, the detection signal represents that the detection component detects the identification information of an authorized person.

[0056] In this embodiment, since the backup battery of the reader head 20 is relatively small, it is set in this embodiment that when the access control main body 10 is powered off, the reader head 20 only supplies power to its own power consumption module until the detection component detects the identification information of an authorized person, such as correct fingerprint information or password information, and then supplies power to the access control main body 10, which greatly avoids power waste, resulting in the depletion of the backup battery circuit and the inability to unlock in extreme working conditions.

[0057] In some embodiments, the first mechanical connection portion includes an adsorbing member made of iron material, and the second mechanical connection portion includes a magnetic attracting member to magnetically attract the adsorbing member.

[0058] In some embodiments, the access control main body 10 further includes:

[0059] A Hall sensor, connected to the main controller, and the Hall sensor is used to trigger a signal indicating that the reader head 20 is in place to the main controller when it detects the magnetic attracting member.

[0060] This application also provides an access control system, which may include the detachable and upgradeable access control reader head 20 described above, and a lock body.

[0061] Among them, the specific structure of the detachable and upgradeable access control reader head 20 refers to the above embodiments. Since this embodiment has the technical solutions of the above embodiments, it has the technical effects of the above embodiments, which will not be elaborated here.

[0062] The above are only optional embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structural transformation made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied to other related technical fields, is included in the patent protection scope of the present invention.
