[0016] The following is a description of exemplary embodiments of the present disclosure in conjunction with the accompanying drawings, including various details of the embodiments of the present disclosure to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present disclosure. Similarly, for clarity and conciseness, descriptions of well-known functions and structures are omitted in the following description. It should be noted that the embodiments in the present disclosure and the features in the embodiments may be combined with each other without conflict.

[0017] In the technical solution of the present disclosure, the collection, storage, use, processing, transmission, provision and disclosure of user personal information involved are in compliance with the provisions of relevant laws and regulations and do not violate public order and good morals.

[0018] In a specific implementation, the access control system includes a terminal device (such as a card reader), a signal transmission line and an access control controller, such as Figure 1 As shown, a card reader 101 is connected to an access controller 103 via a signal transmission line 102 , and the access controller 103 stores valid card swiping information. The access controller 103 receives the card swiping information read by the card reader 101 via the signal transmission line 102 .

[0019] The access controller 103 mainly includes a microprocessor, a storage circuit, a clock circuit and a control circuit. The microprocessor is used to compare information, such as comparing the received card swiping information with the valid card swiping information stored in the storage circuit; the storage circuit is mainly used to store the configuration parameters of the access controller 103, valid card swiping information and door opening and closing time records, etc.; the clock circuit provides the microprocessor with a working clock and door opening and closing time, etc.; the control circuit is connected to the signal transmission line 102 to realize the communication between the access controller 103 and the card reader 101.

[0020] In order to increase the practicality of the access control system, the access control system can include multiple types of terminal devices. For example, the terminal devices include a card reader and a barcode scanner. The card reader can read the card swiping information of the IC card, and the barcode scanner can read the information of the QR code. The setting of the card reader and the barcode scanner can enhance the practicality of the access control system.

[0021] In the case where the terminal device includes a card swiper and a barcode scanner, the card swiper is connected to the access control controller via a signal transmission line 102, and the barcode scanner is connected to the access control controller via another signal transmission line 102. That is, in the case of adding a barcode scanner in the related technology, a signal transmission line 102 corresponding to the barcode scanner needs to be arranged, and the card swiper and the barcode scanner require independent communication lines for communication. This access control system requires additional wiring work, and adding new lines requires complex construction, which may affect the construction and aesthetics of the building structure. In addition, the new wiring and equipment installation require a long construction time, and the wiring and construction costs are high.

[0022] Based on the problem of high wiring and construction costs of the access control system in the related art, the present disclosure provides a new access control device and access control system, which solves the wiring cost and complexity problems faced when adding a barcode scanner function in the related art. When the access control device includes a card swiper and a barcode scanner, the present disclosure can achieve that the card swiper and the barcode scanner share a signal transmission line, thereby significantly reducing the wiring requirements and corresponding construction costs.

[0023] The present disclosure provides a door access control device, such as Figure 2As shown, the access control device includes a signal transmission line 102, at least two types of signal readers 201 and a first combiner 202, wherein the at least two types of signal readers 201 are configured to read and send access control request signals. The input end of the first combiner 202 is connected to the signal reader 201, and the output end of the first combiner 202 is connected to the signal transmission line 102. The first combiner 202 is configured to: receive the access control request signal from the triggered signal reader 201, and send the access control request signal and the type identification of the triggered signal reader 201 to the signal transmission line 102.

[0024] Since the access control device provided by the present disclosure includes at least two types of signal readers, the access control device can read different types of signals, thereby enhancing the practicality of the access control device; and since the access control device includes a first combiner, the input end of the first combiner is respectively connected to different types of signal readers, the output end of the first combiner is connected to the signal transmission line, and the first combiner can receive the access control access request signal from the triggered signal reader, and send the access control access request signal and the type identification of the triggered signal reader to the signal transmission line, the setting of the first combiner can enable different types of signal readers to share a signal transmission line, reducing the need for additional wiring, thereby significantly reducing wiring costs and construction complexity, and at the same time reducing space occupancy and impact on buildings. In addition, the access control device provided by the present disclosure uses a signal transmission line, which can avoid mutual interference between multiple signal transmission lines, ensure the clarity and stability of the signal, thereby improving the reliability of the signal, and further enhancing the security of the access control device.

[0025] The access control device provided in the present disclosure takes two types of signal readers 201 as an example. For example, the access control device includes a first type of signal reader 2011 and a second type of signal reader 2012. In a specific implementation, the first type of signal reader 2011 is, for example, a card reader, and the second type of signal reader 2012 is, for example, a barcode scanner.

[0026] In a specific implementation, the signal transmission line 102 may be an RS-485 signal transmission line, which is also called a 485 line. It is a serial communication interface line with electrical characteristic standards, which is mainly used for digital communication, especially in data transmission between industrial control and automation equipment. Due to its high receiving sensitivity and strong anti-interference ability, the 485 line is widely used in environments with high noise and long transmission distances. The 485 line adopts a differential signal transmission mode, and the noise on the transmission line will be offset by the differential signal, which improves the anti-interference ability of communication and ensures the integrity of the data.

[0027] In a specific embodiment, Figure 3As shown, the access control device provided by the present disclosure also includes a second combiner 203, the input end 33 of the second combiner 203 is connected to the output end 32 of the first combiner 202 through the signal transmission line 102, and the output end 34 of the second combiner 203 includes at least two second ports. The second combiner 203 is configured to: receive the access control access request signal and the type identifier transmitted by the signal transmission line 102, and output the access control access request signal to the second port corresponding to the type identifier. The second combiner 203 is arranged in conjunction with the first combiner 202, and the second combiner 203 can determine whether to output the access control access request signal to the second port 5 or the second port 6 based on the received type identifier and the physical address of each second port, so that the access control access request signals sent by different types of signal readers 201 can be transmitted through different second ports.

[0028] In a specific embodiment, Figure 3 As shown, the input end 31 of the first combiner 202 includes two first ports, for example, the input end 31 of the first combiner 202 includes a first port 1 and a first port 2, one first port is connected to a signal reader 201, for example, the first port 1 is connected to a first type of signal reader 2011, and the first port 2 is connected to a second type of signal reader 2012. The output end 32 of the first combiner 202 includes a port, for example, the output end 32 of the first combiner 202 includes an output port 3, and the output port 3 is connected to the signal transmission line 102.

[0029] It should be noted that the input end 31 of the first combiner 202 can also include more first ports. For example, the number of first ports can be equal to the number of categories of signal readers 201, that is, when the access control device includes three categories of signal readers 201, the number of first ports can be set to three. Of course, the number of first ports can also be set to be greater than the number of categories of signal readers 201, that is, when the access control device includes three categories of signal readers 201, the number of first ports can be set to be greater than three, for example, it can be set to four or five, and the fourth or fifth first port can be used as an extended application of the first combiner 202.

[0030] It should be noted that the input end 33 of the second combiner 203 includes a port, for example, the input end 33 of the second combiner 203 includes an input port 4, and the input port 4 is connected to the signal transmission line 102, and the signal transmission line 102 is an RS-485 signal transmission line. Therefore, in the embodiment of the present disclosure, when a new type of signal reader 201 is added, there is no need to set up a separate RS-485 signal transmission line. The signal transmission line 102 generally requires tens of meters or even hundreds of meters. Saving a signal transmission line 102 can reduce the material cost of wiring, avoid new construction and wiring, and simplify the installation process. In addition, compared with the risk of increased electrical interference and signal attenuation in multi-line layout, the present disclosure can enhance electrical isolation and signal protection, effectively resist external interference, and ensure signal clarity and stability.

[0031] It should be noted that, when the access control device includes two types of signal readers 201, the output end 34 of the second combiner 203 may include two second ports, for example, the output end 34 of the second combiner 203 includes a second port 5 and a second port 6, and the number of the second ports may be the same as the number of the first ports.

[0032] In a specific embodiment, Figure 3 As shown, the type identification transmitted to the signal transmission line 102 includes the physical address of the first port (e.g., the first port 1 or the first port 2) that receives the access control request signal. Since first ports with different physical addresses are connected to different types of signal readers 201, for example, the first port 1 is connected to the card reader, and the first port 2 is connected to the barcode scanner, therefore, in the case where the type identification includes the physical address of the first port that receives the access control request signal, the second combiner 203 can determine to output the access control request signal to the second port 5 or the second port 6 among the multiple second ports according to the received type identification and the physical address of each second port (e.g., the second port 5 and the second port 6), thereby enabling the access control request signals sent by different types of signal readers 201 to be transmitted through different second ports.

[0033] The present disclosure also provides a door access control system, such as Figure 4As shown, the access control system includes an access control controller 402 and at least one access control device 401; the access control device 401 includes a signal transmission line 102, at least two types of signal readers 201 and a first combiner 202. At least two types of signal readers 201 are configured to read and send access control request signals; the input end of the first combiner 202 is connected to the signal reader 201, and the output end of the first combiner 202 is connected to the signal transmission line 102. The first combiner 202 is configured to: receive the access control request signal from the triggered signal reader 201, and send the access control request signal and the type identification of the triggered signal reader 201 to the signal transmission line 102. The access control controller 402 is configured to: receive the access control request signal sent by the signal reader 201 of the same type through the signal transmission line 102, and generate an access control signal based on the access control request signal.

[0034] Since the access control system provided by the present disclosure includes at least one access control device, and the access control device includes at least two types of signal readers, the access control device can read different types of signals, thereby enhancing the practicality of the access control device; and since the access control device includes a first combiner, the input end of the first combiner is respectively connected to different types of signal readers, the output end of the first combiner is connected to the signal transmission line, and the first combiner can receive the access control access request signal from the triggered signal reader, and send the access control access request signal and the type identification of the triggered signal reader to the signal transmission line, the setting of the first combiner can enable different types of signal readers to share a signal transmission line, reducing the need for additional wiring, thereby significantly reducing wiring costs and construction complexity, and at the same time reducing space occupancy and impact on buildings. In addition, the access control device provided by the present disclosure uses a signal transmission line, which can avoid mutual interference between multiple signal transmission lines, ensure the clarity and stability of the signal, thereby improving the reliability of the signal, and further improving the security of the access control system.

[0035] In a specific embodiment, Figure 5As shown, the access control system includes at least two access control controllers 402, and the access control device also includes a second combiner 203, the input end of the second combiner 203 is connected to the output end of the first combiner 202 through the signal transmission line 102, and the output end of the second combiner 203 is connected to the access control controller 402. Among them, the second combiner 203 is configured to: receive the access control access request signal and the type identification transmitted by the signal transmission line 102, and output the access control access request signal to the access control controller 402 corresponding to the type identification. Since the second combiner 203 can output the access control access request signal to the access control controller 402 corresponding to the type identification, the access control controller included in the access control system in the present disclosure can also use the original access control controller, which is used to receive the access control access request signal of the card reader. It only needs to add a new controller, and the newly added access control controller is used to receive the access control access request signal of the barcode scanner. This setting method can make full use of the original access control system, does not require more control method modifications, and can reduce production costs.

[0036] Furthermore, in the access control system provided by the present disclosure, one access control device uses one signal transmission line, and different types of signal readers can be controlled by different access control controllers. Therefore, the access control system of the present disclosure improves data processing speed and accuracy, reduces data conflicts and transmission errors, and improves the overall performance of the access control system. In addition, the first combiner and the second combiner included in the access control device can automatically identify the access device, greatly simplifying the installation and subsequent maintenance work, reducing the dependence on professional technicians, enabling rapid deployment of new equipment, facilitating the expansion and maintenance of the access control system, and improving the stability and reliability of the access control system.

[0037] In a specific embodiment, Figure 5 and Figure 6 As shown, the input end 31 of the first combiner 202 includes at least two first ports (for example, including the first port 1 and the first port 2), and one first port is connected to a signal reader 201. The output end 34 of the second combiner 203 includes at least two second ports (for example, the second port 5 and the second port 6), and one second port is connected to an access controller 402, and one access controller 402 is connected to at least one second port. The input end 31 and the output end 32 of the first combiner 202, and the input end 33 and the output end 34 of the second combiner 203 have been introduced above, and will not be repeated here.

[0038] In a specific implementation, the at least two types of signal readers 201 included in the access control device include a card reader and a barcode scanner, and the signal transmission line 102 included in an access control device 401 is an RS-485 signal transmission line, such as Figure 6As shown, when the number of the access control devices 401 is three, the access control system includes three RS-485 signal transmission lines.

[0039] In a specific embodiment, Figure 6 As shown, the access control system includes multiple access control devices 401, for example, the access control system includes three access control devices 401, one access control device 401 includes a card reader and a barcode scanner, and at least two access control controllers 402 include a first access control controller 4021 and a second access control controller 4022. For example, the first access control controller 4021 can generate an access control signal based on the access access request signal read by the card reader, and the second access control controller 4022 can generate an access control signal based on the access access request signal read by the barcode scanner.

[0040] In a specific embodiment, the access controller 402 is configured to: match the access control access request signal with the pre-stored valid read information, and generate an access control signal in response to a successful match. For example, the first access controller 4021 matches the received card swiping information with the pre-stored valid card swiping information, and the first access controller 4021 generates an access control signal in response to a successful match, and the access control signal can control the electronic lock to open. If the received card swiping information does not match the pre-stored valid card swiping information, that is, if the received card swiping information differs greatly from the pre-stored valid card swiping information, no operation can be performed, or an error message can be fed back through the voice of the card reader. The second access controller 4022 matches the received QR code information with the pre-stored valid QR code information, and the second access controller 4022 generates an access control signal in response to a successful match, and the access control signal can control the electronic lock to open. If the received QR code information does not match the pre-stored valid QR code information, that is, if the received QR code information differs greatly from the pre-stored valid QR code information, no operation can be performed, or an error message can be fed back through the voice of the barcode scanner.

[0041] It should be noted that the received card swiping information successfully matches the pre-stored valid card swiping information, which means that the received card swiping information is the same as or similar to the pre-stored valid card swiping information. The received card swiping information successfully matches the pre-stored valid card swiping information, which means that the received QR code information is the same as or similar to the pre-stored valid QR code information.

[0042] It should be noted that the received card swiping information is similar to the pre-stored valid card swiping information, which means that the difference between the received card swiping information and the pre-stored valid card swiping information is within the allowable error range. The received QR code information is similar to the pre-stored valid QR code information, which means that the difference between the received QR code information and the pre-stored valid QR code information is within the allowable error range.

[0043] In a specific embodiment, Figure 6 As shown, two second ports of the second combiner 203 included in the plurality of access control devices 401 are respectively connected to the first access control controller 4021 and the second access control controller 4022. For example, three access control devices 401 include three second combiners 203, one second end of the first second combiner 203, one second end of the second second combiner 203, and one second end of the third second combiner 203 are connected to the first access control controller 4021, and the other second end of the first second combiner 203, the other second end of the second second combiner 203, and the other second end of the third second combiner 203 are connected to the second access control controller 4022.

[0044] In a specific embodiment, Figure 5 As shown, the type identification sent to the signal transmission line 102 includes the physical address of the first port that receives the access control request signal; the second combiner 203 is configured to: output the access control request signal to the second port corresponding to the physical address.

[0045] The transmission method of the access control request signal disclosed in the present invention is described in detail below with reference to a specific embodiment.

[0046] like Figure 5 and Figure 6 As shown, the first type of signal reader 2011 is a card swiping machine, and the second type of signal reader 2012 is a barcode scanner. The access control request signal read and sent by the card swiping machine needs to be transmitted to the first access control controller 4021, and the first access control controller 4021 generates an access control signal based on the access control request signal read by the card swiping machine; the access control access request signal read and sent by the barcode scanner needs to be transmitted to the second access control controller 4022, and the second access control controller 4022 generates an access control signal based on the access control request signal read by the barcode scanner.

[0047] The card swiper is connected to the first port 1, the barcode scanner is connected to the first port 2, the first access control controller 4021 is connected to the second port 5, and the second access control controller 4022 is connected to the second port 6. When the card swiper sends an access control access request signal, the first port 1 receives the access control access request signal; when the barcode scanner sends an access control access request signal, the first port 2 receives the access control access request signal; when the first port 1 receives the access control access request signal, the first combiner 202 generates a type identifier including the physical address of the first port 1; when the first port 2 receives the access control access request signal, the first combiner 202 generates a type identifier including the physical address of the first port 2.

[0048] When the second combiner 203 receives a type identifier including the physical address of the first port 1, the second combiner 203 outputs the access control request signal to the first access control controller 4021 through the second port 5 according to the physical address of the second port 5. When the second combiner 203 receives a type identifier including the physical address of the first port 2, the second combiner 203 outputs the access control access request signal to the second access control controller 4022 through the second port 6 according to the physical address of the second port 6.

[0049] The disclosed embodiment also provides a control method for a door access system, such as Figure 7 As shown, Figure 7 A flow chart of a control method of a door access control system provided in an embodiment of the present disclosure includes the following steps:

[0050] S101: A first combiner receives a door access request signal from a triggered signal reader.

[0051] S102: The first combiner sends the access control request signal and the type identifier of the triggered signal reader to the signal transmission line.

[0052] This step is intended to distinguish the type of signal reader that is triggered so that the corresponding access controller can be selected later.

[0053] S103: The access control controller receives, via the signal transmission line, an access control access request signal sent by a signal reader of the same type.

[0054] S104: The access controller generates an access control signal based on the access access request signal.

[0055] In the control method of the access control system provided by the embodiment of the present disclosure, since the first combiner can receive the access control access request signal from the triggered signal reader and send the access control access request signal and the type identification of the triggered signal reader to the signal transmission line, the setting of the first combiner can enable different types of signal readers to share a signal transmission line, reducing the need for additional wiring, thereby significantly reducing the wiring cost and construction complexity, and at the same time reducing space occupation and the impact on the building. In addition, the access control device provided by the present disclosure uses a signal transmission line, which can avoid mutual interference between multiple signal transmission lines, ensure the clarity and stability of the signal, thereby improving the reliability of the signal, and further enhancing the security of the access control system.

[0056] In a specific implementation, the access control device further includes a second combiner, and the control method of the access control system further includes: the second combiner receives the access control access request signal and the type identifier transmitted by the signal transmission line; the second combiner outputs the access control access request signal to the access control controller corresponding to the type identifier. This step is intended to select different types of access control controllers for different types of signal readers, thereby improving the scalability of the access control system and the flexibility of future upgrades.

[0057] In a specific embodiment, the input end of the first combiner includes at least two first ports, and the type identifier includes the physical address of the first port that receives the access control access request signal. The input end and output end of the first combiner, as well as the relevant instructions on the type identifier have been described in the previous text and will not be repeated here.

[0058] In a specific implementation, the access control device further includes a second combiner, and the output end of the second combiner includes at least two second ports; the control method of the access control system further includes: the second combiner outputs the access control access request signal to the second port corresponding to the physical address. The relevant description of how the second combiner outputs the access control access request signal to the second port corresponding to the physical address has been described above and will not be repeated here.

[0059] In a specific implementation, the access controller generates an access control signal based on the access access request signal, including: the access controller matches the access access request signal with pre-stored valid read information, and the access controller generates the access control signal in response to a successful match. The specific implementation of this step has been described in the previous text and will not be repeated here.

[0060] According to the technical solution of the embodiment of the present disclosure, since the access control device provided by the present disclosure includes at least two types of signal readers, the access control device can read different types of signals, thereby enhancing the practicality of the access control device; and since the access control device includes a first combiner, the input end of the first combiner is respectively connected to different types of signal readers, the output end of the first combiner is connected to the signal transmission line, and the first combiner can receive the access control access request signal from the triggered signal reader, and send the access control access request signal and the type identification of the triggered signal reader to the signal transmission line, so the setting of the first combiner can enable different types of signal readers to share a signal transmission line, reducing the need for additional wiring, thereby significantly reducing the wiring cost and construction complexity, and at the same time reducing space occupation and the impact on the building. In addition, the access control device provided by the present disclosure uses a signal transmission line, which can avoid mutual interference between multiple signal transmission lines, ensure the clarity and stability of the signal, thereby improving the reliability of the signal, and further improving the security of the access control device.

[0061] In addition, in the access control system provided by the present invention, different types of signal readers can be controlled by different access control controllers. Therefore, the access control system of the present invention improves data processing speed and accuracy, reduces data conflicts and transmission errors, improves the overall performance of the access control system, and further improves the security of the access control equipment.

[0062] In addition, the first combiner and the second combiner included in the access control device can automatically identify the access device, which greatly simplifies the installation and subsequent maintenance work, reduces the dependence on professional technicians, can quickly deploy new equipment, facilitates the expansion and maintenance of the access control system, and improves the stability and reliability of the access control system.
