Detailed Implementation

[0039] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0040] Access control systems include multiple external interfaces to control multiple entrances and exits. Taking a six-door access control system as an example... Figure 1 This is a connection diagram of existing access control management equipment and peripheral devices, such as... Figure 1 As shown, the six-door access control management device includes six sets of external interfaces. Each set of external interfaces is connected to access control supporting equipment, including six door locks, twelve card readers, six door opening buttons, six door magnetic sensors, six alarm inputs, and six alarm outputs, through the Phoenix terminals on the single board. The six-door access control management device has a large number of external devices connected to it, and the distance between the six-door access control management device and the external devices is generally far. Long cables are required to connect the Phoenix terminals of each set of external interfaces to each external device, so the following disadvantages exist.

[0041] (1) A large number of lines need to be laid between the access control equipment and the peripheral equipment. In some old buildings or places with complex structures, it is difficult to lay the lines. For example, it is difficult to drill through the wall and there are limited wiring pipes, which increases the difficulty and workload of installation.

[0042] (2) Due to the large number of connected peripheral devices and the variety of wiring, wiring errors are prone to occur. For example, connecting the card reader's signal line to the wrong position may cause the card reader to malfunction, or reversing the power line of the electric lock may damage the electric lock or controller. Once a wiring error occurs, troubleshooting and repairing the problem is relatively difficult and requires a lot of time and effort.

[0043] (3) The maintenance and upgrade of the later stage are more difficult. For example, when replacing the access control management device 100, due to the limitations of the existing wiring method, it may be necessary to lay new lines or make large-scale adjustments to the original lines. This will not only affect normal use, but may also bring high transformation costs.

[0044] (4) Signal interference: In some places with complex electromagnetic environments, such as near large electrical equipment or wireless communication base stations, the wiring method of long cables of access control equipment may be subject to electromagnetic interference, and there may also be interference between signals, resulting in unstable signal transmission and affecting the normal operation of the access control system.

[0045] Therefore, in view of the problems of complex and cumbersome wiring, high wiring failure rate, high maintenance difficulty and expansion difficulty in the existing technology, this utility model embodiment provides a wiring device for access control management equipment. Figure 2 This is one of the structural schematic diagrams of the wiring device for the access control management equipment provided in this utility model embodiment, such as... Figure 2 As shown, the access control management equipment wiring device includes: access control management equipment 100, at least two wiring boxes 200 and matching cables 300 corresponding to each wiring box 200.

[0046] All wiring boxes 200 are connected via network ports to form a bidirectional transmission link. The wiring boxes 200 located at both ends of the bidirectional transmission link are connected to the access control management device 100.

[0047] Each of the wiring boxes 200 is connected to a corresponding matching cable 300, and a corresponding peripheral device is connected based on the matching cable 300.

[0048] Each of the wiring boxes 200 is used to convert the interface signals sent by the corresponding peripheral devices into network signals and send the network signals to the access control management device 100.

[0049] Specifically, in this embodiment of the utility model, at least two wiring boxes 200 are provided, each wiring box 200 is connected to a corresponding matching cable 300, and is connected to a corresponding peripheral device through the corresponding matching cable 300. Each wiring box 200 is connected to a set of peripheral devices. For example, a wiring box 200 can be connected to a door lock, card reader, door opening button, door magnetic sensor, alarm input and alarm output through the matching cable 300. Multiple wiring boxes 200 can be connected to multiple sets of peripheral devices, realizing group wiring and step-by-step wiring of multiple sets of peripheral devices, meeting the development trend of the increasing number of entrances and exits of access control management equipment 100, while simplifying the wiring process and reducing installation difficulty and error probability.

[0050] All cabling boxes 200 are looped together, and bidirectional transmission is possible between adjacent cabling boxes 200, forming a bidirectional transmission link. The cabling boxes 200 at both ends of this bidirectional transmission link are connected to the access control device 100 via network cables. This bidirectional transmission link and the access control device 100 form a loopback link, and only two network cables exist between them, significantly reducing the number of cables. After any cabling box 200 in the bidirectional transmission link converts the interface signal sent by the corresponding peripheral device into a network signal, it can be transmitted bidirectionally through the link. If one network cable experiences a communication failure, the signal can be transmitted to the access control device 100 via the other network cable, ensuring that the access control device 100 can receive the network signal without affecting its normal operation. The signal transmission reliability and stability are high, and the redundancy and fault tolerance capabilities are strong.

[0051] The bidirectional transmission link uses multiple cabling boxes 200 for multi-point layout. If a new node needs to be added to the loopback link, only cabling box 200 needs to be added to the bidirectional transmission link without changing the entire cabling structure. Moreover, each cabling box 200 can be segmented to realize segmented detection and maintenance of the line. This greatly reduces the difficulty of expansion and maintenance without affecting the overall operation, and reduces maintenance and expansion costs.

[0052] Optionally, the network cable between the wiring box 200 and the access control management device 100 can be an RJ45 long cable. With the number of long cables between the wiring box 200 and the access control management device 100 significantly reduced, the RJ45 long cable is equipped with an external shielding layer. Furthermore, network signals are used for transmission between wiring boxes 200 and between wiring boxes 200 and the access control management device 100, which can reduce electromagnetic interference and interference between signals, ensure stable signal transmission, and guarantee the normal operation of the access control system.

[0053] Optionally, the access control management device 100 can be a two-door access control management device 100, a four-door access control management device 100, or a six-door access control management device 100, etc., and this utility model embodiment does not limit this. For example, when the access control management device 100 is a six-door access control management device 100, six wiring boxes are connected accordingly, and the corresponding peripheral devices may include a six-way door lock, a twelve-way card reader, a six-way door opening button, a six-way door magnetic sensor, a six-way alarm input, and a six-way alarm output.

[0054] Furthermore, the cabling box 200 includes a first network port 201 and a second network port 202, wherein:

[0055] The second network port 202 of the preceding cabling box 200 is connected to the first network port 201 of the following cabling box 200 to form the bidirectional transmission link.

[0056] The first cabling box 200 in the bidirectional transmission link is connected to the access control management device 100 through the first network port 201, and the last cabling box 200 in the bidirectional transmission link is connected to the access control management device 100 through the second network port 202.

[0057] For example, Figure 3 This is one of the structural schematic diagrams of the wiring box provided in this embodiment of the utility model, such as... Figure 3As shown, when the number of wiring boxes 200 is n, a loopback connection of n wiring boxes 200 means that the first wiring box 200 is connected to the access control management device 100 through the first network port 201, and is connected to the first network port 201 of the second wiring box 200 through the second network port 202, thus realizing a series connection between the first and second wiring boxes 200. The second network port 202 of the second wiring box 200 is connected to the first network port 201 of the wiring box 2003, thus realizing a series connection between the second wiring box 200 and the wiring box 2003. Repeating the above connection, the second network port 202 of the (n-1)th wiring box 200 is connected to the first network port 201 of the nth wiring box 200, realizing the series connection between the (n-1)th wiring box 200 and the nth wiring box 200. The second network port 202 of the nth wiring box 200 is connected to the access control management device 100. Thus, after the loopback connection of the n wiring boxes 200 is achieved, a loopback link is formed with the access control management device 100, and the n wiring boxes 200 can transmit network signals to each other through the network ports. Taking the first wiring box 200 as an example, after converting the interface signal sent by the corresponding peripheral device into a network signal, the first wiring box 200 can directly transmit the network signal to the access control management device 100 through the first network port 201 and the network cable. Simultaneously, it transmits the signal to the access control management device 100 through the second network port 202, the second wiring box 200 to the nth wiring box 200, and the network cable connected to the nth wiring box 200, achieving bidirectional transmission. It should be noted that n is an integer greater than or equal to 2.

[0058] Furthermore, Figure 4 This is a second structural schematic diagram of the wiring device for the access control management equipment provided in this embodiment of the utility model, as shown below. Figure 4 As shown, when the access control management device 100 includes a third network port 110 and a fourth network port 120, the first wiring box 200 in the bidirectional transmission link is connected to the third network port 110 through the first network port 201, and the last wiring box 200 in the bidirectional transmission link is connected to the fourth network port 120 through the second network port 202.

[0059] For example, if the access control management device 100 has dual network ports, the first wiring box 200 can be connected to the third network port 110 in the access control management device 100 through the first network port 201 and a network cable, and the nth wiring box 200 can be connected to the fourth network port 120 in the access control management device 100 through the second network port 202 and a network cable, which is suitable for the use environment without a switch 400.

[0060] Furthermore, Figure 5 This is the third structural schematic diagram of the wiring device for the access control management equipment provided in this embodiment of the utility model, as shown below. Figure 5As shown, when the access control management device 100 includes a fifth network port 130, it also includes a switch 400. The first cabling box 200 in the bidirectional transmission link is connected to the switch 400 through a first network port 201, and the last cabling box 200 in the bidirectional transmission link is connected to the switch 400 through a second network port 202. The switch 400 is connected to the fifth network port 130.

[0061] For example, if the access control device 100 has a single network port, a switch 400 needs to be installed between the access control device 100 and each wiring box 200. The first wiring box 200 can be connected to one of the network ports of the switch 400 via its first network port 201 and a network cable. The nth wiring box 200 can be connected to another network port of the switch 400 via its second network port 202 and a network cable. The network ports of the switch 400 connected to the first wiring box 200 and the nth wiring box 200 are different. The switch 400 is connected to the fifth network port 130 of the access control device 100, simplifying wiring and enabling network interconnection and data transmission between the wiring boxes 200 and the access control device 100.

[0062] Furthermore, Figure 6 This is a second structural schematic diagram of the wiring box provided in this embodiment of the utility model, as shown below. Figure 6 As shown, the wiring box 200 also includes at least two external interfaces 203 and a signal conversion module 204, wherein:

[0063] All external interfaces 203 are connected to the corresponding internal interfaces 301 in the supporting cable 300, and all external interfaces 203 are connected to the signal conversion module 204.

[0064] The signal conversion module 204 is used to receive the interface signals of the corresponding peripheral devices transmitted by each of the external interfaces 203, convert each of the interface signals into network signals, and send each of the network signals to the access control management device 100.

[0065] For example, the front shell of the wiring box 200 is fastened to the PCB board with fasteners. Multiple external interfaces 203 are soldered onto the PCB board. These external interfaces 203 are pin-type connectors, visible from the front for easy connection. For instance, each wiring box 200 may include six external interfaces 203: an alarm output interface, an alarm input interface, a door sensor interface, a door lock interface, a door opening button interface, and a card reader interface. The card reader interface can receive 485 or Wiegand signals from the card reader via a matching cable 300. All other interfaces besides the card reader interface are GPIO (General-purpose input / output) interfaces, and can receive GPIO signals from their respective peripheral devices via the matching cable 300. That is, the interface signals received by the external interface 203 may include at least one of GPIO signals, 485 signals, and Wiegand signals.

[0066] After receiving an interface signal, each external interface 203 can send the interface signal to the signal conversion module 204. The signal conversion module 204 can convert the interface signal into a network signal and send the network signal to the access control management device 100. In addition, it can also receive control commands sent by the access control management device 100 and accurately send the control commands to the corresponding peripheral devices to realize the control of the entire access control management system.

[0067] Furthermore, such as Figure 6 As shown, the signal conversion module 204 includes a microcontroller unit 205, a GPIO signal conversion component 206, and at least one card reader signal conversion unit 209, wherein:

[0068] The microcontroller unit 205 connects all the GPIO external interfaces in the external interfaces 203 and the GPIO signal conversion component 206. The microcontroller unit 205 is used to forward the interface signals of the corresponding peripheral devices transmitted by all the GPIO external interfaces to the GPIO signal conversion component 206.

[0069] The GPIO signal conversion component 206 is connected to the first network port 201 and the second network port 202. The GPIO signal conversion component 206 is used to convert each of the interface signals into network signals and transmit the network signals to the access control management device 100 through the first network port 201 and the second network port 202.

[0070] The at least one card reader signal conversion unit 209 is connected to at least one card reader external interface among all external interfaces 203, and all card reader signal conversion units 209 are connected to the first network port 201 and the second network port 202. Each card reader signal conversion unit 209 is used to convert the interface signal transmitted by the corresponding card reader external interface into a network signal, and transmit the network signal bidirectionally to the access control management device 100 through the first network port 201 and the second network port 202.

[0071] For example, taking a six-door access control device 100 as an example, the wiring device of this access control device includes six loop-connected wiring boxes 200. Taking the first wiring box 200 as an example, the microcontroller unit 205 connects to five GPIO external interfaces: alarm output external interface, alarm input external interface, door magnetic external interface, door lock external interface, and door opening button external interface. After receiving a GPIO signal, these five GPIO external interfaces can send the GPIO signal to the microcontroller unit 205, and the microcontroller unit 205 can forward the GPIO signal to the GPIO external interface. The PIO signal conversion component 206 converts GPIO signals into network signals. The GPIO signal conversion component 206 can also send the converted network signals to the first network port 201 and the second network port 202 of the first wiring box 200. The network signals are transmitted to the access control management device 100 through the first network port 201 and to the first network port 201 of the second wiring box 200 through the second network port 202. The network signals are transmitted to the access control management device 100 through the second to the sixth wiring boxes 200 in sequence. Taking the third wiring box 200 as an example, after the GPIO signal conversion component 206 converts the GPIO signal into a network signal, the GPIO signal conversion component 206 can transmit the network signal to the second network port 202 of the second wiring box 200 through the first network port 201, and transmit the network signal to the access control management device 100 through the second wiring box 200 and the first wiring box 200. In addition, the GPIO signal conversion component 206 can also transmit the network signal to the first network port 201 of the fourth wiring box 200 through the second network port 202, and transmit the network signal to the access control management device 100 through the fourth to sixth wiring boxes 200.

[0072] It should be noted that the data transmitted by the first network port 201 and the second network port 202 is the same. That is, after converting the interface signals received by each external interface into network signals, the network signals are simultaneously transmitted bidirectionally to the access control management device 100 through the first network port 201 and the second network port 202.

[0073] Furthermore, if the interface signal sent by the card reader through its external interface is a Wiegand signal, the card reader signal conversion unit 209 connected to the external interface is a Wiegand-to-Ethernet module, which can convert the Wiegand signal into a network signal. If the interface signal sent by the card reader through its external interface is a RS-485 signal, the card reader signal conversion unit 209 connected to the external interface is a RS-485-to-Ethernet module, which can convert the RS-485 signal into a network signal. In the case where the access control management equipment wiring device includes six loop-connected wiring boxes 200, after the card reader signal conversion unit 209 converts the Wiegand signal or 485 signal into a network signal, taking the first wiring box 200 as an example, the card reader signal conversion unit 209 transmits the network signal to the access control management device 100 through the first network port 201, and transmits the network signal to the first network port 201 of the second wiring box 200 through the second network port 202, and so on, transmitting the network signal to the access control management device 100 through the second to the sixth wiring boxes 200 in sequence. Taking the fifth wiring box 200 as an example, the card reader signal conversion unit 209 can transmit network signals to the second network port 202 of the fourth wiring box 200 through the first network port 201, and transmit network signals to the access control management device 100 through the fourth wiring box 200 to the first wiring box 200. In addition, the card reader signal conversion unit 209 can also transmit network signals to the first network port 201 of the sixth wiring box 200 through the second network port 202, and transmit network signals to the access control management device 100 through the second network port of the sixth wiring box 200.

[0074] Furthermore, such as Figure 6 As shown, the GPIO signal conversion component 206 includes a first PHY (Physical, port physical layer) chip 207 and a second PHY chip 208, wherein:

[0075] Both the first PHY chip 207 and the second PHY chip 208 are connected to the microcontroller unit 205, and the first PHY chip 207 is connected to the first network port 201, while the second PHY chip 208 is connected to the second network port 202.

[0076] Specifically, the first PHY chip 207 and the second PHY chip 208 transmit network signals in opposite directions. For example, taking the first wiring box 200 as an example, after the microcontroller unit 205 receives a GPIO signal, it can send the GPIO signal to the first PHY chip 207 and the second PHY chip 208. Both the first PHY chip 207 and the second PHY chip 208 can convert the GPIO signal into a network signal. The first PHY chip 207 can directly send the network signal to the access control device 100 through the first network port 201 and the network cable. The second PHY chip 208 can send the network signal to the first network port 201 of the adjacent second wiring box 200 through the second network port 202, and then send it to the access control device 100 through n-1 wiring boxes 200 and network cables in a bidirectional transmission link.

[0077] Furthermore, such as Figure 6 As shown, the wiring box 200 also includes a power module 210 and at least two indicator lights 211, wherein:

[0078] All indicator lights 211 are connected to all external interfaces 203, and all indicator lights 211 are connected to the microcontroller unit 205;

[0079] The power module 210 is connected to the microcontroller unit 205.

[0080] Specifically, the power module 210 can meet the power supply needs of different modules within the wiring box 200, and the indicator lights 211 can be LED beads. The number of indicator lights 211 is equal to the number of external interfaces 203, and they correspond one-to-one. The indicator lights 211 can use different colors to indicate whether interface signals are being transmitted.
