Description

Technical Field

[0001] This invention relates to the field of access control technology, and specifically to a communication control board for parallel compatibility of different access control systems and a method for replacing access control systems. Background Technology

[0002] like Figure 1 The diagram illustrates the basic architecture of a typical access control system in the prior art. This system includes a card reader 11, an access controller 12, and management software 13. Communication between the card reader 11 and the access controller 12 is typically Wiegand, an international standard. However, communication between the access controller 12 and the management software 13 is a proprietary design by the manufacturer. Currently, each manufacturer's access control products and systems have undisclosed proprietary designs, making them incompatible. Because of this incompatibility, if a user needs to introduce products from a different manufacturer, all products must be replaced, requiring a complete interruption of normal business operations. This modification must be completed in one go and cannot be done in phases. Once the new manufacturer's products are installed, changes are impossible, and the owner has no opportunity to back out, even without sufficient verification of the new system.

[0003] To address the issue of business interruption during access control system replacement, a common solution in existing technologies includes... Figure 2 As shown, a unified management system, namely the master management software 14, is built on top of two access control systems. This master management software 14 connects to the private API interfaces of management software 13 and management software 13a (the newly introduced access control system). This allows for phased implementation of the new access control system while ensuring the original access control system continues to operate during the replacement process, avoiding disruption to normal business operations. However, most access control manufacturers, especially imported ones, do not provide data sharing interfaces and third-party control interfaces by default; these must be purchased separately at very high prices. Furthermore, due to limitations on the number of users, not all system functions can be implemented. Building the master management software 14 requires purchasing API data sharing interfaces and control interfaces from both access control systems and performing secondary development on each API. Once the system replacement is complete, all the original API development is wasted. If the newly developed master management software 14 is used after the renovation, 100% of the system functionality cannot be achieved. If the new access control system's management software 13a is chosen, the entire newly developed portion is wasted. The method of building the overall management software 14 also has drawbacks such as a lengthy development and debugging cycle, a large investment in personnel and equipment, and a lengthy reconstruction cycle. Summary of the Invention

[0004] The present application aims at overcoming the defects of the prior art, and provides a communication control board for parallel compatibility of different access control systems and a method for replacing an access control system, so as to solve the problems of additional investment and waste existing in the construction of a unified management system.

[0005] The technical solution for achieving the above object is:

[0006] The present application provides a communication control board for parallel compatibility of different access control systems, comprising:

[0007] a circuit board;

[0008] an input interface arranged on the circuit board and used for connecting a card reader;

[0011] The further improvement of the communication control board for parallel compatibility of different access control systems is that the communication control board further comprises a setting switch arranged on the circuit board, and the setting switch has an open state and a closed state.

[0012] The control unit is connected with the setting switch, and the control unit is used for controlling the output of the first output interface and the second output interface according to the state of the setting switch.

[0013] The further improvement of the communication control board for parallel compatibility of different access control systems is that the communication control board further comprises a switch input interface arranged on the circuit board and used for connecting with a controller of one of the different access control systems.

[0014] The control unit is connected with the switch input interface, and the control unit is used for receiving the output signal of the controller of the connected access control system and controlling the output of the second output interface or the first output interface connected with another one of the different access control systems according to the received output signal.

[0015] The further improvement of the communication control board for parallel compatibility of different access control systems is that when the setting switch is in the closed state, the control unit is used for outputting the Weigand signal received from the input interface to the corresponding access control system through the first output interface or the second output interface connected with one of the different access control systems.

[0016] The control unit is further configured to store the Weigand signal received from the input interface in a cache space, and output the Weigand signal stored in the cache space to another access control system through the second output interface or the first output interface connected with the other access control system in the different access control systems according to the output signal of the corresponding access control system received from the switch quantity input interface.

[0017] The further improvement of the communication control board for parallel compatibility of different access control systems lies in that, when the setting switch is in the open state, the control unit is configured to output the Weigand signal received from the input interface to the corresponding access control system through the first output interface and the second output interface.

[0018] The application further provides a method for replacing an access control system by using the communication control board for parallel compatibility of different access control systems, which comprises the following steps:

[0020] connecting the first output interface of the provided communication control board with the Weigand input end of the controller in the original access control system;

[0021] connecting the second output interface of the provided communication control board with the Weigand input end of the controller in the new access control system;

[0022] controlling the output of the first output interface and the second output interface to enable the original access control system and the new access control system to run in parallel;

[0023] after the deployment of the new access control system is completed, connecting the output end of the card reader of the original access control system with the Weigand input end of the controller of the new access control system, thereby completing the replacement of the access control system.

[0024] The further improvement of the method for replacing an access control system lies in that, during the deployment of the new access control system, the Weigand signal output by the card reader received at the input interface is output to the original access control system and the new access control system through the first output interface and the second output interface, and the opening and closing of the door is controlled by the original access control system.

[0025] The further improvement of the method for replacing an access control system lies in that, during the trial operation stage of the new access control system, the Weigand signal output by the card reader received at the input interface is output to the new access control system through the second output interface, and the opening and closing of the door is controlled by the new access control system.

[0026] temporarily storing the Weigand signal received from the input interface;

[0027] receiving an output signal of a controller of the new access control system, and determining whether to output the Weigeng signal in the buffer space to the original access control system through the first output interface according to the received output signal.

[0028] The method for replacing the access control system is further improved in that if the received output signal of the controller of the new access control system is an opening signal, the temporarily stored Weigeng signal is output to the original access control system through the first output interface.

[0029] If the received output signal of the controller of the new access control system is a closing signal, the temporarily stored Weigeng signal is deleted.

[0030] The method for replacing the access control system is further improved in that after the replacement of the access control system is completed, the communication control board is removed and recycled.

[0031] The communication control board for parallel compatibility of different access control systems and the method for replacing the access control system have the following beneficial effects:

[0032] The communication control board of the application can be connected between the controller and the card reader of the original access control system, and the new access control system can be deployed on the premise of fully utilizing the original access control system, thereby avoiding interrupting normal business to cooperate with the reconstruction. By using the setting of the communication control board, the two access control systems can realize parallel compatibility, without the need for additional software development and IT equipment procurement, without the need to purchase the API interface of the access control system, and the cost can be reduced, the waste of resources can be eliminated, and the project cycle can be shortened.

[0033] The communication control board of the application realizes smooth transition of the new and old systems, gradually builds, can be fast or slow, and can be rolled back at each stage without any risk.

[0040] The present application will be further described below in conjunction with the drawings and specific examples.

[0041] Referring to Figure 3 The present application provides a communication control board for parallel compatibility of different access control systems and a method for replacing the access control system, which is used to solve the problem that the existing general access control system must be interrupted for reconstruction when replacing, and must be completed at one time, and cannot be carried out in stages and batches, and is also used to solve the problem of additional investment and waste existing in the existing construction management system. The communication control board of the present application can realize the parallel compatibility of two access control systems, so that the new access control system can be gradually deployed. The communication control board of the present application can make the old and new access control systems transition smoothly, can fully utilize the functions of the original access control system, reduce the one-time investment, and does not need to purchase API additionally, nor need additional software development, can reduce the cost of replacing the access control system, and also eliminates waste. The communication control board of the present application can make the old and new access control systems operate in parallel, can fully verify the operation of the new access control system, and after verification, the replacement of the new access control system is completed, so that the user has no risk in the process of replacing the access control system. The communication control board for parallel compatibility of different access control systems and the method for replacing the access control system of the present application will be described below in conjunction with the drawings.

[0042] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict.

[0043] Referring to Figure 3 , the structural diagram of the communication control board for parallel compatibility of different access control systems of the present application is shown. The structure of the communication control board for parallel compatibility of different access control systems of the present application will be described below in conjunction with Figure 3

[0044] As Figure 3 ​As shown, the communication control board for parallel compatibility of different access control systems of the present invention includes a circuit board (not shown in the figure), an input interface 21, a first output interface 22, a second output interface 23, and a control unit 24. The input interface 21, the first output interface 22, the second output interface 23, and the control unit 24 are all located on the circuit board. The control unit 24 is connected to the input interface 21, the first output interface 22, and the second output interface 23. The input interface 21 is used to connect to a card reader, and the Wiegand signal output by the card reader is transmitted to the control unit 24 through the input interface 21. The first output interface 22 and the second output interface 23 are used to connect to different access control systems respectively. When changing access control systems, the first output interface 22 can be connected to the original access control system, and the second output interface 23 can be connected to the new access control system. The control unit 24 is used to control the output of the first output interface 22 and the second output interface 23, thereby achieving parallel compatibility of different access control systems. Specifically, the control unit 24 can transmit the Wiegand signal transmitted by the input interface 21 to the corresponding access control system through the first output interface 22 and / or the second output interface 23.

[0045] Combination such as Figure 4 As shown, the communication control board 20 of the present invention can be applied during the replacement of old and new access control systems. The communication control board 20 connects the card reader 11 to the original access control controller 12 and the new access control controller 31. The control unit 24 can selectively transmit the Wiegand signal transmitted by the card reader 11 through the first output interface 22 and / or the second output interface 23 to the corresponding original access control controller 12 and the new access control controller 31 according to the deployment of the new access control controller 31. This realizes the parallelism and compatibility of the old and new access control systems. During the deployment of the new access control system, the old access control system can be fully utilized to realize access control management and operation, allowing for a smooth transition between the old and new systems and gradual construction, which can be fast or slow.

[0046] In one specific embodiment of the present invention, the communication control board of the present invention further includes a setting switch 25 disposed on the circuit board, the setting switch 25 having an open state and a closed state; the control unit 24 is connected to the setting switch 25, and the control unit 24 is used to control the output of the first output interface 22 and the second output interface 23 according to the state of the setting switch 25.

[0047] The control unit 24 has two operating modes, which can be selected according to the state of the setting switch 25. The control unit 24 includes a first operating mode and a second operating mode. When the setting switch 25 is in the open state, the control unit 24 enters the first operating mode; when the setting switch 25 is in the closed state, the control unit 24 enters the second operating mode. Thus, by opening and closing the setting switch 25, the control unit 24 can enter the corresponding operating mode.

[0048] Furthermore, it also includes a digital input interface 26 located on the circuit board, which is used to connect to the controller of one of the access control systems in a different access control system, in conjunction with... Figure 4 As shown, during the replacement of the old and new access control systems, the digital input interface 26 is connected to the new access control controller 31 of the new access control system, and the control unit 24 is connected to the digital input interface 26. The output signal of the new access control controller 31 can be transmitted to the control unit 24 through the digital input interface 26. The control unit 24 controls the output of the second output interface 23 or the first output interface 22 connected to another access control system in a different access control system according to the received output signal. If the new access control controller 31 is connected to the second output interface 23 and the original access control controller 12 is connected to the first output interface 22, then the control unit 24 controls the output of the first output interface 22 according to the received output signal of the new access control controller 31, that is, controls whether to transmit the Wiegand signal sent by the card reader 11 to the original access control controller 12.

[0049] Furthermore, when the setting switch 25 is in the closed state, the control unit 24 is in a second operating mode. In this second operating mode, the control unit 24 is used to output the Wiegand signal received from the input interface 21 to the corresponding access control system through the first output interface 22 or the second output interface 23 connected to one of the different access control systems. The control unit 24 is also used to store the Wiegand signal received from the input interface 21 into a buffer space, and then, based on the output signal of the corresponding access control system received from the switch input interface 26, determine whether to output the Wiegand signal stored in the buffer space to another access control system through the second output interface 23 or the first output interface 22 connected to another access control system.

[0050] by Figure 4 Taking the architecture diagram as an example, when the setting switch 25 is in the off state, the control unit 24 is used to transmit the Wiegand signal sent by the card reader 11 to the new access controller 31 through the second output interface 23. The control unit 24 is also used to store the Wiegand signal in the buffer space for temporary storage. The output signal of the new access controller 31 is transmitted to the control unit 24 through the switch input interface 26. The control unit 24 determines whether to transmit the Wiegand signal stored in the buffer space to the original access controller 12 through the first output interface 22 based on the output signal.

[0051] Furthermore, the digital input interface 26 is used to interface with the digital output of the access control controller. Digital output is a basic function of the access control controller and does not require additional development. The digital output of the access control controller is a "closed / open" signal given by the controller, that is, a signal used to control the opening and closing of the electric lock.

[0052] Further, when the output signal received by the control unit 24 through the on-off input interface 26 is a door opening signal or a signal allowing passage, the control unit 24 sends the Wiegand signal stored in the cache space to the original access controller 12 through the first output interface 22, and then deletes the Wiegand signal from the cache space; when the output signal received by the control unit 24 through the on-off input interface 26 is a door closing signal or a signal not allowing passage, the control unit 24 deletes the Wiegand signal stored in the cache space and does not send the Wiegand signal to the original access controller 12.

[0053] Further, when the setting switch 25 is in an open state, the control unit 24 is in a first working mode, in which the control unit 24 is configured to output the Wiegand signal received from the input interface 21 to the corresponding access control system through the first output interface 22 and the second output interface 22. Figure 4 In the embodiment shown, in the first working mode, the control unit 24 sends the Wiegand signal sent by the card reader 11 to the original access controller 12 and the new access controller 31 through the first output interface 22 and the second output interface 22, respectively, and at this time, the door is controlled by the original access controller 12.

[0054] In a specific embodiment of the present application, as shown in Figure 3 The communication control board of the present application further comprises a power supply interface 27 provided on the circuit board, which is configured to connect a direct current to the control unit 24 for power supply.

[0055] Preferably, the power supply interface 27 is connected to a power line, and the power supply is realized through the power line.

[0056] The circuit board of the present application is also called a circuit board or a PCB board, on which circuit lines are arranged to realize the connection of various interfaces, the setting switch and the control unit 24.

[0057] In a specific embodiment of the present application, the communication control board of the present application further comprises a housing, which encapsulates the circuit board and the control unit 24, and the input interface 21, the first output interface 22, the second output interface 23, the on-off input interface 26 and the setting switch 25 are provided on the housing, wherein the input interface 21 is connected to the card reader 11 through a signal transmission line, the first output interface 22 is connected to the Wiegand input end of the original access controller 12 through a signal transmission line, the second output interface 23 is connected to the Wiegand input end of the new access controller 31 through a signal transmission line, the on-off input interface 26 is connected to the on-off output end of the new access controller 31 through a signal transmission line, and the setting switch 25 is any one of a toggle switch, a button switch, a slide switch and a rotary switch.

[0058] The input interface 21 of the communication control board of the different access control system of the present application receives the output from the card reader, the standard output format of the card reader is Wiegand, and the ID or keyboard code of the card swiping is transmitted to the control unit 24; the first output interface 22 and the second output interface 23 are the output ports of the Wiegand signal, and are responsible for transmitting the Wiegand signal from the control unit 24 to the corresponding access controller; the on-off input interface 26 is connected to an on-off output of the access controller, the on-off output is the basic function of the access controller and does not need additional development, and the input is used to trigger the control unit 24 to judge whether to output data through the first output interface 22; the setting switch 25 has two states, which are an ON (closed) state and an OFF (open) state, and is used to set the mode of processing data of the control unit 24; the control unit 24 controls the Wiegand signal input from the input interface 21 to be output through the first output interface 22 and the second output interface 23 by the state of the setting switch 25 and the state of the on-off input interface 26.

[0059] The service logic of the communication control board of the present application has two kinds, when the setting switch is in the OFF state, the control unit 24 outputs the Wiegand signal received from the input interface 21 through the first output interface 22 and the second output interface 23; when the setting switch is in the ON state, the control unit 24 temporarily stores the Wiegand signal received from the input interface 21, and simultaneously outputs the Wiegand signal to the new access controller through the second output interface 23; the control unit 24 receives the output signal from the on-off input interface 26, and triggers the control unit 24 to simulate the rhythm of manual card swiping and manual keyboard input, and outputs the Wiegand signal to the original access controller through the first output interface 22, the control unit 24 temporarily stores the Wiegand signal, that is, temporarily stores the Wiegand signal received from the input interface 21, and clears after sending to the original access controller. Further, the control unit 24 can also judge the type of the output signal, if the output signal is a door opening signal or an allowed access signal, the Wiegand signal is output to the original access controller through the first output interface 22, if the output signal is a door closing signal or a disallowed access signal, the Wiegand signal is deleted and not sent to the original access controller.

[0060] As shown in Figure 4 and Figure 3 In use, the wiring method of the communication control board of the present application is that the card reader 11 is connected to the input interface 21 of the communication control board 20, the first output interface 22 of the communication control board 20 is connected to the Wiegand input end of the original access controller 12, the second output interface 23 of the communication control board 20 is connected to the Wiegand input end of the new access controller 31, and the on-off input interface 26 of the communication control board 20 is connected to a predefined output end of the new access controller 31.

[0061] When deploying a new access control system, the communication control board 20 of the present application can be used to set up the new access control system and the original access control system in parallel. During the deployment process, the original access control controller 12 and the original management software 13 of the original access control system control the opening and closing of the access control, i.e. the control connection between the original access control controller 12 and the switch actuator arranged at the door is not disconnected, i.e. the original access control system actually controls the opening and closing of the door to meet the access requirements. After the deployment of the new access control system is completed, when the new access control system needs to be run, the new access control controller 31 and the new management software 32 of the new access control system control the opening and closing of the access control, i.e. the new access control controller 31 is connected to the control of the switch actuator arranged at the door, and the control connection between the original access control controller 12 and the switch actuator arranged at the door is disconnected.

[0062] Further, when the communication control board 20 of the present application is used, the switch 25 is set to the OFF state, and the new access control system (including the new access control controller 31 and the new management software 32) can obtain the Weigeng signal of the card reader 11 together with the original access control controller 12 without additional development and API. In this stage, the original access control controller 12 implements the access control function, and this stage can be used to test whether the function of the new access control system meets the user's requirements and test the stability of the new access control system.

[0063] The communication control board 20 of the present application realizes the direct addition of a new access control system without changing the original access control system, so that the new and old access control systems can operate synchronously, and the original access control system can be fully utilized to reduce the one-time investment.

[0064] After the new access control system is completely deployed, the communication control board 20 of the present application can be removed, and the Weigeng input of the card reader 11 can be directly connected to the Weigeng input end of the new access control controller 31 to realize the smooth replacement of the equipment.

[0065] When the switch 25 is set to the ON state, the authority of the new access control system will be higher than that of the original access control system. When the new access control controller 31 receives the Weigeng signal and allows access, the output signal triggers the control unit 24 to allow the Weigeng signal to be transmitted to the original access control 12, otherwise, the output is not triggered. In this way, the need for additional purchase of API is eliminated, and the imported equipment and manufacturers who implement difficulties are mainly targeted.

[0066] The use process of the communication control board of the present application will be described below with an application example.

[0067] An enterprise is provided with 500 access control, and 100 access controllers are configured for every 5 access control in the 500 access control. When replacing a new access controller, the communication control board and the new access controller are deployed in sequence according to the planning design. In the process of accessing the new access controller, the original access controller is still in operation to ensure normal business uninterrupted. When the new access controller is put into trial operation, the original access controller can still receive the Weigeng signal of the card reader through logical design (although the original access controller does not participate in the actual access control). Thus, the examination of the new access controller can be realized. If the examination fails, it can be returned to the control state of the original access controller, so as to minimize the risk of replacing the access controller. After the examination is passed, the new access controller can be replaced for control, and the communication control board can be removed. In this example, the replacement of 100 new access controllers can be gradually constructed according to actual needs, which can be fast or slow, so that the new and old systems can be smoothly transitioned.

[0068] The application also provides a method for replacing an access control system by using a communication control board for parallel compatibility of different access control systems.

[0069] As shown in Figure 5 The method for replacing the access control system of the application comprises the following steps:

[0070] Step S101 is performed to provide a communication control board, and the input interface of the provided communication control board is connected with the output end of the card reader of the original access control system to receive the Weigeng signal output by the card reader. Then, step S102 is performed.

[0071] Step S102 is performed to connect the first output interface of the provided communication control board with the Weigeng input end of the controller in the original access control system. Then, step S103 is performed.

[0072] Step S103 is performed to connect the second output interface of the provided communication control board with the Weigeng input end of the controller in the new access control system. Then, step S104 is performed.

[0073] Step S104 is performed to control the output of the first output interface and the second output interface, so that the original access control system and the new access control system can run in parallel. Then, step S105 is performed.

[0074] Step S105 is performed to connect the output end of the card reader of the original access control system with the Weigeng input end of the controller of the new access control system after the deployment of the new access control system is completed, so as to complete the replacement of the access control system.

[0075] The replacement method of the access control system can be realized by a control unit, which can be a control unit on the communication control board of the application, has two working modes, which are a first working mode and a second working mode, and can also realize entering the corresponding working mode by setting the state of the switch.

[0076] In one specific embodiment of the application, in the process of deploying a new access control system, the Wiegand signals output by the card reader received at the input interface are output to the original access control system and the new access control system through the first output interface and the second output interface, and the opening and closing of the door is controlled by the original access control system. The above control step can be realized by the first working mode of the control unit.

[0077] In one specific embodiment of the application, in the trial operation stage of the new access control system, the Wiegand signals output by the card reader received at the input interface are output to the new access control system through the second output interface, and the opening and closing of the door is controlled by the new access control system.

[0078] The Wiegand signals received at the input interface are temporarily stored;

[0079] The output signal of the controller of the new access control system is received, and whether the Wiegand signals in the cache space are output to the original access control system through the first output interface is judged according to the received output signal. The above control step can be realized by the second working mode of the control unit.

[0080] Further, if the received output signal of the controller of the new access control system is an opening signal, the temporarily stored Wiegand signals are output to the original access control system through the first output interface;

[0081] If the received output signal of the controller of the new access control system is a closing signal, the temporarily stored Wiegand signals are deleted.

[0082] In one specific embodiment of the application, after the replacement of the access control system is completed, the communication control board is removed and recycled.

[0083] The communication control board for parallel compatibility of different access control systems and the method for replacing the access control system have the following beneficial effects:

[0084] The communication control board of the application can realize minimum cost equipment investment. After the original access control system is replaced by the new access control system, the communication control board can be recycled and reused in the next project, having the advantage of recycling.

[0085] The communication control board of the application does not need additional software development and IT equipment procurement in the process of replacing the original access control system with the new access control system, and there is no waste of resources. It can also shorten the project cycle.
