[0037] The input terminal of the POE power receiving module 12 is used for electrically connecting to the POE network switch 18;

[0038] The main controller 11, the POE power receiving module 12, the voltage conversion module 13, the reader module 14, the button module 15, and the switch module 16 are respectively arranged on the PCB main board 17;

[0039] The input terminal of the reader module 14 is used for receiving the ID information read by the reader 19 and transmitting the ID information to the main controller 11;

[0040] The input terminal of the button module 15 is used for receiving the trigger signal of the door button 20 and transmitting the trigger signal to the main controller 11;

[0041] The output terminal of the switch module 16 is used for supplying power to the access control electric lock 21 through the voltage conversion module 13 under the control of the main controller 11.

[0042] In this embodiment, the main controller 11 can be implemented by a conventional single-chip microcomputer. The POE power receiving module 12 can adopt a conventional POE network interface to realize the integration of power supply and communication. The input terminal of the POE power receiving module 12 and the POE network switch 18 are connected by a network cable. The voltage conversion module 13 can adopt a conventional buck circuit, such as a buck circuit based on the principle of resistor voltage division.

[0044] In this embodiment, the through hole 171 can be used to fix the front access control controller 100 by means of screws or the like. For example, the front access control controller 100 can be fixed in the corresponding installation box by passing screws through the through hole 171, so as to improve the stability of the front access control controller 100 and prevent abnormal connection of related lines or poor contact of connection ports caused by unstable installation.

[0045] Further, the POE power receiving module 12 uses an Ethernet POE access port.

[0046] In this embodiment, the POE power receiving module 12 can adopt a conventional Ethernet POE access port, that is, a conventional network port with POE power supply function.

[0047] The present utility model also provides an access control system, which includes at least one control point unit 200, a POE network switch 18, and a server 22;

[0048] The control point unit 200 includes an access control electric lock 21, a reader 19, an exit button 20, and the front access control controller 100 as described above;

[0049] The access control electric lock 21 is electrically connected to the output end of the switch module 16 in the front access control controller 100;

[0050] The reader 19 is electrically connected to the input end of the reader module 14 in the front access control controller 100;

[0051] The exit button 20 is electrically connected to the input end of the button module 15 in the front access control controller 100;

[0052] The input end of the POE power receiving module 12 in the front access control controller 100 is electrically connected to the POE network switch 18;

[0053] The POE network switch 18 is electrically connected to the server 22.

[0054] In this embodiment, the number of control point units 200 is n (such as Figure 3 ), where n is an integer greater than or equal to 1. Each control point unit 200 is powered by the POE network switch 18. The front access control controller 100 adopts a miniaturized structure design and can be installed nearby in the wall on the back of the installation surface where the exit button 20 is located to achieve a concealed installation. The access control electric lock 21, the reader 19, and the exit button 20 are connected to the front access control controller 100 by short-distance local wiring, which simplifies the lines, saves cables, and can effectively reduce the implementation cost.

[0055] In a specific embodiment, the door release button 20 is installed indoors, the reader 19 is installed outdoors, the access control electric lock 21 is associated with the door to achieve the closed and open states, the front access control controller 100 is installed in the installation box, and the installation box is hidden in the back wall at the position where the door release button 20 is located. The POE network switch 18 is installed in the weak current well, and the server 22 is installed in the control center, i.e., the computer room. The POE network switch 18 is respectively connected to the front access control controller 100 and the server 22 through network cables. The POE power receiving module 12 applies for power supply from the POE network switch 18 and starts running after completion. Assume that the reader 19 uses an ID reader, the button module 15 uses a conventional high-level or low-level generation circuit, and the switch module 16 can be a conventional relay. When the user approaches the reader 19 with an ID access control card, the reader 19 reads the ID information and transmits it to the reader module 14. The reader module 14 transmits the ID information to the main controller 11. The main controller 11 transmits the ID information to the server 22 through the POE power receiving module 12 and the POE network switch 18 for permission verification. When the verified permission is valid, the server 22 sends an open door instruction to the main controller 11. The main controller 11 sends a pulse signal to the switch module 16 according to the open door instruction. The switch module 16 performs a power-off operation for a preset time (such as 3 s) under the action of the pulse signal and re-powers on after the preset time. When the switch module 16 is in the power-off operation period, the access control electric lock 21 is unlocked and the user can perform the door opening action. When the verified permission is invalid, the server 22 does not send relevant instructions to the main controller 11, only records the relevant permission verification records in the server 22, the switch module 16 does not act, and the voltage conversion module 13 maintains the state of supplying power to the access control electric lock 21. The access control electric lock 21 is in the locked state and the user cannot perform the door opening action. When the user presses the door release button 20 indoors to perform the door opening action, the door release button 20 transmits a trigger signal to the button module 15. The button module 15 sends a level change signal (from the original high-level state to the low-level state or from the original low-level state to the high-level state) to the main controller 11 under the action of the trigger signal. The main controller 11 sends a pulse signal to the switch module 16 under the action of the level change signal. The switch module 16 performs a power-off operation for a preset time (such as 3 s) under the action of the pulse signal and re-powers on after the preset time. The main controller 11 can also transmit the corresponding operation data of sending the pulse signal to the switch module 16 to the server 22 for storage.

[0056] Optionally, the door release button 20 installed indoors can be replaced by a reader 19, that is, one reader 19 is installed indoors and outdoors respectively. Both readers 19 are respectively connected to the reader module 14, and the door release button 20 is no longer installed. At this time, permission verification is also required through the server 22 when going out.

[0057] Further, the reader 19 and the reader module 14 are electrically connected through the RS485 communication method.

[0058] In this embodiment, the reader 19 and the reader module 14 are connected by the RS485 communication method, and a separate power line is also connected between the two. The reader module 14 provides the voltage obtained from the voltage conversion module 13 to the reader 19 through this power line.

[0059] Further, the connection line between the access control electric lock 21 and the switch module 16 is less than 5 meters.

[0060] Further, the access control electric lock 21 is any one of an electric control magnetic lock, an electric control latch, and an electric control bolt lock.

[0061] The above embodiments should not limit the present invention in any way. All technical solutions obtained by using equivalent replacements or equivalent conversions fall within the protection scope of the present invention.
