Each of the plurality of door locks 20 includes a first manual setting device 26 installed on the outer side 44B of the plurality of doors 44 and a second manual setting device 27 installed on the inner side 44A. A first handle 34A is mounted on the outer side 44B of the plurality of doors 44 and coupled with the latch driving device 22 , and a second handle 34B is mounted on the inner side 44A and coupled with the latch driving device 22 . In addition, the respective first and second manual setting devices 26, 27 of the plurality of door locks 20 may be a commercially available but not limited to commercially available key cylinder, and further correct The key releases the locked state of the first or second manual setting devices 26 and 27, so as to achieve the purpose of setting the locking mechanism 24 to a locked state or an unlocked state.

As shown in FIG. 1, the central control access control system 10 further includes a control device 33. The control device 33 includes a control module 33A, a main memory 36 electrically connected to the control module 33A, and a connector 38. The connector 38 may be an internal With an elongated slot for electrodes, the control module 33A of the regulating device 33 is electrically connected to the door lock control unit 28 of each door lock 20 . An unlocking device 40 is paired with the control device 33 to obtain control. The unlocking device 40 of the first embodiment of the present invention preferably uses an access card, the unlocking device 40 is used to control the control device 33, and the unlocking device 40 internally stores a corresponding unlocking identification information, the memory 29 of each door lock 20 internally stores a comparison identification information corresponding to the unlocking identification information possessed by the paired unlocking device 40 .

For convenience of explanation, assuming that the unlocking device 40 is inserted into the connector 38, the control module 33A reads the unlocking identification information in the unlocking device 40, and the control module 33A further compares and compares the identification information with the unlocking identification information. In a state consistent with the unlocking identification information, the control module 33A outputs an unlocking signal to the door lock control unit 28 of each door lock 20, and the door lock control unit 28 of each door lock 20 keeps the electric setting device 30 inactive, In this state, the locking mechanism 24 can be kept in the original state. For example, the locking mechanism 24 can be set to the unlocked state by using the correct release first manual setting device 26, and the electric setting device 30 is not working. If the first manual setting device 26 is used to set the locking mechanism 24 to the locked state, the locking mechanism 24 will be locked when the electric setting device 30 does not work. Keep it locked. In addition, when the control device 33 is set to the unlocked state, if the prompting device 32 of each door lock 20 is a luminous body, it will generate green light, and if the prompting device 32 is a buzzer or a horn, no sound will be generated.

When the control device 33 is set to the unlocked state, the door 44 is in the closed position, and the locking mechanism 24 of any one of the plurality of door locks 20 is set to the unlocked state, the first or second locking mechanism 24 of the door lock 20 is operated. The two handles 34A, 34B allow the interlocking latch driving device 22 to cause the latch head 23 to move from the latched position to the unlatched position, further allowing the door 44 corresponding to the door lock 20 to rotate from the closed position to the open position.

When the control device 33 is set to the unlocked state, the door 44 is in the closed position, and the locking mechanism 24 of any one of the plurality of door locks 20 is set to the locked state, the first or second operation of the door lock 20 is performed. The two handles 34A and 34B do not allow the interlocking latch driving device 22 to move the latch head 23 from the latching position to the unlatching position, and further do not allow the door 44 corresponding to the door lock 20 to rotate from the closed position to the open position.

Assuming that the control device 33 does not match the first and the unlocking identification information, the control module 33A outputs a prohibition signal to the door lock control unit 28 of each door lock 20 , so that the door lock control unit 28 of each door lock 20 The respective control electric setting devices 30 set the locking mechanism 24 originally set in the unlocked state to the locked state, or the locking mechanism 24 originally set in the locked state is held in the locked state. In such a case, As long as at least one of the plurality of doors 44 is in the closed position, at least one of the plurality of doors 44 in the closed position cannot be rotated from the closed position to the open position, and the control device 33 is set to the prohibited state At the same time, the prompting device 32 of each door lock 20 will generate prompting information to indicate that the control device 33 is set to the prohibited state, so that the user can also take the initiative to know that the control device 33 is set to the prohibited state. The movement of the plurality of doors 44 in the open position is set to the closed position, so that each door 44 cannot be rotated from the closed position to the open position.

Assuming that the control device 33 originally set in the unlocked state is to be set in the prohibited state, the unlocking device 40 inserted into the connector 38 of the control device 33 is unplugged, so that the control module 33A of the control device 33 cannot read the unlocking device 40 Therefore, the control device 33 is set to the prohibited state. When the control device 33 is set to the prohibited state, the control module 33A of the control device 3 outputs a prohibition signal to each door of the door lock 20. The lock control unit 28, so the door lock control unit 28 of each door lock 20 drives the electric setting device 30 to drive the locking mechanism 24 to switch from the unlocked state to the locked state, so that the latch of each door lock 20 drives The device 22 cannot work, and the first or second handle 34A, 34B cannot be used to drive the latch 23 to move from the latched position to the unlatched position. In such a situation, the prompting device 32 of each door lock 20 generates prompting information, In addition, if at least one of the plurality of doors 44 is in the closed position, the doors 44 cannot be rotated from the closed position to the open position. In addition, if at least one of the plurality of doors 44 is in the open position, the doors 44 can be rotated through the lock 20 of each door. The prompt information generated by the prompting device 32 actively turns the door 44 in the open position to the closed position, so that each door 44 can be kept in the closed position and cannot be rotated to the open position until the control device 33 is set to the unlocked state or The user uses the correct key until the locking mechanism 24 is switched to the unlocked state by the first or second manual setting devices 26 and 27 .

Suppose that the control device 33 that is originally in the prohibited state is to be set to the unlocked state, the unlocking device 40 that is paired with the control device 33 and has the control right is inserted into the connector 38, and the control device 33 compares and compares the identification information with the unlocking identification. If the information matches, it will be set to the unlocked state. In this way, the control module 33A outputs an unlocking signal to each door lock 20, so that each door lock 20 will release the prompt device 32 to work, and the locking mechanism 24 of each door lock 20 will work. The locking mechanism 24 can still be set to the unlocked state through the first or second manual setting devices 26 and 27 by using the correct key according to actual needs.

Assuming that when the control device 33 is set to the prohibited state, the unlocking device 40 separated from the control device 33 is allowed to be held by the administrator and move arbitrarily to the vicinity of any one of the plurality of door locks 20. When the unlocking device 40 is used with the The reading device 31 of the approaching door lock 20 is electrically connected or sensed, so that the door lock control unit 28 reads the unlocking identification information in the unlocking device 40 and compares it with the comparison identification information stored in the memory 29. When the identification information is matched, the door lock control unit 28 drives the electric setting device 30 to set the locking mechanism 24 to the unlocked state, and further allows the first handle 34A to drive the latch driving device 22 so that the latch head 23 is driven by the latch. The position is moved to the unlocking position. In the case where the unlocking identification information does not match the comparison identification information, the door lock control unit 28 drives the electric setting device 30 to switch the unlocking mechanism 24 to the locked state, and further does not allow the use of the first handle 34A Actuating the latch driving device 22 causes the latch head 23 to move from the latching position to the unlatching position.

In addition to the central control access control system 10 of the first embodiment shown in FIGS. 1 and 2 , other changes can also be made, as shown in FIGS. 3 and 4 are the central control access control system 10 of the second embodiment of the present invention. , compared with the central control access control system 10 of the first embodiment, each door lock 20 of the central control access control system 10 of the second embodiment of the present invention further includes a first wireless device electrically connected to the door lock control unit 28. The transmission module 35, the control device 33 further includes a second wireless transmission module 42 electrically connected to the control module 33A, in addition, the control device 33 is not provided with the connector 38, the control device 33 of the second embodiment uses the control module 33A. A third wireless transmission module 43 replaces the connector 38 described in the first embodiment. In this state, the unlocking device 40 can be an access control card and a device other than the access card. For example, the unlocking device 40 can be a manager's mobile phone. , a tablet computer, a personal computer, a remote control, and other devices that allow communication with the third wireless transmission module 43 . In addition, the first wireless transmission module 35 of each door lock 20 is connected to the second wireless transmission module 42 of the control device 33 respectively, so the control device 33 and each door lock 20 do not need to be electrically connected by any wires. The prohibition signal or release signal of the lock can be transmitted to the first wireless transmission module 35 of each door lock 20 through the second wireless transmission module 42 .

Assuming that the access control card is used as the unlocking device 40 (as shown in FIG. 4 ), when the access control card is located within the communication range of the third wireless transmission module 43, the control device 33 is set to the unlocking state, and when the access control card is located in the third wireless transmission module 43, the control device 33 is set to the unlocking state. In a state outside the communication range of the three wireless transmission modules 43, the control device 33 is set to a prohibited state. When the control device 33 is set to the prohibited state, the access control card is allowed to approach the door lock 20 on the door 44 to be opened, so that the first wireless transmission module 35 of the door lock 20 can read the unlocking in the access control card Identification information, the door lock control unit 28 of the door lock 20 compares the obtained unlock identification information with the comparison identification information in the memory 29, if the door lock control unit 28 of the door lock 20 compares the unlock identification information with the comparison identification information. If the identification information does not match, the locking mechanism 24 of the door lock 20 remains in the original state (one of the locked state or the unlocked state). If the door lock control unit 28 of the door lock 20 compares the unlocking identification information with the comparison If the identification information matches, the locking mechanism 24 of the door lock 20 is set to the unlocked state by the electric setting device 30, thus allowing the user holding the access control card to turn the door 44 from the closed position to the open position.

Assuming that the administrator's mobile phone is used as the unlocking device 40 (as shown in FIG. 5 ), the respective memory 29 of each door lock 20 stores an exclusive piece of hardware identification information, and the memory 36 of the control device 33 stores each door lock 20 hardware identification information, the administrator's mobile phone can connect with the third wireless transmission module 43 through a management software to operate the control device 33, that is to say, when the control device 33 is set to the unlocked state, the administrator's mobile phone is allowed. The mobile phone usage management software sends a designated prohibition signal to a specific at least one of the plurality of door locks 20 through the control device (the control device is not set to the prohibition state). In detail, when the manager's mobile phone connects with the control device 33 and executes the management software, the manager's mobile phone obtains all the hardware identification information of each door lock 20 in the main memory 36 of the control device 33, thus allowing the manager to The mobile phone selects to send a designated prohibition signal to a specific at least one of the plurality of door locks 20 via the control device 33, and the designated prohibition signal sent by the control device 20 in this state further includes the hardware of the specific door lock 20 selected by the administrator Identification information (there can be multiple pieces of hardware identification information), so the control device 33 sends out a designated prohibition signal that will be received by all the door locks 20, but each of the plurality of door locks 20 compares the received hardware identification information of the designated prohibition signal with that of the designated prohibition signal. Whether the hardware identification information stored in the memory 29 is the same, if at least one of the plurality of door locks 20 has the hardware identification information in the comparison prohibition signal and the hardware identification information in the memory 29 different, then the door of the door lock 20 The lock control unit 28 does not drive the electric setting device 30, so that the locking mechanism 24 of the door lock 20 remains in the original state (one of the locked or unlocked states), if at least one of the plurality of door locks 20 is compared The hardware identification information in the prohibition signal is the same as the hardware identification information in the memory 29, then the door lock control unit 28 of the door lock 20 drives the electric setting device 30 so that the locking mechanism 24 is set to the locked state, and the door is further installed. The door 44 of the lock 20 is not allowed to rotate from the closed position to the open position.
