Abstract

A door access control system ( 9 ) with a cloud function includes a door lock ( 10 ) mounted to a door ( 435 ). A door lock controller ( 611 ) is mounted in the door ( 435 ) and is electrically connected to the door lock ( 10 ). A wireless charging device ( 511 ) is electrically connected to the door lock controller ( 611 ). A main control unit ( 659 ) is provided for operating the door lock controller ( 611 ). The door access control system ( 9 ) further includes a cloud server ( 711 ) that can be connected to the door lock controller ( 611 ). The main control unit ( 659 ) can be connected to and log in the cloud server ( 711 ).

First claim

The invention claimed is:

1. A door access control system comprising:
an active door opening unit including an ultrahigh frequency (UHF) radio frequency identification (RFID) module, a battery electrically connected to the UHF RFID module, and a low frequency (LF) reception module, with the UHF RFID module including a first memory storing an access identification number;
a radio frequency identification (RFID) communication controllable device configured to install a door access control program capable of performing a user deletion function and a cloud login function;
a door lock including a latch head slideable between a latching position and an unlatching position, with the door lock further including a locking mechanism operably connected to the latch head, with the door lock adapted to be mounted to a door;
a control module connected to the locking mechanism and controlling the locking mechanism to be in a locking state preventing movement of the latch head from the latching position to the unlatching position or an unlocking state permitting movement of the latch head from the latching position to the unlatching position;
a power supply unit electrically connected to the control module;
a main memory electrically connected to the control module, with the main memory storing a first access list consisting of at least one authorized access identification number;
a passive induction module electrically connected to the control module, with the control module configured for receiving the access identification number of the UHF RFID module via the passive induction module;

a low frequency (LF) transmission module electrically connected to the control module, with the control module controlling the power supply unit to supply electricity to the LF transmission module, with the LF transmission module setting a received signal strength indication value to decide a communication range of the LF transmission module;
a cloud server including a storage device storing a second access list consisting of at least one authorized door access identification number; and
a wireless transmission module electrically connected to the control module, with the control module configured to be connected to the cloud server via the wireless transmission module, permitting the cloud server to update the first access list of the main memory, with the RFID communication controllable device configured to be connected to the cloud server,
wherein when the RFID communication controllable device executes the cloud login function of the door access control program, the RFID communication controllable device is permitted to be connected to the cloud server and is permitted to log in the cloud server by inputting an account and a code,
wherein when the RFID communication controllable device does not execute the cloud login function of the door access control program, the RFID communication controllable device is prevented from being connected to the cloud server,
wherein when the RFID communication controllable device logs in the cloud server, the RFID communication controllable device is permitted to perform the user deletion function or the cloud login function to change a content in the second access list of the cloud server, and the cloud server updates the first access list of the main memory according to the second access list,

wherein when at least one of the account and the code inputted by the RFID communication controllable device is incorrect, the RFID communication controllable device is prevented from logging in the cloud server, preventing the RFID communication controllable device to perform the user deletion function and the cloud login function, and the cloud server is prevented from updating the first access list of the main memory,
wherein when the active door opening unit is outside of the communication range of the LF transmission module, operation of the UHF RFID module is prevented,

wherein when the active door opening unit is within the communication range of the LF transmission module, the LF reception module activates the UHF RFID module to operate by using electricity of the battery,
wherein when the UHF RFID module operates, the control module uses the passive induction module to receive the door access identification number of the UHF RFID module,

wherein when the control module identifies that the access identification number of the UHF RFID module is identical to one of the at least one authorized access identification number of the first access list of the main memory, the control module is permitted to set the locking mechanism in the unlocking state, and
wherein when the control module identifies that the access identification number of the UHF RFID module is not identical to any one of the at least one authorized access identification number of the first access list of the main memory, the control module sets the locking mechanism in the locking state.

2. The door access control system as claimed in claim 1 , with the active door opening unit further including a high frequency (HF) radio frequency identification module having a second memory storing an access identification number, with the door access control program of the RFID communication controllable device further including a third access list and a user adding function, with the door access control system further comprising:
an active induction module electrically connected to the control module, with the control module configured for driving the active induction module to read the access identification number of the HF RFID module,
with the RFID communication controllable device executing the user adding function, when the active door opening unit is within the communication range of the RFID communication controllable device, the RFID communication controllable device obtains the access identification number of the HF RFID module, adds the access identification number of the HF RFID module into the third access list of the RFID communication controllable device, sets the access identification number of the HF RFID module as an authorized access identification number,
wherein when the RFID communication controllable device obtains the access identification number of the HF RFID module and logs in the cloud server, the RFID communication controllable device adds the access identification number of the HF RFID module into the second access list of the cloud server by executing the user adding function, granting door access authority to the HF RFID module,

wherein when the battery is unable to provide electricity to the UHF RFID module for operation and when the active door opening unit is within the communication range of the active induction module, the control module drives the active induction module to read the access identification number of the HF RFID module,
wherein when the battery is unable to provide electricity to the UHF RFID module for operation and when the active door opening unit is outside of the communication range of the active induction module, the control module is prevented from driving the active induction module to read the access identification number of the HF RFID module,
wherein when the control module identifies that the access identification number of the HF RFID module is identical to one of the at least one authorized access identification number of the first access list of the main memory, the control module sets the locking mechanism in the unlocking state, and
wherein when the control module identifies that the access identification number of the HF RFID module is not identical to any one of the at least one authorized access identification number of the first access list of the main memory, the control module sets the locking mechanism in the locking state.
