The specific embodiments and working principles of the present invention will be further described in detail below with reference to the drawings.

As shown in FIG. 1, a Bluetooth access control system 100 based on remote authorization of a smart terminal includes a door lock mechanism 1 connected to a control circuit 2, which includes a controller 3 and a drive mode. a group 4 and a power module 5, wherein the controller 3 is connected with a Bluetooth module 31, a matching button 32, a wake button 33, a delete button 34, an LED indicating circuit 35, a USB key interface 36, and an EEROM memory 37. The controller 3 performs key matching with the smart terminal through the Bluetooth module 31, and the smart terminal with the key matching as the authorized user terminal 6 can remotely transmit the unlocking password to the third-party user terminal 7, and the controller 3 passes The Bluetooth module 31 implements unlock authentication with the authorized user terminal 6 or the third party user terminal 7.

In this embodiment, the circuit schematic of the Bluetooth module 31 is as shown in FIG. 2, and each control signal is connected to the BUS bus. The circuit schematic of the control circuit 2 and the driving module is shown in FIG. Bit microcontroller The TM57PA10A acts as a controller to control the forward and reverse rotation of the door lock mechanism by controlling the on/off state of the switch tubes Q1, Q2, Q4 and Q5, thereby realizing the locking and unlocking of the access control system. It can also be seen from Fig. 3 that the control is controlled. The EEROM memory connected to the device is M24C02. The P1 interface in the figure is used as the USB key interface. The matching button, wake-up button and delete button in the system are respectively connected in series with the BUS bus by a push button switch. Between, for providing a button pulse signal, the controller 3 performs a corresponding control flow according to various button pulse signals.

The specific control method of the foregoing control system in the implementation of the access control management process mainly includes a key matching step and an unlocking authentication step; as shown in FIGS. 1 and 4, the key matching step includes: S11: in the USB key interface 36 Inserting a USB key module, the USB key module is mainly used to generate corresponding key information, and each set of access control system corresponds to a set of USB key module as a corresponding electronic key; S12: triggering a key by a matching button a matching process, in the key matching step, the controller 3 further controls the LED indicating circuit 35 to output a key matching indication information, and after pressing the matching button, the red indicator light and the green indicator light on the controller 3 flash alternately. , indicating that key matching can be performed, the user can perform step S13 through the application software of the smart terminal; S13: the smart terminal establishes a Bluetooth connection with the controller 3, and for this example, after performing step S12, the controller 3 is Wake up, the smart terminal can establish a Bluetooth connection with the controller 3, in the actual process, when the smart terminal turns on the Bluetooth function, it can automatically search for the attached Bluetooth device. Now Bluetooth connection; S14: Bluetooth smart terminal device information, unlock code And the mobile phone number is simultaneously sent to the controller 3; in fact, the user only needs to set the unlocking password and the mobile phone number on the application software, and the information sent by the smart terminal to the controller 3 will include its own Bluetooth device information, where the Bluetooth device is located. The information is usually the physical address code of the hardware of the Bluetooth device automatically extracted by the application software. In order to facilitate management, some information about the access control system, such as the type of the door lock, the position of the door lock, etc., are also designed on the application software; S15: The controller 3 saves the Bluetooth device information, the unlock password, and the mobile phone number as the key information of the authorized user terminal 6 to the EEROM memory 37, and the smart terminal that matches the key is the authorized user terminal 6; After that, the smart terminal can implement unlock authentication, and can also perform remote authorization to the third-party user terminal 7.

The unlocking authentication step designed by the present invention is as shown in FIG. 1 and FIG. 5, and specifically includes: S21: waking up the controller 3 in a sleep state by using the wake button 33; In order to save power, the controller 3 and the Bluetooth module 31 are usually in a sleep state, and when the wake button 33 gives a trigger signal, the controller 3 and the Bluetooth module 31 can resume operation; S22: when the controller 3 and the Bluetooth module After the power-on is restored, the smart terminal can establish a Bluetooth connection with the controller 3; S23: the smart terminal can transmit the Bluetooth device information to the controller 3 through the Bluetooth communication by pressing the virtual button on the application software; S24: controller 3 determining whether the received Bluetooth device information belongs to the Bluetooth device information of the authorized user terminal 6; if yes, it is determined to be The user terminal 6 outputs the door lock unlocking signal; if not, it proceeds to S25; S25: the controller 3 sends a prompt message to the smart terminal prompting to input the unlocking password; S26: the smart terminal unlocks the password and the last time the mobile phone is communicated The number is sent to the controller 3; S27: the controller 3 determines whether the received unlock password and the mobile phone number belong to the unlocking password and the mobile phone number of the authorized user terminal 6; if yes, the remote authorized third-party user terminal 7 The door lock unlock signal is output; if not, it is determined to be illegally unlocked and returns to the sleep state.

In the unlocking authentication step, the controller 3 further controls the LED indicating circuit 35 to output the unlocking instruction information, for example, the unlocking authentication is successful, and the controller 3 controls the green LED in the LED indicating circuit 35 to blink. If the unlocking is unsuccessful, The red LED flashes and the corresponding alarm signal can be output via the buzzer.

Based on the above method, it can be found that the matching user terminal is very convenient when unlocking the authentication, and executing the virtual button on the application software to output the Bluetooth device information can be quickly unlocked, and for the third-party user terminal 7, the Bluetooth device information authentication If the interface is unsuccessful, the interface for unlocking the password is automatically popped up, and the application software automatically extracts the mobile phone number of the last communication of the smart terminal, and the authorized user can remotely notify the third-party user terminal 7 of the unlock password, and then connect by voice call or short message. The remote communication is established, and the controller 3 determines whether the unlocking password and the mobile phone number of the last communication are the same as the unlocking password and the mobile phone number preset by the authorized user terminal 6, thereby performing unlocking authentication.

Only when the authorized user terminal 6 informs the unlocking password of the third The party user, at the same time, has recently established a communication connection with a third-party user to enable the third-party user terminal 7 to be correctly unlocked, thereby ensuring the security performance of the system, and the information that the third-party user needs to input only protects the unlock password, and is also very useful. Convenience.

In order to meet certain special requirements, the control method of the system further includes the step of deleting the matching information. When the delete button 34 is pressed, the controller 3 deletes the key information of all authorized user terminals 6 on the EEROM memory 37, which is convenient. The user updates the key matching information.

The above embodiments of the present invention are provided for convenience of explanation only. When the meaning of the case cannot be limited, the various transformation designs according to the scope of the listed patent application should be included in the patent scope of the present application.
