[0038] In one embodiment of the present application

[0039] like Figure 1 As shown: This is the main components and control relationship diagram of the indoor door lock controller of this application. The internal circuit board mainly includes the door lock MCU, which interacts with the digital touch buttons, RFID card reader module and fingerprint module. The multi-language storage chip stores language information of multiple countries, providing rich language information storage for the door lock MCU. The door lock MCU also controls the speaker and lights through the speaker interface and light indication module, guiding the user with sound and light signals.

[0040] like Figure 2-6 As shown, the indoor door lock controller of the present invention is designed as follows: the main frame is the door lock box body 1, and all electrical components are arranged in the door lock box body 1.

[0041] like Figure 3-Figure 5As shown, the door lock box body 1 of the present invention includes a front touch panel 11 and a rear cover panel 12, and a storage space 10 is formed between the front touch panel 11 and the rear cover panel 12. A control main board 13 is arranged in the storage space 10, and the control main board 13 is arranged on the back of the front touch panel 11. The control main board 13 and the front touch panel 11 are combined into the front and back of a board. The front is used to input digital signals through digital buttons, and the back is the control main board 13, on which various components are arranged.

[0042] The control motherboard 13 is the main circuit PCB board of this device, and the door lock MCU is set on the control motherboard 13. The door lock MCU is a microprocessor that can perform simple processing based on the input signal and output corresponding control signals, such as opening and closing the lock, issuing voice prompts, and controlling the brightness of the lights.

[0043] like Figure 2 As described, a digital touch button 2 is provided on the front touch panel 11, and the digital touch button 2 communicates with the door lock MCU through the SPI interface. The digital touch button 2 can be used to set and select the language mode, or the digital password can be used as the unlocking password to directly open and close the door lock.

[0044] like Figure 3-Figure 4 As shown, threaded holes 120 are provided on both the front touch panel 11 and the rear cover 12. The front touch panel 11 and the rear cover 12 are connected by screws, which are threadedly connected to the front touch panel 11 and the rear cover 12 in turn through the threaded holes 120. Four mounting plates 111 are provided on the side wall of the front touch panel 11. Each mounting plate 111 has a connection hole 110. Other screws are passed through the connection holes 110 to fix the entire indoor door lock controller in a set position.

[0045] like Figure 3-Figure 4 As shown, a clamping plate 121 is provided on the rear cover 12. The clamping plate 121 is used to clamp the wires to prevent the wires from becoming loose and to fix them.

[0046] like Figure 5-Figure 6 As shown, a multi-language storage chip 4, a voice playback module 5 and a light indication module 6 are provided on the control mainboard 13. The voice playback module 5 is connected to a speaker interface 131, and the speaker interface 131 is connected to a speaker device, which plays the corresponding voice prompts.

[0047] like Figure 5 As shown, the present invention has two main power supply modes. The first is through the power main line interface 132 connected to the control motherboard 13. The power main line interface 132 is connected to an external power source for supplying power to the control motherboard 13. It is used when the conventional main power supply is energized and is the main mode of use.

[0048] The second method is to control the USB interface 133 provided on the main board 13. After the main power is cut off, an external charger, such as a power bank, is connected through the USB interface 133 to temporarily power on and unlock the door.

[0049] like Figure 5-Figure 6 As shown, in addition to directly unlocking the door through the digital touch button 2, the control main board 13 is also provided with a fingerprint module interface 3.

[0050] In addition to the above unlocking methods, the control mainboard 13 of the present invention is also provided with an RFID card reader module 8, which communicates with the door lock MCU via an SPI interface and can be unlocked by swiping a password card.

[0051] In order to prevent the door lock from being damaged and forced to open, an anti-dismantling detection switch 7 is also provided on the inner side of the rear cover 12. When the anti-dismantling detection switch 7 detects continuous vibration, it sends an alarm signal to the control main board 13. The anti-dismantling detection switch 7 can detect abnormal conditions and alarm in time.

[0052] like Figure 5 As shown, a motor interface 134 is also provided on the control main board 13, and the motor interface 134 is used to connect the control motor of the door lock. When the control main board 13 recognizes that the password is correct, a motor control signal is sent through the motor interface 134 to control unlocking.

[0053] A workflow for this application:

[0054] Language selection is performed through the digital touch button. At the same time, the light indication module and voice playback module guide and remind the user. The light feedback of the unlocking status improves the convenience of user unlocking. Alternatively, the user can directly set the digital password in the digital touch button to unlock, or unlock with the fingerprint module or RFID card reader module. Multiple unlocking methods are parallel to improve the convenience of unlocking. The security of the lock body is detected through the anti-dismantling detection switch to prevent the door lock from being violently dismantled and timely alarm to remind the user.

[0055] The various technical features of the above-described embodiments can be combined arbitrarily, and the execution order of the method steps is not restricted.
