Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The technical solution of the present invention is further explained below with reference to specific embodiments.
As shown in fig. 1, the present embodiment provides an intelligent door lock with fingerprint identification, card swiping identification, and face identification functions, including a lock body, a raspberry pi core board, a touch display screen, a fingerprint module, a card swiping module, a camera, an unlocking motor, and a wireless communication module; the lock body is connected with an unlocking motor, and the raspberry group core board sends a signal to control the unlocking motor to rotate so as to control the lock body to be opened or closed; the touch display screen is connected with the raspberry group core board through an HDMI (high-definition multimedia interface); the fingerprint module is connected with the raspberry group core board through a USART interface; the card swiping module is connected with the raspberry pi core board through the SPI interface; the camera module is connected with the raspberry group core board through the USB interface, and the wireless communication module is further connected with the camera module.
The device in this embodiment is selected as follows: the raspberry group core board adopts raspberry group 4B, the camera module adopts a VGA camera, the fingerprint identification module adopts an AS608 optical fingerprint module, the card swiping module adopts an RC522 radio frequency identification module, and the unlocking motor adopts an MG995 steering engine.
The embodiment has three unlocking modes, which are respectively as follows:
mode (1) face recognition authentication:
and starting a camera to detect a real-time picture, and if a face image is obtained, transmitting image information to the raspberry group core board.
The raspberry group core board processes the face image, calculates and obtains face information, and compares the face information with face information of registered users in the raspberry group core board one by one.
After the contrast is successful, the raspberry group core board sends a control signal to the unlocking motor to unlock the lock body.
If the comparison is not successful, the image can be sent to the mobile phone end through the wireless communication module, a host holding the mobile phone can judge whether the mobile phone is a mature person through the camera, and if the mobile phone is the mature person, the lock body is opened by sending a control signal to the unlocking motor.
Mode (2) fingerprint identification and authentication:
when the user verifies, the user needs to aim at the sensing area of the fingerprint module with the finger, and the fingerprint module collects the living body fingerprint by using the photoelectric conversion equipment and the image processing technology.
And reading the characteristic information after acquiring the image, generating a characteristic instruction, comparing the characteristic instruction with the fingerprint contained in the fingerprint module, and returning the ID of the fingerprint template after matching successfully.
And sending the ID of the fingerprint template to a raspberry group core board to be matched with the registered fingerprint ID.
If the identification is successful, the raspberry group core board sends a control signal to the unlocking motor to unlock the lock body.
Mode (3) IC card identification and authentication:
when the user verifies, the user needs to put the IC card in a designated identification area, and the corresponding module can read the information of the IC card.
And sending the acquired IC card information to a raspberry group core board, matching the IC card information with the registered IC card information, if the search is successful, verifying the IC card information, and sending a control signal to an unlocking motor by the raspberry group core board to unlock the lock body.
