The 125kHz carrier circuit is connected to both the MCU module and the ID card reader antenna. Through the cooperation of the 125kHz carrier circuit and the ID card reader antenna, the ID card information can be effectively activated and read.

[0025] The IC card reader circuit includes a dedicated IC card processing chip and an IC card reader antenna. The IC card reader antenna corresponds to the IC card reading area. The dedicated IC card processing chip is connected to both the MCU module and the IC card reader antenna, and the dedicated IC card processing chip and the MCU module are connected via SPI communication. The dedicated IC card processing chip can efficiently parse the signals returned by the IC card and quickly transmit the data to the MCU module via SPI communication.

[0026] The Dallas card reader circuit includes an external Dallas reader interface and a Dallas reader connector. The external Dallas reader interface corresponds to position 3 of the Dallas identification zone and is connected to the MCU module via the Dallas reader connector.

[0030] Working principle: When using an ID card for authentication, the ID card is brought close to the ID card reader area. The MCU module sends a signal through the ID card reader antenna via a 125KHz carrier circuit to activate the ID card. The ID card sends its own card number information. The ID card reader circuit decodes the signal and transmits it to the MCU module. The MCU module processes the information. If the verification is successful, it controls the relay to open the access control and emits a buzzer sound, while indicator light 4 indicates accordingly. When using an IC card, the IC card is brought close to the IC card reader area. The MCU module sends a signal through the IC card reader antenna via a dedicated IC card processing chip to activate the IC card. The IC card returns information, which is parsed by the dedicated IC card processing chip and transmitted to the MCU module via SPI communication. The MCU module processes the information and performs the corresponding operation. When using a Dallas card, it is connected to the external Dallas reader interface in the Dallas identification area 3. The Dallas card is powered on and sends information, which is transmitted to the MCU module via the Dallas reader connector. After verification, the corresponding action is executed. In addition, users can also verify their identity via fingerprint recognition area 7 or by entering a password via the password touch button 2. Administrators can remotely set up and manage the access control machine through an APP connected to the WIFI module. The clock chip provides an accurate time reference for the access control machine, and the power module provides stable power to all components.
