Abstract
As society continues to evolve, the demand for access control systems has been steadily increasing. Traditional mechanical locks are gradually unable to meet the modern society’s requirements for convenient, secure, and intelligent door locking systems. Consequently, the emergence of a multi-mode unlocking control system based on a single-chip microcontroller has arisen to fulfill people’s greater expectations for door lock control.In modern life, access control is no longer just about the simple act of locking and unlocking doors. It now involves considerations of security, convenience, and remote control, among other factors. A control system that integrates multiple unlocking methods such as fingerprint recognition, password entry, Bluetooth connectivity, and RFID card swiping can offer a higher level of access management and user experience, presenting promising applications.
The aim of this research is to design a multi-mode unlocking control system based on a single-chip microcontroller that combines fingerprint, password, Bluetooth, and RFID card unlocking methods. Using the STM32F103C8T6 single-chip microcontroller as the core controller, the system exhibits the following functionalities:Multiple Unlocking Methods: The system supports various convenient unlocking methods, including fingerprint recognition, password input, Bluetooth connection, and RFID card swiping, catering to different user preferences and needs.Card and Fingerprint Management: Users can register or delete RFID cards and fingerprints at any time, with the system supporting up to 50 registered fingerprints and 10 registered RFID cards. This facilitates straightforward permission management.Door Lock Status Monitoring and Abnormal Alerts: The system can monitor the status of the door lock and automatically lock it if there are five consecutive failed attempts to open it, preventing any further operations for 3 minutes. This enhances the security of the door lock.OLED Display Screen: Equipped with an OLED display screen, the system can show passwords and an intuitive user interface, offering a user-friendly experience.Doorbell and Voice Prompts: The system features a doorbell function and supports voice prompts. Users can adjust the volume of voice prompts according to their preferences, providing a convenient means of communication.
Various Password Settings: The system supports multiple password types, including administrator passwords, long-term valid passwords, temporary passwords, and periodic passwords. Users can freely change and save passwords, ensuring easy management.Factory Reset Function: The system offers a factory reset function to allow the resetting of system settings when needed.
This multi-functional unlocking control system combines various convenient unlocking methods, providing users with a high level of security and user-friendliness. It is suitable for various settings, including homes, businesses, and public places, offering reliable access control and management capabilities.
