Project Description

The Smart Door Access System is a full-stack intelligent access control management platform built with FastAPI, Vue 3, and STM32. It supports multi-device management, user access control, access log monitoring, AI-powered intelligent access control, and communication with physical hardware devices (password keypad, fingerprint scanner, RFID card reader, etc.) through MQTT.

Features

1. 🔒 Comprehensive Security and Access Management

Fine-Grained Access Control

Clearly separates administrator and user privileges, ensuring that only authorized personnel can access designated areas.

Remote Door Control

Administrators can remotely unlock doors from anywhere through a secure web interface with a single click, with every operation fully authenticated and verified.

Transparent Access Log Management

Provides detailed records of:

• Who accessed the system
• When access occurred
• Which door was used
• Failed access attempts

Logs are organized with pagination for efficient searching, auditing, and tracking.

2. 🤖 AI-Powered Smart Operations with Real-Time Data

AI Assistant for Access Control

Users can interact with the system using natural language commands such as:

"Open the first-floor entrance door."

The AI automatically identifies the target device and executes the access request without requiring complex system navigation.

Real-Time Dashboard

Key operational metrics are updated instantly, including:

• Daily visitor count
• Registered device status
• Door opening statistics
• System activity overview

Instant Event Notifications

Administrators receive real-time notifications whenever:

• Access events occur
• Device status changes
• Security incidents are detected

This enables immediate response to operational situations.

3. 🏫 Optimized for Large Facilities and Campus Environments

Multi-Facility Management

Ideal for environments with numerous access points, including:

• University campuses
• Research laboratories
• Dormitories
• Corporate offices

Each access device can be assigned a unique identifier and location information for centralized management without confusion.

Flexible User-Device Assignment

Administrators can easily assign or revoke access permissions by linking users to specific devices, making personnel transfers and onboarding processes more efficient.

4. ⚡ High Performance and Reliability

High-Speed Processing

Built with high-performance technologies such as:

• FastAPI
• Redis
• MQTT

The system efficiently handles large datasets and AI conversation logs, ensuring smooth operation even under heavy concurrent usage.

Easy Deployment and Maintenance

The platform automates many initial configuration tasks and is designed with maintainability in mind, reducing both deployment time and long-term operational costs.

• Network-controlled door locks

the Smart Door Access System can integrate multiple authentication methods into a unified platform, including:

• RFID
• NFC
• Password authentication
• Mobile applications
• Facial recognition
• Biometric verification

Furthermore, by leveraging WIZnet Ethernet solutions such as:

• W5500
• W5100S
• WIZ750SR

the system can support:

• Real-time access log transmission
• Remote permission management
• Access analytics and reporting
• Building Management System (BMS) integration

This enables expansion beyond basic door control into:

• Smart office solutions
• Smart building management
• Industrial access control
• Security monitoring systems

Additionally, integration with existing RFID-based access projects can strengthen authentication capabilities, while combining with WIZ750SR-based smart lock projects can create a complete remote-access management solution.

Role and Application of WIZnet Chips

In this project, WIZnet Ethernet technology serves as the core networking infrastructure that connects smart access devices to centralized management systems.

WIZnet chips can be utilized for:

• Access log transmission to servers
• Remote door status monitoring
• Synchronization of authentication data with management servers
• Real-time event and alarm notifications
• Reliable wired Ethernet connectivity

Because access control systems require a high level of security and reliability, Ethernet-based communication is often preferred over wireless alternatives.

WIZnet Ethernet solutions provide robust and dependable TCP/IP networking for these mission-critical environments.

Market and Application Value
