Smart Parking Management System: Computer Engineering Guide
1. Introduction
Overview of the project.
Objectives of the system: Develop a smart parking management system to optimize parking space utilization and reduce user effort in finding parking spots.
Scope of the system: Applicable for malls, corporate offices, and public parking areas.
2. Requirements Analysis
Functional Requirements:
· - Real-time parking spot availability updates.
· - Automated entry and exit using ANPR (Automatic Number Plate Recognition).
· - Reservation system for parking spots.
· - Payment gateway integration for cashless transactions.
· - Analytics and reporting for parking lot management.
Non-Functional Requirements:
· - High accuracy in spot availability detection.
· - Secure handling of payment and user data.
· - Scalability to handle large parking facilities.
3. System Design
Architecture:
· - IoT-enabled system with sensors and cameras for data acquisition.
· - Cloud-based backend for data processing and user management.
Data Flow Diagrams (DFDs):
· - Level 0: Overview of user and system interactions.
· - Level 1: Modules like Spot Detection, Reservation, and Payment Processing.
Database Design:
· - Tables: Users, Vehicles, Parking Spots, Reservations, Transactions.
4. Technology Stack
Hardware:
· - Sensors (ultrasonic or infrared) for spot detection.
· - Cameras for ANPR and security monitoring.
· - Raspberry Pi or Arduino for edge processing.
Software:
· - Frontend: Web or mobile app using React.js, Flutter, or Angular.
· - Backend: Python (Flask/Django), Java (Spring Boot), or Node.js.
Database:
· - SQL (PostgreSQL, MySQL) or NoSQL (MongoDB, Firebase).
IoT Integration:
· - MQTT or similar protocols for real-time data transmission.
5. Implementation
Hardware Setup:
· - Install sensors at each parking spot for occupancy detection.
· - Set up cameras at entry and exit points for ANPR.
Frontend Development:
· - Design an intuitive interface for booking spots and viewing availability.
· - Implement real-time updates for users via WebSockets or push notifications.
Backend Development:
· - Develop APIs for spot availability, booking, and payment processing.
· - Implement logic for dynamic pricing and analytics.
Integration:
· - Combine hardware and software components for seamless operation.
· - Connect payment gateway services for cashless transactions.
6. Security
Encrypt data during transmission and storage using TLS and AES.
Secure the payment gateway integration with PCI-DSS compliance.
Implement secure authentication mechanisms for users.
7. Testing
Unit Testing: Validate individual modules like spot detection and ANPR.
Integration Testing: Ensure smooth interaction between sensors, backend, and frontend.
System Testing: Test the system under varying load and real-world conditions.
Performance Testing: Evaluate response times and system accuracy.
8. Deployment
Deploy the system in a live parking facility.
Set up cloud services for real-time data processing and backups.
Monitor system performance and address issues promptly.
9. Maintenance and Updates
