CarPark System

A Python-based simulation of a smart car park system, demonstrating object-oriented programming, abstraction, and basic software design principles.

---

Overview

This project simulates a car park with sensors, displays, and logging. It shows how vehicles enter and exit, how available bays are updated in real-time, and how the system tracks all activity. It demonstrates Python OOP, abstraction, composition, and file I/O in a structured project.

Key Skills & Concepts Demonstrated

• Python Object-Oriented Programming (OOP)
  Classes, inheritance, abstract base classes, and encapsulation.
• Software Design & Architecture
  Composition of objects (CarPark contains Sensor and Display objects).
• File Handling
  Logging vehicle activity and saving/loading configuration using JSON.
• Abstraction
  Abstract Sensor class with concrete EntrySensor and ExitSensor.
• Real-time Data Simulation
  Detecting cars and updating displays programmatically.
• Version Control Practices
  Suggested semantic commit messages: feat, fix, refactor.

Technologies Used

• Python 3.10+
• OOP principles: classes, inheritance, abstract base classes
• File I/O (open, Path)
• JSON configuration handling
• Random module for simulating vehicle plates

Classes & Components

CarPark

• Manages vehicles, sensors, and displays
• Keeps track of parked cars and available bays
• Handles logging of vehicle activity
• Updates registered display components

Sensor (Abstract Base Class)

• Base class for all sensors
• Has methods for detecting vehicles
• Subclasses must implement update_car_park(plate)

EntrySensor

• Detects incoming vehicles
• Adds cars to the car park

ExitSensor

• Detects outgoing vehicles
• Removes cars from the car park

Display

• Shows messages and current car park data
• Updates automatically when CarPark state changes
