Design a Smart Meeting Room Occupancy Tracker with Object-Oriented Design

Smart Meeting Room Occupancy Tracker Using Object-Oriented Design

Overview:
The Smart Meeting Room Occupancy Tracker (SMROT) is designed to monitor and manage the occupancy of meeting rooms within an organization. It can provide real-time data about room availability, usage patterns, and assist with booking and scheduling rooms efficiently. Using Object-Oriented Design (OOD) principles, the system will consist of various classes representing different aspects of the tracker, such as rooms, users, sensors, and notifications.

1. Class Definitions:

1.1 Room Class:

The Room class represents each meeting room in the building. It holds attributes like room name, capacity, current occupancy, and status (available or occupied).

python
CopyEdit
class Room:
    def __init__(self, room_id, room_name, capacity):
        self.room_id = room_id
        self.room_name = room_name
        self.capacity = capacity
        self.is_occupied = False
        self.booked_by = None
        self.occupants_count = 0
        
    def update_occupancy(self, occupancy_status, occupant_count):
        self.is_occupied = occupancy_status
        self.occupants_count = occupant_count
        
    def book_room(self, user):
        if not self.is_occupied:
            self.booked_by = user
            self.is_occupied = True
            return True
        return False

    def release_room(self):
        self.booked_by = None
        self.is_occupied = False

1.2 Sensor Class:

The Sensor class is responsible for detecting whether a room is occupied. It interacts with the room object to update the occupancy status.

python
CopyEdit
class Sensor:
    def __init__(self, sensor_id, room):
        self.sensor_id = sensor_id
        self.room = room

    def detect_occupancy(self, occupant_count):
        # Simulate sensor detecting occupancy (simplified logic)
        if occupant_count > 0:
            self.room.update_occupancy(True, occupant_count)
        else:
            self.room.update_occupancy(False, 0)

1.3 User Class:

The User class represents the individuals who are booking or occupying rooms. The system allows users to book a room or check the status of a room.

python
CopyEdit
class User:
    def __init__(self, user_id, name):
        self.user_id = user_id
        self.name = name
        
    def book_room(self, room):
        if room.book_room(self):
            return f"Room {room.room_name} booked successfully by {self.name}."
        else:
            return f"Room {room.room_name} is currently occupied."
    
    def release_room(self, room):
        room.release_room()
        return f"Room {room.room_name} released by {self.name}."

1.4 Notification Class:

The Notification class is responsible for notifying users when a room’s status changes (either becoming available or occupied).

python
CopyEdit
class Notification:
    @staticmethod
    def notify_user(user, room, status):
        if status == "available":
            print(f"Hello {user.name}, the room {room.room_name} is now available.")
        elif status == "occupied":
            print(f"Hello {user.name}, the room {room.room_name} is now occupied.")

2. System Workflow:

1. Room Creation:
   When a new room is set up, an instance of the Room class is created with a unique ID, name, and capacity.

2. Sensor Setup:
   A Sensor instance is attached to each room. The sensor will detect changes in room occupancy, such as when the number of people in the room exceeds zero.

3. User Interaction:

   • A user can request to book a room by calling the book_room method.

   • The system will check if the room is available, and if so, the room is marked as occupied.

   • The system will notify the user about the room’s availability using the Notification class.

   • Users can also release the room once they are done.

4. Real-time Tracking:
   The sensor detects changes in occupancy. If the room becomes empty, it sends a signal to the Room object to update its occupancy status.

3. Example Usage:

python
CopyEdit
# Create rooms
room1 = Room(101, "Conference Room", 10)
room2 = Room(102, "Meeting Room", 5)

# Create sensors
sensor1 = Sensor(1, room1)
sensor2 = Sensor(2, room2)

# Create users
user1 = User(1, "Alice")
user2 = User(2, "Bob")

# User 1 books room1
print(user1.book_room(room1))  # Should print successful booking

# Sensor detects occupancy in room1
sensor1.detect_occupancy(5)  # 5 occupants
print(f"Room {room1.room_name} is {'occupied' if room1.is_occupied else 'available'}")

# User 2 tries to book room1 (already booked)
print(user2.book_room(room1))  # Should print room occupied

# User 1 releases room1
print(user1.release_room(room1))  # Room is released

# Sensor detects room1 is empty
sensor1.detect_occupancy(0)  # 0 occupants
print(f"Room {room1.room_name} is {'occupied' if room1.is_occupied else 'available'}")

# Notification
Notification.notify_user(user1, room1, "available")  # Should notify user1 that the room is now available

4. Key Features:

• Real-time occupancy updates: The system updates room status dynamically based on sensor data.

• User notifications: Alerts users when a room’s availability changes.

• Room booking: Users can book a room, and it tracks the current occupancy.

• Room release: Allows users to free up the room when done.

5. Scalability Considerations:

• This design can be scaled easily to multiple floors or buildings by adding more room and sensor instances.

• Additional features such as room analytics (e.g., peak usage times) or integration with calendar systems (Google Calendar, Outlook) can be incorporated.

This system allows for efficient management of meeting spaces within an organization and provides real-time insights into room usage, enhancing productivity and resource management.
