Project Structure

This project consists of two main directories:

• backend: Contains the ASP.NET Core project for the server-side API.

• frontend: Contains the React project for the client-side application.

Technology Choices

• Backend: ASP.NET Core was chosen for its robust API capabilities and ease of integration with SQL Server.
• Frontend: React.js was selected for its component-based architecture, allowing for a dynamic user interface.
• Database: SQL Server is used for its reliability and support for complex queries.
• Real-time Communication: SignalR is implemented for real-time updates between the server and client.

Main Features

• Automatic Elevator Call Handling
  Incoming elevator calls are automatically assigned to available elevators.

• Elevator State Management
  Elevators move between floors according to their target queue, updating their current floor, door status, and operational status.

• Real-Time Updates
  Elevator status updates are sent to all connected clients in real time via SignalR.

• RESTful API
  Exposes endpoints for managing elevators, elevator calls, users, and buildings using Dapper for data access.

Project Structure

• BL\BlImplementation - Business logic for elevators and calls.
• BL\Bo - Business objects such as BLElevator, BLElevatorCalls, etc.
• Dal\Do - Data objects and data access interfaces.
• Dal\DalImplementation - Implementation of data access using Dapper for efficient database interactions.
• Server - ASP.NET Core server, including configuration, SignalR, and API controllers.

Key Files

• ElevatorBackgroundService.cs
  Background service that runs the main elevator and call management loop.

• ElevatorHub.cs
  SignalR hub for real-time elevator status updates.

• BLElevatorService.cs, BLElevatorCallService.cs
  Business logic services for managing elevators and calls.

• BuildingService.cs
  Service that manages building data using Dapper for SQL queries.

• appsettings.json
  General configuration, including the background service interval and database connection settings.

Getting Started

1. Clone the repository

2. Configure the database
   Ensure your database connection settings in DbContext, appsettings, DalManager are correct.

3. Run the project

   • Open the solution in Visual Studio 2022.
   • Set the Server project as the startup project.
   • Press F5 to run.

4. Test the API
   Use Postman or the provided Server.http file to test API endpoints.

Technologies

• C# 12, .NET 8
• ASP.NET Core Web API
• SignalR
• Entity Framework Core
• Dapper

Elevator System FrontEnd

This project is a web-based elevator system simulator. It provides a user interface to visualize and interact with elevators in a building, allowing users to request elevators to different floors and observe their movement in real time.

Features

• Visual representation of a building with multiple floors
• Interactive elevator controls (call elevator up/down)
• Real-time status display for each elevator (current floor, moving/idle, target floor)
• Modular React components for easy extension
• Styled with Material-UI for a modern look

Main Components

• Building.js: Visualizes the building and elevator, handles floor requests.
• Elevator.js: Represents the elevator car and its state.
• AddBuilding.js: Allows adding new buildings to the system.
• BuildingView.js: Displays a list or details of buildings.
• Login.js: Handles user authentication (if implemented).

State Management

Uses Redux for managing application state, including elevator status, user actions, and building data.

Services

Located in src/components/servers/, these handle API calls and business logic for buildings, elevators, and users.

Getting Started

1. Install dependencies:

   npm install

2. Start the development server:

   npm start

3. Open http://localhost:3000 in your browser.

Technologies Used

• React
• Material-UI
• Redux
