Bike Parking System for S-Trains

Overview

The Bike Parking System for S-Trains is a networked embedded system designed to enhance urban mobility by providing real-time information about bike parking availability on S-Trains. This project aims to streamline the commuter experience in Copenhagen by integrating advanced sensor technology with cloud computing services.

System Architecture

This project employs a multi-tier architecture involving sensing units, data aggregators, a master controller, and a cloud-based server. The system's workflow encompasses data collection, aggregation, processing, and user interface display.

• Sensing Units: Utilizes HC-SR05 Ultrasonic Sensors for detecting bike presence.
• Data Aggregators: Arduino Uno microcontrollers serve as intermediaries to collect and process sensor data.
• Master Controller: An Arduino Uno R4 WIFI microcontroller acts as the central processing unit.
• Cloud Server: Hosted on AWS Elastic Beanstalk, it manages data storage and user interface display.

Repository Structure

This repository is organized into several directories, each containing specific components of the system:

• /Arduino: Contains the Arduino sketches for the different modules.
  • Data Aggregator: Code for the Arduino Unos attached to the HC-SR05 Ultrasonic Sensors. This sketch handles the distance measurement and transmits the status to the master controller.
  • Master Controller: Arduino Uno R4 WIFI code. It aggregates sensor data and sends it to the cloud server.
• /Server: Includes all the code for the cloud server hosted on AWS Elastic Beanstalk
  • server.js: Node.js server script managing incoming data and updating the UI in real-time.
  • index.html: Main HTML file for the user interface.
  • /css: Styling files for the UI.
  • /js: JavaScript files for frontend logic.

Hardware Setup

The project utilizes the following hardware components:

• 2 x HC-SR05 Ultrasonic Sensors: Attached to separate Arduino Uno boards.
• 2 x Arduino Uno: Each programmed with Data Aggregator for sensor data collection.
• 1 x Arduino Uno R4 WIFI: Flashed with Master Controller for data aggregation and cloud communication.

Getting Started

To set up the system:

1. Hardware Assembly: Connect the HC-SR05 sensors to the respective Arduino Uno units as per the circuit diagrams provided in /Diagrams.
2. Flashing the Code:
   • Flash Data Aggregator code onto each Arduino Uno.
   • Flash Master Controller code onto the Arduino Uno R4 WIFI.
3. Server and UI Setup:
   • Deploy server.js to AWS Elastic Beanstalk, and host the rest of Server on a suitable web server.

Usage

Once the system is set up and running:

• The sensing units detect bike presence and relay this information to the data aggregators.
• The master controller processes this data and sends it to the cloud server.
• Commuters can access the web interface to view real-time bike parking availability.
