Project-Overview

The architectural and logical overview for the LEDZ GO project

User Interaction

The user will interact in the following way with the system:

• Choose between the different saved scenarios
• In a scenario:
  • Choose the mood (automatic function)
  • Issue a direct command to a light
  • Create new mood
  • Set up scenario
• Create new scenario

General Architecture

The image bellow describes the general architecture for the project. We can distinguish 3 different agents in the project :

• Smartphone : Containing the application the user will interact with
• Master Node : Receiving the commands from the smartphone and dispatching it to the other nodes
• Nodes : Receiving the commands from the Master Node and translates it into a DMX signal to the DMX light

We can also distinguish 3 different connection types:

• Smartphone - Master Node : Via bluetooth
• Master node - Nodes : Via WiFi
• Node - DMX Light : Via DMX signal

Team Work

The project is divided into 4 parrallel workflow :

• Communication Layer
  • WiFi connection between Nodes and Master Node
  • SSID and general parameters configuration for automatic connection
  • "Plug and Play" feature
  • TCP/UDP socket
  • Network maintenance protocols (Keep Alive...)
• Application Layer
  • JSON messages format
  • Master Node dispatch
  • Master Node "DMX Light Automatic Function Mode" handler
  • Network maintenance messages
  • Interrogation du Réseau
• Smartphone App Frontend
  • User interface in the smartphone
  • Opens Bluetooth connection with Smartphone
  • Handles the Bluetooth connection with Smartphone
• DMX Node Communication
  • Parses the input data
  • Translate it into approriate DMX signal
