The architectural and logical overview for the LEDZ GO project
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
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
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
