Architecture

The architecture of Pidgeon is designed to efficiently collect and manage electrical billing data. The diagram below provides a visual representation of the system's architecture.

In the context of a location, there are various types of meters, such as the Abb B2x meter and the Schneider iEM3xxx meter, which are connected via RS-485. The Gateway, accessible via port 502, serves as an intermediary for data communication.

The Raspberry Pi hosts the Pidgeon application, which is divided into three main packages: Configuration, Services, and Processes.

• Configuration: This package contains the Manager component, responsible for managing the application's configuration.
• Services: This package contains several service components:
  • Hardware: Interacts with the physical hardware of the Raspberry Pi.
  • Network: Manages network communications.
  • Modbus: Handles the Modbus protocol for communication with the meters.
  • Database: Manages the local PostgreSQL database.
  • Cloud: Handles communication with the cloud server.
• Processes: This package contains various processes that Pidgeon runs:
  • Discovery: Discovers meters on the network.
  • Ping: Regularly checks the health of the meters.
  • Measure: Takes electrical measurements from the meters.
  • Health: Checks the health of Pidgeon and stores it in the local database.
  • Push: Sends measurements to the cloud server.
  • Poll: Polls the cloud server for configuration updates.
  • Update: Updates the server of meter and Raspberry PI health.
  • Daily: Sets the daily tariff of the meters.
  • Nightly: Sets the nightly tariff of the meters.

Please refer to the diagram for a visual representation of these components and their interactions.
