HQ / Federated Controller Layer

See overview: System Architecture Overview

The HQ / Federated Controller Layer provides multi-farm oversight, analytics, and management. It sits above Farm Controllers in the AOFS hierarchy, enabling federation, global reporting, and configuration distribution while never bypassing Field Controller safety rules.

The HQ Controller:

• Aggregates telemetry and logs from multiple Farm Controllers.
• Provides management dashboards, reporting, and analytics.
• Supports configuration distribution to Farm Controllers.
• Ensures Field Controller safety authority is always respected.
• Maintains an audit trail of all multi-farm operations and synchronization events.

—

1. Telemetry Aggregation

• Collect irrigation events, sensor data, flow measurements, and operator logs from all Farm Controllers.
• Normalize and store data for reporting and analytics.

2. Analytics & Reporting

• Multi-farm dashboards for water usage, energy consumption, irrigation efficiency, and crop outcomes.
• Alerts for anomalies across farms (e.g., persistent irrigation failures, abnormal flows, power shortages).

3. Configuration Distribution

• Push authorized configuration changes or irrigation schedules to Farm Controllers.
• Ensure updates do not violate local Field Controller safety rules.

4. Audit Logging

• Record all pushes, pulls, operator actions, and synchronization events.
• Preserve audit logs for regulatory compliance and traceability.

The HQ Controller operates as part of AOFS’ decentralized federation network:

• Pull from Farm Controllers:
  1. Retrieve logs, sensor data, irrigation events, and audit trails.
  2. Updates occur automatically or on-demand, queued if connectivity is unavailable.

• Push to Farm Controllers:
  1. Deliver configuration updates, irrigation schedules, or software/firmware updates.
  2. Changes are applied only after Field Controller validation.

• Multi-HQ federation (optional):
  1. HQ Controllers can sync with each other to share aggregated data, analytics, or best-practice configurations.
  2. Conflicts resolved via deterministic rules and logged.

—

• Safety authority:
  • Field Controllers retain full authority for all safety-critical operations.
  • HQ Controller cannot directly actuate pumps, valves, or override irrigation cutoffs.

• Supervisory authority:
  • HQ Controller may propose schedules, thresholds, and configurations.
  • Farm Controllers apply changes according to local rules and validation.

• Conflict resolution:
  • Timestamp precedence and operator approval at the farm level.
  • Any conflicts that violate Field Controller rules are blocked and logged.

—

• Web-based dashboards for multi-farm monitoring.
• Reporting modules for energy, water efficiency, and crop outcomes.
• Interfaces for authorized managers to submit configuration updates.
• Visualization of alerts, events, and historical performance.
• No interface may bypass Field Controller safety rules.

—

• HQ Controller may be offline; farm autonomy is never compromised.
• Logs and updates queue until connectivity is restored.
• HQ can continue analytics and dashboards locally with last synced data, but cannot control irrigation in real-time without live connection.

—

• Hardware: industrial servers, cloud instances, or on-prem appliances.
• Communication protocols: secure LAN, WiFi, cellular, or VPN tunnels.
• Data storage: structured, versioned, and secure for multi-farm ingestion.
• Security: encryption for all communications; multi-factor authentication for operators.
• Scalability: supports hundreds of farms, multiple Farm Controllers per farm.

—

• HQ Controller must never override Field Controller safety rules.
• All multi-farm pushes, pulls, and operator actions must be logged.
• Deterministic conflict resolution must be implemented for configuration and schedule synchronization.
• Failure to respect authority hierarchy invalidates AOFS compliance.
