====== Reference Implementations ======

AOFS provides **validated, non-mandatory engineering reference designs** demonstrating how AOFS-compliant systems may be physically implemented.

Reference implementations illustrate safe and practical deployment patterns.  
They do not define additional normative requirements.

===== Scope =====

This section contains documented engineering examples aligned with:

  * [[architecture:start]]
  * [[operations:start]]
  * [[safety:start]]
  * [[data_model:start]]

These examples translate architectural principles into physical infrastructure layouts, hydraulic systems, and energy configurations.

===== Normative Status =====

Reference implementations are **informative**.

AOFS compliance is determined exclusively by adherence to:

  * Control architecture requirements
  * Safety and fail-safe principles
  * Data model compatibility
  * Operational constraints defined elsewhere in this standard

Replication of specific physical designs is not required for compliance.

Local engineering approval, regulatory compliance, and structural validation remain the responsibility of the deploying entity.

===== Categories =====

Reference Implementations are organized as follows:


==== Infrastructure Blueprints ====

Physical structures supporting irrigation and control systems.

  * [[reference_implementations:water_towers:start|Water Towers]]
  * [[reference_implementations:infrastructure:ground_reservoirs:start|Ground-Level Reservoirs]]
  * [[reference_implementations:infrastructure:pump_houses:start|Pump Houses]]
  * [[reference_implementations:infrastructure:control_enclosures:start|Control Enclosures]]
  * [[reference_implementations:infrastructure:solar_mounts:start|Solar Mounting Structures]]
  * [[reference_implementations:infrastructure:pipe_manifolds:start|Pipe Manifolds]]

Each blueprint documents:

  * Functional purpose
  * Structural concept
  * Hydraulic characteristics
  * Safety considerations
  * Manual operation pathways
  * Controller integration points

----

==== Hydraulic Reference Designs ====

Water distribution and flow system layouts.

Examples:

  * Gravity-fed drip systems
  * Pressure-regulated zonal irrigation
  * Multi-reservoir configurations
  * Overflow and drainage safety layouts

Each design includes:

  * Flow assumptions
  * Pressure constraints
  * Failure modes
  * Safeguards
  * Manual override procedures

----

==== Electrical & Energy Layouts ====

Energy system reference configurations.

Examples:

  * Solar + battery irrigation systems
  * Pump starter protection layouts
  * Surge protection and grounding schemes
  * Brownout-tolerant control wiring

Each layout documents:

  * Power assumptions
  * Protection mechanisms
  * Safety boundaries
  * Manual bypass provisions

----

==== Complete Farm Reference Architectures ====

Integrated examples combining infrastructure, hydraulics, control, energy, and data logging.

These serve as deployment templates and training references.

===== Versioning =====

Each reference implementation:

  * Is versioned independently
  * Specifies compatible AOFS versions
  * Documents assumptions and constraints
  * Records revision history
  * May be revised or deprecated
