Thesis - Overview Concepts

  • Agricultural irrigation systems
    • Soil kinds
    • Root distribution
    • Plant (biotic) lifecycle
  • Pressurized irrigation systems
  • Irrigation flow processes
    • Pressurized systems: Filtering
    • Pressurized systems: Pressure  monitoring
    • Irrigation flow timing (on/off durations)
  • Irrigation Systems Power Supplies

Thesis - Naive Theory: Arduino + BBB
  • Arduino for agricultural irrigation - flow control & monitoring
    • Irrigation
      • Motor control
        • PWM
      • Motor type
      • Irrigation flow
    • Flow Rate Sensors
      • Alarm for underflow /underflow rate at any discrete time
        • Overflow: May indicate irrigation line or valve rupture
        • Underflow: May indicate irrigation line or valve obstruction
        • Monitoring system would have to be preprogrammed for 'acceptable' flow rates over time
        • Reporting system may utilize SDN, mobile push
      • Time-duration analysis
      • Agriculture
    • Remote reporting
      • What signal proto?

  • BeagleBone Black (BBB)
    • TI AM35XX Sitara MCU
      • ARM Cortex architecture
      • PRU-ICSS x2 
        • I2C
        • Microprogramming
    • Board Interfaces
