A controller for power et al at FrenchIsland

Requirements

Controls power, water and gas, primarily to preserve resources.

  • LED time remaining
    • Could be a multi segment display, or simpler - e.g. 10 LED count down representing hours
  • Alarm output
    • Beep / alarm output to remind users about to shut down
    • Short beep, repeated a few times = 1 hour remaining
    • Long beep - shut down in 1 minute
  • Relay controllers (power)
    • Mains from Battery (i.e. inverter)
    • Generator off (there is no start, but ability to halt generator automatically)
    • Other low power items (like lights/led etc)
    • GAS - turn off the Gas to the building
    • Water - turn off water at tank, maybe other locations
  • Input buttons
    • Off - turn everything off immediately (including generator)
    • On - turn everything on immediately for 24 hours (except generator)
      • Also reset the timer back to 24 hours when pressed (see LED above)
    • Generator on - turn generator on for 24 hours
      • Maybe consider shorter time for generator, like generator can't be on for more than 3 hours?
      • 3 way switch on generator: OFF; Automatic; ON
    • Consider generator off too

Future / Advanced ideas

  • GAS detector - feed into disable GAS and power, but enable alarm (Alarm and some LED may need to be separately powered)
  • Serial read the Plasmatronic regulator - monitor and record power
  • Remote access - ability to remote access (3G modem) for reading details etc
  • Alarm - with remote access, could be PIR
  • Flow meters
    • Gas
    • Water (in and out and to various things)
  • Current water levels (floats)
  • Weather - rain, wind (speed/direction), temperature, humidity etc.

Inputs required

  • Serial (total = 2)
    • for Regulator
    • Remote access (3G modem)
  • Digital I/O (total = 6+)
    • Buttons - 3+
    • PIR etc - 2+
    • Float levels (n?)
  • Analogue I/O (total = ?)
    • Flow gauges
  • Digital Outputs (total = )
    • Relays = 5
    • Alarm = 1
    • LED display = 10+

Second controller

Keep wires to a minimum and no intelligence (power saving)

  • LEDs (including system running, etc) (3)
    • Basic set - e.g. On, Half, Off
  • Alarm (beeper) (1)
  • Buttons (3)
    • On, Off, Generator off

OR could use a remote keyboard controller which has:

  • Beeper already
  • 3 LEDs
  • Any number of keys and only requires 3 wires (ground, power, signal)

  • Arduino
