HIP

January 30, 2006

Colin, Alex, Tom, Jeff, Bryan, Maduna, Alan, Charlie

• Laid-out the architecture of the quark-pmp-wind components and the interfaces.
• Look at the TS-5600 library interface for reading ports rather than /dev/...
• Put together a circuit based on a voltage regulator supplied by the board power port.

Organization Meeting - January 11, 2006

Alex, Bryan, Colin, Tom, Maduna, Jeff, Charlie

• Regular meetings this semester will be on Monday at 12p in the Dennis 4th lab.
• Wind speed and direction - data aquisition/data transfer/packaging/deployment (Colin, Jeff, Alex, Bryan)
• GPS - data aquisition/data transfer/packaging/deployment/ntpd/clients (Alex, Jeff)
• Rain gauge - data aquistion/data transfer/visualization (Tom, Maduna)
• Solar radiation - data aquistion/data transfer (Colin, Maduna)

To Do

Last updated 2006-02-05

• Fix wind chill calculation, use new formula
• Figure-out watchdog timer on PMP
• Backup on PMP - just needs to be put in cron (Tom)
• Wind data for this area (Mary)
• Problems with direction - determine input voltage and calibrate to that (Alex and Colin)
  • Stable voltage needed, e.g. when WiFi card is removed voltage fluctuates. Measure at start and end, if equal than ok.
• Porting wind speed and direction software and setup to pmp, made some progress (Mary, Alex, Colin)
  • Speed working now, using sigalarm(), need a resistor? DIO for power.
  • Direction isn't working yet.
  • Next week on roof?
  • Two weeks in field?
• Sleep and wake on pmp1 with watchdog timer (Mary)
• Weather Cam is working again, cluster camera to be setup in D209.
• RP&L Weather data, contact Gus Duke. Indiana American Water has a link which she sent. (Mary, Charlie)
• Rain guage, Mary has worked on it but it's not working. (Mary, Charlie)
• Solar radiation sensor, continues to make progress, conversion and data comparison (Colin)
  • How to set angle/calibration.
• GPS setup with time server (Tom)

Hardware:

• PMP
  • Technologic Systems TS56000 single board computer running Linux off a SANDisk.
  • URL for the board and documentation
  • To Do
    • Port threaded anemometer code, change code to use local analog/digital inputs
    • Setup NFS mounting of / on the pmp from proto
    • Test analog and digital inputs
    • Setup and test WiFi interface
    • Test and document backup and recovery procedure
    • Identify and recover missing files from SANDisk
    • Design and implement data collection, sleep, and data transfer functions

• Anemometer
  • The Wind direction sends an analogue number.
  • The wind speed is the number of pulses per 2.25 second interval. The number of pulses is the windspeed in MPH.

• We are using a Digi PortServer TS 2, SN=V40611264
  • URL of the documentation

• Rain guage:
  • Sends a pulse every time the cup switches.
