Arduino Power Monitoring Project v1.2


Xml Impulses List Output:


Database:

  • Host: apm.in.nessus.at
  • User: apm
  • Pass: xxx
  • TABLES:
- impulses (contains all impulses data inserted)
- mapping (contains all mapped RACK_ID to PRIMARY_ID of table IMPULSES)
- rack_impulses (view containg merged information)


Django Web Frontend (temporary)



Hardware used/developed:

  • Arduino Duemilanove Atmel328 (Diecimila Atmel168)
  • Multiplexer Shields (8x Maxim-Intersil DG406)
  • Forlong DRS-201D kWh meter


Software used/developed:

scripts path @apm.in.nessus.at:/home/bons/apm

  • Arduino
 - Arduino_PM 1.2b (source code) revision B
 - Arduino_PM 1.3 (source code) version 3
             added sync feature between arduino memory and db
  • Python
 - apmrobot.py - Apm Robot for XML data import - (source code)
 - sync2db.py - Sync2db XML-arduino-memory and DB  - (source code)
 - memreset.py - Cronjob runs every monday and resets impulse memory of the arduino to prevent overrun
  • USAGE:
 - apmrobot.py - Parse XML output from ARDUINO and INSERT data in DB (sanity value check control included)
 - sync2db.py param1 param2 (where param1=RACK_ID and param2=KWfromDISPLAY to sync) 
         example: "sync2db.py N1P1 100" 
               this will update the DB value of RACK N1P1 with value 100*2000 (1kw/h = 2000 impulses)
               and reset the memory of the arduino for that rack to 0 to start counting

Project RoadMap:

  • Circuit:
    • Multiplexer Shield Circuit Design
    • Conversion with script metaboard.sh (process developed @ Metalab.at) to output file for CNC
    • Milling and Drilling with CNC
    • Soldering and Cabling


  • Software:
    • Arduino
      • Reading impulse on GPIO pins
      • Cycling Multiplexers
      • Store multiplexing and impulses data in "unsigned long" 3d matrix (2x16x8) [impulse capacity upgraded to 2^31-1]
      • Webserver with live XML output available on EthernetShield


    • Python
      • Manage data import from arduino memory xml (parse, check, insert)
      • Sync arduino memory with db to current read value (webserver http get parse for parameters)
      • Django DB model for data stored in memory
      • Django Views for showing stored Power Information
