Energy Display Scripts Outline

  1. Java scripts harvest data directly from Modbus
  2. Perl scripts collects this data and put it in the Postgress database "energy" under the table "electrical_energy"
    • electrical_energy attributes:
      • area - what building.
      • preal - kW hours for that instant.
      • date - date of harvest.
  3. A final perl script (display/production|development/js-file-gen.pl) accesses this data and generates a .png graph using the Google graph API
    • This script takes one parameter for either the production or development branches.
  4. The images generated (day, week, month, year) are put in a html frame on a page to display the data.
    • This page refreshes every 5 minutes
