Practice Part
In school we build up a photovoltaic system. Mr Wurmitzer made the power measurement and he will save the data on a PLC. Then Mr. Zivkovic will make the data transmission from the PLC to the database. My part was to create a homepage and many diagrams. If there are new data in the database, the diagram will refresh itself.
Main Part
The Kelag will create us a webservice with a database. In the database the current power will change every minute. The panel temperature, the air temperature and the solar radiation will change once a day.
We connect us to the webserver and grab the data of the webserver and insert it into our database. Then we create a homepage and many diagrams. If there are new data in the database, the diagram will refresh itself.
