Abstract [sv]

Inledning

ASV Solar har sett en brist på dagens styrsystem för anläggningar vid utvinning av solvärme. De önskar då ett system som klarar av att styra separata panelsektioner, är skalbart och har ett användarvänligt webbgränssnitt.

Metod

Genom design och tillverkande av NodKontrollers som ska placeras på tak och vid tank att inhämta sensordata samt styrning av aktuatorer. Kommunikation mellan noderna sker via CAN bus där insamlad data skickas till en lokal databas för att sedan kunna visas via ett grafiskt gränssnitt en lokal webbserver. Här ska användaren sedan kunna ändra styrparametrar för systemet.

Resultat

En prototyp bestående av två NodKontroller har producerats, dessa samlar in temperaturdata från tank och tak samt sköter styrning av magnetventil och flödespump. Användaren kan via webbservern se loggad data samt sätta värden för styrning av system.

Introduction

The company ASV Solar have identified a shortcoming in the control systems used in the equipment used for extraction of solar thermal extraction. They desire a system that can control separate sections if solar thermal panels, that is scalable and have a user friendly web interface.

Method

Through design and manufacturing of NodeControllers that will be placed on the roof and around the heat storage tank. These nodes will collect thermal data and control the water pump. Communication between the nodes is done over CAN bus where the collected data is sent to a local database to be displayed through a graphical interface on a local web server. In the web interface the user can set control parameters for the system.

Result

A prototype consisting of two NodeControllers have been produced, these collect the temperature data from the roof and heat storage tank, also managing the control of solenoid valve and flow pump. The user can through the web interface access stored data and set control values for the system.
