Data acquisition system of a flexible solar collector
| Resumo: | The aim of this Master Thesis work is to create a weather station based on sensors by creating a data acquisition system with LabView in purpose to collect data for solar collector based on the European standard for solar collector testing. EN 12975-2(CEN 2006) offers two different methods for characterizing the thermal performance of solar thermal collectors: The steady state (SS) method and the quasi-dynamic method (QDT). The process of building the data acquisition system begin by choosing thermocouples and NI USB-6008 DAQ device to measure ambient temperature, LM35 sensor and NI myDAQ for the inlet mass flow measurement, for the surrounding air speed we used vernier anemometer with NI myDAQ, another thermocouple type k for surrounding air temperature measurement and a pyranometer with NI USB-6008 for global and diffuse irradiance. Hence, The main action of data acquisition systems is the sampling signals that measure real world physical conditions (voltage, current) and converting the resulting samples into digital values that can be handled, for example, by a computer. This project describes the fundamental concepts of data acquisition systems; in particular sensors, transducers, communication cabling, and system configurations. |
