Abstract
Postoji više tipova temperaturnih pretvornika koji koriste različite metode pri mjerenju iznosa temperature. Otporničkim elementima se mijenja otpor u ovisnosti o temperaturi. Termistori, također, mjere temperaturu na temelju promjene otpora, ali od otporničkih elemenata imaju veći temperaturni koeficijent koji može biti pozitivan (PTC) i negativan (NTC). PTC termistorima otpor raste porastom temperature i ne koriste se za mjerenje temperature nego kao elementi za zaštitu. Termoparovi su aktivni pretvornici koji izravno pretvaraju termičku energiju u električnu. Poluvodički temperaturni pretvornici za mjerenje temperature koriste temperaturnu karakteristiku PN-spoja. Senzorski čvor realiziran je pomoću razvojnog sustava STM32F4 Discovery Bord i šest temperaturnih mjernih pretvornika. Za komunikaciju s mikrokontrolerom mjerni pretvornici koriste sljedeće komunikacijske protokole: 1-wire, I2C i SPI. Kako bi komunikacija bila moguća, potrebno je inicijalizirati komunikacijske protokole ili analogno digitalni pretvornik, uskladiti cikluse čitanja i pisanja te ispisivanja podatka. Za programiranje je korišteno razvojno okruženje Keil uVision. U sklopu ovoga rada izrađene su tiskane pločice korištenjem programskog alata Altium Designer.
Abstract (english)
There are several types of temperature transducers that measure the temperature in different ways. Resistor elements changes resistance depending on the temperature. The thermistors also measure the temperature based on the resistance change but they have a higher temperature coefficient then resistor elements. Temperature coefficient can be positive (PTC) and negative (NTC). PTC thermistor resistance increases with rising temperature and it is used like protection elements, not for temperature measurement. Thermocouples are active transducers that convert thermal energy directly into electrical. The semiconductor temperature transducers use the temperature characteristic of the PN-connector. The sensor node was realized using the STM32F4 Discovery Board and six temperature transducers. The transducers use 1-wire, I2C and SPI protocols for communication with microcontroller. To enable communication, it is necessary to initialize communication protocols or analogue digital converter, also coordinate reading and writing cycles and read the data. For programming was used the development environment Keil uVision. As a part of this thesis, a PCB design is developed using Altium Designer. Key words: temperature sensors, temperature transducer, STM32F4 Discovery Board, communication protocol, 1-wire, I2C, SPI
