EMBEDDED SYSTEM FOR TEMPERATURE CONTROL OF MEASUREMENT SURFACE

V diplomskem delu je opisan sistem s katerim se lahko merjenec na merilni ploskvi omejenih dimenzij izpostavlja različnim temperaturnim pogojem. S tem se lahko preverja temperaturna obstojnost in odvisnost merjencev pri različnih temperaturah v omejenem temperaturnem območju. Za merjenje temperature so bili uporabljeni digitalni temperaturni senzorji. Izdelan je bil hladilno/grelni sistem za segrevanje in ohlajanje merilne ploskve. Upravljanje sistema temelji na Atmel-ovem mikrokrmilniku in osebnem računalniku. Za krmilni sistem se je napisala programska koda. Za vodenje, prikaz in shranjevanje meritev pa je bil izdelan uporabniški vmesnik za osebni računalnik.The diploma work describes the system with which we can expose objects to different temperate conditions. With this system we can check for temperate stability and temperature dependence of objects at different temperatures in a limited temperature range. For measuring temperature we have selected digital temperature sensors. We have developed a cooling/heating system for heating and cooling of measurement surface. Management of this system is based on Atmel microcontroller and personal computer. A software code has been written for this control system. For management, presentation, and storage of measurements, a user interface has been designed for a personal computer
