Merilnik temperature z možnostjo shranjevanja podatkov na SD kartico

BARUNČIČ, ALEN (author), Vončina, Danijel (mentor)

Diplomska naloga obravnava razvoj merilnika temperature z možnostjo shranjevanja podatkov na SD kartico. Na SD kartico se shranjujejo podatki o temperaturi ter čas opravljene meritve. V diplomski nalogi sem opisal lastnosti posameznih strojnih delov zapisovalnika podatkov, ter postopek razvoja programske kode za delovanje posameznih elementov, ki sestavljajo zapisovalnik podatkov. Uvodni del vsebuje opise elementov (PIC18F8627, RTC, LCD, AD595, SD kartica) ter načrtovanje in izvedbo tiskanih vezij. Glavni del tvorita dve poglavji. V prvem poglavju je opisano zbiranje ter prikaz podatkov, v drugem pa shranjevanje podatkov na SD kartico. V zaključnem delu so opisane še meritve, ki sem jih opravil med praktičnim preizkusom merilnika temperature z možnostjo shranjevanja podatkov na SD kartico. Med praktičnim preizkusom so bili doseženi vsi cilji, ki so bili zastavljeni v uvodu. Vsa programska koda je bila napisana v programskem jeziku C, v razvojnem okolju MPLAB IDE.

• Title: Temperature measurement unit with ability to store data on SD card

Abstract

The diploma thesis presents the development of temperature gauge with the option of storing data on the SD card. These data are the temperature and the time in which the temperature was measured. In diploma thesis characteristics of individual machine parts of data logger and the development process of software code for operation of the individual elements that make the data logger as a whole are described. The introduction contains descriptions of the elements (PIC18F8627, RTC, LCD, AD595, SD card) and the planning and execution of circuit boards. The main part is formed by two sections. The first section describes the collection and presentation of data and the second one describes data storage on the SD card. The final section describes the measurements made during the practical test of temperature gauge with the option of storing data on the SD card. During the practical test is also found relevance of the completed conditions set out in the introduction. All software code was written in C programming language in the development environment MPLAB IDE
