Измерение температуры с помощью термопары К-типа средствами микроконтроллера

Abstract

Объект исследования – термопары К-типа. Цель работы – разработка устройства для измерения температуры с помощью термопары К-типа средствами микроконтроллера. Задачи: - подбор комплектующих элементов для устройства; - разработка принципиальной схемы устройства; - моделирование схемы в среде Micro-Cap; - разработка печатной платы; - работа в среде программирования микроконтроллеров STM32CubeIDE: конфигурация периферийных устройств, портов, тактирования, генерация и отладка кода инициализации. В результате дипломной работы: было разработано устройство для измерения температуры с помощью термопары К-типа. В основе метода измерения температуры лежит эффект Зеебека. Был использован микропроцессор STM32F103C8T6. С помощью встроенного в него АЦП напряжение с термопары было преобразовано в цифровой сигнал. Актуальность работы. В период сложной политической ситуации импортозамещение больше не пустой звук, а необходимость. На российском рынке приборы для измерения температуры, построенные на доступной элементной базе, стали нужны как воздух. Применение схемы. Разработанное устройство может работать в диапазоне измеряемых температур от 200 до 300° С. Применимо как в промышленности, так и в коммунальном хозяйстве, науке и медицине.

The object of research is K-type thermocouples. The purpose of the work is to develop a device for measuring temperature using a K-type thermocouple using a microcontroller. Tasks: - selection of components for the device; - development of a schematic diagram of the device; - circuit modeling in the Micro-Cap environment; - development of a printed circuit board; - work in the STM32CubeIDE microcontroller programming environment: configuration of peripheral devices, ports, clocking, generation and debugging of initialization code. As a result of the thesis: a device was developed for measuring temperature using a K-type thermocouple. The method of temperature measurement is based on the Seebeck effect. The microprocessor STM32F103C8T6 was used. With the help of the built-in ADC, the thermoEMF was converted into a digital signal. Relevance of the work: During a difficult political situation, import substitution is no longer an empty phrase, but a necessity. In the Russian market, temperature measuring devices built on an affordable element base have become as necessary as air. Schema applicationThe developed device can operate in the range of measured temperatures from 200 to 300° C. It is applicable both in industry and in public utilities, science and medicine.
