Development of hardware and software complex for collecting and storing thermometry data
Incoming article date: 30.12.2021Internet of Things (IoT) technologies are widely used in many fields today, including the power engineering. This article describes the development of a hardware and software complex for collecting and storing thermometry data. Related works are considered. The complex includes the data collection and transmission module and the database on the server. Measurement indicators are collected and transmitted using the Arduino Uno platform. For temperature measuring, the thermocouple is used, the normalizing converter converts the signal from the thermocouple. The signal gets to the input of the ATmega328 microcontroller of Arduino Uno platform. Data transmission is carried out wirelessly by EPS-12 microcontroller using the MQTT application layer protocol and Wi-Fi channel protocol. The database was implemented using the MySQL database management system. The developed software and hardware complex is used for steam boiler condition monitoring at the thermal power plant of the Moscow Power Engineering Institute.
