Failure analysis based on measurement of vibrometric data
Jánoš, Vít ; Klusáček, Stanislav (referee) ; Šedivá, Soňa (advisor)
This paper deals with the analysis of vibration data from a screw compressor. A single axis piezoelectric sensor is used for the measurements. Within the scope of this work, a software is developed to retrieve the measured data through REST API and perform further processing such as frequency spectrum analysis, envelope analysis or signal cepstrum calculation. An algorithm to compute a fast kurtogram has also been implemented. Kurtogram is used for determination of demodulation band prior to envelope analysis The measured data and the indicators from the analyses are stored in a database.

Measuring station firmware for wireless data collection via LoRaWAN
Jánoš, Vít ; Možný, Radek (referee) ; Juráň, Radovan (advisor)
This thesis deals with software development for STM32WL55-JC1 MCU. Development kit was chosen primarily bacause of its LPWAN possibilities. Final prototype communicates on LoRaWAN network. Data are sent through public network from The Things Network, these data are concentrations of carbon dioxide, temperatures and carbon dioxide flux. Data are also backed up locally on SD card along with timestamp. The software was designed with the use of the chamber measurement method in mind, which is also described in the text.

Measuring Station Firmware for LoRaWAN Wireless Data Collecting
Janos, V. ; Juran, R.
This paper describes the software side of the outdoor carbon dioxide flux low-power measuring station prototype. In the following lines, the selected chamber measuring method is described as well as the IoT protocol LoRaWAN, which is used in this project. The principle of measuring software and following data processing is also introduced. Controlled parts are thermometer, CO2 sensor, and chamber fan. The device is intended to be used in places that have natural sources of carbon dioxide. Measured data are sent through the LoRaWAN network for visualization and further evaluation.
