Abstract

Stroji in naprave v današnjem času proizvajajo velike količine podatkov, ki se navadno prenašajo in hranijo na oddaljenih strežnikih. To lahko prinaša velike stroške prenosa in hrambe podatkov ter zakasnitve, postavlja pa tudi vprašanja o varnosti in zasebnosti. Obdelava podatkov na robu omrežja omogoča, da podatke senzorjev in naprav analiziramo ter obdelamo v njihovi neposredni bližini, v oblak pa pošljemo samo ključne informacije, ki služijo nadaljnji obdelavi. Diplomsko delo opisuje praktičen primer spremljanja učinkovitosti proizvodnega procesa z izračunom kazalnikov skupne učinkovitosti opreme (OEE) na robu omrežja. V okolju TwinCAT poteka simulacija proizvodne linije, ki temelji na modelu stanj PackML. Naprava TwinCAT je povezana z računalnikom Raspberry Pi, na katerem teče program, napisan v programskem jeziku Python, ki zajema podatke iz proizvodnega procesa in v realnem času izračunava kazalnike OEE. Ti se nato prenašajo v spletno aplikacijo Azure IoT Central, kjer ima operater oddaljen nadzor nad učinkovitostjo procesa.

Secondary title: Production process efficiency monitoring with edge computing
Secondary abstract: Machines and devices nowadays produce large amounts of data that are typically transmitted and stored on remote servers. This can lead to high data transfer and storage costs, delays, as well as security and privacy issues. Data processing at the edge of the network allows the data of sensors and devices to be analyzed and processed in their immediate proximity, and only key information is sent to the cloud for further processing. The thesis describes a practical example of monitoring the effectiveness of the production process by calculating the overall equipment effectiveness (OEE) indicators at the edge of the network. The TwinCAT environment runs a production line simulation based on the PackML state model. The TwinCAT device is connected to a Raspberry Pi computer running a program written in the Python programming language, which captures data from the production process and calculates OEE indicators in real-time. These are then transferred to the Azure IoT Central web application, where the operator has remote supervisory control over the effectiveness of the process.
