Abstract

U današnjem svijetu se sve više koriste pametni uređaji poput prijenosnih računala, pametnih telefona, pametnih satova i ostalih pametnih naprava koje su međusobno povezane kako bi se mnogi procesi pojednostavili i ubrzali. Te pametne uređaje je moguće primijeniti na digitalizaciju i automatizaciju proizvodnih procesa u tvornicama. Kao primjer jedne takve primjene napravljen je pametni uređaj za mjerenje debljine paketa jezgre transformatora koji je opisan u ovom radu. Uređaj je baziran na Raspberry Pi platformi koja ima vrlo velik broj mogućnosti i primjena, uz relativno nisku cijenu. Opisane su neke od tih mogućih primjena, komunikacijski protokoli koje Raspberry Pi koristi te njegove prednosti i mane. Pametni uređaj koristi lasere za mjerenje debljine paketa jezgre i digitalnu libelu za mjerenje nagiba lima jezgre transformatora, a za napajanje se koristi baterija. Upravljanje pametnog uređaja se izvršava uz pomoć android aplikacije na tabletu. Android aplikacija je napravljena u programskom jeziku Python, u razvojnom okviru Kivy. Tablet se spaja preko Wi-Fi mreže na Raspberry Pi pločicu da bi mogli međusobno izmjenjivati informacije i naredbe. Tablet aplikacija sprema mjerenja debljine paketa jezgre u obliku Microsoft Excel tablice. Opisan je proces mjerenja debljine paketa jezgre transformatora s pametnim uređajem i način rada tablet aplikacije.

Abstract (english)

In today's world, smart devices such as laptops, smartphones, smartwatches and other interconnected smart gadgets are increasingly being used to simplify and speed up many processes. These smart devices can be applied to digitalization and automation of production processes in factories. As an example of one such application, a smart device for measuring the thickness of a transformer core package was developed, which is described in this paper. The device is based on the Raspberry Pi platform which has a very large number of features and applications, with a relatively low price. This paper describes some of these possible applications, communication protocols used by the Raspberry Pi, and its advantages and disadvantages. The smart device uses lasers to measure the thickness of the core package and a digital spirit level to measure the slope of the transformer core sheet, and a battery is used to power it. Control of the smart device is performed with the help of the Android app on the tablet. The Android app was made in the Python programming language, in the Kivy framework. Tablet connects via a Wi-Fi network to the Raspberry Pi board so they can exchange information and commands with each other. The tablet app saves core package thickness measurements in the form of a Microsoft Excel spreadsheet. Process of measuring thickness of a transformer core package with the smart device and operation of the tablet app are described.
