    Encoding and decoding controller area network frames using the CAN database
    (Видавництво Львівської політехніки, 2023-02-28) Ivaniuk, Oleg; Vlakh-Vyhrynovska, Halyna; Modla, Roman; Kulyk, Nazar; Lviv Polytechnic National University
    The article examines the features of building a Controller Area Network (CAN) in the automotive industry. The main steps for encoding and decoding physical values in CAN and CAN FD (CAN with flexible data rate) frames are provided. The syntax of messages and signals in CAN DBC has been analyzed. An example of a DBC file that can be used to encode and decode the speed and engine speed of a truck is reviewed. Based on the Linux operating system and the python programming language, an experimental scheme of a virtual controller area network was created, which encodes data on one node and decodes data on the other using CAN DBC.

    Intelligent system of temperature monitoring in refrigerated containers
    (Видавництво Львівської політехніки, 2023-02-28) Vlakh-Vyhrynovska, Halyna; Dzelendziak, Ulyana; Ivanyuk, Oleh; Vyhrynovskiy, Mishel; Lviv Polytechnic National University
    The work emphasizes the importance of maintaining a consistent temperature while transporting temperaturesensitive goods in the logistics cold chain. Refrigerated transportation plays a critical role in this chain, and the safe and efficient transport of perishable goods, such as food or pharmaceuticals, heavily relies on maintaining appropriate temperature levels. Realtime temperature monitoring and timely response to deviations are vital to prevent spoilage and financial losses. This paper presents an intelligent temperature monitoring system that employs a WiFi-enabled IoT platform NodeMCU-ESP32 to collect realtime temperature data, which is then transmitted to the AWS cloud platform. The system uses machine learning algorithms to predict temperature deviations and sends alerts to relevant stakeholders via the Telegram messaging service. The system architecture comprises AWS services, including API Gateway, IAM, Lambda, DynamoDB, and SNS, offering a scalable, secure, and costeffective temperature monitoring solution.

    Study of real-time operating system including programmable logic controller functionality
    (Видавництво Львівської політехніки, 2023-03-01) Dzelendzyak, Ulyana; Vanyuk, Vladislav; Vlakh-Vyhrynovska, Halyna; Węgrzyn, Mariusz; Lviv Polytechnic National University; Cracow University of Technology
    t. The article describes the developed real-time operating system “VladOS”, which is a set of modules and utilities from which the required system for controlling the eco-house should be assembled. Users can load their written applications into the file system in the form of binary files. System generation involves selecting an active configuration from a list of available user applications, setting values of system configurations, compiling system module parameters using this configuration, and linking system modules into an executable program. Additionally, the performance of the developed operating system is assessed through a comparison with the widely recognized Arduino core, with the “SmartHatka” treehouse serving as a representative example. Essentially, “SmartHatka” is a Ukrainian smart eco-house.
