Opis:
Today, technology has transformed humans’ lives in all areas. Technology can be found in everyday life in the form of smart factories, smart cities and smart rooms. Thus, smart systems and devices are having a great effect upon human activities. Together with improving technology, in the last 50 years, the human population has seen an expeditious and substantial increase. The number of cars has also substantially increased and, as a result, parking spaces and car park have become more important. Areas in which to park cars have become wider in scope, including inside huge buildings; thus, the management of them become more difficult and complicated. Being able to discover an empty parking space as soon as it is needed is vital for both driver and multilevel parking garage owner, especially for the former, in order to avoid losing him/her time and money in a crowded city. Thus, we designed a smart car parking system, which is managed by Arduino control. Our main aim includes reducing time loss and the amount of fuel consumed while trying to find a parking space. By reducing the amount of consumed fuel, it will be possible to reduce air pollution levels, together with minimizing the negative impact on domestic finances caused by car usage.

Opis:
This research was devoted to the creation of a protection system for electric motors used in industry and transport, based on modern and traditional sensors. In the course of operation, the malfunctions of electric motors have been investigated and it was found that the accident modes occur mainly due to exceeding the permissible values of the current, voltage and temperature parameters. Modern sensors of current, voltage, and temperature have been compared and the most effective ones were selected for use in electric motors. Based on reasoning from these sensors, a protection system for a low-power electric motor has been developed in the laboratory. In addition, in the Multisim application software package, a simulation of the operation of the protection system at different voltage and current values was performed, and a circuit of the sensor control unit and the power source for powering the protection system was constructed. It has been proposed to apply such a multi-parametric complex protection system for electric motors, especially in transport.

Opis:
The paper describes an attempt of using magnetic detectors as an effective alternative to existing vehicle detection systems, which are a key factor in intelligent transportation systems (ITS). The detectors created within the project use the phenomenon of anisotropic magnetoresistance to report about the appearance of vehicles on the basis of Earth's local magnetic field distortion caused by them passing. This paper presents utilized and developed technologies, advantages and disadvantages of magnetic detection in comparison to other detection systems and problems that arose during the project implementation.
Artykuł opisuje próbę zastosowania czujników magnetycznych jako skutecznej alternatywy dla istniejących systemów detekcji pojazdów w ruchu ulicznym, będących kluczowym czynnikiem inteligentnych systemów transportowych (ITS – Intelligent Transportation Systems). Czujniki stworzone w ramach projektu wykorzystują zjawisko magnetooporu anizotropowego do raportowania o pojawieniu się pojazdu na podstawie zakłóceń, jakie wywołuje on w lokalnym polu magnetycznym Ziemi. Praca prezentuje wykorzystane i stworzone technologie, wady i zalety detekcji magnetycznej na tle innych systemów detekcyjnych oraz problemy, które wyniknęły przy implementacji projektu.

Opis:
The carriage of food products, in particular fresh products, is particularly sensitive to transport conditions. The aim of this paper is to examine the effect of trailer conditions on the quality of refrigerated food transport services. Six wireless measuring devices installed permanently in 3 trailers were used for the analysis. The built-in transmitter sensors have enabled the collection of data in the areas of temperature, humidity, pressure, shock and light intensity. Monitoring parameters via a wireless device can contribute to the reduction of fuel costs in the enterprise, e.g., detection with vibration sensor / acceleration of aggressive driving style of the driver causing suspended fuel consumption, detection of inappropriate transport conditions, etc. Analysis of the test results showed that in the same trailer the product distribution is very important owing to the different temperature. The analysis carried out showed that in the middle of the semitrailer, i.e. in the place where the breeze is located, temperature fluctuations amount to 5°C, which indicates a greater risk of loss of quality of the transported products.

Opis:
Purpose: The aim of the article is to identify the quality control methods used in companies producing packaging and to obtain knowledge of the scope of the use of optical sensors. Design/methodology/approach: Enterprises located in Poland in the Greater Poland Voivodeship, producing paper, board, corrugated and plastic packaging. The triangulation strategy was used in the study in which Computer Assisted Web Interview (CATI), Individual In-depth Interviews (IDIs), and Case Study were applied. The subject of research was the identification of quality control methods at individual stages of packaging production and the responsibility for carrying it out, as well as the method of presenting the control results. In addition, the use of optical sensors for quality control was assessed. Findings: Digitalization of manufacturing leading to the Industry 4.0 concept provides novel tools for quality control and data storing. It enables real-time data collection and processing for even better even better management of the production process and quality control. However, the concept of Industry 4.0 (including Big Data Analysis, Internet of Things, Artificial Intelligence, Neural Networks) is not new, still many companies find it difficult to implement it and benefit from its capabilities. The surveyed packaging companies are characterized by low use of the possibilities related to the use of more advanced methods of product quality control at individual stages of the production process. The potential for improvement is the area of process and product control through the use of optical sensors/actuators, etc., and the form of keeping records of the product quality checks carried out. Research limitations/implications: The results of this research are not representative, but they encourage the authors to carry out a broader and more in-depth analysis of the research subject on a national scale. Practical implications: Research indicates the need to improve the quality control process in the production of packaging and a wider use of modern solutions with the use of optical sensors. Originality/value: An article can be an element influencing the management to better select quality control methods at various stages of the production process.

Opis:
In this investigation, the problem of moving object detection - without any knowledge - is classified. It describes a technique that will allow real-time localization with usage of IR sensors. The proposed algorithm is simplistic, and in the future, it might be implemented into any vehicle, premium or entry level. It is guided by AI that must calculate its next moves in the blink of an eye without user noticing any delays. The main problem of moving object recognition was extraction of proper features, description of the events, and choice of only the crucial ones. The presented novel approach does not follow any standard algorithms. It is a practical hardware implementation of custom solution, based on processing system, which can be well situated in the safety modules of future cars.

Opis:
Vibration diagnostics is of particular importance in rail transport safety systems because the signals received from vibration sensors installed on rolling stock, bridges, tunnels, and other infrastructure objects have great diagnostic information potential. Despite this, in practice, there are cases when the adequacy of the results of the vibration control and diagnostics task is not ensured. The reason is that the sampling step of the vibration signal does not change when the train speed changes. Given the need to change the sampling interval depending on the train speed, this article proposes an adaptive technology for vibration signal sampling that allows the building of intelligent systems of adaptive vibration control of malfunctions in rail transport.
