Integrating Embedded Multiagent Systems with Urban Simulation Tools and IoT Applications

The smart city systems development connected to the Internet of Things (IoT) has been the goal of several works in the multi-agent system field. Nevertheless, just a few projects demonstrate how to deploy and make the connection among the employed systems. This paper proposes an approach towards the integration of a MAS through the JaCaMo framework plus an Urban Simulation Tool (SUMO), IoT applications (Node-RED, InfluxDB, and Grafana), and an IoT platform (Konker). The integration presented in this paper applies in a Smart Parking scenario with real features, where is shown the integration and the connection through all layers, from agent level to artifacts, including real environment and simulation, as well as IoT applications. In future works, we intend to establish a methodology that shows how to properly integrate these different applications regardless of the scenario and the used tools.

Development and Implementation of an IoT Platform to Enable Smart Maintenance

IoT solutions represent one of the most powerful approaches towards asset and maintenance management supporting a multi-user environment that can be adopted to monitor machine and guide decision-making at different levels. Several studies discussed the benefits that may be achieved, but few studies discussed how to implement such a complex process that should consider a systematic approach in the development of the infrastructure, platform content, analytics, and internal processes reengineering. To this purpose, the presented chapter describes an IoT platform implementation in a manufacturing company. Specifically, the case study illustrates the steps that have been followed to develop and implement the IoT solution, namely (1) definition of the platform desired functionalities; (2) reengineering of the business processes affected by the platform; (3) development of the proof of concept of the platform dashboards, also considering the data to be sent to the platform; and (4) the implementation of the IoT platform with the connection of customer machines.

SISTEM MONITORING KENAIKAN SUHU PADA TRANSFORMER BERBASIS IoT

Transformers play an important role in generating electrical energy so that in maintaining their performance this transformer has a lot of protection so that the transformer can work as much as possible. Many things can interfere with transformers, namely when the transformer is overheated, a short circuit occurs, or is struck by lightning causing the transformer to burn, so a system that can provide fast, and extensive information is needed and is handled automatically by monitoring the temperature of the main transformer using a smartphone connected to the internet network. In this study, 2 DS18B20 sensors were used which were equipped with a Manual Call Point (MCP) as input and an ESP32 microcontroller module in which there was a Wi-Fi module as a data processor, then the output data would be sent via the internet to the Internet Of Things (IoT) platform for display. In the form of values, graphs, and notifications. The measurement results are in the form of temperature units in C which will be displayed via a smartphone using the Blynk IoT platform in the form of numbers and graphs in real-time according to the value detected by the sensor. Tests on sensors resulted in an average error of 3.29% on the Low side and 3.01% on the Upside.

Partial Discharge and Internet of Things: A Switchgear Cell Maintenance Application Using Microclimate Sensors

This paper proposes a solution for the development of microclimate monitoring for Low Voltage/High Voltage switchgear using the PRTG Internet of Things (IoT) platform. This IoT-based real time monitoring system can enable predictive maintenance to reduce the risk of electrical station malfunctions due to unfavorable environmental conditions. The combination of humidity and dust can lead to unplanned electrical discharges along the isolators inside a low or medium voltage electric table. If no predictive measures are taken, the situation may deteriorate and lead to significant damage inside and outside the switchgear cell. Thus, the mentioned situation can lead to unprogrammed maintenance interventions that can conduct to the change of the entire affected switchgear cell. Using a low-cost and efficient system, the climate conditions inside and outside the switchgear are monitored and transmitted remotely to a monitoring center. From the results obtained using a 365-day time interval, we can conclude that the proposed system is integrated successfully in the switchgear maintaining process, having as result the reduction of maintenance costs.

Development of Car Tyre Air Pressure System (CTAPMS) Using Node MCU ESP8266 Board

CTAPMS is an electronic system designed in this work to monitor the air pressure inside pneumatic tyres on various types of vehicles. A crucial issue in monitoring air pressures of a tyre was most users are too lazy and do not check their car tyre condition daily or before starting a journey. As an assist device for the user to monitor their car air tyre pressure daily, this project has developed the CTAPMS using a BMP180 sensor and Node MCU 8266 microcontroller board. Based on the system, the measured car air tyre pressure can be visualized from the ThingSpeak IoT platform through a smartphone. The performance of the developed system has been validated through a series of experimental works. The result indicates a reliable measurement with an error of less than 10% as compare to the existing system. Further, this product will be commercialized for future use.
