Design and Implementation of Digital Twin Diesel Generator Systems

In stationary power generation units such as distributed remote site power systems and ship power systems, diesel engine generator systems are essential for supplying electricity. This paper proposes a digital twin diesel generator system for teaching and research purposes. A five-layer resilient architecture, including a web interface layer, server cluster layer, real-time data layer, controller layer, and equipment layer, is proposed in this paper. Based on the resilient architecture, users are able to build, implement and monitor the digital twin through web interfaces. Apart from MATLAB/Simulink, a modeling tool called M2PLink is developed to allow users to create mathematical models using a block diagram editor similar to Simulink. Various basic blocks for control systems are provided for users to form sophisticated models. These models are converted into executable codes which are downloaded to the simulator in the controller layer, where the real-time simulations are implemented. A web-based real-time monitoring interface with many widgets such as charts, oscilloscopes, and three-dimensional (3D) animation is also provided for users to customize their monitoring interface. All the signals can be traced and all the parameters can be tuned in the monitoring interface. The users are able to interact with the digital twin just like they do with the real system. The proposed system can not only be used for research such as digital twin-assisted real-time online monitoring but also for educational purposes, which is not only cost-effective but can also ensure the safety of the user as well as the equipment.

Energy Consumption Monitoring System Based on IoT for Residential Rooftops

This work aims to create a web-based real-time monitoring system for electrical energy consumption inside a specific residence. This electrical energy is generated from a micro-CPV system lying on the roof of this residence. The micro-CPV is composed of a Fresnel lens as the main optical element, a spherical lens as the secondary optical element, and a multi-junction solar cell. A tiny photovoltaic concentrator system with a geometric concentration ratio of 100× is analyzed in the first part of this study, while the second part is designed to monitor the electricity generated by the micro-CPV system. An ESP8266 controller chipset is used to build the sensing peripheral node, which controls a relay and a PZEM-004T current sensor. As a result, the optical element used has approximately 83% optical efficiency, with an acceptance angle of 1.5°. Regarding the monitoring system, the architecture demonstrates the ability of the system to monitor current and energy consumption in real time using a computer or smartphone and a web server specially designed to continuously update the power consumption profile in a specific smart home environment. The whole electric power consumption monitoring system generally worked well. The monitoring system is configured to provide excellent accuracy for a 0.6% hit.

Development of cost-effective IoT module-based pipe classification system for flexible manufacturing system of painting process of high-pressure pipe

This paper researches an IoT module-based pipe classification system for a flexible manufacturing system that recognizes the size and length of pipes used in the painting process of high-pressure pipes. The proposed system is composed of an IoT module, USB camera, and edge TPU for pipe classification. The proposed system recognizes the type of pipe by three processes; object detection of the pipe, line detection algorithm of the three regions of interest, and pipe classification algorithm based on the line detection algorithm. Furthermore, the proposed system enables web-based real-time monitoring, providing convenience to workers and helping them make quick decisions. The IoT module interfaces with the painting robot and the sequence control that paints for each type of pipe is executed in the painting robot, allowing flexible manufacturing of the painting process.

For the lack of real-time performance of browser technology in existing Web-based real-time monitoring system, takes use of SVG (Scalable Vector Graphics) and the Comet to design a new Web-based real-time monitoring system. In this system, JSON (JavaScript Object Notation) is the data transmission carrier, Comet is the key technology for system communication and data transmission, and SVG is a chart drawing tool in the browser side. So this system has a good real-time and is rich in the form of show. DOI: http://dx.doi.org/10.11591/telkomnika.v10i5.1347

The Antelope Interface to PHP and Applications: Web-based Real-time Monitoring

The World Wide Web has become a de facto standard for the distribution of wide varieties of data, including monitoring information from real-time systems. The Antelope Environmental Monitoring System (AEMS) is one such system widely used in seismology (Boulder Real Time Technologies 2007). The open architecture of the Antelope system has made it possible to write numerous open-source extensions. The current work describes one such open-source extension specifically designed for the Web. Figure 1. Schematic of the underlying software layers. Data are retrieved from Datascope databases and Antelope orbservers by the Antelope libds.so and liborb.so shared-object libraries, respectively. These native Antelope libraries are linked to the PHP interpreter by the new Datascope.so and Orb.so PHP extension libraries, allowing data to be displayed on Web pages using PHP code embedded in HTML. A parallel sysinfo.so extension library provides access to a number of Antelope system-information utilities. The PHP Hypertext Processor language (referred to by the recursive acronym PHP) is a popular server-side processing language embedded within hypertext markup language (HTML) (PHP 2007; Lerdorf and Tatroe 2002). As an open-source middle layer between Web server and Web client, PHP provides a platform for integrating third-party extensions as dynamically loaded shared objects. The underlying Zend engine (Zend 2007) provides an architecture for easily implementing such extensions (Golemon 2006). Extensions have been developed for a wide variety of purposes, including database connectivity ( e.g. , MySQL and PostgreSQL) and access to services ( e.g. , Mail, FTP, LDAP, and SNMP). These extensions include the many PHP utilities under the PECL online repository (PECL 2007) and reusable applications and components under the PEAR repository (PEAR 2007). We have combined these two technologies (AEMS and Zend) to produce an Antelope interface in the PHP language (figure 1). Initial versions of the interface were written in PHP 4; we …

Application of mobile agents in a web-based real-time monitoring system

Much research has been reported in the area of monitoring real machines using a virtual machining system over the Internet/Intranet. In order to overcome the limitations of net-bandwidth in real-time monitoring tasks, mobile agent technology can be used. This paper proposes a web-based distributed architecture for developing a platform-independent real-time monitoring system. Using this system, users can specify the machining conditions and send the requirements to the central controller. Programs monitoring machining performance can be dispatched from the central controller as mobile agents to the remote hosts where machining signals are sampled from real machines. Finally, an overview of the security issues associated with mobile agents is discussed.
