Real-time monitoring and control of a PV-fed enhanced cubic voltage gain converter for DC microgrid

In this manuscript, a novel high-gain DC-DC converter with an ultra-step-up voltage gain value of 22.2 is introduced along with a custom-developed web application for remotely monitoring and controlling the power converter. The proposed converter is synthesized using two stages – stage 1 yields a cubic voltage gain and stage employs a diode-capacitor gain cell (DCGC) to reduce the voltage stress on the switch. The proposed gain extension hypothesis is experimentally validated through an 18 V to 400 V, 175 W prototype converter which delivers 175 W to the load at a 93.5% efficiency. The proposed converter exhibits excellent dynamic response when regulating the output voltage to 400 V over a wide range of input voltage and load current variations; the overshoots and undershoots are also negligible. Further, the maximum voltage stress on the switch is only 37.5% of the output voltage. For remotely controlling and monitoring the converter under real-time conditions with a high sampling rate, a web application is developed using React.js. The STM32 microcontroller is programmed to transmit data serially to the server, which then interacts with the web application using hypertext transfer protocol (HTTP) and WebSockets. The effectiveness of the developed interface is also practically verified by controlling the proposed converter in various modes viz., open-loop, soft-start, constant voltage, constant current, soft-stop, load regulation and overvoltage protection modes. Based on the comparison with several converters the proposed converter possesses unique advantages. Additionally, its web-based remote monitoring and control features are preferable for DC microgrid application.

Web-based digital twin modeling and remote control of cyber-physical production systems

Abstract The rapid development new generation of information technologies facilitate the emergence of cyber-physical production system (CPPS) which could pave a way to exploring new smart manufacturing solutions. Digital twin (DT) is the technical core for establishing CPPS in the context of industry 4.0. Developing an easy-to-deploy and simple-to-use DT-based CPPS is a critical research gap. In this paper, a systemic framework is proposed to provide guidelines for rapid system configuration and easy runtime of DT-based CPPS by integrating CPS, DT modeling technologies, event-driven distributed cooperation mechanisms, and web technologies. The concept of CPS node (CPSN) for manufacturing resources is established by integrating semantic information model, 3D geometric model and function modules. Various CPSNs are orchestrated as an autonomous CPPS using dynamic resource registration and binding technologies. To achieve easy runtime of DT-based CPPS, event-driven distributed cooperation among CPSNs and web-based remote control of CPPS are proposed respectively. Finally, to verify the feasibility of the proposed framework, a prototype of DT-based CPPS is implemented, based on which an exemplary case is conducted.

Design of EPICS and Web-Based Remote Control Software of Near-Infrared Sky Brightness Monitor in Antarctica

The Near-infrared Sky Brightness Monitor (NIRBM) aims to measure the middle infrared sky background in Antarctica. The NIRBM mainly consists of an InGaAs detector, a chopper, a reflector, a cooler and a black body. The reflector can rotate to scan the sky with a field of view ranging from 0{\deg} to 180{\deg}. Electromechanical control and weak signal readout functions are accomplished by the same circuit, whose core chip is a STM32F407VG microcontroller. Considering the environment is harsh for humans in Antarctica, a multi-level remote control software system is designed and implemented. A set of EPICS IOCs are developed to control each hardware module independently via serial port communication with the STM32 microcontroller. The tornado web framework and PyEpics are introduced as a combination where PyEpics is used to monitor or change the EPICS Process Variables, functioning as a client for the EPICS framework. Tornado is responsible for the specific operation process of inter-device collaboration, and expose a set of interfaces to users to make calls. Considering the high delay and low bandwidth of the network environment, the tornado back-end is designed as a master-and-agent architecture to improve domestic user experience. The master node is deployed in Antarctic while multiple agent nodes can be deployed domestic. The master and agent nodes communicate with each other through the WebSocket protocol to exchange latest information so that bandwidth is saved. The GUI is implemented in the form of single-page application based on the Vue framework which communicates with tornado through WebSocket and AJAX requests. The web page integrates device control, data curve drawing, alarm display, auto observation and other functions together.

Web-Based Remote Control of a Building's Electrical Power, Green Power Generation and Environmental System Using a Distributive Microcontroller.

This article proposes a novel, web-based, remote monitoring and control system design for a building’s electrical power, green power generation and environmental system that will save energy. The supervisory control system is based on the use of distributed microcontroller architecture to access programmable logic controllers (PLC) and remote input/output devices through the system hardware framework with uniform Ethernet technology. The programmable logic controller (PLC) can access and control devices directly or through RS-232 and RS-485 serial communication. The distributed microcontroller is the control module designated through an open-source firmware, to transform heterogeneous communication to Modbus transmission control protocol (TCP) communication and to achieve the exchange of information between the host and client controller. The proposed supervisory control and data acquisition (SCADA) system is based on the professional software of InduSoft Web Studio and provides a supervisory control design with a friendly human–machine interface. The system can realize real-time data acquisition and storage, control command transmission, system security and power trend analysis. Finally, the proposed SCADA system can be built directly into the hypertext markup language (HTML) and HTML5 and run on the web server, allowing access from a personal computer or smartphone web browser. Our system goals are to greatly reduce system complexity and maintenance costs with a simple Ethernet architecture. The control system can be easily expanded with the same technology culture outside the restrictive one of the large companies. Hence, this system can easily be used in a smart home system to enhance the quality of its inhabitants.

Implementation of a Web-based remote control system for qZS DAB application using low-cost ARM platform

Abstract Continuous development of intelligent network applications drives the demand for deployment-ready hardware and software solutions. Such solutions are highly valued not only by distributed producers of energy but by energy consumers as well. The use of intelligent network applications enables the development and improvement of the quality of services. It also increases self-sufficiency and efficiency. This paper describes an example of such device that allows for the control of a dual active bridge (DAB) converter and enables its remote control in real time over an IP-based network. The details of both hardware and software components of proposed implementation are provided. The DAB converter gives a possibility to control and manage the energy between two DC power systems with very different voltage levels. Not only information, but also the quality of energy, the direction of power flow, and energy storage systems can be easily controlled through an IP-based network and power electronics converters. Information technology, together with intelligent control of power electronics technology, provides a flexible solution, especially for sustainable smart grids.

Collaborative robot monitoring and control for enhanced sustainability

This paper presents a new approach for real-time collaborations in adaptive manufacturing, including web-based remote monitoring and control of an industrial robot, and active collision avoidance for human–robot collaborations. It is enabled by using virtual 3D models driven by real sensor data and depth images of human operators. The objectives of this research are to significantly reduce network traffic needed for real-time monitoring over the Internet and to increase human safety in a human–robot coexisting environment. The ultimate goal is to enhance the sustainability of manufacturing operations in decentralised dynamic environments with safety protection. The results of a case study show that the approach consumes less than 1 % of network bandwidth of traditional camera-based methods and is feasible and practical as a web-based solution.

Web-Based Monitoring and Control of Industrial Processes Used for Control Education

Web-based technologies enable the implementation of remote monitoring and control of industrial plants. In this paper, some solutions and advantages of using distributed process control systems for control education are presented. In the area of process control teaching, practical experience plays an important role and web-based technologies enable the implementation of remote experiments onto real laboratory or industrial systems for effective engineering education. We present our experiences with two remote experiments based on distributed control systems realized on laboratory systems. The user interface of the first experiment is implemented by professional supervision tools and is using web-based SCADA technology. In the second experiment we discuss the process of developing fault detection and isolation applications for online and remote education by using industrial equipment from the field of process technology (batch, continuous) supported by web technologies. Through-out the course, the student can remotely develop and test model-based and data-driven FDI schemes in Matlab/Simulink by using OPC technology. Finally, the improved platform for web-based remote control system experiments suitable for control education is proposed.

Web-based remote voice control of robotized cells

The main goal of research presented in this paper was to develop an effective tool for remote voice control of robotized cells. This goal has been achieved by proper combination of two techniques: automatic speech recognition and web-based remote control of robotized cells. Comprehensive analysis of existing solutions related to the control with voice commands and those related to the web-based remote control has been performed. Usually the above mentioned topics are dealt with separately. Only few works tried to cope with the problem of how to combine solutions in these two areas. None of them was aimed at industrial applications. Unlike those works, my research is focused on remote voice control of industrial robotized cells. Besides, my approach does not presume application of a small set of simple pre-defined voice commands but it is based on the use of quasi-natural language instead. The main result of this research was the architecture of industrially oriented remote voice control system. Theoretical considerations have been practically verified in the laboratory. According to my knowledge, this laboratory implementation is the first-ever industrially oriented operational remote voice control system based on commands in quasi-natural language.

On performance enhancement of parallel kinematic machine

This paper proposes a spatial three degrees of freedom (DOF) parallel kinematic machine enhanced by a passive leg and a web-based remote control system. First, the geometric model of the parallel kinematic machine is addressed. In the mechanism, a fourth kinematic link--a passive link connecting the base center to the moving platform center--is introduced. Each of the three parallel limbs is actuated by one prismatic joint, respectively. The additional link has three passive DOF, namely two rotations around x and y axes and one translation along z axis. With the existence of this link, the unwanted motion of the tool (located in the moving platform) is constrained. The fourth link also enhances the global stiffness of the structure and distributes the torque from machining. With the kinematic model, a web-based remote control approach is applied. The concept of the web-based remote manipulation approach is introduced and the principles behind the method are explored in detail. Finally, a remote manipulation is demonstrated to the proposed structure using web-based remote control concept.

A new fully automated FTIR system for total column measurements of greenhouse gases

Abstract. This article introduces a new fully automated FTIR system that is part of the Total Carbon Column Observing Network (TCCON). It will provide continuous ground-based measurements of column-averaged volume mixing ratio for CO2, CH4 and several other greenhouse gases in the tropics. Housed in a 20-foot shipping container it was developed as a transportable system that could be deployed almost anywhere in the world. We describe the automation concept which relies on three autonomous subsystems and their interaction. Crucial components like a sturdy and reliable solar tracker dome are described in detail. The automation software employs a new approach relying on multiple processes, database logging and web-based remote control. First results of total column measurements at Jena, Germany show that the instrument works well and can provide parts of the diurnal as well as seasonal cycle for CO2. Instrument line shape measurements with an HCl cell suggest that the instrument stays well-aligned over several months. After a short test campaign for side by side intercomaprison with an existing TCCON instrument in Australia, the system will be transported to its final destination Ascension Island.

Development of a web-based remote load supervision and control system

The ability to remotely acquire information and even to control appliances/devices at fingertips over the Internet is becoming desirable to the general public as well as professionals. In this paper, a web-based remote electric load supervision and control (WBRELSAC) system with automatic meter reading and demand control via programmable logic controllers (PLCs) is presented. For both utilities and industrial/commercial customers, the electric load supervision and control (ELSAC) system is a critical function to their load management. However, most high voltage customers do not have enough capital to build a regular-scale supervisory control and data acquisition system as the one for utilities. Therefore, we adopt the industrial-widely-used PLCs in WBRELSAC. In order to make a non-web-based PLC become web-controllable, we develop a graphical-control interface and utilize Internet techniques to implement our system. Based on the performance test conducted under the Laboratory environment, the proposed WBRELSAC architecture is cost-effective and suitable for industrial applications.

Design and implementation of Web-based diagnosis and management system for an FMS

Given the rise in competition within the global marketplace, the paradigm for manufacturing has changed dramatically. While downstream activities have become the focal point for global competitors, manufacturing remains at the root of a firm’s competitive edge. To remain competitive, firms are progressively shifting their manufacturing operations to overseas markets. Foreign markets offer a host of advantages to manufacturers but one of the obvious key advantages is cheaper labor. Even in industries where the required labor-to-capital input ratio is relatively low within the production process, lower labor costs allow the production of more competitively priced products. The emergence of this paradigm, however, has led to a number of managerial problems. Operating a manufacturing facility overseas creates difficulties for management both in the area of personnel and resource allocation. In this project we developed a Web-based remote control platform using digital cameras, a PLC controller and a PC-based Visual Basic human-machine interface (HMI) to create a flexible manufacturing system (FMS). An FMS can be easily controlled and monitored through an Internet-based PLC-control system using a PC-based HMI platform. From remote locations, this platform enables management to effectively monitor, control and diagnose a manufacturing process via the Internet.

The plant operation is configurable and programmable over a supervisory application executed along with a Web server. Among other features, the supervisory interface, displayed in the client browser, allows the remote on-line configuration of controller parameters and a real-time graphical visualization of process and manipulated variables. These features allow students to execute open and closed-loop multivariable control experiments.

자바를 이용한 웹 기반 원격 공압 서보 제어 시스템에 관한 연구

Recent increase in accessibility to the internet makes it easy to use the internet-connected devices. The internet could allow any user can reach and command any device that is connected to the network. But these teleoperation systems using the internet connected device have several problems such as the network time delay, data loss and development cost of an application for the communication with each other. One feasible solution is to use local and external network line for the network time delay, transmission control protocol for data loss and Java language to reduce the development period and cost. In this study, web-based remote control system using Java language is newly proposed and implemented to a pneumatic servo control system to solve the time delay, data loss and development cost. We have conducted several experiments using pneumatic rodless cylinder through the internet and verified that the proposed remote control system was very effective.
