Educating the world: a remote experiment in photovoltaics

The increasing deployment of photovoltaic (PV) systems requires large numbers of skilled engineers with a greater understanding of all aspects of PV teehnology both theoretical and practical. Developing experimental rigs at universities is expensive and limited to students physically attending the university. One recent approach to increase access to laboratories is the development of remote experiments. Here students can control real experimental equipment using a visual interface via the Internet. In this paper we explore the development of a photovoltaic laboratory to enable users to access and remotely control experimental equipment based at Loughborough University, UK, from anywhere in the world

The development of a photovoltaic remotely operated laboratory experiment: a contribution to meeting the challenge of the renewable energy skills shortage

Skills shortages are often quoted as a threat to renewables growth. The increasing deployment of photovoltaic (PV) systems around the world requires large numbers of trained engineers with a greater understanding of all aspects of PV technology both theoretical and practical. The development of experimental rigs at universities and training establishments is expensive and limited to students physically being present for time constrained activities. One recent approach to increase access to laboratories is the development of remote experiments. Here students can control real experimental equipment using a graphical user interface via the Internet. In this paper we explore the development of a PV laboratory that characterises PV panels under different environmental conditions. It enables users to access and remotely control experimental equipment based at Loughborough University, UK, from anywhere in the world via an Internet connection. We report on student experiences using the laboratory from distance

Conception générique d'un outil de configuration de « e-TP »

Powered by the technological advances of the “Information and communication sciences and technologies”, the Electronic Laboratory for Practical Training “ELab” (also known as ELab hands-on training) has become an inescapable teaching mode especially in the technical and scientific disciplines. Thus, several ELab modes have emerged: virtual ELab, remote ELab, Local Elab, augmented reality ELab, etc. The latter require the use of hardware devices (educational mock ups, measuring instruments, robots, etc.). In most cases, before or during an ELab session, these devices need to be reconfigured according to teaching purposes. For complex systems, like Automated Production Systems (APS), this reconfiguration process requires technical skills which the instructor does not have systematically. This imposes that a technician should be available, failing which the usage of the pedagogical platform will be limited to a few skilled instructors. Accordingly, this research aims at facilitating the reconfiguration process of complex systems (particularly the APS) featuring ELabs. A first survey designated to the users of « AIP-Priméca-RAO », located at the INSA de Lyon, has revealed the needs and constraints related to such a platform. It has been highlighted that beyond the (re)configuration process, a waste of precious time was detected. It has been established that it was due to the absence of a common tool for pedagogical resource management. This observation fed the design of a software tool managing an editorial chain aiming at simplifying creation, edition, assembling, organization, and the reutilization of different resources that can be exploited in an ELab session. This tool is also intended to improve the autonomy of the instructor during the preparation of an ELab session, by reducing the required time to configure this session. This implies to automate the reconfiguration process of an APS supporting the ELab and the publishing of the pedagogical learning scenarios on a Learning Management System (LMS). In order to validate this design, a prototype has been developed and tested on real Elab cases. Subsequently, this tool could be rendered more generic so that it can serve Elabs in different disciplines.Renforcés par les avancées technologiques des « Sciences et Technologies de l’Information et de la Communication (STIC) », les Travaux Pratiques électroniques « e-TP » sont devenus un mode d’enseignement incontournable surtout dans les disciplines techniques et scientifiques. Plusieurs modes d’e-TP ont émergé : TP virtuel, TéléTP, TP présentiel assisté par ordinateur, TP en réalité augmentée... ces derniers modes nécessitant l'usage de dispositifs matériels (maquette pédagogique, appareils de mesure, robots, etc.). Dans la majorité des cas, avant ou même pendant une session d'e-TP, il est nécessaire de (re)configurer ces dispositifs selon des besoins pédagogiques. Cette reconfiguration nécessite, pour des systèmes complexes, comme les Systèmes Automatisés de Production (SAP), des compétences que l'instructeur ne possède pas systématiquement. Ce qui impose la présence d'un technicien ou limite le nombre d'instructeurs susceptibles d'utiliser la plate-forme pédagogique. Ce travail de recherche a pour objectif de faciliter la (re)configuration de systèmes complexes, particulièrement les SAP, dans le cadre d'e-TPs. Une première enquête auprès des utilisateurs de l’« AIP-Priméca-RAO » (situé à l’INSA de Lyon) a révélé les besoins et contraintes liés à une plate-forme de ce type. Il s'est avéré qu'au-delà de la (re)configuration, l'absence d'outil commun de gestion des ressources pédagogiques faisait perdre un temps précieux aux utilisateurs. Ce constat a nourri la conception d'un outil informatique gérant une chaîne éditoriale dont le but est de simplifier la création, l’édition, l’assemblage, l’organisation et la réutilisation des différentes ressources à exploiter dans une session d’e-TP. Cet outil a également pour objectif d’améliorer l’autonomie de l’instructeur lors de la préparation de sessions d’e-TP tout en réduisant le temps requis pour configurer cette session. Cela a impliqué d’automatiser le processus de reconfiguration du SAP support d'e-TP, et de publication des scénarios pédagogiques sur un système de gestion d’apprentissage « LMS » (Learning Management System). Un prototype a été développé et testé sur des e-TPs réels afin de valider cette conception. Cet outil pourrait, ultérieurement, être rendu plus générique afin de servir des e-TPs dans d'autres disciplines

The technologic and industrial devices integration (Programmable Logic Controllers - PLC, several types of sensors and actuators, image processing, supervisory systems and robotic manipulation devices) in a single platform which is implemented following a modular Collaborative Automatic Production System (CAPS/ADACOR) architecture allows students and researchers to Interact with it by means of doing practices in order to successfully automate, supervise and manage a complete production process. Therefore, class acquired theoretical concepts are supported so improving user's professional skills. A platform developed using the here proposed generic structure allows users to work within an educational environment coping with most of the encountered aspects in a real Manufacturing Automation System, such as Technologic Integration, Communication Networks, Process Control and Production Management. Furthermore it is possible to command the entire assembly process taking place at the platform by a remote network connection using the internet - WEBLAB (Remote Laboratory), enabling individual users and groups in different places in order to use the platform and quickly interchange information. In addition it is important to outstand that both the Modularity and Flexibility of the platform can allow readily any further hardware or software enhancementMestradoMecanica dos Sólidos e Projeto MecanicoMestre em Engenharia Mecânic

AIP-Primeca RAO Remote Laboratories in Automation

During last decade, Internet and related web technology development enabled the arising of e-learning services and made distant learning a reality. As traditional face to face classroom became virtual classroom through Internet, traditional laboratories found their image in Electronic Laboratories (ELABs). These ones enable learners to train themselves on remote real or virtual systems. They represent essential components in e-learning environments, especially in scientific and technical disciplines. In this context, AIP-Primeca RAO is a pool of resources and competencies about industrial topics for many universities in Rhône-Alpes french Region. Due to the constraints inherent in using heavy and shared industrial resources, AIP is setting up new laboratories related to automation as both local and distant resources. After recalling the global context of e-laboratories, this paper describes this platform. It evokes first returns of use and it details evolutions to come
