One of the most dynamic branches of educational systems is linked with e-learning. In engineering, experiments play an important role in the learning process and, in general, impose student’s presence in laboratory in order to allow them to interact directly with instruments and objects under test. The paper presents some practical examples on how is possible to replace the traditional laboratory with a remote and virtual laboratory in the field of home appliance systems. The remote laboratory is based on two dedicated systems (named DomoControl128 and TinyDomots). Structure, main features and operational principles of current implementations are briefly presented.

This paper describes a basic electronics learning system combining a hypermedia system explaining theoretical concepts with a basic simulator and a virtual laboratory to improve the engineering education process on electronics and the students skills before going to the actual laboratory. To accomplish this objective the system also provides a set of complementary resources, constituting a bridge between theory and practice. This new kind of hypermedia tools takes advantage of the information technologies (multimedia, simulation, etc.) and also facilitates the self assessment of the students knowledge.

The work describes on-going work at the University of Pisa on the field of tele-laboratories and distance learning. In particular, the group is working at the evolution of existing tele-laboratory experiments in the field of robotics and control into learning units of a self-consistent didactic project. The pick-andplace system described has been designed to provide the set-up for robot arm motion planning with specific objectives and evaluation tools.

Organizing practical courses and training clearly indicates a demand for remote training. This article describes the concepts of the BACnet (Building Automation Control Network) laboratory being set up by the authors. To allow effective learning the control network (fieldbus) as well as the inputs and outputs of the nodes attached to the laboratory environment must be accessible by the trainee. To achieve this goal a web based application which uses a VNC (Virtual Network Computing) server and a special I/O interfacing unit have been designed. Hence, trainees will be able not only to monitor and control the activities on the control network (the primary goal of the offered courses) but also will be able to see the effects of their activities on the laboratory environment.

In this paper we present a remotely accessed experiment on industrial automation. Using this remote access, students may verify the correctness of their previous work and increase the productivity of laboratory classes. The experiment provides a web page for interfacing with a Programmable Logic Controller (PLC) which controls an electro-pneumatic process. Students may remotely download the program to the PLC and access to the PLC states and variables remotely, allowing the detection of semantic errors. Moreover a Webcam shows the image of the process which, not being essential, provides a more realistic view of the program correctness. The user has access to the system inputs through a web based Human-Machine Interface (HMI). This paper results from collaboration between a PLC solution provider and the university.

This paper presents an environment for monitoring and control of remote systems. The aim of this work is the development of software for virtual laboratories, and e-learning. The architecture based on a server and multiple clients, runs on a LabView® platform. Remote clients can monitor and control remote process models or real systems linked to the server, via the TCP/IP protocol. The Environment for Remote Control (ERC system), under development, is appropriate for control education and allows the use of different type of controllers, such as PID, Fuzzy, and others, implemented in the Matlab® language.

Laboratories for introductory digital system design courses have, commonly, high rates of laboratory’s space and time occupation. In this paper, a remote laboratory is proposed in order to alleviate laboratory’s occupation, although increasing the usage of their equipments by students. Local and remote accesses to the experiments are possible, supported by the LabView environment, and complemented by a specific virtual workbench adaptor to emulate user’s presence. Its usage for supporting experimentation around a set of experiments with a set-up based on the 8031 microcontroller was successfully tested.

When it comes about accessing an application remotely, that is from another computer than that where the application resides, the security should always be of concern. Because the connection between the two computers is done through a physical space, on which we may not have any control, whether that connection is through wires or wireless, we must be on guard of any possible identity and information stealing. This paper deals with the security aspect encountered in any remotely communication between two or more computers, connected among them through a physical or wireless connection. It explains the theoretical base and the implementation of these aspects in “Virtual Electro Lab”.

A two level client-server development was performed by web layer (to send remote measurement stimuli + simulation parameters) and workbench layer – implemented under National Instruments “LabView” control. The test bench equipment allows both programming of signals generation / acquisition and PSpice simulation triggering. MS “FrontPage”and Macromedia “Flash”based string concatenation and Intranet local links in the “Network Neighbourhood” allow direct publishing of the web page that groups simulation results with those of remote experiments.
